1 Introduction
Autism Spectrum Disorder (ASD) is a neurodevelopmental condition characterised by challenges in social communication and interaction and the presence of restricted and repetitive patterns of behaviour and interests [
9]. According to the latest estimates from the Center for Disease Control and Prevention, approximately 2.8% (1 in 36) children have been diagnosed with ASD [
32], while in India, the prevalence is found to be 1.12% (1 in 89) [
10,
107]. The increased prevalence of ASD has increased the burden on the global healthcare system to a great extent [
36].
Some of the standard therapeutic resources in ASD include technological interventions such as computers and tablets that help children learn various everyday activities to ameliorate their difficulty with social skills. Within the myriad of interventions available, social robots have emerged as a promising tool for technological interventions for CwA in enhancing the acquisition of everyday skills and as a means to enhance the overall quality of life [
39,
45,
83,
106,
121,
131,
140]. Roboticists define social robots as autonomous robots to which people apply a social model to interact with and understand them [
28,
97]. Researchers have explored the efficacy of Robot-assisted Therapy (RAT) to attain particular therapeutic goals for CwA. RAT, with social robots as interactive agents, are specifically designed to interact in a socially and emotionally intelligent manner, thereby enhancing the overall therapeutic experience [
124]. Robots endowed with verbal capabilities have resulted in better responses from children, where facial features and limb movements for such robots have been categorised as crucial elements for better developing a child’s gestures and expressions [
94]. Recent studies have also suggested that economically viable and easy-to-use toy-like robots have shown better therapy outcomes [
61] in clinical settings. However, the continuous development of such devices has been suggested for refining the various nuances of RAT after thoroughly examining the strengths and weaknesses of the device [
68].
Social robots in autism therapy often require collaboration with experts like special educators. While some educators have reservations concerning the privacy, roles and responsibilities of the robot, accountability of consequences of interventions and cultural bias about using them [
134,
142], many see benefits in terms of workload reduction and personalised care [
7,
154]. However, most research on social robots in autism intervention focuses on resource-rich communities in the Global North [
6,
42,
51,
110], which have better technological infrastructure and digital literacy [
89]. While the global utilisation of electronic devices in ASD therapy is well-documented [
23,
30], scholars like Diep et al. [
51] have argued that social robots are often limited to mechanical tasks, neglecting emotional and communicative dimensions. Along similar lines, researchers such as Rudovic et al. [
134] and Van Straten et al. [
167] contend that autistic learners require "predictability" and "consistency" in robots for optimal support.
In India, special educators echo global sentiments, endorsing technological aid in therapy [
148,
169]. However, disparities in technology adoption exist between the professional and private spheres, driven by cultural and accessibility factors [
35]. Alongside, there remains the rampant problem of financial shortcomings across almost all special schools and educational institutes, causing their professional fraternity to be divided into formal and informal categories [
76]. To address such issues scholars have highlighted the necessity of user-centered design approaches in technology building, coupled with sustainable business models and capacity-building initiatives that can support marginalised communities [
25]. Additionally, as many scholars argue that underrepresented populations in the Global South often face exclusion in technology development and analysis, it becomes necessary to acknowledge such a situation, as otherwise, one may limit the generalisability of findings and overlook the unique challenges and opportunities present [
114] in resource-constrained, digitally less-aware, or technologically under-equipped regions.
Addressing this concern, our study aims to understand the perspectives of special educators in India regarding social robots and their potential applicability within their professional practice. At the moment, figures provided by the Rehabilitation Council of India
1 show that there are 75686 special educators registered with the government body [
3]. They are known to provide caregiving services to various children on the autism spectrum. While some educators are affiliated with the government and private facilities, many provide door-to-door services. Since in India, despite the growing nature of technological advancements, robotic interventions in autism are still in their very early stages, it becomes crucial to understand if RAT would be pertinent and meaningful in the country’s socio-economic landscape. To achieve this aim, our study was structured around the following research questions:
•
RQ1: What is the nature of the present ecosystem of technology-enabled interventions for autism in India?
•
RQ2: What, according to the Indian special educators, are the perceived benefits and challenges of using social robots as therapeutic interventions for ASD?
•
RQ3: What initiatives can be taken to integrate social robots seamlessly into the Indian special education landscape?
To achieve this objective, we conducted preliminary surveys and field visits to gain insights into the current state of autism intervention services in India. Following this, we conducted interviews with special educators to explore further the context and specific needs within their daily practice. This was followed by hands-on workshops that allowed the special educators to engage with a social robot and a panel discussion with the educators and technology experts to collaboratively formulate preliminary and actionable guidelines for designing and developing social robots tailored to meet the specific requirements of such professionals in resource-constrained environments. Our findings highlight the paradoxical attitude of Indian special educators towards social robots for autism intervention. While enthusiastic about technological innovation, they face challenges like high costs, fears of job displacement, and concerns related to personalisation, linguistic limitations, and over-commercialisation.
Drawing upon these findings, we assemble crucial insights for designers and developers interested in introducing social robots for autism intervention in the resource-constraint settings of India. Additionally, we shed light on the intricate identity challenges experienced by special educators in this region due to the incorporation of social robots into their practice. Lastly, we emphasise the need to alleviate educators’ scepticism through enhanced dialogue and public awareness, a role that government agencies should actively support.
3 Research Methods
3.1 Positionality and Reflexivity
All the authors are of Indian origin. The authors are well aware of and exposed to the constraints surrounding different kinds of resources in the Indian socio-economic landscape. One of the authors is a special educator with 15+ years of experience working with CwA. Three authors have previously conducted studies in human-computer interaction (HCI) in the context of socially assistive robots for autism. Two authors have experience working with community-based approaches towards computing and design. To mitigate potential bias stemming from authors’ familiarity with work contexts, we pre-registered our methodology at the study’s commencement, promoting transparency and reducing bias risks in analysis. Furthermore, we emphasise the diversity in our authorship, which spans various backgrounds, to counteract individual biases. However, we recognise the inherent challenge of our strong desire to enhance the state of special education, which may influence our data analysis. We ask that our paper be read as such.
3.2 Ethical Considerations
Ethical approval for this study was obtained from the Institutional Review Board (IRB) of Indraprastha Institute of Information Technology (IIITD) (IIITD-IRB/FR/01/2022/04). Before the interviews, the participants were provided with an overview of the study and verbal and written consent was obtained. Participants were allowed to converse in Hindi, English, or Bengali based on their preference during the interviews.
3.3 Participants and Recruitment
The study was conducted in urban settings within Delhi and Kolkata, two metropolitan cities in India, from February 2022 to June 2023. The study comprised 25 participants who were licensed special education practitioners (F=22, M =3, Age range (years): 24-58) in these cities, possessing at least five years of experience working with CwA registered with the Rehabilitation Council of India (RCI). RCI is a statutory body that regulates and monitors services given to persons with disability and maintains the centralised register of qualified professionals and personnel in the field of rehabilitation and special education. Informants were contacted and recruited through professional organisations, special schools, and rehabilitation centres using a combination of email solicitation, snowballing methods, and the authors’ contacts. The recruitment did not consider the participants’ prior experience with or knowledge of technology or robotics-assisted interventions to mitigate potential bias in the study. However, many participants mentioned routinely incorporating some form of technology into their work. Each of our informants had extensive experience (Mean experience (years): 13.4) working with CwA. Appendix
A presents the demographic information of our participants.
3.4 Methodology
3.4.1 Field Trips and Groundwork.
Prior to data collection, the authors conducted extensive field visits to 4 rehabilitation centres in Delhi. At each centre, three authors conducted several field observations to understand the various activities and strategies that special educators working with CwA regularly use. Extensive notes and schematic sketches were developed to understand and document special educators’ activities. Special attention was also paid to understanding how different tools and technologies were used in these activities. Care was taken to ensure our field visits were not disruptive to the children’s daily routine. No photographs or videos were taken to ensure the privacy of the children. As elaborated in subsequent portions of the methodology section, these field trips were invaluable for us to familiarise ourselves with the educational activities, rehabilitation strategies, work routines, and the challenges they face in their day-to-day professional lives. The data collected during these field visits was extremely useful for programming our NAO robot deployed to carry out the demo RAT activities, developing our semi-structured interview guide, and setting the workshop agenda.
3.4.2 Study Materials.
Video for Elicitation Activity. Video provocation has been previously employed in literature [
99,
105] to educate participants about the technology. Building on previous research, we employed video provocation to educate special educators about the capabilities and potential use cases of robots in interventions.
Based on our field observations, interactions with the special educators, and an extensive review of literature, we identified the most common set of activities performed with CwA across the globe and in India. The final set of exercises selected was as follows: response to name, emotion identification using card matching, imitation, vocabulary building, and making eye contact using a peek-a-boo game. This set of exercises was widely used by special educators in India. These exercises were derived from a therapeutic approach based on applied behaviour analysis (ABA), commonly used to improve social, communication, and learning skills in individuals with autism [22]. This approach utilises reinforcement techniques to encourage the development of desired behaviours and skills. ABA is an evidence-based and scientifically validated practice that has been demonstrated to be effective in enhancing the abilities of individuals with autism and other developmental disabilities. Taking these activities as a basis, we programmed an interactive social robot agent - the NAO robot, which is a widely used robot in autism research [
11,
154,
162] to deliver intervention activities to CwA under the guidance of a special education expert. The robot was programmed to speak in Hindi (a native language widely spoken in North India, where the study took place).
Centred on the study’s goal, the primary aim of the video was to emphasise the application of robots in intervention activities rather than highlighting the interactions between robots and the child. Consequently, we trained a seven-year-old non-ASD child to engage with the NAO robot and carry out the specified activities. Subsequently, a video with English subtitles was created of six RAT activities (response to name, joint attention, imitation, vocabulary, emotions, anticipation play) outlined above to inform special educators about the potential use of robots in therapeutic practices. The video showcased both positive and negative use cases of using robots in such settings. One example of a positive use case demonstrated in the video was when the robot successfully completed a task without any errors. On the other hand, a negative use case was showcased where the robot failed to complete an activity due to technical glitches or hardware limitations. The exploratory video was of ∼ 10 minutes in duration.
3.5 Procedure
The study protocol incorporated a qualitative research approach, combining video provocation/elicitation with semi-structured interviews, workshops and panel discussions. The study unfolded in three phases.
Phase I: Video Presentation. Participants were contacted at their preferred time, either in person or through Zoom. In the beginning, one researcher briefly explained the scope of the study, shared the study information sheet and obtained the participants’ consent. Then, the author presented an overview of NAO robot-based intervention activities and presented the exploratory video to them. Exploratory videos were used to elicit participants’ responses and gain insights into their experiences and perspectives. Conti et al. utilised both video and oral presentations in their study to assess the readiness of psychologists to incorporate robots into their professional practice [
42]. Previously, to examine the perceptions of Community Health Workers (CHWs) about integrating AI into their workflow and identifying the anticipated benefits and challenges, video provocation was utilised as an exploration artefact by Chinasa et al. [54]. Based on this previous work, in this study, we use video elicitation to inform special educators about the possibilities and challenges of incorporating social robots into their educational interventions for CwA. Snapshots of the video are presented in Figure
1.
Phase II: Semi-structured interviews. Once the video presentation had concluded, the informants participated in a semi-structured interview. The interview protocol was structured around four thematic categories: a) background of the educators, b) challenges and concerns faced by educators in facilitating routine autism interventions, c) exploring their perceptions regarding the usability of robots in interventions, and d) understanding perceived trust and meaningfulness of social robots in the Indian context. As recommended by Jacob and Furgerson [
73], after each interview, we systematically reviewed and revised the questionnaire, incorporating additional prompts and follow-up questions. This iterative process continued until we reached saturation, ensuring the gathered information was comprehensive. The interview protocol is given in Appendix
B. The interviews were conducted in Hindi, English, or Bengali according to each of the participant’s language preferences and lasted 1 to 1.5 hours.
Phase III: Expanding on the insights acquired during the interviews, the study’s third phase included three one-day workshops for educators, providing them with hands-on experience with the robot. This was followed by a single panel discussion, which brought together special educators (participants in our previous interviews) and technologists, including developers and researchers specialising in social robotics and artificial intelligence.
Workshop. In each of these workshops, we facilitated the special educators to interact with the robot. The participants were afforded the opportunity to actively engage with the robot and experiment with the activities demonstrated in the video probe. Participants had the freedom to choose activities based on their preferences, and each participant performed at least four out of the six activities. Participants who did not complete all the activities mentioned reasons such as being technically unfamiliar, while a few found certain activities to be less challenging. During this time, we also answered any of the questions that they had in their mind. Each session had 8-9 participants and lasted between 1 to 1.5 hours. The screenshot from one of our workshop sessions is given in Figure
2.
Panel Discussion. Following the workshop, we extended invitations to these participants for a panel discussion to explore the future possibilities of integrating robots into autism intervention. Upon receiving confirmation of participation, the panel discussion was conducted one month after the workshops. It involved 14 special educators from the previous participant pool and four technology experts. The inclusion of panel discussions in the study protocol aimed to develop guidelines that are grounded in the specific needs of special educators and the technological feasibility of implementation. Throughout each session, participants were actively encouraged to share their ideas on how robots could be better built and designed to enhance integration, particularly in resource-constrained settings like India. Furthermore, they were prompted to articulate their perspectives on the role of robots in interventions and were encouraged to present and justify their views in an explainable manner. The sessions also saw many of our special educators provide us with pictorial depictions of social robots as they imagined themselves, as shown in Figure
3. It’s crucial to acknowledge that design considerations were outside the scope of this study; nonetheless, their visualisations were taken into account to gain insights into their perceived role of robots in interventions. The technologists who formed a part of our panel discussion belonged mostly to research institutions across India and had an average experience of nine years in ideating, building, and maintaining assistive technologies.
As we took field notes from these conversations, every workshop session and panel discussion was audio-visually recorded with prior permission from all the respondents. The recordings from these sessions were transcribed for the purpose of further analysis. For taking part in these three sessions, participants were compensated with a 700 INR (∼ USD 8.4) Amazon gift card.
3.6 Data Collection and Analysis
The data included 25 semi-structured interviews (∼ 50 hours of audio) and ∼ 5 hours of video recordings of the three workshops and panels. Data also included detailed field notes made during the field visits, interviews, workshops, and a panel discussion. The audio recordings of interviews conducted in Hindi, English, and Bengali were translated and transcribed into English for analysis. For coding, the transcripts from interviews, workshops, and panel discussions were initially treated separately and first-level codes such as
"sharing of resources",
"robots are more animate than tablet", etc. were extracted based on the emerging patterns in data. Each author independently analysed and open-coded the data using thematic analysis employing an inductive, constant comparison method [
27]. Following this, we proceeded with the second iteration of open coding, identifying commonalities within the initial sets of the code list from different phases. To ensure accuracy and consistency, the authors periodically met to compare the codes being generated, resolve any discrepancies, refine them and conceptualise themes to a higher level, such as
"Special educators talk about financial difficulties",
"Social robots can be partners in different activities", etc. We repeated this process until all the interviews were coded, we reached data saturation, and all authors reached a consensus on the identified themes. The final codebook with derived themes and the frequency of each code are presented in Appendix
D. To protect the privacy of our participants, we used pseudonyms and anonymised the quotes in the manuscript.
4 Findings
This section is organised as follows. We begin by answering the first research question by highlighting the current socio-technical contexts of special education schools (Section 4.1) and the challenges that therapists face when using various technologies in their daily practice (Section 4.2). Next, we document Indian special educators’ perspectives on the perceived benefits and challenges of using social robots as therapeutic interventions for CwA (Section 4.3) and the perceived transformation of their roles in therapy (Section 4.4) to answer the second research question. Lastly, to answer the third research question, we explore the initiatives that can be taken to integrate social robots into the Indian special education landscape (Section 4.5).
4.1 Current Socio-Technical Landscape of Special Education Schools
To understand and situate our work in such realities, we requested our interviewees to articulate the intricacies of their work environments. Our interviews revealed that nearly all the schools we investigated possessed fundamental infrastructural facilities, including essential tools for therapy. While some institutions managed to distribute these devices adequately, many centres had inadequate technological resources and a large number of faculty members or students who used them, thus creating a scarcity. For instance, respondents P12 and P13 highlighted that their school lacked devices such as laptops and tablets due to limited donor funds, which only covered locally manufactured desktops with outdated software, which limited their use.
“ Our donors have made it explicitly clear that they do not want to invest all their money in hardware and software. Over time, we requested them for another PC, but our request was denied. ” (P12)
Distribution Hierarchies and Educator’s Sentiments. Special education centres often employed creative strategies for addressing such deficits when resources were inadequate. For instance, respondents P1 and P2 highlighted that a rotating system was implemented every week in their school that ensured that nearly all teachers, regardless of their positions, could use technological equipment at least once every two weeks. These workarounds involving the sharing of devices have emerged as a common practice to overcome the lack of adequate resources in the Global South [
122]. In addition, some participants also pointed out that factors like individual therapists’ proximity to the centre’s head and the attrition rate of children in their groups often influenced their access to and allocation of technological resources.
“Despite the policy for rotational equipment use, it often appears effective only on paper, influenced by proximity to the head and children’s attrition affecting favour. High attrition is seen as the educator’s inability, with no explanations permitted.” (P1)
Educators, Conflicts and Emotional Impact. The challenges stemming from insufficient technological resources seemed to result in various conflicts among educators, resulting in a personal sense of dissatisfaction. For instance, respondents like P23, P24, and P25 conveyed their frustration around the scarcity of resources, noting that it occasionally led them to question their professional purpose and triggered feelings of being "unwanted" and "undesired." In many well-funded schools, we also observed that the special education classrooms were segregated into distinct areas within the regular institutions, amplifying these feelings. As highlighted by several respondents, this sense of othering was especially pronounced when they were physically segregated and denied access to basic amenities like internet connectivity, thus necessitating them to look for alternative arrangements.
"The setup appears odd to me. Our centre is part of the school, which caters to both neurotypical and neurodivergent children. I don’t understand the need for a separate building outside the main premises. Teachers from there don’t engage with us or share resources. We even have our own internet connection." (P23)
4.2 Understanding Educator’s Needs and Challenges with Technology-Assisted Interventions for Autism
The therapists we interviewed employed a range of technological interventions for therapeutic purposes. These included Android applications such as
Avaz and
Talk With Me4 to enhance speech, specifically curated YouTube videos to bolster social skills and vocabulary acquisition, and the integration of electronic toys and hand puppets to help with conversational interactions. Additionally, confident special educators utilised computer games installed on their centre’s PCs to facilitate the learning of everyday activities. On the one hand, several therapists appreciated the value these technologies bring to their therapeutic practice in terms of enhanced learning outcomes. At the same time, they also expressed several apprehensions, as outlined below.
Expensive Machines and Educators’ Frustrations. Several interviewees (n=13) revealed that using expensive devices like tablets and PCs was always risky and made them anxious. One special educator, P23, informed us that often, some centres and schools were “ruthless” and asked the educators to compensate for any damage done to the devices. P13, P18, and P23 acknowledged that such a policy fostered a perception that the institution lacked complete trust in their educators and prioritised the economic value of the devices over their expertise in delivering services using such devices.
“When I have to constantly worry about the chances of a portion of my earnings being deducted whenever I use a device, my frustration is directed more towards the device itself than the centre’s trust in my responsibility. After all, it’s all because the device is expensive, right? ” (P13)
Challenges in Therapy Applications. Our interviewees had mixed opinions about using different therapy software. Some were concerned about the language options in popular apps like Avaz, which only offered seven Indian languages. Some interviewees felt this to be a lack of inclusiveness that showed a disregard for cultural and linguistic diversity across India. Some participants disagreed when discussing the feasibility of incorporating a large number of languages to be slightly difficult, suggesting that such apps were constructed without considering inclusiveness. At least three participants complained that such applications needed very powerful mobile devices with high storage capacities, and their inability to own such devices prevented them from using these Apps. Two other participants who worked independently providing door-to-door services found that subscribing to these applications was too expensive, and owning a mobile phone that would support such apps would add more cost to their practice.
“I have used the app called Avaz. I hear a lot of people using it these days. I have used other software as well. The problem with these technologies is that they lack in multilingual setups.” (P7)
Technologies for Alleviating Fatigue in Autism Therapy. Reflecting on their professional challenges, our participants echoed narratives underscoring the pervasive issue of fatigue and emotional drain among educators. The repetitive nature of autism therapy tasks, coupled with extended periods of managing children with special needs, is noted as particularly demanding and emotionally taxing [
29,
82]. Given these factors, our respondents expressed that they would find it helpful if technological interventions could be developed to share their work burden and alleviate their stress and fatigue.
“We do the same tasks every day, and it makes us exhausted. It would be good to have technologies that can share this exhaustion.” (P4)
Needs, Requirements, and a Call for Collaboration. A common consensus that emerged among the experts we interviewed indicated that existing technology-mediated methods were falling short of meeting educators’ needs across different contexts and circumstances. Particularly concerning software applications, they noted that these tools appeared to prioritise "the needs of the affected children" without adequately considering the operational capabilities and needs of the experts themselves. Nevertheless, despite facing several challenges, none of our participants were reluctant to use technological tools and applications for therapeutic interventions. Many special educators stressed the importance of collaborative tool development rather than merely critiquing technology for its inherent limitations. This sentiment was shared by experts across the spectrum, including both independent therapy service providers and those who work at institutions.
4.3 Educator’s Perspectives on Benefits and Challenge of Robot-Assisted Therapy
In this section, we elaborate on the sentiments expressed by our participants about integrating social robots in their therapeutic practices and establish whether the latter would be a meaningful addition to the existing technological interventions.
Following the video demonstration, our respondents were prompted to share their opinions about the robot’s engagement in diverse therapeutic activities. Many of our participants appreciated that social robots could replicate many therapeutic exercises they conducted regularly. Sixteen of the twenty-five therapists we interviewed confirmed that such technologies “defined the future of autism therapy.” A few others remained “optimistic” about seeing if future robotic technological developments will address the specific needs of special educators, as this would increase the uptake and use of social robots in therapeutic practice.
“I am quite fascinated with how it works and understand everything. I think it is going to be really useful for the children as well as for myself. Unlike a tablet or a computer, this seems quite animate and should do well with the kids.” (P21)
Anthropomorphism and Perceived Benefits in Therapeutic Practice.
The anthropomorphic characteristics of the social robot captured the attention of almost all the participants. Some of them even projected their ideas using their drawings during our workshop sessions, as depicted in Figure
2. A few even pointed out that using social robots in therapy would be similar to their existing use of sock puppets that mimicked human-like features. Mirroring the participants’ views in Duffy’s study [
54], several of our participants also agreed that incorporating human-like attributes would make working with robots easier than with other software tools or digital devices. Without exception, all the participants highlighted that the presence of humanoid traits made them perceive the robot as a "partner" capable of "walking and talking" and "interacting" like humans. Research also shows that the anthropomorphic attributes of social robots influence people to perceive them to be more sociable [
81], leading to increased likability [
31]. Some special educators, like P9 and P10, said that programming the robot to talk in Hindi and not English was a good step and an important one in countries like India, where many people don’t speak English. With the robots being able to speak Hindi, the educators felt that they would be “at ease” and “socially connected” while using the technology, which was crucial for the therapy process. Perceiving social robots to be similar to a helping hand, special educators also explained that participating in therapeutic activities with a robot by their side would make them more “confident” and feel more “empowered” when working with the children.
“Working with a Hindi-speaking robot would make me feel very proud and comfortable. I would know that I at least have an assistant with me who can perform some of my tasks if I am too fatigued. I would know I am not alone in this. Plus, I would always prefer a robot which looks more like a human.” (P9)
Robots as the Non-Judgmental Aids. After learning that special educators contemplated utilising social robots as therapy partners and assistants, we proceeded to delve deeper into their rationale for envisioning social robots as work partners. We were especially interested in understanding if only their humanoid characteristics bolstered educators’ confidence or if other factors influenced their decision. In response to this question, our participants pointed out that it did not matter if the robots were capable of actual human emotions or, for that matter, whether they had any sense of camaraderie towards their users. Instead, what mattered to them was a human-like entity that acted as a support system and could help in some of the exercises and activities consistently without fatigue and without exhibiting any prejudice or discriminatory behaviour towards the patients or causing physical harm to them.
“When called for assistance, our aides would sometimes think of us as incapable of working independently. I think a robot like this serves my purpose and, at the same time, will not judge me for using it as a helping hand.” (P24)
Regulating Robot Engagement in Therapy. While acknowledging the importance of robot-assisted interventions for ASD patients, our interviewees also stressed the importance of finding the right balance between the level of human and robotic engagement in providing therapy. In this direction, several special educators pointed out that one way to achieve this was to deploy social robots customised to support specific repetitive tasks in their therapeutic routines under their supervision. Several participants saw this ability of social robots as potentially useful tools to reduce their workload and alleviate mental stress and fatigue, in concert with findings from previous studies [
153].
“We get psychologically drained after our consultations. With this robot, I think I could escape from some of that. I could ask my assistants then to conduct some of the sessions for which the robot could be helpful.” (P6)
Robots Could Lead to "Over-Professionalisation." Senior experts in our study expressed the need for educators in India to have a strong moral sense while working with social robots. This is in concert with previous studies in human-robot interaction (HRI) exploring ethical and accountability dimensions where researchers have highlighted the need for educators to be responsible towards the appropriate use of social robots [
158]. These experts speculated that introducing social robots, like tablets and smartphones, might lead special educators to prioritise enhancing their professional identity and marketability over using the technology to benefit their patients. Therapists in our study also voiced concerns about the potential impact of robotic interventions on their capacity for empathy toward the children they work with. They were worried that over-reliance on social robots could lead to disregarding social and cultural issues faced by CwA such as stigma [
48,
112].
“Computers initially gained popularity more for trendiness than therapy. Although not all educators were swayed, parental demand sometimes fueled market-driven approaches rather than thoughtful planning. Introducing robots could likely elevate professionalism for those who can afford them, potentially skewing therapy towards economic interests.” (P9)
Concern for Damages and the Fear of Technical Complexity. In line with their anxiety about dealing with expensive digital devices, as elaborated in section 4.1, concerns among educators were also related to affordability. Explaining the rationale behind their apprehension towards social robots, participants like P1 and P2 articulated that, similar to other devices, their schools could ask them to pay for any damages inflicted on the robot. The educators were also concerned about the technical complexities of handling a social robot. They asked us if the therapy exercises could be controlled through an easy-to-use mobile application as per the needs of a child.
“I do not doubt the capabilities, just that using it would be risky if the kids throw it away or damage it. I might be asked to pay for the damages.” (P2)
4.4 AI, Robots and Role Transformation: Fear of Replacement and Strategies for Collaboration
In this section, we discuss some of the anxieties and fears expressed by our participants to highlight the necessity of user perception in human-AI collaboration [
127], with the hopes of contributing to developing artificial intelligence-based technologies with a human-centred and responsible approach.
Fear of AI for Personal Reasons. On the same lines, concerns about potential job loss due to replacement by social robots emerged as a common theme in several of our interviews and panel discussions. In response, we explored the reasons behind these reservations to alleviate their fears and to draw insights and implications for the design community to address this issue from a practice perspective.
“As I am seeing technologies like ChatGPT become more and more a part of everyday life, I fear that, soon, robots like these could make us redundant. I was discussing this the earlier day with a colleague of mine, and even she felt the same way.” (P10)
Our interviews revealed that much of the fears and anxieties of our participants were rooted in their in-direct experiences of seeing family members being laid off due to the introduction of computers, being exposed to speculative technology news reports, hearing stories of friends and distant relatives struggling to adapt to technological systems in industrial settings and personal experiences of losing occupational status with the introduction of technology-enabled therapeutic routines. Several respondents perceived robotic technologies as a force that only "devalued their work" or rendered their roles unnecessary.
“We suffered a lot as a family when both my parents lost their jobs. Their job was mostly administrative pen and paperwork. The problem was with the introduction of computers. My parents did not know anything about them, and the company office thought they were not needed anymore. That left me completely traumatised.” (P11)
Taking a slightly different view, while admitting to her family member losing his job due to automation, participant P19 nevertheless advocated for using sophisticated technologies like robots in a controlled and collaborative manner.
“I like this robot; it’s not like I don’t like it. I am a bit sceptical. I have witnessed my father lose his job in the factory because of automation." (P16)
Collaboration for The Greater Good. Though ideas for collaborating with a social robot ranged across different tasks, almost all the therapists agreed that robots are highly beneficial in conducting therapeutic exercises that involve repetitive tasks designed to improve joint attention and imitation. They reasoned that it would make the process more enticing and appealing to CwA and reduce fatigue associated with repeated tasks for practitioners.
“I think for joint attention or imitation exercises, I can work out the robot to ensure better child engagement. Autistic children usually like these things and find them to be very attractive. I imagine in such cases, I and the robot can both do the exercise in unison, and then the child can follow. I could maybe do a couple of jumps with my hand, and the robot can do the rest.” (P7)
Further, many participants suggested that robots could perform a part of a particular task by themselves and let the educator complete the rest in a collaborative, iterative manner. These ideas we gathered from our participants were consistent with those documented in other related studies [
7,
80]. Another critical area in which our participants found robots potentially useful is training special educators. Participants P9, P16, and P22, who owned their special education schools, proposed that social robots could be deployed to help young professionals practice therapy activities before they start working with CwA. They even enquired from us if the technology could be developed in such a way that it could assess an educator’s capabilities before the individual is assigned to a working group.
“I think apart from doing the tasks, I could even make this work for teaching the educators themselves and letting them practise with it before they work with the children. Some educators have difficulties in working with children immediately after training, so this might help them in acclimatising with the environment of therapy.” (P5)
Two highly experienced experts discussed the possibility of using social robots as "positive behaviour influences" for CwA. Their emphasis was on robots being pivotal in cultivating socially acceptable behaviours, particularly when children resisted guidance from special educators. More importantly, these experts firmly believed that robots could foster a constructive experience for children and educators during therapy sessions. Lastly, drawing on their experiences, these senior practitioners gently dismissed the fears of facing obsolescence. They asserted that the role of special educators might transform in the years to come, fueled by the advent of robots. Rather than harbouring fears about being replaced, they advocated a proactive approach to harnessing technology and exploring innovative collaboration avenues to co-opt social robots in their practice.
“I believe the special education profession would have a different purpose and meaning with the rise of technology these days. I do not think it is going to wither away. But at the same time, we need to adapt to technology instead of simply postponing its use. Personally, I would advocate the use of social robot systems, but at the same time, our professional community has to work together to make it a prudent addition to their work.” (P16)
4.5 On Trust, Belief and Reliability: Negotiating Meaningfulness of Social Robots in India
Previous research shows that understanding how users perceive technology in terms of trustworthiness and user-friendliness can be crucial to its successful implementation and use [
40]. As social robots are relatively new in India compared to other assistive technologies, we agree with Kok and Soh’s submission that it is crucial to investigate perceptions about their safety and reliability directly from their users. The section below documents our participants’ conceptualisation of such crucial aspects to expand the scope of the broader HCI work revolving around user perception surrounding trustworthiness [
20,
173] and making social robots meaningful [
111] and appropriate for a professional setting [
137].
Understanding Trust, Inequality, and Fragmentation. In our study, many special educators acknowledged the potential of robots as beneficial additions to their work. However, they also expressed concerns about their appropriateness, citing India’s economic conditions and social inequalities. Such ambivalence in opinions has been reported in other studies as well [
159,
160]. Some educators, like P12 and P18, expressed that robots might worsen existing differences, contributing to their hesitation despite recognising the technology’s potential. Our findings align with previous work reporting similar attitudes that were due to factors such as anticipated issues of trust in robots [
56], reluctance to embrace new technologies due to a negative bias [
57] and a belief that technologies can be harmful to the society [
21] emerging from personal first-hand experiences.
"There is already so much inequality in our country. I feel with this robot, those differences might get amplified." (P19)
Twenty out of the twenty-five interviewees highlighted two trust-related issues. First, they hesitated to accept social robots as trustworthy as they believed that it might cause them to be undervalued in a society where they were already marginalised despite their professional acumen. Secondly, recognising the differences within their fraternity, they believed that social robots could cause further divisions and may lead to financially well-off special educators looking down upon those who provided “door-to-door services” who were sometimes labelled as "not really professionals" or "pseudo-experts."
"The introduction of a robot could amplify existing inequalities in our profession. Those with access to robots could enhance efficiency, income, and prestige, while others struggle to earn a living. In India, our professional community is polarised, and I can’t fully endorse robots considering these dynamics." (P20)
Interestingly, some of the educators we spoke to linked the inequities ingrained in their profession to the broader social divisions in the country. They informed us that they preferred using "simple" tools without extravagant features since they believed it could potentially worsen societal and professional divides. One respondent, P11, particularly attuned to prevalent discrimination based on factors like caste and class, expressed reluctance to adopt technology that might accentuate these differences. Echoing these concerns, our participants suggested restrictions on the long-term use of robots in special education.
“I think, in a country like India where inequality is everywhere, I cannot knowingly let a machine disrupt the already fractured environment of my profession. If that happens, then the entire community will have to suffer, and the children will suffer more." (P22)
Support for Robots as The Future of Therapy. Educators supporting the assimilation of social robots into therapeutic interventions presented different reasons. In our study, participants P8, P11, and P13 underscored humanoid features and demonstrative abilities of social robots as crucial indicators of their positive outlook. They emphasised that the robot’s impact on the child was pivotal in the Indian context, assessing the demonstrated features’ appropriateness and utility. Participants like P10 and P16 highlighted that futuristic technologies like robotics were inherently trustworthy, seeing their success in other countries for RAT. They also embraced innovation despite poverty and inequality, foreseeing long-term benefits. They drew parallels to how computers and mobile phones, once expensive novelties, became everyday essentials, thus projecting a similar trajectory for robots.
“We are standing at such a time when India is growing as an economy, and of course, like every developing nation, we have our own problems. But that does not mean I will not support something for the children. As a professional, I am not afraid to say I fully support social robots.” (P8)
Training Special Educators for Using Social Robots. The two veteran special educators, P16 and P22, expressed that while robots might find utility and relevance in Indian settings, concerns about the use of such technologies arise with regard to their proper knowledge of handling and operation among professionals. Noting that technological interventions in autism therapy remain insufficiently accessible in rural and semi-urban areas due to a lack of proficient professionals, they emphasised the potential for mismanagement of these interventions in these contexts due to inadequate training and the risk of mishandling expensive devices. Hence, these experts called for adopting appropriate training programs advocating for government and civil society collaboration to ensure effective technological interventions among marginalised communities.
“I wholeheartedly support the use of social robots. From my experience, it would be my opinion that the government should work with NGOs and scientists to explore the options of making these cost-effective and widely available with sufficient training resources." (P16)
5 Discussion
Despite increased efforts to develop social robots in resource-constr-ained settings like India, limited progress has been made in understanding the needs and perceptions of end-users regarding robot-assisted interventions, with only a few studies addressing these aspects [
13,
87]. Earlier implementations of technologies in low-resource clinical settings have demonstrated failures, resulting in added inefficiencies to clinical workflows and, at worst, the harm inflicted upon the communities they aim to benefit [
19,
47,
67] necessitating proactive examination before deployment [
105]. This is particularly crucial for addressing the vulnerability and marginalisation experienced by professionals in resource-constrained settings in the Global South, as observed in previous studies [
142].
In our research, we aim to ensure social equity and justice in perception-oriented investigations of HRI, contributing to the glaring absence of scholarship in HRI literature. Organising our findings, the discussion section is structured into three segments: a) highlighting implications for designing social robotics in resource-constrained settings, b) providing guidelines for preparing educators in robot-assisted interventions, and c) suggesting institutional strategies for seamless integration of social robots in autism intervention.
5.1 Design and Development of Social Robotics for Resource Constrained Settings
In our endeavour to devise a robot-assisted therapeutic system tailored for resource-limited communities, the study underscores the need for a cautious approach in deploying robot-assisted therapeutic systems, emphasising educators’ pivotal role in decision-making during therapy. The suggested strategies involve creating culturally suitable and lightweight activity modules, ensuring multilingual capabilities, endorsing open-source moderation, prioritising the improvement of existing applications rather than introducing entirely new systems for smooth integration into educators’ routines and employing participatory design to ensure contextual appropriateness.
5.1.1 What should developers keep in mind while creating social robots?
Our findings underscore educators’ preference for a clearly defined
strategic role in robot-assisted interventions, emphasising the enhancement of their efforts in the therapy process. To align with this preference, developers, as suggested by Elbeleidy et al. [
55], can focus on creating robots with reduced autonomy, fostering improved collaboration between humans and robots. To further address educators’ insecurities, we propose involving them in the decision-making process during therapy, promoting confidence and mitigating potential complications in the event of technical failures. We also find it crucial to present the social robot as a peer or role model for children [
87] as well as a non-judgemental aid, prioritising cost-effectiveness and robust build quality. To this end, we advocate for industry engagement in producing low-cost, durable devices that ensure longevity. Such an approach not only addresses concerns but also reduces fear, fostering the acceptance of advanced technologies, especially within marginalised communities, in a confident and approachable manner [
152].
In light of our findings, prioritising cost reduction while preserving the social robot’s functionality emerges as crucial.
Accessibility, particularly for educators managing RAT, becomes a focal point [
145]. Prior studies in the Global South have explored initiatives like using mobile phones to enhance online accessibility [
117], reduce poverty [
155], and provide free basic Internet connectivity [
34]. Given the prevalent ubiquity of smartphones in marginalised communities, the limited digital literacy among educators, and storage challenges reported by our participants, a lightweight mobile application featuring an intuitive interface [
125] stands out as a potential solution. Such an application could facilitate the curation of therapy exercises without necessitating direct robot reprogramming. Furthermore, we underscore the significance of integrating robotic intervention seamlessly into existing practices. This strategy avoids the imposition of an entirely new intervention approach tailored exclusively for robots. By adopting this approach, the transition from current tools to the incorporation of social robots into daily practice becomes smooth and natural.
Drawing from existing literature [
1] and the input of our educators, we recognise the
diversity in the needs of children on the spectrum. We thus advocate for flexibility in designing activity modules [
8,
26], accommodating unique requirements and allowing for future improvements. Additionally, these applications should enable educators to customise and personalise therapeutic experiences for each child, aligning with fundamental autism therapy guidelines. Inspired by Barba, we also recommend making activity modules open-source by the companies developing social robots in order to promote transparency and reproducibility and allow for its iteration by educational institutions and non-profit research labs [
16].
Educators also stressed the importance of ensuring
cultural appropriateness in the robot’s activity modules, e.g. such as performing positive reinforcement through clapping of hands and not by giving a flying kiss. Recognising the significance of aligning technology implementation with cultural understanding, as emphasised by Gross et al. [
63], we follow Pal et al.’s approach to assistive technology in emerging regions and propose a collaborative design process involving professionals such as computer scientists, engineers, cultural theorists, interaction designers from various geographical contexts, and caregiving professionals in diverse regions [
144].
Our educators also expressed the need for robots to communicate in vernacular languages beyond English. It’s therefore recommended that these robots possess multi-linguistic capabilities, considering the diverse linguistic landscape in countries like India and the Global South, with the aim to include non-prominent vernacular languages as well in the future. Additionally, based on the perspective of some of our participants, we suggest that new applications for robot-assisted interventions should enhance existing therapy practices to facilitate seamless integration into educators’ routines.
5.1.2 Participatory Design for Social Robotics: An Appropriate Answer for Contextual Appropriateness?
Based on the outlined recommendations, we advocate for a participatory design (PD) approach to responsibly develop and deploy social robots in resource-constrained environments. PD, as noted in prior research, offers a safe space for exploration and experimentation before technology deployment in marginalised communities, especially in the Global South [
105]. Additionally, PD has demonstrated effectiveness in HRI, contributing to the creation of robots for depression management and mood stabilisation [
60]. It also plays a significant role in ecosystem mapping for differently-abled populations, supporting democratic and respectful technology development [
69,
84]. Considering the varied mechanisms of PD [
14], our suggestion is anchored in fostering a dynamic power balance between users and designers, encouraging critical dialogue for user empowerment and collective decision-making [
156]. In crafting social robots for environments like India, our proposed PD approach, with a focus on ethnography, must consider the socioeconomic backgrounds and everyday experiences of special educators. Emphasising the importance of acknowledging disparities in opportunities and resource awareness, inspired by Toyama [
165], the design process should incorporate the voices of all educators, including those marginalised within the professional community. A more respectful and collaborative approach could nurture meaningful partnerships and contribute to deploying well-designed social robots for resource-constrained communities in the Global South.
5.2 Beyond Robotic Realities: Preparing the Educators for Robot-Assisted Interventions
All our participants stressed the need to prepare special educators for robot-assisted interventions. In light of the perceived technical complexity of social robots, we were given to understand that their widespread adoption in marginalised communities could be a tough affair without proper training. Researchers in HCI have consistently recognised the crucial influence of
training and support initiatives on the effectiveness of technology interventions [
47,
67]. Typically, these training programs concentrate on instructing users on utilising new technology [
47]. In our case, we turn to Irani et al.’s inspirational work on postcolonial computing [
71] to put forward our recommendation about first identifying the level of digital literacy and understanding of social robots among special educators and then leveraging their willingness to use technological tools for the overarching benefit of the children. Following this, educators would need training to develop technical competence and proficiency in operating social robot systems. Simultaneously, they would need to engage in critical thinking processes to foster a balanced understanding of social robot systems, recognising both their strengths and weaknesses. This would be crucial towards making educators understand their significance in the therapeutic process despite using AI-enabled agents like social robots. It would also help in making them realise how AI would not be able to replace them entirely or not make their roles redundant [
100]. Additionally, educators should be prepared for the risks and potential errors of using social robots in special educational settings. This preparedness could encourage adoption and boost confidence among them.
When addressing the education and training of special educators on assistive robots, it’s crucial to recognise educators’
hesitancy towards adopting new technology, stemming from their comfort with existing tools. Therefore, training efforts should prioritise sensitising educators about the potential benefits of social robots, providing insights into their strengths and weaknesses, and recognising and leveraging their strong commitment to the overarching goal of benefiting children. Additionally, during the training process, educators should be informed about ethical and privacy-preserving practices related to technologies like social robots, requiring programs to navigate diverse cultural perspectives and values within the context of privacy [
105].
Additionally, drawing from the works of Uzorka et al. on professional development [
166], we suggest that by actively involving educators and care workers as
participants in scientific projects encompassing assistive technology, the role of robots as tools for empowerment rather than a burden could be strongly established in their minds. For the effective execution of training and exposure programs, it is imperative for academic institutions, research laboratories, and well-resourced researchers to proactively participate in outreach activities and capacity-building initiatives. This involvement includes collaborative efforts with various organisations such as special education schools, non-governmental organisations dedicated to differently-abled children, and publicly funded schools catering to children with special needs. This collaboration can take the form of workshops and joint seminars. In particular, there should be a concerted effort to encourage young researchers under supervision to take the lead in community-driven endeavours, fostering the dissemination of scientific knowledge across all sections of society.
5.3 On the Future of RAT in India: Unpacking Strategies for the Adoption of Social Robots in Low-Resource Settings
Our final suggestion rests on the future of RAT in low-resource settings by envisioning a pathway for the adoption of SARs over a period of time. To that effect, we feel that there are three important institutions, namely government agencies, civil society organisations and special education schools themselves, that have to contribute and commit in different ways.
As discussed in existing literature, technology interventions from non-domestic sources for accessibility are often
costly due to high procurement expenses, including taxes and import duties [
143]. The United Nations Convention on the Rights of Persons with Disabilities
5 (UN-CRPD) forms a critical foundation for promoting low-cost Assistive Technology (AT) in developing nations by mandating signatory countries to ensure accessible conditions for their citizens. Based on this principle, we, therefore, agree with Pal et al. in suggesting the development of assistive technological interventions to materialise cost-effective solutions for resource-constrained communities [
143,
144].
The Government of India has already implemented schemes such as
Make-in-India6 and
Digital India7, along with grants from the Science and Engineering Research Board
8 and the Department of Science and Technology
9, to promote domestically produced technology products. Under these projects, there have been initiatives that have materialised into the development of indigenous robots like
Vyommitra,
Daksha, and
Manav. A significant development in the area of robotics in India has been the establishment of a
National Robotics Mission10 and the
Indian National Mission on Interdisciplinary Cyber-Physical Systems, 11 specifically with centres for Robotics and Cobotics, emphasising indigenous technology creation and transfer. The proposal outlines a replicable model for other Global South countries, offering strategic support through institutional backing, tax exemptions, and facilitator grants to promote innovation and technology development.
Despite the program’s emphasis on innovation and technology development, there remains a gap in addressing
public awareness about technological advances and
educating individuals on technology building and innovations. To address these gaps, we propose that the
National Education Policy (NEP)12 should prioritise Science, Technology, Engineering, and Mathematics (STEM) education, fostering a skilled workforce for technological advancements and creating an educational environment that encourages students to contribute to progress in diverse technological domains, especially in social robotics. Simultaneously, programs like India’s
National Mental Health Programme 13 that currently lacks avenues for technology inclusion require to be revamped to the integration of technology-enabled mental health interventions by incorporating technology education into their training and awareness programs. By providing comprehensive training programs, educators can overcome apprehensions and misconceptions, fostering a more informed and confident approach to incorporating these technologies into the learning environment.
Our findings further point towards the need to infuse accountability at the institutional level within special education schools and organisations. In this regard, we suggest special education institutions should take charge of the maintenance and preservation of social robots, assuming responsibility for their upkeep and, bearing the costs associated with accidental breakdowns, partnering with civil society organisations. Simultaneously, financially well-off schools can collaborate with civil society organisations to prioritise training and awareness for educators, fostering a collective understanding of social robot usage. We suggest that emphasising institutional accountability and responsible robotics development ensures a sustainable framework for adopting and utilising social robots, empowering special education professionals simultaneously.
We further recommend establishing
appropriate policies and ethical guidelines to regulate robot-assisted interventions for diagnostic and therapeutic purposes. In contrast to the Global North, where guidelines exist for the safe and ethical use of such technologies [
93], countries like India seem to lack such frameworks. While there have been initiatives in framing policies governing AI in healthcare
14, we strongly advocate developing similar frameworks to ensure the safe and responsible use of social robots in the Global South.
In summary, our multifaceted strategy envisions indigenous development, robust government support, targeted training, affordable pricing models, and collaborative efforts at societal and institutional levels. In materialising them, some of the challenges in the effective and responsible integration of social robots into the clinical settings of marginalised communities like India could be adequately addressed.
5.4 Limitations and Future Works
While our research has provided insights into technology adoption and HRI in the Global South, it is not without its limitations. Primarily influenced by perspectives from professionals in Indian metropolitan cities, our study lacks representation from care workers or special educators in rural and semi-urban regions. This limitation is particularly noteworthy given India’s significant rural population. In future endeavours, we commit to addressing this gap by actively involving participants from non-urban areas.
Furthermore, our study provides insights from 25 special education professionals only, who were initiated for recruitment immediately after the pandemic. Initial hesitancy arose due to perceived time constraints, with educators expressing reservations influenced by past mistreatment by researchers. We anticipate that our set of recommendations will guide researchers to be more considerate of special educators and other respondents, fostering greater participation in future studies.
In addition, our current study centres on the viewpoints of special education professionals, recognising the necessity of parental consent for interventions like social robots in India. While valuable, we acknowledge the need to broaden our scope in future studies to include parents and other stakeholders. We encourage researchers in the Global South to adopt a comprehensive approach, involving children, parents, and the larger community in their investigations. Such inclusivity is crucial, especially when the values of researchers, special educators, and communities may diverge at times, as seen in safeguarding personal health data privacy [
105].
The integration of social robots in healthcare raises ethical concerns and is currently being discussed, particularly within the HRI community. In low-resource settings like India, there’s a notable absence of regulatory requirements for AI systems. As social robots address societal challenges, especially in healthcare in resource-constrained settings, there’s an urgent need for regulatory frameworks. These should prioritise ethics, safety, and privacy, emphasising diverse values within a particular context. Our upcoming research aims to explore the ethical dimensions and tensions in real-world deployment, validating findings in healthcare facilities. A long-term study in clinics will further assess the effectiveness of recommendations, focusing on patient care and ethical considerations.
