Multimedia HCI Design

The  aim  of  this  study  is  to  explore  how  bringing  art  to  life  using  Augmented  Reality  (AR)  technology  can affect  viewer  engagement  and  interest  compared  to  the  viewing  of  traditional  static  artwork.  To measure these  properties  this  study  uses  a  combination  of  surveys:  The  User  Engagement  Scale  (UES)  and  a  slightly modified  version  of  the  Museum  Experience  Scale  (MES).  The  results  from  both  questionnaires  were aggregated to obtain a more accurate measurement of engagement, as the UES questionnaire is specifically focused  on  interactive  systems  while  the  MES  is  focused  on  an  overall  view  of  an  exhibit.  Using  both questionnaires a more accurate measurement of “engagement” can be reached for the purposes of this study.

Audition and vision are the two most common senses used by several types of industries as bridge for interaction with the users. And even when skin is one of the largest organs in human body, the sense of touch remains underutilized.
Several limbs of human body are constantly in touch with technological interfaces, especially the hands, which are mostly employed to grasp devices such as mobile phones or tablets. Nowadays, things like the way your smart phone feels in your hand or the content you are able to reproduce and receive from it makes the combinations of hardware and software matters because those are important considerations when buying a device.
Many of the existing devices' back are flat surfaces, usually unused, which could be improved by adding small actuators that convey an underappreciated but worthy type of information: haptic information.
Furthermore, if the broadcasting haptic contents could be easily transmitted through any communication network such as the Internet, for some scenarios like streaming contents, may help to increase the appeal of such immersing multimedia contents to be experienced through mobile devices.
To tackle the former situations, this project takes advantage of the sense of touch by providing users with synthetized haptic audio visual contents through a modified mobile device that integrate ultrasonic actuators that delivers tactile feedback in user’s hand.

As media usage continues to increase on a global scale, fueled by the proliferation of mobile devices, this facilitates the effortless behavior of mediamultitasking. This paradigm shift in the way in which media is consumed presents fundamental challenges for the domains of Human-Computer Interaction (HCI), education, psychology, and commerce. This technological shift introduces a new dimension that is needed when attempting to understand user interaction related to both the devices themselves andthe digital platforms accessed. This study begins a process of developing an understanding of cross-cultural media multitasking habits through a survey of a large group of experimental participants. In this study, participants from two different countries were surveyed. The countries used in this study were the USA and Portugal. This research provides valuable insights into theincreasingly common phenomenon of media multitasking and the similarities and differences between cultures when users are engaging in this activity. This study contributes to previous research in the realm of media multitasking by expanding on foundational knowledge on a global scale setting the stage for more detailed research on predictors, outcomes, and habits of global media multitasking.

The understanding of characteristics of gestures, such as ergonomic, cognitive and social aspects could potentially contribute to an interface design mediated by hand gestures. In this research, a questionnaire model is implemented to suggest some guidelines about the use and gestures of MYO armband in a map application. The user-feedback and observations found during our testing have led us to offer some practical insights to designers and developers on how the prototype of gesture applications on MYO can be extended.

Online shopping is now considered by many to be the future of commerce. Purchasing a product online does not include any physical interaction with the product, purchasing decisions are mainly based on images or videos of the product and this, in turn, relies on the quality of the information presented. Hence, the experience of the users of e-commerce websites is highly dependent upon the user interface and the interaction of users with the website. According to Statista, in 2018, an estimated 1.8 billion people worldwide purchased goods online. During the same year, global e-retail sales amounted to 2.8 trillion U.S. dollars and projections show a growth of up to 4.8 trillion U.S. dollars by 2021.

The human hand dexterity provides a natural and rich interface for computer interaction. Technologies for tracking hand and finger motion are now accessible and can be used with a minimum computation power for the manipulation of virtual puppets in real-time. However creating an intuitive hand-based motion control interface presents problems such as, mapping the hand to an object that demands more degrees of freedom or to assign gestures that are difficult to memorize or to execute. We propose an ergonomic hand-mapping model for digital puppetry, based on the human hand anatomy and biomechanics, adapting traditional puppetry methods. A cinematic virtual puppetry application was developed supporting distinct interaction styles based on the hand dexterity skills. An experiment using the Leap Motion controller was conducted to evaluate the hand mapping feasibility. The participants considered that the proposed interface provides a good level of directness. Furthermore, a custom interface for smartphones was combined with the application to extend the puppet manipulation and show control operations.

In this paper, we describe an experimental approach to the study of coordinated group activity (ensemble) through the development of a responsive media system and enacted movement-based research. Interested in how ensembles emerge, we take into account the material conditions of phenomena associated with coordination and entrainment. To this end we share about the development of a responsive media system and as well as a series of movement experiments with the system. As a unframing tactic, we suspend ontological assumptions which occlude, mask, or ignore relation and event as emergent and unprestateable. This tactic belies both our observations of event as well as the design of responsive behaviors in the media environment apparatus. Our investigations yielded insights for us about embodied experience with respect to technicity.

This handbook is the result of an exploratory study that tries to connect rhetoric and user experience (UX). Here, the user interface (UI) becomes the middle point through which rhetorical figures can be applied to influence the user experience.

Based on the "Rhetorical Handbook" by Hanno Ehses and Ellen Lupton (1988).

This paper discusses and presents a new prototype design for a smartwatch user interface. The user interface was designed aiming to adhere to some of the main universal design principles and be a more usable design. The prototype user interface was then compared with a Samsung Gear S3 smartwatch user interface. The comparison was done via an experiment and a series of realistic tasks. The aspects being investigated were task times, errors and subjective user satisfaction. The data collected were statistically analysed. The overall results showed that the prototype user interface fostered faster task times, fewer errors and more user satisfaction.

Las metáforas de la interfaz. Interfaz es un vocablo que es susceptible de múltiples interpretaciones. Como término informático, es un dispositivo capaz de asegurar el intercambio de datos entre dos sistemas. A partir de allí, se desarrollan diferentes concepciones. Sin embargo, el concepto posee una historia pre informática que se remonta a las investigaciones científicas en el campo de la hidrostática en el siglo XIX. De acuerdo al diccionario inglés de Oxford (S. XIX) una interfaz es una superficie entre dos porciones de materia o espacio que tienen un límite común. En "La hidrostática" (1882) de Bottomley, se define como una superficie de separación plana o curva entre dos porciones contiguas de la misma sustancia. En los "Anales de la academia de las ciencias de Nueva York" (1964) se describe como una serie de componentes que conecta el ordenador digital y el analógico entre sí, y que controla y convierte los datos. En un artículo de "Computación y humanidades" (1969) se explica que "el profesor L. Delatte … pública … diferentes índices computarizados de textos clásicos utilizando una Selectric Typewriter 'interfazada' con su propio ordenador". la interfaz pasa de ser una membrana entre dos superficies, a ser un dispositivo que garantiza la comunicación entre un sistema informático o entre dos de estos a través de una red de comunicación. Teniendo como características: • Ser un dispositivo hardware material, una especie de puente físico que conecta dos sistemas diferentes. • Existir un intercambio bidireccional de información entre dos sistemas. El diccionario de la computación de Oxford (1983) define la interfaz como: 1. Límite común entre dos sistemas, dispositivos o programas. 2. La conexión de señal y los circuitos de control asociados utilizados para conectar dispositivos. 3. Especificaciones de comunicación entre dos unidades de programa. 4. Dar una interfaz. 5. Interactuar. El "Diccionario de informática y del laboratorio electrónico" (1983) concibe la interfaz como el elemento de separación/conexión entre dos unidades o dispositivos. Normalmente se refiere a las características relativas al adaptador para la conexión de unidades pertenecientes a líneas de producción o estándares diversos. El "Diccionario de tecnologías de la información" (1985) define la interfaz en electrónica como un límite en común entre dos dispositivos o componentes relacionados, proyectados con el objetivo de especificar el tipo y la forma de las señales que pasan entre ellos.

Sebagai suatu lembaga pendidikan yang berkaitan dengan masyarakat secara langsung, perguruan tinggi juga perlu membuat brand bagi lembaganya.

Hasil dari penelitian ini adalah bahwa antarmuka website STMIK Sumedang pada umumnya telah mampu memberikan kemudahan bagi pengunjung namun ada beberapa poin yang perlu ditingkatkan dalam hal kemudahan penggunaan dan keakuratan informasi.

Motion capture-based renderings of dance performance constitute a complex, but highly interesting cultural phenomenon at a time when motion recognition and haptic technology increasingly affect society at large. Applications of digital motion capture technologies that aim to support the analysis and transmission of dance performance can be understood as an alternative way of bringing dance into the ‘orbit of writing’ (Rotman 2008). Despite the growth of these practices and their significance for the contemporary discourse on the transmission of dance knowledge, this phenomenon has not yet been thoroughly investigated from the perspective of dance research and practice. This thesis evaluates implications of contemporary practices of digital dance capture. How is dance conceived of as a type of knowledge that can be transmitted in these practices? How does motion capture invite us to know dance differently? This thesis examines different modes of ‘corporeal computation’ of dance by analyzing different ways of making motion data speak. The notion of ‘the motion capture imaginary’ is introduced as a conceptual framework that interconnects various characteristics associated with ways of seeing and knowing dance in the motion capture setting. Foregrounding the value of dancers’ embodied experiences, the thesis suggests that the pursuit to render motion data into accessible feedback calls for further investigation of topics that are typically part of the tacit knowledge of the dancer, such as the central importance of the breath. The process of making sense of motion data streams thus encourages new investigations of technique and knowledge transmission in performance and presents opportunities to articulate the corporeality of dancers in different ways.

Interactive non-fiction uses the affordances of emerging media to educate and persuade audiences. Practitioners of the form aim to create knowledge, and then to persuade others to act upon this constructed knowledge. However, the historical propensity of practitioners to use emerging media has resulted in uneven access and literacy. Privileged communities and groups have access to the technology and get to tell stories first. Communities without access to these media are slow to gain literacy and are unable to express themselves in an emergent digital culture fully. Compared to their privileged peers, these groups are unable to use the rhetorical affordances of these emerging media for their ends. This inequity puts them at a distinct disadvantage. Community workshops for interactive non-fiction can be established to democratize this didactic use of emerging media. These workshops are both pedagogical and a site for social action. To put this theory into practice, I developed a workshop based on historical cases of practitioners using emerging media to create non-fiction with communities as a form of social action. The emerging media chosen for my workshop was mixed reality. The workshop was part of a devised theater class on the campus of the Georgia Institute of Technology. Students gained media literacy through participating in the development of a mobile app that uses mixed reality, and by using that app to create knowledge about safety on campus through performance activities. The knowledge they created came from the students’ personal stories and documentary material. Combining the workshop tactics and the app, students were able to create rhetorically effective and didactic scenes. The ability to use physical space as a canvas to create a digital-visual-spatial argument about how an event should be represented was impactful. Particularly effective was a shared gaze that enabled all of the users to see and create in a shared mixed reality. Evaluation of the workshop showed that students believed that they were able to create compelling mixed reality scenes about their community through the app and that the scenes they created could encourage social action.

Il documento descrive i metodi utilizzati per migliorare l'usabilità e l'esperienza utente mediante la conoscenza del funzionamento dei processi cognitivi implicati. Un sistema usabile è, nell'ottica della psicologia cognitiva, un sistema che economizza lo sforzo cognitivo. Lo studio della psicologia è quindi di aiuto nel progettare interfacce usabili.

INTRODUCTION
The chapter is founded on the premise that current wearable technology design practices represent a reductionist view of human capacity. The democratization of technology into work, play, home, and mobile social networks in recent years has seen traditional human–computer interaction (HCI) design methodology broadened through the integration of other methodologies and knowledge from the humanities such as social science, anthropology, and ethnography. The field of HCI is inherently interdisciplinary and its history is one of the inevitable disciplinary multiculturalisms spawned by the expansive impact of technological growth.
What questions should we be asking to engage a more critical design perspective? This chapter extends traditional functionalist approaches to design to engage cultural, experience-based, and techno-futurist approaches. Wearable technologies are therefore discussed in terms of their critical, political, ethical, and speculative potential, and case studies are presented to illustrate and exemplify the ideas promulgated.
The chapter is organized into three sections. The first section proposes the role of the designer to be one that includes a cultural approach to designing future scenarios—one that considers ethical and speculative implications of how our embodied materiality is affected by emerging technologies. What is the relationship of the self to the proliferating wearable technologies? How is our sense of self changing as new technologies mediate the space between our experience of self and the world? We develop a methodology that asks designers and technologists to build future scenarios and envision how our embodied materiality is affected by emerging technologies. Using a philosophical framework we explore design and its implications on the relationship of the self to the self and to social relationships. We then investigate how technologies such as Google Glasses and Quantified Self applications inform our relationship to our self and redefine our social interactions.
The second section discusses the self and the social politic of wearable technologies from macro to micro perspectives. Considering wider supply and production chains and regulatory systems whose existence shapes the production and meaning of wearables—both their material form and design, and the movement of gathered data from the body into wider dispersed networks of power. Moving from the micro (technology/body) to the macro (systems of production), we consider where control lies across these networks, at what unit of analysis, and what their impact could be on the wider world as they are dispersed.
The final section adopts a techno futurist approach proposing synaptic sculpture as a process for creative design that engages vibrant materiality and the interconnected body. The section describes the emergence of a new paradigm in terms of our augmented perspective—our perception of scale expanding our awareness and sensitivity across macro- and nanolevels. These new spheres of awareness become our normative environment—ones with an amplified awareness of the instability, fungability, and interconnectedness of things. This perspective promulgates the space of design to be in the interface as mediator of experience, rather than design of objects or products. We propose the need to develop a connoisseur of somesthetic qualities surrounding the design of wearables. This subverts the traditional fashion design methodology away from the trickle-down theory to one that can enhance a relationship between designer and user who can become coproducers and connects materiality to anthropology and the lived experience of the individual.

In this paper, we describe an experimental approach to the study of coordinated group activity (ensemble) through the development of a responsive media system and enacted movement-based research. Interested in how ensembles emerge, we take into account the material conditions of phenomena associated with coordination and entrainment. To this end we share about the development of a responsive media system and as well as a series of movement experiments with the system. As a unframing tactic, we suspend ontological assumptions which occlude, mask, or ignore relation and event as emergent and unprestateable. This tactic belies both our observations of event as well as the design of responsive behaviors in the media environment apparatus. Our investigations yielded insights for us about embodied experience with respect to technicity.

This development aims to create a valid product maze game on Interactive WhiteBoard (IWB) for fine motor learning. Game maze is a game consisting of a path or a collection of roads that branch in order to achieve the goal by finding the right path. IWB use for projection game and place which user can interactive with it. IWB cheaper design by Johnny Chung Lee used for this development. There are ten steps that must be carried out referring to the model of the Borg and Gall, but based on certain considerations are not entirely done. The stages are research and information collecting, planning, preliminary form of product development, preliminary field test, and main product revision. The maze game on IWB has been validated by media experts and fine motor learning experts, with valid results. Nevertheless from the field trials revealed that the ease and smooth use of the tool into a separate note. This is due to infrared light cannot be caught by the sensor because it is blocked by students working on the board so that the interaction between games with IWB is disrupted and there is one child who have difficulty using an infrared pen.

This paper describes the introduction of a new website at TCGplayer, who provide an online store for Magic the Gathering collectible cards. This paper describes an experiment that was undertaken to test a new, responsive design, against the current, non-responsive design. It was predicted that redesigning the shopping cart for a mobile device screen, will result in a higher Perceived Usability (PU), and higher satisfaction, as indexed using the Technology Acceptance Model (TAM).

Progress in image sensors and computation power has fueled studies to improve acquisition, processing, and analysis of 3D streams along with 3D scenes/objects reconstruction. The role of motion compensation/ motion estimation (MCME) in 3D TV from end-to-end user is investigated in this chapter. Motion vectors (MVs) are closely related to the concept of disparities, and they can help improving dynamic scene acquisition, content creation, 2D to 3D conversion, compression coding, decompression/decoding, scene rendering, error concealment, virtual/augmented reality handling, intelligent content retrieval, and displaying. Although there are different 3D shape extraction methods, this chapter focuses mostly on shape-from-motion (SfM) techniques due to their relevance to 3D TV. SfM extraction can restore 3D shape information from a single camera data.

The International Journal of Multimedia & Its Applications (IJMA) is a bi monthly open access peer-reviewed journal that publishes articles which contribute new results in all areas of the Multimedia & its applications. The journal focuses on all technical and practical aspects of Multimedia and its applications. The goal of this journal is to bring together researchers and practitioners from academia and industry to focus on understanding recent developments this arena, and establishing new collaborations in these areas.

This paper details a two-part evaluation of the Apple TV user interface. A Heuristic Evaluation and an evaluation using the seven universal design principles were carried out. The overall results showed that the Apple TV user interface has various failings in the design for users of diverse kinds. Suggestions for ways forward include designers using more rigorously the ISO standards and well established user interface design guidelines.

Recently, museums and historic sites have begun reaching out beyond their traditional audience groups, using more innovative digital display technology to find and attract a new audience. Virtual, mixed, and Augmented Reality (AR) technologies are becoming more ubiquitous in our society and "virtual history" exhibits are starting to be available to the public. There are numerous studies focusing on AR, however a scant amount of research is being done at historical sites. An initial experiment used repeated measures (ANOVA) to compare and rank three different types of AR devices used at a site of cultural heritage. A further experiment was then undertaken to observe participants using two different AR devices with and without sound to determine if which device used or the presence of sound impact the usability of the device, or the user's satisfaction/preference of specific devices. Several surveys, including demographic and usability surveys, were provided in order to collect a range of user data. A two-way repeated measures (ANOVA) were used to analyze the quantitative data gathered. No significant effects were observed based on the quantitative data provided by the surveys, indicating that all devices were equally usable and satisfactory, and that sound did not have a significant impact in this instance. However, the qualitative data indicated that users may prefer using AR technology on a smartphone device and preferred to use this device paired with sound.

This paper documents the initial prototyping of a new digital musical instrument. Specifically, it focuses on design of the interface, and contextualizes the project through some of the existing research in the field of gestural control of new musical instruments. The project began with a concept for a stand-alone hand-held polyphonic synthesizer called the Noisebox (Figure 1). Several key concepts and strategies were explored and implemented during its development, including: analysis and application of gesture in musical performance, choice of sensors and sensor conditioning, appropriate mapping strategies , and evaluation of user experience. The outcome yielded a functional prototype that fulfilled the initial goal of the project to design and build a working instrument from start to finish. The stage documented here represents the first phase of a longer project. Future phases will conduct user tests to measure the success of the instrument based on performer feedback and refine the design through multiple iterations, leading to a finished instrument.

In a contemporary world, people become dependent on electronic devices. Technologies help to clarification and structure life in many ways to meet the need of the children oriented requirements. The children suffering from disabilities (e.g. autism) has desperate needs for elucidation and structures their life. MumIES is a research based system facilitates to support and manage their living. This paper works on MumIES system to evaluate usability of the system in extraordinary environment for extraordinary people. The paper shows from the survey observation users need supporting tools to access the children’s potential and challenges and to give the full support to overcome disabilities. Usability evaluation has been considered one of the key challenges to MumIES system. The paper represents analysis, design of usability studies for the extraordinary user in environment.

Este articulo presenta un nuevo marco de referencia para explorar contenido de patrimonio cultural en la Red a través de objetos físicos, y su investigación se deriva a partir de un nuevo entendimiento interdisciplinario sobre el Patrimonio Cultural en la Red (PCR). Nuevas tecnologías en la Red han mejorado el acceso y la calidad de la información de colecciones digitales, y el uso de, por ejemplo, Linked Data y Datos Ontológicos ha permitido la conexión de metadatos a gran escala que permiten a los usuarios y organizaciones extender la complejidad y alcance de su información. Esta nueva complejidad de información tiene la capacidad de generar nuevas preguntas de investigación acerca de cómo los nuevos usuarios en las Redes Semánticas proceden a explorar y desarrollar preguntas sobre el contenido no solo del patrimonio cultural, sino también sobre todo tipo de información en la Red. A través de las disciplinas de Ciencias de la Información, Human Computer Interaction (HCI) y Pedagogía, entre otras, este estudio se enfoca en la creación y análisis de nuevos métodos dentro de estas disciplinas relacionados con el usuario y la importancia de los sistemas interactivos en la Red.

El propósito de esta investigación es la creación de un marco de referencia, teórico y metodológico novedoso para reducir brechas digitales generacionales y de información, donde se permita a usuarios de diferentes niveles desarrollar y elaborar preguntas complejas en las Redes Semánticas enfocadas en Patrimonio Cultural. Como resultado, este estudio presenta el proceso para resolver preguntas de investigación relacionadas con el acceso de información digital a través del uso de Interfaces Tangibles (Tangible User Interfaces/TUI). El prototipo aquí presentado hace uso de la cognición corpórea (embodied cognition) a través de actividades de naturaleza constructivista en las cuales los usuarios se acercan al PCR llevando a cabo preguntas sobre su contenido mediante la utilización de objetos físicos. La metodología utilizada se deriva de investigación previa donde se establecen diferentes niveles de necesidad de la información como un proceso de Interacción Humana con la Información (Human Information Interaction/HII) y a su vez, este proceso utiliza Diseño Centrado en el Usuario (User Centred Design/UCD). El sistema interactivo creado, permite formular preguntas complejas integrando información proveniente de un vasto grupo de diferentes organizaciones dentro del patrimonio cultural (ej. Museos, bibliotecas, archivos, universidades, etc.). El caso de estudio particular que aquí presentamos, se enfoca en Europeana (uno de los mayores proyectos de integración de información cultural digital en Europa) como proveedor de información. A través de su API (Interfaz de Programación de Aplicaciones), el sistema interactivo transforma los datos digitales en elementos físicos manipulables.

Nowadays, virtual laboratories play a crucial role in e-learning education systems. The use of these types of technologies in engineering education presents new opportunities for instructors and learners alike to obtain tangible results and improve their subject knowledge. These results are reached without the need to face challenges such as a dearth of instruments, time, space, assistance (human resource) and so on. Furthermore, virtual laboratories could overcome obstacles such as unexpected and unsafe results common to real laboratories. This book describes the necessary steps involved in the development and design phases of virtual laboratories. Furthermore, the authors explain how to achieve the desired interfaces by using Human Computer Interaction design standards and Multimedia Learning Principles. The present book will offer valuable guidelines for researchers and students keen on developing virtual laboratories

Automobile manufacturers are constantly trying to keep up with current technology trends and respond to today's societal challenges. Cars have become more than just a means for transportation, they are now a fully embedded technological 'multifunctional living space'. The increased complexity of automotive user interfaces, driven by the need for using consumer electronic devices in cars as well as improving comfort, and the overall user/driver experience, has sparked a range of new research within this field of study. The number of infotainment functions (controlled as tertiary tasks) with which a user can interact while driving has greatly increased, making the primary task of driving even more challenging. In creating a better automotive user experience, automobile manufacturers have unintentionally increased the cognitive load of the driver when they are performing these tertiary tasks. This research study aims to reduce the cognitive load of the driver/user by suggesting novel, simple menu design interfaces, which add design improvements in two function aspects (entertainment and comfort) by implementing visual, hands-free and gestural based interfaces. This research study will add to the body of literature aimed at improving driver safety and driving experience while performing a tertiary task.

We present a suite of approaches to how ensembles of people, technical objects, and processes can co-construct events that make ethico-aesthetic sense to the participants. The intents and techniques range from creative uses of gesture-following, vibro-tactile feedback or whole body interaction in performance, to using wearables, and responsive environments to study the dynamics of rhythm, sense and affect.

The objective of this work is to recognize all the frontal faces of a character in the closed world of a movie or situation comedy, given a small number of query faces. This is challenging because faces in a feature-length film are relatively uncontrolled with a wide variability of scale, pose, illumination, and expressions, and also may be partially occluded. We develop a recognition method based on a cascade of processing steps that normalize for the effects of the changing imaging environment. In particular there are three areas of novelty: (i) we suppress the background surrounding the face, enabling the maximum area of the face to be retained for recognition rather than a subset; (ii) we include a pose refinement step to optimize the registration between the test image and face exemplar; and (iii) we use robust distance to a sub-space to allow for partial occlusion and expression change. The method is applied and evaluated on several feature length films. It is demonstrated that high recall rates (over 92%) can be achieved whilst maintaining good precision (over 93%).

Bringing positive experiences to users is one of the key goals when designing conversational agents (CAs). Yet we still lack an understanding of users' underlying needs to achieve positive experiences and how to support them in design. This research first applies Self-Determination Theory in an interview study to explore how users' needs of competence, autonomy and relatedness could be supported or undermined in CA experiences. Ten guidelines are then derived from the interview findings. The key findings demonstrate that: competence is affected by users' knowledge of the CA capabilities and effectiveness of the conversation; autonomy is influenced by flexibility of the conversation, personalisation of the experiences, and control over user data; regarding relatedness, users still have concerns over integrating social features into CAs. The guidelines recommend how to inform users about the system capabilities, design effective and socially appropriate conversations, and support increased system intelligence, customisation, and data transparency.

I wish to confront the claims made for hypertext systems as vehicles for avant-garde expression--for tactical resistance by artists against cultural forms of domination, and, implicitly, for the "liberation" of the consumers of avant-garde art from those forms of domination. I am moved, in particular, to respond skeptically to the tropes from physics and mathematics used by participants of the discussion list Technoculture (from February through May, 1992) to describe the potential of hypertext to offer resistance and liberation. What follows, then, is a critique of the correspondence, implied by these tropes, between specific laws of physics, associated with the terms geometry, contingency, nodes, entropy, and non-linearity, and any property of hypertext that would validate its use as an avant-garde medium.

Usability is concerned with facilitating successful interaction with products and devices. Providing natural forms of interaction may improve a product’s acceptance and usability. Human gesture is an example of such interaction. A number of research and development projects have investigated ‘gesture control’ for over 30 years. We are now reaching a point in technological development where such products are affordable, and even familiar to use. This raises the question of whether we can now benefit from gesture-controlled devices to help us in other scenarios. This paper presents such a gesturecontrolled system, and describes a usability study and numerical analysis, which has evaluated a range of design alternatives. The analysis also represents predictive and quantitative HCI.
