There is evidence that gender sets up expectations that have an impact on user experiences with the agent. The objective of this paper was to explore gender affordances of conversational agents. Our examination takes a holistic approach to the analysis of the application of gender stereotypes to nine chatterbots: six embodied (three male and three female), two disembodied (male and female), and a robot embodiment. Building on social psychology research, our objective was to test the persistence of gender stereotypes in the selection of conversation topics and in the elicitation of disinhibition and verbal abuse. Our study is based on quantitative textual analysis of interaction logs. A dictionary of English sexual slang and derogatory terms was developed for this study. Results show that gender stereotypes tend to affect interaction more at the relational (style) level then at the referential (content) level of conversation. People attribute negative stereotypes to female-presenting chatterbots more often than they do to male-presenting chatterbots, and female-presenting chatterbots are more often the objects of implicit and explicit sexual attention and swear words. We conclude by calling for a more informed analysis of user interactions that considers the full range of user interactions.

We start by describing a case study on the design and use of a smartphone application for the canteen services of a local university; based on this, we propose what we call the hourglass approach to support participatory design and development in Information Technology. The hourglass is defined by the intersection of two co-evolving dimensions of infrastructuring: the social and the technical ones. Different subsets of the community, characterized by the increasing involvement of self-selected volunteers, position themselves along the two axes and have different roles in the design and use of the generated artefact. We conclude by discussing how this approach can help addressing some of the current challenges (i.e. scale, milieu and responsibilities) of social innovation in Information Technology.

The analysis is based on both transcripts of the interaction and user comments collected in a focus group. Results suggest that the introduction of explicit anthropomorphism in Human-Computer Interaction (HCI) is a complex phenomenon, which could generate strong negative reactions from the part of the user.

Alternatively, a participatory design approach was applied to the generation of ideas for new product opportunities in the active wheelchair user market and to the initial stages of a European project aiming to develop an intelligent mobility aid for older people. Users were acutely aware of problems with existing technology or designs, and including them during early discussion and design stages was shown to facilitate new concept generation.
This highly transferable approach enhances the user experience and commercial potential of products and services, and will be of interest to product manufacturers, designers, and researchers, alike.

The Social Force Model (SFM) is such a model, having parameters that control both deterministic and stochastic elements. We have constructed an efficient motion planning algorithm by embedding the SFM in a control loop that determines higher level objectives and reacts to environmental changes. Low level predictive modelling is provided by the SFM fed by sensors; high level logic is provided by statistical model checking. To parametrise and improve our motion planning algorithm, we have conducted experiments to consider typical human interactions in crowded environments. We have identified a number of behavioural patterns which may be explicitly incorporated in the SFM to enhance its predictive power. In this paper we describe the results of these experiments and how we parametrise the SFM.

The method comprises obtaining details of a user's target (such as a particular desired purchase) together with a visual representation of that target whenever the user wishes to conduct a financial transaction with the SST. The financial status of the user, including a savings regime or budget, is obtained and compared with the target to determine a proximity to the target. When the user ...

This paper focuses on User Engagement (UE), a restricted explanation of UX that concentrates on judgement of product quality during interaction. It presents a model to explain how users' judge quality according to criteria such as aesthetics, usability and engagement.

It’s one of the oldest pleasures there is. Something moves, boo, you wing it. Beast, bird or human, the thing to do is to knock it down. It's primal, Davy. It's basic to the origin of the species.” -Don DeLillo, Americana

The framework is discussed through the case study of a mobility application developed within a wider project of digital commons design. We contrast a Smart City approach and a urban computing one, and we argue that the latter is more fruitful in the long run, since it entails elements for the establishment of forms of recursive engagement of users, who co-produce digital commons together with technology designers as a response to their matters of concern. Applying our framework to the design of urban technologies, we conclude that design should support collaborative practices starting from the articulation of matters of concern to designing in a participatory way.
