Simulating emotional reactions in medical dramas

Presenting information on emotionally charged topics is a delicate task: if bare facts alone are conveyed, there is a risk of boring the audience, or coming across as cold and unfeeling; on the other hand, emotional presentation can be appropriate when carefully handled, but when overdone or mishandled risks being perceived as patronising or in poor taste. When Natural Language Generation (NLG) systems present emotionally charged information linguistically, by generating scripts for embodied agents, emotional/affective aspects cannot be ignored. It is important to ensure that viewers consider the presentation appropriate and sympathetic. We are investigating the role of affect in communicating medical information in the context of an NLG system that generates short medical dramas enacted by embodied agents. The dramas have both an informational and an educational purpose in that they help patients review their medical histories whilst receiving explanations of less familiar medical terms and demonstrations of their usage. The dramas are also personalised since they are generated from the patients' own medical records. We view generation of natural/appropriate emotional language as a way to engage and maintain the viewers' attention. For our medical setting, we hypothesize that viewers will consider dialogues more natural when they have an enthusiastic and sympathetic emotional tone. Our second hypothesis proposes that such dialogues are also better for engaging the viewers' attention. As well as describing our NLG system for generating natural emotional language in medical dialogue, we present a pilot study with which we investigate our two hypotheses. Our results were not quite as unequivocal as we had hoped. Firstly, our participants did notice whether a character sympathised with the patient and was enthusiastic. This did not, however, lead them to judge such a character as behaving more naturally or the dialogue as being more engaging. However, when pooling data from our two conditions, dialogues with versus dialogues without emotionally appropriate language use, we discovered, somewhat surprisingly, that participants did consider a dialogue more engaging if they believed that the characters showed sympathy towards the patient, were not cold and unfeeling, and were natural (true for the female agent only)

Modelling 3D product visualisation for online retail atmospherics

Purpose: The Stimulus (S) Organism (O) Responses (R) paradigm has been extensively studied in conventional retailing but has received little attention in the online context. This study aims to investigate the effects of an online retailer atmospheric using three dimensional (3D) product visualisation. Design/methods/approach: We operationalise 3D antecedents, the main online atmospheric cues, as the “stimulus” (S) that attracts consumers’ attention towards the online retailer, authenticity of the 3D, hedonic and utilitarian value as the “organism” (O) part, and consumers’ behavioural intention as the “responses” (R) part. A hypothetical retailer Web site presents a variety of laptops using 3D product visualisations. Findings: The control and animated colours represent the main stimuli (S). Furthermore, 3D authenticity, hedonic and utilitarian values are the main determinants of behavioural intentions. The proposed conceptual model achieves acceptable fit and the hypothesised paths are all valid. Practical implications: Retail website designers can contribute to enhancing consumers’ virtual experience by focusing more on utilitarian and hedonic value. Any 3D flash should include the essential information that consumers seek and consumers should be able to click to any part of the 3D flash to access further information. Originality/values: To the best of the authors’ knowledge, this research is the first in the U.K. that uses a U.K. sample to investigate the effects of using 3D product visualisation on consumers’ perceptions and responses. Our research makes an important contribution to the online atmospheric literature by providing a rich explanation of how authenticity of the 3D virtual models adds more information, fun and enhances consumers’ responses towards the online retailer

Artificial Companions with Personality and Social Role

Subtitle: "Expectations from Users on the Design of Groups of Companions"International audienceRobots and virtual characters are becoming increasingly used in our everyday life. Yet, they are still far from being able to maintain long-term social relationships with users. It also remains unclear what future users will expect from these so-called "artificial companions" in terms of social roles and personality. These questions are of importance because users will be surrounded with multiple artificial companions. These issues of social roles and personality among a group of companions are sledom tackled in user studies. In this paper, we describe a study in which 94 participants reported that social roles and personalities they would expect from groups of companions. We explain how the resulsts give insights for the design of future groups of companions endowed with social intelligence

Designing and Implementing Embodied Agents: Learning from Experience

In this paper, we provide an overview of part of our experience in designing and implementing some of the embodied agents and talking faces that we have used for our research into human computer interaction. We focus on the techniques that were used and evaluate this with respect to the purpose that the agents and faces were to serve and the costs involved in producing and maintaining the software. We discuss the function of this research and development in relation to the educational programme of our graduate students

Emotion in Future Intelligent Machines

Over the past decades, research in cognitive and affective neuroscience has emphasized that emotion is crucial for human intelligence and in fact inseparable from cognition. Concurrently, there has been a significantly growing interest in simulating and modeling emotion in robots and artificial agents. Yet, existing models of emotion and their integration in cognitive architectures remain quite limited and frequently disconnected from neuroscientific evidence. We argue that a stronger integration of emotion in robot models is critical for the design of intelligent machines capable of tackling real world problems. Drawing from current neuroscientific knowledge, we provide a set of guidelines for future research in artificial emotion and intelligent machines more generally

Cohousing IoT:Technology Design for Life In Community

This paper presents a research-through-design project to develop and interpret speculative smart home technologies for cohousing communities—Cohousing IoT. Fieldwork at multiple sites coupled to a constructive design research process led to three prototypes designed for cohousing communities: Cohousing Radio, Physical RSVP, and Participation Scales. These were brought back to the communities that inspired them as a form of evaluation, but also to generate new understandings of designing for cohousing. In discussing how they understand these prototypes, this paper offers an account of how research though design generates knowledge that is specific to the conditions and issues that matter to communities. This contributes to design research more broadly in two ways. First, it demonstrates how contemporary ideas of smart home technology are or could be made relevant to broader ways of living in the future. Second, it provides an example of how a design research process can serve to uncover community values, issues, and goals

Bringing tabletop technologies to kindergarten children

Taking computer technology away from the desktop and into a more physical, manipulative space, is known that provide many benefits and is generally considered to result in a system that is easier to learn and more natural to use. This paper describes a design solution that allows kindergarten children to take the benefits of the new pedagogical possibilities that tangible interaction and tabletop technologies offer for manipulative learning. After analysis of children's cognitive and psychomotor skills, we have designed and tuned a prototype game that is suitable for children aged 3 to 4 years old. Our prototype uniquely combines low cost tangible interaction and tabletop technology with tutored learning. The design has been based on the observation of children using the technology, letting them freely play with the application during three play sessions. These observational sessions informed the design decisions for the game whilst also confirming the children's enjoyment of the prototype
