Martin, Christopher, Ball, Leslie, Archibald, Jacqueline and Carson, Lloyd (2012): Towards the improvement of self-service systems via emotional virtual agents. In: Proceedings of the HCI12 Conference on People and Computers XXVI 2012. pp. 351-356.

“Affective computing and emotional agents have been found to have a positive effect on human-computer interactions. In order to develop an acceptable emotional agent for use in a self-service interaction, two stages of research were identified and carried out; the first to determine which facial expressions are present in such an interaction and the second to determine which emotional agent behaviours are perceived as appropriate during a problematic self-service shopping task. In the first stage, facial expressions associated with negative affect were found to occur during self-service shopping interactions, indicating that facial expression detection is suitable for detecting negative affective states during self-service interactions. In the second stage, user perceptions of the emotional facial expressions displayed by an emotional agent during a problematic self-service interaction were gathered. Overall, the expression of disgust was found to be perceived as inappropriate while emotionally neutral behaviour was perceived as appropriate, however gender differences suggested that females perceived surprise as inappropriate. Results suggest that agents should change their behaviour and appearance based on user characteristics such as gender.”

Gibson, Lorna, Arnott, John, Moncur, Wendy, Martin, Christopher, Forbes, Paula and Bhachu, Amritpal S. (2010): Designing social networking sites for older adults. In: Proceedings of the HCI10 Conference on People and Computers XXIV 2010. pp. 186-194.

“The importance of older adults' social networks in providing practical, emotional and informational support is well documented. In this paper, we reflect on the personal social networks of older adults, and the shortcomings of existing online Social Networking Sites (SNSs) in supporting their needs. We report findings from ethnographic interviews, focus groups and hands-on demonstrations with older adults, where we find key themes affecting adoption of SNSs. We then consider design aspects that should be taken into account for future SNSs, if they are to meet the preferences of older users.”
