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.

Morgan, Maggie, Martin, Chris, McGee-Lennon, Marilyn, Clark, Julia, Hine, Nicolas A., Wolters, Maria and Arnott, John (2008): Requirements gathering with diverse user groups and stakeholders. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 2597-2600.
An interactive theatre piece has been designed to facilitate requirements gathering with a diverse range of user groups and stakeholders within the conceptual stage of telecare equipment for the home environment. The piece has been devised and produced by theatre professionals in consultation with computer engineers as part of a major research programme developing computer systems to support older and disabled people. By the interaction of a researcher, two actors and some video-clips, this piece demonstrates: a) the vital importance of all stakeholders being properly consulted and for them to inter-communicate well, and b) the role of theatre as a tool in this process. The rationale and methodology of this technique is discussed in an interactive session with the audience.

Prior, Suzanne, Arnott, John and Dickinson, Anna (2008): Interface metaphor design and instant messaging for older adults. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 3747-3752.
Instant Messaging is currently not widely adopted among older computer users. An investigation has therefore been conducted into the use of Instant Messaging by older computer novices, with particular emphasis on the use of an alternative metaphor in the user interface to try to produce a more usable and acceptable solution for older adults. Two messenger interfaces (a traditional one and an experimental alternative) were designed for the study and compared in use by older computer novices, through measurement and participant interview. Results showed that the alternative metaphor interface performed better overall and that the majority of the participants preferred it for future use.

Bhachu, Amritpal Singh, Hine, Nicolas and Arnott, John (2008): Technology devices for older adults to aid self management of chronic health conditions. In: Tenth Annual ACM SIGACCESS Conference on Assistive Technologies 2008. pp. 59-66.
The overall purpose of this study is the enhancement of devices and visualisations used by older adults as part of a telecare system for the self-management of health conditions. The opinions and feelings towards devices that could be used as part of a telecare system were gathered from a range of older people. This was done through the use of technology evaluation workshops, and the subsequent analysis of the collected data using grounded theory and thematic coding methodologies. Presenting healthcare data to an elderly person with chronic health issues, may be an appropriate way to help that person to better manage their condition, if the data can be understood.

Dickinson, A., Arnott, John and Prior, S. (2007): Methods for human-computer interaction research with older people. In Behaviour and Information Technology, 26 (4) pp. 343-352.
Experimental research in human-computer interaction commonly uses participant groups that are unrepresentative of demographic realities, being young, technically knowledgeable and highly educated. One way of reflecting society more accurately in research is to include older adults in research groups, but the elicitation of high-quality data from these participants requires alterations in research methods and organization. In the present paper, methodological and organizational experiences from a range of research studies with older participants are reported. It concludes with a list of guidelines for maximizing the research outcomes of working with older adults.

McKinlay, Andy, Procter, Rob, Masting, Oliver, Woodburn, Robin and Arnott, John (1994): Studies of Turn-Taking in Computer-Mediated Communication. In Interacting with Computers, 6 (2) pp. 151-171.
Groupware is designed to provide opportunities for physically dispersed computer users to co-operate in a manner akin to a face-to-face meeting. Little is understood, however, of the factors that might influence its success. One possible factor is 'floor control', or turn-taking, which is an important feature of face-to-face meetings. The paper describes experiments designed to examine the importance of turn-taking in computer-mediated communications, in comparison with face-to-face conversations, and considers means whereby turn-taking behaviour, and hence the effectiveness of groupware, can be improved.

Proceedings of the Eighth Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers VIII August 7-10, 1993, Loughborough University, UK. pp. 383-394.
Synchronous computer-supported cooperative work (CSCW) tools are intended to provide opportunities for remotely located groups to work together in a manner akin to groups meeting face-to-face. Little is understood, however, of what may influence the effectiveness of group work performed under these circumstances. One likely factor is the way in which 'floor control', or turn management is supported, and its impact on group coordination. This paper describes an experiment designed to examine the impact of different turn management protocols on the performance of groups using a CSCW tool. The results are compared with the performance of a group working face-to-face. Finally, the implications for coordination in synchronous CSCW are discussed.

An automatic transcription system for machine shorthand takes the output from a shorthand machine, and converts it into a Draft Transcript. This draft transcript needs to be edited to perfection using word processing techniques. A suite of programmes has been written which takes advantage of the particular characteristics of Palantype transcripts to provide a very efficient editing environment. The editor adapts to the user in a way which improves his efficiency without an overhead of the necessity to learn complex control structures. Some of these facilities are also appropriate to a standard word processing environment.
