Could you please send the following call for papers out on the chi.announcements list? Apologies if you have previously received this request in an unusable form from another source (as I suspect you have - Mac MS Word 5.1 ring any bells?). :^( Thank you in anticipation. Eamonn O'Neill Human-Computer Interaction Lab Department of Computer Science Queen Mary & Westfield College University of London Mile End Road London E1 4NS UK ------------------------------------------------------------- Call for Papers HUMAN-COMPUTER INTERACTION A Journal of Theoretical, Empirical and Methodological Issues of User Science and of System Design Special Issue on Representations in Interactive Systems Development Various representations serve diverse purposes throughout interactive systems development. Representations may be used to support processes such as analysis of users' work and environment, envisioning and implementing new work situations and technology and evaluation of usability, work performance and quality. In playing a part in such processes, a representation may provide, for example, an embodiment or model of the object of a particular development activity. It may provide an historical record of the development process. It may serve as a channel of communication within or between groups of stakeholders in the development process. Representations may take many different forms. Dimensions along which types of representations may be considered include formal to informal, general to concrete, exclusive to participative, tool-based to ad hoc, graphical to propositional. Questions of interest include: which processes and activities within systems development may benefit from or require particular representations? Which form of representation is most appropriate to meet which needs? What benefits has one form of representation over another, in what circumstances? Which properties of representations support particular processes, roles and activities? Who needs to be able to understand and work with a given representation? What tools and environment must be provided to support construction and use of a particular representation? Papers should present the authors' work and ideas on representations and their uses within systems development, addressing the above or related questions. Five clear copies of a submission should be sent to Patricia Sheehan, HCI Administrative Editor, Xerox Palo Alto Research Center, 3333 Coyote Hill Road, Palo Alto, CA 94303, USA. A note should be included that the submission is for the special issue. For further information see Information for Authors in the journal or at http://www.parc.xerox.com/HCI. Deadline for submissions is 19 September 1997. Guest editors for this special issue are Peter Johnson, Hilary Johnson and Eamonn O'Neill of Queen Mary and Westfield College, University of London, UK.
