ABSTRACT: The Cognitive Dimensions framework is a generalised broad-brush approach to usability evaluation for all types of information artifact, from programming languages through interactive systems to domestic devices. The 13 (or so!) dimensions (e.g. 'viscosity' - resistance to local change) describe the structure of information and the means for manipulating it, but they are not in themselves evaluative; the framework also distinguishes different types of generic activity, each of which makes different cognitive demands, and the evaluation depends on the match between the intended activity or purpose and the profile of dimensions. In many cases a potential redesign, intended to eliminate one type of problem, can introduce different problems, and these cases can be seen as trade-offs between dimensions. Part of the art of design is to locate the right trade-off. Although very informal, the framework has been found useful in several different projects. It also has promise of interfacing successfully with organisational and sociological analyses. ********************************************************************** THE IMPERIAL COLLGE HCI SEMINARS: The Intelligent & Interactive Systems Group at Imperial College is planning to host a series of HCI seminars during this academic year. Anybody who is interested in the future of HCI research is cordially invited to attend these seminars, which, we hope, will provide a meeting place for the HCI community in the London area and provide food for thought and discussion through the presentation of groundbreaking research by an invited speaker. *********************************************************************** ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~ To receive HCI news, send the message: ~~ ~~ "JOIN BCS-HCI your_firstname your_lastname" ~~ ~~ to [log in to unmask] ~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~ Newsarchives: ~~ ~~ http://www.mailbase.ac.uk/lists/bcs-hci/ ~~ ~~ archive.html ~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~ To join the British HCI Group, contact ~~ ~~ [log in to unmask] ~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
