DESCRIPTION:Thimbleby\, H. (2004). User interface design with matrix algeb
 ra.\nACM Transactions on Computer-Human Interaction (TOCHI) 11(2)\, \n181-
 236.\n\nAvailable online at: http://tinyurl.com/agbpj\n\nOriginal abstract
 :\nIt is usually very hard\, both for designers and users\, to reason\nrel
 iably about user interfaces. This article shows that 'push\nbutton' and 'p
 oint and click' user interfaces are algebraic\nstructures. Users effective
 ly do algebra when they interact\, and\ntherefore we can be precise about 
 some important design issues\nand issues of usability. Matrix algebra\, in
  particular\, is useful\nfor explicit calculation and for proof of various
  user interface\nproperties.With matrix algebra\, we are able to undertake
  with\nease unusally thorough reviews of real user interfaces: this\nartic
 le examines a mobile phone\, a handheld calculator and a\ndigital multimet
 er as case studies\, and draws general conclusions\nabout the approach and
  its relevance to design. \n\nRubric for the reading group: \nEveryone att
 ending is expected to read the paper in advance. Please bring a copy with 
 you\, preferably annotated with interesting reflections. The format of dis
 cussion will be a brief invited introduction/critique by two members of th
 e group\, followed by general discussion and informal mixing.
