Pieces of a larger puzzle: a model for understanding a human- computer interaction system for people with special needs

Resumo

The study of scenarios in which computer based technology and people with special needs play a leading role are confronted, at the vety beginning, with the sense that the effort being approached can be called anything but easy. This adjective presents itself, however, as the main force that drives our work when witting this paper. Our intentions when writing this document are centered on the will to help understand what sort of variables may be associated with this' sort of scenarios, their differentiating aspects and some of the existing solutions which may be used in order to optimize them. Our finalgoal with this paper is to contribute, if even in a symbolic way, to the better comprehension of the pieces, which make up the larger puzzle.
