Abstract
t One important issue in developing assistive navigation systems for
people with disability is the accuracy and relevancy of the systems’ knowledge
bases from the perspective of these special user groups. The theory of affordances
coupled with computer-based simulation offers a solution for automating the
extraction of the relevant information from readily available sources—architectural
floor plans. Simulation of movement in a wheelchair can be used to compute the
accessible space of an indoor environment by comparing the degree of match
between geometrical demands of navigation and the relevant physical properties of
the environment. We also investigate what constitutes the right level of representation
of the environment and adopt the grid graph model as suitable both for
accessibility computation and for deriving higher-level networks of places and their
connections that facilitate orientation and user-system interaction.
