ABSTRACT
We present a study focusing on the usability of a wayfinding and localization system for persons with visual impairment. This system uses special color markers, placed at key locations in the environment, that can be detected by a regular camera phone. Three blind participants tested the system in various indoor locations and under different system settings. Quantitative performance results are reported.

Computer vision-based clear path guidance for blind wheelchair users
Assets '08: Proceedings of the 10th international ACM SIGACCESS conference on Computers and accessibilityWe describe a system for guiding blind and visually impaired wheelchair users along a clear path that uses computer vision to sense the presence of obstacles or other terrain features and warn the user accordingly. Since multiple terrain features can be ...
