• Accessible spaces: navigating through a marked environment with a camera phone

  Kee-Yip Chan, Roberto Manduchi, James Coughlan · 2007 · Proceedings of the 9th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '07)

  This short Assets '07 demonstration paper from UC Santa Cruz and the Smith-Kettlewell Eye Research Institute describes a camera-phone-based wayfinding system for blind travellers. The core idea is to deploy small, cheap, pie-shaped colour markers in an environment — on walls,…
