Abstract

This paper describes our experiences with developing cost-effective assistive technologies for the visually impaired, with a focus on using commercial off-the-shelf technologies as much as possible. Trinetra involves three specific technologies--the grocery shopping assistant, the currency identifier and the transportation assistant--all supported on standard mobile phones with text-to-speech, commonly used by the visually impaired.
