Abstract

A prototype lunch delivery web system for visually impaired was developed based on the analysis of human (a visually impaired who wants to order a lunch) to human (a sighted person who helps the visually impaired to decide lunch by reading aloud lunch menu) dialog. Based on the analysis, a prototype system was developed, which consists of three steps: 1) rough selection, 2) selection of favorites, and 3) final selection. The evaluation of the prototype system is performed by the visually impaired only with synthesized speech and key-board. The results showed that our system is effective and easy to use.
