Bionic eyeglass: The first prototype A personal navigation device for visually impaired - A review

The first self-contained experimental prototype of a bionic eyeglass is presented in this paper, a device that helps blind and visually impaired people in basic tasks of their everyday life by converting visual information into speech. The indoor and outdoor situations and tasks have been selected by a technical committee consisting of blind and visually impaired persons, considering their most important needs and potential practical benefits that an audio guide can provide. The prototype system uses a cell phone as a frontend and embedded cellular visual computer as a computing device. Typical events have been collected in the blind mobile navigation database to validate the algorithms developed.
