Abstract

A hand-held step-scanning device with interactive media controls for reading by the blind is developed. It uses an array of identical imaging modules with close focus lenses, all fitted in a chamber for convenient handling to suit panoramic imaging of a book or document. The step-scanning technique works in a language independent manner by, permitting continuity of multiple image-snaps with a minimum necessary step-overlap by automatic removal to provide seamless output. The continuity of scanning is achieved evolving two techniques for removing the overlapping using image or text based pattern searching. The results indicate that the device is suitable for reading by blind by integrating text-to-speech/Braille.
