Paper Abstract

This paper describes the optical hand-held scanner designed for use as an input device to the Kurzweil reading machine for the blind and visually-impaired. This device has numerous advantages over other scanners, chief among which are its high resolution, one-inch field of view, bidirectional capabilities, and compact block-shape. The device allows the user to scan single sheets as well as bound books and magazines. During its three-year development, the major emphasis has been on refining the design to make the device easy to use. This paper addresses the technical issues associated with the human-factors considerations that led us to this design.
