Abstract
Research and development of Assistive Technology (AT) for blind people is primarily focused on assisting mobility and improving access to information. Some particularly useful devices for aiding access to information and communication are DAISY players used with talking books, screen readers for reading screens, video magnifiers to aid low vision, Braille displays, and Braille PDAs. These essential devices have been successfully commercialized and have assisted many visually impaired people. Assistive technology devices for visually impaired people are called sensory substitution devices, because these devices substitute tactile or auditory functions for visual functions. The tactile interfaces of sensory substitution devices such as Braille displays and Braille PDAs have a bimorph type of piezoelectric actuator that forms a Braille (pin) of the Braille cells by moving up and down. KGS Corporation of Japan has more than 80% share of the worldwide market for these Braille cell actuators. Commercializing it for the first time in the world. This paper reviews the various endeavors in Japan in the research and development of tactile displays, such as Braille displays and Braille PDAs. Furthermore, it discusses sensory substitution devices that use tactile displays, focusing especially on the rotating Braille display we have developed.
