A tactile display system in the use of a PC for individuals who are deaf-blind

Abstract

A purpose of this study is to develop a sensory aid system for totally deaf-blind persons who are not Braille users. We developed a tactile display system and also designed special font style for the display. In this paper, we evaluated the font style as well as the tactile display from a viewpoint of the character identification test. It is found that the percent correct answer was more than 90% when ninety-three characters were presented onto the display. This result suggests that it is enough to enable the deaf-blind to understand the presented characters using our tactile display system instead of the Braille display. © Springer-Verlag 2004.
