This study is intended to develop the learning support system for people with acquired visual disabilities. Our investigation results related to learning tools show that the use of Braille and PCs has decreased in the class of special support education. From previous studies, a blind novice user with acquired blindness is able to input Japanese characters directly instead of a keyboard without well training by using gPenTalkerh. In this paper, we additionally proposed gTouchTalkerh, a high-speed text-reading application for the visually impaired and conducted an evaluation experiment for the visually impaired using the prototype developed. In the evaluation experiment, college of technology students experienced visual impairment by performing the same task as the visually impaired while blindfolded. We confirmed the effectiveness of the developed gTouch Talkerh for both the visually impaired group and the blindfolded group of technical college students based on the experimental results.
