Research Abstract

The population of the blind is about 330,000 in our country and the rate of the aged rises every year. Recently. the number of adventitious blind is increased by traffic accidents and diseases such as cataract and diabetic retinopathy. It is difficult for the aged acquired blind to learn Braille. However, they still want to read printed type, write letters and draw pictures as sighted people do.
When a sighted person writes characters and draws figures, he unconsciously uses the visual feedback. If he lost feedback, he could not write characters properly formed in the correct position on the paper. Accordingly, the visually handicapped persons may be able to write characters by using a sound feedback of information which helps them to write correctly.
In this research, we try to improve our support system which helps an acquired blind to write characters and to draw figeres by using a new spatial auditory display. Handwriting patterns can be expressed on a virtural auditory screen perceived with headphones Listening. In this system, a pen position on the tablet is converted into that of a point sound image which is synthesized by the factor of sound localization. A new virtual auditory screen is designed by the experimental factors of sound image location. We also examine the possibility of handwriting and drawing by using a new support system. We also examine the possibility of handwriting and drawing by using a new support system. As the experimental results. It is shown that this systems is helpful when the adventitious blind write characters and draw figures.
