Recently, environment that visually impaired persons are capable of getting electric information is being developed. By using Braille display, visually impaired can get various electrical information on network. Therefore, Braille display rapidly spread in the foreign and domentic country. However, when Braille display is used continually, the base material of Braille display becomes worn. It has been pointed out that Braille readers find it difficult to read Braille on worn base material which their forefingers cannot slide easily. In this study, to reduce this friction, we reinvent a thin low friction film cover on worn base material to reduce friction during Braille reading. And also we carried out a study to investigate influence of base material features of Braille display on Braille reading and the effect of its use. We compared the discriminability of Braille when covering two films with excessive and less kinetic friction on the base material. As the results, subjects could read Braille significantly faster and more correctly when less kinetic friction film (powder compounded film) cover was used on the base material. In short, by use of powder compounded film cover, we found that Braille readers' forefingers can slide easily and discriminability of Braille was improved. From this study, we suggest the covering less friction this film on Braille display with worn base material as method of being able to improve the discriminability of Braille.
