Description
Braille is one of the most popular visual substitution techniques for the blind to get information. Recently it is becoming a problem that many blind people cannot distinguish Braille. This problem is caused by the small size of the dots therefore, it is difficult especially for beginners to read them. The characteristics of embossed dots that consist of Braille are different from each printer, and it has been known that those characteristics affect the legibility. In this study, for the purpose of defining various patterns of Braille on a sensory level, we examine three factors; the influence of the cross section shapes, height of the dots, and the distance between dots. The participants of this experiment are beginning Braille readers with normal vision. They were given discrimination tasks of Braille-like patterns defined by the combination of three factors mentioned previously. The results show that the effects of the height of the dots and the distance between the dots were different among the shape of cross section, so distinguishability is influenced by interaction of each other, providing helpful data for legible Braille pattern.
