Study of Brailled-information transmission methods using passive tactility

Abstract

We have studied methods for transferring electronic character information into Braille so that blind people would be able to access it more easily. We considered two methods ; one presenting a 6-point Braille character by separating the 6 point for 6 digits (6-digits/character method) and another showing one character on one Braille display (one-digit/character method). In pursuit of an optimal display method, both methods were evaluated for ease with which displayed characters could be understood, and then the results were compared. In the result, the 6-digit/character method provided high recognition percentages even for those people with acquired loss of sight and those with normal sight. In this report, we would like to discuss the new passive tactility Braille transmission method and our assessment results thereof.
