Abstract
For example, when sighted scholars study mathematics and physics etcetera, they need to access visual information, e.g., graphs and pictures. Furthermore, sighted people can express their own ideas and opinions visually. On the other hand, blind people can access visual information if it is expressed tactilely, but find it difficult to express their ideas and opinions visually. We are therefore developing a computer-aided system enabling blind people to draw their own figures on their own. This system consists of a matrix braille display to edit computer line drawings. The matrix braille display enables the blind to feel a tactile graphic during editing. After explaining two input methods for elementary plane shapes, we discuss two methods for scrolling tactile graphics to make the matrix braille display large enough to show tactile graphics in sufficient detail. We then show experimental results for using input and scrolling, and conclude with discussion on the usability of input and scrolling.
