Simple Pattern Creation Using a Pen Input Guide and Sound Localization for the Visually Impaired

In this report, we examine whether or not a visually impaired person can make a formal basic figure by himself. The patterns that we treat in this report are restricted to a collection of lines. In order to make formal patterns, we prepared an acrylic pen input guide and put it on a tablet. This guide has a 9 by 9 lattice of holes which correspond to 9 by 9 localized sounds on a 2-dimensional virtual sound screen. Using this guide and a stylus pen, the visually impaired can make a pattern. The input pattern is checked and corrected by hearing the localized sound. Experiments show that the subjects can input simple patterns correctly.
