Development of an Object-Oriented Graphic Description Language to Enable Precise Drawing for Blind People

Abstract

Drawing systems for blind people have been developed because it is difficult for them to draw without assistance. Some system has been developed from previous research that enable them to draw using pens and gestures. However, it is difficult for those systems to draw precise figures because they cannot specify detail coordinates when drawing. In addition, some blind people use existing graphic description languages to create precise figures. However, it is a burdensome task for them to think about the drawing process. Based on this background, we are developing an object-oriented graphic description language that enables precise drawing figures and is accessible for blind people. In this paper, we describe the graphic description language we have developed so far.
