Interaction with colored graphical representations on braille devices

Abstract

For several years there has been the wish to make colors accessible to blind people. Colors are all around us and sighted people often talk about colors as it is a simple means of distinguishing objects. They are used in educational materials to ease perception, support comprehension, and focus on different aspects. In this paper we present a new color code for viewing and editing colored graphics on Braille devices and report on our experiences with presen ting graphics on Braille devices and our ongoing work on exploration strategies. © 2009 Springer Berlin Heidelberg.
