do multi-touch screens help visually impaired people to recognize graphics
This paper introduces our research project for developing a novel graphic representation method with touch and sound as the universal designed touch-screen interface for visually impaired people to understand graphical information. Our previous works on single-touch screens clarified the problems about the low recognition rate of curves. To solve this, an improved graphical representation interface for multi-touch screens were implemented and evaluated.
