Audio-Tactile Reader (ATR): Interaction Concepts for Students with Blindness to Explore Digital STEM Documents on a 2D Haptic Device

Infographics are a big challenge for people with visual impairments. We therefore investigate in our work how access to graphical STEM content can be improved for blind university students using specific interaction concepts on a two-dimensional tactile display. In a study, we tested our ATR system with four blind participants. The results show that the information could be extracted correctly. Th...
