G. Melfi, L. Schölch, T. Schwarz, K. Müller, R. Stiefelhagen, Audio-Tactile Reader (ATR): Interaction Concepts for Students with Blindness to Explore Digital STEM Documents on a 2D Haptic Device, Proceedings of IEEE Haptics Symposium 2022
Abstract: 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 twodimensional tactile display. In a study, we tested our ATR system with four blind participants. The results show that the information could be extracted correctly. The two main interaction methods, zooming and element filtering, were rated as very useful by the participants. The system was compared to tactile paper graphics commonly used by participants as a baseline. The comparison showed that the ATR system is competitive with tactile paper graphics, and the majority of the users preferred ATR.
