• Learning and Perceiving Colors Haptically

  Kanav Kahol, Jamieson French, Laura Bratton, Sethuraman Panchanathan · 2006 · Proceedings of the 8th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '06)

  This paper presents a novel system for enabling blind individuals to learn, perceive, and compare colours through haptic (touch-based) feedback. Colour is a purely visual feature that cannot be perceived through auditory or olfactory senses, yet it plays a significant role in…
