IIT-Delhi, Indiana University collaborate to help visually impaired
New Delhi: A three-year collaborative research by IIT-Delhi and Indiana University in the US has led the team to new technologies and cognitive strategies that could improve the lives of the blind and visually impaired (BVI).
The collaboration has resulted in research for the development of a novel new design approach to tactile graphics. "Tactile graphics" -- sometimes called as raised line drawings -- are two-dimensional images composed of linear and textured design elements raised very slightly above a flat surrounding surface.
