From the Braille alphabet to the seeing-eye dog, history is filled with efforts to help the sight-challenged navigate the world. In 2012, NTT Service Evolution Laboratories is working to change the game completely with a revolutionary new product called SightFinder. Its cloud-based image and sound recognition technology, still in the prototype phase, will send visually-impaired pedestrians real-time alerts, warnings, guidance, directions and other useful information directly to their smartphones to help them walk the streets safely. This infographic highlights SiteFinder’s place among other milestones in the history of sight-assistive innovation.
