Shortly after the first  Sight Tech Global event, in December last year, Apple and Microsoft announced remarkable new features for mobile phones. Anyone could point the phone camera at a scene and request a “scene description.” In a flash, a cloud-based, computer vision AI determined what was in the scene and a machine-voice read the information. Learning that “a room contains three chairs and a table” might not seem like a big advance for the sighted, but for blind or visually impaired people, the new feature was a notable milestone for accessibility technology: An affordable, portable and nearly universal device could now “see” on behalf of just about anyone.
