AI-powered smart glasses for the blind can read and recognize faces

'Everyone is entitled to live in a world without boundaries,' says Karthik Kannan, co-founder of a company called Envision that designs smart glasses for blind and visually impaired users. 'Our mission is to improve the lives of the world's two billion people who are blind or visually impaired by providing them with life-changing assistive technologies, products and services.' Developed on the Enterprise Edition of Google Glass, the smart glasses harness the power of artificial intelligence to extract different kinds of information from images then speak it back to users in over 60 different languages. With its 8MP camera, the glasses can scan digital and handwritten text from any surface such as books, letters or labels and turn it into speech. The device can also give detailed descriptions of outdoor scenes and make private and secure video calls to trusted users.
