Microsoft CEO Satya Nadella introduces the Seeing AI prototype along with software engineer Saqib Shaikh at the Microsoft Build Developer Conference. Shaikh, who lost his sight when he was seven, helped develop the project, which uses computer vision and natural language processing to describe a person’s surroundings, read text, answer questions and even identify emotions on people’s faces. To get this technology into the hands of as many people as possible, this research project has evolved to be a free smartphone app, released in 2017.
