Among the challenges of growing up with a visual impairment is learning and participating in the social and conversational body language used by sighted people. PeopleLens is a research project at Microsoft that helps the user stay aware of the locations and identities of the people around them, promoting richer and more spontaneous interactions.

A sighted person looking around a room can quickly tell who is where, who’s talking to whom and other basic information useful for lots of social cues and behaviors. A blind person, however, may not know who has just entered a room, or whether someone has just looked at them to prompt them to speak. This can lead to isolation and antisocial behaviors, like avoiding groups.
