Growing up with blindness or low vision can be difficult for kids, not just because they can’t read the same books or play the same games as their sighted peers; Vision is also a big part of social interaction and conversation. This Microsoft research project uses augmented reality to help kids with vision impairment “see” the people they’re talking with.

The challenge people with vision impairment encounter is, of course, that they can’t see the other people around them. This can prevent them from detecting and using many of the nonverbal cues sighted people use in conversation, especially if those behaviors aren’t learned at an early age.
