It's hard to read people's emotions if you're blind. Now the visually impaired can wear a special forearm sleeve that tips them off to people's facial expressions. That device is hooked up to a webcam, whose images are fed into advanced recognition software that can accurately interpret facial expressions. It then translates those interpretations into coded vibrations that are easily sensed.
The software could go beyond helping blind people read emotions — those who suffer from autism could also use a little help in this area. An augmented reality display could let them know if someone is happy, sad, or bored. If this thing got to be accurate enough, it might come in handy reading telltale faces during our weekly poker game.
