Helping the Blind Understand Facial Expressions

There is a lot that the blind can tell about how someone is feeling based on the tone of their voice, but sometimes it's not enough. This problem has led to researchers creating a device that will allow the blind to see facial expressions of the people their interacting with through vibrations felt on their skin. The prototype device uses a web camera and a tactile display. In order to use the device, the blind first practice learning what the vibrations mean by putting the camera on themselves and making different facial expressions.

I can see multiple uses for this device. Not only will the blind be able to better understand the emotions of the people they interact with, but they can also practice making facial expressions. One of the most challenging things for the blind to learn is non-verbal communication, especially if they've never been able to see. Parents and teachers can try to teach these skills by using verbal descriptions, but seeing is the best way. Since the vibrations will be linked to facial expressions the blind person has made, its possible that this device could help broaden expressions that the blind use.

I know for me, seeing someone smile is one of the things I miss the most. Using a device like this wouldn't allow me to truly see that the person is smiling, but at least I would know when they are.

This article will tell you more about the device.
