Sensory Substitution Device Tingles Back Of Your Hand
1 min read
Summary
The Chicago University “Seeing with the Hands” project is developing technology to help blind people experience what they cannot see through sensors on the back of the hand.
It uses a wrist-mounted camera and an 8x8 array of pixels on the hand to send signals to the skin to provide an alternative to sight.
The project is one of several that aim to use different sensory substitution devices to help those with impairments experience aspects of the world in different ways, for example, by converting sound to touch.
Another maker suggests developing a circular visualisation of 3D audio, like a 360-degree spectrogram, which could work with AR glasses to help the hearing-impaired experience sound.
