Haptic Feedback Wearables Help Blind People See

The goggles are outfitted with dual infrared cameras that create a 3D stereoscopic image of the area in front of the wearer. The visual data is sent to a small computer that translates it to haptic data and then sends it to the sleeve. The interior of the sleeve contains a 5x5 array of pads that press against the forearm and vibrate to communicate the visual data. The system doesn’t use the wearer’s hands or ears, leaving them available to also assist in navigation.
