HandSight: A Touch-Based Wearable System to Increase Information Accessibility for People With Visual Impairments

HandSight augments the sense of touch in order to help people with visual impairments more easily access the physical and digital information they encounter throughout their daily lives. It is still in an early stage, but the envisioned system will consist of tiny CMOS cameras and micro-haptic actuators mounted on one or more fingers, computer vision and machine learning algorithms to support fingertip-based sensing, and a smartwatch for processing, power, and speech output. Potential use-cases include reading or exploring the layout of a newspaper article or other physical document, identifying colors and visual textures when getting dressed in the morning, or even performing taps or gestures on the palm or other surfaces to control a mobile phone.
