- Wearable for Visually-Impaired – MIT CSAIL researchers developed wearable system able to provide navigation assistance to visually-impaired people using proprietary algorithm and 3D camera, worn in pouch hung around neck
- Two Operating Modes – Can be used for finding chair or table as well as navigating surroundings
- System Specifications – Equipped with 3D camera, processing unit, sensor belt with five vibrating motors, and reconfigurable Braille interface that gives users more data about environment
- How It Works – Algorithm finds surfaces or obstructions by processing images from 3D camera, providing navigation instructions or alerting users if they come close to objects through vibrations
- Test Results – Usability studies found chair-finding system increased accuracy of avoiding contact with objects other than sought chair by 80%, while navigation system reduced number of cane collision with people in a hallway by 86%
