HandSight is a prototype glove to aid the blind. It can sense the lightness or darkness of a surface with tactile feedback from a vibration motor for each individual finger. It can also sense distance from physical objects or obstructions and indicate direction and distance with the same vibration feedback. It supports additional modes, and the possibilities are nearly endless. The glove can connect over Bluetooth to switch modes and visualize the sensor readings.
This instructable was made as part of the final project requirement in the CS graduate course "Tangible Interactive Computing" at the University of Maryland, College Park taught by Professor Jon Froehlich. The course focused on exploring the materiality of interactive computing and, in the words of Hiroshii Ishii, sought to "seamlessly couple the dual worlds of bits and atoms."
