CAVIAR is a vibrotactile guidance system we are developing that can enable people with visual impairment to reach objects in their peripersonal space. This is a demo video of a prototype implementation. Here you see my colleague Sina Bahram usng the system to reach for a coffee mug.
CAVIAR stands for Computer-vision Assisted Vibrotactile Interface for Accessible Reaching. The system consists of an Android mobile phone (here a Motorola Droid) and a wireless wristband with an arm extension to hold the necessary circuit components. The wristband has 4 vibrators that are used to give directional guidance.
