posted September 26 2011 10:11.29 by Giorgos Lazaridis

Project Tacit: Sonar For The Blind. This is how the maker named this gauntlet. Itís wrist mounted and senses objects from about 1 inch (2 cm) to 10 feet (3.5m). It has a fast response time to quickly navigate complex environments. Itís designed to help a vision impaired person to navigate complex environments. Mounted to the back of the hand, the force feedback means it doesnít interfere with other assistance devices that mount elsewhere and use audio feedback cues. The learning curve is measured in seconds, everyone who has worn it has figured it out immediately. Hereís a short video that give more information and shows it in action.
