Sonar glove gives the gift of virtual sight to the blind

Equipping the visually impaired with new tools to navigate our world is a problem many tinkerers are working on but few have come up with such slick solution as the Tacit glove.

Developed by Steve Hoefer, the device is essentially a "Hand-Mounted Haptic Feedback Sonar Obstacle Avoidance Assistance Device" allowing the wearer to detect objects in real time by simply holding their hand out in front of them, much in the same way they would with a walking stick. Hoefer says the prototype only cost about $65 to create and offers the specs for anyone interesting in creating their own version. You can see the Tacit in action in the video below.
