Hand-Mounted Sonar For the Blind 98

GeekTech.in writes "The Tacit, a wrist-mounted sonar device with haptic feedback, is like strapping a bat to your wrist to help you see. It makes use of two sonar ping sensors to measure the distance to the nearest obstacle. The relative distance to an object is then fed back to the user using two servos which apply pressure to the back of the wrist."

    You've obviously never heard of Ben Underwood (http://en.wikipedia.org/wiki/Ben_Underwood#Ben_Underwood), whom is often listed among the top ten contemporary inspirational people. Not only was he able to "see" using echolocation via clicking noises with his tongue, he excelled at tasks such as mountain biking. And he is not the last blind person able to do so.

If a 6600 used paper tape instead of core memory, it would use up tape at about 30 miles/second. -- Grishman, Assembly Language Programming
