This project uses ultrasonic sensors connected to an Arduino Pro and servos that nudge the wearer when an obstruction is detected.

It’s wrist mounted and senses objects from about 1 inch (2 cm) to 10 feet (3.5m). It has generally fast response time (fractions of a second) to quickly navigate complex environments. It’s designed to help a vision impaired person to navigate complex environments. Mounted to the back of the hand, the force feedback means it doesn’t 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.

    I got an iPad 2-32GB for $ 23.87 and my girlfriend loves her Panasonic Lumix GF 1 Camera that we got for $ 38.76 there arriving tomorrow by UPS. I will never pay such expensive retail prices in stores again. Especially when I also sold a 40 inch LED TV to my boss for $ 657 which only cost me $ 62.81 to buy. Here is the website we use to get it all from, http://x.co/Z9j7
