Meet the tacit project, or as it's inventor describes it: “Hand-Mounted Haptic Feedback Sonar Obstacle Avoidance Asstance Device”.Using an Arduino mini pro, two ultrasonic sensors and a couple of hobby servos this device runs on a 9V battery to help the visualy impaired navigate around.
Its is a wrist mounted device that measures the distance to things from about 1 inch (2 cm) to 10 feet (3.5m) and translates that into pressure on the wrist. 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. Here’s a short video that give more information and shows it in action.
