Sonar Gauntlets Ping a Way for the Blind
GPS and Google Maps feature been a big help for those of us without a sensation of direction, only what if you couldn't see anything at all? That's where devices like the Tacit, a wrist-mounted asdic device, come into play.
The sonar gauntlet, designed and built aside Steven Hoefer, uses deuce sonar ping sensors to measure distances around you, and help you navigate. The relative distance betwixt you and nearby objects and obstacles is calculated by the amount of time IT takes for the signal to get well to the gimmick, impartial like echo sounding victimised by wacky. The glove is also equipped with two servos that implement pressure to your hand based on how close an object is.
The wrist-affixed device tin good sense objects from anywhere between about 1 column inch (2 curium) to 10 feet (3.5m) away. It's also pretty quick, with a general response time of mere fractions of a second. The whole device is self-contained: IT's controlled by a Arduino pro miniskirt microcontroller and powered away 9-volt battery.
Hoefer says this is just the first prototype and it can be improved upon: The device could well be made about half its current size, the servos can be replaced with audio cues to avoid cheek damage from constant pressure, and the batteries should represent reversible "with a blind-hail-fellow charging method acting, either radio receiver[ly] or magnetically-aligning power secure."
If you have your own ideas on how to improve it operating theatre neediness to build one for yourself, you buttocks. The circuit design and software are free under a full general "don't be a twitch" Creative Common sit that LET's you "make information technology, learn from it, teach it, improve IT, modify it. Just share what you do, give deferred payment, and don't deal any without contacting [Hoefer] first.
