Blindsquare is giving guidance systems for the visually disabled a new twist with user-generated Foursquare data, text-to-speech, GPS and some OpenStreetMap mojo. While users are out and about, the app narrates their trip via headphones with information about nearby places, intersections or guidance to their destination. One shake of the iPhone or iPad gives users their current location and a second shake checks them in on Foursquare. The app can also be controlled via a Bluetooth remote while the device sits in a pocket or backpack. After going from concept to completion in six months, it's now out of beta and available on the App Store for $14.99. Sonar gauntlets won't let you check-in to your haunts?
