Sixth Sense is a tool for developers that lets you deliver information to your users through the sense of touch! Sixth Sense is designed to provide "augmented reality" information--like the direction to a target location--using the haptic (touch) interfaces in wearable devices.

Note that this app is just the interface for developers. If you want to actually try out haptic AR, download an app that supports SixthSense, like NavSense.
