Update: using your forearms as a UI

This image should look familiar to regular readers. It’s a concept that [Chris Harrison] has been working on for a while, and this hardware upgrade uses equipment which which we’re all familiar.

The newest rendition, which is named the Omnitouch, uses a shoulder-mounted system for both input and output. The functionality is the same as his Skinput project, but the goal is achieved in a different way. That used an arm cuff to electrically sense when and where you were touching your arm or hand. This uses a depth camera to do the sensing. In both cases, a pico projector provides the interactive feedback.

There’s a couple of really neat things about this upgrade. First, it has a pretty accurate multitouch capability. Second, it allows more surfaces to be used than just your arm. In fact, it can track moving surfaces and adjust accordingly. This is shown in the clip after the break when a printed document is edited in real time. Pretty neat stuff!
