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!
