Are you ready to make a utility sink sized pool of water the location of your next living room game console? This demonstration is appealing, but maybe not ready for widespread adoption. AquaTop is an interactive display that combines water, a projector, and a depth camera.
The water has bath salts added to it which turn it a milky white. This does double duty, making it a reasonably reflective surface for the projector, and hiding your hands when below the surface. The video below shows several different games being played. But the most compelling demonstration involves individual finger tracking when your digits break the surface of the water (show on the right above).
There is also a novel feedback system. The researchers hacked some speakers so they could be submerged in the tank, adding a large speaker with LEDs on it in the same manner. When fed a 50 Hz signal they make the surface of the pool dance.

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!

We think most would agree that the Microsoft Kinect is a miraculous piece of hardware. The affordable availability of a high-quality depth camera was the genesis of a myriad of hacks. And now it seems that type of data is making an intriguing 3D display possible.
What you see above is a 3D monitor concept that Microsoft developed. It starts off looking much like a tablet PC, but the screen can be lifted up toward the user whose arms reach around it to get at the keyboard underneath. There is as depth camera that can see the hands and fingers of the user to allow manipulation of the virtual environment. But that’s only part of the problem. You need some way to align the user’s eyes with what’s on the screen. They seem to have solved that problem too, using another depth camera to track the location of the user’s head. This means that you can lean from one side to the other and the perspective of the virtual 3D desktop will change to preserve the apparent distance of each object.
Don’t miss the show-and-tell video after the break. As long as there’s only one viewer this looks like a perfect non-glasses alternative to current 3D hardware offerings. Continue reading “Microsoft shows off their transparent 3D desktop prototype”
