Not too long ago, the invisible iPhone was nothing more than   satirical fodder for the  Onion . Now, Patrick Baudisch and his team of researchers at the Hasso-Plattner Institute have moved closer to making it a reality, with a new interface that can essentially transfer an iPhone touchscreen to the palm of your hand. The device involves an Xbox-like depth camera, mounted on a tripod, that can register the movements of a person's finger across his or her palm. Special software then determines the actions these gestures would execute on a user's iPhone, before transmitting the commands to a physical phone, via WiFi radio. Unlike MIT's motion-based "sixth sense" interface, Baudisch's imaginary phone doesn't require users to learn a new dictionary of gestures, but relies solely on the muscle memory that so many smartphone users have developed. During their research, Baudisch and his colleagues found that iPhone owners could accurately determine the position ...

Microsoft's WorldWide Telescope -- a collaboration with NASA that explores high-resolution photos and 3D renders of the cosmos -- was already pretty cool, but Redmond upped the ante to incredible with the addition of a Kinect depth camera at MIX 11. Using a piece of software created with the company's upcoming Kinect SDK for Windows, Microsoft gave us a virtual tour of Earth and the surrounding stars, guided by a deep-voiced narrator holding the whole world in his hands. Of course, you'd already know that if you watched the video above, so what are you waiting for? Oh, and we've got more MIX video on the way, so stay tuned. Myriam Joire contributed to this report.
