While the team advertises their prototype as a multi-"touch" (with the quotations) display capable of letting users zoom and pan through a 13.3 gigapixel image, their setup is more accurately described as a gesture-driven interface, probably the biggest so far.16 cameras work together to isolate gestures on the display's 2D plane. They can also sense the size of the gesturing appendage—the system knows if the user is using the tip of their fingers, the palm, or even their head to point. Audio sensors watch out for snaps that are the signal to zoom in or out of the workspace. View the system on YouTube.
The potential for this massive gesture-driven interface is, if you will, huge. While browsing through a super-large image makes good use of the system, there are other possibilities. What about browsing through a real-time video of an entire city district, or viewing large digitized documents? In any case, the team have already tried out Quake 3 Arena and the first Homeworld on their system. Let's hope and see if the Tromso team can release more demo videos—and take steps to adapt their system for corporate or recreational purposes. More details are available here.
