Though their Optimus Maximus keyboard still hasn't yet been shipped in volume, Art. Lebedev have already prototyped a new keyboard design which works differently from an OLED screen built into every key; rather, it uses one huge touchscreen which not only allows the keys to change in size and functionality, but can also be used for things like video playback etc.

Whether The Optimus Tactus makes it into full production or not is not yet known. You can view more images and details on it at the official website and also over at XBit Labs.

Art Lebedev, a leading design studio from Russia primarily known for its Optimus series of keyboards with visualization, on Friday announced its new concept, which will use rather conservative touch-screen technology. But while touch-screens have been known for ages, the Optimus Tactus may involve rather complex technology.
