Despite revealing virtually no hard facts whatsoever, Lebedev simply states the Tactus "does not have physical keys, which means there are no restrictions on their shape and size.
Any part of the keyboard surface can be programmed to perform any function or to display any images."
Strangely, Lebedev neglects to mention video is also within its remit too as the design studio demonstrates this feat with a classic snippet from Russiantastic faux-lesbian-brief-supergroup Tatu's schoolgirl-alicious "All the things she said" music video. Less titillating, but arguably more useful however are the top right shortcuts to quickly change language layouts and formatting.
