Siemen is working on a phone which can project the screen and a keyboard onto the table (see left pic) (via BoingBoing). This sound very much like an extension of the Virtual Keyboard (see right pic). Unfortunately, the Virtual Keyboard does not work so well, at least for me.
But good to see they trying to fixed the problem by using a styles input instead of fingers :-) And they put it on a mobile phone (yes, that’s what need it most!) and also project the screen (yes!). This is one area of innovation I am watching closely :-) Will influence how UI is changing in the future especially where all the cool stuff is happening on devices.
