This Swedish innovation is nothing else than magic. I do have a sense of that its going to standard soon and like Intel inside it will be Senseboard inside in every computer.

Senseboard wearable data entry platform is a small device that attaches to the palm of the hand and allows users to type on any surface as if it were a keyboard. It works by measuring hand and finger movements, and determines the appropriate keystrokes, mouse movements or gestures.

Personally I hope for the next step, don’t believe in using my fingers – to think should be enough (but this is an good start).
