Virtual keyboards, reality or fantasy?
We have long heard of virtual keyboards like this. They are projected on a flat surface and detect the movements of the hands on the virtual keyboard. Like virtual reality, but without a helmet and without gloves. They are designed to be used with mobile phones, PDAs and other devices too small to have a keyboard in good condition. "Itech": http: //www.itechdynamic.com/html/border25.htm now claims that they have a virtual keyboard that also works via bluetooth. And "they are not the only ones": http: //www.celluon.com/products/laserkey.htm who are involved in it.
We, in addition to being somewhat skeptical, agree with Engadget: it looks like a flying robot from Star Wars ("Episode I": http: //www.culturalianet.com/art/ver.php? Art = 4646, Of course).
