No need to talk about the much-hyped virtual keyboard, right? Ok, just to refresh your memory then… a company called ITECH created a virtual keyboard that projected an image on a table (or any other surface for that matter) and to type, you just had to tap on the projected keyboard. I never had the product in my hands… until now, and the experience with it was very good to say the least. There is a Bluetooth version of this keyboard, and it’s available on Expansys.
