A virtual keyboard
The Cube Laser Virtual Keyboard shows us a glimpse of how our future keyboards has evolved -- from hardware to touchscreen -- and now projection.
The keyboard has a full QWERTY layout which is projected across any flat surface, together with a "mouse mode" which lets you use your finger when typing. It is connected wirelessly to most laptops and many mobile devices, including the iPhone and iPad, and charges via USB. At the moment, the rechargeable battery is able to last for 150 minutes.
