It just doesn't get more minimal than this. The Virtual Keyboard is a bluetooth for any iPad, iPhone or Android device that projects a laser-generated keyboard onto any flat, opaque surface.
"The Class II laser device generates a 9 3/4"-wide x 4"-deep keyboard with 3/4" keys and recognizes keystrokes in three dimensions by an optical sensor that detects finger placement at different areas on the keyboard, distinguishing between a finger hovering above the space bar or a number key. An invisible infrared horizontal plane projected millimeters above the surface detects actual contact with "keys"-when the plane is interrupted by a finger, the projector assigns a keyboard character, passing it along to a paired device."
It's sure to keep up with you, with typing speeds up to 400 characters-per-minute. Its rechargeable battery provides up to 2 1/2 hours of operation from a 1 1/2-hour charge from AC using the included USB/AC adapter (or three hours via direct connection to a computer).
