This is the Bluetooth device that projects a laser-generated keyboard
onto any flat, opaque surface, providing an instant keyboard for any
iPad, iPhone, or Android phone. 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. Keeps pace 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.
