This Laser Projection Bluetooth Keyboard will project a full size keyboard on any flat surface. And it uses laser tracking technology to follow the location of the operator.
This Laser Projection Bluetooth Keyboard has Power Saving function. if you take some time off, it will decrease the brightness. Then it is easy to turn it back on, just one click.
When you press every key on the projected keyboard, the device will make "beep" key stoke sound. If you prefer quiet times, just hold the bottom FN and P to turn off the volume.
The laser display isn’t very bright under standard office light; you can configure this by holding the FN bottom and the up and down arrows to change the brightness.
It's really surprising to see how quickly registers each bottom press. Tracks natural movement of your finger. The best one even detect over 300-characters/minute.
