How to use

Place the device on a stable, flat surface and power it on to project the keyboard layout.

Position your hands over the projected keys and type as you would on a regular keyboard; the optical sensor will register taps and send keystrokes to the paired device.

Recommendations

For best detection and accuracy, use the projection on matte, non-reflective flat surfaces with adequate ambient light but without strong direct glare on the projection area. Keep fingers close to the projected plane and avoid rapid, glancing movements that may produce missed taps. Regularly recharge the battery before long sessions and store the device in a protective case to prevent surface scratches.
