1 .Product Overview

Laser Projection Keyboard is a BluetoothDevice is connected to the main keyboard for desktop computers, tablet computers, smart phones , game consoles and other devices . Projection keyboard as a new input device , which uses the built- in infrared laser transmitter projects a standard keyboard work plane contour , finger tap pattern , the click position is determined by the optical recognition mode , input completion information . Laser projection keyboard no physical buttons , with the main device via Bluetooth , compact, easy to carry, can adapt to most of the work environment .

2.Works

Laser Projection Keyboard Keyboard projector will outline the work plane projected keyboard . Its end would emit infrared light to detect objects such as fingers . When the object passes the infrared light irradiation area , the sensor will detect the infrared light reflected from an object . Keyboard operation is performed by analyzing the position and movement of objects

The need to avoid the following situations :

1 .Avoid direct sunlight

2 .Avoid low color temperature light source , such as tungsten, halogen or incandescent

3 .Avoid uneven or irregular surfaces , place the product placed on a flat surface

4 .Avoid like glass or mirror-like desktop or transparent or reflective surface

5 .Avoid placing anything between the host and the projection keyboard

Watch out

Because the product uses infrared , infrared easily lead to a strong external misuse, so to avoid direct sunlight or reflected local ,Avoid low color temperature light source , such as tungsten, halogen or incandescent.

Caveat

This product is2Class laser products.To avoid injury , do not look directly into the eyes projection keyboardLight and infrared light .
