1. Product Overview:
A laser projection keyboard is a keyboard that connects to the main device via Bluetooth HID, suitable for desktop computers, tablets, smartphones, gaming machines, and other devices. As a new input device, the projection keyboard uses an embedded infrared laser projector to project the outline of a standard keyboard on the working plane. Fingers click on the pattern, and the click position is determined through optical recognition to complete the input of information. The laser projection keyboard has no physical buttons and is connected to the main device via Bluetooth. It is compact and convenient to carry, and can adapt to the majority of working environments.

2、Working Principle：
The laser projection keyboard's keyboard projector projects the keyboard outline on the working plane. Its bottom end emits infrared light to detect objects such as fingers. When an object passes through the infrared light illumination area, the sensor detects the reflected infrared light from the object. By analyzing the position and movement of the object, keyboard operations are performed.
