Product Overview: Laser projection keyboard is a keyboard connected to the main device through Bluetooth HID, suitable for desktop computers, tablets, smartphones, game consoles and other devices. As a new input device, the projection keyboard uses a built-in infrared laser emitter to project a standard keyboard outline on the work plane. Fingers click on the pattern, and the click position is determined through optical recognition to complete information input. The laser projection keyboard does not have physical buttons and is connected to the main device through Bluetooth. It is compact, easy to carry, and can adapt to the vast majority of work environments. 2. Working principle: The keyboard projector of the laser projection keyboard will project the outline of the keyboard on the work plane. Its bottom emits infrared light to detect objects such as fingers. When an object passes through the infrared light irradiation area, the sensor will detect the infrared light reflected by the object. Perform keyboard operations by analyzing the position and movement of objects. 3. Product features: British for QWERTY keyboard layout Portable design Standard keyboard key size and spacing for easy operation No moving parts, durable for use Built in rechargeable lithium battery for easy portability window.adminAccountId=253923034;
