Ultra-Portable Virtual Touch Laser Projection Keyboard Wireless Bluetooth Support
This projection keyboard will work via Bluetooth HID. connection to main devices, like Tablet PC, Smartphone, Desktop PC and Video game. As a new input device, using the built-in infrared laser transmitter to project the standard keyboard on the working surface,you can locate the click position and input the information by the method of optical identification. Without physical keyboard, small size, easy to carry, this projection keyboard can adapt to most of the working environment.
How This Product Works:
This product emits infrared light from the lower end of the product to detect objects such as fingers. When an object passes through the are illuminated by the infrared light source, any infrared light reflecting off an object is detected by the sensor.
Information on the position and movement of the object is then analyzed to perform the product’s role as a keyboard.
