And a signal processing software installed on the PC/Mac performs all the critical jobs: recognizing the user’s finger top, performing distance measurement and mapping the position of the user finger top to the related key value When a user presses a “virtual key”, the reflected laser light will be captured by the camera. The keyboard hardware is very simple, only three parts are required: one camera, one laser to project the keyboard pattern and a line laser for key input detection. A camera-laser system is used to perform distance measuring tasks. The laser projection keyboard relies on Computer Vision processing algoritm to work. ![]() But currently the existing product is a little bit expensive.Here, the design we introduce is open source and low-cost, and if you are interested, you can DIY your own laser projection keyboard The design supports multiple key inputs (up to 10 keys) and works just like a normal keyboard on Windows and MacOS. The idea of projecting a virtual keyboard using a laser is very cool. Hi, guys, we will continuously update our blog in the future, nearly one or two pieces per day, from which you can not only timely comprehend our products, promotion activities, tutorials and guides, but also, to some extent more importantly, a great amount of information about the innovation and maker field will be presented in this platform.Today, we will share with you something about the open source laser projection keyboard. ![]()
