The latest V2 laser keyboard is more compact, more reliable and a 3D printed framework.Using lasers to create a virtual keyboard? This seems to be only existing in sci-fi movies. Well, with this Laser Keyboard Kit, you will not only be able to tap on laser projections as the keyboard, but also program it to be anything you want, such as a laser multi-touch pad. With a few quick and simple assemblings and calibratings, your laser projection keyboard is ready to glow in the dark!
A laser projection keyboard is a form of computer input device whereby the image of a virtual keyboard is projected onto a surface: when a user touches the surface covered by an image of a key, the device records the corresponding keystroke.The projection is realized in four main steps and via three modules: projection module, sensor module and illumination module. The main devices and technologies used to project the image are a diffractive optical element, red laser diode, CMOS sensor chip and an infrared (IR) laser diode
