Abstract:
A light projection keyboard and mouse assembly. Keyboard input and mouse operation functions are achieved by means of light projection. The light projection keyboard and mouse assembly comprises a light projection hardware module (101), a light projection keyboard area (103), and a light projection mouse area (104). A light path (309) generated by refracting, via a fingertip, light paths (308, 310) emitted by the light projection hardware module (101) is reflected to the light projection hardware module (101). The light projection hardware module (101) identifies a press key position of the fingertip or a movement distance of the fingertip, processes the information, and identifies a key position pressed by a user, a press frequency, and accurate movement of a mouse. The light projection keyboard and mouse assembly is convenient to carry and long in knocking life, can independently run, and can also be embedded into other devices.
