The design scheme of the invention is characterized by easy carrying, long knocking service life, independent operation and capability of being embedded into other equipment.

Description

technical field [0001] The invention relates to a light projection keyboard and mouse, in particular to a device and method for realizing keyboard input and mouse operation functions by light projection. Background technique [0002] As input devices, keyboards and mice have been widely used and popularized. Traditional keyboards and mice are usually realized in a physical way, that is, input operations are realized through keyboard entities and mouse entities. [0003] Keyboard input usually has a variety of input methods, such as mechanical tapping of keys to achieve input, tablet phones to achieve input through simulated keyboards, laser projection keyboards to achieve keyboard input through light projection, and so on. The operation of the mouse is usually through the control movement of the mouse entity to realize the movement operation of the mouse, and the mouse operation can also be realized by means such as a touch pad and a pointing stick of a notebook.

AI Technical Summary

Problems solved by technology

[0004] The current mainstream of general keyboard input and mouse input is realized through physical physical operation, which needs to rely on physical input devices. The disadvantage of physical physical input is that it has a certain volume, weight and mechanical percussion life.
