The invention relates to a distance input system and a distance input method based on an infrared reflection type photoelectric detection dot matrix. The distance input system comprises a micro controller unit, an upper computer and a photoelectric detection module, wherein the photoelectric detection module is connected with the micro controller unit; the micro controller unit is connected with the upper computer in a wireless or wired manner. An interaction main body in a three-dimensional space is continuously positioned in real time through the infrared reflection type photoelectric detection dot matrix, so that interaction motion identification and information input are further realized. The distance input system provided by the invention can be normally used under various lighting conditions; an image is processed in real time without complicated software and hardware; the interaction motion is high in response speed, high in identification accuracy and more in identification variety; moreover, the system is simple in structure, convenient to use and high in cost performance.
Description
technical field [0001] The present invention relates to the technical field of electronic device input, and further relates to a novel air-isolated input system and input method that utilizes infrared reflective photoelectric detection technology to realize human-computer interaction information input. Background technique [0002] Traditional input devices such as keys, mice, touch screens, etc., require direct contact with the user's fingers, so there are some application constraints in certain occasions, such as: medical staff working in the operating room are inconvenient due to sterile requirements Perform some direct contact operations; in some large-scale assembly speeches, contact interactive input operations will affect the full performance of the speaker; use contact public self-service equipment in hospitals, elevators, stations, etc., will increase germs chance of cross-infection. [0003] In recent years, the remote input systems based on camera and image proce...
