Non-contact human-computer interaction method and system

Abstract

The invention discloses a non-contact human-computer interaction method and system. The method comprises the following steps of: emitting and receiving light, extracting and processing signals, and decoding and sending operating instructions. The system comprises an emitting device, a receiving device and a control device. An interaction function is realized by instructing parts to do some simple actions, and near-distance accurate operation is not required, so that far-distance human-computer interaction is realized to a certain extent. The method and system disclosed by the invention are particularly applicable to handheld electronic equipment.

Description

technical field [0001] The invention relates to a non-contact human-computer interaction method and system, in particular to a non-contact human-computer interaction method and system applied to various small electronic devices. Background technique [0002] The human-computer interaction function of the operating system is an important factor in determining the "friendliness" of a computer system. The human-computer interaction function mainly depends on the external equipment that can input and output and the corresponding software to complete. The main function of the human-computer interaction part is to control the operation of related equipment and understand and execute various commands and requirements transmitted through the human-computer interaction equipment. The devices that can be used for human-computer interaction mainly include keyboard display, mouse, and recognition devices of various modes. Early human-computer interaction facilities were keyboard displ...

[0004] 1. Huge system

[0005] 2. Complex structure

[0006] 3. High cost

[0007] 4. High power consumption

[0008] 5. High performance requirements for hardware devices, not suitable for handheld electronic devices

[0009] 6. The requirements for the working environment are high, and it is easily affected by the complex environment of light

[0010] 7. The algorithm is complex and difficult to implement

However, since this kind of sensor is evenly distributed on the display screen in the form of a dot matrix, due to the trigger sensitivity, it must be operated at a very close distance and accurately to get the required response, which is not suitable for some environments The lower pointing part cannot be positioned at close range, which limits the distance and trigger mode of non-contact human-computer interaction
