Problems solved by technology

[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

Embodiment Construction

[0038] like figure 1 As shown in the flow chart of the method of the present invention, a number of light source emitting devices are set on the equipment to emit light waves, a number of light wave receiving devices are set on the equipment to receive reflected light waves, and at the same time, an appropriate trigger threshold is set on the receiving device to shield out The light receiving device receives the reflected light signal from the environment, and simultaneously records the reflected light signal under the action of the indicating component. It should be mentioned that the trigger threshold should be set according to the ambient light waves.

[0039] Analyze the reflected light signals under the action of the indicating component collected by the light receiving devices at each position, and determine the action position of the indicating component according to the distinguishing characteristics of the reflected light signals under the action of the indicating ...

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...
