Screen-vision mouse system and realizing method thereof

Abstract

The invention discloses a screen-vision mouse system and a realizing method thereof, belonging to the technical field of computer input equipment. The screen-vision mouse system comprises a laser control pen and an integrate receiving device, wherein the laser control pen is provided with function buttons, a radio-frequency emission module and a double-wavelength laser emission module; the integrate receiving device comprises a camera module group, a radio-frequency receiving module and a signal processing module for processing information acquired by the camera module and the radio-frequencyreceiving module, an output end of the signal processing module is provided with a connector which is used for communicating with a computer mainframe; and a plurality of infrared receiving tubes arearranged around a nib of the laser control pen, and the infrared receiving tubes are connected with the radio-frequency emission module. The screen-vision mouse system and the realizing method thereof provided by the invention are simple in structure and low in cost, can realize both the remote non-contact control and the close-range screen direct input, and also can magnify object images on the screen.

Description

technical field [0001] The invention belongs to the technical field of computer input devices, and in particular relates to a screen visual mouse system and a realization method thereof. Background technique [0002] With the development of digital technology, the input technology in human-computer interaction is evolving from traditional mouse and keyboard input methods to various input methods. For example, with the popularity of smart phones and tablet computers, more user-friendly direct screen gesture input methods have been widely used. The latest Windows 7 has officially supported the gesture input method, which enables input to be performed directly on the screen of the output image, that is, the screen Direct input, eliminating the need for an external keyboard and mouse. On the other hand, on the input of large-scale screens such as teaching, exhibition, entertainment, etc., the operator often stays away from the screen and uses remote control or connection to inp...

AI Technical Summary

Problems solved by technology

Electronic whiteboards and laser projection systems are not only expensive, but also take up space and require independent installation and wiring. In addition, the positioning and calibration of the screen is relatively cumbersome

[0006] 2. The current gesture input is touch input, that is, it must be touched or very close to the screen, so there are problems such as screen wear and hygiene, and it is inconvenient to realize touch gesture input on a large projection screen that is larger than the range of human activities

[0007] 3. Although the remote control mouse laser pointer can realize non-contact control, the mouse pointer still needs to be operated by installing buttons or trackballs on the small laser pointer. The convenience of operation is limited, and it is difficult for users to obtain a good operating experience. Can't write on normal screen
