Embodiment Construction

[0046] The present invention provides a human-computer interaction method and system based on laser projection positioning. In order to make the objectives, technical solutions and effects of the present invention clearer and clearer, the present invention will be described in further detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0047] See figure 1 , Which is a structural block diagram of the human-computer interaction system based on laser projection positioning of this application. As shown in the figure, the human-computer interaction system based on laser projection positioning includes: a projection device 100, an interactive device 200, an image acquisition device 300, and a host computer 400. The image acquisition device 300 is fixed beside the projection device 100. The interactive device 200 is connected to the upper computer 400, and the imag...

Abstract

The invention discloses a method and a system for man-machine interaction and based on laser projection location. The system includes a projection device, an interaction device, an image collection device and an upper computer. The image collection device is fixed beside the projection device, the interaction device is connected with the upper computer, and the image collection device and the projection device are connected with the upper computer respectively. The method for man-machine interaction considers the traditional mouse key definition mode and the relative location mode of cursor position indication, has absolute location mode cursor position indication operation direct feel, avoids system demarcation problems, facilitates use and reduces requirements of the interaction system for environment.

Description

Technical field [0001] The present invention relates to the field of interactive technology of display systems, in particular to a human-computer interaction method and system based on laser projection positioning. Background technique [0002] With the development of computer technology, the ways of human-computer interaction are becoming more and more diversified, from mouse and keyboard to gesture, somatosensory, voice control, etc., has been developing in a direction that is convenient for users. The laser positioning interactive system is an interactive system similar to a mouse. It can use the laser to accurately locate the mouse cursor and generate mouse messages. Using this laser pointer in presentations or playing some remote control games will bring a whole new experience. [0003] Human-computer interaction systems for laser positioning in the prior art are mainly divided into two categories: [0004] One is to use the bright spots emitted by the laser pointer to complet...
