Abstract

The invention relates to a computer control system used for computer remote control. Computer data are projected to a projection screen by a projector, and the external cursor is projected by a cursor transmitter on the projection screen. The system comprises an image capture module, a cursor signal processing module and a cursor drive module, wherein the image capture module is used to capture the images of a computer display screen, the projection screen and the external cursor, calculate the size of the play screen and the projective region size of the projection screen, separately convert the video signals of the projection screen and the lay screen to a first coordinate and a second coordinate and obtain the position coordinate and color of the external cursor in the first coordinate; the cursor signal processing module is used to calculate the dimensional proportion of the projective region of the projection screen to the display screen, calculate the position coordinate of an internal cursor in the second coordinate according to the proportion and the position coordinate of the external cursor, a cursor click processing unit generates an internal cursor click signal according to the color of the external cursor; and the cursor drive module is used to drive the internal cursor to move and click. The invention also provides a computer control method.

Description

technical field [0001] The invention relates to a computer control system and method. Background technique [0002] At present, mouse input is generally used to control the computer display, but in meetings or multimedia teaching, a projector is generally used to project the screen from a long distance. The computer is operated by remote control, so that interaction with the audience cannot be realized, which brings inconvenience to the user. Contents of the invention [0003] In view of this, it is necessary to provide a computer control system and method that can remotely control a computer. [0004] A computer control system is used for computer remote control. The data in the computer is projected onto a projection screen through a projector, and an external cursor is projected on the projection screen through a cursor transmitter. The computer control system includes: [0005] An image capture module, which is used to capture the images of the computer display scr...
