Abstract

The invention provides a method and device for controlling computer equipment. The method comprises the following steps: acquiring position information of a user's facial feature point in an image according to the image taken by a camera; calculating the distance between a user's face and a screen of the computer equipment and an Z-axis direction of a user's facial coordinate system according to the position information, wherein the Z axis is a normal coordinate axis in the user's facial coordinate system which is perpendicular to a plane of the user's face; calculating the intersection point between the Z axis and the screen of the computer equipment according to the distance and the Z-axis direction; calculating a target position of a cursor of the computer equipment according to the intersection point; and moving the cursor of the computer equipment to the target position. The technical scheme provided by the invention can realize the non-contact control to the position of the cursor of the computer equipment, which enables the user to further control the computer equipment without a mouse and other physical equipment, such as clicking or double clicking a left mouse button, thereby enriching the control mode of the computer equipment, and improving the use convenience of the computer equipment.

Description

technical field [0001] The present invention relates to computer technology, in particular to a method for controlling computer equipment and a control device for computer equipment. Background technique [0002] With the advent of graphical operating systems and the rapid development of Internet technology, computer equipment has become an indispensable tool in many people's daily work and life. [0003] When users use computer equipment, they usually need to rely on their hands to perform corresponding operations to control the computer equipment accordingly, such as controlling the cursor position (also called the cursor position or pointer position, etc.) Display the scrolling control of the page and whether to click a button in the current page, etc. [0004] At present, users usually control computer devices by operating corresponding physical devices. Controls such as device cursor position, page scrolling, and button clicks. [0005] However, the inventor found in...
