Problems solved by technology

However, such patents combine geomagnetic distribution values ​​and acceleration values ​​(or angular velocity values) into one model to calculate the attitude of the control device. Since geomagnetic distribution values ​​and acceleration values ​​are two independent parameters, they are combined Putting it in a model to calculate the attitude of the control device will cause a large deviation, which will cause a deviation in the positioning of the cursor

Abstract

The invention provides a method, system and device for positioning a pointer. The method includes estimating a first posture factor of a manual control device which controls the pointer in the second coordinate system according to the triaxial accelerated speed and the triaxial angular velocity of the manual control device in the first coordinate system, estimating a second posture factor of the manual control device in the second coordinate system according to the triaxial angular velocity and the triaxial geomagnetic distribution, estimating a three-dimension posture of the manual control device in the second coordinate system according to the first posture factor and the second posture factor, and mapping the three-dimension posture of the manual control device in the second coordinate system to a two-dimensional space to determine the position of a pointer, thereby the accurate positioning for the pointer which is away from the desktop and is controlled by a hand control device can be achieved.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a method, system and equipment for locating pointer positions. Background technique [0002] At present, most mice on the market rely on optical sensors or laser sensors to position the cursor. This kind of mouse needs to be placed on a desktop or other flat surfaces, and then the operator moves the mouse to control the pointer. With the popularization of large-screen display devices and the integration of three networks in TVs and set-top boxes, TVs and set-top boxes will carry more interactive content. The control method can be more convenient and free. It is often required to move the controller freely in the three-dimensional space to position the mouse cursor instead of relying on the desktop or other planes. For example, the mouse cursor is positioned based on the pointing position of the controller to the screen in the three-dimensional space, so that the movement of the mouse ...
