Pointing device and processing method in rotation

Abstract

The invention discloses a pointing device and a processing method in rotation. The pointing device comprises a sensing device, an image acquisition device and a processor. The sensing device senses whether the pointing device rotates or not at any time, and transmits the degree and the direction of a deflection angle to the processor when the pointing device rotates. The image acquisition device acquires an image of a display screen with a preset light source and transmits the image to the processor. The processor firstly confirms actual coordinates of the preset light source in the mage, calculates standard coordinates of the preset light source according to the degree and the direction of the deflection angle when the pointing device does not rotate, and then transmits the standard coordinates to a host. By the aid of the pointing device and the processing method in rotation, the coordinates of the preset light source transmitted to the host by the pointing device are the standard coordinates when the pointing device does not rotate regardless of whether the pointing device rotates or not, and accuracy of the moving position of a cursor of the display screen is ensured when the pointing device is operated to move.

Description

technical field [0001] The present invention relates to the field of human-computer interaction technology, and more specifically, to a pointing device and a processing method when rotating. Background technique [0002] The remote pointing system includes display screen, host computer and pointing device, refer to figure 1 As shown, the principle of the remote pointing system is: a preset light source 2 is arranged near the display screen 1, and the pointing device 3 includes a camera module. Image 4 of Display 1. The pointing device 3 determines the coordinates of the preset light source 2 in the image 4 according to the position of the preset light source 2 in the image 4, and sends the coordinates to the host 5, and the host 5 determines the display screen 1 through a preset algorithm according to the coordinates. position of cursor 6 on the [0003] However, when the existing pointing device is rotated, if the operator uses the rotated pointing device to move, the mo...
