Embodiment Construction
[0020] Such as figure 2 As shown, a remote pointing device includes a pointing device 110, a camera device 120, a light source device 130 and a processor 140;
[0021] The pointing device 110 is pasted with a reflective film on the side facing the display screen; the camera device 120 collects images within a predetermined camera range in front of the display screen; the light source device 130 emits light that at least covers the predetermined camera range; the processing The device 140 calculates the bright spot in the image, calculates the coordinate position of the cursor on the display screen according to the bright spot, and moves the cursor according to the coordinate position; wherein, the bright spot is after the light emitted by the light source device 130 is reflected by the reflection film bright spots formed in the image described above.
[0022] Such as image 3 As shown, in this embodiment, the pointing device 110 can be any object with a reflective film past...

The invention discloses a remote pointing device and an application method thereof. The pointing device comprises a pointing device body, a camera head, a light resource device and a processor, wherein a reflecting film adheres to the side, facing a display screen, of the pointing device body, the camera head is used for collecting an image within a preset shooting range in front of the display screen, the light resource device is used for emitting light which covers at least the preset shooting range, and the processor is used for calculating a bright spot in the image, calculating the coordinate position of a cursor on the display screen according to the bright spot, and moving the cursor according to the coordinate position. In the whole process, the pointing device body only needs to reflect the light emitted by the light source, and camera equipment and power resource equipment are not needed, namely the pointing device body is simple in structure and free of periodical replacement of a power resource; meanwhile, data information does not need to be transmitted to a system through wireless transmission, users do not need to be worried about interference of outside signals, the camera head is prevented from rotating along with the rotation of the pointing device body, and then the coordinate position, in the image, of the cursor does not rotate.
Description
technical field [0001] The invention relates to the field of human-computer interaction, in particular to a remote pointing device and an application method thereof. Background technique [0002] The method of information control interaction is more and more widely used in the field of human-computer interaction, and people can realize the control of the display screen by means of remote control. [0003] A general remote pointing device has a preset light source device near the display screen. The pointing device is equipped with a camera. When the pointing device points to the direction of the screen, an image with information about the light source device will be captured. According to the position of the light source device in the image , determine the corresponding coordinate value, and send the coordinate to the host of the display, and the host will set the screen cursor through a preset algorithm according to the coordinate value. Such as figure 1 Shown: [0004] ...
