AI Technical Summary

Problems solved by technology

Taking the optical mouse as an example, since the light intensity needs to be used to calculate the center of gravity or center position, the calculation is relatively complicated
If the pointer can be constructed with a lower resolution, the cost can be reduced, but the cursor may not be positioned accurately due to the reduced resolution used to calculate the movement of the cursor position

Embodiment Construction

[0037] Please also see figure 1 and figure 2 , which respectively show a schematic diagram and a block diagram of the screen object movement control device according to the first embodiment of the present invention. The screen object movement control device 100 of this embodiment includes an image display unit 12 , a pointer 13 and a processor 14 . The image display unit 12 is used for displaying a frame 121 having a cursor 122 and a preset icon 123 . The object on the screen can be, for example, a cursor 122 (but as mentioned above, it is not limited to being a cursor and can be other controllable moving objects), which has a cursor position CP on the screen 121 . The preset icon 123 has an icon position MP on the screen 121 . The pointer 13 includes a sensor 131 for sensing the absolute or relative position of the pointer 13 and generating position information LI. Or, in another application form, the sensor 131 can also sense the relative movement of an object (such as ...

Abstract

The invention provides a picture article motion control method. The method comprises the following steps of sensing the position variation of a direct finder on a coordinate system so as to acquire a first displacement; controlling the motion of a picture article through the first displacement output ratio according to the first displacement; sensing the position variation of the direct finder on the coordinate system so as to acquire a second displacement; controlling the motion of the picture article through the second displacement output ratio when the direction change of the second displacement and the first displacement exceeds a first angular critical value, wherein the second displacement output ratio is lower than the first displacement output ratio. The invention also provides a picture article motion control device.

Description

technical field [0001] The present invention relates to a method and device for controlling the movement of screen objects, in particular to a method and device for controlling the movement and positioning of cursors. Background technique [0002] At present, when operating a computer, if a user wants to open a certain file, he usually uses a computer input device to manipulate the cursor, and then clicks an icon on the computer screen to open the file. The mouse is one of the most commonly used ones. It can locate the cursor on the current computer screen, and operate the screen elements at the position where the cursor passes by pressing keys. In addition to the mouse, the control of the cursor can also be achieved through a touchpad, a tablet, etc. (hereinafter, such computer input devices with the function of controlling the direction of movement of the cursor are collectively referred to as "pointers"). Taking the use of an optical mouse as an example, the current meth...
