Cursor control method and device based on touch tablet

Abstract

The invention discloses a cursor control method and device based on a touch tablet. The method includes the steps that touch sensitive data on the touch tablet are collected and stored in a cache which is allocated in advance, wherein the touch sensitive data are position coordinates of touch sensitive cases in the touch tablet; whether the cache is full is detected, and if yes, current cursor reference position coordinates are calculated through a preset conversion rule according to all the touch sensitive data stored in the cache; the cursor moving offset of a display system is obtained according to the current cursor reference position coordinates and the cursor position coordinates calculated last time; the cursor moving offset is uploaded to the display system so that moving of a cursor in a display screen can be controlled according to the cursor moving offset. By means of the cursor control method and device based on the touch tablet, the DPI value when a user controls the cursor of the display screen to move through the touch tablet can adapt to the size of the display screen, and convenience is brought the user.

Description

technical field [0001] The invention relates to the field of touch panels, in particular to a method and device for controlling a cursor based on a touch panel. Background technique [0002] DPI (Dots Per Inch) means dots per inch, that is, the number of dots that the cursor moves on the screen corresponding to the mouse moving one inch. For example, with a 1000DPI mouse, when moving one inch, the cursor on the screen can move 1000 points. That is to say, when the user needs the mouse to move a fixed distance on the screen, the mouse with high DPI moves a shorter distance. At the same time, when the mouse moves faster, the cursor on the screen moves faster, that is to say, the DPI is proportional to the mouse movement speed. [0003] With the rapid development of computer technology, the touchpad has replaced the mouse as a widely used cursor input method. The touchpad (TouchPad) is essentially an input device on a smooth touchpad that uses a sliding operation of a device...

AI Technical Summary

Problems solved by technology

When the display screen of the computer device is large or small, and the cursor setting of the device cannot be changed, it is very inconvenient for the user to control the cursor movement of the display screen through the touchpad

In addition, due to the sensitive response and fast moving speed of the touchpad, the positioning accuracy of the cursor may be low for the user, especially when it involves some application operations that require high positioning accuracy, which brings a lot of inconvenience to the user
