Method and terminal for realizing cursor control

Abstract

The invention discloses a terminal for realizing cursor control. A distance measuring module is additionally arranged, measures a distance from an object moving relatively to a sensing end of the distance measuring module in an effective range, and transmits the measured distance data to a central processing module; and the central processing module analyzes the distance change tendency and the distance change quantity between the moving object and the sensing end by utilizing the transmitted distance data, determines a cursor moving direction parameter and a cursor step parameter according to preset correspondence, carries the determined cursor moving direction parameter and cursor step parameter in a navigation message, and sends the navigation message to an operating system module, so that the operating system module can control the movement of a cursor on a human-computer interface according to the cursor moving direction parameter and the cursor step parameter in the navigation message. Therefore, a user does not need pressing a mechanical key to realize moving the position of the cursor.

Description

technical field [0001] The invention relates to control technology, in particular to a method and a terminal for realizing cursor control. Background technique [0002] At present, more and more terminals have menu function options, and the user can select different function options by moving the position of the cursor. The above-mentioned terminal may be a mobile communication terminal, a fixed telephone, and the like. [0003] Taking the cursor control of a mobile communication terminal as an example, figure 1 Shows the appearance of a mobile call terminal in the prior art, where options 101 to 10 indicate the front, back, left end, right end, upper end, and lower end of the mobile call terminal in turn, and 107 indicates the display through the display screen. Man Machine Interface (MMI, Man Machine Interface) displayed to the user. By pressing the mechanical button 108 on the surface of the mobile communication terminal, the user can choose to move the cursor on the m...

AI Technical Summary

Problems solved by technology

[0009] From the above introduction, it can be seen that when the terminal realizes cursor control, the user must press the mechanical button on the surface of the terminal, and each time the cursor is pressed, the cursor on the MMI only It can move to the adjacent position once, so that in order to select a function option that is far away from the current position, the user often needs to press the mechanical button multiple times in a row, which takes a long time and the fingers are prone to fatigue
