specific Embodiment approach

[0041] The touch screen input control method of the present invention can be applied to mobile phones, PDAs or various service terminals with touch screens. The specific implementation is as follows:

[0042] The flow of a touch screen input control method disclosed in the embodiment of the present invention is as follows figure 1 As shown, including the following steps:

[0043] Step S11: When the user performs a key operation, determine the contact area of ​​the user's finger with the touch screen;

[0044] The touch screen has detection components for detecting the user's touch position. For example, a touch screen that supports multi-touch can be used to detect multiple points on the edge of the actual contact area between the user's finger and the touch screen, and determine the area enclosed by a closed smooth curve that passes through the multiple points on the edge as the user The contact area between the finger and the touch screen. At this time, when the number of points ...

Abstract

The invention discloses touch screen input control method and device as well as a mobile phone, wherein the touch screen input control method comprises the following steps of: determining a contact region of a finger of a user and a touch screen when the user presses keys; finding keys positioned in the contact region; when a plurality of keys are in the contact region, calculating contact areas which correspond to the keys positioned in the contact region; setting the key with maximal contact area as a preferred key and other keys as candidate keys; and generating key information which corresponds to the preferred key and the candidate keys. In the touch screen input control method disclosed by the embodiment of the invention, the contact region of the finger and the touch screen is used as a key selection region when the user executes the key operation, thereby reducing the possibility of using untouched keys as the candidate keys, filtering the keys irrelevant to the key operation, greatly decreasing the number of display keys, simplifying the operation process of the user selecting a target key, reducing the complexity of selection operation and enhancing the input efficiency of the touch screen.

Description

Technical field [0001] The present invention relates to the field of mobile communication technology, in particular to a touch screen input control method, device and mobile phone. Background technique [0002] Touch panel, also known as touch panel, is an inductive liquid crystal display device that can receive input signals such as contacts. When a graphic button on the screen is touched, the tactile feedback system on the screen can be driven according to a pre-programmed program Various connecting devices can be used to replace mechanical button panels, and use liquid crystal display screens to create dynamic audio-visual effects. With the development of technology, touch screens have been widely used in mobile phones, personal digital assistants or PDAs (Personal Digital Assistant, PDA) or various service terminals to replace actual keyboards as input devices for electronic devices. However, when the area of ​​the virtual keyboard displayed on the touch screen is smaller th...
