[0049] For mobile terminals that support floating touch technology, the present invention can be as follows: figure 2 implementation shown. The first embodiment of the method of the present invention comprises the following steps:

[0050] Step 1, the mobile terminal divides the screen area into M×N grid areas, where both M and N are positive integers. Commonly used division methods include 2×2, 3×3, 3×2, 3×4, etc.

[0051] Before step 1, a step may also be included: when the user needs to bring up the virtual keyboard or virtual screen to input information, the mobile terminal enters into the state of adaptively adjusting the virtual keyboard or virtual screen. Situations where the user needs to bring up the virtual keyboard or virtual screen to input information include when the user needs to send a text message, when the user needs to make a phone call, when writing an email, and any situation where information needs to be input through the touch human-machine interface....

Abstract

The invention discloses a method for adaptively regulating touch input range of a screen, and a mobile terminal. According to the method, the screen area is divided into M*N lattice areas; and the mobile terminal detects movement of the user finger to define the lattice area where the current finger projection is located and generate a virtual keyboard or a virtual screen to preview in real time on the condition that the central point of the lattice area is used as an anchoring point. The mobile terminal detects touch operation of the user finger, determines the lattice area where the user finger touches or leaves, and determines the virtual keyboard or the virtual screen generated on the condition that the central point of the lattice area is used as an anchoring point so as to be available for a user to input. Due to the method, the user can adaptively regulate touch input range of the screen, and can dynamically regulate position and size of the virtual keyboard or the virtual screen according to the user hand and current specific holding condition so as to improve user experience.

Description

technical field [0001] The invention relates to personal communication technology, in particular to a method for adaptively adjusting a screen touch input range and a mobile terminal. Background technique [0002] Since the release of the iphone in 2007, large-screen smart mobile terminals have become the mainstream of mobile terminals because they can conveniently meet the various needs of users for surfing the Internet and playing games. Capacitive touch screens have become the screen material used by most mobile terminals because they support multi-touch human-computer interaction. Smart mobile terminals with large screens bring users a good experience when surfing the Internet or playing games, but also bring some problems. In some cases where one-handed operation or two-handed quick operation is required, a smart mobile terminal with a large screen will have some disadvantages. Here are two common situations: [0003] Users operate smartphones with larger screens, su...
