Embodiment 1

[0052] (1) When the user performs handwriting input in the handwriting input box of a mobile terminal (for example, a mobile phone), the eraser function needs to be used, and the mobile phone receives the Erase message and the pressed coordinate value;

[0053] (2) When the mobile phone receives the Erase message, take the current pressed coordinate as the center, and take the value set by the user as the side length (for example, the side length is 8 pixels), and simulate a square virtual eraser, which will be located in the square erasure of handwriting;

[0054] (3) Drag the eraser to erase existing strokes continuously like a pencil eraser;

[0055] (4) If you change to a pen, you can continue handwriting input.

Embodiment 2

[0057] (1) When the user performs handwriting input in the hand editing area (such as a short message editing area) of a mobile terminal (such as a mobile phone), an eraser needs to be used, and the mobile phone receives an Erase message and the pressed coordinate value;

[0058] (2) If the pressed coordinate point is located in the area where a certain input character image is located, then delete the character;

[0059] (3) Drag the eraser continuously to delete consecutive phrases or sentences.

[0060] Figure 4 It is a structural block diagram of a mobile terminal according to an embodiment of the present invention. The device for realizing the eraser function includes: a resistive touch screen 10 , a processor 12 and a stylus 14 . Wherein, the processor 12 may further include:

[0061] The calculation module 120 is used to calculate the resistance value of the touch point in response to the touch operation of the stylus on the resistive touch screen;

[0062] Judging...

Abstract

The invention discloses an eraser function realization method, a mobile terminal and a touch pen used for the mobile terminal. The method comprises the following steps of: responding a touch operation of a user to a resistive touch screen of the mobile terminal, and calculating the resistance value of a touch point; judging whether the resistance value satisfies the erasing condition; measuring the position interval of the touch point; and executing an erasing operation on characters in the position interval. According to the technical scheme provided by the invention, the eraser function can be realized on the mobile terminal, and the user experience is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for realizing an eraser function, a mobile terminal and a stylus for the mobile terminal. Background technique [0002] As we all know, the short message service has created tens of billions of market revenue for the mobile communication industry. As people get used to sending and receiving short messages during communication, handwriting input has also become the demand of more and more mobile phone users. Handwriting input means that mobile phone users can handwrite on the mobile phone screen through the built-in stylus, and the mobile phone uses the internal recognition system to convert various handwritten fonts into standard fonts that can be recognized by the mobile phone and display them on the mobile phone screen. Improve the speed of typing. Currently, mobile phones with handwriting input are becoming more and more popular. [0003] However, in the related a...
