Embodiment 1

[0024] An embodiment of the present invention provides a method for recognizing handwritten input information. figure 1 is a flowchart of a method for recognizing handwritten input information according to an embodiment of the present invention, such as figure 1 As shown, the method includes step S102 to step S106:

[0025] Step S102, the terminal acquires current posture information;

[0026] Step S104, coordinate adjustment is performed on the handwriting input information according to the current posture information, for example, coordinate rotation and other operations are performed;

[0027] Step S106, the handwriting engine recognizes the adjusted handwriting input information.

[0028] In this embodiment, coordinates of the handwriting input information are adjusted by obtaining the current posture information of the terminal, so that the terminal can effectively recognize the handwriting input information even when the terminal is tilted, thereby improving handwritin...

Embodiment 2

[0034] figure 2 It is a specific flow chart of the recognition method of handwritten input information according to an embodiment of the present invention, such as figure 2 As shown, the method includes the following steps:

[0035] Step S201: The user writes strokes by hand, and the strokes are saved as a set of point coordinates.

[0036] Step S202: When the handwriting module is created, the monitoring function RegisterChangeEvent of the movement state and posture change event (WM_GVECTORCHANGE) is registered with the gravity sensor. When the gravity sensor senses the pressure change and sends an event, the event is passed to the registered listening function. The w parameter of the WM_GVECTORCHANGE event is the changed posture. The changed attitude structure data is the degree of inclination of the current mobile phone on XY, YZ, and XZ planes. Here we only need to pay attention to the degree of inclination on the XY plane.

[0037] Step S203: Adjust the set of poin...

Embodiment 3

[0041] Corresponding to the foregoing method embodiments, the present invention further provides a terminal. Figure 4 is a structural block diagram of a terminal according to an embodiment of the present invention, such as Figure 4 As shown, the terminal includes:

[0042] The acquisition module 42 is used to acquire current posture information; the adjustment module 44 is coupled to the acquisition module 42 and is used to adjust the coordinates of the handwriting input information according to the acquired current posture information; the recognition module 46 is coupled to the adjustment module 44 for use The handwriting engine recognizes the adjusted handwriting input information.

[0043] In this embodiment, the coordinates of the handwriting input information are adjusted by obtaining the current posture information, so that the terminal can effectively recognize the handwriting input information even when the terminal is tilted, thereby improving the handwriting inpu...

Abstract

A method and a terminal for recognizing handwriting input information are disclosed. The method includes: obtaining current gesture information by the terminal; regulating coordinates of the handwriting input information according to the current gesture information; recognizing the regulated handwriting input information by a handwriting engine. The effects to improve handwriting input efficiency and to improve user experience are achieved.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and terminal for identifying handwritten input information. Background technique [0002] With the development of mobile communication technology, people increasingly use terminal devices to communicate in text through Short Message Service (ShortMessage Service, referred to as SMS), electronic mail (Electronic Mail, referred to as E-Mail), etc.; In frequent text communication, handwriting input is a very common input method. The current terminal devices have certain limitations when using handwriting input: when the user writes by hand, it is necessary to keep the mobile phone vertical as much as possible, otherwise, the recognition rate will be very low. However, in actual use, it is usually difficult for the user to ensure that the mobile phone is always in a vertical state. Therefore, the existing terminals have the problems of low input efficiency and affecti...
