Full-screen handwriting recognition input method and system

Abstract

The invention relates to the technical field of handwriting input, and discloses a full-screen handwriting identification input method and system. The method comprises the following steps: starting a full-screen input mode; under the full-screen input mode, receiving handwriting input of a user in the whole screen region; judging whether the user finishes the current input; if so, switching the full-screen input mode into a non-full-screen input mode; and under the non-full-screen input mode, receiving character input and / or text editing instructions of the user in a specific region. By using the method and the system, user operation is facilitated, and the user can effectively control an application program.

Description

technical field [0001] The invention relates to the technical field of handwriting input, in particular to a full-screen handwriting recognition input method and system. Background technique [0002] As a simple, convenient and efficient input method, handwriting input has changed the traditional keyboard mode based on complex coding or pinyin input, and provided convenient conditions for natural human-computer interaction. Especially handwriting input appears particularly important on small-screen portable smart terminal devices. However, the traditional handwriting input method of writing in a limited area is inconvenient on small-screen devices, especially on finger-touch capacitive screen devices such as iPhones that have been selling well in recent years. It is not easy to quickly input in a limited area. [0003] To this end, the researchers proposed a scheme based on full-screen handwriting input, which allows users to freely write on the entire screen, instead of b...

Problems solved by technology

When the user is implementing the "short message sending" instruction, they need to click figure 1 The "Send" button in the middle of the screen in the shown input method interface and figure 2 The "send" button at the bottom of the screen in the shown application interface obviously brings inconvenience to the user by repeatedly positioning the same button

[0008] 2. It is difficult to effectively edit the characters in the text edit box by calling the traditional input method

For example, when a user needs to edit a text string and wants to insert a cursor at the corresponding position in the text edit box by clicking, the system often recognizes this operation as an input method start command or an input method exit command, which affects the user's real operation.

[0009] 3. In the existing method of controlling the positioning of the cursor in the text editing box by setting additional arrow buttons, first of all, the cursor control buttons need to be designed as translucent floating icons to avoid affecting the buttons on the back-end application interface, which are easily affected by the background color of the application. As a result, users often cannot clearly identify the position of the control in many applications

Secondly, the independent floating label makes users often unable to correctly understand the purpose of the button, and it is easy to confuse it with the control of the application

Again, button control fails to provide users with clear tactile feedback, so that users cannot be informed of the operating status in time

Finally, although moving the cursor through the arrow keys can realize the positioning of the text in the text editing area, it still needs to move the cursor one by one when positioning the text with multiple characters at intervals, which is inconvenient to operate
