Problems solved by technology

This method has achieved certain results in the continuous input problem, but there are still many problems in practical applications, especially in simple stroke input, when the data frame is lost, that is to say, the system does not collect enough pen-down state samples Point, the average speed and distance calculated by the above scheme are often less than the preset threshold, and the writing state is misjudged as the key trigger state, resulting in subsequent input errors

Embodiment Construction

[0067] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0068] In view of the problems in the above scheme, by analyzing the characteristics of the input starting data, predict the user's input intention according to the distance it moves within a certain time, especially for the possible misjudgment problem when short strokes are input, all confirmed as buttons The input of the trigger event is further confirmed and repaired, so as to avoid misjudgment and error as much as possible.

[0069] Fig. 3 shows a diagram of a keyboard writing interface. The keyboard area is the user input area, which accepts the user's input by pressing keys or writing. Figure 3a It shows the process of inputting the word "Xun" with the pinyin input method. Figure 3b The process of handwriting inputting ...

Abstract

The invention relates to an input method supporting multimode automatic switching. The method comprises the following steps of: analyzing an input mode of a user according to first stroke information input by the user, and if input is handwriting input, entering a handwriting input mode, tracking and identifying handwriting input in real time and completing input of a single character; if the input is keyboard input, entering a keyboard input mode, feeding back a user key pressing event and recording the input track of the user, performing secondary analysis on subsequent input of the user, and if the subsequent input is handwriting input according to the secondary analysis, clearing the historical marks of the keyboard input and entering the handwriting input mode; and if the subsequent input is keyboard input according to the secondary analysis, keeping the keyboard input mode. The invention further provides an input system supporting multimode automatic switching. Particularly specific to the problem of probable wrong judgment caused by the input of short strokes, all inputs which are determined as key trigger events are further determined and restored, so that wrong judgment is avoided to the maximum extent.

Description

technical field [0001] The invention relates to the field of information entry, in particular to an input method and an input system supporting multi-mode automatic switching. Background technique [0002] With the rapid development of information technology, the accelerated integration of 3G industry and the arrival of 3G mobile communication era, new intelligent human-computer interaction applications are changing with each passing day. Among them, handwriting input and keyboard input, as two common interactive modes, are being recognized by more and more users. The handwriting input method refers to handwriting on the touch screen, and the input handwriting is converted into ASCII codes through the internal recognition system, and displayed in standard fonts. The virtual keyboard input method is to set a virtual keyboard on the terminal, and input through the selection of strokes. Due to the large number of keys on the virtual keyboard, the defect of needing to repeat m...
