Overlap handwriting input method

Abstract

The invention discloses an overlap handwriting input method. The method comprises the following steps of: when a touch unit moves on a touch screen, recording and displaying a stroke trace in a handwriting region on the touch screen; judging whether the stroke written at the present and all previously input strokes in the color of A belong to the same character; if the stroke written at the present and all the previously input strokes in the color of A belong to the same character, keeping the color of the stroke at the present constant, and otherwise, judging whether a character of a non-activated view layer exists on the screen; if the character of the non-activated view layer exists on the screen, clearing away a character image of the non-activated view layer and relevant stroke information of the character, and otherwise, defining the character consisting of all the strokes, besides the stroke at the present, in the color of A to be the character of the non-activated view layer; and submitting the character data of the non-activated view layer at the present to a recognition engine for recognition, and outputting a recognition result. By the overlap handwriting input method, a user can execute continuous handwriting input on the friendly interface according to a natural writing habit, and continuously write a plurality of handwritten words, so that the handwriting input efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of character input, and relates to a handwriting input method, in particular to a handwriting input method of overlapping writing. Background technique [0002] In recent years, as an important text input method, handwriting input method has been widely used in various mobile electronic devices such as smart phones, tablet computers, netbooks, GPS terminals, and learning machines. The handwriting input method generally means that the user writes text with a writing pen or finger through the touch screen of the electronic device, and at the same time, the electronic device recognizes the collected text writing track, converts it into corresponding text and displays it on the screen. In the process of collecting the data of the user's writing trajectory by the electronic device, the user's writing trajectory is generally displayed on the display screen in real time, so that the user can see the feedback inform...

Problems solved by technology

But a major problem of this method is when overlapping writing, due to the existence of old character strokes, can cause to be subjected to the interference of old character strokes when displaying new writing character strokes on the touch screen (such as figure 1 The overlapping writing traces of the two characters of "Science" are shown), which affects the display feedback to the user, causes visual interference to the user's new writing trace, and affects user experience and input efficiency

This problem is especially serious when writing multiple characters overlapping in succession, such as image 3 When writing the three characters of "scientist" continuously, when the third character "home" is written, the user can hardly see the stroke trajectory of the newly written character
