Abstract

The invention discloses a method for hand-written input, that the input trace of hand-written is converted into identifiable standard character on the touch screen directly, the method includes following steps: (a) set the doff-touch time; (b) the stylus contacts the touch screen, inputs, stores the input trace temporarily and display it on the touch screen; (c) when the doffing time is less than the doff-touch time, judges the input course as the other stroke, and starts the step (b), when the doffing time is longer than the doff-touch time, and executes the next step (d); (d) identifies the trace information, output it on the touch screen, and removes the input trace. The invention is easy to realize, and it can be use on several kinds of mobile terminals, and the multiple production is not needed.

Description

A kind of method that realizes handwriting input

Technical field

The present invention relates to a kind of input method of electronic product, particularly a kind of method that realizes handwriting input.

Background technology

The keyboard input is the most traditional at present, the most general a kind of input mode, but because we the employed keyboard overwhelming majority is a QWERTY keyboard, if Chinese character is imported, just must use a kind of input method of Chinese character, though various input methods based on keyboard emerge in an endless stream, for example: " five ", " phonetic ", " Intelligent ABC ", " Zheng's sign indicating number " or the like, the appearance of these input methods has also brought certain convenience for the Chinese character typing, but these input methods also exist many shortcomings simultaneously, such as: the spelling input method dialect disturbs big, phonetically similar word is many, repetition rate of coding height, and five-stroke input method needs to learn by heart coding inevitably, input rule etc., thereby various input method all can't be accomplished satisfactory to both parties neat U.S. at learnability and ease for use.

In recent years, the proposition of hand-written inputting method, input has proposed great challenge to keyboard, it is hand-written on touch-screen by built-in stylus that it refers to electronic product, the recognition system of touch-screen by inside is converted to the discernible standard letter of electronic product to hand-written various fonts and is presented on the touch-screen, so just improved the speed of input widely; And the importer need not additionally to train and can use.Yet but comparatively complicated in realization for hand-written inputting method at present, portability is not strong, and use on different terminals needs to develop once more more.

Summary of the invention

The present invention promptly is a kind of method that realizes handwriting input that proposes at problems of the prior art, and the present invention realizes simply, can use overlapping development once more by directly transplanting on multiple electronic product.

The present invention realizes by following technical proposals:

A kind of method that realizes handwriting input can directly be converted to stylus hand-written input trajectory on touch-screen discernible standard letter output and show that this method may further comprise the steps:

(a) setting is taken off and is touched timing;

(b) stylus contact touch-screen is imported, and temporarily stores input trajectory, and output shows;

(c) touch timing when stylus lifts the time less than taking off, be judged as input process and begin other stroke, continue execution in step (b), touch timing greater than taking off, then carry out next step (d) when stylus lifts the time;

(d) trace information of input is discerned, and output shows the removing input trajectory.

Further, in described step (a) before, also hand-written input state is discerned, and be to realize by following method: setting refers to touch first timing, judges stylus is referring to touch whether displacement is greater than setting minor increment in the writable area territory at touch-screen in first timing, if, then be the handwriting input state, if not, judge that then this state is the transparent transmission standby condition, not as the handwriting input state, and the stylus action is moved as common mouse.

Further, stylus is to refer to that by calculating stylus the coordinate that touches surrounding time in first timing obtains in the displacement that refers to touch in first timing.

Further, when input state was in the transparent transmission standby condition, stylus is in lifted pen state, judged that then input state enters the transparent transmission state.

Further, when input state was in the transparent transmission standby condition, the stylus contact touch-screen time, this input state entered simulation right button function state greater than referring to touch second timing.

Compared with prior art, the method for handwriting input proposed by the invention realizes simple, and is reliable, and can directly apply in most of portable terminals, need not secondary development.

Description of drawings

Fig. 1 is a kind of process flow diagram of realizing hand-written inputting method in the specific embodiment of the invention.

Embodiment

Below in conjunction with the drawings and specific embodiments the present invention is further introduced, but not as a limitation of the invention.

With reference to shown in Figure 1, be the process flow diagram of general hand-written inputting method implementation procedure.At first setting refers to touch first timing, refers to touch second timing, takes off the time of touching and first distance in the method, its middle finger touches first timing and refers to that touching second timing is the time that stylus contacts touch-screen, and refer to touch first timing less than referring to touch second timing, taking off the time of touching is that stylus takes off the time of touching touch-screen, when stylus begins to carry out in the writable zone of touch-screen when hand-written, carry out following steps:

Step 101: the writable zone of stylus contact touch-screen, judge that whether stylus is referring to touch displacement in first timing, on touch-screen greater than first distance of setting, if, this state is the handwriting input state, execution in step 102, if not, then this state is the transparent transmission standby condition, not as the handwriting input state, and the stylus action is moved as common mouse, continue execution in step 105;

Judge stylus whether the displacement on touch-screen be by reading stylus greater than first distance of setting in the changes in coordinates situation that refers to touch front and back position in first timing, computing draws;

Step 102: stylus enters in the handwriting input process, temporarily preserves input trajectory, and shows on touch-screen;

Step 103: when stylus lifts, judge whether the time of lifting surpasses to take off to touch timing, if, then show this end of input, continue step 104, if not, then show it is the other stroke of beginning, return execution in step 102;

Step 104: the stroke trace information to above-mentioned input is discerned, and output shows that on touch-screen the removing input trajectory returns execution in step 101;

Step 105: judge whether stylus is in and lift pen state, if then execution in step 106, if not, then execution in step 107;

Step 106: this state is the transparent transmission state, continues to return step 105;

Step 107: judge that whether stylus depress to surpass and refer to touch second timing in the writable zone on touch-screen, if, execution in step 108; If not, continue execution in step 107.

Step 108: this state is simulation right button function state, can be used for realizing the right-click menu function under the situation of no right mouse button, satisfies conventional application such as some copies, stickup, Quan Xuan.

The method of handwriting input proposed by the invention realizes simple, and is reliable, and can directly apply in most of portable terminals, need not secondary development.
