Description

Handwriting input method and system combined with touch instruction

The invention relates to a handwriting input method and system, in particular to a handwriting input method and system combined with a touch command.

The handwriting input method is one of the widely used input methods, and is particularly suitable for users who are not familiar with the code input method such as Pinyin, but the handwriting input method still has a lot of inconvenience in use.

In this regard, the current industry has developed the "Handwriting Adjustment Method and Input Device" of the Republic of China Invention Patent No. 201445459, which is mainly for the user to use the input device to write the touch screen according to the user. The grip of the input device and/or the pressure exerted by the input device on the touch screen to adjust the handwriting displayed on the touch screen, thereby effectively improving the ubiquitous thickness of the handwriting displayed on the conventional touch panel and/or The problem of poor clarity.

However, the above premise must rely on the pressure value to determine whether to perform handwriting adjustment, so it is less suitable for a touch screen with insufficient pressure value detection accuracy or can not be applied to a touch screen without a pressure sensor, and the applicability is insufficient. Furthermore, the above-mentioned prior case can only be applied to adjust the appearance of the handwriting, and the function is limited.

Therefore, the present inventors have proposed a handwriting input method for improving the convenience of the handwriting input method, and implementing a touch screen without a pressure sensing function, comprising: a touch screen detecting a contact signal, And receiving a movement track before the interruption of the contact signal, so that the touch screen displays a trace corresponding to the moving track; when the moving track exceeds a preset writing movement limit When the contact signal is less than or less than the preset lower limit of the writing movement, and the contact signal continues to exceed the preset one input time upper limit value or less than the preset one input time lower limit value, the handwriting and the corresponding handwriting are not generated. The candidate word triggers a touch command.

Further, the touch command is selected from the group consisting of an insert object selection command, a note mark command, an input method control command, a window control command, and a false touch exclusion command.

Further, the touch command is a note mark instruction, and the note mark instruction is a line instruction, a geometric insertion instruction, a ground color indication instruction, a stroke color replacement instruction, and a one-line editing instruction.

Further, when the touch command is triggered and another contact signal is not received again after a preset command input time, it is determined that the touch command is terminated by an erroneous operation.

The invention also relates to a handwriting input system combined with a touch command, comprising: a processing unit; a database connected to the processing unit, the database comprising a command data, the command data comprising a writing movement upper limit distance or a writing movement a lower limit distance and an input time upper limit value or an input time lower limit value; a touch screen connected to the processing unit for receiving a contact signal and receiving a movement track before the contact signal is interrupted, so that the The touch screen displays a trace corresponding to the moving track; a touch command triggering module is connected to the processing unit, and includes a touch command comparison module and a touch command generating module, and the touch command comparison mode a writing movement time for comparing an input time of the contact signal and the movement track; when the input time exceeds a preset input time upper limit value or less than a preset one input time lower limit value, and when When the moving track exceeds a preset writing movement upper limit distance or less than a preset writing movement lower limit distance, the touch instruction generating module does not generate the pen And for a candidate should handwriting, but rather trigger a touch command.

Further, the erroneous operation determining module is connected to the processing unit. When the touch command is triggered and another contact signal is not received again after the preset one command input time, the erroneous operation determining module determines that the operation is erroneous and ends the operation. Touch command.

According to the above technical features, the following effects can be achieved:

1. It can judge whether to trigger the touch command according to the movement track and the writing movement time of the handwriting input, so the use can be not limited to the touch screen with the pressure sensing function to provide better applicability.

2. During the handwriting input process, the touch command can be triggered according to the demand, so that the user does not have to find the location of the specific instruction, and the convenience of handwriting input is improved.

3. The touch command can be a note mark instruction, so that the user can quickly mark the focus of the handwriting input during the handwriting input process, so as to further improve the convenience of the handwriting input. However, it is not limited to the application of the note marking instruction, and may be applied to the insertion object selection instruction, the input method control instruction, the window control instruction, the false touch exclusion instruction, and the like.

4. When the touch command is triggered, if the contact signal is not input within a certain command input time, it will be judged as an erroneous operation and the touch command is automatically ended, so that the use is more user-friendly.

In combination with the above technical features, the main functions of the handwriting input method and system of the present invention combined with the touch command will be clearly shown in the following embodiments.

Please refer to the first figure, which discloses a handwriting input system (100) combined with a touch command according to an embodiment of the present invention, comprising: a processing unit (1), and a database (2) connected to the processing unit (1), a touch screen (3) and a touch command triggering module (4), wherein: the processing unit (1) is a preset central processor of the touch screen (3), and can be used for receiving and calculating the touch Control the contact signal of the screen (3).

Referring to the first figure, the database (2) includes a command data (21), the command data (21) includes a writing movement upper limit distance or a writing movement lower limit distance, and includes an input time upper limit value. Or enter the data of the time limit. The upper limit of the writing movement can be referenced according to the screen size of the touch screen (3). For example, if the screen width of the touch screen (3) is 15 cm, the upper limit of the writing movement can be 10 cm, and the lower limit of the writing movement The distance can be 0.01 cm, which is obviously different from the writing distance of the general handwriting input, and the input time upper limit value can be, for example, 20 seconds, and the time lower limit value can be, for example, 1 second, which is obviously different from the general handwriting. Enter the input time, which can be used to determine whether the user is a general handwriting input.

Referring to the first figure, the touch screen (3) can be a resistive type, a capacitive type, etc., for receiving a contact signal, and receiving a moving track before the contact signal is interrupted, and initializing the contact signal. The position, the interrupt position, and the information of the movement track are transmitted to the processing unit (1) for calculation, so that the touch screen (3) displays a trace corresponding to the movement track.

Referring to the first figure, the touch command trigger module (4) includes a touch command comparison module (41) and a touch command generation module (42), and the touch command comparison module ( 41) The touch command generating module (42) is configured to trigger a touch command for comparing an input time of the contact signal and a writing movement time of the moving track. Preferably, a misoperation determination module (5) is further connected to the processing unit (1) for determining whether the user operates by mistake. In detail, when the touch command is triggered and another contact signal is not received again after a preset command input time, the erroneous operation determining module (5) determines that the touch command is terminated by an erroneous operation, thereby allowing More user-friendly.

The present invention is also a handwriting input method in combination with a touch command. A computer program product can be constructed in a program manner, and the program product is stored in a recording medium for an electronic device having a touch screen. : Smart phone, tablet, personal digital assistant (PDA) read, or stored in a server for online download to perform the aforementioned handwriting input method combined with touch commands.

For the second and third figures, the handwriting input method combined with the touch command mainly includes: a one-stroke input step and a trigger touch command. The handwriting input step: when the user touches the touch screen (3) with a touch object (A) such as a stylus or a finger, the touch screen (3) detects a contact signal. Then, the touch screen (3) detects a movement track before the contact signal is interrupted, and performs operation according to the initial position of the contact signal, the movement track, and the interruption position of the contact signal, so that the touch screen is (3) Display a trace of the corresponding trajectory.

For the continuation, please refer to the fourth figure, in conjunction with the first figure, the step of triggering the touch command: the touch command comparison module (41) compares the distance between the moving track and the input time of the contact signal. When the moving track exceeds a preset writing movement upper limit distance or less than a preset writing movement lower limit distance, and the contact signal continues to exceed a preset one input time upper limit value or less than a preset one input time lower limit value The touch command generation module (42) will trigger a touch command (the handwriting and a candidate word corresponding to the handwriting are not generated). For example, the input time of the contact signal is extremely short (less than 1 second), but the aforementioned movement The distance of the track is more than 10 cm, thereby determining whether the user wants to trigger the touch command; or the input time of the contact signal is extremely long (more than 20 seconds), but the distance of the moving track is less than 0.01 cm. It can also be judged that the user wants to trigger the touch command, and other examples can be used in the same way. The main purpose is to determine whether the user wants to trigger the touch command by using the abnormal state of the non-handwriting input habit. Preferably, the two conditions of the input time lower limit value and the writing movement upper limit distance are used as a judgment basis, or the two conditions of the input time upper limit value and the aforementioned writing movement lower limit distance are used as a judgment basis to exclude most writing. Habitual situation.

In the embodiment, the touch command is a note mark instruction, and the note mark instruction is, for example, a scribe line instruction (S2) that can provide a scribe line (S1) (as shown in FIG. 5), and an insertable geometric figure (S2) ( A geometry insertion instruction as shown in FIG. 6 can increase the handwriting color (S3) (as shown in FIG. 7), and can change the handwriting color (S4) (as shown in the eighth figure). A one-step color change command, a change of handwriting pitch, a handwriting thickness, a stroke line shape or a handwriting size (S5) (as shown in the ninth figure), etc., can be used for the note-assisted marking focus. However, it is not limited thereto. For example, an insertion object selection instruction for inserting a multimedia material such as a photo, a movie or a music may be selected; and the handwriting input method is turned off or switched to an input method control command of the keyboard input method or the voice input method; Switching the current window to a window control command of other windows; prohibiting other programs (such as calls, text messages, instant messaging, etc.) from executing, to avoid a false touch exclusion command that the user accidentally touches during handwriting. The main purpose is to allow the user to instantly trigger a specific touch command according to his or her own needs during the handwriting process. Moreover, the touch command can be a touch command for presetting a specific function, or can also replace a touch command of a different function according to the user's own needs.

Referring to the first figure, preferably, the method further includes an erroneous operation determining step. When the touch command is triggered and the other one of the command input times (for example, 3 seconds) is not received again, the erroneous operation is judged. The module (5) judges that the touch command is terminated by erroneous operation, thereby making the use more user-friendly.

In view of the foregoing description of the embodiments, the operation and the use of the present invention and the effects of the present invention are fully understood, but the above described embodiments are merely preferred embodiments of the present invention, and the invention may not be limited thereto.
