Abstract

PROBLEM TO BE SOLVED: To improve operability in a computer system by displaying a recognition start key near an input frame when a user starts input into the handwritten character input frame. SOLUTION: When the user inputs a handwritten character by a tablet, stroke data of the handwritten character is accumulated in a memory (S21). When the user depresses the key displayed on the tablet (S22), CPU judges which key is depressed and executes a processing corresponding to the respective keys (S23). When the key depressed by the user is the recognition start key, CPU starts a handwritten character recognition processing on stroke data accumulated in the memory (S24). When the handwritten character recognition processing terminates, CPU outputs the recognized character to the other application program operating in the system as data (S25). Thus, malfunction owing to the erroneous depression of the key is reduced and time required for depressing the key is reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a handwritten character recognition device.

[0002]

2. Description of the Related Art Most of current handwritten character input devices have a plurality of handwritten character input frames and start recognition when any of the following conditions is satisfied.

[0003] (1) When the recognition start button is pressed. (2) When input is started in another handwritten character input frame. (3) When a certain time has elapsed since the last input, (2) and (3) is irrelevant to the present invention and will not be described.

Since the recognition start button is meaningful only during handwriting input, some buttons become invalid except during handwriting input, and some buttons are displayed in half-brightness. Alternatively, the function may be changed such as a recognition start button during handwriting input and a recognition candidate display button at other times.

[0005]

However, in the conventional handwritten character input device, since the position of the recognition start button is fixed,
In the case of a handwritten character input device having a plurality of handwritten character input frames, when the user inputs characters in a handwritten character input frame located far from the recognition start button, the amount of movement of the pen for pressing the recognition start button is large, and Because the amount of movement of the viewpoint becomes large, it is difficult to adjust the pen tip to the recognition start button.

As a result, there is a drawback that it takes a long time to press a wrong button to cause a malfunction or to press a recognition start button, and it takes a long time to start recognition.

In the method of providing a recognition start button for each handwritten character input frame, the ratio of the area occupied by the display of the recognition start button on the entire screen is increased, and the area available for other displays is reduced accordingly. Had the disadvantage of doing so.

[0008]

In order to solve the above problems, according to the present invention, when a user starts inputting in a handwritten character input box, a recognition start button is displayed near the input box. This makes it easier to press the recognition start button.

When the user finishes the handwriting input and starts the recognition process, the application stops displaying the recognition start button near the handwritten character input frame. Information can be displayed near the site.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. FIG. 1 shows a computer system having a handwritten character recognition function. In the figure, 11 is a CPU, 12 is a tablet, 13 is an LCD display device, 14 is a memory, and 15 is an I
/ O port.

FIG. 2 is a flowchart of the handwritten character recognition process.

The operation of the system shown in FIG. 1 will be described with reference to FIG. When the user inputs a handwritten character using the tablet, stroke data of the handwritten character is stored in the memory (21). Thereafter, when the user presses a button displayed on the tablet (22), the CPU determines which button has been pressed and performs processing corresponding to each button (23) The recognition of the button pressed by the user starts In the case of a button, the CPU starts a handwritten character recognition process on the stroke data stored in the memory (24).

When the handwritten character recognition process is completed, the CPU
Outputs the recognized character as data to another application program operating on this system (25).
The data input in this way can be stored and reprocessed by this system, or transferred to another system such as a personal computer via an I / O port.

Alternatively, if the button pressed by the user is an input cancel key, the CPU discards the handwritten input data that has been input so far, so that the user can re-enter the handwritten characters from the beginning. (26) FIGS. 3, 4, 5, and 6 show handwritten character input screens showing an embodiment of the present invention. In each of FIGS. 3, 4, 5 and 6, 31 is a handwritten character input frame, 32 is a display area of an application, 33 is a display of a normal recognition start button, 34
Is a display of a recognition start button during handwriting input.

First, as shown in FIG.
It is displayed at the position. Alternatively, the recognition start button may be displayed in half brightness or may not be displayed.

Next, as shown in FIG. 4, when the user starts inputting into a certain handwritten character input frame, a recognition start button is displayed near the input frame. At this time, the display position of the recognition start button may be a position below the handwritten character input frame. Further, the recognition start button displayed at 33 need not be displayed, or the recognition start button displayed at 33
May be moved to the position.

Next, as shown in FIG. 5, when the user starts inputting in another handwritten character input box, the recognition start button displayed near the input box that has been input up to that point is stopped, and a new button is displayed. A recognition start button is displayed near the input frame where the input has started.

At this time, the recognition start button displayed at the position of the input frame where the input has been performed previously may be moved to the position of the input frame where the input has been newly started.

Further, when an input is started in another handwritten character input frame, recognition processing of the data of the input frame input so far is started.

Finally, as shown in FIG. 6, when the recognition start button is pressed by the user to start the recognition process,
The display of the recognition start button displayed in is turned off, and the character resulting from the recognition processing is passed to the application.

FIG. 7 is a handwriting input screen showing a second embodiment of the present invention. Instead of FIG. 4, at the same time as displaying the recognition start button, a handwriting input cancel button (75)
Is displayed. At this time, the display position of the cancel button may be a position above the handwritten character input frame.

[0023]

According to the present invention, it is possible to reduce the amount of movement of the pen tip and the amount of movement of the viewpoint when the user performs handwriting input and presses the recognition start button or other buttons related to handwriting recognition. it can. Therefore, the labor for aligning the pen tip with the recognition start button can be reduced. As a result, erroneous operations due to erroneous button presses can be reduced, and the time required to press the buttons can be reduced. Therefore, the operability of the computer system can be improved.

Further, the present invention can be realized without modifying the hardware.
