DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details will be described below based on the embodiments of the present invention shown in the drawings.

FIG. 1 is a block diagram of the essential parts of the device of the present invention.

Reference numeral 2 denotes a data processing unit for processing data, 3
Is a storage unit for storing data, and the input data buffer 3
In addition to a and the matching pattern storage unit 3b, a display output buffer 3c is included. A display output control unit 6 is provided.

Reference numeral 4 is a data input unit having an input instruction means such as an input pen, and 5 is a data display unit having a display screen such as a tablet device.

The input data is stored in the data processing unit 2 as 2
It is digitized and stored in the input data buffer 3a of the storage unit 3. The stored data is the matching pattern storage unit 3b.
At the same time as obtaining the most approximate pattern as a recognition result by comparing it with the data in the table, the data is held in the display output buffer 3c as a display pattern. The held data is displayed on the display unit 5 as a display pattern obtained as a recognition result by the display output control unit 6.

FIG. 2 is an example of a display output graphic.

The upper hand shows the handwritten handwriting drawn by the user, and the lower hand shows the display pattern corresponding to the recognition result.

The determination as to whether to start or stop the execution of the specific process defined in advance for the display pattern on a one-to-one basis can be made at the stage when the display pattern is displayed on the display section 5.

Unlike the conventional technique, the judgment is not made after the execution of the specific process is completed.

FIG. 3 is a flow chart showing the operation of the present invention.

The data input by handwriting at 11 is stored and held as input data at 12. At 13, the above data is compared with the matching pattern. At 14, it is determined whether a specific matching pattern is confirmed. If not, at 20 a matching pattern with the next candidate is executed.
If the candidate pattern still remains at 21, the above comparison is executed, and if all candidate patterns do not match, 2
The stored data is cleared in 2 and the error message is displayed in 23.

When the specific matching pattern is determined in 14, the address information of the display pattern of the pattern is read in 15 and the display pattern for the recognition result is displayed in 16. In step 17, it is judged whether or not the specific process represented by this pattern is acceptable. If the pattern does not represent the intended process, in step 24 the state before the process is restored. If this pattern is acceptable, the corresponding process is executed in 18, and after the process is performed, when the process is no longer necessary contrary to the original purpose, it is canceled in 19 as before and the process is performed. It suffices to return to the state of, and if the processing is acceptable, the processing ends.

Reference numeral 30 in FIG. 4 (1) represents a data input display screen.

Reference numeral 32 is an input instruction means such as an input pen,
Assuming that the gesture recognition result by handwriting is set to a predetermined gesture function mode as an instruction to execute a specific process, reference numeral 31 is a handwriting representing a handwritten geometrical shape. That is, the type of a specific process that is the shape of the geometrical figure is determined, and the process is executed according to the content.

In the present invention, when handwriting is input as shown in FIG. 4 (1), the shape (geometric figure) of the handwriting input is held in the display output buffer in advance as shown in FIG. 4 (2). The window display 36 is matched with the displayed display pattern 35 and the closest pattern is used as the recognition result.
is doing. In addition to the above, the display method includes a method of dividing the screen and displaying it, a method of temporarily displaying on all screens, and the like.

As described above, according to the present invention, in the handwriting input device having the gesture function, even if the execution of the process is not completed by displaying the display pattern as the recognition result of the geometrical pattern input by handwriting, At a stage (when the display pattern is displayed), it becomes possible to know which specific process the user has executed.
