There are usually a plurality of application programs 22, and two or more of them may be operated at the same time.

7 and 8 show an example of the tablet driver 23. Here, an example is shown in which the coordinate format is switched according to the application program.

FIG. 7 shows the flow of the coordinate format registration operation. First, the keyboard 4 is operated to specify the application program 22 for which the coordinate format is to be registered (step s1), and further the coordinates in the application program 22 are designated. When the format (input device) is designated (step s2), the designated content is registered (step s3).
This registration operation can be executed for each of various application programs 22 until an end command is input from the keyboard 4 (step s4).

FIG. 8 shows the flow of the data conversion operation. First, when data is input from the tablet 1 (step s11), the operating application program 22 is judged (step s12) and the registered contents are registered. The coordinate format registered in correspondence with the application program 22 is checked (step s13). Here, if the registered coordinate format is a relative coordinate format (step s

Further, the relationship between the change amount Δx and the corresponding data MX may be tabulated in advance, or data corresponding to the acceleration is calculated from the difference between two consecutive change amount data, and this is used. It is also possible to search the table, etc.

The absolute coordinate data on the display screen is
Coordinate data mainly for displaying a mark indicating an input position by a coordinate indicator or a mouse on the display screen of the display device 5, for example, a "+" type character (hereinafter referred to as a pointer) generated from the character clutter generator 13. The above-mentioned relative coordinate format data is converted into absolute coordinate data on the display screen by accumulating the relative coordinate format data, and the absolute coordinate format data sent from the tablet is displayed. Conversion to absolute coordinate data on the screen is done by matching the scale of the coordinate axes.

Another example is shown here. Of the data normally sent from the tablet 1, only the data required by the application program is transferred, and all the data is transferred only when there is a request for detailed data. Here is an example.

FIG. 9 shows the flow of processing for the data from the tablet. First, when data is input from the tablet 1 (step sp1), the coordinates of the data are transformed (step sp2) and then all are temporarily stored. Are stored in memory (step sp3). The stored data has a high sampling rate of, for example, about 200 points / second, but for example, 20 to 20 at a predetermined time (step sp4).
40 points / second are thinned out and read (step sp5),
Further, it is transferred to the window program 21 and the application program 22 (step sp6).

When the window program 21 receives data from the tablet driver 23, it moves the above-mentioned pointer on the screen.

FIG. 10 shows the flow of operations when a request for detailed data is made. Detailed data from the application program 22, for example, the above-mentioned high sampling rate between two predetermined coordinate values, is generated in response to an operator's operation. Request for all coordinate values of
11), all the stored data are searched using the two coordinate values as search keys (step sp12). At this time, if there is matching data (step sp13), all coordinate values having a high sampling rate between the two coordinate values are read and transferred to the application program 22 (step sp14).

As the detailed data, in addition to the coordinate values input from the tablet 1, writing pressure information of the stylus pen 2 and the cursor 3, height information, inclination information, rotation angle information, and the like can be considered.

11 and 12 show the tablet driver 2
3 shows still another example, in which the coordinate format is switched according to the type of the coordinate indicator being used.

FIG. 11 shows the flow of the coordinate format registration operation. First, the keyboard 4 is operated to select the coordinate indicator, for example, the stylus pen 2, for which the coordinate format is to be registered (step st1). When the coordinate format corresponding to the stylus pen 2 is designated (step st2), the designated content is registered (step st3). Similarly, when the cursor 3 is selected and the coordinate format corresponding to the cursor 3 is designated, the designated content is registered. This registration operation can be executed for each of the various coordinate indicators until the end command is input from the keyboard 4 (step st4).

FIG. 12 shows a flow of data conversion operation. First, when data is input from the tablet 1 (step st11), identification information (flag) of the coordinate indicator is extracted from the data (step). st12). At this time, if the identification flag is a flag indicating the stylus pen 2, for example, “set (“ 1 ”)” (step st1
3) check the coordinate format registered corresponding to the stylus pen 2 from the registered contents (step st14),
If the coordinate format of the stylus pen 2 is set to the absolute coordinate format (step st15), the stylus pen 2 is directly transferred to the window program 21 and the application program 22 (step st16). Also, stylus pen 2
If the coordinate format of is set to the relative coordinate format, the coordinate format is converted to the relative coordinate format (step st17) and then transferred.

On the other hand, if the identification flag is a flag indicating the cursor 3, for example, "reset (" 0 ")", the coordinate format registered corresponding to the cursor 3 is checked from the registered contents in the same manner as described above (step st18), if the coordinate format of the cursor 3 is set to the relative coordinate format (step s
t19), converting to the relative coordinate format and transferring to the window program 21 and the application program 22. If the coordinate format of the cursor 3 is set to the absolute coordinate format, the cursor 3 is directly transferred to the window program 21 and the application program 22.

The contents to be switched depending on the type of the coordinate indicator being used include not only the coordinate format but also the amount of data, the transfer rate, etc. Further, continuous information other than the coordinate values obtained on the tablet can be transferred to the stylus pen. It is also possible to transfer as pen pressure information in the case of and to transfer as switch information in the case of a cursor. Also, a plurality of these switchings may be performed simultaneously. Furthermore, it is also possible to change the switching contents or not to perform the switching depending on the application program.

In the above-mentioned embodiment, a system comprising a tablet and a personal computer as a host computer separated from the tablet has been described, but the present invention is applicable to a system in which these are integrated. There is no end.

[0034]

As described above, according to the present invention, the data sent from the tablet is analyzed according to the request of the software that uses the data, and is converted according to the analysis result. Whether the software uses a tablet or a mouse, the data can be converted into absolute coordinate format data or relative coordinate format data without any operation. In addition, it is possible to transfer part of the data that is normally sent from the tablet and transfer all the data only when a request is made, so that the data sent from the tablet can be used for unnecessary data processing and transfer. It is possible to improve the efficiency of the entire system without spending the processing capacity of the software used.

Further, according to the present invention, since the data sent from the tablet is converted according to the type of the coordinate indicator in use, the data can be converted only by replacing the coordinate indicator in use, For example, data in absolute coordinate format can be converted into data in relative coordinate format, and it is especially easy to hold the same coordinates. By using a cursor that can use more switches, data can be converted into data in relative coordinate format. , The application program developed for mouse can be used with good operability.

Further, according to the present invention, the coordinate format and the like are registered in advance according to various application programs, and the data sent from the tablet is converted according to the operating application program. There is an advantage that the data can be converted into data suitable for a program, and even when a plurality of application programs are operating at the same time, the data can be converted into data according to each program, and can be used with good operability.
