[0015]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 schematically shows the hardware configuration of a document creating apparatus according to an embodiment of the present invention. In this figure, a CPU 1 controls the entire system. Memory (ROM / RAM) 2 is ROM or RA
The operation program of the CPU 1 including an item selection / numerical value input program by a pen is stored in the former,
The latter includes C including fixed numerical value storage means and undetermined numerical value storage means.
Functions as a work area for PU1. The VRAM 3 is a display memory in which display information on the display 7 is expanded, and its storage area corresponds to the display screen of the display 7. The information in the VRAM 3 is directly accessed by the display controller (display CNT) 6 and the display on the display 7 is controlled. This display device 7 has a tablet superimposed on its display, and it is possible to perform an input operation by pointing this tablet in addition to the keyboard 5 with the pen 13. It is performed by an input operation through this tablet. Keyboard interface (KB
-IF) 4 is an interface between the CPU 1 and the keyboard 5, an FDD interface (FDD-IF) 8 is an interface of a floppy disk drive (FDD) 9, a printer interface (PRT-IF) 10 is an interface of a printer (PRT) 11, and a pen. The interface (PEN-IF) 12 is a stylus pen (PEN) 13
Interface. The pen 13 can employ various types such as a pressure-sensitive type and an electrostatic type.

FIG. 2 shows the contents of the above item selection / numerical value input program, and FIG. 3 shows an example of the numerical value input screen. Hereinafter, the processing contents shown in FIG. 2 are shown in FIG. This will be described with reference to examples. First, the outline of the screen shown in FIG. 3 will be described. The screen is shown by reference numeral 14, and the input item display 20 is shown in this screen 14.
a, 20b, 20c are arrayed, and the numerical values therein can be updated by the input processing described later. Areas corresponding to the item displays 20a to 20c on the tablet are selection instruction areas 15a, 15b, and 15c for the respective items. Each item 20a to 20c can be selected by tapping each region 15a to 15c with the pen 13.

Now, in S1 of FIG. 2, it is determined whether or not the pen 13 is activated. At this time, when the pen 13 is, for example, a pressure-sensitive type, a switch provided at the tip thereof is turned on, so that the status information of the pen 13 is activated. Subsequently, in S2, it is determined whether or not the input item tapped by the pen 13 is valid.
That is, it is determined whether or not the coordinate information from the tablet indicates the numerical value input item display area on the display screen. When the area indicates the area, the determination is YES, and the area other than the area is displayed. The determination is NO when there is. If the determination in S2 is YES, the process proceeds to S3 and the item selection process is executed. Only the selected input item on the display screen is highlighted, and the numerical information of the item stored in the confirmed numerical information storage area in the RAM is copied to the unconfirmed numerical information storage area. For example, when the area 15c is tapped, the "number of copies" is selected, and the item display 20c is highlighted.

After that, the operator moves the pen 13 so as to draw a loop while continuing to press the pen 13 against the display (tablet). Then, the coordinate information acquisition process (not shown) captures the coordinate information from the tablet at regular intervals, and the vector information is calculated from the coordinate information at each capture timing and the immediately preceding coordinate information. FIG. 7 shows the principle. In FIG. 7A, (x0, y0) is the starting point of the drawing loop and corresponds to the tap point of the input item here. (X
1, y1), (x2, y2), ... Are capture coordinate information at each timing. Every time the CPU 1 takes in this coordinate information, the vector v1 ((x0, y0) is set as the starting point, and (x1,
vector whose end point is y1), and vector v2 ((x1
, Y1) as a starting point and vectors having (x2, y2) as an end point) are sequentially obtained, and the vector information is stored in the vector information storage area of the RAM. Then, the loop shape is identified by the shape formed when these vectors v1, v2, ... Are connected, and the result is stored in the loop shape storage area of the RAM. Further, the rotational speed information of the loop is obtained from the scalar of the vector information generated by the new coordinate information and the coordinate information immediately before the coordinate information at each acquisition timing, and this is stored in the rotational speed storage area. That is, this rotation speed information is updated at each timing of capturing coordinate information. Vector information generated by the new coordinate information and the coordinate information immediately before the coordinate information at each acquisition timing of coordinate information, and the average of the directions of the vector information of the past multiple times from the time of generation of this vector information is obtained. Is stored in the rotation direction storage area as information indicating the rotation direction of the loop. That is, the rotation direction display information stored in the rotation direction storage area is updated at each timing of taking in coordinate information.

Returning to FIG. 2, in S4, the contents of the loop shape storage area are monitored, and the shape is confirmed by the information of the storage area main body by setting the flag indicating that the identification result is output. The branching process will be performed according to the shape. Here, various input processing is branched depending on whether it is a quadrangle, a triangle, or a circle. As a result of S4, as shown in FIG.
If it is, the process proceeds to S5, and as shown in FIG. 4B, the value of the corresponding item (“the number of copies” in the above example) is set to “9
9 ". When the judgment in S4 results in a triangle 17 as shown in FIG. 5A, the process proceeds to S6, in which the relevant item is set to" 0 "as shown in FIG. 5B. When the determination in S4 is a circle 16 as shown in Fig. 3 (b), the process proceeds to the variable value input process in S7 to S10. In S7, the loop is performed based on the rotation direction display information. If the rotation direction of the loop is clockwise as a result of the determination in S7, the process proceeds to S8, depending on the speed indicated by the rotation speed information. If the result of the determination in S7 is NO, the process proceeds to S9, and it is confirmed whether or not the rotation direction of the loop is counterclockwise (arrow L). Y
In the case of ES, the process proceeds to S10, and the numerical value of the corresponding item is decreased according to the speed indicated by the rotation speed information. If the determination in S9 is NO, after the processing in S5 or S6 is completed, the process proceeds to S11 to determine whether or not the pen 13 is turned off. When the determination in S11 is NO, S8, S1
After processing 0, the process returns to S4. The result of the judgment in S11 is YES.
If so, the process proceeds to S12, and the numerical value information of the undetermined numerical value storage area is stored in the defined numerical value storage area (FIG. 3).
(C)).

As described above, according to this embodiment, when the designated input for the input item is detected based on the coordinate information from the tablet (S1) and the coordinate information indicates the loop drawing operation, the drawing operation is performed. Is determined (S7, S9), and the numerical value of the designated item stored in the undetermined numerical value storage means is increased or decreased according to the result (S8, S9).
10) After that, in response to the confirmation input of the stylus pen 13, the numerical information thereof is stored in the designated item storage area of the confirmed numerical value storage means in the RAM, so that the ten-key image as shown in FIG. The input area on the tablet is not limited to the button areas 55a, 55b, ... Like the tap on 53, and the input surface of the tablet can be used largely, so that the numerical input using the tablet can be performed. It is possible to improve operability.

Further, vector information forming a drawing loop is generated on the basis of coordinate information at regular time intervals, and the direction of rotation of the drawing loop is calculated based on direction information obtained by averaging directions indicated by the vector information at a predetermined number of coordinate information fetch timings. Therefore, the rotation direction can be accurately determined without being affected by some distortion of the loop. FIG. 7B shows an example in which the loop shape is distorted. If only the respective vectors are viewed, the vectors v'1, v'3, v'4
~ V'6 is the same as clockwise when viewed as the direction of rotation,
The vector v'2 on the way has a counterclockwise rotation direction,
If each vector is judged as it is, the rotation direction is often switched, and the numerical value cannot be stabilized and varied. That point, for example, present and past 2
Vector information of times is averaged to obtain vectors v'a1 and v'a2
Since the directional information is generated as in the case of, ..., Even if the rotation direction changes in the vector in the middle due to the distortion, the average value keeps the clockwise direction, so that the numerical value variable stable operation becomes possible.

As for the loop rotation speed, the averaging of vector information can be used to gradually change the numerical variable speed, which facilitates the operation.

According to the above-described embodiment, the shape of the drawing loop is detected based on the coordinate information (S4), and the initialization processing for initializing the numerical value of the designated item to a value according to the detected shape (S4).
5, S6) is performed, which is convenient when setting a value close to the initialized numerical value.

Furthermore, since the stop of the pen 13 is detected as a definite input, the numerical value can be adjusted subsequent to the initializing of the numerical value, for example. For example, if a triangle is first drawn and then a circle is drawn clockwise while the pen 13 is operating, a numerical value close to "0" can be easily set. In this case, the triangle is determined in S4 and the process proceeds to S6, where the numerical value "0" is reset. Then, after passing through S11, it is determined to be a circle in S4, a YES determination is made in S7, and a numerical value increasing process is executed in S8.

Although the embodiment has been described above by taking the setting of the print specifications of the document preparation device as an example, the present invention is applied to the channel switching of the television, the variable audio volume, the graph preparation function of the document preparation device and the like. can do. Figure 6
(A) shows an example of the screen 20 when applied to a television, and here, a channel display section 21 is provided at the upper right of the screen 20.
Is arranged, and a channel item designation area 22 of the tablet is arranged in a part thereof. When performing channel switching, the user first taps the area 22 with the pen 13 and then moves the pen 13 so as to draw a circle 23. This increases or decreases the channel value depending on the direction of rotation. At this time, the channel numerical value is displayed on the channel display unit 21.
In real time. Then, when the desired channel value is reached, the pen 13 is released from the screen 20 to confirm the channel.

Below the screen 20, the volume value display section 2
4 is arranged, and a part thereof is arranged in the volume item designation area 25 of the tablet. When adjusting the volume, the user first taps the area 25 with the pen 13 and then moves the pen 13 so as to draw a circle 26. This increases or decreases the channel value depending on the direction of rotation. At this time, the channel value is displayed on the volume value display unit 24 in real time. Then, when the desired volume value is reached, the pen 13 is displayed on the screen 20.
The volume value is determined by moving it away from the top.

FIG. 6 (b) shows an example of the screen 20 when applied to the graph creating function of the document creating apparatus. A graph display unit 28 is arranged in the approximate center of the screen 27. The graph displayed here is a bar graph, A to E are provided as input items, and item designation regions 29a to 29e are arranged at positions corresponding to the respective display portions of the tablet. When the user creates a graph, the item designation areas 29a to 29e
Tap the one that corresponds to the item you want to input. For example, when the item designation area 29a is tapped with the pen 13 and the pen 13 is moved so as to draw a circle 30 while the switch of the pen 13 is turned on, the upper end of the bar image moves up and down according to the rotation direction and the numerical value above it. Can be increased or decreased.

FIG. 8 shows the processing contents of the numerical value input control according to the second embodiment of the present invention. The one shown in this figure is characterized in that the item selection is performed according to the shape of the drawing loop. FIG. 9 shows an example of a screen suitable for adopting this control. What is indicated by reference numeral 31 is the screen, and on each of the item display sections 32a to 32c on this screen 31, there are illustrated images 33a to 33c of shapes used when the numerical values of the respective items are variably adjusted. First, in summary, the operator, in this case,
The tip of the pen 13 is pressed to an arbitrary position on the display screen 31 (that is, an arbitrary position on the tablet input surface), and then the pen 13 is moved so as to draw a triangle 34. When the tip of the pen 13 is pressed on the screen 31, the determination in S801 is YES and the process proceeds to S802. Here, the shape is identified based on the shape identification information, and the process branches to a numerical value input process according to the result. Here, in the case of a circle, the input processing of the "print start page" (S803 to S8
07), in the case of a triangle, the input processing of the "print end page" (S807 to S812), and in the case of a quadrangle, the input processing of the "number of copies" (S813 to S817). S803 and S80 in the input processing of each item
8. In the item selection processing of S813, the numerical information of the demarcated numerical value storage area of each item in the RAM is copied to the undetermined numerical value storage area, and the corresponding loop shape display sections 33a to 33c on the screen 31 are blinked. The control processing of the identification display with other items is executed. If it is determined in S818 that the operation of the pen 13 has stopped, an input process for the numerical information in the undetermined numerical value storage area to the fixed numerical value storage area is executed in S819, and the routine ends.

Next, the processing shown in FIG. 8 will be described by taking as an example the operation of decreasing the numerical value of the "printing end page" in FIG. 9. When the pen 13 is activated at the starting point p1, the judgment in S801 becomes YES. It proceeds to S802. This S
Since the judgment result of the triangle is obtained in 802, S80
Go to 8. At this time, the numerical information of the fixed numerical value storage area of the item “printing end page” in the RAM is copied to the unfixed numerical value storage area, and the identification display processing such as blinking the triangular display of the loop shape display portion 33b is performed. Subsequently, in S809, it is determined whether or not the rotation direction of the triangular loop is clockwise. Here, since the counterclockwise rotation is performed by the operation of decreasing the numerical value, the determination result is NO, and the process proceeds to S811, and in S811, it is determined whether or not the counterclockwise rotation is performed. Therefore, the result is YE.
The result is S, and the process proceeds to S812. Then, in this step S812, the numerical value of the "print end page" is decreased. After the end of S812, the process returns to S802. The operator repeats the drawing operation of the triangular loop with the pen 13 until the value of the "printing end page" reaches a desired value, and in the system, S802 → S808 to S81.
The process of 2 → S818 → S802 → ... is repeated. Eventually, the movement of the pen 13 reaches the end point p2, the value of "print end page" reaches a desired value, and when the operator releases the pen 13 from the screen 31, the determination in S818 is YES.
Then, the procedure advances to S819, the numerical value information of the undetermined numerical value storage area is stored in the fixed numerical value storage area, and the routine is ended.

According to the embodiment described above, when the designated input for the input item is detected based on the coordinate information from the tablet (S801, S802) and the coordinate information indicates the loop drawing operation, the drawing operation of the drawing operation is performed. The rotation direction is determined (S804, S806, S809, 810, S81
4, S816), and according to the result, the numerical value of the designated item stored in the undetermined numerical value storage area is increased or decreased (S80).
5, S807, S810, S812, S815, S81
7) After that, in response to the confirmation input of the stylus pen 13, the numerical information is stored in the storage area corresponding to the designated item of the fixed numerical storage area in the RAM. Similarly to the above, when compared with the conventional tap operation on the ten-key pad, the same operability improving effect can be obtained.

Also, the apparatus of this embodiment can be applied to channel switching of television, variable adjustment of audio volume, graph creating function of a document creating apparatus, and the like. In the case of application to TV, the channel depends on the shape of the drawing loop,
Items such as volume are selected. When applied to graph creation, items A to E are similarly selected according to the shape of the drawing loop.

[0032]

As described above, according to the present invention, when the designated input for the input item is detected based on the coordinate information from the coordinate input device and the coordinate information indicates a loop drawing operation, the drawing operation is performed. The rotation direction of is determined, and the numerical value of the designated item stored in the undetermined numerical value storage means is increased or decreased according to the result, and then the numerical value information is stored in the fixed numerical value storage means in response to the fixed input of the pointing device. Since it is designed to be stored in the designated item storage area, the input area of the coordinate input device is not limited like tapping on the numeric keypad image, and the input surface of the coordinate input device can be used largely. Therefore, it is possible to improve the operability of inputting numerical values using the coordinate input device.
