As a result, all the processes performed for the user operating the valuator device are completed.

[0005]

In the conventional display system as described above, every time an input from the valuator device is detected, a conversion matrix is calculated for that input. Therefore, when the input from the valuator device occurs continuously, the control flow is as follows: input detection → calculation of conversion matrix → conversion processing (result display) → input detection → calculation of conversion matrix → …… Becomes

Generally, the time spent for calculating the conversion matrix is relatively large in the sense that it is calculated in conjunction with the input of the valuator device. Therefore, in the case of this display method, the input from the valuator device is continuously generated. When you do, there is a problem that the response becomes worse.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. In this interactive graphic display system, a conversion matrix calculation unit 11, a conversion matrix storage unit 12, a valuator device input detection unit 14 are provided. , Transformation matrix determination unit 15
And a conversion processing execution unit 16. In addition, there are a valuator device 13 and a display 17 as input / output devices for processing.

The conversion matrix calculation unit 11 calculates a conversion matrix of a conversion to be performed on an input from the valuator device 13, which is assumed in advance when the system is activated. The conversion matrix storage unit 12 stores the conversion matrix calculated by the conversion matrix calculation unit 11 as a pair with the input value from the valuator device 13 assumed at the time of the calculation. The valuator device input detection unit 14 detects that the user has operated the valuator device 13. The conversion matrix determination unit 15 compares the content stored in the conversion matrix storage unit 12 with the detection result of the valuator device input detection unit 14 to determine the conversion matrix actually used for conversion. The change process execution unit 16 actually performs the conversion process using the conversion matrix determined by the conversion matrix determination unit 15 and displays the result on the display 17.

Next, the control flow will be specifically described.

Now, a dial box is used as the valuator device 13, and enlargement / reduction by turning the dial 1 left and right (turning right to enlarge, turning left to reduce), dial 2 left and right. Rotation around the X-axis by turning (turning clockwise to the positive direction, turning counterclockwise to the negative direction), and turning the dial 3 left and right to the left and right of the screen are displayed respectively. It is assumed that it is performed on the existing figure and is displayed again on the display 17.

When the system is started, first, as the conversion matrix to be converted when the user performs a dial operation, the dial operation amounts of dials 1, 2, and 3 are -7, -4,-. 1, +1, +4, +7
Assuming the case of (the dial is positive when turned to the right and negative when turned to the left), the transformation matrix calculation unit 11 calculates 18 transformation matrices. Then, the calculated 18 conversion matrices are in the form of a table which is paired with the input values (dial number and dial operation amount) from the dial assumed at the time of calculation, as shown in FIG. Stored in 12. The processing up to this point is performed when the system is started, and the control is transferred to the valuator device input detection unit 14.

The user turns the dial 1 to the right to instruct to enlarge the displayed figure, then turns the dial 2 to the left to instruct to rotate the displayed figure in the negative direction around the X axis, and thereafter. It is assumed that the dial 3 is turned to the right to give an instruction to move the displayed figure to the right of the screen. The valuator device input detection unit 14 internally has a queue structure as shown in FIG. 3 (a structure in which the input becomes a queue and is taken out from the head), and when the user performs a dial operation, the processing is performed according to the operation order. To do. When the user completes the dial operation shown above, the contents of the queue of the valuator device input detector 14 are as shown in the internal state 41 of the queue in FIG. A total of 10 inputs are accumulated in the queue, 4 from the top are the inputs generated by turning dial 1 to the right, and the next 3 are by turning dial 2 to the left. The following three are the inputs generated by turning dial number 3 to the right. In each input, one input is represented by a pair of a dial number turned and an operation amount of the dial. Here, the valuator device input detection unit 14 takes out the first input (in this case, the input by turning the dial No. 1 by the operation amount +1), and the control is transferred to the conversion matrix determination unit 15. At this point, the state of the queue of the valuator device input detection unit 14 is like the internal state 42 of the queue in FIG. 3 because the head input is taken out. The conversion matrix determination unit 15 compares the input currently fetched from the valuator device input detection unit 14 with the conversion matrix storage unit 12 stored as shown in the table of FIG. decide. In this case, the valuator device input detection unit 14
Since there is a match in the table of FIG. 2 with the input content extracted from, the conversion matrix to be performed is
Determined to be M4. When the conversion matrix is determined, the control is then transferred to the conversion processing execution unit 16. The conversion processing execution unit 16 actually converts the display graphic by the conversion matrix M4 determined by the conversion matrix determination unit 15, and the result is displayed again on the display 17. As a result, the process for the first input is completed, and the control is transferred to the valuator device input detection unit 14 again. The valuator device input detection unit 14 extracts the head input of the queue as in the previous case. Since the state of the cue is like the internal state 42 of the cue in FIG. 3, the input content extracted here is the input corresponding to turning dial 1 by the operation amount +5. At this point, the state of the queue of the valuator device input detector 14 is the state 43 of FIG.
become that way. Next, the conversion matrix determination unit 15 determines the conversion matrix by collating the input contents extracted by the valuator device input detection unit 14 with the table of the conversion matrix storage unit 12 of FIG. , In this case, there is no match with the input contents. In such a case, the dial number that matches and the operation amount that is the closest is selected from the table of FIG. 2 to determine the conversion matrix. In this case, in the table of FIG. 2, it is determined that the corresponding conversion matrix M5 obtained by turning dial 1 by the operation amount +4 is applicable to it. Then, the result of conversion actually performed by the conversion process execution unit 16 using the conversion matrix M5 is displayed on the display 17, and the process for the second input is also completed. Similarly, the input at the head of the queue of the value device input detection unit 14 is taken out, and the extracted input contents are collated with the stored contents of the conversion matrix storage unit 12 shown in FIG. The conversion matrix is determined, conversion processing is performed by the conversion processing execution unit 16 using the determined conversion matrix, and the result is displayed on the display 17.
Repeat the process of displaying in. When the processing for all the inputs in the queue of FIG. 3 is completed (that is, the queue is in an empty state), the processing for all the dial operations performed by the user is completed. The control enters an input waiting state in the valuator device input detection unit 14, and the user restarts the dial operation to restart the process.

[0015]

As described above, the present invention is a system for calculating the transformation matrix in the processing from the detection of the input in the valuator device to the redisplay of the graphic in response to the input. By performing the operation at the time of starting in advance, it is possible to shorten the processing time from when the user operates the valuator device until the figure is redisplayed.
