There has also been a method of inputting and instructing a small time difference between the direction and amount of movement of a moving target (second progress control method). In this progress control method, the result of the control appears as an integrated value of a change in a target moving speed and a moving direction within a predetermined time. For example, it has been used in conventional car racing games, ski games, and action games that move in a maze.

[0013]

Embodiments of the present invention will be described below in more detail with reference to the drawings. Figure 1
FIG. 2 is a block diagram showing an embodiment of a virtual reality reproducing apparatus and a program thereof according to the present invention, and FIG. 2 is a diagram illustrating a display operation of the virtual reality reproducing apparatus according to the present embodiment. The virtual reality playback device 10 of the present embodiment is realized by, for example, a video game machine such as a personal computer or a TV game machine, and inputs a displacement of an operation unit, for example, a displacement from a reference point to an input operation position. , An analog input device 11 such as a game controller, a display device 12 such as a CRT or LCD for displaying a game target image, and an arithmetic processing device 13 including a CPU, a RAM, a ROM, and the like for controlling the progress of the game. ing.

As shown in FIG. 2, the arithmetic processing unit 13 stores a plurality of motion images Yi obtained by subdividing a series of motions of the game object image for each minute time. The progress of the game is controlled so as to be reproduced on the display device 12 in association with the displacement Xi of the analog input device 11. Specifically, the arithmetic processing unit 13 stores in the storage means an analog input displacement: time correspondence table 14, a time: motion data correspondence table 15, a motion data file 16, an image data file 17, and the like. ,
Progress control is performed according to a flowchart described later.

Next, a procedure of a control program of the virtual reality reproducing apparatus according to the present embodiment will be described. In step #A, an analog data input operation is performed. That is, the displacement amount from the reference point of the analog input device 11 to the input operation position is acquired.

In step #B, video output data is created. For example, the analog input data input in step #A is associated with the absolute time Ti of a series of operations assumed in advance using the analog input displacement: time correspondence table 14. Then, in order to create a video to be fed back from the absolute time TTi, the person 3D data Di which is a fragment of the time of the motion Mi assumed from the time: motion data correspondence table 15 is created.

FIG. 3 is a diagram for explaining an analog input displacement: time correspondence table 14 and a time: motion data correspondence table 15 of the virtual reality reproducing apparatus according to the present embodiment. In FIG. 3, each symbol is as follows. X: a value such as 0 to 128, and the maximum value (max) differs depending on the resolution of the analog input device 11. T: A value obtained by dividing a general operation time of a series of operations by the above-mentioned max value as a unit. M: A serial number is given to a situation for each frame obtained by decomposing a series of operations in a unit time. D: 3D polygon data group and texture data of the motion.

The table of FIG. 3 shows two tables for easy understanding.
The two tables are shown together. The item of the absolute time T is used for passing parameters. here,
The reason why the item of the absolute time T is inserted between the analog input displacement X and the resulting motion data D will be described below. In the description of the table in FIG. 3, the situation of the absolute time T and the situation of the motion M may be directly proportional, but by adjusting this relationship freely, the operation interval can be adjusted. For example, in a golf swing, when a club is swung down, it feels as if it is accelerating constantly or uniformly, but the actual speed of the club head is not a simple acceleration motion. Therefore, by appropriately adjusting the relationship between the time T and the motion M, a sense of unity with the avatar can be expressed.

Similarly, by adjusting the proportional relationship between the analog input displacement X and the absolute time T, rough operation and detailed operation can be handled continuously. Since human sensation is logarithmic, as can be clearly seen in hearing, adjustment of this part is a very important factor in controlling movement.

In step #C, an output display is performed. From the motion data file 16 corresponding to the 3D data created in step #B and the image data file 17 of the avatar (virtual person), one frame (1/60 sec: refresh rate of the display device) in a series of operations is determined. It is created and output to the display device 12.

Here, the motion data file 16 and the avatar image data file 17 will be described. A method of wrapping a certain object in an arbitrary triangle plane and fixing the vertex coordinates of the triangle in a three-dimensional (xyz) space to specify the shape and the absolute position of the substance in the virtual space is called a polygon model. I have. When this is applied to the human body, since the movement is involved, the vertex coordinate group of each polygon at a certain absolute time and the vertex coordinate group after the movement in the virtual space one fixed time later are recorded. Display device 1
If this coordinate group is recorded for each frame of 2, the 3D motion animation can be performed by continuously reproducing the data. In the present embodiment, the motion data file 16 corresponds to a series of vertex coordinate groups corresponding to the table in FIG. 3, and the image data file 17 corresponds to texture data for reproducing the data in a virtual space.

In step #D, a situation analysis is performed. The meaning of the analog input absolute time (corresponding in step #B) is analyzed, and if it is a singular point (step #E: YES), the process proceeds to the next control (if necessary, If the input processing is interrupted or the processing branches to another processing program (step #E: NO), the flow returns to step #A for analog data input.

This control program is associated with a series of actions of a person or the like, and is basically made up of the fastest possible repetition routine. For example, a loop time corresponding to a refresh rate (video rewriting speed) of a video output device such as a TV monitor may be set.

For example, in a shot scene of a golf game, the position at which the golf club is swung up is divided into 128 equal parts from the reference stance to the highest position, and the analog input device 11 which can perform analog input from the reference point X0 to the maximum input point Xmax.
Synchronize with the 128 equally divided positions up to. By operating the analog input device 11, the amount of change (displacement) Xi from the reference point X0 is measured at intervals of 1/60 second (one frame time), and the golf ball corresponding to the displacement Xi is displayed on the display device 12. The shot posture Yi is displayed every frame time. Thereby, the person who operates the analog input device 11 can see that the avatar is exercising completely in synchronization with the input operation of the player (self).

Various modifications and changes are possible without being limited to the above-described embodiment, and these are also within the equivalent scope of the present invention. In the present embodiment, the video game machine has been described as an example. However, the present invention can be similarly applied to a virtual reality reproducing apparatus that requires another graphical user interface in which the sense of unity with an avatar is very important. For example, in addition to a video game machine, the present invention can be applied to a simulator, CAD, and the like, and a case where the present invention is used in the field of robotics such as a machine tool (computer control) is also included in the present invention.

Although the image to be reproduced has been described by taking a character in a video game as an example, the present invention can be applied to the case where the image to be reproduced is an anthropomorphic object.

[0027]

As described above, the actual human movement involves trial and error repetitive movements and adjustment of the operation speed, and these expressions cannot be expressed by the conventional progress control method. However, according to the present invention, since the input operation of the operator (player or the like) of the analog input means is directly reflected on the operation of the image to be reproduced (avatar or the like), a sense of incongruity occurs between the input feeling and the result. Absent.

According to the present invention, time and displacement in the physical space are reversibly associated with each other.
Since the time can be manipulated, it is possible to control the operation going back in time and the speed of progress of the time, and as a result, the operator can perform trial and error and speed adjustment of the operation. Therefore, when applied to video game machines,
There is an effect that it is possible to bring an unprecedented sense of unity to the operating game player and the avatar who is a character in the game.
