BACKGROUND OF THE INVENTION
The present invention relates to a virtual reality playback device such as a video game machine that uses an analog input device to control the operation of a playback target image such as a character (virtual self; avatar) and a program thereof.
[0002]
[Prior art]
Conventionally, the progress control of a video game machine is controlled by the game player by entering the start timing of a series of actions (sequence) as a unit, or by replacing them with another action unit. (First progress control method).
[0003]
There is also a method of instructing to input a minute time difference amount between the moving direction and the amount of the moving target (second progress control method). In this progress control method, the result of the control appears as an integrated value of the change in the target moving speed and moving direction within a certain time. For example, it has been used in conventional car racing games, ski games, action games that move in a maze, and the like.
[0004]
[Problems to be solved by the invention]
However, the first progress control method is an indirect operation such as starting with the “first button” and stopping with the “second button”, and the sense and operation are uncomfortable.
[0005]
Further, the second progress control method operates in a preset operation time, and the progress direction of the operation time is limited to the same direction as the real time.
[0006]
As described above, it is difficult to say that the conventional progress control method reproduces an intuitive operation when the displayed target is a person and the movement is an important element for the subject to be expressed.
[0007]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings.
FIG. 1 is a block diagram showing an embodiment of a virtual reality playback device and its program according to the present invention, and FIG. 2 is a diagram for explaining a display operation of the virtual reality playback device according to this embodiment.
The virtual reality playback device 10 of the present embodiment is realized by a video game machine such as a personal computer or a TV game machine, for example, 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 unit 13 including a CPU, RAM, ROM, etc. for controlling the progress of the game. ing.
[0014]
Further, as shown in FIG. 2, the arithmetic processing device 13 stores a plurality of motion images Yi obtained by subdividing a series of motions of the game target image every minute time, and each motion image Yi is stored in an analog input device. The game progress is controlled so as to be played back on the display device 12 in association with the 11 displacements Xi.
Specifically, the arithmetic processing unit 13 stores 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 in the storage means. The progress is controlled according to the flowchart described later.
[0015]
Next, the procedure of the control program of the virtual reality playback device of this embodiment will be described.
In step #A, an analog data input operation is executed. That is, the displacement amount from the reference point of the analog input device 11 to the input operation position is acquired.
[0016]
In Step #B, video output data creation is executed. 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 that is a time fragment of the motion Mi assumed from the time: motion data correspondence table 15 is created.
[0017]
FIG. 3 is a diagram for explaining the analog input displacement: time correspondence table 14 and the time: motion data correspondence table 15 of the virtual reality reproducing apparatus according to the present embodiment.
In FIG. 3, the respective symbols are as follows.
X is a value such as 0 to 128, and the maximum value (max) varies 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 max value.
M: A serial number is given to the situation of each frame obtained by disassembling a series of operations in unit time.
D: 3D polygon data group and texture data of the motion.
[0018]
The table in FIG. 3 shows the two tables together for easy understanding. The item of absolute time T is used for parameter delivery.
Here, the reason why an absolute time T item is inserted between the analog input displacement X and the resulting motion data D will be described below.
In the description of the table of FIG. 3, the situation of the absolute time T and the motion M may be directly proportional, but the operation interval can be adjusted by freely adjusting this relationship. For example, in a golf swing, when a club is swung down, it feels as if it is constantly or uniformly accelerating as a sensation, but the actual club head speed is not a simple acceleration motion. Therefore, by appropriately adjusting the relationship between the time T and the motion M, it is possible to express a sense of unity with the avatar.
[0019]
Similarly, by adjusting the proportional relationship between the analog input displacement X and the absolute time T, it is possible to handle rough operations and detailed operations continuously. Since the human sense is logarithmic as seen in the auditory sense, the adjustment of this part is an extremely important factor in controlling the movement.
[0020]
In step #C, 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 seconds: display device refresh rate) in a series of operations. Create and output to display device 12.
[0021]
Here, the motion data file 16 and the avatar image data file 17 will be described. A method of specifying the shape and absolute position of a substance in virtual space by enclosing an object in an arbitrary triangle plane and fixing the vertex coordinates of the triangle in a three-dimensional (xyz) space is called a polygon model. Yes.
When this is applied to a human body, since motion is involved, a vertex coordinate group of each polygon at a certain absolute time and each vertex coordinate group after moving in a virtual space after a fixed time are recorded. If this coordinate group is recorded for each frame of the display device 12, 3D motion animation can be performed by continuously reproducing this data.
In the present embodiment, the motion data file 16 corresponds to a series of vertex coordinate groups corresponding to the table of FIG. 3, and the image data file 17 corresponds to texture data or the like for reproducing the data in a virtual space.
[0022]
In step #D, situation analysis is performed. Analyzing the meaning of the analog input absolute time (corresponding to step #B), and if it is a singular point (step #E: YES), shift to the next control (if necessary, If the input process is interrupted or branched to another processing program, etc., otherwise (step #E: NO), the process returns to the analog data input at step #A.
[0023]
This control program is associated with a series of actions such as a person, and is basically made up of the fastest repetitive routine possible. For example, a loop time corresponding to the refresh rate (video rewriting speed) of a video output device such as a TV monitor may be set.
[0024]
For example, in a shot scene of a golf game, the position where the golf club is raised is divided into 128 equal parts from the reference stance to the highest position, and the position 128 from the reference point X0 to the maximum input point Xmax of the analog input device 11 capable of performing analog input Correspond and synchronize with equal positions.
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 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 in complete synchronization with the input operation of the player (self).
[0025]
The present invention is not limited to the embodiment described above, and various modifications and changes are possible, 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, but the present invention can be similarly applied to a virtual reality playback device that requires another graphical user interface in which a sense of unity with an avatar is very important. For example, in addition to video game machines, the present invention can be applied to simulators, CADs, and the like, and is also included in the present invention when used in the field of robot engineering such as machine tools (computer control).
[0026]
Further, although the reproduction target image has been described by taking a video game character as an example, the present invention can also be applied to a case where the target image is anthropomorphic.
[0027]
【The invention's effect】
As described above, the actual human movement involves repeated trial and error movements and adjustment of the operation speed, and these expressions cannot be expressed by the conventional progress control method. According to this, the input operation of the operator (player, etc.) of the analog input means is directly reflected in the operation of the reproduction target image (avatar, etc.), so that there is no sense of incongruity between the input feeling and the result.
[0028]
In addition, according to the present invention, time and physical space displacement are reversibly associated with each other, and the time can be manipulated by adjusting the displacement. The speed can be controlled, and as a result, the operator can perform trial and error of operation and speed adjustment.
Therefore, when applied to a video game machine, there is an effect that it is possible to bring an unprecedented sense of unity to an operated game player and an avatar that is a character in the game.
