Abstract

PROBLEM TO BE SOLVED: To attain the real performance by recognizing the contents of instructions based on the contact frequency and the contact impact force caused between an input device and an instruction input measurement means and communicating these recognized contents to a virtual expression system. SOLUTION: A virtual world expression system 200 of a virtual space generation/motion ride system generates the images, the operations of a motion ride device, the sounds and the control rules of peripheral devices. An input system 100 inputs the instructions, and an output system 300 visualizes the images generated by the system 200 and turns the sounds produced by the system 200 into the audible sounds. At the same time, the system 300 drives the motion ride device and operates the peripheral devices. In such a way, a virtual world is created in the system 200. In other words, the contact frequency and the contact impact force which are caused between an input device and an instruction input measurement device are detected as the input of instructions. Then the contents of instructions are recognized, based on a prescribed standard of evaluation, and these contents are communicated to the system 200.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a virtual space generation / motion ride system, and more particularly to constructing a virtual world including at least one object and an environment in which the object exists, and at least a part of the virtual world. The present invention relates to a virtual space generation / motion ride system that generates an image to be visually displayed and further generates a motion of a motion ride device corresponding to a motion of an object to build a virtual space.

[0002]

2. Description of the Related Art A virtual space generation device for generating and displaying an image is a device for generating and displaying an image according to various events occurring in a virtual world including an object, and an event occurring in the real world indicates an object. A device that acts on the virtual world to change the virtual world, generates and displays an image of the virtual world, and an event that occurred in the real world is generated and displayed as an event in the virtual world that models the real world. There is a device to do.
For example, as these devices, a virtual environment generation device disclosed in JP-A-6-161477 and a three-dimensional game device disclosed in JP-A-7-8632 can be cited.

In these devices, in order to input data from the real world to the virtual world, an input device for indicating a direction and an input device for touching with a button are used.

On the other hand, in the motion ride device, at least one person (experienced person) is boarded, and the motion ride device is connected to the motion ride device in accordance with a predetermined instruction input, an instruction input from the experience person, and an event occurring in the real world. Is generated, and the drive device is actuated by the control input generated by the operation instruction, and operates in at least one degree of freedom direction.

This is used as, for example, a virtual reality system, an amusement system, and a disaster simulator together with the above-mentioned virtual space generation device.

[0006]

However, depending on the object in the virtual world, the input device such as the direction indication and button like the conventional motion ride device may not be suitable as the instruction input means. For example, when the object is a horse and a horse riding experience is simulated, the input device such as the direction instruction and the button as described above is far from the instruction input means to the horse in the real world, and therefore the experience person is a virtual person. It is difficult to experience such a real feeling.

[0007] A first object of the present invention is to allow an experience person to input an instruction in a virtual world depending on the form of an object.
It is to provide an instruction input means capable of producing a more realistic effect.

Further, in the virtual reality system so far, in the virtual world to which the object belongs,
There is no means for the object to autonomously set its own state in response to the environment of the virtual world, regardless of the instruction input to the object from outside the virtual world. For example, when the object is a horse and there is an obstacle ahead while the vehicle is running, the horse does not avoid the obstacle without the user inputting an instruction for avoiding the obstacle.

A second object of the present invention is to provide a state setting means for an object to autonomously set its own state corresponding to the environment of the virtual world.

Further, in the conventional virtual reality system, the object in the virtual world is set with the shape and the movement of the object as desired by the user according to the information regarding the shape and the movement set in advance in the system. Is not easy. The third object of the present invention relates to the shape and dynamics of objects in the virtual world.
It is to provide an instruction input means that can be freely set by an experienced person or a third party other than the experienced person.

Further, in the conventional virtual reality system, it is impossible to display an image desired by a person other than the experiencer, and only an image depicting the virtual world can be observed from a given viewpoint. . For example,
The image displayed by the HMD (head mounted display) can be observed only by the experienced person who wears the HMD.

[0012] A fourth object of the present invention is to provide a third object other than that of an experienced person.
Another object of the present invention is to provide an instruction input setting means that enables a person to instruct and select a desired image from a desired viewpoint.

Further, in a horse riding experience in the real world, the experience person is affected by not only the movement of the object but also the surrounding environment such as temperature, weather and wind. It is not easy to produce reality in synchronization with the image of the virtual world generated by the device to improve the reality.

A fifth object of the present invention is to provide a peripheral device that expresses the environment around the object based on the environment attribute information of the virtual world including the object, and improve the reality of the experience person.

[0015]

A first object of the present invention is to provide an instruction input system in which at least a part of a surface of a motion ride device is contacted between an input device and an instruction input measuring means and an impact force at the time of contact. Is recognized as an instruction input, the content of the instruction is recognized in accordance with a preset evaluation standard, and the instruction content is communicated to the virtual world representation system by the first aspect. You can

The second object is, in the first aspect, provided with a virtual world database for accumulating information about states of objects included in the virtual world, and according to the information previously accumulated in the virtual world database. Can be achieved by the second aspect, which comprises a state setting means for setting the state of the object included in.

Further, the third object is that in the second aspect, the object further included in the virtual world in advance,
This can be achieved by the third aspect including an instruction input means capable of accumulating information about the state of the environment in the virtual world in the virtual world database.

The fourth object is, in the third aspect, an object included in the virtual world, a viewpoint when an image of the virtual world is displayed, and at least a part of a state of an environment in the virtual world. Can be achieved in advance by the fourth aspect, and further has an instruction input setting means for changing at least a part of the above-mentioned state during system operation.

A fifth object of the present invention is, in the virtual world expression system according to the fourth aspect, to generate a control law for a blower installed in a motion ride device based on information stored in the virtual world database. This can be achieved by the fifth aspect, which has a blower control means and is provided with a motion generation means for generating a motion of the motion ride device based on the information accumulated in the virtual world database.

And an input system 100 for inputting instructions, and an output system 300 generated by the virtual world representation system 200 for visualizing images, making sounds audible, driving a motion ride device, and driving peripheral devices. . A virtual world is generated in the virtual world representation system 200.

An example of the virtual world is shown in FIG. The virtual world is composed of objects, environments, and cameras.

An object is a subject of motion in the virtual world. For example, it may be any of organic substances such as humans, animals and plants, structures such as vehicles and buildings, and creations that do not exist in the real world. Also, a plurality of these objects may exist in the same virtual world. In FIG. 2, three horses are shown as objects.

The environment is a space where the above objects exist. For example, the space, the earth, the sky, forests, cities, the inside of buildings, and the like. The environment may be completely imaginary, it is not necessary to follow the physical laws of the real world, and a plurality of these environments may exist in the same virtual world. In FIG. 2, as the environment, the sky and the space formed by the racetrack are shown. The environment can also include the concept of time. For example, there are changes over time and seasons.

The camera is a virtual device for designating a part or the whole area of the object when visualizing an image of one or both of the object and the environment in the virtual world. FIG. 3 shows an example of camera settings. FIG.
In the example, five types of cameras, that is, a production camera, a jockey viewpoint camera, an object viewpoint camera, an object center camera, and an object tracking camera are set.

The production camera has a fixed position on the virtual world coordinates centered on the origin 0 in the figure, and can change only the photographing direction. Other cameras change the position and the shooting direction in the virtual world in response to the change in the position of the object.

The jockey viewpoint camera designates a virtual world image observed from the viewpoint of the experience person, and the position and photographing direction in the virtual world are determined by the camera position input from the HMD.

The object viewpoint camera is located at the viewpoint position of the object (the position of the horse's eyes in the example of the figure) and specifies the virtual world in the traveling direction of the object.

The object center camera is a camera set at a position at a constant distance from the center position of the object, and the viewpoint is always set in the object center direction.

The object tracking camera designates the center direction of the object at time t from the center position of the object at time (t-dt), which is past by time dt.

In this system, a third party other than the experienced person can specify any one of the above cameras using the display switching terminal and select a desired virtual world image.

In the present invention, it is possible to output not only images but also sounds. Sound is the background sound generated by the state of the environment, the sound emitted by the object itself,
Sounds generated by the interaction between objects and the environment, voices of commentators, music, narration for explaining the virtual world, guide messages that convey operating methods, and the like. The sound emitted by the object itself includes, for example, dialogue,
There are calls, noses, and response sounds when responding to instructions to the object. The sound generated by the interaction between the object and the environment includes an impact sound when the object acts on the environment, for example, an impact sound when the horse kicks the ground.

Next, the outline of each part of the present invention will be described.

The virtual world representation system 200 is a state setting means for setting the states of objects, environments, and cameras facing them included in the virtual world.
210 and a virtual world database 220 that stores information on the virtual world set by the state setting means. In addition to these, the virtual world representation system 200 is based on the information of the virtual world database 220 and the incidental effect generation means 230 that generates an effect incidentally caused by the interaction between the object and the environment based on the information of the virtual world database 220. Sound generating means 24 for generating sound
0, image generation means 250 for generating an image of the virtual world based on the information in the virtual world database 220, peripheral equipment control means 260 for generating a control law for the peripheral equipment based on the information in the virtual world database 220, virtual world database 220 And a motion generation unit 270 that generates a motion of the motion ride device based on the information of 1.

For example, when the state setting means 210 receives data transmitted from the instruction input system 100, the state setting means 210 interprets the content of the data and the data is an object,
It is determined whether the object is a camera or an environment, and if the data is related to the object, the object setting unit 211 causes the object attribute information for setting the object in a specific state, for example, the type of position and movement. If the data is related to camera settings, the camera setting unit 212 sets and outputs the position and direction of the camera, and if the data is related to environment settings. , Environment setting section 2
The state of the environment such as background, time and weather is set and output by 13.

The object setting section 211 sets and changes the information of the object for describing the state that each object should take. This information can be set to be updated when a new setting is made and when the set state is executed. However, if the newly set state does not interfere with the execution of the previously set state, then the new state setting will not be compared to the previously set state. You may make it exist together. On the contrary, when the newly set state interferes with the execution of the previously set states, the state of the object is updated to the newly set state.

The camera setting unit 212 sets the camera position and the camera direction when observing the virtual world. As described above, this camera position is set by the position in the three-dimensional space consisting of the xyz axes forming the coordinate system of the virtual world and the direction (θ _xc , θ _yc , θ _zc ) at that position. .

The environment setting unit 213 has a place, background, time,
Set the weather etc.

All the information output by the state setting means 210 is stored in the virtual world database 220.

The camera information is information on the camera position and the direction vector, as described above.

The environment information includes time information representing the time of the virtual world, information representing a natural phenomenon in the environment, information representing a change with time of the environment, and what kind of image the environment should be represented in accordance with the information. The image change information to be shown and the information about the accompanying effect can be given. The information on natural phenomena includes, for example, information on phenomena that change from moment to moment such as weather, information on rare phenomena such as earthquakes, seasonal changes, daily changes, etc.
There is information indicating the periodicity. The information about the incidental effect includes a change pattern regarding a local change of the environment that should occur with the movement of the object, an image element for causing the local change, a physical law for generating the incidental effect, and the like. As the image element, basic image data for generating shrapnel, dirt and the like as shown in FIG. 4 can be mentioned. As the physical law, for example, a motion equation related to falling can be cited.

The object attribute information is data for indicating the basic form and motion of each object, for example, form data such as outer shape and skeleton, motion data indicating the movement of each part during motion, and the property of the object. For example, there are weight, color, personality, and change information over time. Examples of the temporal change information include a decrease in the ability of the object. Specifically, there are information for updating the ability of an object in response to a change with time, information for defining matters that change with it, and the like. Items that change as the ability of the object decreases include, for example, the speed of the object.

As the morphological data, for example, as shown in FIG.
As shown in FIG. 6A, shape data in which the outer surface of an object is approximated by a polygon is represented, and as shown in FIG. 5B, skeleton data that defines the skeleton of the object. As shown in FIG. 6B, the shape data includes the definitions of the vertices that make up each of the polygons p1, p2, p3, p4 ... And the coordinates of each vertex expressed in the local coordinate system of the object. , The data representing the relation rate with respect to the movement of each bone constituting the skeleton of each vertex.

Regarding the motion data, as shown in FIG. 7, there is information indicating the time change of the angle of each bone (skeleton 1, ..., Skeleton n) of the skeleton with respect to the movement of the object.

The incidental effect generating means 230 receives the object information of the virtual world database 220 and the environment information, and generates a change caused by the movement of the object to a part of the environment. For example, when the object is a horse, when the horse runs on the dirt ground, the horse's foot kicks the ground, so that the stones on the ground are flipped up, and dust is generated.

The sound generation means 240 generates sound information such as a sound emitted by the object, a background sound, narration, a guide message, and music in accordance with the state of the object. As for sounds, narrations, and guide messages generated by objects, for example, phoneme piece data generated in advance by recording or synthesizing, speech, emotion expression sound, response sound,
Data specifying a combination of phoneme pieces that should generate a sound according to the expression such as narration and guide message is stored in the library. For the background sound and music, sounds existing in the environment can be recorded in advance, stored as a sound library, and reproduced as necessary. If the position of the sound source is related, the data indicating the position is also recorded. These may be built in the virtual world database 220.

The image generating means 250 uses the respective information regarding the object, environment and incidental effect, and
The state of the virtual world in the near future is sought, images are generated momentarily based on the sought state, and they are combined. The images are sequentially generated to form a moving image as a whole. In addition,
You may make it form a stop image. Image generation means 2
50 obtains the near future state of the object based on the object information stored in the virtual world database 220. Then, an image of the object is generated by referring to this near future information and the camera attribute information.
This includes images with HMD output. Further, an image of the environment is generated by referring to the camera setting information of the virtual world database 220 for the state of the next environment specified by the environment information of the virtual world database 220. Further, for the incidental effect generated by the incidental effect generating means 230, an image is generated by referring to the camera information.

The motion generating means 260 obtains the near future state of the object based on the object information and the environment information of the virtual world database 220, and based on the obtained state, the control rule regarding the motion of the motion ride device is added momentarily. To generate.

The peripheral device control means 270 controls the peripheral device based on the object information of the virtual world database 220 and the environment information. For example, when controlling a blower as a peripheral device, the information about the set speed of the object is referred to as the object attribute information, and the temperature, air volume, humidity, etc. of the air sent from the blower are determined by the information such as weather and temperature as the environmental attribute information. Adjust.

Do one.

In the instruction input process, the whip input of each motion ride device previously input to the virtual world database,
Information regarding the input of the reins is extracted, and the instruction content is recognized from these input patterns. Subsequent work is performed on the work area 616.

FIG. 20 shows an outline of macro processing. In the macro operation processing, first, the possibility of collision in the virtual world is judged. Collision probability depends on the distance between mutual objects,
Determine using relative speed. When there is a possibility of collision, the traveling direction is changed by a rotation process in order to avoid the collision. If there is no possibility of collision, check which instruction is set for the object. If nothing is entered here, the default instructions can be applied. Then, a traveling process that is a process related to the instruction is performed. The traveling processing includes deceleration, acceleration, straight ahead, jump and the like.

The traveling processing will be described with reference to FIG. FIG. 21 performs processing relating to the running motion of the horse, which is an object. In this example, the target traveling speed of the horse is given. And always adjust the kicking speed of the horse. The strength and cycle of kicking are decided at each initial timing of kicking. Normal kicking (strength 1, cycle T)
Then, assuming that the speed becomes V0 and the target speed is V,
The correction coefficient c is calculated. At this time, the cycle is T / c, the strength is C
And A single kicking motion is obtained by referring to the motion basic data. This is corrected according to strength and cycle. θ is the joint angle.

In FIG. 21, the state setting means determines whether or not the start of kicking t = 0, or t> T / c, and if so, calculates a correction coefficient for kicking from the desired speed. . Then, the elapsed time is cleared. afterwards,
Normalize the time. That is, t '= t / c.
Next, the running motion is extracted for each joint.
This running motion is given by the time change of the angle of each part of the skeleton, as shown in FIG. Therefore, this running motion is corrected by changing the angle of the joint. As a result, the traveling state changes. In this state,
Set the acceleration. This acceleration is obtained by multiplying the initial acceleration a0 by the square of the correction coefficient c. Update the time here. Then, it is checked whether or not there is a rotation instruction input, and if there is rotation input, rotation processing is carried out.

The rotation process will be described with reference to FIG.

The horse, which is an object, is given a target angle of direction change and the time required for it. It is necessary to bend the body to change direction. The function of bending the body is decided by referring to the basic data of motion. In FIG. 22, first, it is checked whether the start of rotation is t = 0. If applicable, the rotation time T is set and the rotation angles α0, β0, γ0 are set. After that, the elapsed time t is cleared. Next, the rotational motion is taken out. Here, the rotational motion is a function of the time change of the angle of each part of the skeleton, as shown in FIG.
Here, as in the case of traveling, the angle of the joint is changed to correct the direction of the object. Then, the time is updated.

In the motion processing, the motion of the horse is described according to the physical laws in the environment. Specifically, the position of the horse is changed according to the equation of motion. In addition, along with this, information for acoustic processing and an after-mentioned ancillary effect is output. FIG.
In 3, the driving force f by kicking for changing the speed is calculated using the correction coefficient c when the driving force in the normal state is f0.
