Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motion determination device, a motion determination method, and a game device and a simulation device using the motion determination device, in which a player inputs a motion by a stepping motion.

[0002]

BACKGROUND ART Recently, a player rides on a board imitating a ski and a virtual 3
A three-dimensional ski game device has been proposed in which virtual skiing is performed in a three-dimensional space and the state is displayed on a display (Japanese Patent Laid-Open No. 3-212263). However, in such a game device, the information that can be input from the board is limited to the operation of the ski, etc., and it has not been possible to determine a complicated motion state such as walking, jumping or squatting. Conventionally, there has been no game device in which the player inputs the player's motion state such as walking, jumping, squatting, or the posture by actually performing the operation on the board.

On the other hand, in a game device that performs boxing or martial arts on the game screen, input is performed by operating buttons, levers, or the like. In such a game device, the player must input the movement of the game character on the screen by operating a button or lever.

For this reason, it has not been possible to have a simulated experience in which the player actually moves in the space like a game character and fights against an enemy fighter.

Further, since the movement of the game character is operated only by operating the button and lever, the game operation becomes complicated,
Moreover, the movement of the game character is separated from the actual operation, which makes it difficult for beginners to understand the game operation.

Further, the movement of the game character is limited only by the operation of the button and the lever, and the input for expressing the complicated movement of the actual person cannot be performed.

In a game device or the like, if it becomes possible to input the motion of the character on the screen by the motion of the player himself instead of operating the buttons or levers, the actual game operation can be performed without performing a complicated game operation. You can input complex movements of people. Moreover, the player can blend into the game operation without feeling uncomfortable, and can enjoy the game as a whole with the game character.

However, in general, a lot of information is required to judge the actual movement or motion state of the human body, and the calculation for processing the information becomes complicated. For this reason,
In the conventional game device, the player's own movement motion cannot be used for input.

Also in a device for simulating various movements, there is a demand for a simulation device capable of accurately detecting an actual human motion with a simpler configuration and simple arithmetic processing. There was no.

The present invention has been made in view of the above problems, and obtains information for determining the movement and exercise state of a human body with a simple configuration and processes the information by a simple arithmetic process. A motion determination device, a motion determination method, and a game device and a simulation device using the motion determination device.

Here, the movement of the player includes the movement and posture of the player.

According to the first or ninth aspect of the invention, when the player rides on the player placing means and makes a motion, the pressure due to the motion is detected.

In this way, the player can input his / her own motion by riding on the player mounting means and performing the motion to be judged. Therefore, by using a player mounting table or the like equipped with a pressure sensor or the like to detect the pressure, it is possible to obtain information for determining the movement of the human body such as movement or motion with a simple configuration.

Further, it is possible to provide an exercise determination device and an exercise determination method for limiting the exercise to be determined by specifying the exercise content, and processing the information by a simple arithmetic process.

In the determination step, the motion of the player is determined based on the inclination of the virtual plane calculated in the inclination calculation step and the determination condition.

For example, assuming an imaginary plane including each of the support points, this imaginary plane is the XY plane, and the direction in which pressure is applied is Z.
Use the coordinate direction. Then, the inclination of the virtual plane with respect to the horizontal plane is calculated based on the pressure applied to each of the support points.

The inventor of the present application pays attention to the fact that the inclination and the movement of the player are closely related to each other, and based on various experimental results, found a certain pattern in the inclination of the virtual plane obtained by the movement of the player.

Therefore, in the present invention, the determination condition obtained by analyzing the pattern of the inclination of the virtual plane due to the player's movement is set in advance, and the inclination of the virtual plane calculated from the detected pressure, The motion of the player is determined based on the determination condition.

In this way, the concept of the inclination of the virtual plane is introduced, and the inclination of the virtual plane is obtained based on the detected pressure and used for the motion determination, so that the movement and the motion state of the player's body can be accurately determined with a small amount of information. Can be done.

According to a fourth aspect of the present invention, in the third aspect, the first determination condition storage means assumes a reference plane for motion determination in the virtual three-dimensional space, and an outer product determined based on the virtual plane.

According to the fourth aspect of the invention, the judgment condition is set by projecting the outer product vector determined on the basis of the three-dimensional virtual plane onto the reference plane. Here, the outer product vector determined based on the virtual plane is, for example, different 2 determined by two support points when the support points are arranged in the virtual three-dimensional space based on the pressure applied to the support points. It can be calculated using two vectors.

By doing so, it is possible to set a complicated motion determination condition under a simpler condition, and it is possible to reduce the load of the arithmetic processing when performing the determination.

Further, in claim 2, the motion determining means further includes a center of gravity calculating means for calculating a center of gravity of the player based on the pressure applied to the support point detected by the pressure detecting means, and the first determination condition storage The means stores a determination condition for determining which of the exercises to be determined the player's exercise corresponds to, based on the center of gravity, the first determining means includes the center of gravity calculating means.

That is, X and Y, which are the plane coordinates of the three support points, are defined as X and Y coordinates, and the pressure applied to the three support points is defined as the Z coordinate, with the function value using the pressure applied to each support point as a parameter. The barycentric coordinates of the three support points are calculated as

Since the center of gravity and the player's motion have a close relationship, a certain pattern is derived from the relationship by experiment, and the player's motion is judged based on the pattern in the first judgment condition storage means. The determination condition for doing is stored. Then, the first determination means is configured to determine the motion of the player based on the center of gravity calculated by the center of gravity calculation means and the determination condition stored in the first determination condition storage means.

The determination result determined by the motion determination device can be input to a game device, a simulation device, or the like as necessary, and an embodiment in the case of being input to the game device will be described later.

As shown in FIG. 2, the input board 30 is a mounting table on which the player rides, and a step 32 and a step 32.
Pressure sensors 34a, 34 for detecting the pressure applied to the
b and 34c are included.

In step 32, the reference position on which the player rides is displayed as the foot mark 31, and the player stands on the foot mark 31 in step 32 to avoid movements such as avoiding or leaning forwards, backwards, left and right, and jumps. When performed, the three pressure sensors 34a, 34b, 3 arranged on a non-straight line
4c detects the pressure associated with the movement.

The pressure detected by the input board 30 is input to the motion judging section 100 to judge the motion.

The motion judging section 100 functions as a motion judging means for judging the motion performed by the player based on the pressure detected by the input board 30, and the first judging condition storage section 11
0, inclination calculation unit 120, first determination unit 130, pressure transition storage unit 140, second determination condition storage unit 150, second determination unit 1
It is configured to include 60.

Next, the function and action of judging the player's motion based on the input from the input board 30 will be described in detail for the input board 30 and the motion judging section 100.

First, the structure and operation of the input board 30 will be described below.

FIG. 2 shows steps 32 of the input board 30 of this embodiment and pressure sensors 34a, 34b, which are arranged therein, for detecting the pressure applied to the step 32.
It is the figure which showed 34c.

Three pressure sensors 34a, 34b, 34c
Are arranged at the positions corresponding to the vertices of an equilateral triangle and support step 32. When the player rides on the footrest section 31 of the input board 30 and plays, the foot positions fall within the equilateral triangle. Is formed in.

These three pressure sensors 34a, 34b, 3
4c is set so that the detected pressure becomes 0 when no one is on the input board 30. When the player gets on the input board 30, the three pressure sensors 34a, 34
b and 34c detect the pressure based on the weight of the player. When the player stands still on the input board 30, the total pressure detected by the three pressure sensors 34a, 34b, 34c becomes equal to the weight of the player. The player jumps or crouches on the input board 30,
When a motion for tilting the state or other motion such as a change in posture is performed, the pressure values detected by the three pressure sensors 34a, 34b, 34c change variously.

The three pressure sensors 34a, 34b, 34c used in the present embodiment include a capacitor composed of two conductive plates which are separated from each other by the application of force, and this capacitor is used as an astable multivibrator circuit. It has a configuration incorporated in. The output frequency of the astable multivibrator circuit changes due to the capacitance change of the capacitor, and the pressure is detected by the change of the frequency. Specifically, a change in pressure of 0 kg to 70 kg is output as a clock signal of about 20 KHz to 14 KHz.

A concrete block diagram of such an input board 30 is shown in FIG. 3A, and a concrete circuit diagram of the interface is shown in FIG.
(B). As shown in FIG. 3A, the input board 30
Is formed by including three pressure sensors 34a, 34b, 34c, an interface 35 for converting a change in frequency output from each sensor into a clock signal, and a power supply 36.

Further, as shown in FIG. 3B, the interface 35 includes a changeover switch 33 for switching the input from each sensor, a reference clock circuit 42 for outputting a reference clock, and a reference per pulse output by the sensor. 8-bit binary counter 37 that counts the number of clocks, latch circuit 38 that latches the output of 8-bit binary counter 37, and 8-bit binary counter 37
And a controller 39 for controlling the operation of the latch circuit 38
It is comprised including.

Then, by connecting the interface 35 to the I / O port 92 of the motion determining unit 100, the motion determining unit 100 allows the sensors 34a, 34b,
Information on the pressure detected by 34c can be obtained.

Next, detailed functions and actions of each part of the motion determining unit 100 and the principle of motion determination will be described in detail.

When the player rides on the input board 30 and makes a motion, the pressure sensors 34a, 3 provided at the three support points
4b and 34c detect the pressure. For example, when the player leans to the right on the board 30, the pressure detected by the pressure sensor 34a increases and the pressure detected by the pressure sensor 34b decreases.
When the player jumps, the pressure at each point increases due to the stepping force of the player immediately before the jump starts, and the force is not applied to the board during the jump, so the pressure value at each point becomes zero. In this way, the pressure value at each point changes variously according to the player's motion.

The inventor of the present application has a close relationship between the detected pressure and the motion of the player. If the motion to be judged is limited, which of the motions of the player corresponds to the motion of the player based on the pressure. I found that I can identify. Therefore, a constant pattern was found in the player's exercise, the pressure value at each point, and the change in the data by an experiment for measuring the pressure value at each point and the change in the exercise to be judged. Therefore, in the exercise determination apparatus of the present embodiment, the limited determination target exercise and the determination condition calculated for the exercise from the pattern are stored in the first determination condition storage unit 110 of the exercise determination unit 100 and the second determination. The condition storage unit 150 is configured to be stored in advance and to judge the player's exercise based on the judgment condition.

Specifically, in order to specify the player's forward, backward, leftward and rightward movements, the necessary judgment condition is to specify in the first judgment condition storage unit 110 a more detailed motion such as squatting or jumping. In addition, necessary determination conditions are stored in the second determination condition storage unit 150.

For the former determination, the inclination of the virtual board, which will be described later, is used, and for the latter determination, the former determination result and the temporal change of the pressure value (hereinafter referred to as pressure value transition) are used.

That is, in the case of making the former determination, the inclination calculating section 120 calculates the inclination of the virtual board based on the pressure value detected by the input board 30, and the first determining section 1
The reference numeral 30 is formed to judge the player's movement based on the judgment condition stored in the first judgment condition storage unit 110 and the inclination of the virtual board.

When making the latter determination, the pressure transition storage section 140 stores the transition of the pressure value due to the player's exercise. Next, the second determination unit 160 uses the first determination unit 13
The movement of the player is determined based on the determination result of 0, the determination condition stored in the second determination condition storage unit 150, and the transition of the pressure value.

The relationship between the inclination and transition of the pressure value of the virtual board and the movement of the player will be described in detail later. First, the function of the inclination calculator 120 to calculate the inclination of the virtual board will be described in detail. .

The inclination calculating unit 120 sets the plane coordinates x and y of the three support points to the x and y coordinates, and sets the pressure applied to the three support points to the z coordinate (hereinafter referred to as a virtual board). It is configured to calculate a parameter indicating the inclination with respect to the horizontal plane (xy plane).

The method of calculating the parameter indicating the inclination of the virtual board performed by the inclination calculator 120 will be described with reference to FIGS.
It will be described based on.

In the xy plan view, the plane coordinates of three support points, which are horizontal positions of b and 34c, are x and y coordinates, and the detected pressure values of the sensors at the three support points are z coordinates. When the pressure is 0, the sensors 34a, 34b and 34c are x
It is assumed to be on the y plane, and the center of gravity at this time is the origin.

Here, the plane including the three points ABC is α,
^'The plane containing the ^alpha' 3 points A ^'B' C When, this plane alpha ^'
Is a virtual plane including a virtual board. This virtual plane α ^'
Has various slopes depending on the pressure value output from each sensor. Since this tilt is closely related to the player's motion as described later, the player's motion can be determined based on this tilt.

[0079] The inclination calculating unit 120 of the present embodiment, seeking a cross product vector of C ^'A' vector and C ^'B' vector C ^'vector to quantify this inclination. C ^'A

[0080] Since the C ^'vector three points ^A' perpendicular to the imaginary plane containing the B ^'C', and the normal vector μ virtual plane shown in FIG. 5 (A), that direction is equal. The C ^'vectors, as shown in FIG. 5 (B), when projected onto the xy plane at the origin as the starting point, ^C' endpoint of the vector is projected to a point E (Cx, Cy, 0) . In this embodiment,
The y-axis direction is the front-back direction and the x-axis direction is the left-right direction.
The vector is used as a parameter indicating the inclination of the virtual board.

Next, the pressure transition storage section 140 and the second determination section 160 will be described.

The pressure transition storage unit 140 includes the input board 30.
It is configured to store the pressure value of each point inputted from the above and the pressure value applied vertically to the virtual board from the pressure value of each point for a given time. As described above, the second determination condition storage unit 150 stores the condition for determining the movement of the player based on the transition of the pressure value. Therefore, the second determination unit 160 determines the pressure transition based on this determination condition. Storage unit 1
The movement of the player is determined from the transition of the pressure value stored in 40.

A method of calculating the pressure value applied vertically to the virtual board will be described with reference to FIG.

In the pressure transition storage section 140 of this embodiment, C
In order to reduce the load of PU calculation, the pressure value applied to the virtual board is calculated by the following area calculation.

[0085] A of FIG. 6 ^{', B',} C ^'represents the same, each pressure sensor 34a, 34b, 34c virtual position of FIG. 4 (B). A ^″ , B ^″ , and C ^″ represent the output values of the pressure sensors 34a, 34b, and 34c at points A ^′ ,
B ^{', C'} X-coordinate of a point obtained crowded added to the Y coordinate.

That is, A ^' (x _' 1, y _' 1, z _' 1),

3), z _′ 1, z _′ 2 and z _′ 3 are output values of the pressure sensors 34a, 34b and 34c, respectively. Therefore, the above respective values are obtained by the following equations.

X _″ 1 = x _′ 1 + z _′ 1 y _″ 1 = y _′ 1 + z _′ 1 z _″ 1 = z _′ 1 x _″ 2 = x _′ 2 + z _′ 2 y _{″ 2 = y '2 + z'} 2 z '' 2 = z '2 x''3 = x' 3 + z '3 y''3 = y' 3 + z '3 z''3 = z' 3 this Based on each value obtained in this way, the triangle A ^″ B ^″
The area of C ^″ is calculated and the value is used as the pressure value applied to the virtual board.

The pressure sensors 34a, 34b, 34c
Even if the player's exercise is the same, the pressure value detected by will naturally differ if the player's weight is different.
The pressure exerted on the board by the player's exercise is proportional to the player's weight. Therefore, in this embodiment, the determination condition is set by the model weight value, and the inclination calculation unit 120 and the pressure transition storage unit 140 set the pressure values detected by the pressure sensors 34a, 34b, 34c based on the player's weight. It is corrected as follows. The weight of the player is determined by the detected pressure value of the player in the stationary state.

Assuming that the model weight value is W1, the player weight value is W2, and the detected values of the pressure sensors are Sa, Sb, and Sc, the correction values Sa ^' , Sb ^' , and Sc ^' are Sa ^' = Sa. × W1 ÷ W2 Sb ^′ = Sb × W1 ÷ W2 Sc ^′ = Sc × W1 ÷ W2

Thus, in this embodiment, each pressure sensor 3
Since the detected values of 4a, 34b, and 34c are corrected as described above, the parameter representing the inclination of the virtual plane and the pressure value applied perpendicularly to the virtual plane are calculated to determine the player's motion. Regardless of the weight of the player, the player's exercise can be determined according to a preset determination condition.

By the way, what is important for recognizing the movement in this way is that the obtained information and the expected movement are not linked one-to-one. That is, there is a plurality of motions that can be expected from the obtained information, and how to determine which one corresponds to the problem becomes a problem. The exercise determination unit 100 according to the present embodiment solves the above problem by specifying the exercise to be determined according to the exercise content to be determined in advance, and this is also an important point of the present invention.

For example, when surfing and boxing exercises are assumed, the same sensor output is obtained for the movement to turn right by the surfboard and the exercise for avoiding punching to the right. Therefore, the exercise of the player can be accurately determined by specifying the exercise to be determined in advance as either one of various exercises in surfing or various exercises in boxing. In this way, by specifying the type of exercise to be determined, the obtained information and the expected exercise can be linked one-to-one, and the player's exercise can be accurately determined with limited information. .

Therefore, by examining the relationship between the sensor output and the player's exercise according to the content of the exercise, the player's exercise can be determined more accurately.

The examples given in FIGS. 7, 8 and 9 are graphs of the experimental results in which the inclination of the virtual board and the transition of the pressure value are measured on the assumption of a martial art such as boxing and the pattern property is examined. Is.

FIGS. 7A, 7B and 7C are graphs showing the time transition of the correction values Sa, Sb and Sc of the pressure values detected by the pressure sensors 34a, 34b and 34c. FIG. 7D is a graph showing the temporal transition of the pressure value Sd applied to the virtual board in the vertical direction.

In these graphs, the horizontal axis represents time, and the vertical axis represents the output value of each sensor when the player stands on the input board 30 and stands still (motion determination of the present embodiment). In the device, the output waveform of each sensor is corrected based on the weight of the player). Therefore, for example, when the player moves from the stationary state to the right, the output waveform of FIG. 7A touches the + direction and the output waveform of FIG. 7B touches the − direction.

FIG. 7E is an xy plan view showing the relationship between the inclination of the virtual board and the movement of the player, and the f vector is a parameter showing the inclination of the virtual board at time t ₁ . That is, the f vector is a vector obtained by projecting the aforementioned outer product vector on the xy plane.

The relationship between the inclination of the virtual board and the player's movement shown in the xy plan view of FIG. 7E will be clarified with reference to FIG.

Similar to FIG. 7E, FIG. 8 is an xy plan view showing the relationship between the inclination of the virtual board and the movement of the player. The vectors fa, fb, fc, fd, and fe of this graph are parameters representing the inclination of the virtual board during various movements of the player, as with the f vector of FIG. 7 (E).

Further, the areas a, b, c, d, and e delimited by the chain line in this graph are (a), (b), (c),
Represented by (d) and (e), each of the regions represents a range peculiar to each movement of the player. That is, the motion of the player can be specified depending on which of the areas the end points of the vectors fa to fe, which are parameters representing the inclination of the virtual board, belong to.

When the end point of the vector generated by the player's movement is within the range of (a) like the fa vector, the change in the inclination of the virtual board is small, and thus the player has a small upper body movement (footwork) or , Is making a vertical movement (squatting, jumping) with respect to the input board 30. At this time, whether it is (footwork) or (squats) or (jump) is determined based on the transition of the pressure value at each point described later.

When the end point of the vector generated by the player's motion is within the range of (b) or (c) like the fb vector or the fc vector, a large change occurs in the lateral direction, so the player I am doing walking or walking to avoid punches left and right. Also in this case, which exercise is performed is determined based on the transition of the pressure value at each point described later.

When the end point of the vector generated by the player's movement is within the range of (e) like the fe vector, the virtual plane is largely tilted backward, so the player avoids punching in the backward direction. I am exercising.
At this time, the magnitude of inclination represents the magnitude of exercise.

When the end point of the vector generated by the player's movement is within the range of (d) like the fd vector, the virtual plane is largely inclined forward, so the player avoids punching in the forward direction. You are exercising (for example, lowering your head). At this time, the magnitude of inclination represents the magnitude of exercise.

In this way, the movement of the player is roughly specified by the inclination of the virtual board. In particular, the inclination to the front, rear, left, and right (a movement to avoid) is almost specified.

Then, how should the exercises other than the avoiding exercises be performed, for example, squatting, jumping, distinguishing footwork, and distinguishing between the avoiding exercise and the walking exercise to the left and right? In the motion determination device of the present embodiment, in such a case, determination is performed by combining the inclination of the virtual board and the transition of the pressure value at each point.

How to determine in such a case will be described with reference to FIGS. 9 and 10. FIG. 9 is a graph when squatting. When the player crouches from the upright state, the inclination of the virtual board is within a certain range, and the pressure is above a certain level. Therefore, the range of the inclination of the virtual board is judged in the range to which the end point of the f vector in FIG. 9 (E) belongs, and the pressure state is determined by the pressure value at each point shown in the graphs of FIGS. 9 (A) to (D). The judgment is based on the transition of.

First, since the end point of the f vector of FIG. 9 (E) is within the range of (a) shown in FIG. 8, the player has a small upper body motion (footwork) or the input board 30.
It is determined that the person is moving vertically (squatting, jumping). At this time, whether it is (footwork) or (squats) or (jump) is (A)-
The determination is made based on the transition of the pressure value at each point shown in the graph of (D). At t2 in FIGS. 9A to 9D, since the pressure value above a certain level is detected, it is determined at this point that the person is in a squatting state.

In general, when the player avoids in a certain direction, the force for stepping is applied in a direction 180 ° opposite to the direction avoided before. This force is a force that increases when the motion is quick. Similarly, when crouching, there is a state in which the inclination becomes smaller and the pressure becomes lower before that.

As described above, the intentional movement always has a force (the direction opposite to the direction in which it is intended to move) for stepping forward. By recognizing this force,
It can be distinguished from intentional movement and unconscious movement or body shaking.

The jump is a state in which the pressure is not applied to the input board 30. On the subsequent landing, on the contrary, the force is applied to the input board 30 after the jump is recognized.
The jump height is obtained from the pressure value (depression) immediately before the jump.

FIG. 10 is a graph in the case of walking motion.
Since the end point of the f vector in FIG. 10 (E) is within the range of (c) shown in FIG. 8, it is determined that the player is performing the avoiding motion to the left or right or the walking motion. At this time, it is determined based on the transition of the pressure value at each point shown in the graphs of (A) to (D) whether it is the avoiding exercise to the left or right or the walking exercise.

When the player makes a walking motion, the operation shown in FIG.
The characteristic waveform diagram in which the pressure alternately moves to the right (A) and the left (B) within the range of the player's weight as shown in FIG. When the user lifts his / her foot, the width of the pressure movement is within a certain range depending on the weight of the occupant, so that it can be distinguished from body shaking or the like. Therefore, if the detected waveform shows such a pattern, it is determined to be a walking motion.

In this way, the motion determination unit 100 of this embodiment specifies the motion to be determined in advance, and then combines the inclination of the virtual board and the transition of the pressure value at each point to determine the motion of the player. Judging.

FIG. 11 is a flow chart showing the procedure when the motion judging unit 100 makes a judgment.

First, the tilt calculator 120 calculates the f vector which is a parameter representing the tilt of the virtual board (step 10). Next, the first determination unit 130 determines which of the regions (a) to (e) of FIG. 8 the f vector belongs to (step 20).

At this time, the area to which the f vector belongs is (d)
Alternatively, in the case of (e), it can be specified that the user is performing the exercise to avoid forward or backward as described above. However, if the area to which the f vector belongs is (a), (b), or (c), there are several possibilities as described above, and the motion cannot be specified. Therefore, it is determined whether the motion can be identified from the f vector (step 30), and if possible, the first determination unit 130 determines the motion of the player only from the f vector (step 40). If there is, the second determination unit 160 determines the movement of the player by determining the transition of the pressure value for several types of movements estimated from the f vector (step 50).

The input board 30 of the motion determining apparatus according to this embodiment has three pressure sensors 34a, 34b, and 3b.
4c is arranged at a position corresponding to each vertex of the equilateral triangle,
Supporting step 32, the player inputs 3
The position of the foot is formed so as to enter the equilateral triangle when the player rides on 0 and plays. However, the size of the triangle is not limited to this, and may be determined depending on the position and position of the game depending on the game or simulator in which the motion determination device is used and the content of the motion to be measured.

Furthermore, the number of pressure sensors is not limited to three. A minimum of three can be used to check the inclination of the whole body, but more may be provided for more detailed checking. In particular, the transition of the load value at each point can be examined in detail as the number of measurement points increases,
It is preferable to provide many pressure sensors. At this time, the transition of the load value may be measured at all points, and the slope may be calculated by selecting some appropriate points among them. Further, the setting of the appropriate points may be changed depending on the situation.

Further, in the present embodiment, the transition of the pressure value is stored in the second determination condition storage section 150 as the determination condition,
Although it was judged whether or not it fits,
Various waveform patterns specific to the player's movement, such as 9 and 10 (A) to (D), may be stored in the memory in advance and the determination may be made by collating with the detected waveform.

FIG. 12 shows a functional block diagram of such a configuration. Compared with the block diagram of FIG. 1, the configuration is such that a waveform memory 170 is set instead of the second determination condition storage unit 150. Second determination unit 1
At 60, the transition of the pressure value stored in the pressure transition storage unit 140 is read out based on the determination result of the first determination unit 130, and the transition of the pressure value is compared with the waveform pattern stored in the waveform memory 170, thereby the movement of the player Judging.

Further, in the present embodiment, the change in the pressure value due to the player's motion is obtained as the inclination of the virtual board. However, the center of gravity is calculated from the detected value of the pressure sensor, and the player's motion is judged by the center of gravity. Good.

2. Second Embodiment Next, a preferred embodiment of a game device using the motion determination device of the present invention will be described in detail with reference to the drawings.

FIG. 13 shows a preferred example of a commercial fighting game device to which the present invention is applied.

This three-dimensional game device includes a display 40 displaying a game screen (visual field image) and speakers 50a and 50b outputting game sound. The operation unit for the player to operate the game includes a manual operation unit 20 including buttons and levers, and an input board 30 for the player to perform a stepping motion with his / her foot for input.

In the game device of this embodiment, the player can play against the enemy game character operated by the computer, and as a multi-player game, 2
Human players can also fight each other's game characters. In the latter case, two game machines are connected and each player plays a game while watching the same game space on each display.

When the game is started, the player plays the game shown in FIG.
Selecting a game character of one's own from the game characters 514, 516 shown in (A), and watching the game character's own 510 while seeing the game screen as shown in FIG. 14 (B).
Is instructed to compete with the enemy game character 512.

In such a game device, how to move the game character and reproduce it on the game screen is an important point that determines the fun of the game.

Conventionally, such a game device is not provided with an input board 30 for inputting by a player's stepping motion with his / her foot only by the manual operation section 20 consisting of only levers and buttons. Therefore, the player inputs the motion of the game character using only the manual operation unit 20 shown in FIG. Specifically, by operating the lever 28 and any button in combination, the game character is moved back and forth, left and right, jumped, or crouched.

However, the lever 28 serves as a direction indicating means.
When using a plurality of buttons, the number of directions that can be specified is limited. For example, when the XY axes are set on the game screen and the Z axis is set in the depth direction, if the movement on the XZ plane is performed by one lever 28, the game character is made to jump by using this lever 28. You cannot crouch. However, conventionally, such an input (jump, squat) is performed by combining the operation of the button and the lever 28, so the operation becomes complicated, and the movement and operation of the game character are separated and difficult to understand. there were.

Furthermore, the movement of the game character is limited only by the operation of the button and the lever 28, and thus the movement to be avoided on the spot, the change in the posture, etc. cannot be operated and input.

Moreover, the simulated experience that the player actually moves while fighting with the enemy fighter while moving like the game character was not possible.

However, in the game device of this embodiment,
The player can perform input in the Y-axis direction by jumping or squatting on the input board 30, and the player can also input motions to avoid, changes in posture, and the like by performing the motions. Therefore, the movement on the XZ plane is performed by operating the lever, and the movement on the XY plane is performed by the player's action (jump, squat).

That is, when the player inputs the posture of the game character (movement to avoid forward / backward / leftward / rightward or leans) or jumps or crouches (movement in the vertical direction), the player performs the action on the input board 30. Enter by doing.

By pressing the punch button 22, the own game character can make a punch attack on the opponent character. Further, by pushing the kick button 24, a kick attack can be applied to the opponent character. Also, by pressing the throw button 26,
It is possible to throw away the opponent character. However,
The throw button 26 functions as a throw button only when the distance between the game characters is smaller than a predetermined value.

As described above, the player inputs the action of the game character from the manual operation section 20 and the input board 30 and enjoys the battle-type game (martial arts game).

FIG. 15 is a functional block diagram of the commercial combat game apparatus of the embodiment.

The commercial martial arts game apparatus of the embodiment has a player operation section 10, an exercise determination section 100, and a game calculation section 2.
00 and a display 40.

The player operation section 10 includes a lever 28,
Punch button 22, kick button 24, throw button 26
And the like, and an input board 30 for inputting when the player rides on his / her feet. Input signals from the manual operation unit 20 such as the lever 28, the buttons 22, 24 and 26 are input to the game space setting unit 110 of the game calculation unit 100.

As shown in FIG. 2, the input board 30 includes a step 32, which is a mounting table on which the player rides, and three pressure sensors 34a for detecting the pressure applied to the step 32.
It is configured to include 34b and 34c, and is configured to also function as pressure detecting means. Player takes step 3
When standing on the second foot mark 31 and performing a movement such as avoiding or leaning back and forth, left and right, or a movement such as a jump, the pressure sensors 34a, 34b, 34c detect the pressure associated with the movement.

The pressure detected by the input board 30 is first inputted to the motion judging section 100 to judge the motion,
The determination result of the exercise determination unit 100 is input to the game calculation unit 200.

The exercise determination section 100 functions as exercise determination means for determining the exercise performed by the player based on the pressure detected by the input board 30, and the first determination condition storage section 11 is provided.
0, the inclination calculation unit 120, the first determination unit 130, the pressure transition storage unit 140, the second determination condition storage unit 150, and the second determination line unit 160. The functions of the respective units are the same as those in the first embodiment, so a detailed description is omitted.

The game calculation section 200 operates based on a predetermined program, the operation signal from the manual operation section 20 and the determination result of the motion determination section 100. The game space setting section 210 and the display object information. Storage unit 2
12. The image synthesizing unit 220 is included.

The game space setting section 210 is a manual operation section 2.
An operation signal from 0, that is, information indicating what kind of operation instruction the player has given from the lever 28, the buttons 22 to 26, and the determination result of the exercise determination unit 100 is received, and this information is temporarily stored and stored ( Hereinafter, these pieces of information will be referred to as operation instruction information). Furthermore, the game space setting unit 210 stores information about the current state of the game character, the game settings, and the like.
That is, the basic posture state, the state of being attacked by the opponent,
The state information such as the state of attacking the opponent, the jumping, the avoiding operation, and the throwing operation is stored. Furthermore,
The distance to the opponent game character is also stored as state information.

The game space setting section 210 determines what kind of motion the game character will perform based on the motion instruction information and the state information. That is, first, the manual operation unit 2
0 and whether or not the input from the motion determination unit 100 can be accepted is determined based on the state information. When the input is accepted, the manual operation unit 20 and the motion determination unit 10
How to move the game character is determined based on the input from 0, the distance between the game characters, and the like. For example, if the throw button 26 is pressed and the distance between the game characters is within a predetermined value, it is determined that the game character makes a motion of stroking the opponent. If the distance between the game characters is a predetermined value or more, the input of the throw button 26 is invalid.

When the game space setting unit 210 determines the motion of the game character, the motion pattern generation unit 214 in the game space setting unit 210 generates the determined motion pattern. For example, when the squatting motion is determined, the appearance of the game character (entire body, hand, shoulder,
16) from the state of FIG. 16 (A)
An operation pattern that changes to the state of (B) is generated. When the jump is further determined, the appearance of the game character (entire body, hand, shoulder, elbow, wrist, foot, etc.) changes from the state of FIG. 16 (B) to the state of FIG. 16 (C). Such an operation pattern is generated.

The display object information storage section 212 stores coordinate information about the head, body, limbs and swords of the game character, which is a display object, rotation information, and an object number which is information for designating an object representing the display object. (Hereinafter, such information is referred to as display object information) is stored. In this embodiment, an object representing a display object such as the head, body, limbs and sword of a game character is represented by combining a plurality of polygons.

The game space setting section 210 updates the display object information stored in the display object information storage section 212 every one field (1/60 seconds) based on the operation pattern generated by the operation pattern generating section 214. . Then, the updated display object information is output to the image combining unit 220.

In the game space setting section 210, calculations such as hit check between the punch and the enemy game character are performed, and when a hit occurs, a calculation process corresponding to the hit (the physical strength point of the hit game character is Lowering etc.) is also performed.

Further, the image synthesizing unit 220 inputs from the three-dimensional operation unit 230 that supplies the image information represented by the polygon, the object image information storage unit 260 that stores the image information of each object, and the three-dimensional operation unit 230. The image drawing unit 240 for obtaining the image information in the polygon based on the information of the polygon to be formed is included.

The object image information storage unit 260 in the image composition unit 220 stores the image information of the object designated by the object number in the display object information input from the game space setting unit 210.

The three-dimensional operation unit 230 reads out this object image information based on this object number. Here, the object is provided corresponding to the head, body, limbs, sword, etc. of the game character, and this object is a set of a plurality of polygons. The three-dimensional calculation unit 230 decomposes the object into a plurality of polygons, vertex coordinate information of these polygons, vertex texture coordinate information, etc. (hereinafter, these information are referred to as polygon information).
Etc. are subjected to perspective transformation into a viewpoint coordinate system, clipping processing, sorting processing, and the like. Then, the processed polygon information is sent to the image drawing unit 240.

The image drawing section 240 performs a calculation for obtaining image information such as color and brightness inside the polygon based on vertex coordinate information, texture coordinate information and the like included in the polygon information. As a result, the information of all the images forming the visual field image (game screen) is obtained, and the obtained image is displayed on the display 40, whereby the visual field image is formed.

As described above, in the game device in which the player inputs the motion of the game character on the screen, the motion of the character on the screen can be input by the player's own motion, not by operating the buttons, levers or the like. Like Therefore, it is possible to input a wider range of motions as compared with the case of inputting only buttons and levers, and since the movement of the player corresponds to the movement of the game character, the player can operate the game without feeling uncomfortable, and can be integrated with the game character. You can enjoy the game with your entire body.

The present invention is not limited to the above-mentioned embodiment, but various modifications can be made within the scope of the present invention.

For example, in the above embodiment, the input board 30 is used as a part of the input device, but a game device in which only the input board 30 is used as a game input may be used. Further, although the input board 30 is used for inputting the motion of the game character in the above-described embodiment, it may be a game in which the game character does not appear and the player himself / herself enjoys a simulated experience of various exercises and motions.

Further, for example, in the above-mentioned embodiment, the fighting game device was described as an example, but a game involving leaning or shifting of body weight such as skis, skateboards, virtual vehicles (flying boards), or avoiding exercise. It can also be used for games involving and other Zazen games (checking movement).

For example, it may be a game of operating a flying board that freely fly in outer space. If the input board of the present invention is used as an input device, the virtual board as described above can be regarded as a flying board, and the moving direction can be determined by the direction and size to which the force is applied. In the case of such a game device, a meteor, a floating object, or a spaceship appears on the screen, and the player rides on the input board 30 and moves the center of gravity to fly the flying board while avoiding obstacles. Enjoy playing games.

Further, it can be used as an input device of a simulation device not limited to a game. For example, it can be used in various fields as a device that reproduces human motion on an input board and displays an image. Also, since it is possible to measure the movement of a person on the input board, by evaluating the results, it can be applied as a training device for various sports, and can also be applied to medical equipment for motor function evaluation and training. .

According to the present invention, since it is possible to determine the movement state of the player such as walking, jumping, squatting, or the posture, the action of the player can be used as it is as an input of a simulation device for various sports or the like. . Therefore, it becomes possible for the player to provide a simulation device that allows the player to enjoy a simulated experience of actually playing a game. Furthermore, since it is possible to reproduce the movement of the player on the screen, the player can enjoy a realistic simulation experience while seeing his / her movement reflected in the image.
