[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a motion determination device, a motion determination method, a game device using the same, and a simulation device that perform motion input when a player performs a riding motion with a foot.
[0002]
[Background Art and Problems to be Solved by the Invention]
Recently, there has been proposed a three-dimensional ski game device in which a player rides on a board simulating a ski, performs virtual skiing in a virtual three-dimensional space, and displays the state on a display (Japanese Patent Laid-Open No. 3-212263). . However, the information that can be input from the board in such a game device 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 a player actually inputs the movement state, posture, etc. of the player such as walking, jumping, and squatting by actually performing the operation on the board.
[0003]
On the other hand, in a game apparatus that performs boxing or martial arts on a game screen, an input is performed by operating a button or a lever. In such a game device, the player must input the movement of the game character on the screen by operating buttons, levers, and the like.
[0004]
For this reason, a simulation experience in which a player actually fights an enemy fighter while moving in the space like a game character cannot be performed.
[0005]
In addition, since the movement of the game character is controlled only by operating the buttons and levers, the game operation becomes complicated, and the movement of the game character and the actual operation are liberated, which makes it difficult for beginners to understand the game operation. there were.
[0006]
Furthermore, the operation of the game character is limited only by the operation of the button and lever, and an input that expresses a complicated movement of an actual person cannot be performed.
[0007]
In a game device or the like, if it becomes possible to input a character's motion on the screen by the player's own operation instead of the operation of the button or lever, the complicated human operation is performed without performing a complicated game operation. Can be input. In addition, the player can get into the game operation without a sense of incongruity, and can enjoy the game with the whole body together with the game character.
[0008]
However, generally, a lot of information is necessary to determine the actual movement and motion state of a person, and the calculation for processing the information becomes complicated. For this reason, in the conventional game device, the player's own movement cannot be used for input.
[0009]
In addition, a simulation apparatus that can accurately detect an actual person's movement with a simpler configuration and simple arithmetic processing is desired for an apparatus that performs various exercise simulations, but there has been no such apparatus in the past. .
[0010]
The present invention has been made in view of such problems, and obtains information for determining the movement and motion state of a human body with a simple configuration, and processes the information with simple arithmetic processing. An apparatus, a motion determination method, and a game device and a simulation device using the motion determination device.

DETAILED DESCRIPTION OF THE INVENTION
Next, preferred embodiments of the present invention will be described in detail with reference to the drawings.
[0049]
1. First embodiment
FIG. 1 is a functional block diagram of an exercise determination device according to an embodiment of the present invention, and FIG. 2 is an explanatory diagram of an input board 30.
[0050]
The exercise determination device includes an input board 30 that functions as an exercise input unit and an exercise determination unit 100. Note that 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 which the determination result is input to the game device will be described later.
[0051]
As shown in FIG. 2, the input board 30 includes a step 32 on which a player rides, and three pressure sensors 34a, 34b, and 34c that detect the pressure applied to the step 32.
[0052]
In step 32, the reference position on which the player rides is displayed as a foot mark 31, and when the player stands on the foot mark 31 in step 32 and performs an exercise such as avoiding or tilting back and forth, left and right, or jumping, The three pressure sensors 34a, 34b, 34c arranged on the non-linear line respectively detect the pressure accompanying the movement.
[0053]
The pressure detected by the input board 30 is input to the motion determination unit 100 to determine motion.
[0054]
The exercise determination unit 100 functions as an exercise determination unit that determines the exercise performed by the player based on the pressure detected by the input board 30, and includes a first determination condition storage unit 110, an inclination calculation unit 120, a first determination unit 130, The pressure transition storage unit 140, the second determination condition storage unit 150, and the second determination unit 160 are configured.
[0055]
Next, a function and an action for determining the player's movement based on an input from the input board 30 will be described in detail separately for the input board 30 and the movement determination unit 100.
[0056]
First, the configuration and operation of the input board 30 will be described below.
[0057]
FIG. 2 is a diagram showing the pressure sensors 34a, 34b, and 34c arranged inside in order to detect the pressure applied to the step 32 and the step 32 of the input board 30 of the present embodiment.
[0058]
The three pressure sensors 34a, 34b, 34c are arranged at positions corresponding to the vertices of the equilateral triangle, support the step 32, and when the player plays on the footrest portion 31 of the input board 30, Is located so that it falls within the equilateral triangle.
[0059]
The three pressure sensors 34a, 34b, and 34c are set so that the detected pressure becomes zero when no one is on the input board 30. When the player gets on the input board 30, the three pressure sensors 34a, 34b, 34c detect the pressure based on the weight of the player. When the player is resting on the input board 30, the total pressure detected by the three pressure sensors 34a, 34b, 34c is equal to the weight of the player. When the player performs a movement such as jumping or squatting on the input board 30, tilting the state, or changing the posture, the pressure values detected by the three pressure sensors 34a, 34b, and 34c change variously. .
[0060]
The three pressure sensors 34a, 34b, and 34c used in the present embodiment include a capacitor composed of two conductive plates that are separated from each other by applying force, and this capacitor is incorporated in an astable multivibrator circuit. It has a configuration. 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 in this frequency. Specifically, a change in pressure from 0 kg to 70 kg is output as a clock signal of about 20 KHz to 14 KHz.
[0061]
FIG. 3A shows a specific block diagram of such an input board 30, and FIG. 3B shows a more specific circuit diagram of the interface. As shown in FIG. 3A, the input board 30 includes three pressure sensors 34a, 34b, and 34c, an interface 35 that converts a change in frequency output from each sensor into a clock signal, and a power source 36. ing.
[0062]
Further, as shown in FIG. 3B, the interface 35 includes a changeover switch 33 that switches the input from each sensor, a reference clock circuit 42 that outputs a reference clock, and the number of reference clocks per pulse that the sensor outputs. An 8-bit binary counter 37 for counting, a latch circuit 38 for latching the output of the 8-bit binary counter 37, and a controller 39 for controlling the operations of the 8-bit binary counter 37 and the latch circuit 38 are included.
[0063]
Then, by connecting the interface 35 to the I / O port 92 of the movement determination unit 100, the movement determination unit 100 can obtain information on the pressure detected by each sensor 34a, 34b, 34c.
[0064]
Next, detailed functions and actions of each part of the motion determination unit 100 and the principle of motion determination will be described in detail.
[0065]
When the player rides on the input board 30 and moves, the pressure sensors 34a, 34b, and 34c provided at the three support points detect the pressure. For example, when the player tilts 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 player's stepping force immediately before the start of the jump, and no pressure is applied to the board during the jump, so the pressure value at each point becomes zero. As described above, the pressure value at each point varies depending on the movement of the player.
[0066]
The inventor of the present application has a close relationship between the detected pressure and the player's motion, and if the motion to be determined is limited, the player's motion can be identified as the motion to be determined based on the pressure. I found. Thus, by measuring the pressure value at each point and its change in the motion to be determined, a certain pattern was found in the player's motion and the pressure value at each point and the data change. Therefore, in the exercise determination device according to the present embodiment, the first determination condition storage unit 110 of the exercise determination unit 100, the second determination, and the determination target exercise determined from the pattern with respect to the limited determination target exercise. The condition storage unit 150 is stored in advance, and the player's exercise is determined based on the determination condition.
[0067]
Specifically, in order to specify the player's forward / backward / left / right movement, the necessary determination conditions are necessary to specify more detailed exercises such as squatting and jumping in the first determination condition storage unit 110. Various determination conditions are stored in the second determination condition storage unit 150.
[0068]
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.
[0069]
That is, when the former determination is performed, the inclination calculation unit 120 performs an operation for obtaining the inclination of the virtual board based on the pressure value detected by the input board 30, and the first determination unit 130 stores the first determination condition storage unit 110 in the first determination condition storage unit 110. The player's motion is determined based on the stored determination condition and the inclination of the virtual board.
[0070]
When the latter determination is made, the pressure transition storage unit 140 stores the transition of the pressure value due to the player's exercise. Next, the second determination unit 160 determines the player's exercise based on the determination result of the first determination unit 130 and the determination condition stored in the second determination condition storage unit 150 and the transition of the pressure value.
[0071]
The relationship between the transition of the virtual board inclination and pressure value and the player's movement will be described in detail later. First, the function of the inclination calculating unit 120 calculating the inclination of the virtual board will be described in detail.
[0072]
The inclination calculation unit 120 uses a virtual plane (hereinafter referred to as a virtual board) in which x and y, which are plane coordinates of three support points, are x and y coordinates, and a pressure applied to the three support points is a z coordinate. It is assumed that a parameter representing an inclination with respect to a horizontal plane (xy plane) is calculated.
[0073]
A method for calculating a parameter representing the inclination of the virtual board performed by the inclination calculation unit 120 will be described with reference to FIGS.
[0074]
4A and 4B, the plane coordinates of the three support points, which are the horizontal positions of the sensors 34a, 34b, and 34c, are x-coordinates and y-coordinates, and the detected pressure values of the sensors at the three support points are z-coordinates. It is expressed in an xy plan view. When the pressure is 0, the sensors 34a, 34b, and 34c are on the xy plane, and the center of gravity at this time is the origin.
[0075]
A, B, and C shown in FIG. 4A represent the positions of the pressure sensors 34a, 34b, and 34c when no pressure is applied. In this case, each point is located on the xy plane. .
[0076]
FIG. 4B shows the case where pressure is applied to each point. ^' , B ^' , C ^' Represents the virtual positions of the pressure sensors 34a, 34b, 34c, respectively. In this case A ^' , B ^' , C ^' X which is the X coordinate of ^' 1, x ^' 2, x ^' 3, y which is the Y coordinate ^' 1, y ^' 2, y ^' 3 is equal to x1, x2, x3, which are the X coordinates of A, B, and C in FIG. 4A, and y1, y2, y3, which are the Y coordinates. A ^' , B ^' , C ^' Z which is the Z coordinate of ^' 1, z ^' 2, z ^' 3 is a pressure value output from each sensor.
[0077]
FIG. 5A shows the ABC and A. ^' B ^' C ^' Is represented in a three-dimensional space of xyz.
[0078]
Here, a plane including three points ABC is defined as α, three points A ^' B ^' C ^' The plane containing ^' Then this plane α ^' Is a virtual plane including a virtual board. This virtual plane α ^' Takes various inclinations according to the pressure value output from each sensor. Since this inclination is closely related to the movement of the player as will be described later, the movement of the player can be determined based on this inclination.
[0079]
In the inclination calculation unit 120 of the present embodiment, C in order to quantify this inclination. ^' A ^' Vector and C ^' B ^' C, the outer product vector of vectors ^' Seeking a vector. C ^' A ^' Vector = (Ax, Ay, Az), C ^' B ^' If vector = (Bx, By, Bz), C is an outer product vector. ^' Vector = (Cx, Cy, Cz) is
Cx = Ay x Bz-Az x By
Cy = Az x Bx-Ax x Bz
Cz = Ax x By-Ay x Bx
Is required.
[0080]
This C ^' The vector is 3 points A ^' B ^' C ^' Therefore, the direction is the same as the normal vector μ of the virtual plane shown in FIG. This C ^' When the vector is projected on the xy plane with the origin as the starting point, as shown in FIG. ^' The end point of the vector is projected to point E (Cx, Cy, 0). In this embodiment, the OE vector is used as a parameter representing the inclination of the virtual board, with the y-axis direction being front and rear and the x-axis direction being left and right.
[0081]
Next, the pressure transition storage unit 140 and the second determination unit 160 will be described.
[0082]
The pressure transition storage unit 140 is configured to store the pressure value at each point input from the input board 30 and the pressure value applied to the virtual board from the pressure value at each point for a given time. As described above, the second determination condition storage unit 150 stores a condition for determining the player's movement from the transition of the pressure value. The movement of the player is determined from the transition of the pressure value stored in the storage unit 140.
[0083]
A method of calculating the pressure value applied perpendicular to the virtual board will be described with reference to FIG.
[0084]
In the pressure transition storage unit 140 of the present embodiment, the pressure value applied to the virtual board is obtained by calculating the area as follows in order to reduce the calculation load of the CPU.
[0085]
A in FIG. ^' , B ^' , C ^' Represents the virtual positions of the pressure sensors 34a, 34b, and 34c, respectively, as in FIG. A ^'' , B ^'' , C ^'' Respectively represent the output values of the pressure sensors 34a, 34b and 34c at the point A. ^' , B ^' , C ^' This is a point obtained by adding to the X and Y coordinates.
[0086]
That is, A ^' (X _' 1, y _' 1, z _' 1), B ^' (X _' 2, y _' 2, z _' 2), C ^' (X _' 3, y _' 3, C _' 3), A ^'' (X _'' 1, y _'' 1, z _'' 1), B ^'' (X _'' 2, y _'' 2, z _'' 2), C ^'' (X _'' 3, y _'' 3, C _'' 3) _' 1, z _' 2, z _' 3 is the output value of each of the pressure sensors 34a, 34b, and 34c. Therefore, each value is obtained by the following equation.
[0087]
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
Based on the values thus obtained, the triangle A ^'' B ^'' C ^'' Is used as a pressure value applied to the virtual board.
[0088]
The pressure values detected by the pressure sensors 34a, 34b, and 34c are naturally different if the player's weight is different even if the player's exercise is the same. The pressure applied to the board by the player's exercise is proportional to the player's weight. For this reason, in this embodiment, the determination condition is set as a 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, and 34c based on the player's weight. It is corrected as follows. Note that the weight of the player is determined by the detected pressure value in the stationary state of the player.
[0089]
Assuming that the model weight value is W1, the player's weight value is W2, and the detected values of the pressure sensors are Sa, Sb, and Sc, their correction values are Sa. ^' , Sb ^' , Sc ^' Is
Sa ^' = Sa x W1 ÷ W2
Sb ^' = Sb x W1 ÷ W2
Sc ^' = Sc x W1 ÷ W2
Is required.
[0090]
As described above, in this embodiment, after correcting the detection values of the pressure sensors 34a, 34b, and 34c as described above, the parameter representing the inclination of the virtual plane and the pressure value perpendicular to the virtual plane are calculated, and the player Therefore, the player's exercise can be determined according to preset determination conditions regardless of the player's weight.
[0091]
By the way, what is important in recognizing a motion in this way is that the obtained information and the predicted motion are not linked one-on-one. That is, there are a plurality of exercises that are expected from the obtained information, and how to determine which one corresponds is a problem. The exercise determination unit 100 of 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 point is also an important point of the present invention.
[0092]
For example, when supposing surfing and boxing exercises, the sensor output is similar to the exercise of turning to the right by the surfboard and the exercise of avoiding the punch to the right. Therefore, the player's exercise can be accurately determined by specifying the exercise to be determined in advance as one of various exercises in surfing or various exercises in boxing. Thus, 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. .
[0093]
Accordingly, 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.
[0094]
The examples given in FIGS. 7, 8, and 9 are obtained by examining pattern results by graphing experimental results obtained by measuring the inclination of the virtual board and the transition of the pressure value, assuming martial arts such as boxing.
[0095]
7A, 7B, and 7C are graphs showing temporal transitions of correction values Sa, Sb, and Sc of pressure values detected by the pressure sensors 34a, 34b, and 34c. FIG. 7D is a graph showing temporal transition of the pressure value Sd applied to the virtual board in the vertical direction.
[0096]
In these graphs, the horizontal axis represents time and the vertical axis represents the output value of each sensor when the player is resting on the input board 30 as the reference position 0 (in the motion determination device of this embodiment, each The sensor output waveform is corrected based on the weight of the player). Therefore, for example, when the player moves to the right from a stationary state, the output waveform of FIG. 7A touches the + direction, and the output waveform of FIG. 7B touches the-direction.
[0097]
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 the time t. ₁ Is a parameter that represents the inclination of the virtual board. That is, the f vector is a vector obtained by projecting the aforementioned outer product vector onto the xy plane.
[0098]
The relationship between the inclination of the virtual board shown in the xy plan view of FIG. 7E and the player's movement will be clarified with reference to FIG.
[0099]
FIG. 8 is an xy plan view showing the relationship between the inclination of the virtual board and the player's movement, as in FIG. Each vector of fa, fb, fc, fd, and fe in this graph is a parameter that represents the inclination of the virtual board during various movements of the player, like the f vector of FIG.
[0100]
In addition, when the respective regions a, b, c, d, and e separated by the chain line in this graph are represented by (a), (b), (c), (d), and (e), the respective regions are represented by the player. It represents the range specific to each movement. In other words, the player's movement can be specified depending on which of the above-mentioned areas the end point of each vector of fa to fe that is a parameter representing the inclination of the virtual board belongs.
[0101]
When the end point of the vector generated by the player's motion is within the range of (a) as in the fa vector, the change in the inclination of the virtual board is small, so the player is either a small body motion (footwork) or the input board It is moving perpendicular to 30 (squatting, jumping). Whether it is (footwork) (squatting) or (jump) at this time is determined based on the transition of the pressure value at each point described later.
[0102]
If the end point of the vector generated by the player's motion is within the range of (b) or (c), such as the fb vector or the fc vector, a large change has occurred in the horizontal direction, so the player can punch, etc. Doing exercises to avoid from side to side or walking. In this case as well, which movement is determined based on the transition of the pressure value at each point described later.
[0103]
When the end point of the vector generated by the player's movement is within the range of (e) as in the fe vector, the virtual plane is greatly inclined backward, so the player moves backward to avoid punches and the like. ing. At this time, the magnitude of the inclination represents the magnitude of the movement.
[0104]
When the end point of the vector generated by the player's motion is within the range of (d) as in the fd vector, the virtual plane is greatly tilted forward, so that the player moves forward to avoid punching (for example, , Exercise to lower your head). At this time, the magnitude of the inclination represents the magnitude of the movement.
[0105]
Thus, the player's movement is roughly specified by the inclination of the virtual board. In particular, the forward / backward / left / right inclination (motion to avoid) is almost specified.
[0106]
So, how do you distinguish between exercises other than avoiding exercises such as squatting, jumping, and footwork, and avoiding left and right exercises and walking exercises? In such a case, the motion determination apparatus according to the present embodiment makes the determination by combining the inclination of the virtual board and the transition of the pressure value at each point.
[0107]
How to determine in such a case will be described with reference to FIGS. FIG. 9 is a graph when squatting. When the player crouches from an upright state, the pressure is within a certain range and the pressure is above a certain level within a certain range of the virtual board. Therefore, the range of the inclination of the virtual board is determined by the range to which the end point of the f vector in FIG. 9E belongs, and the pressure state is the pressure value at each point shown in the graphs of FIGS. Judgment based on the transition.
[0108]
First, since the end point of the f vector in FIG. 9E is within the range of (a) shown in FIG. 8, the player can perform a small upper body movement (footwork) or a movement perpendicular to the input board 30 ( It is judged that he is squatting or jumping. At this time, whether it is (footwork) or (squatting) or (jump) is determined based on the transition of the pressure value at each point shown in the graphs (A) to (D). At t2 in FIGS. 9A to 9D, a pressure value equal to or greater than a certain value is detected, and at this time, it is determined that the vehicle is in a squatting state.
[0109]
Generally, when a player avoids in a certain direction, a force for stepping in is applied in a direction 180 ° opposite to the direction avoided before. This force is a force that increases if the movement is agile. Similarly, in the case of squatting, there is a state in which the pressure decreases before the inclination decreases.
[0110]
In this way, there is always a force to step in before the intentional movement (the direction opposite to the direction of movement). By recognizing this force, it can be distinguished from intentional movement and unconscious movement or body shake.
[0111]
The jump is a state where no pressure is applied to the input board 30. The subsequent landing is a state where 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.
[0112]
FIG. 10 is a graph in the case of walking exercise. 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 a motion to avoid left or right or a walking motion. At this time, it is determined based on the transition of the pressure value at each point shown in the graphs (A) to (D) whether the motion is to be avoided to the left or right or the walking motion.
[0113]
When the player performs a walking exercise, a specific waveform diagram in which the pressure alternately moves to the right (A) and the left (B) within the range of the weight of the player as shown in FIG. When the legs are lifted, the width of the pressure movement is within a certain range depending on the weight of the rider, so that it can be distinguished from the shaking of the body. Therefore, if the detected waveform shows such a pattern, it is determined as a walking motion.
[0114]
As described above, the motion determination unit 100 according to the present embodiment identifies the motion to be determined in advance, and then determines the player's motion by combining the inclination of the virtual board and the transition of the pressure value at each point. ing.
[0115]
FIG. 11 is a flowchart illustrating a procedure when the motion determination unit 100 performs the determination.
[0116]
First, the inclination calculation unit 120 calculates the f vector, which is a parameter representing the inclination of the virtual board (step 10). Next, the first determination unit 130 determines which region (a) to (e) in FIG. 8 belongs to the f vector (step 20).
[0117]
At this time, if the region to which the f vector belongs is (d) or (e), it can be specified that the exercise avoiding forward or backward is performed as described above. However, if the region 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 or not the motion can be specified from the f vector (step 30), and if possible, the first determination unit 130 determines the player's motion from only the f vector (step 40). If there is, the second determination unit 160 determines the player's motion by determining the transition of the pressure value for several types of motion estimated from the f vector (step 50).
[0118]
In the input board 30 of the motion determination device of the present embodiment, the three pressure sensors 34a, 34b, 34c are arranged at positions corresponding to the vertices of the equilateral triangle and support the step 32, and the player inputs When playing on the board 30, the foot is positioned so that it falls within the equilateral triangle. However, the size of the triangle is not limited to this, and is determined by the position and position of the game or simulator in which the motion determination device is used, and the content of the motion to be measured.
[0119]
Further, the number of pressure sensors is not limited to three. In order to examine the inclination of the whole body, it is possible to use at least three, but more may be provided for more detailed examination. In particular, it is preferable to provide a large number of pressure sensors since the movement of the player can be examined more finely as the number of measurement points increases in the transition of the load value at each point. 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. Further, it may be formed so that the setting of the appropriate point can be changed according to the situation.
[0120]
Further, in this embodiment, the transition of the pressure value is stored in the second determination condition storage unit 150 as a determination condition, and the determination is made based on whether or not the change is satisfied. Various waveform patterns peculiar to the player's movement such as (D) to (D) may be stored in the memory in advance, and the determination may be made by collating with the detected waveform.
[0121]
FIG. 12 shows a functional block diagram in such a configuration. Compared to the block diagram of FIG. 1, the waveform memory 170 is set instead of the second determination condition storage unit 150. Based on the determination result of the first determination unit 130, the second determination unit 160 reads the pressure value transition stored in the pressure transition storage unit 140 and collates it with the waveform pattern stored in the waveform memory 170. The player's exercise is judged.
[0122]
In this embodiment, the change in the pressure value due to the player's movement is obtained as the inclination of the virtual board. However, the center of gravity may be calculated from the detected value of the pressure sensor, and the movement of the player may be determined based on the center of gravity.
[0123]
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.
[0124]
FIG. 13 shows a preferred example of a commercial martial arts game device to which the present invention is applied.
[0125]
This three-dimensional game apparatus includes a display 40 on which a game screen (view field image) is projected, and speakers 50a and 50b from which game sounds are output. The operation unit for the player to operate the game includes a manual operation unit 20 configured with buttons, levers, and the like, and an input board 30 for the player to ride and input with his / her feet.
[0126]
In the game device of this embodiment, the player can play against an enemy game character operated by a computer, or two players can fight each other's game characters as a multiplayer game. In the latter case, two game machines are connected, and each player plays a game while viewing the same game space on each display.
[0127]
When the game is started, the player selects his / her game character from the game characters 514 and 516 shown in FIG. 14A and looks at the game screen as shown in FIG. An action is instructed and a battle with the enemy game character 512 is performed.
[0128]
In such a game apparatus, how to move the game character and reproduce it on the game screen is an important point that determines the fun of the game.
[0129]
Conventionally, such a game apparatus has not been provided with the input board 30 for inputting by the player performing a riding motion with his / her foot only by the manual operation unit 20 including only a lever and a button. Therefore, the player inputs the action of the game character only with the manual operation unit 20 shown in FIG. Specifically, the game character is moved back and forth, left and right, jumped, or squatted by operating the lever 28 and any button in combination.
[0130]
However, when the lever 28, a plurality of buttons, etc. are used as the direction indicating means, the number of directions that can be indicated is limited. For example, when the XY axis is 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 caused to jump using the lever 28. It cannot be crouched or crouched. Conventionally, however, such an input (jump, squat) has been performed by combining the operation of the button and the lever 28, so that the operation becomes complicated, and the movement and operation of the game character are liberated and difficult to understand. there were.
[0131]
Furthermore, the movement of the game character is limited only by the operation of the button and the lever 28, and it is not possible to input an operation to avoid on the spot, a change in posture, and the like.
[0132]
In addition, a simulation experience in which the player actually fights the enemy fighter while moving like a game character was not possible.
[0133]
However, in the game device according to the present embodiment, the player himself / herself jumps or crouches on the input board 30 to input in the Y-axis direction, and the player performs the motions to be avoided and changes in posture, etc. You can input by doing. Therefore, the movement on the XZ plane is performed by lever operation, and the movement on the XY plane is performed by the player's operation (jumping, squatting).
[0134]
That is, inputs such as the posture of the game character (a motion that avoids or tilts forward / backward / left / right), jumping or squatting (a vertical motion) are performed by the player performing the motion on the input board 30. input.
[0135]
Also, by pressing the punch button 22, the player's own game character can make a punch attack against the opponent character. Further, by pressing 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 game characters is smaller than a predetermined value.
[0136]
As described above, the player inputs the action of the game character from the manual operation unit 20 and the input board 30, and enjoys a battle-type game (a martial art game).
[0137]
FIG. 15 shows a functional block diagram of the commercial martial arts game device of the embodiment.
[0138]
The commercial martial arts game device of the embodiment includes a player operation unit 10, an exercise determination unit 100, a game calculation unit 200, and a display 40.
[0139]
The player operation unit 10 includes a manual operation unit 20 such as a lever 28, a punch button 22, a kick button 24, and a throw button 26, and an input board 30 that inputs when the player rides with his / her foot. Input signals from the manual operation unit 20 such as the lever 28, buttons 22, 24, and 26 are input to the game space setting unit 110 of the game calculation unit 100.
[0140]
As shown in FIG. 2, the input board 30 includes a step 32 on which a player rides, and three pressure sensors 34a, 34b, 34c for detecting the pressure applied to the step 32, and pressure detecting means. Is also configured to function. When the player stands on the foot mark 31 in step 32 and performs a motion such as avoiding or tilting back and forth, left and right, or jumping, the pressure sensors 34a, 34b, and 34c detect pressures associated with the motion.
[0141]
The pressure detected by the input board 30 is first input to the motion determination unit 100 to determine the motion, and the determination result of the motion determination unit 100 is input to the game calculation unit 200.
[0142]
The exercise determination unit 100 functions as an exercise determination unit that determines the exercise performed by the player based on the pressure detected by the input board 30, and includes a first determination condition storage unit 110, an inclination calculation unit 120, a first determination unit 130, The pressure transition storage unit 140, the second determination condition storage unit 150, and the second determination strip unit 160 are configured. Since the function of each part is the same as that of the first embodiment, a specific description is omitted.
[0143]
The game calculation unit 200 operates based on a predetermined program, an operation signal from the manual operation unit 20 and a determination result of the movement determination unit 100, and includes a game space setting unit 210 and a display object information storage unit 212. The image composition unit 220 is included.
[0144]
The game space setting unit 210 receives an operation signal from the manual operation unit 20, that is, information on what operation instruction the player has given based on the determination result of the lever 28, the buttons 22 to 26, and the movement determination unit 100. Information is temporarily stored and stored (hereinafter, this information is referred to as operation instruction information). Further, the game space setting unit 210 stores information on what state the game character, the game setting, etc. are currently in. That is, state information such as a basic posture state, a state of being attacked by the opponent, a state of attacking the opponent, jumping, avoiding operation, throwing operation, and the like are stored. Further, the distance from the opponent game character is also stored as state information.
[0145]
The game space setting unit 210 determines what action the game character performs based on the action instruction information and the state information. That is, first, it is determined based on the state information whether or not inputs from the manual operation unit 20 and the exercise determination unit 100 can be accepted. Then, when an input is received, it is determined how to operate the game character based on the input from the manual operation unit 20 and the motion determination unit 100, 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 moves the opponent. If the distance between game characters is equal to or greater than a predetermined value, the input of the throw button 26 is invalid.
[0146]
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 action is determined, the game character's appearance (the entire body, hands, shoulders, elbows, wrists, feet, etc.) changes from the state shown in FIG. 16A to the state shown in FIG. Such an operation pattern is generated. If jump is further determined, the game character's appearance (the entire body, hands, shoulders, elbows, wrists, feet, etc.) changes from the state shown in FIG. 16B to the state shown in FIG. Such an operation pattern is generated.
[0147]
The display object information storage unit 212 includes coordinate information, rotation information, and object numbers (hereinafter, referred to as objects indicating the display object) of the game character's head, torso, limbs, and sword, which are display objects. Such information is called display object information). In the present embodiment, objects representing display objects such as the head, torso, limbs, and sword of the game character are expressed by combining a plurality of polygons.
[0148]
The game space setting unit 210 updates the display object information stored in the display object information storage unit 212 for each field (1/60 seconds) based on the operation pattern generated from the operation pattern generation unit 214. Then, the updated display object information is output to the image composition unit 220.
[0149]
In the game space setting unit 210, for example, a calculation such as a hit check between a punch and an enemy game character is also performed. If a hit occurs, a calculation process corresponding to the hit (such as lowering a hit point of the hit game character) Is also done.
[0150]
The image composition unit 220 also includes a three-dimensional calculation unit 230 that supplies image information represented by polygons, an object image information storage unit 260 that stores image information of each object, and a polygon input from the three-dimensional calculation unit 230. The image drawing unit 240 that obtains image information in the polygon based on the information is included.
[0151]
The object image information storage unit 260 in the image composition unit 220 stores the image information of the object specified by the object number in the display object information input from the game space setting unit 210.
[0152]
The three-dimensional calculation unit 230 reads out the object image information based on the object number. Here, the object is provided corresponding to the head, torso, limbs, sword, and the like 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, and sees them into the viewpoint coordinate system with respect to vertex coordinate information, vertex texture coordinate information, and the like (hereinafter referred to as polygon information) of these polygons. Perform conversion, clipping, sorting, etc. The processed polygon information is sent to the image drawing unit 240.
[0153]
The image drawing unit 240 performs an operation for obtaining image information such as color and brightness inside the polygon based on the vertex coordinate information, texture coordinate information, and the like included in the polygon information. As a result, information on all images constituting the view field image (game screen) is obtained, and the obtained image is displayed on the display 40, thereby forming a view field image.
[0154]
In this way, in a game device in which the player inputs the action of the game character on the screen, the action of the character on the screen can be input by the player's own action instead of the operation of the button or lever. . Therefore, it is possible to input a wide range of motions compared to input using only buttons and levers, and the movement of the player corresponds to the movement of the game character, so that the player can operate the game without a sense of incongruity and unite with the game character. And enjoy the game with your whole body.
[0155]
In addition, this invention is not limited to the said Example, Various deformation | transformation implementation is possible in the range of the summary of this invention.
[0156]
For example, in the above-described embodiment, the input board 30 is used as a part of the input device. However, a game device that uses only the input board 30 as a game input may be used. In the above-described embodiment, the input board 30 is used to input the motion of the game character. However, the game may be a game in which the game character does not appear and the player himself can enjoy various exercises and motion simulation experiences.
[0157]
Further, for example, the martial arts game device has been described as an example in the above embodiment, but a game involving body tilt and weight movement, such as skiing, skateboarding, and a virtual vehicle (flying board), or a game involving avoidance exercise. It can also be used for other zazen games (checking movements).
[0158]
For example, it may be a game of maneuvering a flying board that flies freely in outer space. When the input board of the present invention is used as an input device, the virtual board as described above can be seen as a flying board, and the moving direction can be determined based on the direction and size of the force. In the case of such a game apparatus, meteorites, floating objects, and spaceships appear on the screen, and the player rides on the input board 30 and moves the center of gravity, thereby flying while maneuvering the flying board and avoiding obstacles. Enjoy playing games.
[0159]
Further, the present invention can be used as an input device for a simulation device that is not limited to a game. For example, it can be used in various fields as a device that reproduces the movement of a person on an input board and displays an image. In addition, since it is possible to measure the movement of a person on the input board, it can be applied to various sports practice devices by evaluating the results, and can also be applied to medical equipment for exercise function evaluation and training. .
[0160]
According to the present invention, it is possible to determine the player's walking state, jumping, squatting, and other movement states, postures, and the like, so that the player's movements can be used as they are as inputs for various sports simulation devices. Therefore, it is possible to provide a simulation apparatus that allows the player to enjoy a simulation experience as if he / she actually played a game. Furthermore, since the movement of the player can be reproduced on the screen, the player can enjoy a simulated experience full of realism while watching his / her movement reflected in the image.
