Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a walking-type sensation game device, and more particularly to, for example, a game device in which a game player walks or runs on a belt mechanism supported on a three-axis support base. The present invention relates to a novel walking-type sensation game device that changes a position.

[0002]

2. Description of the Related Art Conventionally, "road runner" and "Pac-Man" (both are trade names) are known as examples of walking video games. In these games, the main character (player object) is a game in which treasures such as gold nuggets are collected while avoiding enemies. The game player walks or runs on the screen by moving a player object as his / her avatar by pressing a specific key or button on the controller or the keyboard. Then, the player object collects treasures in a specific place while passing through various patterns of passages, and when all the treasures have been collected, moves to the next screen (stage). At this time, there is a villain character as an enemy of the hero, and the hero follows the hero along a passage by a given tracking algorithm. The game ends when the game player clears all stages or the villain character catches up with the hero.

[0003]

In a conventional video game, a hero (player object) on the screen moves along a passage in the screen at a preset speed while pressing a specific key or button. And the movement of the player object depends on a key or button operation.
Therefore, the correspondence between the movement motions of the game player and the player object is arbitrary, and the game proceeds only by the movement of the video destination, so that the game player has a small feeling of immersion in the game.

[0004] Therefore, a main object of the present invention is to provide a novel walking-type bodily sensation game device capable of improving a feeling of immersion in a game by associating a motion action between a game player and a player object.

[0005]

A walking-type sensation game device according to the present invention is a walking-type sensation game device for displaying a player object and other objects on a game screen. , A walking speed detecting means for detecting at least a walking speed of the game player on the walking feeling presenting mechanism, and an object moving means for moving the player object at a moving speed corresponding to the walking speed.

[0006]

In the present invention, the game player actually walks in the real space using the walking sensation presentation device. When the walking sensation presentation mechanism is a belt mechanism, the game player walks or runs on the belt mechanism, detects the position of both feet of the game player with, for example, an infrared camera, and determines the walking speed of the game player according to the two feet positions. To detect. The object moving means is, for example, a computer, and the object moving means moves the player object on the game screen at a moving speed proportional to the walking or running speed of the game player.

When a belt mechanism is used as the walking sensation presentation mechanism, for example, a push button switch operable by a game player is provided, and the support base inclines the belt mechanism in accordance with the operation of the push button switch.
According to the slope displayed on the game screen, it is possible to give the game player a load of going up and down a hill and taste the real feeling.

When the distance between the enemy object and the player object on the game screen becomes smaller than a predetermined value, the first contact determination means determines that the two have contacted each other.
When they come into contact, for example, the life of the player object may be reduced or the game may be ended.

When a target object such as a gold bullion is displayed on the game screen, the second contact determining means determines contact between the target object and the player object. When the two come into contact with each other, for example, a score may be counted.

[0010]

According to the present invention, the speed at which the game player actually walks or runs on the belt mechanism is reflected on the moving speed of the player object on the game screen. The game player's feeling of immersion in the game is improved as compared with the case where the movement of the player object is simply controlled with a fingertip.

The above and other objects, features, and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A walking-type sensation game device (hereinafter, may be simply referred to as a "game device") 10 according to an embodiment of the present invention shown in FIG.
2 inclusive. The belt mechanism 12 is a mechanism for canceling the movement due to walking when the pedestrian 14 walks thereon, and is installed on the triaxial walking surface support 16. Here, the pedestrian 14 is a game player who plays this walking-type experience game. Game device 10 of this embodiment
Is to transmit such movement or walking information of the game player 14 to the display 18 via a computer to move the player object on the game screen.

In this embodiment, a belt mechanism on which the game player actually walks is used as the walking sensation presentation mechanism. However, a pedal-type walking sensation presentation mechanism that has a pedal like a bicycle, for example, can detect the speed according to the speed at which the game player depresses the pedal, and can present a sensation of a slope by applying a load to the pedal. May be used.

Referring to the game screen shown in FIG. 2, a passage is fixedly displayed on the game screen, and the passage includes a horizontal passage HR extending horizontally at an appropriate interval in the height direction. And an inclined passage (slope) SL for connecting the horizontal passages HR spaced at an appropriate position at an appropriate position. The player object (main character) PO, which is an avatar of the game player 14, goes for a gold bar GI placed at an appropriate position in the horizontal passage HR while dodging the enemies EP and EA. The movement of the player object PO at this time is controlled depending on the walking or running of the game player 14 on the belt mechanism 12. Note that the enemy object EP moves by the same walking or running of another game player (not shown). However, in FIG. 1, illustration of a belt mechanism and the like for other game players is omitted. The movement of the enemy object EA is automatically controlled by a computer 32 described later. The moving direction of each of the objects PO, EP, and EA is basically from right to left on the game screen.

A game screen as shown in FIG. 2 is divided into blocks of an appropriate size as shown in FIG. 3, and each block has one of “1”, “0” and “−1”. Have been assigned. Such numbers are used for internal processing of the game screen. For example, the number "-
"1" means that the block is "empty" without a horizontal passage. When the block of the number "-1" comes, not only the player object OP but also the enemy object falls and is directly under the block. Move on a horizontal passage. In the block to which the number “1” is assigned, when the game player 14 presses a push button 28 described later when the slope SL exists in the traveling direction, the player object PO can move up and down the slope SL. In a block to which the number “0” is assigned, for example,
When the game player 14 presses the push button 28, an effect in the game such as making a hole in a horizontal passage ahead of the player object PO in the traveling direction can be considered.

The belt mechanism 12 and the three-axis walking surface support base 16 constitute a walking device, and the cord walking device is used in a space limited by a walking surface (belt) interlocked with a pedestrian's walking operation. It generates a feeling as if walking in a virtual three-dimensional large space including a slope or a remote real space, and is disclosed in Japanese Patent No. 292349 previously proposed by the present applicant.
No. 3 and Japanese Patent Application No. 11-7220 are described in detail, and here, to the extent necessary for understanding the present invention,
These will be described.

The three-axis walking surface support 16 supporting the belt mechanism 12 has a walking belt surface rotating mechanism and a two-axis walking belt surface posture holding mechanism. The walking belt surface rotating mechanism rotates the belt mechanism 12 about the axis J1 so that the belt mechanism 12 faces the course when the game player 14 changes course. The biaxial walking belt surface attitude holding mechanism is the axis J
It is rotatable around 2 and makes the belt mechanism 12 uphill or downhill, and rotates around the axis J3 to cancel the inertial force generated in the game player 14.

In front of the belt mechanism 12, an infrared camera 20 is used to measure the toe motion of the game player 14.
Is installed. Infrared reflective stickers 22 and 24 are attached to the tips of both feet of the game player 14. The infrared seals 22 and 24 reflect infrared light from an infrared lamp (not shown) that irradiates the vicinity of the foot of the game player 14 from the position of the infrared camera 20. And
The toe position information indicating the toe position of the game player 14 is acquired by the infrared camera 20 capturing the reflected light.

The position of the head of the game player 14
In order to measure the posture, the magnetic position / posture sensor 26
Attached to the head mount. The head mount may be of a headphone integrated type, in which case the game player 14 can hear external sounds (eg, game music and sound effects) through the headphones. Further, the game player 14
, The push button switch 28 is grasped. The push button switch 28 is used to reverse the traveling direction of the player object PO as described above, and is used to move the player object PO to the slope SL.
Operated to raise and lower. When the push button 28 is pressed to raise and lower the slope SL in the game screen, a signal is output from the computer 32 and the belt mechanism 12
Is moved up and down in accordance with the slope SL.

Further, in front of the game player 14,
A display 18 is provided. This display 18
Means CRT, PD (plasma display) or L
It may be a CD (liquid crystal display) or the like, and includes a speaker (not shown) that not only displays a game screen but also outputs game music and sound effects. Therefore, the game player 14 can check the video and audio of the game through the display 18.

The walking information detected by the infrared camera 20 and the head position / posture information detected by the magnetic position / posture sensor 26 are input to the computer 30. The computer 30 includes a toe position detecting function f1 and a head position detecting function f2. The directional speed detecting function f3 calculates a walking speed of the game player 14 based on the toe position and outputs walking speed information. And outputs head position / posture information according to the head position information.

Further, the computer 30 has a drive function f4 for driving the belt mechanism 12 and the three-axis walking surface holding mechanism 16, and the drive control function f5 is adapted to detect the walking speed detected by the walking speed detecting function f3. Based on this, the rotation of the belt mechanism 12 about the axis J1 (FIG. 2) is determined so that the standing position of the belt mechanism 12 on the belt of the game player 14 is always maintained at the center of the belt. The rotation of the belt is output from the drive control function f5 as walking direction information.

Further, an operation signal of the push button switch 28 operated by the game player 14 is given to another computer 32. The computer 32 includes a walking motion analysis / walking device control function f6. The walking motion analysis / walking device control function f6 includes walking speed information, head position / posture transmitted from the computer 30 via the transmission line 34. While receiving the information and the walking direction information, control information for controlling the walking device is transmitted to the computer 28 via the transmission line 34.

The transmission line 34 is an electric wire for transmitting an electric signal, an optical fiber for transmitting an optical signal, or the like, but may be a wireless transmission means using infrared rays, weak radio waves, or the like.

The walking motion analysis / walking device control function f6 includes:
The various types of information described above are passed to the screen information generation function f8 through the integrated management function f7. The integrated management function f7 manages and controls the entire system of the walking-type sensation game device 10, creates screen control information based on the walking information analyzed by the walking motion analysis / walking device control function f6, and creates a screen. In addition to the information generation function f8, when the game player 14 operates the push button switch 28, control information for raising and lowering the belt mechanism 12 is transmitted from the walking operation analysis / walking device control function f6 to the computer in accordance with the operation signal. This is given to 28 belt and support base drive function f4 and drive control function f5.

The screen information generating function f8 generates a video signal for displaying the horizontal passage HR, the slope SL, the player object OP, the enemy objects EP and EA, or the gold bar GI in the game screen shown in FIG. Give to display 18. However, this screen information generation function f
8 also creates an audio signal of a sound (game music or sound effect) to be output from a speaker (not shown) of the display 18, and gives it to the display 18.

For example, assuming that the walking speed of the game player 14 output from the computer 30, that is, the belt speed is Vw, the integrated management function f 7 calculates the walking speed Vw.
Is integrated over time, and the position information of the player object PO (FIG. 2) in the game screen is continuously updated. This position information is provided to the screen information generation function f8, and the screen information generation function f8
Change the display position of O.

The operation of the game of the embodiment shown in FIG. 1 will be specifically described with reference to FIGS. In the first step S1 in FIG. 4, drawing data is defined prior to the start of the game, and the computers 30 and 32 in FIG. 1 are initialized. It should be noted that the following description is an operation performed by the computer 32 unless otherwise specified.

[0029] In step S1, the main character (player object PO: 2) the position of the defined coordinates (X, Y), to define the position of the enemy EP shown in FIG. 2 with coordinates (x _N, y _N), Defined by the position coordinates (x _i , y _i ) of the enemy EA,
Is defined by coordinates (Gx _j , Gy _j ). Note that a preset fall distance difference is represented by dF, a preset enemy horizontal movement difference is represented by dx, and a preset enemy vertical movement difference is represented by dy.

In step S2, the computer 32
The surface data of the passages displayed on the display 18, that is, the respective horizontal passages HR and the slopes SL, that is, the respective numerals "1", "0", and "-1" in FIG. 3 are read.
The data of only the left slope is read in step S2 because the movable direction of each object is basically set from right to left on the screen as described above.

In the next step S3, the computer
It is determined whether the end flag is turned on. The end flag is turned on, for example, when the player object PO has acquired all the gold bars GI and reached the goal (step S37 in FIG. 6) or caught up by the enemy object EP or EA (step S54 in FIG. 8). Is done.
Therefore, if the end flag is turned on, the game ends at that point.

However, when all bullion GIs (objects) have been acquired, the game proceeds to the next game screen, that is, the stage, and when all stages are cleared, the game end flag may be turned on. When the game is overtaken, the life may be reduced, and the game end flag may be turned on when all the lives set in advance at the start of the game are exhausted.

If "NO" is determined in the step S3, that is, if the game is not ended yet, the computer 32 determines in step S4 that the enemy (automatic) EA
Calculate the move. This step S4 will be described later with reference to FIGS. 4, 10 and 11.

After step S4, in step S5, the computer 32 receives the above-mentioned walking speed and walking direction of the game player 14 from the computer 30, and also receives an operation signal from the push button switch 28, that is, a signal to raise and lower the slope. Although FIG. 1 shows only the walking device and the push button switch 28 of the game player 14 that controls the player object PO, the walking device and the push button switch for the game player that controls the enemy (player) EP. In step S5, the computer 32 naturally receives data or information therefrom.

In step S6, the movement of the hero (player object PO) or the enemy object EP is calculated based on each information or signal received in step S5. However, the calculation of the movement of the player object PO will be described later with reference to FIG. 6, and the calculation of the movement of the enemy object EP will be described later with reference to FIG.

In step S7, the computer 32
As shown in detail in a flowchart of FIG. 8 described later, the main character (player object PO) and the enemy object E
Determine contact with P and EA.

Further, in step S8, the computer 32 determines the contact between the hero (player object PO) and the bullion object GI, as shown in detail in the flowchart of FIG. 9 described later.

Then, in step S9, the computer 32 outputs a signal to the computer 30 for controlling the walking device as to whether or not the belt mechanism 12 should be moved up and down. That is, in response to the operation signal of the push button switch 28 of the game player 14 and the push button switch of another player that moves the enemy object EP read in the previous step S5, the belt mechanism 12 of the game player 14 and another corresponding Is given to the player's belt mechanism. For example, when an elevating signal for the belt mechanism 12 of the game player 14 is given to the computer 30, the computer 30 rotates the belt mechanism 12 around the axis J2 of the triaxial support 16, and moves the belt mechanism 12 uphill. Or go downhill.

Finally, in step S10, the computer 32 performs a drawing process of a hero, an enemy, a passage or the like based on the results of the processes in steps S4-S8.

Step S4 will be described in detail with reference to FIG. In a first step S11 in FIG. 5, the computer 30, as an initial state, and sets the number i of the enemy (auto) object EA to i = 0, sets the value dx set beforehand as a horizontal movement difference dx _i. Then, in step S12, it is determined whether or not the enemy (automatic) number i has reached the maximum value, that is, whether or not i = N-1, and if "YES", the process directly returns to the previous main routine (FIG. 4). .

If "NO" in the step S12, the enemy (automatic) number i is incremented (i = i +
1) Then, the process proceeds to step S14.

In step S14, it is determined whether the player object PO (main character) is in a certain height range, specifically, on the same horizontal passage or on another horizontal passage having the same height as the horizontal passage. Judge based on the coordinate position. Only when it is determined “YES” in step S14, the enemy (automatic) object EA is moved toward the position of the player object PO. In other words, the enemy (automatic) object EA is
Only when the player is at the same height (floor) as, the enemy (automatic) object EA is controlled to aim at the coordinates of the player object PO.

On the other hand, "NO" in step S14
Is determined, that is, the enemy (automatic) object EA
If is not at the same height (floor) as the player object PO, steps S16 to S18 are executed to randomly reverse the moving direction of the enemy (automatic) object EA. More specifically, a random number R equal to or less than "1" is generated in step S16, and whether or not the random number R is equal to or less than "0.5" is determined in step S17. If "YES" in step S17, then in step S18 outputting a turning signal (dx _i = -dx _i). When a forward slope is detected in step S19, steps S20 to S22 are executed, and when entering the block indicated by the numeral "1" in FIG. 3, the slope SL is moved up and down with a probability of 1/2.
Specifically, a random number R equal to or less than "1" is generated in step S20, and it is determined whether the random number R is equal to or less than "0.5" in step S21. If "YES" in step S21, then in step S22, according inclination of the slope to calculate the vertical movement difference dy _i for horizontal movement difference dx _i.

However, if "NO" is determined in step S14, and if it is determined in step S15 that the enemy (automatic) object EA is in the block having the number "-1" in FIG. 3, then in step S24 Vertical movement difference d
y _i is set to a predetermined fall distance difference −dF, and the horizontal movement difference dx _i is set to 0, and the camera is dropped on a horizontal passage immediately below.

Thereafter, in step S23, the coordinate position of the enemy (automatic) object EA is updated, and in step S12
Return to

After "YES" is determined in step S14, in step S25, the computer 3
2 indicates that the enemy (automatic) object EA _i has a slope S
It is determined whether it is on L.

When the vehicle is on the slope SL, step S2
In 6, the computer 32 controls the enemy (automatic) object EA so that the main character, ie, the object P
Move forward toward the plane where O is. Specifically, a subroutine shown in FIG. 10 is executed.

[0048] In a first step S71 in FIG. 10, computer 32, as an initial state, and sets the number i of the enemy (auto) object EA to i = 0, the value dx set beforehand as a horizontal movement difference dx _i Set. Then, in a step S72, it is determined whether or not the enemy (automatic) number i has reached the maximum value, that is, whether or not i = N−1. If “YES”, the process returns to FIG. If “NO” in the step S72, the enemy (automatic) number i is incremented (i = i + 1) in a step S73, and the process proceeds to the step S74.

In step S74, it is determined whether the difference between the coordinate Y of the player object PO and the coordinate y _i of the enemy (automatic) object EA _i is larger than zero (0), that is, whether the difference is positive (+) or negative (−). Judge. That is, in this step S74, the player object PO is determined to be the enemy (automatic) object EA _{i in} the height positional relationship between the two.
Determine if you are above or below.

"NO" in the step S74, that is, the enemy (automatic) object E is positioned above the player object PO.
When it is determined that there are A _i, with modified to reduce its height y _i in step S75, the step S
76, calculates the horizontal movement difference dx _i in accordance with the inclination of the slope SL. In step S74, “YE
S ", that is, when it is determined that there are enemies (auto) object EA _i below the player object PO, with modified to increase its height y _i in step S77, the in step S78, the slope of the slope SL The horizontal movement difference dx _i is calculated according to the following equation:
After 76 or S78, in step S79, the enemy (automatic) object EA _i according to the horizontal movement difference calculated previously.
Change the horizontal position x _i of

When "NO" is determined in the step S25 in FIG. 5, an enemy (automatic) object EA is made to track the player object PO in a step S27 as shown in detail in FIG.

In the first step S81 of FIG. 11, the initial state is set to the number i of the enemy (automatic) object
And sets to 0, set the value dx set beforehand as a horizontal movement difference dx _i. Then, in step S82, it is determined whether or not the enemy (automatic) number i has reached the maximum value, that is, whether or not i = N-1, and if "YES", the process returns to FIG. If "NO" in the step S82, the enemy (automatic) number i is incremented (i = i + 1) in a step S83, and the process proceeds to the step S84.

[0053] At step S84, the difference is zero (0) to the coordinates x _i of the coordinate X and that enemy (auto) object EA _i of the player object PO whether greater than, or positive (+) or negative (-) or Judge. That is, in step S84, in the horizontal positional relationship between the two,
Player object PO is an enemy (automatic) object E
Determine whether you are to the right or left of A _i .

"NO" in the step S84, that is, the enemy (automatic) object E is set to the right of the player object PO.
When it is determined that there are A _i, modified to gather the horizontal position x _i to the left at step S85. Conversely, “YES” in the step S84, that is, the player object P
When it is determined that the enemy (automatic) object EA _i is to the left of O, the horizontal position x _i is changed to move to the right in step S86.

Next, the motion calculation of the player object PO will be described with reference to FIG. In the first step S31, the computer 32 determines whether or not the block in which the player object PO exists at that time is “empty”, that is, a block having the number “−1” in FIG.

If "NO" is determined in the step S31, the moving speed of the player object PO in the horizontal forward direction is determined in a step S32 based on the walking speed data of the game player 14 previously captured in the step S5 in FIG. Determine dx.

For example, the horizontal position of the player object PO at a certain time t is expressed as X (t). The walking speed of the game program 14 at this time is defined as Vw (t). From these, the position X (t + Δt) of the player object PO at the time (t + Δt) is given by the following equation.

[0058]

X (t + Δt) = X (t) + S · Vw (t) · Δt where the coefficient S is the moving distance in the real space where the game player 14 is located and the player object P in the game screen.
This is a scale conversion coefficient for correspondence with the O movement distance.
The relationship between the walking speed of the game player and the moving speed of the player object can be arbitrarily set according to the magnitude of the scale conversion coefficient S. If the coefficient S is set to be large, the moving distance of the player object is relatively large compared to the walking distance of the game player, and if the coefficient S is small, the moving distance of the player object is relatively small relative to the walking distance of the game player. Become smaller. Therefore, the degree of difficulty of the game can be changed depending on how the coefficient S is set, and by setting the coefficient S according to the physical strength and fatigue of a person who is to be a game player, it is also possible to set an optimal amount of exercise for the person It is possible.

The horizontal position X calculated as described above
In order to move the player object PO by (t + Δt), the above-mentioned moving speed dx indicates how fast the player object PO should be moved.

In step S33 following step S32, the computer 32 determines whether or not the direction conversion flag is on, that is, whether or not the game player 14 has operated the push button switch 28. This step S3
If "YES" in step 3, data for direction conversion is created in step S34. That is, the horizontal movement difference dx of the player object PO is set to −dx. afterwards,
The process proceeds to step S35 in the same manner as when "NO" is determined in step S33.

In step S35, the computer 32
Indicates whether the elevating flag is on, that is, the game player 14 operates the push button switch 28 to
It is determined whether an instruction to move L up or down has been given. Step S35
Is "YES", it is determined in step S36 whether or not the player object PO is on the slope SL at that time. If "YES" in the step S36, a step S37 and a vertical movement difference dY according to the slope of the slope are calculated in a step S37 according to the horizontal movement difference dx.

When "NO" is determined in the step S35, that is, when the game player 14 has not instructed the elevation of the slope SL, or when "N" in the step S36.
If O ", that is, if the game player 14 has instructed to move up and down the slope but the player object PO is not on the slope, the process proceeds to step S38 as in the case where step S37 was executed, and determines whether or not the current position is the goal. .

If it is a goal, the end flag is turned on in step S39.
At 40, the position (X,
Y) is updated and the process returns to FIG.

When "YES" is determined in the step S31, that is, when the player object PO is "-
When it exists in the block of "1", in order to drop the player object PO on the horizontal passage immediately below, in step S40a, as the vertical movement difference dy,
A preset fall distance difference dF is set, and the process proceeds to step S38.

Next, a method of calculating the movement of the enemy (player) object EP will be described with reference to FIG. In the first step S41, the computer 32 determines whether or not the block in which the enemy (player) object EP at that time exists is a block having "empty", that is, a block having the number "-1" in FIG.

If "NO" is determined in the step S41, a horizontal forward of the enemy (player) object EP is determined in a step S42 based on the walking speed data of another game player previously captured in the step S5 in FIG. Is determined. However, since the method of determining the moving speed is the same as the calculation of the moving speed of the player object PO, the repetition is omitted.

In step S43 following step S42, the computer 32 determines whether or not the direction conversion flag is on, that is, whether or not another game player has operated the push button switch. If "YES" in this step S43, data for direction conversion is created in step S44. That is, the horizontal movement difference dx of the enemy (player) object EP is set to −dx. Thereafter, the process proceeds to step S45, similarly to the case where “NO” is determined in step S43.

In step S45, the computer 32
Determines whether the up / down flag is on, that is, whether another game player has operated the push button switch to instruct the up / down of the slope SL. If "YES" in the step S45, it is determined in a step S46 whether or not the enemy (player) object EP is on the slope SL at that time. If “YES” in the step S46,
In step S47, according to the horizontal movement difference dx,
The vertical movement difference dY and the step S according to the slope of the slope are calculated.

If "NO" is determined in the step S45, that is, if the game player 14 has not instructed the elevation of the slope SL, or if "N" in the step S46,
If O ", that is, if the game player 14 instructs the slope to go up and down, but the enemy (player) object EP is not on the slope, the process proceeds to step S48 as in the case of executing step S47, and the enemy (player) The position (X, Y) of the object EP is updated and FIG.
Return to

When "YES" is determined in the step S41, that is, when the enemy (player) object EP is present in the block of "-1", the enemy (player) object EP is dropped on the horizontal passage immediately below. Therefore, in step S49, the vertical movement difference d
A predetermined fall distance difference dF is set as y, and the process proceeds to step S48.

Referring to FIG. 8, a description will be given of the determination of contact between the hero and the enemy. In the first step S51 in FIG.
As an initial state, the computer 32 sets the number i of the enemy (automatic) object EA to i = 0. Then, in a step S52, it is determined whether or not the enemy (automatic) number i has reached the maximum value, that is, whether or not i = N-1, and if "YES", the process returns to FIG. If “NO” in the step S52, the enemy (automatic) number i is incremented (i = i + 1) in a step S53, and the process proceeds to the step S54.

[0072] At step S54, whether the position of the player object PO (X, Y) and their enemies (automatic) position of the object _{EA i (x i, y i} ) a difference between, i.e. less distance is a predetermined threshold value between the two Judge whether or not. That is, in this step S54, it is determined whether or not both are approaching each other exceeding a predetermined threshold. And "YE
If "S", the end flag is turned on in step S55, and the process returns to Fig. 4. If "NO", step S52.
To see the relationship between another enemy object and the player object.

With reference to FIG. 9, a description will be given of the contact determination of the hero with the gold nugget. First step S61 in FIG.
Then, the computer 32 sets the number j of the gold nugget object GI to j = 0 as an initial state. Then, in a step S62, it is determined whether or not the gold nugget number j has reached the maximum value, that is, whether or not j = K.
If "S", the process returns to FIG.
If “NO” in 2, the bullion number j is incremented (j = j + 1) in step S63, and the process proceeds to step S64. Note that the initial arrangement of such gold nugget objects is random.

In step S64, the position (X, Y) of the player object PO and its gold nugget object GI _j
It is determined whether the difference from the position (Gx _j , Gy _j ), that is, the distance between the two, is equal to or smaller than a predetermined threshold. That is, in this step S64, it is determined whether or not both are approaching each other exceeding a predetermined threshold. And “YES”
If so, the bullion object is erased from the screen in step S65, and the number of bullion is decremented (GN = GK-1) in step S66, and step S6 is performed.
At 7, it is determined whether or not the gold nugget number GN has become zero (0). If the number of gold nuggets is not zero, step S6
Returning to step 2, if it reaches zero, the process returns to FIG. 4 and turns on the end flag to end the game, or moves to the next stage (game screen).

As described above, in the walking type bodily sensation game device 10 of the embodiment of FIG. 1, the walking speed of the game player on the walking device (belt mechanism) can be approximated to the moving speed of the player object on the game screen. If the game player runs faster, the moving speed of the player object also increases. Further, when the slope SL of the game screen is moved up and down again, the situation in which the game player actually goes up and down the slope can be reproduced by inclining the belt mechanism 12. Therefore, the game outcome depends on the physical strength of the game player and the degree of consumption thereof, as well as a strategy such as which path to proceed. Therefore, the immersion feeling for the game is greatly improved as compared with a conventional game machine in which only a fingertip controls the game machine.

Further, according to the walking-type sensation game device 10, the difficulty of the game can be changed depending on the degree of correspondence between the movement of the game player and the player object or the walking speed (specifically, the conversion coefficient S). .
For example, in the case of a person or a small child who is not confident in physical strength, even if the game player moves the same one step, the villain character (enemy object) can easily move the player object two steps on the game screen. You can keep up. Further, the game time can be counted, and the timer function can be used to change the correspondence between the walking speed of the game player and the moving speed of the player object and how to reflect it.

Further, by connecting a plurality of walking devices via a communication line, it is possible to configure a network-sensation-type game device of several persons, for example, such as a “gold bullion excavation team” versus a “villain team”. is there. In that case,
The control of the enemy object can be controlled by the game player of the “villain team” in place of the program control in the embodiment.

In the above embodiment, the computer 3
Game player 1 input to computer 32 from 0
Although the head position / posture information of No. 4 is not particularly mentioned, this information can be used, for example, to produce a battle between the player object PO and the enemy objects EP and / or EA.

Similarly, the walking direction information was not actively used, but can be used instead of the follow-up button switch 28 for information for giving a direction change instruction.

Further, in the above embodiment, the game screen is displayed in two dimensions, but may be displayed in three dimensions having a depth direction.

Further, in the above-described embodiment, the game screen is displayed on the large flat display, but it may be displayed on a head-mounted display. In that case, if three-dimensional display is performed, the game player feels as if walking in a three-dimensional space. Further, a display device that covers the entire sky around the game player may be used. However, a large display may be used for a spectator, and a head-mounted display may be used like a game player.

Such a walking type bodily sensation game device is installed in a game facility such as a game center and enjoys purely as a game, or is installed in, for example, an exercise / training gym or a hospital to provide exercise / physical function training. It can be used as a machine or for rehabilitation for recovery of walking motion.
