It is.
The fifth invention is the game system according to any one of the first to fourth inventions, wherein the screen (2) is arranged in a cylindrical shape or a spherical shape so as to surround the player. It is a game system.

According to the present invention, the following effects can be obtained.
-1st invention projects a play screen centering on the aim of an input device from an input device projection part, and a play progresses as the center of a play screen was selected based on operation of an operation part. For this reason, it is possible to always generate the play screen so that the aiming direction aimed by the player is at the center. This makes it possible to accurately determine the aim without using a conventional structure in which a light emitting element is provided in an input device and a photosensor or the like is provided on the screen side.
In addition, since the present invention is provided with a screen and the player plays with the player positioned at a predetermined position, the play screen can be projected in a direction in which the screen is surely present.
In the present invention, since the input device is arranged at a position different from the game machine and connected to the game machine so as to be communicable, the input device can be reduced in size and weight, so that the player can easily hold it, Player fatigue can be reduced.
In the second invention, since a part of the play screen of the game machine projection unit matches the play screen of the input device projection unit, the play screen can be projected even if the input device is not directed to the screen. Here, when only the input device projection unit is provided, the player must always point the input device toward the screen in order to check the play screen. In the present invention, this is not necessary, and the player's fatigue can be further reduced.
In the present invention, the game machine projection unit has a larger projection angle than the input device projection unit. For this reason, a play screen larger than an input device projection part can be projected, and force can be improved. The game machine projection unit has a lower resolution than the input device projection unit. That is, when the player points the input device toward the screen, the play screen of the high-resolution input device projection unit is configured to overlap the play screen of the low-resolution game machine projection unit. For this reason, it is possible to reduce the cost of the game machine projection unit, and the screen on which the player actually plays can be displayed with high resolution, so that the quality of play can be maintained.

(Embodiment)
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a top view (FIG. 1A) of the game system 1 of the embodiment, and a perspective view (FIG. 1B) viewed from the front side Y1.
The game system 1 is a large-sized device installed in a store such as a game center, and is a device that performs a gun shooting game in which a player fights against a monster M (enemy) while moving in a virtual space.
The game system 1 includes a screen 2, a game machine 10, and a controller 50.
The screen 2 is a large-sized screen 2 having a semi-cylindrical surface with a radius of, for example, 2 m or more. The screen 2 has a semicylindrical shape, and is arranged so that the central axis of the semicylindrical is in the vertical direction Z. The player is positioned on the central axis of the semi-cylinder and is played while being surrounded by the screen 2.
The screen 2 is a translucent member, and the play screen 60 can be observed from the near side Y1 regardless of whether the play screen is projected from either the back side Y2 (back side) or the near side Y1.

FIG. 2 is a block diagram of the game system 1 of the embodiment.
FIG. 3 is an external view of the controller 50 according to the embodiment.
The game machine 10 includes a game machine side projector 11 (game machine projection device), a storage unit 20, and a control unit 30.
The game machine side projector 11 is a projector that projects the game machine side play screen 61 from the back side Y2 of the screen 2. The game machine side projector 11 is connected to the game machine 10 main body by an electric cable (not shown). The game machine side projector 11 projects a play screen on the entire screen 2. Therefore, the game machine side projector 11 enlarges the screen using a special lens. Therefore, the game machine side projector 11 has a larger projection angle than a controller side projector 52 described later, but has a lower resolution than the controller side projector 52.

The storage unit 20 is a storage device such as a hard disk or a semiconductor memory element for storing programs, information, and the like necessary for the operation of the game system 1. The storage unit 20 includes a game program 21.
The game program 21 is a program for progressing this shooting game. The game program 21 incorporates three-dimensional virtual space information 21a that is a game space.

The control unit 30 is a control device for comprehensively controlling the game system 1 and is configured by, for example, a CPU (central processing unit). The control unit 30 reads and executes various programs stored in the storage unit 20 as appropriate, thereby realizing various functions according to the present invention in cooperation with the hardware described above.
The control unit 30 includes a play screen generation unit 31 and a play progression unit 32.
The play screen generation unit 31 is a control unit that controls the game machine side projector 11, the controller side projector 52 (described later), and controls the play screen to be projected based on the virtual space information 21a. The play screen generation unit 31 generates a video in the virtual space from the viewpoint of the player as a play screen 60 when the player moves in the virtual space.
The play progression unit 32 is a control unit for comprehensively controlling the progress of the game. The play advancing unit 32 advances a play in which the player moves in the virtual space. That is, in this game, the game machine 10 side determines a route along which the player moves in the virtual space.

The controller 50 is an input device operated by the play for playing.
As shown in FIG. 3, the controller 50 and the game machine 10 are connected by an electric cable 40 so that they can communicate with each other. For this reason, the controller 50 does not require a control device and a storage device for proceeding with the game, and can be reduced in size and weight. For this reason, it is easy for the player to grip, and the player's fatigue can be reduced. In the embodiment, power is supplied from the game machine 10. For this reason, the controller 50 does not need to be provided with a power source such as a battery, and can be further reduced in size and weight.

The controller 50 includes a case 50a, an angle detection unit 51, a controller side projector 52 (input device projection unit), and a trigger 53 (operation unit).
The case 50 a is a housing for the controller 50. The case 50a has a shape simulating a gun. The player holds the case 50a so as to hold a gun, and uses the direction in which the muzzle is facing as an aim.
The angle detection unit 51 is an angular velocity sensor that detects the aim by detecting the directions of the muzzle in the left-right direction X and the vertical direction Z.

The controller side projector 52 is a small projector accommodated in the case 50a. The controller side projector 52 projects the controller side play screen 62 on the screen 2 from the near side Y1. The controller side projector 52 is provided so that the center of the projection direction coincides with the direction aim of the muzzle, and projects the controller side play screen 62 (play screen) on the screen 2 at a fixed projection angle. That is, the controller-side projector 52 projects the controller-side play screen 62 in the direction in which the controller 50 is facing. The controller-side projector 52 has a smaller projection angle than the game machine-side projector 11. For this reason, the controller side projector 52 has a higher resolution than the game machine side projector 11.
Further, as described above, the screen 2 has a cylindrical shape, and the player is positioned substantially at the center of the cylinder. For this reason, the controller side projector 52 can project a high-quality play screen because the projection distance can be made almost constant.

  The trigger 53 is a lever operated by the player when aiming and firing a bullet in the virtual space. The trigger 53 includes a switch having an electrical contact, and outputs operation information to the game machine 10.

Next, the operation of the game system 1 will be described.
FIG. 4 is a flowchart showing the operation of the game system 1 of the embodiment.
5 and 6 are diagrams illustrating a play screen 60 according to the embodiment.
First, in step S (hereinafter referred to as “S”) 1, when the player inserts a coin into the coin insertion slot of the game machine 10, the control unit 30 starts processing. At the start of play, the player is fired at the center of the screen 2 to initialize the orientation reference of the controller 50.
In S2, the play screen generation unit 31 generates a game machine side play screen 61 that can be projected on the entire screen 2 based on the virtual space information 21a.
In S <b> 3, the play screen generation unit 31 projects the game machine side play screen 61 from the game machine side projector 11 onto the screen 2. Note that the game machine-side play screen 61 has a rough image because the resolution is low. For this reason, the player can only grasp the outline of the object in the play screen.

  In S <b> 4, the play screen generation unit 31 determines the direction of the controller 50 based on the output of the angle detection unit 51 and calculates the aim. This calculation is performed based on the output of the angle detection unit 51 of the controller 50 from the position initialized in S1, and the calculation accuracy is lowered. That is, in this process, it is only necessary to determine the orientation of the controller 50 with respect to the screen 2 to some extent.

In S5, the play screen generation unit 31 determines whether or not the inclination of the controller 50 in the vertical direction Z is equal to or greater than a specified angle based on the determination result in S4. The specified angle is an angle at which the controller 50 is tilted to the extent that the controller-side play screen 62 of the controller-side projector 52 deviates from the screen 2.
When the play screen generation unit 31 determines that the inclination in the vertical direction Z is equal to or greater than the specified angle (S5: YES), the play screen generation unit 31 proceeds to S6, whereas when determined to be equal to or less than the specified angle (S5: NO), Proceed to S5a.

In S5a, the play screen generation unit 31 continues to be off when the controller-side projector 52 is off, and turns off when the controller-side projector 52 is on. Accordingly, when the controller 50 is tilted to the extent that the controller-side play screen 62 is projected outside the screen 2, the controller-side projector 52 is turned off. Thereafter, the control unit 30 proceeds to S11.
Thereby, for example, when the controller 50 is directed downward so that the player lowers the gun, unnecessary projection from the controller-side projector 52 can be suppressed.

In S6, the play screen generation unit 31 generates a controller-side play screen 62 projected by the controller-side projector 52 based on the virtual space information 21a.
As shown in FIG. 5, the center of the controller-side play screen 62 is always the aim 62a. Further, the controller side projector 52 has a narrower projection angle than the game machine side projector 11. For this reason, a part of the game machine side play screen 61 of the game machine side projector 11 coincides with the controller side play screen 62 of the controller side projector 52.

  Here, during play, the game machine 10 always projects the game machine-side play screen 61 even if the controller 50 is not directed to the screen 2. For this reason, the player does not need to point the controller 50 at the screen 2 in order to check the play screen. Thereby, the game system 1 can reduce a player's fatigue.

In S <b> 7, the play screen generation unit 31 projects the controller-side play screen 62 from the controller-side projector 52.
As shown in FIG. 5, the controller-side play screen 62 is thereby superimposed on the game machine-side play screen 61. Since the controller-side play screen 62 has high resolution, the player can enjoy playing with high image quality in an area where the line of sight is actually facing.
Moreover, the game machine side play screen 61 is a rough thing which can recognize only the outline grade. For this reason, the controller-side play screen 62 is superimposed on the game machine-side play screen 61, and the player can observe the display on the controller-side play screen 62 with high quality even if the two images do not completely match. . For this reason, the detection accuracy of the direction of the controller 50 in S4 may be low.
In order to make the controller-side play screen 62 higher quality, the luminance of the game machine-side play screen 61 may be lower than that of the controller-side play screen 62.

In the scene shown in FIG. 6A, a case where the player places the aim 62a on the monster M will be described.
As long as the play continues (S11: NO), the processing from S2 is repeated. For this reason, when the player changes the orientation of the controller 50 and attempts to align the aim 62a with the monster M, the play screen generation unit 31 continuously updates the controller-side play screen 62 according to the orientation of the controller 50. . Thereby, the screen is smoothly connected and updated from FIG. 6A to FIG. 6B.
Therefore, if the monster M exists in the controller-side play screen 62, the player can track the monster M even if it moves.
On the other hand, as shown in FIG. 5, even if the monster M is outside the play screen and exists in the game machine side play screen 61, the game machine side play screen 61 is unclear. The presence of Monster M can be confirmed. For this reason, the player can catch the monster M by changing the direction of the controller 50 so that the monster M is included in the controller-side play screen 62. Note that the play screen generation unit 31 may blink or make a conspicuous color so that the monster M can be easily confirmed even if it is unclear.

  In S8, the play advancing unit 32 determines whether or not the trigger 53 has been operated. When it is determined that the trigger 53 has been operated (S8: YES), the play advancing unit 32 proceeds to S9, whereas when it is determined that the trigger 53 has not been operated (S8: NO), Proceed to S11.

  In S9, the play advancing unit 32 confirms the controller-side play screen 62, and when the trigger 53 is operated, that is, when the center of the controller-side play screen 62 is selected, the controller-side play screen 62 is displayed. It is determined whether or not there is a monster M in the center.

In this case, the play progression unit 32 determines only whether or not the monster M is in the center of the controller-side play screen 62 regardless of the orientation of the controller 50. For this reason, it is not necessary to determine the correct orientation of the controller 50, and it can be determined whether the aim 60a is aligned with the monster M.
For example, in the conventional gun shooting game, in order to determine the orientation of the controller, an infrared light emitting diode is provided in the controller 50 and a photo sensor is provided around the monitor. For this reason, the structure is complicated, and the process for determining the aim is complicated.
On the other hand, the game system 1 of the embodiment does not require these sensors and the like, has a simple structure, and is easy to process.

When it is determined that there is a monster M in the center (S9: YES), the play progression unit 32 proceeds to S10. On the other hand, when it is determined that there is no monster M in the center (S9: NO), the play progression unit 32 proceeds to S11. move on.
In S <b> 10, the play progression unit 32 processes the game as a hit and advances the play. That is, the play progression unit 32 takes away the physical strength of the monster M or gives a score to the player.

In S11, the play progression unit 32 determines whether or not to end the play due to the end of the play time or the like. When it is determined that the play is to be ended (S11: YES), the play advancing unit 32 proceeds to S12. On the other hand, when it is determined that the play is not to be ended (S11: NO), that is, when it is determined that the play is to be continued. Repeats the process from S2.
In S12, the control unit 30 ends the series of processes.

As described above, the game system 1 according to the embodiment plays with the player positioned at a predetermined position, so that the controller-side play screen 62 can be projected in the direction in which the screen 2 is surely present.
In addition, since the game system 1 includes the game machine-side projector 11, the game machine-side play screen 61 can be projected even when the controller 50 is not directed to the screen 2, and fatigue during play can be further reduced.
Furthermore, since the game system 1 is arranged so that the screen 2 surrounds the player, for example, a play in which enemies come from the left and right can proceed and the power can be improved.
