FIG. 5 is a diagram showing functions of the game machine main body according to the first embodiment. This function is realized by the CPU 11 executing a game program stored in the DVD-ROM.
As shown in FIG. 5, the game machine body 200 (game machine body 10) includes a storage unit 201, a display control unit 202, a determination unit 203, a game control unit 204, a generation unit 205, and a determination unit 206.

  The storage unit 201 stores game images. In the present embodiment, the game image changes to an image (hereinafter referred to as a predetermined game image) intended to give a feeling of fear to the player at a predetermined timing. The predetermined timing may be a preset timing or a game event generation timing described later.

As the predetermined game image, for example, an image that darkens the background and produces an eerie atmosphere, an image that displays an effect object, or the like is used. The effect object is intended to give the player a feeling of fear, surprise, feeling irritated, and other psychological states (hereinafter collectively referred to as fear feeling, etc.). For example, objects such as monsters, monsters, and ghosts are used as effect objects.
Note that the storage unit 201 is realized by the function of the storage device 13.

The display control unit 202 displays the game image read from the storage unit 201 on the display screen of the monitor 20.
Further, the display control unit 202 displays a player object on the game image at an instruction position, which will be described later, pointed to by the controller 42.
The game image of the present embodiment shows a state when the virtual space is viewed from a predetermined viewpoint in a predetermined line-of-sight direction. Then, effect objects such as monsters are displayed in the virtual space.

Display examples of the game image are shown in FIGS. 6A and 6B. In the game images of each figure, a virtual space including the effect objects 70 and 71 as monsters and the player object 500 is represented. The player object 500 is displayed at the designated position P, and moves in the direction of arrow P1 in response to the operation of the controller 42 by the player. The effect objects 70 and 71 are moved in the directions of arrows 70a and 71a based on the game program. It is supposed to move.
Note that the player object 500 may be changed in shape or size, or may not be displayed. The moving speed, moving direction, expansion / reduction, movement of appearance / disappearance, the number of appearances, and the like of the effect object can be appropriately changed according to the scene. The field of view in the virtual space can also be adjusted according to scene settings such as daytime and nighttime.

Moreover, the fear gauge 60 mentioned later is arrange | positioned at the display screen of FIG. 6A and FIG. 6B.
The display control unit 202 is realized by the functions of the CPU 11 and the image processing unit 12.

  Next, the determination unit 203 will be described. The determination unit 203 determines the movement of the controller 42 during a predetermined period. In the present embodiment, the movement of the controller 42 is based on a change in the designated position on the display screen pointed to by the controller 42, and the determination unit 203 is realized by the functions of the CPU 11 and the storage device 13. As shown in FIG. 5, a position detection unit 2031 and a position determination unit 2032 are included.

The position detection unit 2031 indicates the indicated position on the display screen of the monitor 20 indicated by the controller 42 based on the position (space position) of the controller 42 and the direction (Z-axis direction in FIG. 3) of the tip (CCD camera 411). Is detected.
Specifically, the position detection unit 2031 is sent from the controller 42 based on the position of the controller 42 (space position of the CCD camera 411) and the direction of the tip (CCD camera 411) (Z-axis direction in FIG. 3). Images including two light emitting points are sequentially acquired. Then, the position detector 2031 sequentially detects the indicated position on the display screen based on the positional relationship between the two light emitting points.
The position detection unit 2031 is realized by the function of the CPU 11.

  The position determination unit 2032 determines a change in the designated position in a predetermined period based on the designated position detected by the position detection unit 2031. As the predetermined period, for example, a period from when a predetermined game image is displayed until a predetermined time elapses may be employed, or a period from when a game event described below occurs until a predetermined time elapses may be employed. May be. Further, as the predetermined period, for example, when an effect object is displayed on a predetermined game image, a period from when the effect object passes through a position in the virtual space until a predetermined time elapses is adopted. Also good.

  As a method for determining the change, whether the change in the indicated position is a normal change by comparing the displacement amount of the indicated position in a predetermined period with a threshold value set in the position determining unit 2032. Alternatively, there is a method for determining whether the change is abnormal. Here, the normal change means a change in the normal operation of the controller 42 by the player, and the abnormal change means a change caused by a reflex action caused by fear or the like given to the player.

For example, when a player views a predetermined game image (including a rendering object), the user may move his / her hand up and down due to fear or the like. In addition, when a player hears a predetermined game sound (a sound effect that gives a feeling of fear or the like, a target sound effect, BGM or the like), the player may move his / her hand up and down due to a feeling of fear or the like. . For example, the predetermined game sound is output in accordance with the display of the predetermined game image.
For example, the position determination unit 2032 determines that the change is abnormal when the displacement of the indicated position is greater than or equal to a threshold value.

  As the “displacement amount of the indicated position during the predetermined period”, the distance between the two points obtained from the two indicated positions at the start point and the end point of the predetermined period may be adopted or sequentially detected within the predetermined period. The maximum distance in the indicated position may be adopted.

Further, as a method of determining the change, for example, by determining whether or not the designated position P is in the normal area W as shown in FIG. 7, the change in the designated position is the normal change, or You may employ | adopt the method of determining whether it is an abnormal change. The normal area W in FIG. 7 represents the range of movement of the designated position expected in the case of normal operation of the controller 42 and is not displayed. For example, when the designated position exceeds the normal area W, the position determination unit 2032 determines that the change is abnormal. In this way, it is determined whether the change in the designated position is a normal change or an abnormal change. Note that the size, shape, and position of the normal region W may be changed according to the situation.
Such a position determination unit 2032 is realized by the functions of the CPU 11 and the storage device 13.

The game control unit 204 performs control to change the progress of the game based on the movement of the controller 42 determined by the position determination unit 2032 when a predetermined game image is displayed within the predetermined period. In the present embodiment, the game control unit 204, based on the change in the indicated position of the controller 42 determined by the position determination unit 2032 when a predetermined game image is displayed within the predetermined period, Control to change progress.
Here, “a case where a predetermined game image is displayed within a predetermined period” means that the game control unit 204 has a hand or arm caused by a sense of fear or the like given to a player who is in contact with the predetermined game image. This is because control for changing the progress of the game is performed based only on a change (abnormal change) in the indicated position caused by a reflex action such as the above. That is, in the case of an abnormal change that occurs in a situation unrelated to the game content, the game control unit 204 does not change the progress of the game.

  The determination of whether or not “when a predetermined game image is displayed within a predetermined period” may be performed by the game control unit 204 based on display conditions for displaying the predetermined game image. The determination unit 206 may perform the determination. As a display condition, for example, when a certain position in the virtual space is passed, a game event described later may occur, and when these conditions are satisfied, a predetermined game image is displayed. .

  Further, as control for changing the progress of the game, the predetermined game image is displayed every time a predetermined game image is displayed within a predetermined period determined to be an abnormal change or within a predetermined period determined to be an abnormal change. It is conceivable that the movement of the player object is limited for a certain time or the moving speed is slowed every time the number of times is displayed a predetermined number of times. It is also conceivable to reduce the number of attack items that can be used by the player object for a certain period of time. In other words, when a predetermined game image is displayed within a predetermined period determined to be an abnormal change, the game control unit 204 causes the game to be disadvantageous to the player based on the change in the indicated position (abnormal change). Change the progress of. Such control is performed in order to reflect the psychological state of the player, which is temporarily unable to make a normal determination due to fear or the like, in the action of the player object.

  The game control unit 204 is configured to perform control based on the distance between the effect object included in the predetermined game image and the designated position when performing control to change the progress of the game. The distance between the effect object and the designated position is calculated by, for example, coordinate values in three axis directions. For example, as the distance becomes shorter, the game control unit 204 can change the progress of the game gradually or step by step so that the depiction of the effect object becomes clear and disadvantageous to a player who has a fear or the like. . Accordingly, it is possible to adjust a situation that is disadvantageous to the player in accordance with the distance between the effect object and the designated position.

  Further, the game control unit 204 is configured to perform control based on the direction in which the effect object included in the predetermined game image is displayed when performing control to change the progress of the game. Such control is performed for the following reason. In other words, this is based on the fact that the effect object looks different depending on the direction in which the player views the effect object, and therefore the effect such as fear given to the player is different.

  In the present embodiment, for example, the game control unit 204 is configured to perform control based on the direction in which the effect object is displayed when the virtual space is viewed from a predetermined viewpoint in a predetermined line-of-sight direction. The line-of-sight direction is, for example, designated in advance by coordinate values in three axis directions. For this reason, the game control unit 204 compares the position where the effect object is displayed with the designated area of the line-of-sight direction, and the direction in which the effect object is displayed is in the line-of-sight direction depending on whether the position is in the designated area. You can judge whether or not.

Thereby, for example, when the effect object is displayed in the line-of-sight direction, the game control unit 204 changes the progress of the game so that it is disadvantageous to the player than when the effect object is displayed in the direction other than the line-of-sight direction. The situation that is disadvantageous to the player can be adjusted according to the direction when the effect object is viewed from the player.
Note that the game control unit 204 is realized by the functions of the CPU 11 and the storage device 13.

The generation unit 205 generates a game event (hereinafter referred to as an event). The event is for informing the display of a predetermined game image. As the event, for example, a game sound, an event object (event image) displayed in the virtual space, vibration of the controller 42 (vibration mechanism 427), or a combination thereof can be considered. The game sound may be output to the speaker 30 of the game machine body 10 or may be output to the speaker of the controller 42. As a result, the player can expect the appearance object to appear.
The generation unit 205 is realized by the functions of the CPU 11, the image processing unit 12, and the sound processing unit 14.

The determination unit 206 determines whether or not the predetermined game image or effect object is displayed.
Note that the determination unit 206 is realized by the function of the CPU 11.

  Furthermore, the function of each part will be described in detail. The display control unit 202 displays a predetermined game image when a game event is generated by the generation unit 205. Then, the position determination unit 2032 determines a change in the designated position based on the designated position detected before and after the occurrence of the event.

For example, when an event occurs at time t1 in FIG. 8, the display control unit 202 displays a predetermined game image including the effect object at time t2. Then, the position determination unit 2032 determines the change in the indicated position based on the indicated position in the predetermined period T from the time t1 to the time t3 when the predetermined time has elapsed. Thereby, the position determination unit 2032 can determine the change in the designated position at the timing when the effect object appears.
In the case of FIG. 8, the position determination unit 2032 uses t1 as the determination start point, but may use a time point before t1 as the start point.

  In addition, when the determination unit 206 determines that a predetermined game image has been displayed, the game control unit 204 performs control to change the progress based on a change in the designated position when the predetermined game image is displayed. It is configured as follows. Here, “change in designated position when a predetermined game image is displayed” is determined by the game control unit 204 based on the designated position in the frame of the predetermined game image.

Next, game control processing of the game system 100 will be described with reference to FIGS. 9 and 10. This game control process is realized by the CPU 11 executing a game program read from the DVD-ROM.
FIG. 9 is a flowchart showing the entire game control process when a predetermined game image is displayed in the game system 100. In FIG. 9, when the display control unit 202 (game machine main body) reads a game image from the storage unit 201 and displays it on the monitor 20, the determination unit 203 in the present embodiment causes the controller 42 in the predetermined period to As processing for determining movement, the processing of steps S11 and S12 is started.

  In the processing of step S11, the position detection unit 2031 (game machine main body) of the determination unit 203 indicates the indicated position on the display screen indicated by the controller 42 based on the position of the controller 42 operated by the player and the orientation of the tip. Is detected. Specifically, the position detection unit 2031 is sent from the controller 42 based on the position of the controller 42 (space position of the CCD camera 411) and the direction of the tip (CCD camera 411) (Z-axis direction in FIG. 3). Images including two light emitting points are sequentially acquired. Then, the position detector 2031 sequentially detects the indicated position on the display screen based on the positional relationship between the two light emitting points.

  Next, in the process of step S12, the position determination unit 2032 (game machine main body) of the determination unit 203 determines a change in the specified position in a predetermined period based on the specified position detected by the position detection unit 2031. In this determination, the position determination unit 2032 determines whether the change in the designated position is a normal change or an abnormal change.

Specifically, the position determination unit 2032 compares the displacement amount indicating the distance between the two points (between the start point and the end point indicated position of the predetermined period) detected by the position detection unit 2031 with a threshold value. If the amount of displacement is less than the threshold value, the position determination unit 2032 determines that the change in the indicated position is a normal change, and returns to the process of step S12.
On the other hand, if the displacement amount is equal to or greater than the threshold value, the position determination unit 2032 determines that the change in the indicated position is an abnormal change, and proceeds to the process of step S13.

  In step S13, the determination unit 206 (game machine body) determines whether or not a predetermined game image is displayed within a predetermined period of the change (abnormal change) determined in step S12. For example, the determination unit 206 determines whether a predetermined game image is displayed using the identification information of the game image. Thereby, it is possible to determine whether or not the change in the designated position is that when the predetermined game image is displayed.

  If it is determined that the predetermined game image is not displayed as a result of determination by the determination unit 206 (No in step S13), the process returns to step S13.

  On the other hand, when it is determined that it is displayed (Yes in step S13), the game control unit 204 (game machine main body), based on the change in the indicated position determined by the position determination unit 2032, that is, the abnormal change, Control to change the progress of the game is performed (step S14).

  In this case, the game control unit 204 changes the progress of the game so that the player is in a disadvantageous state. Possible disadvantageous conditions for the player include limiting the moving direction of the player object, limiting the use of attack items of the player object, and the like. Alternatively, the game control unit 204 extends the fear level gauge 60 (see FIGS. 6A and 6B) in accordance with the magnitude of the displacement, and when the fear level gauge 60 reaches a predetermined length, You may control to be in a disadvantageous state. As a result, the game control unit 204 changes the progress of the game based only on the abnormal change in the indicated position caused by the reflexive action caused by fear or the like given to the player in contact with the predetermined game image. Control can be performed. Therefore, the feeling of fear given to the player can be more accurately reflected in the game control.

  FIG. 10 is a flowchart showing the entire game control process when the effect object is displayed in the game system 100. In FIG. 10, when the display control unit 202 (game machine main body) reads out a game image including the effect object at a predetermined timing from the storage unit 201 and displays it on the monitor 20, the determination unit in the present embodiment. 203 starts the process of step S11A and S12A as a process which determines the motion of the controller 42 in a predetermined period.

  In the process of step S11A, the position detection unit 2031 (game machine body) of the determination unit 203 indicates the indicated position on the display screen indicated by the controller 42 based on the position of the controller 42 operated by the player and the orientation of the tip. Is detected. Specifically, the position detection unit 2031 is sent from the controller 42 based on the position of the controller 42 (space position of the CCD camera 411) and the direction of the tip (CCD camera 411) (Z-axis direction in FIG. 3). Images including two light emitting points are sequentially acquired. Then, the position detector 2031 sequentially detects the indicated position on the display screen based on the positional relationship between the two light emitting points.

  Next, in the process of step S12A, the position determination unit 2032 (game machine main body) of the determination unit 203 determines a change in the specified position during a predetermined period based on the specified position detected by the position detection unit 2031. In this determination, the position determination unit 2032 determines whether the change in the designated position is a normal change or an abnormal change.

For example, the position determination unit 2032 determines the position of the designated position based on the designated position detected before and after the occurrence of the event as shown in FIG. 8, that is, from the time t1 to the time t3 (predetermined period T). Determine change. Here, the position determination unit 2032 first compares the displacement amount indicating the distance of the detection position between the two points t1 and t3 in FIG. 8 with a threshold value. If the amount of displacement is less than the threshold value, position determination unit 2032 determines that the change in the indicated position is a normal change, and returns to the process of step S12A.
On the other hand, if the amount of displacement is equal to or greater than the threshold value, position determination unit 2032 determines that the change in the indicated position is an abnormal change, and proceeds to the process of step S13A.

  In step S13A, the determination unit 206 (game machine body) determines whether or not the effect object is displayed within a predetermined period of the change (abnormal change) determined in step S12A. For example, the determination unit 206 determines whether the effect object is displayed for each frame using the identification information of the effect object. Thereby, it can be determined whether or not the change in the designated position is that when the effect object is displayed.

  As a result of determination in the determination unit 206, when it is determined that the effect object is not displayed (No in step S13A), the process returns to step S13A.

  On the other hand, when it is determined that it is displayed (Yes in step S13A), the game control unit 204 (game machine main body), based on the change in the indicated position determined by the position determination unit 2032, that is, the abnormal change, Control to change the progress of the game is performed (step S14A).

  In this case, the game control unit 204 changes the progress of the game so that the player is in a disadvantageous state. Possible disadvantageous conditions for the player include limiting the moving direction of the player object, limiting the use of attack items of the player object, and the like. Alternatively, the game control unit 204 extends the fear level gauge 60 (see FIGS. 6A and 6B) in accordance with the magnitude of the displacement, and when the fear level gauge 60 reaches a predetermined length, You may control to be in a disadvantageous state. Thereby, the game control unit 204 performs control to change the progress of the game based only on the abnormal change in the indicated position caused by the reflexive action caused by fear or the like given to the player in contact with the effect object. It can be carried out. Therefore, the feeling of fear given to the player can be more reflected in the game control.

Further, the process of step S14A will be described in detail.
In step S14A, the game control unit 204 is in a disadvantageous state for the player based on the distance between the effect object determined to be displayed in step S13A and the change indication position determined to be abnormal in step S12A. Control to change the progress of the game is performed. For example, the game control unit 205 changes the progress of the game step by step so as to be disadvantageous to the player as the distance becomes shorter. Accordingly, it is possible to adjust a situation that is disadvantageous to the player in accordance with the distance between the effect object and the designated position.

  Further, in step S14A, the game control unit 204 controls to change the progress of the game so that the game object is in a disadvantageous state based on the direction in which the effect object determined to be displayed in step S13A is displayed. I do. For example, when the effect object is displayed in the line-of-sight direction, the progress of the game can be changed so as to be disadvantageous to the player compared to the case where the effect object is displayed in a direction other than the line-of-sight direction. Accordingly, it is possible to adjust a situation that is disadvantageous to the player in accordance with the direction in which the player views the effect object.

  Further, in step S14 or S14A, the game control unit 204 outputs a predetermined game sound (such as a sound effect intended to produce a feeling of fear, BGM, etc.) within the predetermined period (for example, the output destination is the speaker 30, When a speaker in the controller 42 is played, control for changing the progress of the game may be performed based on the abnormal change in the indicated position so as to be in a disadvantageous state for the player. Thereby, the game control unit 204 changes the progress of the game based on the abnormal change in the indicated position caused by the reflex action caused by the fear given to the player who has heard the predetermined game sound. Control can be performed. Therefore, the feeling of fear given to the player can be more accurately reflected in the game control.

Embodiment 2
Next, a second embodiment of the present invention will be described.
In the second embodiment, unlike the first embodiment in which the game machine body 10 performs game control using the indicated position indicated by the controller 42, the game control is performed using information from the acceleration sensor 426 of the controller 42. Do. In the second embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals and terms, and redundant description is appropriately omitted.

FIG. 11 is a diagram showing functions of the game machine body according to Embodiment 2 of the present invention. This function is realized by the CPU 11 executing a game program stored in the DVD-ROM.
A game machine main body 300 (game machine main body 10) in FIG. 11 includes a storage unit 201, a display control unit 202, a determination unit 203, a game control unit 302, and a determination unit 303.
In the present embodiment, the movement of the controller 42 determined by the determination unit 203 is based on the change in the acceleration of the controller 42 unlike the case of the first embodiment, and the determination unit 203 is shown in FIG. Thus, it is comprised by the acceleration determination part 301. FIG.

  The acceleration determination unit 301 sequentially acquires information supplied from the acceleration sensor 426 of the controller 42 and detects a change in acceleration of the controller 42 during a predetermined period. The information supplied from the acceleration sensor 426 includes acceleration data detected by the acceleration sensor 426 and its detection time. The acceleration data is in the triaxial direction, but may be biaxial or uniaxial.

Specifically, the acceleration determination unit 301 compares the acceleration data in a predetermined period with a threshold value set in the acceleration determination unit 301, so that the movement of the controller 42 is normal change or abnormal. Determine if it is a change. Here, the normal change means a change in the normal operation of the controller 42, and the abnormal change means a change caused by a reflexive action caused by a feeling of fear given to the player. As a result of the reflexive action, for example, when the player looks at the performance object, a case where the hand moves up and down unconsciously due to fear or the like can be considered.
The acceleration determination unit 301 is realized by the functions of the CPU 11 and the storage device 13.

The game control unit 302 changes the progress of the game based on the change (movement) of the acceleration of the controller 42 detected by the acceleration determination unit 301 when a predetermined game image is displayed within the predetermined period. Take control.
Specifically, when a predetermined game image is displayed within a predetermined period, the game control unit 302 advances the game based on a change (abnormal change) in acceleration of the controller 42 so as to be disadvantageous to the player. The situation can be changed.

As a control for changing the progress of the game, a predetermined game image is displayed every time a predetermined game image is displayed within a predetermined period determined to be an abnormal change or within a predetermined period determined to be an abnormal change. It is conceivable to limit the movement direction of the player object, limit the use of the attack item of the player object, etc., every time this is done a predetermined number of times. That is, when a predetermined game image is displayed within a predetermined period, the game control unit 302 changes the progress of the game so as to be disadvantageous to the player based on a change (abnormal change) in acceleration of the controller 42. It becomes possible to do.
Note that the game control unit 302 is realized by the function of the CPU 11.

  Note that “when a predetermined game image is displayed within a predetermined period” is the same as in the first embodiment. In other words, the game control unit 302 changes the progress of the game based only on the change in the acceleration of the controller 42 caused by the reflexive action caused by fear or the like given to the player in contact with the predetermined game image. This is to perform control. That is, in the case of an abnormal change that occurs in a situation unrelated to the content of the game, the game control unit 205 does not change the progress of the game.

  Further, the determination of whether or not “when a predetermined game image is displayed within a predetermined period” is the same as in the case of the first embodiment. In other words, the game control unit 302 may perform based on display conditions for displaying a predetermined game image, or may be performed by the determination unit 303 described later. As a display condition, for example, a case where an event occurs when a player object passes a certain position in the virtual space can be considered.

  As in the case of the game control unit 204 of the first embodiment, the game control unit 302 performs control to change the progress of the game, and the designated position detected by the effect object and the position detection unit 2031 in FIG. You may comprise so that control may be performed based on distance.

Similarly to the case of the game control unit 204 of the first embodiment, the game control unit 302 is configured to perform control based on the direction in which the effect object is displayed when performing control to change the progress of the game. May be.
Furthermore, when a predetermined game sound (for example, sound effect, BGM, etc.) is output (for example, the output destination is the speaker 30 or the speaker in the controller 42), the game control unit 302 changes the indicated position abnormally. Based on this, control may be performed to change the progress of the game so that the player is in a disadvantageous state.

The determination unit 303 determines whether or not a predetermined game image or effect object displayed by the display control unit 202 is displayed within a predetermined period determined by the acceleration determination unit 301.
Note that the determination unit 303 is realized by the function of the CPU 11.

Furthermore, the acceleration determination unit 301 and the display control unit 202 have the following functions.
The acceleration determination unit 301 acquires information (acceleration data, detection time) from the acceleration sensor 426 acquired before and after the occurrence of the event by the generation unit 205 and determines a change in acceleration of the controller 42.

  For example, in the case of FIG. 8, the acceleration determination unit 301 determines the controller 42 based on information (acceleration data, detection time) from the acceleration sensor 426 in a predetermined period T from a time t1 to a time t3 when a predetermined time has elapsed. Determine the change in acceleration. Thereby, the acceleration determination part 301 can determine the change of the acceleration of the controller 42 at the timing at which a predetermined game image (including the effect object) is displayed.

  In addition, when the determination unit 303 determines that the predetermined game image is displayed, the game control unit 302 changes the progress state based on the change in acceleration of the controller 42 when the predetermined game image is displayed. Is configured to do. Here, the “change in the acceleration of the controller 42 when the predetermined game image is displayed” indicates that the game control unit 302 receives information (acceleration data, detection time) from the acceleration sensor 426 in a period in the frame of the predetermined game image. ).

  In addition, the configuration of the game system 100 including the controller 42 is the same as that in the first embodiment.

Next, the game control process of the game system 100 according to the second embodiment will be described with reference to FIGS. This game control process is realized by the CPU 11 executing a game program read from the DVD-ROM.
FIG. 12 is a flowchart showing the entire game control process when a predetermined game image is displayed in game system 100 of the second embodiment. In FIG. 12, when the display control unit 202 (game machine main body) reads a game image from the storage unit 201 and displays it on the monitor 20, the determination unit 203 according to the present embodiment moves the controller 42 during a predetermined period. Is determined by the acceleration determination unit 301, and the process of step S21 is started.

  In the process of step S21, the acceleration determination unit 301 (game machine body) sequentially acquires information supplied from the acceleration sensor 426 of the controller 42, and determines a change in the acceleration of the controller 42 during a predetermined period. The information supplied from the acceleration sensor 426 includes acceleration data detected by the acceleration sensor 426 and its detection time.

Specifically, the acceleration determination unit 301 compares acceleration data for a predetermined period with a threshold set in the acceleration determination unit 301. Then, when the acceleration data is less than the threshold value, the acceleration determination unit 301 determines that the change in the acceleration of the controller 42 is a normal change, and returns to the process of step S21.
On the other hand, if the acceleration data is greater than or equal to the threshold value, the acceleration determination unit 301 determines that the change in the acceleration of the controller 42 is an abnormal change, and proceeds to the process of step S22.

  In step S22, the determination unit 303 (game machine body) determines whether or not a predetermined game image is displayed within the predetermined period determined to be an abnormal change in step S21. For example, the determination unit 303 determines whether a predetermined game image is displayed for each frame using the identification information of the game image. Thereby, it can be determined whether or not the change in the acceleration of the controller 42 is that when a predetermined game image is displayed.

  If it is determined that the predetermined game image is not displayed as a result of determination by the determination unit 303 (No in step S22), the process returns to step S22.

  On the other hand, when it is determined that it is displayed (Yes in step S22), the game control unit 302 (game machine main body) is based on a change in acceleration of the controller 42 determined by the acceleration determination unit 301, that is, an abnormal change. Then, control for changing the progress of the game is performed (step S23).

  In this case, the game control unit 302 changes the progress of the game so that the player is in a disadvantageous state. As a result, the game control unit 302 determines the progress of the game based only on the abnormal change in the acceleration of the controller 42 caused by the reflexive action caused by fear or the like given to the player in contact with the predetermined game image. Control to change can be performed. Therefore, the feeling of fear given to the player can be more accurately reflected in the game control.

  FIG. 13 is a flowchart showing the entire game control process when the effect object is displayed in the game system 100 of the second embodiment. In FIG. 13, when the display control unit 202 (game machine body) reads a game image from the storage unit 201 and displays it on the monitor 20, the determination unit 203 in the present embodiment causes the movement of the controller 42 during a predetermined period. Is determined by the acceleration determination unit 301, and the process of step S21A is started.

  In the process of step S21A, the acceleration determination unit 301 (game machine body) sequentially acquires information supplied from the acceleration sensor 426 of the controller 42, and determines a change in the acceleration of the controller 42 during a predetermined period. The information supplied from the acceleration sensor 426 includes acceleration data detected by the acceleration sensor 426 and its detection time.

Specifically, the acceleration determination unit 301 compares acceleration data for a predetermined period with a threshold set in the acceleration determination unit 301. Then, when the acceleration data is less than the threshold value, the acceleration determination unit 301 determines that the change in the acceleration of the controller 42 is a normal change, and returns to the process of step S21A.
On the other hand, if the acceleration data is greater than or equal to the threshold value, the acceleration determination unit 301 determines that the change in the acceleration of the controller 42 is an abnormal change, and proceeds to the process of step S22B.

  For example, the acceleration determination unit 301 is based on information (acceleration data, detection time) from the acceleration sensor 426 acquired from the time point t1 to the time point t3 (predetermined period T) as shown in FIG. Then, a change in acceleration of the controller 42 is determined.

  In step S22A, determination unit 303 (game machine body) determines whether or not the effect object is displayed within the predetermined period determined to be abnormal change in step S21A. For example, the determination unit 303 determines whether an object is displayed for each frame. Thereby, it can be determined whether the change in the acceleration of the controller 42 is the one when the effect object is displayed.

  As a result of determination in the determination unit 303, when it is determined that the effect object is not displayed (No in step S22A), the process returns to step S22A.

  On the other hand, when it is determined that it is displayed (Yes in step S22A), the game control unit 302 (game machine body) is based on the change in acceleration of the controller 42 determined by the acceleration determination unit 301, that is, an abnormal change. Then, control for changing the progress of the game is performed (step S23A).

  In this case, the game control unit 302 changes the progress of the game so that the player is in a disadvantageous state. Thereby, the game control unit 302 changes the progress of the game based only on the abnormal change in the acceleration of the controller 42 caused by the reflexive action caused by the fear or the like given to the player in contact with the effect object. Control can be performed. Therefore, the feeling of fear given to the player can be more accurately reflected in the game control.

  As in the case of the first embodiment, the game control unit 302 determines whether the game is based on the distance between the effect object and the indicated position, the direction in which the effect object is displayed, or a combination thereof in step S23 or S23A. You may make it perform control which changes a progress condition. In this way, it is possible to adjust a situation that is disadvantageous to the player according to the distance between the effect object and the designated position and the direction in which the player views the effect object.

  Furthermore, in step S23 or S23A, the game control unit 302, when a predetermined game sound (for example, sound effects, BGM, etc.) is output (for example, the output destination is the speaker 30 or the speaker in the controller 42), the controller Based on the abnormal change in the acceleration of 42, control may be performed to change the progress of the game so that the player is in a disadvantageous state. Thereby, the game control unit 302 controls to change the progress of the game based on the abnormal change in the acceleration caused by the reflex action caused by fear or the like given to the player who heard the predetermined game sound. It can be performed. Therefore, the feeling of fear given to the player can be more accurately reflected in the game control.

In the first and second embodiments, the case where the feeling of fear given to the player is reflected in the game control by the indicated position indicated by the controller 42 or the information from the acceleration sensor 426 has been described. It is not limited.
For example, even when the player presses a button (B button 414 or the like) of the controller 42 after an event occurs, the pressing can be interrupted for a moment due to fear or the like.
Therefore, the CPU 11 (pressing detection unit) detects a change in pressing after the occurrence of the event. For example, when the pressing time interval is equal to or greater than the reference interval, the CPU 11 (pressing detection unit) detects an abnormal operation. Then, the game control unit may change the progress of the game so as to be in a disadvantageous state for the player when the effect object is displayed during the abnormal operation (predetermined period).

  Further, the hardware configuration and game control processing sequence in practice may be changed without departing from the spirit of the present invention. For example, the game machine main body 200 of the first embodiment and the game machine main body 300 of the second embodiment may be applied in combination. In this case, the game control unit may change the progress of the game so that the player is in a disadvantageous state when both the change in the indicated position and the change in the acceleration of the controller 42 are abnormal.

  Further, the case where one player plays using the controller 42 has been described, but two or more players may play.

  Moreover, although the game machine main body 10 (CPU 11) demonstrated the case where the game program read from DVD-ROM was performed, you may make it run the game program delivered via communication networks, such as the internet.
