Description

  The present invention relates to a program, an information storage medium, and a game system.

2. Description of the Related Art Conventionally, game systems that perform input using a remote controller equipped with an acceleration sensor are known (see, for example, Patent Document 1). In such a game system, a controller movement mode or the like is calculated from the output value of the acceleration sensor, and game processing is performed in accordance with the calculated controller movement mode. For example, Patent Document 1 describes that when the vertical movement of the controller is calculated from the output value of the acceleration sensor, control for causing the wings of the object to flutter up and down is performed.
JP 2007-282787 A

  By the way, when determining whether or not the controller has been moved in a predetermined movement mode, if the movement start position is different, the output value (acceleration vector) output from the acceleration sensor during the movement of the controller also becomes a different value. Therefore, there may be a case where the input is not recognized even though the controller is moved in a correct manner. For example, when a circular locus is drawn by the controller, the output value of the acceleration sensor differs between drawing a circular locus from the top and drawing a circular locus from the bottom.

  In order to prevent the occurrence of such a situation, a method of fixing the movement start position and movement end position of the controller may be considered, but this is not preferable because the movement mode of the controller that can be used in the game is limited. .

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a program, an information storage medium, and a game system that can appropriately recognize the movement mode of the controller regardless of the movement start position of the controller. is there.

  (1) The present invention is a game system for a game in which input is performed using a controller having a sensor that detects a physical quantity whose value changes according to movement, and is associated with a predetermined movement mode of the controller. An output in which a given relationship is established between the storage unit that stores the plurality of reference data and the reference data in the plurality of reference data within the input reception period for receiving the input according to the predetermined movement mode A determination unit that determines whether or not a value is output from the sensor in any one of a plurality of predetermined orders; and the predetermined movement mode when it is determined that the value is output to the determination unit The present invention relates to a game system that includes a game processing unit that receives an input from and performs a game process.

  The present invention also relates to a program that causes a computer to function as each of the above-described units, and a computer-readable information storage medium that stores a program that causes the computer to function as each of the above-described units.

  In the present invention, whether or not an input according to a predetermined movement mode of the controller has been accepted is determined based on a plurality of predetermined output values that establish a given relationship with each reference data in the plurality of reference data. Judgment is made based on whether or not the signals are output from the sensor in any order. Therefore, according to the present invention, even if the movement start position of the controller is different, output values that establish a given relationship with each reference data are in any one of a plurality of predetermined orders. Since the input is accepted if it is output from the sensor, the movement mode of the controller can be recognized regardless of the movement start position of the controller.

  (2) In the game system, the program, and the information storage medium of the present invention, a determination unit that determines the plurality of reference data based on an output value of the sensor when the controller moves in the predetermined movement mode. Further, it may be included.

  In this way, a plurality of reference data suitable for a player who moves the controller in a predetermined movement mode can be set.

  (3) In the game system, the program, and the information storage medium of the present invention, the game processing unit causes the display unit to display an instruction mark that instructs the player to move the controller in the predetermined movement mode. May be.

  This makes it possible to notify the player of the timing for moving the controller in a predetermined movement mode.

  (4) The game system, the program, and the information storage medium of the present invention further include a sound control unit that controls the reproduction of the music, and the game processing unit displays the instruction sign on the display unit in accordance with the reproduction of the music. While displaying, the character which performs the dance linked | related with the said predetermined movement mode of the said controller may be displayed on a display part.

  (5) In the game system, program, and information storage medium of the present invention, the physical quantity detected by the sensor is an acceleration vector of the controller, and the value of each reference data in the plurality of reference data is at least 1 An acceleration vector in the axial direction may be used.

  (6) In the game system, program, and information storage medium of the present invention, the predetermined movement mode may be a circle movement locus, and the coordinates of the plurality of reference data may be four-fold rotationally symmetric.

  “Rotational symmetry” means that the movement trajectory (coordinates) is the same before and after rotation when the movement trajectory (coordinates) is rotated around the axis. When the movement locus (coordinates) is rotated in the range of 0 to 360 degrees around the axis, the movement locus (coordinates) coincides four times.

  In this way, the movement mode of the controller 16 can be properly recognized regardless of the inclination (orientation) of the controller 16 with the axis direction when the controller is moved along a circular movement locus as the rotation axis.

  Hereinafter, an embodiment of the present invention (this embodiment) will be described.

In this case, for example, an image sensor (light receiving element) such as a CMOS sensor or a CCD is provided in the controller 16, and a light source such as an LED provided on the indication surface (near the indication surface) is imaged by the image sensor. The indicated position of the controller 16 with respect to the indication surface may be obtained from the position information of the light source and the preset reference position information on the imaging side.

  The controller 16 may further be provided with buttons, levers, microphones, trackballs, touch panels, and the like. Further, the controller 16 may be one that the player holds and moves, or one that the player wears and moves.

  An information storage medium 180 (a computer-readable medium) stores programs and data (specifically, programs and data for causing a computer to function as each unit of the present embodiment), and the functions thereof are as follows. It can be realized by hardware such as an optical disk (CD, DVD, etc.), a magneto-optical disk (MO), a magnetic disk, a hard disk, a magnetic tape, or a memory (ROM).

  The storage unit 170 is a work area such as the processing unit 100 or the communication unit 194, or a storage area for programs and data developed from the information storage medium 180. The function is realized by hardware such as RAM (VRAM). it can. The storage unit 170 includes a main storage unit 172, a reference data storage unit 174, and a drawing buffer 176. The reference data storage unit 174 includes a plurality of reference items associated with a predetermined movement mode of the controller 16. Data is stored.

  The display unit 190 (display 19) outputs an image generated by the processing unit 100, and functions thereof are a CRT display, LCD (liquid crystal display), OELD (organic EL display), and PDP (plasma display panel). , A touch panel display, or an HMD (head mounted display).

  The sound output unit 192 outputs the sound generated by the processing unit 100, and the function can be realized by a speaker, headphones, or the like.

  The communication unit 194 is for communicating with the outside (server, other game system 1, etc.) via a network, and functions thereof are hardware such as various processors or communication ASICs, programs, and the like. Can be realized.

  Note that a program or data for causing a computer to function as each unit of the present embodiment may be distributed from the information storage medium of the server to the information storage medium 180 (storage unit 170) via the network and the communication unit 194. Good. Use of such server information storage media is also within the scope of the present invention.

  The processing unit 100 (processor) performs various processing such as game processing, image generation processing, or sound generation processing based on operation information from the controller 16 or programs and data developed from the information storage medium 180 to the storage unit 170. Processing is performed using the main storage unit 172 of the storage unit 170 as a work area. As the game process, for example, a process for starting a game when a game start condition is satisfied, a process for advancing the game, a process for placing an object such as a character or a map, a process for displaying an object, and a game result are calculated. A process or a process of ending the game when the game end condition is satisfied is performed. The function of the processing unit 100 can be realized by hardware such as various processors (CPU, DSP, etc.), ASIC (gate array, etc.), and programs.

  The processing unit 100 includes a sound control unit 110, a game processing unit 112, a determination unit 114, a determination unit 116, and a drawing unit 140. Note that some of these may be omitted.

  The sound control unit 110 performs sound processing based on the results of various processing (game processing) performed by the processing unit 100, generates game sound (music, BGM, sound effect, etc.), and outputs the game sound to the sound output unit 192. Let Specifically, reproduction control of game sounds (music, BGM, sound effects, etc.) of sound data read from the information storage medium 180 to the main storage unit 172 is performed. For example, in the case of a music performance game, the music corresponding to the game stage is played at the start of the game.

  The game processing unit 112 performs display control of an image (object image) displayed on the display unit 190. Specifically, an instruction sign (an instruction sign for instructing the player 20 to move the controller 16 in a predetermined movement mode), a character, a moving object (a car, an airplane, etc.), a building, a tree, a pillar, a wall, a map ( Display control such as generating an object to be displayed (such as terrain), instructing the display and display position of the object, and erasing the object. That is, display control is performed such as registering the generated object in the object list, transferring the object list to the drawing unit 140, and deleting the disappeared object from the object list. For example, in the case of a music performance game, an indication indicator for instructing the player 20 to move the controller 16 in a predetermined movement mode (movement trajectory) in accordance with the reproduction of the music is displayed on the display unit 190 and the controller 16 Display control is performed to display on the display unit 190 a character performing a dance associated with the movement mode.

  In addition, when the movement or movement of an object (a display object defined by two-dimensional data or three-dimensional data) occurs, the game processing unit 112 displays an image indicating the generated movement or movement on the display unit 190. Control for. Specifically, based on operation information from the controller 16, a program (movement algorithm), various data (motion data), and the like, processing for moving the display object and processing for operating the display object are performed. More specifically, the movement information (position, rotation angle, speed, or acceleration) of the display object and the operation information (position, rotation angle, or shape of each part) are sequentially sequentially for each frame (1/60 second). Perform the requested process. Note that a frame is a unit of time for performing processing for controlling movement and operation of a display object and drawing processing for generating an image.

  In addition, when it is determined that the game processing unit 112 has output to the determination unit 114 described below, the game processing unit 112 receives an input according to a predetermined movement mode of the controller 16 and performs a game process. For example, in the case of a music performance game, processing for updating the score parameter, processing for updating a parameter for controlling the progress of the game (a parameter for determining whether the game can be continued or cleared), and the like are performed. Further, for example, the character is caused to perform a dance associated with a predetermined movement mode of the controller 16. In addition, for example, in a fighting game in which winning or losing is determined according to a character's physical strength parameter (an example of a parameter that controls the progress of the game), a special attack that can significantly reduce the physical character of the opponent character compared to a normal attack The process of activating the character to the player character is performed. Further, for example, in the case of a racing game in which a moving body such as a car is moved on the course and competes for rank and time, a process of rapidly accelerating the moving body by adding a speed parameter of the moving body is performed. Note that these game processes are merely examples, and other aspects of game processes can be employed as appropriate. Note that parameters used in various games are stored in the storage unit 170.

  The determination unit 114 provides a value between each reference data value among a plurality of reference data stored in the reference data storage unit 174 within an input reception period in which an input according to a predetermined movement mode of the controller 16 is received. It is determined whether or not an output value that satisfies the above relationship is output from the sensor 162 in any of a plurality of predetermined orders. “Output value for which a given relationship is established with the reference data value” includes an output value that exceeds the reference data value, an output value that exceeds the reference data value, an output value that does not exceed the reference data value, or The output value falls below the reference data value. For example, in the case of a music performance game, it is stored in the reference data storage unit 174 within a period (an example of an input reception period) in which an instruction mark for instructing the player 20 to move the controller 16 in a predetermined movement mode is displayed. Output value that establishes a given relationship with each reference data value among a plurality of reference data (specifically, the reference data value when the reference data value is a positive integer) If the above output value or reference data value is a negative integer, it is determined whether or not the output value from the sensor 162 is output in any one of a plurality of orders. . In this embodiment, since the determination unit 114 performs the determination process for each frame, the determination process is performed using a plurality of output values. Further, “a plurality of predetermined orders” may be set in the program, or data for order determination may be prepared in the storage unit 170.

  The determination unit 116 determines a plurality of reference data stored in the reference data storage unit 174 based on the output value of the sensor 162 when the controller 16 moves in a predetermined movement mode. For example, before starting the game, the controller 16 is moved by the player in the movement mode used in the game, and a plurality of reference data is determined based on the output value from the sensor 162 when the controller 16 is moved. The reference data is stored in the reference data storage unit 174.

  The drawing unit 140 performs drawing processing based on the result of game processing or the like performed by the processing unit 100, thereby generating an image and outputting the image to the display unit 190. The image generated by the drawing unit 140 may be a so-called two-dimensional image or a three-dimensional image.

  When generating a two-dimensional image, drawing data is created by synthesizing objects so that an object with a high priority is displayed in front of an object with a low priority. Based on the drawing data, the combined object is drawn in a drawing buffer 176 (a buffer that can store image information in units of pixels such as a frame buffer or an intermediate buffer; VRAM) to generate a two-dimensional image.

  When generating a three-dimensional image, first, geometric processing such as coordinate transformation (world coordinate transformation, camera coordinate transformation), clipping processing, or perspective transformation is performed, and based on the processing result, drawing data (primitive vertices) Position coordinates, texture coordinates, color data, normal vector, α value, etc.). Then, based on this drawing data (primitive data), the object (one or a plurality of primitives) after perspective transformation (after geometry processing) is drawn in the drawing buffer 176. Thereby, an image that can be seen from the virtual camera (given viewpoint) in the game space is generated.

  Note that the game system 1 of the present embodiment may be a system dedicated to the single player mode in which only one player can play, or may be a system having a multiplayer mode in which a plurality of players can play. Further, when a plurality of players play, game images and game sounds to be provided to the plurality of players may be generated using a server or one game system 1, or a server connected via a network. Alternatively, it may be generated by distributed processing using a plurality of game systems 1.

3. Next, a method for controlling a music performance game performed in the game system 1 according to the present embodiment will be described with reference to FIGS.

3-1. Outline of Music Playing Game First, an outline of the music playing game of the present embodiment will be described with reference to FIGS. FIG. 3 is a diagram illustrating an example of a game image of the music performance game according to the present embodiment, and FIG. 4 is a diagram illustrating an example of a controller coordinate system.

  In the music performance game of the present embodiment, an instruction indicator for instructing the player 20 to move the controller 16 in a predetermined movement manner in accordance with the reproduction of the music is displayed on the display 19. The dance is choreographed by moving the controller 16 in the instructed movement mode.

  For example, in the example shown in FIG. 3, together with the player character 300, the controller 16 is instructed to move the controller 16 along a circular movement trajectory counterclockwise around the z-axis direction while the gravity G is acting in the −y-axis direction of the controller 16. An instruction mark 310 is displayed on the display 19. In the present embodiment, as shown in FIG. 4, the coordinate system of the controller 16 (acceleration sensor 30) is such that the horizontal direction of the controller 16 is the x axis, the vertical direction of the controller 16 is the y axis, and the front and rear direction of the controller 16 (longitudinal direction). ) Is defined as the z-axis, and it is assumed that the controller 16 is moved with reference to a state in which the gravity G acts in the −y-axis direction of the controller 16.

  Then, when the player 20 moves the controller 16 in the movement mode indicated by the indication sign 310, the player character 300 rotates the left arm 305 in the direction indicated by the indication sign 310 in accordance with the movement of the controller 16. The dance corresponding to the operation of the player 20 is reproduced.

  In addition, when the controller 16 is moved in accordance with the movement mode indicated by the instruction sign 310 while the instruction sign 310 is displayed on the display 19, the operation of the player 20 such as “GREAT!” Is increased. The display to evaluate is performed and the score is added. On the other hand, when the movement of the controller 16 according to the movement mode instructed by the instruction sign 310 is not performed while the instruction sign 310 is displayed on the display 19, the operation of the player 20 such as “BAD!” Is performed. A cruel display is made and no score is added.

  As described above, in this embodiment, when the player 20 moves the controller 16 in the movement mode instructed by the instruction sign, virtual reality as if the player 20 was acting as a dancer and choreographed a dance was obtained. You can enjoy an enhanced game.

3-2. Input Determination Method Next, the input determination method of this embodiment will be described with reference to FIGS.

  In the music performance game of the present embodiment, the movement start position and the movement end position are not specified in the instruction sign in order to allow a wide movement mode of the controller 16 (see FIG. 3). By the way, if the movement start position or movement end position when the controller 16 is moved is different, the output value (acceleration vector) output from the acceleration sensor 30 when the controller 16 is moved is completely different. This point will be described with reference to FIG. FIG. 5 is a diagram for explaining the difference in the output value of the acceleration sensor 30 due to the difference in the movement start position of the controller 16.

  When the controller 16 is moved counterclockwise about the z-axis direction with gravity G acting in the -y-axis direction, the controller 16 is moved in the -x-axis direction at the point 312. At this time, since the inertial force in the + x-axis direction acts on the acceleration sensor 30 (controller 16), the acceleration sensor 30 outputs a + output value in the x component. Further, since the gravity G in the −y-axis direction also acts on the acceleration sensor 30, an output value of − is also output for the y component.

  Further, at the position of the point 314, the controller 16 is moved in the -y axis direction. At this time, since the gravity G in the −y axis direction acts on the acceleration sensor 30 together with the inertia force in the + y axis direction, the acceleration sensor 30 outputs a positive output value in the y component or an output value of the y component when the controller 16 is stationary. Outputs an output value of − which is smaller in absolute value than.

  Further, at the position of the point 316, the controller 16 is moved in the + x axis direction. At this time, since the inertial force in the −x-axis direction acts on the acceleration sensor 30, the acceleration sensor 30 outputs an output value of − in the x component. Further, since the gravity G in the −y-axis direction also acts on the acceleration sensor 30, an output value of − is also output for the y component.

  Further, at the position of the point 318, the controller 16 is moved in the + y-axis direction. At this time, since the gravity G in the −y-axis direction acts on the acceleration sensor 30 together with the inertia force in the −y-axis direction, the acceleration sensor 30 has an absolute value in the y component that is larger than the output value of the y component when the controller 16 is stationary. Outputs a large negative output value.

  Thus, since the output value of the acceleration sensor 30 varies depending on the movement position (movement direction) of the controller 16, if the movement start position and movement end position when the controller 16 is moved are different, the controller The output value output from the acceleration sensor 30 between the start of the movement of 16 and the end of the movement is also completely different. If determination data corresponding to the movement start position and movement end position of the controller 16 is prepared so that the movement of the controller 16 can be dealt with from any position, the amount of data becomes enormous and the determination processing is performed. It becomes complicated.

  Therefore, in the present embodiment, a plurality of reference data associated with a predetermined movement mode of the controller 16 is stored in the reference data storage unit 174, and given to each reference data value in the plurality of reference data. Output value that satisfies the relationship (specifically, if the reference data value is a positive integer, the output value is greater than or equal to the reference data value, and if the reference data value is a negative integer, (Output value less than or equal to the value) is output from the acceleration sensor 30 in any one of a plurality of predetermined orders, and it is determined that the controller 16 has input according to a predetermined movement mode Is adopted. Hereinafter, this will be specifically described with reference to FIGS. FIG. 6 is a diagram illustrating an example of reference data used when the input determination of the movement mode indicated by the instruction mark 310 is performed. FIG. 7 illustrates the movement of the controller 16 specified by the reference data in FIG. FIG. 8 is a diagram illustrating the order in which the reference data in FIG. 6 is satisfied.

  In the present embodiment, using the reference data A to reference data H shown in FIG. 6, it is determined whether or not the controller 16 has been moved according to the movement mode indicated by the indication mark 310. Since gravity G does not work in the x-axis direction, the value of the x component of reference data A to reference data H is symmetric with respect to the y-axis, but gravity G works in the y-axis direction. The value of the y component of the reference data A to reference data H is not symmetric with respect to the x axis.

  In the reference data A, the value of the x component is set to 1.0, and the values of the y component and the z component are set to 0.0. That is, the reference data A is data for determining whether or not the controller 16 has been moved in the direction of the arrow 321 shown in FIG. 7 (if the controller 16 is moved in the direction of the arrow 321 (−x axis direction), the arrow 321 Inertial force works in the + x axis direction, which is the opposite direction of the acceleration sensor 30. As a result, the acceleration sensor 30 outputs an output value of + in the x component), and the acceleration sensor 30 outputs an output value of 1.0 or more in the x component. If it is determined, it is determined that the reference data A is satisfied.

If it is determined, it is determined that the reference data B is satisfied.

  In the reference data C, the y component value is set to 1.0, and the x component and z component values are set to 0.0.

It is determined that the reference data C is satisfied.

  In the reference data D, the value of the x component is set to -0.5, the value of the y component is set to 0.5, and the value of the z component is set to 0.0. That is, the reference data D is data for determining whether or not the controller 16 has been moved in the direction of the arrow 324 shown in FIG. 7, and an output value of −0.5 or less is output from the acceleration sensor 30 in the x component. At the same time, it is determined that the reference data D is satisfied when an output value of 0.5 or more is output in the y component.

  In the reference data E, the value of the x component is set to -1.0, and the values of the y component and the z component are set to 0.0. That is, the reference data E is data for determining whether or not the controller 16 is moved in the direction of the arrow 325 shown in FIG. 7, and an output value of −1.0 or less is output from the acceleration sensor 30 in the x component. It is determined that the reference data E is satisfied.

  In the reference data F, the value of the x component is set to -0.5, the value of the y component is set to -0.3, and the value of the z component is set to 0.0. That is, the reference data F is data for determining whether or not the controller 16 has been moved in the direction of the arrow 326 shown in FIG. 7, and an output value of −0.5 or less is output from the acceleration sensor 30 in the x component. At the same time, it is determined that the reference data F is satisfied when an output value of −0.3 or less is output for the y component.

  In the reference data G, the y component value of the acceleration vector is set to -0.5, and the x component and z component values are set to 0.0.

It is determined that the reference data G is satisfied.

  In the reference data H, the value of the x component of the acceleration vector is set to 0.5, the value of the y component is set to -0.3, and the value of the z component is set to 0.0. That is, the reference data H is data for determining whether or not the controller 16 has been moved in the direction of the arrow 328 shown in FIG. 7, and an output value of 0.5 or more is output from the acceleration sensor 30 in the x component. At the same time, it is determined that the reference data H is satisfied when an output value of −0.3 or less is output for the y component.

  Then, when the reference data A to the reference data H are satisfied in any order shown in FIG. 8, the controller 16 sets the z-axis direction in a state where gravity G acts in the −y-axis direction, as is apparent from FIG. Since the axis has been moved in a counterclockwise direction along a circular movement trajectory, it is determined that the controller 16 has been moved according to the movement mode indicated by the indication mark 310.

  As described above, in this embodiment, whether or not the controller 16 has been moved according to the movement mode indicated by the instruction mark 310 is determined based on the reference data A to the reference data H stored in the reference data storage unit 174. Therefore, the controller 16 according to the movement mode indicated by the indication mark 310 is used regardless of the movement start position of the controller 16. Can be recognized.

  It is stored in the reference data storage unit 174 based on the output value of the acceleration sensor 30 when the controller 16 is moved counterclockwise around the z-axis direction with gravity G acting in the -y-axis direction. The reference data A to the reference data H may be determined. In this case, before the game is started, the controller 16 is moved counterclockwise about the z-axis direction with the gravity G acting on the player 20 in the −y-axis direction, and the acceleration sensor 30 is moved when the controller 16 is moved. The reference data A to reference data H stored in the reference data storage unit 174 may be determined from the output value. For example, in the case of the reference data A, the x component having the largest value among the output values of the acceleration sensor 30 when the controller 16 is moved may be employed. In order to easily satisfy the value of the reference data, a value obtained by adjusting the output value of the adopted speed sensor 30 (a value obtained by increasing or reducing the output value of the adopted speed sensor 30) is used as reference data. Also good. In this way, it is possible to set the reference data A to reference data H suitable for the movement of the controller 16 by the player 20.

  Until now, as shown in FIG. 4, the description has been made on the assumption that the controller 16 is moved on the basis of the state in which the gravity G acts in the −y-axis direction. Subsequently, as shown in FIG. A case where the controller 16 is moved with reference to a state where gravity G acts in the −z axis direction of 16 will be described with reference to FIGS. 9 to 14. FIG. 9 is a diagram illustrating an example of a controller coordinate system, FIG. 10 is a diagram illustrating an example of a game image of the music performance game of the present embodiment, and FIG. 11 is a movement mode instructed by an instruction sign 340. FIG. 12 is a diagram illustrating an example of reference data used when performing the input determination of FIG. 11, FIG. 12 is a diagram illustrating an order satisfying the reference data of FIG. 11, and FIG. 13 is specified by the reference data of FIG. FIG. 14 is a diagram illustrating an example of the orientation of the controller 16 that is allowed when the controller 16 is moved in the movement mode indicated by the indication sign 340. .

  For example, in the example shown in FIG. 10, the player character 300 and the controller 16 are instructed to move the controller 16 along a circular movement trajectory counterclockwise around the z-axis direction while the gravity G is acting in the −z-axis direction of the controller 16. An instruction mark 340 to be displayed is displayed on the display 19.

  Then, using the reference data A ′ to reference data H ′ shown in FIG. 11, it is determined whether or not the controller 16 has been moved in accordance with the movement mode indicated by the indication mark 340. When the reference data A ′ to the reference data H ′ are satisfied in this order, the controller 16 rotates counterclockwise about the z-axis direction with gravity G acting in the −z-axis direction, as is apparent from FIG. Therefore, it is determined that the movement of the controller 16 according to the movement mode indicated by the indication mark 340 has been performed.

  Although detailed description is omitted, the reference data A ′ is data for determining whether or not the controller 16 is moved in the direction of the arrow 351 shown in FIG. 13, and the reference data B ′ is the arrow shown in FIG. The reference data C ′ is data for determining whether or not the controller 16 has been moved in the direction of the arrow 353 shown in FIG. The data D ′ is data for determining whether or not the controller 16 is moved in the direction of the arrow 354 shown in FIG. 13, and the reference data E ′ is that the controller 16 is moved in the direction of the arrow 355 shown in FIG. The reference data F ′ is data for determining whether or not the controller 16 has been moved in the direction of the arrow 356 shown in FIG. The data G ′ is data for determining whether or not the controller 16 has been moved in the direction of the arrow 357 shown in FIG. 13, and the reference data H ′ is the data on which the controller 16 has been moved in the direction of the arrow 358 shown in FIG. This is data for determining whether or not.

  Then, the controller 16 is moved along the arrow in the direction of the controller 16 shown in FIG. 14A (with a circular movement trajectory counterclockwise around the z-axis direction with gravity G acting in the −z-axis direction). In this case, the reference data is satisfied in the order of A ′ → B ′ → C ′ → D ′ → E ′ → F ′ → G ′ → H ′.

  By the way, when the gravity G acts in the −z-axis direction, the gravity G does not act in the x-axis direction and the y-axis direction, so the coordinates of the reference data A ′ to the reference data H ′ are centered on the z-axis. When it rotates, it becomes rotationally symmetric at 90, 180, 270, and 360 degrees. That is, the coordinates of the reference data A ′ to the reference data H ′ are four-fold rotationally symmetric. “Rotational symmetry” means that the movement trajectory (coordinates) is the same before and after rotation when the movement trajectory (coordinates) is rotated around the axis. When the movement locus (coordinates) is rotated in the range of 0 to 360 degrees around the axis, the movement locus (coordinates) coincides four times.

  Further, the movement trajectory (coordinates) of the circle is the same before and after the rotation even when the circle is rotated at any angle from 0 degrees to 360 degrees around the axis.

  Accordingly, when the controller 16 is moved in the movement mode indicated by the instruction mark 340, if the gravity G works in the −z-axis direction, not only the movement start position of the controller 16 but also the inclination ( The movement mode of the controller 16 can be properly recognized regardless of the orientation.

  For example, in the state rotated from 0 to 45 degrees counterclockwise from the direction of the controller 16 shown in FIG. 14A with the z-axis direction as an axis (FIG. 14B shows a state rotated by 45 degrees). When the controller 16 is moved along the arrow, the reference data is satisfied in the order of H ′ → A ′ → B ′ → C ′ → D ′ → E ′ → F ′ → G ′.

  14A is rotated 45 degrees to 90 degrees counterclockwise about the z-axis direction from the direction of the controller 16 shown in FIG. 14A (shown in FIG. 14C showing a state rotated 90 degrees). When the controller 16 is moved along the arrow, the reference data is satisfied in the order of G ′ → H ′ → A ′ → B ′ → C ′ → D ′ → E ′ → F ′.

  14A is rotated 90 degrees to 135 degrees counterclockwise about the z-axis direction from the direction of the controller 16 shown in FIG. 14A (FIG. 14D shows a state rotated 135 degrees). When the controller 16 is moved along the arrow, the reference data is satisfied in the order of F ′ → G ′ → H ′ → A ′ → B ′ → C ′ → D ′ → E ′.

  14A is rotated 135 degrees to 180 degrees counterclockwise around the z-axis direction from the direction of the controller 16 shown in FIG. 14A (FIG. 14E shows a state rotated 180 degrees). When the controller 16 is moved along the arrow, the reference data is satisfied in the order of E ′ → F ′ → G ′ → H ′ → A ′ → B ′ → C ′ → D ′.

  14A is rotated 180 degrees to 225 degrees counterclockwise around the z-axis direction from the direction of the controller 16 shown in FIG. 14A (FIG. 14F shows a state rotated 225 degrees). When the controller 16 is moved along the arrow, the reference data is satisfied in the order of D ′ → E ′ → F ′ → G ′ → H ′ → A ′ → B ′ → C ′.

  14A is rotated 225 to 270 degrees counterclockwise about the z-axis direction from the direction of the controller 16 shown in FIG. 14A (shown in FIG. 14G shows a state rotated 270 degrees). When the controller 16 is moved along the arrow, the reference data is satisfied in the order of C ′ → D ′ → E ′ → F ′ → G ′ → H ′ → A ′ → B ′.

  14A is rotated 270 to 315 degrees counterclockwise about the z-axis direction from the direction of the controller 16 shown in FIG. 14A (FIG. 14H shows a state rotated 315 degrees). When the controller 16 is moved along the arrow, the reference data is satisfied in the order of B ′ → C ′ → D ′ → E ′ → F ′ → G ′ → H ′ → A ′.

  In addition, when the controller 16 is moved along the arrow in a state of being rotated 315 to 360 degrees counterclockwise from the direction of the controller 16 shown in FIG. The reference data is satisfied in the order of B ′ → C ′ → D ′ → E ′ → F ′ → G ′ → H ′.

  In the present embodiment, a circle whose movement trajectory is the same before and after rotation is adopted even when the axis is rotated at any angle of 0 to 360 degrees around the axis. You may employ | adopt the square which is a rotationally symmetrical movement locus | trajectory as a movement locus | trajectory. In this case, if the coordinates of the plurality of reference data associated with the square movement locus are rotationally symmetric four times, the controller 16 is rotated 90 degrees, 180 degrees, 270 degrees, 360 degrees, Even if the controller 16 is moved along a square movement locus, the movement mode of the controller 16 can be appropriately recognized.

3-3. Processing of this Embodiment Next, an example of processing of this embodiment will be described with reference to FIG. FIG. 15 is a flowchart for explaining an example of processing according to the present embodiment.

  When a game stage to be played by the player is selected from among a plurality of game stages, the game system 1 starts playing a music performance game by playing music according to the selected game stage (step S10).

  Subsequently, an indication indicator for instructing the player 20 to move the controller 16 in a predetermined movement mode is displayed on the display 19 (Y in step S12), and while the indication indicator is displayed, a plurality of reference data items are displayed. It is determined whether or not an output value that establishes a given relationship with each reference data is output from the acceleration sensor 30 in any of a plurality of predetermined orders (step S14). If it is determined that it has been output (Y in step S14), the score is added (step S16).

  Then, the process of step S12 to step S16 is repeated until the reproduction of the music is completed (N in step S18), and when the reproduction of the music is completed, the music performance game is terminated (Y in step S18).

4). Modifications The present invention is not limited to that described in the above embodiment, and various modifications can be made. In addition, the configuration described in the above embodiment is merely an example, and even when an equivalent technique that achieves the same effect as the configuration of the above embodiment is employed, it can be included in the scope of the present invention.

  For example, in the above-described embodiment, the input determination method has been described by taking the movement trajectory of a circle, which is a movement mode extending over two axes (x axis and y axis), as an example, but a movement mode extending over three axes or one axis (x axis, This input determination method can also be applied to movement on the y-axis or the Z-axis). For example, when the controller 16 is swung left and right (x-axis direction) with gravity G acting in the -y-axis direction, the reference data A and the reference data E in FIG. Alternatively, if the reference data is satisfied in the order of E → A, it can be determined that the controller 16 is swung left and right.

  In the above embodiment, the controller 16 is moved counterclockwise about the z-axis direction as an example. However, the controller 16 may be moved clockwise about the z-axis direction. This case can be dealt with by reversing the order shown in FIGS. For example, in the order of A → B → C → D → E → F → G → H shown in FIG. 8, H → G → F → E → D → C → B → A may be used. Further, both the clockwise direction and the counterclockwise direction may be supported without specifying the direction in which the controller 16 is moved.

  Further, in the above-described embodiment, the player 20 is notified that the controller 16 is moved in a predetermined movement mode by displaying an instruction sign on the display 19. However, an instruction sound is output from a speaker, and the brightness of the display 19 is displayed. May be notified to the player 20 that the controller 16 is moved in a predetermined movement mode by increasing the brightness of the screen. Further, the controller 16 may be provided with a built-in vibrator and may be notified by vibrating the vibrator, or the controller 16 may be provided with a speaker and the instruction sound may be output from the speaker. Further, for example, in a fighting game, when the controller 16 is moved in a predetermined movement mode, a special attack is activated on the player character, or in a racing game, the moving body is accelerated rapidly when the controller 16 is moved in a predetermined movement mode. In this case, it is not necessary to notify the player 20 that the controller 16 is moved in a predetermined movement mode.

  Moreover, in the said embodiment, although the period when the indication mark was displayed on the display 19 was demonstrated as the input reception period, for example, after the indication sign is displayed, the indication mark is further lit to indicate the period during which the indication sign is lit. It is good.

  In addition, the processing of each unit (each unit) in the above embodiment may be realized entirely by hardware, or may be realized by a program stored in an information storage medium or a program distributed via a communication interface. May be. Alternatively, it may be realized by both hardware and a program. When the processing of each unit of this embodiment is realized by both hardware and a program, a program for causing the hardware (computer) to function as each unit of this embodiment is stored in the information storage medium. .
