Description

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

  2. Description of the Related Art Conventionally, a game system is known in which a player plays a music game by operating a controller (an example of an operation unit) that simulates a musical instrument. In this game system, music is output from a sound output unit (for example, a speaker), and a mark (musical note for instructing the timing and type of input operation of the player is displayed on a display unit (for example, a CRT or a liquid crystal display). ) Is displayed. While listening to the output music, the player operates the controller according to the displayed mark and enjoys the music game.

However, in the conventional game system, the player's operation result is determined only by turning on / off the switch, and it is impossible to determine the strength of the operation. Further, if the controller switch itself is configured to allow analog input, it is difficult to set the sensitivity of the sensor, and the cost of the controller parts becomes high.

  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 capable of improving the input interface environment of a music game.

  (1) The present invention is a game system for a music game that is played by a player operating an operation unit, the music playback unit playing back music data stored in a storage unit, and the player operating the operation unit A display control unit for performing display control for displaying an operation instruction mark for instructing an operation to be performed in conjunction with a reproduction state of the music data, and a player during the determination period set for the operation instruction mark When the operation is performed, an acquisition unit that acquires the operation timing of the operation unit of the player, the detected sound volume of the operation sound detected by the sound detection unit during the determination period, and the acquired operation An operation timing determination process for comparing the timing with a reference timing and a volume determination process for comparing the acquired detected volume with a reference volume are performed. An evaluation unit that evaluates a player's operation based on each determination result of the determination process and the volume determination process, and the evaluation unit operates the operation unit of the player based on the determination result of the volume determination process. Relevant to game systems that assess strength. The present invention also relates to a program that causes a computer to function as each of the above-described units. The present invention also relates to an information storage medium that can be read by a computer, and stores (records) a program that causes the computer to function as each of the above-described units.

  In this specification, the operation sound means that the player performs a striking operation (striking operation) on the striking surface of the operation unit, vibrates the string of the operation unit, or presses a button. Means the sound that occurs. In the present specification, the expression “volume” means the amplitude value of a sound wave in a broad sense, and includes what is called sound pressure.

  In the present invention, a sound detection process is performed for causing the sound detection unit to detect a sound generated when the player operates the operation unit, and determining the operation intensity of the operation unit of the player based on the detected sound volume.

If the sound is generated by the sound input operation of the player based on the determination result of the sound volume determination process is evaluated as satisfying the sound volume condition indicated by the sound input instruction mark, the detection The sound input operation of the player may be evaluated based on the determination result of the timing determination process.

  In this way, it is possible to inform the player in an easy-to-understand manner what type of sound input operation should be performed for the sound input instruction mark displayed on the game screen. In this way, it is possible to give the player a strong motivation to perform a sound input operation so as to satisfy a predetermined volume condition.

  (6) In the game system of the present invention, the evaluation unit performs an input type determination process based on the operation timing of the operation unit and the detection timing of the sound detection unit acquired by the acquisition unit, and the input type In the determination process, when it is determined that the operation timing of the operation unit and the detection timing of the sound detection unit are acquired in the determination period set for the operation instruction mark, the operation timing is Based on the operation timing determination process, the operation timing of the operation unit and the detection timing of the sound detection unit are overlapped and acquired within the determination period set for the sound input instruction mark in the input type determination process. If it is determined that the detection has been performed, the detection timing determination process based on the detection timing may not be performed.

  In this way, in a system in which an input operation (operation or sound input operation) is performed by a player using input interfaces having different input types, that is, an operation unit and a sound detection unit, the operation of the operation unit and the sound detection unit Sound input operation can be accurately determined. That is, it is possible to prevent erroneous evaluation due to erroneous input.

  (7) In the game system, the program, and the information storage medium of the present invention, the acquisition unit stores waveform information of the operation sound of the operation unit detected by the sound detection unit during the determination period set for the operation instruction mark. The evaluation unit may perform a waveform determination process that compares the acquired waveform information with a reference waveform, and may evaluate a player's operation based on a result of the waveform determination process.

  The waveform information of the operation sound is not limited to the shape of the waveform itself, but in a broad sense means information including the frequency, wavelength, phase, and the like of the operation sound. In this way, the input operation of the player can be evaluated based on evaluation indexes such as timbre and pitch.

  (8) The present invention is also a game system for a game that is played by a player operating an operation unit, and when the player operates the operation unit during a given determination period, An operation unit that acquires operation data of the operation unit, detection sound data of the operation sound of the operation unit detected by the sound detection unit during the determination period, and an operation for comparing the acquired operation data and reference operation data Evaluation that performs a determination process and a sound determination process that compares the acquired detection sound data and reference sound data, and evaluates the player's operation based on the determination results of the operation determination process and the sound determination process And a game system including The present invention also relates to a program that causes a computer to function as each of the above-described units. The present invention also relates to an information storage medium that can be read by a computer, and stores (records) a program that causes the computer to function as each of the above-described units.

In FIG. 1, the case of a home game device is shown as an example, but the present invention can also be applied to a commercial game device.

  FIG. 2 shows an example of a functional block diagram of the game system (image generation system) of the present embodiment. Note that the game system of the present embodiment does not have to include all the components (each unit) in FIG. 2, and may have a configuration in which some of them are omitted. Further, the music game realized by the game system (program) of the present embodiment is a game for playing music with an input unit imitating a musical instrument, a game for dancing according to music, or the like. These games are sometimes called rhythm action games.

  The input device 160 is for a player to input operation data and sound data, and functions thereof are a controller imitating a percussion instrument as shown in FIG. 1, an operation button, an operation lever, a touch panel, a voice input microphone, or the like. It can be realized by hardware. The storage unit 170 is a work area such as the processing unit 100 or the communication unit 194, and its function can be realized by hardware such as a RAM.

  The information storage medium 180 (computer-readable medium) stores programs, data, and the like, and functions as an optical disk (CD, DVD), magneto-optical disk (MO), magnetic disk, hard disk, and magnetic tape. Alternatively, it can be realized by hardware such as a memory (ROM). The processing unit 100 performs various processes of this embodiment based on a program (data) stored in the information storage medium 180. That is, the information storage medium 180 stores a program for causing a computer to function as each unit of the present embodiment (a program for causing a computer to execute processing of each unit). The portable information storage device 182 stores player personal data, game save data, and the like, and examples of the portable information storage device 182 include a memory card and a portable game device.

  The display unit 190 outputs an image generated according to the present embodiment, and its function can be realized by hardware such as a CRT, LCD, touch panel display, or HMD (head mounted display). The sound output unit 192 outputs the sound generated by the present embodiment, and its function can be realized by hardware such as a speaker or headphones. The communication unit 194 performs various controls for communicating with the outside (for example, a host device or other game system), and functions thereof include hardware such as various processors or communication ASICs, It can be realized by software such as programs.

  Note that a program (data) for causing a computer to function as each unit of the present embodiment is distributed from the information storage medium of the host device (server) to the information storage medium 180 (storage unit 170) via the network and communication unit 194. You may do it. Use of the information storage medium of such a host device (server) can also be included in 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 input data from the input device 160, a program, and the like. Here, the game process performed by the processing unit 100 includes a process for starting a game when a game start condition is satisfied, a process for advancing the game, a process for arranging display objects (objects) such as various marks and characters, and a display. There are a process for displaying an object, a process for calculating a game result, a process for ending a game when a game end condition is satisfied, and the like. The processing unit 100 performs various processes using the storage unit 170 as a work area. The function of the processing unit 100 can be realized by hardware such as various processors (CPU, DSP, etc.), ASIC (gate array, etc.), and a program (game program).

  The processing unit 100 includes a display control unit 111, an acquisition unit 112, an input determination unit 113, an evaluation unit 114, an image generation unit 120, and a sound generation unit 130. Note that some of these may be omitted.

  The display control unit 111 performs display control of a plurality of display objects including instruction marks (musical notes) and reference marks. Specifically, a process of arranging a display object, a process of moving the display object, or a process of changing the display mode of the display object is performed.

  Here, the instruction mark is a mark for instructing an input operation to be performed by the player to the operation input unit 162 or the sound input unit 164 of the input unit 160, and the image data is stored in the mark storage unit 172 of the storage unit 170. Remembered. As the instruction mark, an operation instruction mark (first instruction mark in a broad sense) for instructing a hit operation of the operation unit 162 and a sound input instruction mark (in a broad sense, for instructing applause to be performed to the sound detection unit 164). Second instruction mark). In this case, it is preferable to display the operation instruction mark and the sound input instruction mark in different display modes (color, shape, pattern, etc.). When the operation unit 162 has a plurality of operation areas, an operation instruction mark having a display mode corresponding to each operation area can be displayed. In this way, the player can identify the hitting operation to be performed in a plurality of different operation areas by the difference in the display mode of each instruction mark.

  The reference mark is a mark that indicates to the player part or all of the determination period set for the instruction mark mainly based on the positional relationship with the instruction mark. The image data is stored in the mark storage section of the storage section 170. 172 stored. The reference mark is also a mark indicating to the player the reference timing for evaluating the timing (operation timing or detection timing) of the player's input operation performed in response to the instruction mark.

  Then, the display control unit 112 changes the positional relationship between the instruction mark and the reference mark, and performs display control for bringing both marks closer. This allows the player to recognize the determination period set for the displayed instruction mark. In the multiplayer mode, display control for changing the positional relationship between each instruction mark and each reference mark is performed by displaying a dedicated instruction mark and reference mark on each player.

  Here, changing the positional relationship to bring the marks closer to each other is not only when one mark is stationary and the other mark moves to move closer, but each mark moves to move the marks to each other. Including the case where the position of

  Further, the display control unit 111 instructs the player on the operation intensity condition of the tapping operation that the player should perform on the operation unit 162 and the sound volume condition that the player should generate by applause by the operation instruction mark and the sound input instruction mark. Perform display control. In this way, the contents of the input operation to be performed by the player can be notified in an easy-to-understand manner. Specifically, depending on the display mode (color, shape, pattern, size, etc.) of the operation instruction mark and sound input instruction mark, the operation strength condition of the tapping operation and the sound volume condition of the sound generated by the applause are specified. can do.

  The acquisition unit 112 responds to the instruction mark (operation instruction mark or sound input instruction mark) when the player performs an input operation (percussion instrument performance or clapping) on the input device 160 in the determination period set for each instruction mark. In addition, processing for obtaining various input data for evaluating the input operation is performed. Specifically, input data from the input device 160 is monitored and acquired for each frame. The acquired input data is stored in a given storage buffer. A frame (for example, 1/60 seconds, 1/30 seconds) is a unit of time for performing game processing (movement / motion processing of display objects) and image generation processing.

  That is, the acquisition unit 112 acquires the operation timing (operation data in a broad sense) when the player strikes the operation unit 162, and the sound detection unit 164 when the player performs applause. A process of acquiring the detection timing of the detected applause sound is performed.

  In addition, when the player operates the operation unit 162 during the determination period set for the operation instruction mark, the acquisition unit 112 detects the hit operation sound of the operation unit 162 detected by the sound detection unit 164 during the operation instruction mark determination period. A process of acquiring detected sound volume or waveform information (detected sound data in a broad sense) as data for evaluating a player's hitting operation is performed. Note that the detected sound volume may be the sound volume detected by the sound detection unit 164 at the operation timing of the operation unit 162 of the player, or the sound detection unit 164 within a given delay time from the operation timing. It may be the maximum value (maximum volume) of the volume of the detected sound. In particular, when the operation unit 162 and the sound detection unit 164 are separated from each other, since the operation sound is detected with a delay from the operation timing of the operation unit 162, the maximum volume of the sound detected within the delay time is detected. It is preferable to acquire the value as the detected sound volume. In this case, the delay time can be set based on the positional relationship between the operation unit 162 and the sound detection unit 164.

  In addition, when the player claps during the determination period set for the sound input instruction mark, the acquisition unit 112 determines the detected sound volume of the applause detected by the sound detection unit 164 during the sound input instruction mark determination period. A process of obtaining data for evaluating the applause (sound input operation) of the player is performed. Note that the detected sound volume generated by the applause of the player is preferably the detected sound volume at the detection timing used in the timing determination process described later.

  The evaluation unit 114 includes an input type determination unit 115, a sound determination unit 116, and a timing determination unit 117, and performs a process of evaluating a player's input operation (striking operation or applause) based on the processing result of each determination unit.

  The input type determination unit 115 performs input type determination processing based on the operation timing of the operation unit 162 acquired by the acquisition unit 112 and the detection timing of the sound detection unit 164. Specifically, when it is determined that the operation timing of the operation unit 162 and the detection timing of the sound detection unit 164 are acquired in the determination period set for the operation instruction mark, the acquired operation is performed. It is determined that the timing is based on an appropriate input operation. That is, the acquired operation timing is processed as input data to be used for the timing determination process. Further, when it is determined that the operation timing of the operation unit 162 and the detection timing of the sound detection unit 164 are acquired in the determination period set for the sound input instruction mark, the detection of the sound detection unit 164 is performed. A process for determining that the timing is based on an erroneous input is performed. In other cases, a process of determining that the detection timing acquired during the determination period set for the sound input instruction mark is based on an appropriate input operation is performed. In other words, if the player makes an erroneous input to the operation unit 162 within the determination period for the sound input instruction mark, the detection timing should be used for the timing determination process even if the operation sound is detected by the sound detection unit 164. Process as input data that is not.

  The sound determination unit 116 performs a sound volume determination process (sound determination process in a broad sense) that compares the detected sound volume acquired by the acquisition unit 112 with a reference sound volume (reference sound data in a broad sense). Based on the result, the operation intensity of the operation unit 162 of the player and the loudness generated by the player's applause (sound input operation) are evaluated. Specifically, the reference volume data is stored in the reference data storage unit 174 of the storage unit 170. The reference volume can be set by a threshold value or a range. A plurality of thresholds and ranges for setting the reference volume may be set for one instruction mark. The sound determination unit 116 reads out the stored reference volume data, and the acquired detected volume exceeds the threshold set as the reference volume, or the acquired detected volume is within the range set as the reference volume. A process for determining whether the sound falls within the range is performed as a sound volume determination process. For example, when it is instructed to perform a strong input operation in the operation instruction mark or the sound input instruction mark, in the volume determination process, if the acquired detected volume exceeds the threshold set as the reference volume The hit operation (operation) of the player's operation unit 162 or the applause (sound input operation) of the player is evaluated as an appropriate input operation. On the other hand, if the detected sound volume acquired in this case is less than the threshold value set as the reference sound volume, it is evaluated that the player's operation of the operation unit 162 or the player's applause is an incorrect (inappropriate) input operation. Is done.

  Further, the sound determination unit 116 performs a waveform determination process (sound determination process in a broad sense) that compares the waveform information of the tapping operation sound of the operation unit 162 acquired by the acquisition unit 112 and the reference waveform, and the determination result Based on the above, a process of evaluating the hit operation of the operation unit 162 of the player is performed. Specifically, volume change (sound wave shape), frequency change, wavelength change or phase change with respect to the time axis of the reference tapping operation sound is stored in the reference data storage unit 174 of the storage unit 170 as reference waveform data. In addition, a process for comparing the reference waveform with the acquired waveform information of the hitting operation sound and determining the degree of coincidence or deviation is performed as the waveform determination process. For example, in the waveform determination process, the player's hitting operation is given higher evaluation as the acquired hitting operation sound waveform is determined to be closer to the reference waveform. In this way, the player's hitting operation can be evaluated based on evaluation indexes such as timbre and pitch.

  The timing determination unit 117 compares the operation timing or detection timing acquired by the acquisition unit 112 with a reference timing (reference operation data in a broad sense) (operation timing determination processing or detection timing determination processing, in a broad sense). The operation determination process is performed, and the player's input operation (striking operation or applause) is evaluated based on the determination result. Specifically, reference timing data serving as a model is stored in the reference data storage unit 174 of the storage unit 170. The timing determination unit 115 reads out the stored reference timing data, determines the degree of coincidence between the acquired operation timing or detection timing and the reference timing, and determines whether the operation timing or detection timing is different from the reference timing. A process for determining the degree is performed as a timing determination process. For example, in the timing determination process, the closer the acquired operation timing and detection timing are to the reference timing, the higher evaluation is given to the player's tapping operation and applause (input operation). Note that the timing determination process is based on the determination results of the input type determination process of the input type determination unit 115 and the sound volume determination process of the sound determination unit 116, and the appropriate input in which the input operation of the player matches the instruction content. You may make it perform based on the operation timing determined as operation | movement, and a detection timing. Also, based on the determination results of the input type determination process of the input type determination unit 115 or the volume determination process of the sound determination unit 116, the input operation (striking operation or applause) of the player is different from the instruction content (error) The operation timing and the detection timing determined to be the input operation may be processed with a determination result corresponding to the lowest evaluation in the timing determination process.

  In this embodiment, the display control unit 111 performs control to display the operation instruction mark and the sound input instruction mark in conjunction with the reproduction of the music data. When the player performs an input operation (hit operation or applause of the operation unit 162) during the determination period of the operation instruction mark or the sound input instruction mark, the evaluation unit 114 inputs the timing acquired for the input operation. The type is evaluated by the input type determination process of the input type determination unit 115 to evaluate whether or not the input operation is proper. In addition, the sound determination unit 116 performs a sound volume determination process for comparing the detected sound volume of the tapping operation sound or the applause sound detected by the sound detection unit 164 with respect to the input operation performed by the player and the reference sound volume, and based on the determination result. It is determined whether or not the strength of the player's tapping operation or the volume of applause is appropriate that satisfies the instructed condition. The timing determination unit 115 compares the operation timing acquired by the acquisition unit 112 or the detection timing with the reference timing with respect to the timing determined to be an appropriate input operation in the input type determination processing and the volume determination processing. Then, the player's hitting operation or applause is evaluated based on the determination result, and the player's score or the like is calculated as the evaluation result.

  Note that the operation instruction mark and the sound input instruction mark are displayed in conjunction with the reproduction of the music data, for example, when the reproduction of the music data (output of the music data) is started, each instruction mark and the reference mark are displayed. The movement display process for changing the positional relationship is started, and the movement display process is also terminated when the reproduction of the music data is completed. When the operation instruction mark or the sound input instruction mark is displayed in conjunction with the reproduction (reproduction status) of the music data, for example, the display timing of each instruction mark is associated with the sound reproduction timing of the music data. including.

  The image generation unit 120 performs drawing processing based on the results of various processes (game processing) performed by the processing unit 100, thereby generating an image and outputting the image to the display unit 190.

  The sound generation unit 130 performs sound processing based on the results of various processes performed by the processing unit 100, generates game sounds such as BGM, sound effects, or sounds, and outputs the game sounds to the sound output unit 192. The music reproducing unit 132 reproduces the music data of the music game realized in the game system of the present embodiment. Specifically, a process of reading out music data (music data in a broad sense) stored in the music data storage unit 178 of the storage unit 170, generating a game sound based on the music data, and outputting the game sound to the sound output unit 192 is performed. Do.

  Note that the game system of the present embodiment may be a system dedicated to the single player mode (single player format) that can be played by only one player, and not only such a single player mode but also a plurality of players can play. The system may also be provided with a multiplayer mode (multiplayer format). Further, when a plurality of players play, game images and game sounds to be provided to the plurality of players may be generated using one terminal, or connected via a network (transmission line, communication line) or the like. Alternatively, it may be generated using a plurality of terminals (game machine, mobile phone).

2. Next, the method of this embodiment will be described with reference to the drawings.

2.1 Method of operation instruction and sound input instruction In the present embodiment, display control for displaying operation instruction marks and sound input instruction marks having different display modes is performed, and the operation unit of the input device (percussion instrument type controller) 160 is operated. An instruction of a tapping operation (operation) 162 and an instruction of applause (sound input operation) to the sound detection unit 164 are performed.

  For example, in FIG. 3A, the display control is performed so that the operation instruction mark SDM and the sound input instruction mark ODM move toward the reference mark RM in conjunction with the reproduction of the music data on the line (score) MLN. Has been done. The operation instruction mark SDM and the sound input instruction mark ODM are displayed in a display form that allows the player to identify the instruction. For example, the shape, pattern, color, size, etc. can be different. The player observes the movement of the operation instruction mark SDM and the sound input instruction mark ODM through the game screen displayed on the display unit 190. As shown in FIG. 3B, for example, the operation instruction mark SDM is the reference mark RM. The operation unit 162 of the input device 160 is hit and operated in accordance with the timing of passing through. At this time, as shown in FIG. 3B, when a hit operation is performed at a timing (reference timing) at which the center portion of the operation instruction mark SDM overlaps the reference mark RM, a high evaluation (“GREAT”) is obtained. A high score reflecting the evaluation is given. The same applies to the sound input instruction mark ODM. When applause is performed at the timing when the center of the sound input instruction mark ODM overlaps the reference mark RM, a high evaluation is given, and a high score reflecting the evaluation is given.

  In FIGS. 3A and 3B, the operation instruction mark SDM and the sound input instruction mark ODM are moved and displayed, and the reference mark RM is displayed stationary. However, the operation instruction mark SDM and the sound input instruction mark ODM are stationary. The sound input instruction mark ODM may be displayed stationary and the reference mark RM may be moved and displayed. Alternatively, both the operation input instruction mark SDM, the sound input instruction mark ODM, and the reference mark RM may be moved closer to each other. That is, any display control may be used as long as the relative positional relationship between the reference mark RM for timing determination, the operation input instruction mark SDM, and the sound input instruction mark ODM is changed to bring them closer together. Further, when the game realized in this embodiment is played by a plurality of players, the operation input instruction mark SDM and the sound input instruction mark ODM are controlled to be displayed at the same display timing for all players. Alternatively, it may be controlled to display at a different display timing for each player.

  Further, in this embodiment, in order to evaluate the strength of the hitting operation (operation intensity) on the operation unit 162 of the player and the loudness of the applause sound of the player, the player is provided with the operation instruction mark and the sound input instruction mark. Display control is performed to change the display mode according to the strength of the input operation to be performed by the player.

  Specifically, as shown in FIG. 4, the operation instruction mark color is changed between strong input (strong hitting operation) and weak input (weak hitting operation) regarding the indication of the operation strength of the operation unit 162. Display control for changing the color of the sound input indication mark between strong input (applause of loud sound) and weak input (applause of small sound) regarding the indication of the magnitude of the generated applause sound to the sound detection unit 164 Do. The display mode of each indication mark may be different, for example, in shape, pattern, size, etc., in addition to different colors for a mark for instructing strong input and a mark for instructing weak input. it can.

  FIG. 5 shows a display example in which the display mode of the operation instruction mark and the sound input instruction mark is changed with respect to instructions of strong input and weak input. The operation instruction mark SDM1 indicates that a strong hitting operation should be performed, and the operation instruction mark SDM2 indicates that a weak hitting operation should be performed. The sound input instruction mark ODM1 indicates that a small sound should be input, and the sound input instruction mark ODM2 indicates that a large sound should be input. In response to these instruction marks, the player operates the operation unit 162 (striking operation) and performs a sound input operation (applause) while matching the timing while viewing the positional relationship between each instruction mark and the reference mark RM. The music game is played by hitting and applauding the operation unit 162 so as to satisfy the condition of the input strength indicated by each indication mark.

2.2 Notification Method of Instruction Mark Determination Period In this embodiment, the input to be performed by the player is performed by performing display control for changing the positional relationship between the reference mark and the instruction mark (operation instruction mark or sound input instruction mark). The player is informed of the determination period set for the instruction mark that instructs an action (a hit operation or applause of the operation unit 162).

  For example, in FIGS. 6A to 6C, the instruction mark DM is moved and displayed toward the reference mark RM that is stationary displayed at the reference position on the line MLN (a given position in a broad sense). . Then, the relative positional relationship between the reference mark RM and the instruction mark DM is changed, and display control is performed so that they are close to each other. In FIG. 6 (A), the player is informed that the start (one end in a broad sense) of the instruction mark DM has reached the reference mark RM and the determination period set for the instruction mark DM starts from that point. Yes. In FIG. 6B, the instruction mark DM is further moved, and the instruction mark DM and the reference mark RM are overlapped. This state means that the instruction mark DM is being determined. Then, when the instruction mark DM moves further and the last end (in the broad sense, the other end) of the instruction mark DM reaches the reference mark RM as shown in FIG. 6C, the instruction mark DM is set. It means that the judgment period ends. In other words, it means that even if the player performs an input operation (tapping operation or applause) beyond this point, it is not an object of evaluation, or a minimum evaluation is given. In this way, in the present embodiment, the determination period set for the indication mark DM can be shown to the player in an easy-to-understand manner based on the positional relationship with the reference mark RM displayed statically by the movement display processing of the indication mark DM.

  The indication mark DM may be displayed stationary, and the reference mark RM may be moved and displayed to move the marks closer. Further, the indication mark DM and the reference mark RM may be moved and displayed to move the marks closer. May be. In the example of FIGS. 6A to 6C, a case is described in which display control as shown to the player is performed for the entire determination period set for the instruction mark DM depending on the degree of overlap with the reference mark RM. However, the determination period of the instruction mark DM notified to the player based on the positional relationship between the instruction mark DM and the reference mark RM may be a part of the determination period.

  In addition, the manner in which the determination period set for the instruction mark DM is displayed is not limited to the above, and can be changed in various ways. For example, as shown in FIG. 7A, by displaying the reference mark RM in the same shape as the instruction mark DM, the period in which the reference mark RM and the instruction mark DM overlap is determined as the determination period of the instruction mark DM. It is good. Further, for example, as shown in FIG. 7B, a period in which the instruction mark DM and the reference mark RM overlap by changing the length of the instruction mark DM may be set as the determination period of the instruction mark DM. .

2.3 Evaluation Method of Player Input Action In this embodiment, the player's input action is evaluated by determining each of the input type, input strength, and input timing of the player's input action. Hereinafter, the determination methods will be described separately.

2.31 Input Type Determination Method for Player Input Operation Next, an input type evaluation method for the player input operation (hitting operation or applause) according to the present embodiment will be described. In the game system of the present embodiment, a music game is played using input interfaces with different input types, that is, an operation unit 162 and a sound detection unit 164. However, the sound detection unit 164 cannot distinguish and detect the sound generated by the hit operation of the operation unit 162 (hit operation sound) and the sound generated by the applause. A detection member that can distinguish these generated sounds is expensive, and application to a game system is not practical. Therefore, in the present embodiment, in order to appropriately evaluate the input operation performed by the player in response to the operation instruction mark or the sound input instruction mark, timing data (operation timing and detection) acquired for the input operation performed by the player. The input type determination method is used to accurately determine the input operation intended by the player by using the (timing) acquisition time.

  Specifically, as shown in FIG. 8A, the operation timing T1 is acquired and the operation unit 162 is obtained because the player accidentally hits the operation unit 162 in the determination period Th for the sound input instruction mark. Is detected at detection timing T2. In this case, when the input operation is evaluated based on the detection timing of the tapping operation sound, the tapping operation performed by the player does not match the instruction content of the instruction mark, but the erroneous timing determination is performed. The input operation is evaluated based on the processing result. Therefore, in the input type determination method of the present embodiment, the operation timing T1 is acquired when the operation timing T1 and the detection timing T2 are acquired in duplicate within the determination period Th for the sound input instruction mark. When the detection timing T2 is acquired within the delay time Td from the time, it is determined (evaluated) that the detection timing T2 of the tapping operation sound is not based on an appropriate input operation. On the other hand, when the operation timing and the detection timing are acquired in the determination period for the operation instruction mark, it is determined (evaluated) that the operation timing is based on an appropriate input operation.

  As another example, as shown in FIG. 8B, a plurality of input type determination periods Th1 to Th3 obtained by dividing the determination period Th for the sound input instruction mark are set in advance, and the same input type determination period is set. If the operation timing T1 and the detection timing T2 are acquired in the same manner, the detection timing T2 of the tapping operation sound is not based on an appropriate input operation. In other words, the detection timing T2 is erroneously You may make it determine (evaluate) that it is based on the performed tapping operation. Even in this case, when the operation timing and the detection timing are acquired in duplicate within the determination period for the operation instruction mark, the operation timing is based on an appropriate input operation (an input operation that matches the instruction content). Is determined (evaluated).

  As described above, according to the input type determination method of the present embodiment, in the system that causes the player to perform an input operation (tapping operation or applause) using the input interface having different input types, that is, the operation unit 162 and the sound detection unit 164, The tapping operation (operation) of the operation unit 162 and the applause (sound input operation) to the sound detection unit 164 can be accurately determined. In other words, it is possible to prevent an erroneous evaluation by judging an input unintended by the player, that is, an erroneous input as an appropriate input (an input that matches the instruction content).

2.32 Input Strength Determination Method for Player Input Operation Next, an input strength evaluation method for player input operation according to the present embodiment will be described. In this embodiment, as shown in FIGS. 4 and 5, the strong input operation and the weak input are performed for the strength condition of the tapping operation of the operation unit 162 and the volume condition of the applause in the operation instruction mark and the sound input instruction mark. The player is instructed separately for the operation. Therefore, regarding the strength of the tapping operation indicated by the operation instruction mark, the detected sound volume of the sound detecting unit 164 for the tapping operation sound of the operation unit 162 is used, and the strength of the applause sound indicated by the sound input instruction mark is determined. Employs an input intensity determination method that determines (evaluates) the input intensity based on the magnitude of each detected volume using the detected volume of the sound detection unit 164 for the sound generated by applause. Specifically, when a volume threshold (reference volume) is set in order to determine the magnitude of the detected volume, and a volume exceeding the threshold is detected by comparing the detected volume with the threshold, It is determined that a strong input operation (strong tapping operation or loud sound applause) has been made, and if a volume lower than the threshold is detected, it is determined that a weak input operation (weak tapping operation or low sound applause) has been performed. (evaluate.

  FIG. 9A shows the change over time of the detected sound volume acquired in the determination periods Th1 and Th2 for the two instruction marks. For example, it is assumed that a strong input operation is required in the determination period Th1, and a weak input operation is required in the determination period Th2. In this case, in the determination period Th1, an input operation (striking operation or applause) is performed at timing T1, and the detected volume LV1 at the timing T1 exceeds the reference volume LVth (threshold) for determining the volume level. ing. That is, it is determined that the input operation performed at the timing T1 is performed by the instructed strong input operation, and it is evaluated that an appropriate input operation is performed. In addition, in the determination period Th2, an input operation (striking operation or applause) is performed at timing T2, and the detected volume LV2 at the timing T2 is below the reference volume LVth (threshold). That is, the input operation performed at the timing T2 is determined to be performed by the instructed weak input operation, and it is determined (evaluated) that the appropriate input operation has been performed.

  On the other hand, in the case shown in FIG. 9A, for example, it is assumed that a weak input operation is required in the determination period Th1, and a strong input operation is required in the determination period Th2. In this case, it is determined that the input operation at the timing T1 performed within the determination period Th1 is not the instructed weak input operation, and it is evaluated that an erroneous input operation has been performed. Further, it is determined that the input operation at the timing T2 performed in the determination period Th2 is not the instructed strong input operation, and it is determined (evaluated) that the erroneous input operation has been performed.

  Here, since the sound detection unit 164 also detects ambient noise, when determining a weak input operation (weak tapping operation or clapping of a small sound), the tapping operation sound or applause sound is sure to be noise. Need to be distinguished. Therefore, in this embodiment, as shown in FIG. 9B, the first reference volume (first threshold) LVthH for determining the magnitude of the detected volume and the second reference volume for eliminating noise. By setting (second threshold) LVthL, if the detected sound volume exceeds the first reference volume LVthH without erroneously recognizing noise as an operation sound or applause sound, strong input It is evaluated (determined) that the operation has been performed, and if it belongs to the volume range between the first reference volume LVthH and the second reference volume LVthL, it can be evaluated (determined) that the weak input operation has been performed. The second reference volume may be adjusted according to the noise level (play environment) around the player.

  As described above, according to the method of the present embodiment, it is possible to determine the operation intensity of the operation unit 162 of the player and the loudness of the applause with a relatively simple configuration and processing, thereby improving the game characteristics of the music game. In addition, the input interface environment can be improved.

2.33 Timing Determination Method for Player Input Operation Next, a timing determination method for the player input operation according to this embodiment will be described. The player is required to perform an input operation (striking operation or applause) on the input unit (operation unit 162 or sound detection unit 164) at a reference timing at which the center of the instruction mark DM reaches the reference mark RM. In this embodiment, the timing determination process (operation) for comparing the input timing (operation timing or detection timing) of the input operation performed by the player during the instruction mark DM determination period with the reference timing and determining the degree of coincidence. Timing determination processing or detection timing determination processing). Then, this timing determination process evaluates whether or not the player satisfies the instruction content, and in the game system of the present embodiment, the evaluation of the player in three stages (“GREAT”, “OK”, “BAD”) is performed. A timing determination method for the input operation is adopted.

  Specifically, the timing determination method of this embodiment will be described in detail with reference to FIG. FIG. 10 shows an example of a timing determination method regarding the relationship between the positional relationship between the instruction mark DM and the reference mark RM and the determination period and the input timings t1 to t3.

  As shown in FIGS. 3A to 3C, the determination period for the instruction mark DM starts from the timing Ts when the head (one end) of the instruction mark DM reaches the reference mark RM. And end at the timing Te at which the tail end (the other end) reaches the reference mark RM. The determination period from the timing Ts to the timing Te is divided into a period in which it is determined as “GREAT”, a period in which it is determined as “OK”, and a period in which it is determined as “BAD”. The player's input timing is determined depending on whether it belongs. More specifically, a period including a timing (reference timing) in which the center of the instruction mark DM to be moved and the stationary reference mark RM overlap is set as a period in which the highest evaluation “GREAT” is obtained. Then, each period within the determination period is set so that the evaluation becomes lower in order of “OK” and “BAD” as the distance from the period increases. In the example shown in FIG. 6, when an input operation (striking operation or applause) is performed at timing t1, the input timing is determined as “BAD”, and when the input operation is performed at timing t2. The input timing is determined as “GREAT”, and when the input operation is performed at timing t3, the input timing is determined as “OK”.

  Note that the three-stage evaluation performed on the timing of the input operation of the player is appropriate on the condition that the input type and input intensity of the input operation of the player match the instruction content in the operation instruction mark or sound input instruction mark. To be done. That is, if the input type and the input intensity for the input operation of the player are determined to be an appropriate input operation (input operation that matches the instruction content), timing determination is performed. In this case, even if the player performs an input operation at any timing, for example, when the player mistakenly claps the operation instruction mark indicating that the operation unit 162 should be hit, for example, strong If the player performs a weak input operation even though the input operation is indicated by an instruction mark, the lowest evaluation may be determined as “BAD”. Therefore, according to the method of the present embodiment, it is possible to give a strong motivation for the player to perform a hitting operation or applause so as to satisfy the conditions of the input type and the input intensity determined.

3. Processing of this embodiment Next, a detailed processing example of this embodiment will be described with reference to the flowchart of FIG.

  First, a process for displaying a screen for the player to select a music game song is performed (step S10). Then, a process of reproducing and outputting music data corresponding to the music selected by the player is performed (step S11).

  Next, when it is determined that the display timing for the instruction mark (note) has arrived (Y in step S12), the image data of the operation instruction mark or the sound input instruction mark as described with reference to FIGS. Is read from the mark storage unit, and the movement process for each mark is performed and the display process is performed (step S13). That is, the instruction mark is moved on the line at a given moving speed. Note that the reference mark may be moved and displayed toward the instruction mark.

  Next, a process for acquiring the timing of the input operation (operation timing or detection timing) is performed (step S14). Subsequently, the detected sound volume of the sound detection unit at the timing acquired in step S14 is acquired (step S15). In step S14 and step S15, when the player performs an input operation (striking operation or applause) on the input device with respect to the instruction mark displayed by the movement process and display process of step S13, input data input by the player is displayed. For example, sampling is performed for each frame, and the sampled timing data detection volume data is held in the storage buffer.

  Next, input type processing is performed (step S16). That is, it is determined whether or not the operation timing and the detection timing held in the storage buffer are acquired in the same determination period, and whether the acquired operation timing and the detection timing are based on an appropriate input operation Evaluate whether or not.

  Next, a sound volume determination process is performed (step S17). That is, the detected volume held in the storage buffer is compared with the reference volume, the strength of the input operation is evaluated based on the strength of the player's tapping operation and the sound of the player's applause, and the player's input operation is instructed. Evaluate whether it is appropriate for the content.

  Next, a timing determination process is performed (step S18). That is, the operation timing or detection timing held in the storage buffer is compared with the reference timing stored in the storage unit. For example, as the difference between the operation timing or detection timing and the reference timing becomes smaller (as the operation timing or detection timing matches the reference timing), the comparison operation is performed so that the evaluation of the player's operation or sound input operation becomes higher. Process. In addition, when it is determined that the operation timing or the detection timing is not based on an appropriate input operation in the determination result of either the input type determination process or the volume determination process, the operation timing, the detection timing, and the reference timing Process to give the lowest rating regardless of the degree of match.

  Then, player score addition processing is performed (step S19). Specifically, the score corresponding to the evaluation of the input operation of the player by each determination process in steps S16 to S18 is added to the score of the player. Subsequently, it is determined whether or not the reproduction of the music data has ended (step S20). If it has not ended (N in step S20), the process returns to step S11. When the game has ended (Y in step S20), the final game result of the player is determined and displayed (step S21).
