Description

  The present invention relates to a game device, a game device control method, and a program that are suitable for outputting sound at an appropriate volume according to a user's operation status.

  Various techniques for switching voice processing according to various situations in which a user is placed have been developed. For example, in Patent Document 1, if a user operation is not detected for a predetermined time or more in a portable game machine, it is assumed that the user cannot operate the portable game machine in a public place, so that the user is not bored. A technique for reproducing audio data reproduced from headphones according to a predetermined order is disclosed. Similarly, in Patent Document 1, if the user's operation is not detected for a predetermined time or longer in the portable game machine, it is assumed that the user is in a situation where the user cannot operate the portable game machine in a private place. In view of this, a technique for lowering the volume of audio data that is currently being played back has been disclosed.

JP 2009-205101 A

  On the other hand, when playing back from the situation where the above processing is switched and played back to the original voice processing before switching, the original voice processing is appropriately performed according to the user's operation situation. There is a request to return to For example, if you turn the volume of the audio data down and play back immediately, if you immediately turn the volume back to the original volume, the volume will suddenly increase too much, causing annoyance to the surroundings, or the user may be surprised. It is possible that the situation becomes inappropriate.

  The present invention solves the above-described problems, and provides a game device, a game device control method, and a program suitable for outputting sound at an appropriate volume according to a user's operation situation. For the purpose.

  In order to achieve the above object, a game device according to a first aspect of the present invention includes a setting unit, an output unit, and a reception unit.

  The setting unit sets the output volume. That is, the setting unit sets the volume of sound output from the output unit described later. Here, for example, if an output volume with a large value is set, audio is output at a high volume at the output unit, and if an output volume with a small value is set, audio is output at a low volume at the output unit.

  The output unit outputs sound at the output volume. In other words, the output unit outputs various music pieces, sound effects, voices of people and animals, which are necessary for the progress of the game, or for enhancing the realism of the game. Such a sound is output from an output volume having a level set by the setting unit described above, for example, from a speaker or headphones connected to the game apparatus.

  The reception unit receives input from the user. That is, the accepting unit accepts various input operations for allowing the user to advance the game by using, for example, a controller connected to the game device or a remote controller that can be remotely operated.

Furthermore, the setting part
(A) When the elapsed time from the time when the last input is received from the user by the receiving unit exceeds a predetermined threshold time, the output volume is set to a predetermined minute volume,
(B) When the output volume is set to a predetermined minute volume and a new input is received from the user by the receiving unit, the output volume before the output volume is set to the predetermined minute volume (hereinafter referred to as “return volume”) Set to).

Here, the predetermined minute volume means a volume smaller than a volume (typically about 60 to 80 decibels) that is assumed to be output while the user is playing the game. For example, the setting unit sets in advance a value of 30 decibels as the predetermined minute volume.
Here, the new input means an input first received by the receiving unit in a state where the output volume is set to a predetermined minute volume and the output unit outputs sound at the predetermined minute volume. .

That is, the setting unit (a) does not play a game for some reason, such as when the user does not accept input for a predetermined threshold time or more, or the user is doing other business or is resting Therefore, it is determined that there is no need to output sound at a normal volume, and the output volume is set to a predetermined minute volume, 30 dB in the above example.
Further, the setting unit (b) does not play a game when a new input is received from the user by the reception unit while the output unit outputs sound at a predetermined minute volume set in this way. The setting unit returns the output volume to the original output volume before being set to a predetermined minute volume.

  With such a configuration, the game device of the present invention allows the volume to be lower than the normal play volume in a situation where the user is not playing a game and there is no need to output sound at a high volume, When is restarted, the volume is returned to the original volume and the sound is output. As a result, it is possible to output sound at an appropriate volume according to the user's operation status.

In the game device of the present invention,
The setting unit can set the output volume to be a predetermined minute volume, and when a new input is accepted, the output volume is gradually changed to return to the return volume.

  That is, when the input is newly received from the user by the receiving unit while the output unit is outputting sound at a predetermined minute volume, the setting unit instantaneously outputs the output volume at the timing when the input is newly received. Is set so that the output volume is gradually changed to return to the return volume over a return time (for example, 30 seconds) having a predetermined width.

  With such a configuration, the game device of the present invention may surprise the user or cause inconvenience to the surroundings by suddenly increasing the output volume from the state where the sound was output at a predetermined minute volume. Can be prevented.

In the game device of the present invention,
The setting unit can also set a longer time to return to the return volume as the elapsed time from when the last input is received until a new input is received is longer.

  That is, the setting unit does not set the time (return time) until returning to the return volume to a predetermined value, but the elapsed time from when the input is last received until the new input is received. Change accordingly. At this time, the setting unit predetermines a positive correlation between the elapsed time and the recovery time so that the recovery time becomes longer as the elapsed time becomes longer, and based on the correlation, that is, the elapsed time. The return time is set so that the longer the return time is, the shorter the elapsed time is, and the shorter the return time is. For example, when the elapsed time is 10 minutes, the return time is set to 1 minute, and the setting unit takes the time of 1 minute to return the output volume to the return volume. On the other hand, for example, when the elapsed time is 2 minutes, the return time is set to 10 seconds, and the setting unit returns the output volume to the return volume during the 10 seconds.

  The reason for this processing is as follows. That is, when the output unit outputs a sound at a predetermined minute volume for a short time, it is considered that a problem that surprises the user is unlikely to occur even if the output volume returns to the return volume in a short time. On the other hand, if the output unit is outputting a sound at a predetermined minute volume for a long time, the user may not be aware of the interrupted game, such as performing a task other than the game. If the output volume suddenly returns to the return volume, it is likely that the user will be surprised and the surrounding area will be disturbed. Therefore, the game apparatus of the present invention automatically sets an appropriate return time in consideration of such a user situation.

In the game device of the present invention,
After the new input is received, the setting unit sets a short time until the return volume is returned when the input is received from the user by the receiving unit, and returns to the return volume after the short set time. It is also possible to set by changing the output volume.

Here, the further input means an input accepted in a state where the output volume is changed so that the setting unit returns to the return volume.
That is, as described above, when a new input is received from the user in a state where sound is output at a predetermined minute volume, the setting unit starts to return the output volume to the return volume. On the other hand, here, when further input is received from the user while the output volume is returning toward the return volume, the setting unit sets the return time to be short, that is, shortens the return time. For example, when the return time is set to 1 minute in advance, the setting unit shortens the return time to 30 seconds by accepting further input. Then, the setting unit increases the degree of change in the output volume so that the output volume returns to the return volume after the shortened return time.

  Here, the further input from the user is not limited to one time. That is, the user may be able to further shorten the return time as the input volume is input many times while the output volume returns to the return volume.

  With such a configuration, when the user wants to return the output volume to the return volume at an early stage, the return time can be shortened by the user's own intention.

  In order to achieve the above object, a game apparatus control method according to a second aspect of the present invention is a control method executed by a game apparatus including a setting unit, an output unit, and a reception unit, and includes a setting step and an output step. And a reception process.

In the setting process, the setting unit sets the output volume.
In the output step, the output unit outputs sound at the output volume.
In the reception process, the reception unit receives input from the user.
Furthermore, in the setting process, the setting unit
(A) When the elapsed time from the time when the last input is received from the user by the receiving unit exceeds a predetermined threshold time, the output volume is set to a predetermined minute volume,
(B) When the output volume is set to a predetermined minute volume and a new input is received from the user by the receiving unit, the output volume is set to the output volume before being set to the predetermined minute volume.

  In order to achieve the above object, a program according to a third aspect of the present invention is configured to cause a computer to function as the above game device and to cause the computer to execute each step of the above control method.

  The program of the present invention can be recorded on a computer-readable information storage medium such as a compact disk, flexible disk, hard disk, magneto-optical disk, digital video disk, magnetic tape, and semiconductor memory.

  The program can be distributed and sold via a computer communication network independently of the computer on which the program is executed. The information storage medium can be distributed and sold independently from the computer.

  According to the present invention, it is possible to provide a game device, a game device control method, and a program that are suitable for outputting sound at an appropriate volume according to the user's operation status.

(Embodiment 1)
FIG. 1 is a schematic diagram showing a schematic configuration of a typical information processing device in which a game device according to an embodiment of the present invention is realized. Hereinafter, a description will be given with reference to FIG.

  The information processing apparatus 100 includes a central processing unit (CPU) 101, a read only memory (ROM) 102, a random access memory (RAM) 103, an interface 104, a controller 105, an external memory 106, and an image processing unit 107.

There is.

  The ROM 102 records an IPL (Initial Program Loader) that is executed immediately after the power is turned on, and when this is executed, the program recorded on the DVD-ROM is read out to the RAM 103 and execution by the CPU 101 is started. The The ROM 102 stores an operating system program and various data necessary for operation control of the entire information processing apparatus 100.

  The RAM 103 is for temporarily storing data and programs, and holds programs and data read from the DVD-ROM and other data necessary for game progress and chat communication. In addition, the CPU 101 provides a variable area in the RAM 103, performs an operation by directly operating the ALU on the value stored in the variable, and temporarily stores the value stored in the RAM 103 in a register. Performs an operation on the register and writes the result back to the memory.

  The controller 105 connected via the interface 104 receives an operation input performed when the user executes the game. For example, the controller 105 has a direction button used to input an operation indicating up, down, left, and right, and a button for inputting an instruction such as a determination operation, a cancel operation, and a menu display at a predetermined position on the surface. Is done. Each of these buttons is provided with a pressure sensor, and it is possible to detect which button is pressed. The user inputs an operation instruction to the information processing apparatus 100 by pressing such buttons arranged on the controller 105.

  The external memory 106 detachably connected via the interface 104 stores data indicating game play status (past results, etc.), data indicating the progress of the game, and log of chat communication in a network battle ( Data) is stored in a rewritable manner. The user can record these data in the external memory 106 as appropriate by inputting an instruction via the controller 105.

  A DVD-ROM mounted on the DVD-ROM drive 108 stores a program for realizing the game and image data and audio data associated with the game. Under the control of the CPU 101, the DVD-ROM drive 108 performs a reading process on the DVD-ROM loaded therein, reads out necessary programs and data, and these are temporarily stored in the RAM 103 or the like.

  The image processing unit 107 processes the data read from the DVD-ROM by an image arithmetic processor (not shown) included in the CPU 101 or the image processing unit 107, and then processes the processed data on a frame memory ( (Not shown). The image information recorded in the frame memory is converted into a video signal at a predetermined synchronization timing and output to a monitor (not shown) connected to the image processing unit 107. Thereby, various image displays are possible.

  The image calculation processor can execute a two-dimensional image overlay calculation, a transmission calculation such as α blending, and various saturation calculations at high speed.

  Also, polygon information arranged in the virtual three-dimensional space and added with various texture information is rendered by the Z buffer method, and the polygon arranged in the virtual three-dimensional space from the predetermined viewpoint position is determined in the direction of the predetermined line of sight It is also possible to perform high-speed execution of operations for obtaining rendered images.

  Further, the CPU 101 and the image arithmetic processor cooperate to draw a character string as a two-dimensional image in the frame memory or draw it on the surface of each polygon according to the font information that defines the character shape. Is possible. The font information is recorded in the ROM 102, but it is also possible to use dedicated font information recorded in the DVD-ROM.

  The NIC 109 is used to connect the information processing apparatus 100 to a computer communication network (not shown) such as the Internet, and is based on the 10BASE-T / 100BASE-T standard used when configuring a LAN (Local Area Network). To connect to the Internet using an analog modem, ISDN (Integrated Services Digital Network) modem, ADSL (Asymmetric Digital Subscriber Line) modem, cable television line A cable modem or the like and an interface (not shown) that mediates between these and the CPU 101 are configured.

  The audio processing unit 110 converts audio data read from the DVD-ROM into an analog audio signal and outputs the analog audio signal from a speaker (not shown) connected thereto. Further, under the control of the CPU 101, sound effects and music data to be generated during the progress of the game are generated, and sound corresponding to this is output from the speaker.

  When the audio data recorded on the DVD-ROM is MIDI data, the audio processing unit 110 refers to the sound source data included in the audio data and converts the MIDI data into PCM data. If the compressed audio data is in ADPCM format or Ogg Vorbis format, it is expanded and converted to PCM data. The PCM data can be output by performing D / A (Digital / Analog) conversion at a timing corresponding to the sampling frequency and outputting it to a speaker.

  Furthermore, a microphone 111 can be connected to the information processing apparatus 100 via the interface 104. In this case, the analog signal from the microphone 111 is subjected to A / D conversion at an appropriate sampling frequency so that processing such as mixing in the sound processing unit 110 can be performed as a PCM format digital signal.

  When the information processing apparatus 100 is used as a karaoke apparatus, audio data read from a DVD-ROM or audio data acquired from a computer communication network via the NIC 109 is used as accompaniment data, and audio input from the microphone 111 is used. The voice processing unit 110 mixes the accompaniment data and the singing data with the data as the singing data, and outputs it from the speaker. Moreover, it is possible to output sound using headphones (not shown) or earphones (not shown) instead of the speakers.

  Further, the information processing apparatus 100 can measure time using a predetermined synchronization timing when the image processing unit 107 displays an image on a monitor. That is, since the output of the image information to the monitor is performed every predetermined cycle t seconds (for example, 1/60 seconds), by counting the number of times of output with the counter variable prepared in the RAM 103, Time can be measured. In addition, the information processing apparatus 100 may include an RTC (Real Time Clock) therein and may be used for processing for time measurement.

  In addition, the information processing apparatus 100 uses a large-capacity external storage device such as a hard disk so as to perform the same function as the ROM 102, the RAM 103, the external memory 106, the DVD-ROM mounted on the DVD-ROM drive 108, and the like. You may comprise.

  Further, it is possible to adopt a form in which a keyboard for accepting a character string editing input from a user, a mouse for accepting various position designations and selection inputs, and the like are connected. In addition, a general-purpose personal computer can be used instead of the information processing apparatus 100 of the present embodiment.

  The information processing apparatus 100 described above corresponds to a so-called “consumer video game apparatus”, but the present invention can be realized as long as it performs image processing to display a virtual space. Therefore, the present invention can be realized on various computers such as a mobile phone, a portable game device, a karaoke apparatus, and a general business computer.

  For example, a general computer includes an CPU, a RAM, a ROM, a DVD-ROM drive, and an NIC as in the information processing apparatus 100, and an image processing unit having a simpler function than the information processing apparatus 100. In addition to having a hard disk as an external storage device, a flexible disk, a magneto-optical disk, a magnetic tape, and the like can be used. Further, not the controller 105 but a keyboard or a mouse is used as an input device.

  FIG. 2 is a schematic diagram showing a schematic configuration according to the game device of the present invention. The game apparatus 200 of the present invention is typically realized by the information processing apparatus 100 described above. Hereinafter, the general configuration will be described with reference to this figure.

  The game device 200 includes a setting unit 201, an output unit 202, and a reception unit 203.

  The setting unit 201 sets the output volume. The output volume set here is supplied to the output unit 202 described later, and the sound is output at the set output volume. For example, the setting unit 201 is realized by the CPU 101 cooperating with the RAM 103 or the like.

  The output unit 202 outputs sound at the output volume. Here, the output volume set by the setting unit 201 described above is received, and the audio is output to the user at the output volume. Such an output unit 202 is realized, for example, by the function of the sound processing unit 110 controlled by the CPU 101.

  The accepting unit 203 accepts input from the user. Here, the user receives various input operations for advancing the game, and notifies the setting unit 201 of the input information. Such a reception unit 203 is realized by the function of the controller 105 connected via the interface 104, for example.

  Note that the game device 200 also includes a storage unit as a storage area for various data and a timer unit for measuring time as appropriate. The storage unit is realized by the RAM 103 or the like, and stores data necessary for the configuration / progress of the game, such as the current time, user input contents, and input time. The time measuring unit is realized by the functions of the image processing unit 107, the RAM 103, and the like, and the time can be measured by counting the number of times of output using the fact that the image information is output to the monitor every predetermined period. Or when game device 200 is provided with RTC, time may be measured by RTC.

  Furthermore, the setting unit 201 sets the output volume to a predetermined minute volume when (a) the elapsed time from the time when the last input is received from the user by the receiving unit 203 exceeds a predetermined threshold time, (b) When the output volume is set to a predetermined minute volume and a new input is received from the user by the receiving unit 203, the output volume before the output volume is set to the predetermined minute volume (hereinafter referred to as "return volume"). ).

  Here, the predetermined threshold time corresponds to an optimum time for determining that the user is not playing the game because there is no input from the user. For example, a value of 3 minutes is stored in advance in the storage unit. Be prepared. The predetermined minute volume corresponds to a volume smaller than a volume (typically about 60 to 80 decibels) assumed to be output while the user is playing the game. A value of 30 decibels is prepared in advance in the storage unit.

  That is, the setting unit 201 measures the elapsed time after the last input is received from the user by the receiving unit 203 using the function of the time measuring unit, and determines whether or not a predetermined threshold time is exceeded. If it has exceeded, the output volume is set to a predetermined minute volume. At this time, the setting unit 201 temporarily stores the output volume before setting the predetermined minute volume in the storage unit as the return volume. Then, the setting unit 201 sets the output volume to the stored return volume when a new input is received from the user by the receiving unit 203 with the output volume set to a predetermined minute volume in this way. . Hereinafter, a specific description will be given with reference to FIGS. 3 and 4.

  FIG. 3 is a graph showing the relationship between the output volume and the elapsed time in the game apparatus 200 of the present invention, and is a graph showing how the output volume is set to a predetermined minute volume. In this figure, the vertical axis is the output volume (volume is louder toward the top) and the horizontal axis is the elapsed time (later time is toward the right), and the output volume is set to any value over time. Indicate.

  FIG. 3 shows that the output unit 202 outputs sound at a certain volume 301 (80 decibels in this figure), and the four times of the input 302a, the input 302b, the input 302c, and the input 302d as time passes. The case where the input unit 203 receives an input from the user is shown. That is, a situation is shown in which the user performs four input operations in order using the controller 105 of the game apparatus 200 in order to advance the game. Such an input operation is performed by, for example, pressing a direction key of the controller 105 to move a character in a role playing game, an action game, or a sports game, or pressing a predetermined button of the controller 105 to attack an enemy character. It corresponds to the operation to do. For example, this corresponds to an operation of pressing a predetermined button of the controller 105 in order to select a song to be sung in a karaoke game or to input a quiz answer in a quiz game.

The setting unit 201 starts measuring time using the function of the time measuring unit each time such inputs 302a to 302d are received. Then, it is determined whether or not the measured time has passed a predetermined threshold time 303. Specifically, it is assumed that the predetermined threshold time 303 is set to 3 minutes. At this time, the setting unit 201
(1) First, start measuring the elapsed time since the first input 302a was made,
(2) Next, when the second input 302b is made, since the measured elapsed time has not reached 3 minutes, the measured elapsed time is reset, and the elapsed time is started again from zero.
(3) When the third input 302c is made, since the measured elapsed time has not reached 3 minutes, the measured elapsed time is reset, and the elapsed time is again measured from zero.
(4) Further, when the fourth input 302d is made, the measured elapsed time does not reach 3 minutes, so the measured elapsed time is reset and the elapsed time is again measured from zero.

  After that, in FIG. 3, since the next input is not accepted even after a predetermined threshold time 303 of 3 minutes has elapsed, the setting unit 201 changes the output volume from the previous volume 301 to the predetermined time at the switching time 306. The sound volume is changed to a minute volume 304. That is, the setting unit 201 sets the output volume to a predetermined minute amount when the elapsed time from the time when the last input 305 (in this case, the input 302d) from the user is received by the receiving unit 203 exceeds a predetermined threshold time 303. The volume is set to 304 (30 dB in this figure). That is, the sound volume that was 80 decibels until then is lowered to 30 decibels. Thereafter, the output unit 202 outputs sound while the output volume is set to 30 dB, that is, the predetermined minute volume 304.

  As described above, the game device 200 is not playing a game for some reason, such as when the user is doing other tasks or is resting, and the user is playing the game at a normal volume 301. It is determined that there is no need to output sound, and the volume of the output sound is set to a lower volume than that during the normal game play, that is, a predetermined minute volume 304.

  After the output unit 202 is in a state of outputting sound at the predetermined minute volume 304 as described above, when a new input is received from the user by the receiving unit 203, the setting unit 201 in this embodiment sets the output volume. The output volume (return volume) before being set to a predetermined minute volume 304 is set. Hereinafter, a description will be given with reference to FIG.

  FIG. 4 is a graph showing the relationship between the output volume and the elapsed time in the game apparatus 200 of the present invention, and is a graph showing how the output volume is set to the return volume. As in FIG. 3, this figure is a graph showing the output volume on the vertical axis and the elapsed time on the horizontal axis, and what value the output volume is set with the passage of time. It is a graph which shows a mode after the output volume changes to the predetermined minute volume 304. FIG.

  That is, in FIG. 4, the input 302 d from the user is accepted as the last input 305, and thereafter there is no input operation from the user for a predetermined threshold time 303, and the output volume is changed from the previous volume 301 at the switching time 306. A situation where the sound volume is changed to a predetermined minute volume 304 is shown. At this time, the setting unit 201 of the game device 200 temporarily stores the sound volume 301 that has been output so far in a storage unit such as the RAM 103 as the return sound volume 308 in order to use in the process of returning the output sound volume described later. Keep it.

  In FIG. 4, the output volume thereafter is kept at a predetermined minute volume 304 and is kept constant until the next input 302e is received from the user. That is, until the next time a new input is received from the user, the game device 200 determines that the user is not playing a game, and the output unit 202 has a volume lower than that for playing the normal game (30 dB in this figure). ) To continue outputting audio.

  When the receiving unit 203 receives an input 302e from the user, that is, a new input 309 in a state where the output volume is a predetermined minute volume 304, the setting unit 201 reads the return volume 308 stored in the storage unit. Then, the output volume that has been the predetermined minute volume 304 is set as the return volume 308. That is, the output volume is returned to the volume 301 before being set to the predetermined minute volume 304.

  At this time, the setting unit 201 gradually changes so that the output volume reaches the return volume 308 after the return time 310, instead of instantaneously changing the output volume to the return volume 308, as shown in FIG. Let That is, in this embodiment, a predetermined return time 310 (one minute in the figure) having a certain width is determined in advance, and the setting unit 201 gradually changes the output volume when a new input 309 is received. Thus, the setting is made to return to the return volume 308 after the return time 310. For this purpose, the setting unit 201 first determines the change rate 312 of the output volume.

Here, the rate of change 312 means the amount by which the output volume changes per unit time. That is, as shown in this figure, when the output volume changes linearly from the predetermined minute volume 304 to the return volume 308 over the return time 310, the rate of change 312 is:
(Return volume 308 -predetermined minute volume 304) / return time 310
Is calculated as In this figure, the return volume 308 is 80 decibels, the predetermined minute volume 304 is 30 decibels, and the return time 310 is 1 minute, so by applying the above equation,
A rate of change 312 of (80 decibels-30 decibels) / 1 min = 50 decibels / min is obtained. The setting unit 201 changes the output volume based on the change rate 312 obtained in this way, thereby returning the output volume to the return volume 308 after the return time 310.

  This makes it difficult for the output unit 202 to output a sound at a predetermined minute volume 304, so that the sound volume is suddenly increased and the sound is not output, and the user is surprised and annoying the surroundings. Can be prevented.

  FIG. 5 is a flowchart showing a flow of processing according to the game device 200 of Embodiment 1 of the present invention. The flow of processing realized in the game device 200 in the present embodiment that has been described so far will be described below.

  First, the CPU 101 of the game device 200 performs various initialization processes (step S101). Here, various information such as images and sounds necessary for starting a game played by the user is read from a DVD-ROM or the like using the DVD-ROM drive 108, or received from the user by the controller 105 or the like. . The output volume level of the sound output in the game is also initialized here.

  Then, when the game is started, the game device 200 starts measuring elapsed time (step S102). That is, by using the function of the time measuring unit, the measurement of the elapsed time necessary for automatically adjusting the magnitude of the output volume described later is started here.

  Further, the output unit 202 outputs sound at the set output volume (step S103). Here, sounds such as various music pieces, sound effects, and voices necessary for playing the game are output at the output volume initially set in step S101.

  And the game device 200 determines whether the reception part 203 received the input from the user (step S104). That is, it is determined by the controller 105 or the like whether the user has input various operations for playing the game.

  If there is an input from the user (step S104; YES), the process returns to step S102, starts measuring elapsed time again, and outputs sound at the set output volume. That is, every time the user inputs, the value of the elapsed time measured until step S104 is reset, and the elapsed time starts to be measured again from the beginning.

  In addition, in the input of step S104, when the user performs an input to change the output volume, such as increasing or decreasing the volume of the voice, in step S103 after the process returns to step S102, Audio is output at the changed output volume.

  If there is no input from the user in step S104 (step S104; NO), the game device 200 next determines whether or not the measured elapsed time has exceeded a predetermined threshold time 303 (step S105). That is, it is checked whether the elapsed time when the measurement is started in step S101 exceeds a predetermined threshold time 303 at this time.

  If not yet exceeded (step S105; NO), the process returns to step S103. That is, in a state where the elapsed time has not yet exceeded the predetermined threshold time 303, the sound is output at the set output volume, and it is continuously determined whether there is an input from the user. Each time there is an input from the user, the elapsed time is measured again from the beginning. This state corresponds to a state in which a so-called user normally plays a game. That is, since the user frequently performs operation input to advance the game and the elapsed time is reset each time, the elapsed time does not exceed the predetermined threshold time 303.

  On the other hand, if the measured elapsed time exceeds the predetermined threshold time 303 (step S105; YES), the setting unit 201 of the game device 200 temporarily stores the current output volume as the return volume 308 in the storage unit. The output volume is set to a predetermined minute volume 304 (step S106). Then, the output unit 202 outputs sound at the set predetermined minute volume 304 (step S107). This state is considered to be a state in which a predetermined threshold time 303 has elapsed since the last input 305 was received, and the so-called user has interrupted play. Therefore, the output volume is lowered to a predetermined minute volume 304, and the sound is output with a volume lower than that for normal play.

  In this state, the game device 200 further determines whether the receiving unit 203 has received an input from the user (step S108). That is, it is checked whether a new input 309 has been received from the user in a state where sound is output at a predetermined minute volume 304.

  If not received (step S108; NO), the process returns to step S107, and the output unit 202 continues to output sound at a predetermined minute volume 304. That is, unless an input from the user is accepted, it is determined that the user continues to interrupt the play, and the sound is continuously output with the predetermined minute volume 304.

  On the other hand, when a new input 309 is received from the user (step S108; YES), the process proceeds to a process of returning the output volume to the return volume 308. First, here, the setting unit 201 of the game apparatus 200 reads the return volume 308 temporarily stored in the storage unit, and changes the volume so that the output volume reaches the return volume 308 after a predetermined return time 310. The rate 312 is determined (step S109).

  Thereafter, the setting unit 201 changes and sets the output volume based on the determined change rate 312 (step S110), and the output unit 202 outputs the sound with the changed output volume (step S110). S111). Then, it is determined whether the changed output volume has reached the return volume 308 (step S112). If not reached (step S112; NO), the process returns to step S110 again, and the setting unit 201 changes the output volume. That is, until the output volume reaches the return volume 308, the volume of the output audio gradually changes based on the determined change rate 312.

  If the output volume reaches the return volume 308 (step S112; YES), the process returns to step S102. That is, the process returns to the state where the so-called user is normally playing the game, and the processing of this flowchart after step S102 is repeated.

  With such a configuration, in the first embodiment, in a situation where the user is not playing a game and there is no need to output sound at a high volume, the volume is set to a predetermined minute volume 304, and then the user plays the game. When resumed, the output sound is returned to the return volume 308 over a predetermined return time 310. As a result, it is possible to output sound at an appropriate volume according to the user's operation status.

(Embodiment 2)
Next, Embodiment 2 of the present invention will be described. In the first embodiment, the output sound volume returns from the predetermined minute sound volume 304 to the return sound volume 308 over a predetermined return time 310 having a fixed value. On the other hand, in the present embodiment, the setting unit 201 sets the return time 310 longer as the elapsed time (interruption time) from when the last input 305 is received until the new input 309 is received is longer. That is, the interruption time and the return time 310 have a positive correlation, and the return time 310 is set based on the correlation. This will be specifically described with reference to FIG.

  FIG. 6 is a graph showing the relationship between the output sound volume and the elapsed time in the game apparatus 200 of the present invention, and shows how the return time changes based on the interruption time. The components in this figure are the same as those in FIG. 4, but the output volume is a predetermined minute volume 304 according to the length of the interruption time 311 from when the last input 305 is received until a new input 309 is received. The length of the return time 310 for returning from the return to the return volume 308 has changed.

  Specifically, in both FIG. 6 (a) and FIG. 6 (b), the input is not accepted for a predetermined threshold time 303 after the last input 305 is accepted from the user, and the output volume is the volume 301 (80 dB). ) To a predetermined minute volume 304 (30 dB). In both figures, a new input 309 is accepted from the user thereafter, but in FIG. 6B, a new input 309 is received at a longer time interval from the last input 305 than in FIG. 6A. Accepted. That is, the interruption time 311b (8 minutes in this figure) is longer than the interruption time 311a (5 minutes in this figure).

  After such a new input 309 is received, the setting unit 201 changes the output volume set to the predetermined minute volume 304 to return to the return volume 308 over the return time 310. At this time, the setting unit 201 sets the value of the return time 310 so that the return time 310 becomes longer as the interruption time 311 is longer. That is, the setting unit 201 sets a positive correlation between the value of the interruption time 311 and the return time 310 and the value in advance, and determines the value of the return time 310 based on the correlation. Specifically, when FIG. 6A is compared with FIG. 6B, the interruption time 311b is longer than the interruption time 311a, and accordingly, the return time 310b (in this figure, 4 minutes). Is longer than the return time 310a (2 minutes in this figure).

  As described above, when the return time 310a and the return time 310b are determined based on the interrupt time 311a and the interrupt time 311b, the output sound volume returns from the predetermined minute sound volume 304 set when the new input 309 is received. A rate of change 312a and a rate of change 312b that return to the volume 308 with the determined return volume 310a and return time 310b are determined. Then, as shown in FIGS. 6A and 6B, the output volume changes at the rate of change 312a and the rate of change 312b from when the new input 309 is received, and the return time 310a and It returns to the return volume 308 after the return time 310b.

  That is, when the interruption time 311 is short, it is considered that a problem that surprises the user hardly occurs even if the output volume is returned to the return volume 308 in a short time. Therefore, the setting unit 201 returns the output volume to the return volume 308 with a relatively large change rate 312. On the other hand, if the interruption time 311 is long, there is a high possibility that the user is not aware of the interrupted game, for example, because he / she is doing anything other than a game, and the output volume suddenly returns to the return volume 308. Doing so is likely to surprise the user and cause trouble to the surroundings. Therefore, the setting unit 201 returns the output volume to the return volume 308 with a relatively small change rate 312.

  With such a configuration, the game device 200 according to the second embodiment has a relatively large change rate 312 when the interruption time 311 when the user has not played a game is short, while the interruption time when the user has not played a game. When 311 is long, the output volume can be returned to the return volume 308 automatically at an appropriate change rate 312 according to the user's situation.

  FIG. 7 is a flowchart showing a flow of processing according to the game device 200 of Embodiment 2 of the present invention. The flow of processing realized in the game device 200 in the present embodiment that has been described so far will be described below. Note that the flowchart in the present embodiment follows the flowchart in the first embodiment (FIG. 5), and in this diagram, the processing of step S201 (the portion surrounded by a dotted line in the diagram) is newly added. .

  That is, the processing of steps S101 to S112 is the same as that of the above-described first embodiment in this embodiment, but in this embodiment, a new sound is output from the user in a situation where sound is output at a predetermined minute volume 304. When the input 309 is accepted (step S108; YES), the process proceeds to a unique process.

  At this time, in the game device 200 according to the present embodiment, the setting unit 201 determines the return time 310 based on the interruption time 311 (step S201). That is, the setting unit 201 sets the interruption time 311 based on the elapsed time (interruption time 311) from the last input 305 o'clock received in step S104 to the new input 309 o'clock received in step S108. The longer the return time 310 is set, the longer.

  Thereafter, the process proceeds to step S109. That is, the change rate 312 is determined so as to reach the return volume 308 after the return time 310 determined in step S201 (step S109), and the output volume is changed based on the determined change rate 312 (step S110). That is, based on the determined length of the return time 310, the change rate 312 is determined so that the output volume returns to the return volume 308 after the return time 310, and the output volume is changed at the determined change rate 312. The change rate 312 determined here becomes smaller as the return time 310 determined in step S201 is longer, and becomes larger as the determined return time 310 is shorter.

  Thereafter, the game device 200 outputs a sound with the changed output volume (step S111), and determines whether the output volume has reached the return volume 308 (step S112). If not reached (step S112; NO), the process returns to step S110, the output volume is changed, and the sound is continuously output at the changed output volume. If it arrives (step S112; YES), the process returns to step S102, and the process of this flowchart after step S102 is repeated.

  With such a configuration, the game apparatus 200 according to the second embodiment increases the output volume over a longer recovery time 310 as the elapsed time from when the last input 305 is received until the new input 309 is received is longer. Return to return volume 308. As a result, when the time when the user has interrupted the game is short, it is automatically appropriate according to the situation of the user, such as slowly when the time when the user has interrupted the game is long. The output volume can be returned to the return volume 308 at a speed.

(Embodiment 3)
Next, a third embodiment of the present invention will be described. In the first embodiment and the second embodiment, the output sound volume returns from the predetermined minute sound volume 304 to the return sound volume 308 with a predetermined return time 310 or a return time 310 corresponding to the interruption time 311. In the present embodiment, the return time 310 for the output sound volume to return to the return sound volume 308 is shortened according to the input from the user.

  FIG. 8 is a graph showing the relationship between the output sound volume and the elapsed time in the game apparatus 200 of the present invention, and shows how the return time 310 is shortened. This graph is a graph showing what value the output volume is set with the passage of time, with the output volume on the vertical axis and the elapsed time on the horizontal axis, similar to the graph in the embodiment described above. is there.

  In FIG. 8, the process starts from a state where the output volume is set to a predetermined minute volume 304. That is, the state from the state after the input from the user is not accepted for the predetermined threshold time 303 and the setting unit 201 sets the output sound volume to the predetermined minute sound volume 304 will be described. In FIG. 8, when the input 302 e from the user is accepted as a new input 309 in this state, the output volume starts to change back to the return volume 308 as in the first embodiment. That is, the rate of change 312e is determined so that the output volume reaches the return volume 308 over the return time 310e, and the output volume changes with the passage of time by the rate of change 312e.

  In the present embodiment, when the input 302f is further received from the user, the amount of change in the output volume increases. In other words, in the present embodiment, when the setting unit 201 receives a new input 309 and then receives a further input 302f from the user by the receiving unit 203, the setting unit 201 shortens the return time 310e to the return time 310f. The output volume is changed so as to return to the return volume 308 after time 310f.

  At this time, the change rate 312e of the output volume increases to the change rate 312f in response to the return time 310e being shortened to the return time 310f. That is, the setting unit 201 re-determines the rate of change in order to return the output volume to the return volume 308 with a shorter recovery time, and changes the output volume with the passage of time by the re-determined rate of change 312f.

  Here, the amount of reduction time when the return time 310e is shortened to the new return time 310f may be determined in any way. For example, a new reduction time 310f may be obtained by setting a predetermined reduction time in advance and subtracting the predetermined reduction time from the original return time 310e. Alternatively, a predetermined reduction rate (a real number greater than 0 and less than 1) may be determined in advance, and the new return time 310f may be obtained by multiplying the original return time 310e by this predetermined reduction rate.

  Further, in the present embodiment, the additional input 302f accepted from the user is not limited to one time while the output volume returns from the predetermined minute volume 304 toward the return volume 308. That is, the return time 310 may be changed to a shorter time as the user inputs more times. Hereinafter, a description will be given with reference to FIG.

  FIG. 9 is a graph showing the relationship between the output volume and the elapsed time in the game apparatus 200 of the present invention, and is a graph showing how the return time 310 is further shortened. The components in this figure are basically the same as those in the graph of FIG. 8 described above, but this figure shows a state when an input 302g is further received after a further input 302f is received from the user. Yes.

  Specifically, in FIG. 9, the output volume is initially set to a predetermined minute volume 304, and after receiving an input 302e from the user as a new input 309, the output volume returns to the return volume 308 at a return time 310e. , Increasing at the rate of change 312e. In this figure, while the output volume is increasing as described above, two inputs such as an input 302f and an input 302g are accepted from the user. At this time, the recovery time is gradually shortened from the initial recovery time 310e to a recovery time 310f and a recovery time 310g. The rate of change determined based on the return time gradually increases from the initial rate of change 312e to a rate of change 312f and rate of change 312g.

  In other words, the more the input is received from the user while the output volume is changing toward the return volume 308, the more the output volume increases its rate of change 312 and the immediate return to the return volume 308. It will be.

  With such a configuration, when the user wants to immediately return the output volume from the predetermined minute volume 304 to the return volume 308, the user can quickly return to the return volume 308 by repeating the input many times.

  FIG. 10 is a flowchart showing a flow of processing according to the game device 200 of Embodiment 3 of the present invention. The flow of processing realized in the game device 200 in the present embodiment that has been described so far will be described below. Note that the flowchart in this embodiment follows the flowchart in the second embodiment (FIG. 7), and in this figure, the processing of steps S301 to S302 (the part surrounded by the dotted line in this figure) is newly added. ing.

  That is, the processing of steps S101 to S112 and S201 is the same as that of the second embodiment described above in this embodiment, but in this embodiment, the output volume returns from the predetermined minute volume 304 to the return volume 308. When the output volume has not yet reached the return volume 308 (step S112; NO), the process proceeds to an original process.

  At this time, the game device 200 in the present embodiment determines whether the receiving unit 203 has received an input from the user (step S301). That is, it is checked whether there is an input from the user while the output volume is returning to the return volume 308.

  Here, if the input is not accepted (step S301; NO), nothing is performed here, and the process returns to step S110. That is, as long as there is no input from the user while the output volume is returning to the return volume 308, the setting unit 201 sets the output volume until the return volume 308 is reached, as in the flowchart of FIG. Is continuously changed at the rate of change 312 determined in step S109, and the output unit 202 continues to output sound at the changed volume.

  On the other hand, when the input is accepted (step S301; YES), the setting unit 201 of the game device 200 in the present embodiment shortens the return time 310 and reaches the return volume 308 after the shortened return time 310. Thus, the change rate 312 is determined again (step S302). That is, if there is an input from the user while the output volume is returning to the return volume 308, in the present embodiment, the setting unit 201 quickly returns the output volume to the return volume 308. The change rate 312 that has changed is made larger than before.

  Thereafter, the process returns to step S110. That is, the setting unit 201 changes the output volume based on the change rate 312 increased in step S302 (step S110), and the output unit 202 outputs the sound with the changed volume (step S111). Then, the process again proceeds to step S112, and if the changing output volume does not reach the return volume 308 (step S112; NO), it is further determined whether the receiving unit 203 has received an input from the user (step S112). If it has been received (step S301; YES), the rate of change 312 is further increased (step S302).

  That is, the game device 200 according to the present embodiment repeats the processes of steps S301 to S302 and steps S110 to S112 every time there is an input from the user until the output volume reaches the return volume 308, and the output volume is set. The rate of change 312 is increased, and the time for the output volume to reach the return volume 308 is advanced.

  With such a configuration, the game apparatus 200 according to the third embodiment not only automatically adjusts the output volume, but also allows the user to restore the return volume at an early stage without his own intention, that is, without waiting for the predetermined return time 310. If it is desired to return to 308, further input can be performed to quickly return to the return volume 308. As a result, the volume of the output voice can be adjusted more flexibly according to the user's situation.

(Other embodiments)
As mentioned above, although embodiment of this invention was described, this invention is not limited to embodiment mentioned above, A various deformation | transformation and application are possible. Moreover, it is also possible to freely combine the constituent elements of the above-described embodiments.

  For example, in the above embodiment, as shown in FIG. 3, at the switching time 306, the output volume instantaneously changed from the volume 301 to the predetermined minute volume 304. However, the present invention is not limited to this, and the output volume may gradually change to a predetermined minute volume 304 over time. Hereinafter, a description will be given with reference to FIG.

  FIG. 11 is a graph showing the relationship between the output volume and the elapsed time in the game apparatus 200 of the present invention, and is a graph showing how the output volume is gradually set to a predetermined minute volume 304. This figure is basically the same graph as FIG. 3, with the output volume on the vertical axis and the elapsed time on the horizontal axis, and a graph showing what value the output volume is set over time. is there.

  In FIG. 11, as in FIG. 3, after four inputs 302 a to 302 d, there is no input for a predetermined threshold time 303, and the output volume changes from the volume 301 to the predetermined minute volume 304. However, here, the setting unit 201 does not change the sound volume 301 to the predetermined minute volume 304 instantaneously at the switching time 306 as shown in FIG. Over time.

  In FIG. 11, the output volume changes from the volume 301 to the predetermined minute volume 304 over a predetermined switching time 307 at a constant rate of change (linearly in the graph). However, the rate of change may increase at a previous time within the predetermined switching time 307, or may increase at a later time within the predetermined switching time 307.

  By gradually changing the output volume to the predetermined minute volume 304 in this manner, the output unit 202 outputs the sound at the predetermined minute volume 304 from the state where the output unit 202 outputs the sound at the normal output volume. Therefore, the transition can be made smoothly without making the user feel unnatural.

  Further, in the above embodiment, as shown in FIG. 4, the change from the predetermined minute volume 304 to the return volume 308 takes a return time 310 and changes at a constant change rate 312 (linearly in the graph). However, the present invention is not limited to this, and any change may be made as long as the return to the return volume 308 is made after the return time 310 after the new input 309 is accepted.

For example, FIG. 12A shows a state in which the rate of change of the output volume increases with the later time within the return time 310. That is, when the output volume changes from the predetermined minute volume 304 to the return volume 308, the amount of change in the output volume per unit time was initially small, but the output volume changes as the return volume approaches the return volume 308. The amount to do is getting bigger.
On the other hand, FIG. 12B shows how the rate of change of the output volume becomes smaller at later times within the return time 310. That is, when the output volume changes from the predetermined minute volume 304 to the return volume 308, the amount of change in the output volume per unit time is large at first, but changes as the output volume approaches the return volume 308. The amount to do is small.
Further, FIG. 12 (c) shows a state in which the output volume changes in a staircase pattern. That is, the output volume does not continuously change as in FIGS. 4, 12 (a), and 12 (b), but in FIG. 12 (c), the output is output at several predetermined times. The volume is increased to the return volume 308 while discontinuously changing from a certain volume to the next volume.
Thus, in the present invention, for example, the output volume may be changed to the return volume 308 in the manner of change as shown in FIGS. 12 (a) to 12 (c).

  As described above, it is possible to provide a game device, a game device control method, and a program that are suitable for outputting sound at an appropriate volume according to a user's operation status.
