The output interface 107 outputs video or audio of the game. For example, the output interface 107 is a display device or an audio output device.

Note that the game execution device 101 only needs to be able to acquire the output of the biological information detection device 105, and the biological information detection device 105 may be a separate device from the game execution device 101 (a device connected to the game execution device 101). There may be. Similarly, the game execution device 101 only needs to be able to acquire the output of the input interface 106, and the input interface 106 may be a separate device from the game execution device 101. The game execution device 101 only needs to be able to output information (for example, video information or audio information of the game) to the output interface 107, and the output interface 107 may be a separate device from the game execution device 101.

FIG. 2 is a hardware configuration diagram of the game execution device 101. The game execution device 101 includes a control unit 201, a calculation device 202, a memory 203, an SSD (Solid State Drive) 204, a graphic calculation device 205, an external memory 206, and a communication device 207. Furthermore, the game execution device 101 includes a biological information detection device 208, a controller 209, a microphone 210, a display device 211, and an audio output device 212. The above hardware other than the control section 201 is connected to the control section 201.

The control unit 201 controls each unit of the game execution device 101. For example, the control unit 201 controls the computing device 202, the graphic computing device 205, and the communication device 207 to execute the game. The calculation device 202 is a device that performs various calculations. Memory 203 temporarily stores various information.

The graphic calculation device 205 is a device that performs graphic calculation. The communication device 207 communicates with external devices.

For example, a game program (program file) is stored in the SSD 204 in advance. The arithmetic unit 202 reads the program from the SSD 204, expands it to the memory 203, and executes it. Note that the program may be stored in advance in the external memory 206 or in another storage device (for example, an HDD (Hard Disc Drive)). The calculations according to the program are performed by the calculation device 202, but the graphic calculations for the game are performed by the graphic calculation device 205. The control unit 201 controls the communication device 207 to communicate with the game server 102, performs synchronization processing of data necessary for executing the game, and executes the game.

The biological information detection device 208 detects (acquires) and outputs the user's biological information. The biological information detection device 208 corresponds to the biological information detection device 105 in FIG. For example, the biological information detection device 208 is an electroencephalogram detection device that is attached to the user's head and detects the user's brain waves. The biological information detection device 208 may be a detection device that is worn on the user's arm or finger and detects the user's heart rate, perspiration, or blood pressure.

The controller 209 is an input device used for operating the game (for example, operating a character in the game). Controller 209 corresponds to input interface 106 in FIG. Controller 209 may or may not be a game pad. For example, as the controller 209, at least one of a keyboard and a mouse may be used.

The microphone 210 is an input device used to input the user's voice to the game execution device 101. Microphone 210 also includes input interface 106 in FIG.

The display device 211 displays video of the game. Display device 211 corresponds to output interface 107 in FIG. The display device 211 may be a stationary display device (for example, a PC monitor) or a head-mounted display device such as a head-mounted display.

The audio output device 212 outputs game audio (for example, BGM (Background Music), sound effects, voices of characters in the game, and voices of other users (other players)). The audio output device 212 also corresponds to the output interface 107 in FIG. The audio output device 212 may be a wearable audio output device (eg, earphones or headphones) or a stationary audio output device (eg, a speaker).

FIG. 3 is a flowchart of game processing. The game processing includes psychological parameter registration processing. The psychological parameter is a parameter related to the user's sensibility (tendency of change in psychological state), and indicates, for example, the strength of resistance to fear effects. The game processing in FIG. 3 is executed in the game execution device 101. For example, when a game (game program) is executed in the game execution device 101, the game processing shown in FIG. 3 starts. As described above, the game program is stored in the SSD 204 in advance, and the arithmetic unit 202 reads the program from the SSD 204, expands it to the memory 203, and executes it. From now on, the executed game will be referred to as the "target game".

In step S301, the computing device 202 determines whether the current user has played the target game for the first time (whether the target game has been executed for the first time for the current user). When the calculation device 202 determines that the current user has played the target game for the first time, the process proceeds to step S302, and when it determines that the current user has played the target game, the process proceeds to step S308. .

For example, when the user plays the target game, the computing device 202 stores the user's data (play data) in the SSD 204 . In step S301, the computing device 202 determines (confirms) whether the current user's play data is stored in the SSD 204 as the play data of the target game. If the calculation device 202 determines that the current user's play data is not stored in the SSD 204, the process proceeds to step S302, and if it determines that the current user's play data is stored in the SSD 204, the process proceeds to step S308. Proceed with the process. Note that the computing device 202 may store (upload) play data in the database 103 via the communication device 207. The computing device 202 may then determine (confirm) whether the current user's play data is stored in the database 103.

In step S302, the computing device 202 stores (registers) current user data (information) in the SSD 204 as play data of the target game. The play data includes, for example, the user's name, gender, and age.

In step S303, the computing device 202 starts (executes) a tutorial for the target game. In the tutorial, various explanations regarding the game are provided (for example, an explanation of the introduction (including an opening movie), an explanation of the screens, and an explanation of the operation method). The tutorial is executed during a predetermined period at the beginning of the game. The user wears the biological information detection device 208 before the tutorial starts. When the user wears the biological information detection device 208, the computing device 202 acquires the user's biological information from the biological information detection device 208, and estimates the user's psychological state based on the acquired biological information.

In step S304, the arithmetic device 202 stimulates the user with the effect during the tutorial (the effect included in the target game). The performance during the tutorial is, for example, a fear performance. The presentation during the tutorial may be a presentation that stimulates the user's auditory sense, a presentation that stimulates the user's visual sense, or a presentation that stimulates the user's tactile sense. It may be. The arithmetic device 202 performs calculations for effects that stimulate the sense of hearing and effects that stimulate the sense of touch. The graphics calculation device 205 performs calculations for visual stimulation in accordance with instructions from the calculation device 202.

The performance that stimulates the sense of hearing is, for example, a BGM performance, a sound effect performance, or an audio performance, and is realized by the audio output device 212. The visual stimulation effect is, for example, a lighting effect or a detail effect (graphical expression effect), and is realized by the display device 211. The effect that stimulates the tactile sense is, for example, a vibration effect, a wind effect, or an electric current effect, and is realized by the controller 209 or a device not shown.

In the BGM production, BGM is output in accordance with the game scene. For example, eerie melodies, dissonant sounds, or background music may be intentionally stopped to arouse fear in users.

In the sound effect production, sound effects are output in accordance with the game scene. For example, in order to arouse fear in the user, the sound of glass breaking or the sound of something falling may be output at a timing that catches the user by surprise.

In the audio production, the audio of characters in the game (for example, enemy characters such as ghosts and monsters) is output. For example, eerie sounds may be output to arouse fear in users, or 3D sound effects may be created that make it seem as if the sounds are being emitted right next to the user's ears.

In lighting effects, in-game lighting is controlled to match the game scene. For example, the lights may flicker, the lights may dim, or the shadow of an enemy character may appear in order to arouse fear in the user.

In detail production, details of characters in the game (for example, enemy characters) are controlled. For example, to arouse fear in the user, the enemy character's skin may be displayed in a grotesque manner, a large amount of bleeding from the enemy character may be displayed, or the enemy character's internal organs may be displayed.

In the vibration effect, vibrations are given to the user according to the game scene. For example, a vibration generator built into the controller 209 vibrates at the timing when a character operated by a user in a game falls or is attacked.

In the wind effect, wind is sent to the user according to the game scene. For example, a wind generator built into the controller 209 generates wind at the timing when a character operated by a user in a game opens a door.

In the current effect, an electric current is passed through the user in accordance with the game scene. For example, when a character operated by a user in a game is struck by lightning, an electric current is applied to the user from an electrode provided on the controller 209.

Note that the method of stimulating the user is not particularly limited, and the presentation during the tutorial may be a presentation added by the game execution device 101 (a presentation not originally included in the target game).

In step S305, the arithmetic device 202 determines (or updates) psychological parameters based on changes in the user's biometric information according to the effect (stimulation to the user) performed in step S304. As described above, the computing device 202 acquires the user's biological information from the biological information detection device 208 and estimates the user's psychological state based on the acquired biological information. The arithmetic device 202 determines (or updates) psychological parameters based on changes in the user's psychological state according to the performance performed in step S304.

For example, the user wears an electroencephalogram detection device that detects (measures) brain waves on his head as the biological information detection device 208 . The computing device 202 acquires the detection results (measurement results) of the user's brain waves from the brain wave detection device, and classifies the brain waves into θ (theta) waves, α (alpha) waves, and β (beta) waves. θ waves are brain waves in a frequency band of 4 Hz or more and less than 8 Hz, α waves are brain waves in a frequency band of 8 Hz or more and less than 13 Hz, and β waves are brain waves in a frequency band of 13 Hz or more. Generally, when humans feel nervous or fearful, their beta waves become active. Therefore, the calculation device 202 can estimate the user's fear level (the degree of fear the user feels) from the β waves.

Figure 4 shows the user's brain waves during the tutorial. The horizontal axis shows time, and the vertical axis shows voltage as brain waves. Here, the magnitude of the voltage is described as "brain wave activity level." Timing t1 is the timing at which the fear effect is performed (timing at which the process of step S304 in FIG. 3 is performed). Since the activity level of β waves has been increasing since timing t1, it can be estimated that the user is feeling fear. The calculation device 202 estimates the user's fear level according to the activity level of β waves. Then, the arithmetic device 202 stores, as a psychological parameter, the amount of change in the fear level according to the fear performance in the SSD 204.

Note that the method for estimating the fear level is not limited to the above method. For example, the calculation device 202 may estimate the fear level according to the ratio of the activity level of β waves to the activity level of θ waves or α waves. The arithmetic device 202 may estimate the fear level from at least one of theta waves, alpha waves, and beta waves using a learned model obtained by machine learning (for example, deep learning).

Furthermore, biological information is not limited to brain wave information. For example, the biological information may be information on pulse, blood pressure, blood flow, or body temperature. This information can be obtained, for example, from a detection device (measuring device) worn on the user's arm or finger. The biological information may be information on facial expressions, voice volume, or breathing (for example, breathing rate). Facial expression information and breathing information can be obtained, for example, by analyzing a user's facial image captured by a camera (not shown). The voice volume information and the breathing information can be obtained, for example, by analyzing the voice input to the microphone 210.

A plurality of pieces of information may be acquired as biometric information. The arithmetic device 202 can determine psychological parameters with higher accuracy by acquiring a plurality of pieces of information as biological information. For example, the arithmetic device 202 can determine psychological parameters that indicate more accurate sensibilities.

The arithmetic device 202 may acquire information on gender and age from the user's play data, and further use the information on the user's gender and age to determine psychological parameters. By further using information on the user's gender and age, the arithmetic device 202 can determine psychological parameters with higher accuracy.

The calculation device 202 may determine (or update) psychological parameters based on changes in biological information without estimating the psychological state.

In step S306, the arithmetic device 202 determines whether the tutorial has ended (whether all effects for determining psychological parameters have been performed). If the computing device 202 determines that the tutorial has not ended, the process returns to step S304, and if it determines that the tutorial has ended, the process advances to step S307.

In step S307, the arithmetic device 202 associates the user's psychological parameter stored in the SSD 204 in step S305 with the user's play data (play data of the target game) (psychological parameter registration). Note that the arithmetic device 202 may store in the SSD 204 a plurality of psychological parameters respectively corresponding to a plurality of performances, or may store in the SSD 204 one psychological parameter obtained by integrating the plurality of psychological parameters. Psychological parameters may be stored in the SSD 204 for each type of performance. For example, eight psychological parameters may be stored in the SSD 204, each corresponding to eight types of effects: BGM effect, sound effect effect, audio effect, lighting effect, detail effect, vibration effect, wind effect, and electric current effect. The arithmetic device 202 may store (register) psychological parameters in the database 103 via the communication device 207.

In step S308, the arithmetic device 202 performs performance control processing to control the performance of the target game based on the psychological parameters registered in step S307. The calculation device 202 does not repeat the process of determining the psychological parameters during the execution of the main part of the target game, but performs the process in advance before the main part, and uses the predetermined psychological parameters to produce the effect of the target game. Control. Thereby, it is possible to control the performance of the target game to be suitable for the user while suppressing delays in the target game. Details of the production control process will be described later using FIG. 5.

Although an example has been described in which the psychological parameters are determined and registered when the user plays the target game for the first time, the present invention is not limited to this. For example, the computing device 202 may execute predetermined content for determining psychological parameters to determine and register the psychological parameters before starting (before executing) the target game. In this case, it is not necessary to individually determine psychological parameters for each game, and common psychological parameters that can be used for each game can be determined with less effort. However, according to the game process of FIG. 3 in which psychological parameters are determined using effects included in the target game, psychological parameters more suitable for the target game can be obtained.

Further, the computing device 202 may correct (update) the psychological parameters during execution of the target game (for example, after the tutorial) based on changes in biological information according to the performance of the target game. By doing this, the amount of calculation for correcting (updating) psychological parameters is less than that for determining new psychological parameters, so it is possible to suppress delays in the target game and make the performance of the target game more suitable for the user. can be controlled.

FIG. 5 is a flowchart of the production control process (step S308 in FIG. 3).

In step S501, the computing device 202 reads the current user's psychological parameters associated with the target game from the SSD 204.

In step S502, the computing device 202 reads the performance level from the target game program stored in the SSD 204. For example, the game developer presets the degree of fear that the user (player) wants to feel as the production level of the fear production.

In step S503, the arithmetic device 202 adjusts the performance level read in step S502 based on the psychological parameter read in step S501. For example, the computing device 202 determines whether the user's fear level will fall within an appropriate range when performing a fear effect at the effect level read in step S502, based on the psychological parameters read in step S501. judge. The arithmetic unit 202 lowers the production level when determining that the user's fear level is greater than the maximum value of the appropriate range, and when determining that the user's fear level is less than the minimum value of the appropriate range. Raise your performance level. If it is determined that the user's fear level is within an appropriate range, the production level is not changed.

Various effects can be changed by changing the effect level. For example, when the BGM production level is raised, the volume of the BGM is increased, the range of the BGM is widened, and intonation is added to the BGM. When the production level is lowered, the volume of the BGM is lowered, the range of the BGM is narrowed, and the intonation of the BGM is suppressed.

Regarding sound effect production, when the production level is raised, the volume of the sound effect is increased, the range of the sound effect is expanded, and intonation is added to the sound effect. When the production level is lowered, the volume of the sound effect is lowered, the range of the sound effect is narrowed, and the intonation of the sound effect is suppressed.

Regarding audio production, when the production level is raised, the volume of the audio is increased, the range of the audio is expanded, and intonation is added to the audio. When the production level is lowered, the volume of the audio is lowered, the range of the audio is narrowed, and the intonation of the audio is suppressed.

Regarding lighting effects, when the effect level is increased, the lighting in the game is dimmed, and when the effect level is lowered, the lights are brightened. The blinking pattern of the lighting may be changed, or the degree of emphasis of the enemy character's shadow may be changed.

Regarding the detail production, when the production level is raised, the resolution of the enemy character is increased, and the amount of bleeding from the enemy character is increased. When the production level is lowered, the resolution of the enemy character is reduced, the amount of bleeding from the enemy character is reduced, and the internal organs of the enemy character are hidden.

Regarding the vibration effect, when the effect level is raised, the vibration is strengthened, and when the effect level is lowered, the vibration is weakened or set to no vibration. The vibration pattern may be changed.

Regarding the wind effect, when the effect level is raised, the wind is made stronger, and when the effect level is lowered, the wind is weakened or set so that no wind blows. The ventilation pattern may be changed.

Regarding the current effect, when the effect level is raised, the current is made stronger, and when the effect level is lowered, the current is weakened or set to not flow. The current pattern may also be changed.

Note that the calculation device 202 may read the psychological parameters (step S501), read the performance level (step S502), and adjust the performance level (step S503) for each performance or for each type of performance. You can. The calculation device 202 may read common psychological parameters and performance levels for a plurality of performances (for example, all performances), and adjust the read performance levels.

In step S504, the computing device 202 executes the effect of the target game at the effect level adjusted in step S503. As mentioned above, calculations are performed for effects that stimulate the auditory senses (e.g., BGM effects, sound effects, or audio effects) and effects that stimulate the sense of touch (e.g., vibration effects, wind effects, or electric current effects). The calculation of the performance) is performed by the calculation device 202. Calculations for visual stimulation effects (for example, lighting effects or detail effects) are performed by the graphic arithmetic unit 205 in accordance with instructions from the arithmetic unit 202 . A presentation that stimulates the sense of hearing is realized by the audio output device 212, a presentation that stimulates the sense of sight is realized by the display device 211, and a presentation that stimulates the tactile sense is realized by the controller 209 or a controller (not shown). This is realized by the device.

As described above, according to the present embodiment, the psychological parameters of the user (for example, a game player) are determined in advance, and the performance of the content (for example, a game) is controlled based on the predetermined psychological parameters. Thereby, it is possible to control the presentation of the content to be a presentation suitable for the user (a presentation that the user can enjoy) while suppressing delays in the content.

Note that the present invention may be applied to the game server 102. For example, when multiple users of multiple game execution devices connected to the network 104 play a common game, the game server 102 may determine psychological parameters individually for each of the multiple users. . Then, the game server 102 may individually control the game performance for each of the plurality of users. By doing this, multiple users can all feel and enjoy the game's presentation in the same way. Even without going through the network 104, when multiple users play a common game, psychological parameters can be determined individually for each of the multiple users, and the game performance can be individually determined for each of the multiple users. If controlled, similar effects can be achieved.
