[0009] Hereinafter, embodiments of a determination device, a determination system, and a determination method disclosed in the present application will be described in detail with reference to the accompanying drawings. Note that the present invention is not limited to the following embodiments.

[0010] First, an overview of a determination device, a determination system, and a determination method according to an embodiment will be described using FIG. 1 and FIGS. 2A to 2C. FIG. 1 is a diagram illustrating an overview of the determination system. FIGS. 2A to 2C are diagrams illustrating an overview of the determination method. Note that, although the following describes a case where the behavior to be determined for the degree of addiction is gaming, the behavior to be determined for the degree of addiction can be set arbitrarily, for example, alcohol, gambling, tobacco, drugs, smartphones, SNS (Social Network Service), etc. Furthermore, the degree of addiction can be determined by determining the addiction level indicated by a numerical value, or simply determining "yes / no" or "high / low" (in other words, a binary level determination).

[0011] 1, the determination system 1 includes a determination device 10, a biosensor 50, a server device 100, a three basic desires stimulation device 200, and a game stimulation device 300. For example, the determination system 1 may be installed in a hospital to determine the degree of addiction there, or may be a small home-installed or portable device to determine the degree of addiction in the daily life of the subject T. The determination system 1 may also be a system that connects a hospital-installed device to a portable device such as the smartphone of the subject T via a communication line such as the Internet, and exchanges necessary data to make a determination.

[0012] For example, if the determination system 1 is installed in a hospital, it is possible to determine the degree of dependence by utilizing a variety of biological signals using various testing equipment such as MRI (Magnetic Resonance Imaging), high-performance medical electroencephalographs, and CT (Computed Tomography), thereby enabling the degree of dependence to be determined more accurately.

[0013] If the determination device 10 is a portable device such as a smartphone, the degree of dependence can be determined from daily life, making it easier to determine the degree of dependence. Note that some or all of the functions of the determination device 10 may be integrated into the server device 100.

[0014] The determination device 10 is a device that determines the gaming addiction level of the subject T. For example, the determination device 10 determines the gaming addiction level of the subject T based on various biological signals input from a biological sensor 50 of the subject T. The biological sensor 50 is, for example, an electroencephalogram sensor that measures the electroencephalogram of the subject T, or various wearable devices that measure the heart rate and body temperature. As mentioned above, the biological sensor 50 may be an examination device such as an MRI.

[0015] The server device 100 is a server device that aggregates, for example, the results of the determination made by the determination device 10 regarding the gaming addiction of the subject T, the results of the biological signals, etc. That is, the server device 100 aggregates the gaming addiction level of the subject T and the biological signals associated therewith as big data. For example, the big data aggregated by the server device 100 can be used to improve the addiction level determination algorithm, etc.

[0016] The three basic needs stimulation device 200 is a device that provides stimulation related to the three basic needs of the subject T. The three basic needs here refer to one of appetite, sleep, and sex. In the following, the three basic needs will be described using appetite or sleep as an example.

[0017] For example, the three basic desires stimulation device 200 stimulates the appetite of the subject T by providing content that is reminiscent of eating, and stimulates the desire to sleep by providing content that induces sleep. Specifically, the three basic desires stimulation device 200 outputs video and audio related to eating to the subject T, releases the aroma of food, etc. Alternatively, the three basic desires stimulation device 200 may stimulate the appetite of the subject T by actually providing food.

[0018] It should be noted that the three basic desires may be stimulated by a person (stimulus provider) instead of the three basic desires stimulation device 200. In this case, the three basic desires stimulation device 200 performs an operation of informing the stimulus provider that the three basic desires stimulation will be provided, and outputting a signal (based on a stimulus provision completion input by the stimulus provider) to the determination device 10 indicating that the three basic desires stimulation has been provided (start / end information).

[0019] The gaming stimulation device 300 is a device that provides gaming-related stimulation to the subject T. For example, the gaming stimulation device 300 stimulates the gaming desire of the subject T by providing the subject T with sounds, videos, etc. used in the game. The gaming stimulation device 300 may be the game console itself, images of a game match, etc. Furthermore, when the game to be determined as the addiction level is a game app on a smartphone, the smartphone may be regarded as the gaming stimulation device 300. As with the above-described three basic desires stimulation device 200, a person may provide gaming-related stimulation instead of the gaming stimulation device 300 (for example, by showing the game console to the subject T or playing the game in front of the subject T).

[0020] Next, an overview of the assessment method according to the embodiment will be described with reference to Fig. 2. In the assessment method according to the embodiment, the degree of addiction is determined from the pleasure level of an addiction-level assessment target behavior (for example, gaming) using the pleasure level of the subject T with respect to the three basic needs as a reference. That is, in the assessment method according to the embodiment, the degree of addiction to an addiction-level assessment target behavior is determined by comparing the three basic needs possessed by all subjects T with the addiction-level assessment target behavioral needs. Note that there are various types of behaviors that can be used for dependency-level assessment, but for ease of explanation, gaming will be used as a representative example of an addiction-level assessment target behavior.

[0021] Specifically, as shown in FIG. 2A, when a stimulus for one of the three basic desires is generated for the subject T (step S1), the biological signals are analyzed (step S2), and the pleasure levels for the three basic desires are calculated (step S3).

[0022] For example, in steps S2 and S3, the pleasure level for the three basic needs is calculated from the biological signals of the subject T when his / her appetite is stimulated. To give a more specific example, the pleasure level for appetite or sleepiness is calculated from the biological signals when the subject T eats a meal while hungry, or when the subject T is allowed to sleep while sleepy.

[0023] That is, in the determination method according to the embodiment, the pleasure level for the three basic needs is calculated from the biological signals when the subject T satisfies the three basic needs.

[0024] Although these methods calculate the degree of pleasure from the reaction when the desire is satisfied, it is believed that the reaction when the desire arises but before the desire is satisfied, that is, the reaction of the subject when the subject is made aware of the desire, correlates with the degree of pleasure when the desire is satisfied. Therefore, it is also possible to estimate (calculate) the degree of pleasure based on the biological reaction of subject T when he is made aware of the desire.

[0025] Furthermore, in the determination method according to the embodiment, the biological signals of the subject T when the desire to play a game is stimulated and generated in the subject T (step S4) are analyzed (step S5), and the pleasure level for the game is calculated (step S6). To give a more specific example, the pleasure level for the game is calculated from the biological signals when the subject T plays a game of his / her own volition, or when the subject T requests to play a game and is allowed to play the game.

[0026] As with the three basic needs mentioned above, it is also possible to estimate (calculate) the degree of pleasure from a game based on the subject's biological reactions when the subject is made aware of their desire to play games.Specifically, for example, the desire to play games can be stimulated by providing subject T with music and images used in the game, and the degree of pleasure from the game can be calculated from the biological signals at that time.

[0027] Then, in the determination method according to the embodiment, the degree of addiction to games is determined from the pleasure level for the games calculated in step S6, using the pleasure level for the three basic human needs calculated in step S3 as a reference (step S7).

[0028] For example, in the assessment method according to the embodiment, the greater the pleasure level from games compared to the pleasure level from the three basic needs, the higher the degree of gaming addiction is determined to be. In other words, the degree of gaming addiction is assessed based on the relative relationship (the difference in magnitude, ratio, etc.) between the pleasure level from the three basic needs and the pleasure level from games (absolute pleasure levels may also be taken into consideration).

[0029] Furthermore, the pleasure levels used in the assessment can be appropriately selected and processed, such as by using measurements taken over an appropriate period to eliminate noise or depending on the purpose and method of use of the assessment, or by using values ​​that have been subjected to appropriate statistical processing (average, etc.).

[0030] In this way, the assessment method according to the embodiment can accurately assess the degree of addiction to games by determining the degree of enjoyment of the games based on the enjoyment of the three basic needs. Furthermore, the assessment method according to the embodiment assesses the degree of addiction using a biosignal input from the biosensor 50. This allows for a more accurate understanding of the state of the brain than when assessing the degree of addiction through counseling or the like, thereby enabling the degree of addiction to be assessed with high accuracy.

[0031] Next, we will explain a derivative method of the assessment method. The assessment method shown in Figure 2B is a method for assessing the level of gaming addiction based on changes in pleasure level when a gaming desire stimulus is given while the person is performing an action corresponding to one of the three basic needs. In other words, this method of assessing gaming addiction is based on the idea that if the level of gaming addiction is high, the impact of gaming desire stimulus on pleasure level (biological signals) while the person is performing an action corresponding to one of the three basic needs will be greater, resulting in larger changes in pleasure level (biological signals).

[0032] Specifically, as shown in Fig. 2B, the biological signals of the subject T while he / she is engaging in one of the three basic needs activities (e.g., while eating) are analyzed (step S12), and the pleasure levels for each of the three basic needs are continuously calculated (step S13). Note that the determination of whether or not the subject T is eating can be made by manual input by the subject T or the person conducting the test, or by other methods such as analysis of camera images or biological signals of the subject.

[0033] Next, subject T's desire to play games is stimulated while he is performing the three basic needs, and trigger information (start and end times) of the stimulation is acquired (step S14). Then, the degree of addiction to games is determined based on the change in pleasure level for the three basic needs during subject T's three basic needs behavior (the difference or ratio between the pleasure level when the game desire stimulation is present and the pleasure level when the game desire stimulation is not present, etc.) (step S15).

[0034] The assessment method shown in Figure 2C is a method for assessing the degree of gaming addiction based on changes in pleasure level when the three basic needs are stimulated while playing a game. In other words, this method is based on the idea that if the degree of gaming addiction is high, the impact of the three basic needs stimulation on pleasure level (biological signals) while playing a game is small, and changes in pleasure level (biological signals) are inferred to be small.

[0035] Specifically, as shown in Fig. 2C, the biological signals of the subject T while he / she is playing the game are analyzed (step S22), and the pleasure level for playing the game is continuously calculated (step S23). The judgment during game playing can be made by manual input by the subject T or the test executor, or it can also be made by other methods such as analyzing camera images or biological signals of the subject, or detecting action signals from the game console.

[0036] Next, the three basic desires of subject T are stimulated while subject T is playing the game, and trigger information (start and end times) of the stimulation is acquired (step S24). Then, the degree of addiction to the game is determined based on the change in pleasure level from the game while subject T is playing the game (the difference or ratio between the pleasure level when the three basic desires are stimulated and the pleasure level when the three basic desires are not stimulated, etc.) (step S25).

[0037] Next, a configuration example of the determination device 10 according to the embodiment will be described with reference to Fig. 3. Fig. 3 is a block diagram of the determination device 10. As shown in Fig. 3, the determination device 10 according to the embodiment has a communication unit 110, a control unit 120, and a storage unit 130. Note that the determination method shown in Fig. 2A will be mainly described, but Figs. 2B and 2C also have substantially the same configuration.

[0038] The communication unit 110 is a communication module for performing data communication with the biosensor 50 and the server device 100 (see FIG. 1) via a predetermined network.

[0039] The storage unit 130 is realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory, or a storage device such as a hard disk or an optical disk. In the example of FIG. 3, the storage unit 130 has a pleasure level information storage unit 131 and a dependency level information storage unit 132.

[0040] The pleasure intensity information storage unit 131 stores information related to the behavioral history of the subject T. Fig. 4 is a diagram showing an example of the pleasure intensity information storage unit 131. In the example of Fig. 4, the pleasure intensity information storage unit 131 stores information on items such as "date and time," "action," and "pleasure intensity" in association with one another.

[0041] "Date and time" indicates the date and time when subject T performed the corresponding action (including the three basic needs-meeting behavior and the behavior subject to dependency assessment). "Action" indicates the action performed by subject T at the corresponding date and time. Examples of actions may include, for example, behaviors related to gaming, eating, sleeping, exercise, etc. The behavioral history stored in the pleasure level information storage unit 131 may be estimated or acquired, for example, in conjunction with a healthcare app on a smartphone or the like, or may be estimated from subject T's heart rate data, etc. Regarding actions, it is considered realistic to use data manually input by subject T or the like into a smartphone or the like, or to apply smartphone calendar data (scheduled date and content), taking into account accuracy, etc.

[0042] Then, from this stored data, data is extracted by stratification by action and range by date and time, and the pleasure levels are statistically processed (averaged, etc.) to calculate the pleasure levels for addiction assessment. For example, the pleasure levels of the action "gaming" over the past week are extracted and averaged to calculate a "gaming pleasure level" for addiction assessment, and the pleasure levels of the action "eating (appetite)" over the past week are extracted and averaged to calculate an "appetite pleasure level" for addiction assessment, and these "gaming pleasure levels" and "appetite pleasure levels" are used to assess the current level of gaming addiction (based on data from the past week).

[0043] Returning to the explanation of Fig. 3, the dependency information storage unit 132 will be described. The dependency information storage unit 132 is a storage unit that stores various information related to the dependency of the subject T. Fig. 5 is a diagram showing an example of the dependency information storage unit 132.

[0044] As shown in FIG. 5, the dependency information storage unit 132 stores information on items such as "date and time," "pleasure level of three basic desires," "pleasure level of desire for games," "game dependency," and "determination conditions" in association with one another.

[0045] "Date and time" indicates the date and time when the corresponding addiction level was judged. "Basic needs pleasure level" indicates the pleasure level of subject T for the three basic needs judged on the corresponding date and time. "Game desire pleasure level" indicates the pleasure level of subject T for games judged on the corresponding date and time.

[0046] Furthermore, "Gaming Addiction Level" indicates the gaming addiction level of subject T determined at the corresponding date and time. "Determination Condition" stores data such as the conditions and circumstances under which the determination was made, for example, the period of collection of bio-information for which the three basic desire pleasure levels and gaming desire pleasure levels were calculated (for example, data collected over the past week). In addition, the addiction information storage unit 132 may store information on items such as the bio-signal of the bio-sensor 50, the craving level (described later), and the type of stimulation, in association with each other.

[0047] Returning to the explanation of Fig. 3, the control unit 120 will be described. The control unit 120 is a controller, and is realized by, for example, a CPU (Central Processing Unit) or an MPU (Micro Processing Unit) executing various programs (not shown) stored in the storage unit 130 using RAM as a work area. The control unit 120 can also be realized by, for example, an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

[0048] In the example shown in FIG. 3, the control unit 120 includes a biological signal acquisition unit 121, a craving level estimation unit 122, a biological signal analysis unit 123, a pleasure level calculation unit 124, a dependence level determination unit 125, and a determination result output unit 126.

[0049] The biological signal acquisition unit 121 acquires the biological signal of each subject T when, for example, the three basic desires stimulation device 200 or the game stimulation device 300 stimulates the three basic desires or the desire to play games to the subject T.

[0050] The trigger for generating a stimulus by the three major desires stimulation device 200 or the game stimulation device 300 may be an instruction from the determination device 10, or may be generated spontaneously by the three major desires stimulation device 200 or the game stimulation device 300.

[0051] The determination device 10 (control unit 120) may determine whether or not there is a stimulation related to the three basic needs based on changes in biological signals, etc. For example, it may determine that the three basic needs (or their stimulation) are occurring naturally based on biological signals indicating hunger or sleepiness, or the time elapsed since the last meal or sleep (estimated from data such as a schedule registered in the mobile device of the subject T or a biological signal history). In this case, the determination device 10 can calculate the three basic needs pleasure level even without the three basic needs stimulation device 200.

[0052] The craving degree estimation unit 122 estimates the three basic desires or the degree of desire of the subject T for games. Here, the craving degree is an index indicating how much the subject T desires something. For example, the craving degree estimation unit 122 estimates the current level of sleepiness or current hunger as the degree of desire for the three basic desires (hereinafter referred to as the three basic desire craving degrees).

[0053] For example, the thirst level estimation unit 122 estimates drowsiness from biosignals (heart rate, electroencephalogram) and the behavioral history of the subject T (for example, sleep history, activity history). Additionally, the thirst level estimation unit 122 estimates hunger as a measure of appetite craving. Specifically, the hunger level is estimated from the acetone concentration contained in the breath of the subject T or the subject's dietary history. It is generally known that the acetone concentration contained in the breath of a person when hungry is higher than when full. Based on this knowledge, the thirst level estimation unit 122 estimates the hunger level from the acetone concentration. In this case, the biosignal acquisition unit 121 acquires information related to the acetone concentration contained in the breath of the subject T as a biosignal from an acetone concentration sensor (worn by the subject T), and passes the information related to the acetone concentration to the thirst level estimation unit 122.

[0054] The desire level estimation unit 122 also estimates the desire level for a game (game desire level) from the game play history. For example, the desire level estimation unit 122 estimates the desire level for the current game based on the game play history, using parameters such as play time (e.g., elapsed time since the previous game play), play frequency, etc.

[0055] The craving degree estimation unit 122 passes information relating to the estimated craving degree for the three basic needs and craving degree for games to the dependency determination unit 125. When the occurrence of stimulation of the three basic needs (or the occurrence of the three basic needs) is estimated based on biological signals, the craving degree and the occurrence of stimulation of the three basic needs can be said to have the same meaning, but by changing the determination threshold or by using data with level or step characteristics for the craving degree, the craving degree can have the effect of improving the accuracy of dependency determination.

[0056] The biological signal analysis unit 123 analyzes the biological signal received from the biological signal acquisition unit 121. For example, the biological signal analysis unit 123 extracts a feature quantity related to the pleasure level from the biological signal and passes the extracted feature quantity related to the pleasure level to the pleasure level calculation unit 124. The feature quantity related to the pleasure level here may include, for example, a parameter related to the sympathetic nerves, a parameter related to the arousal level, etc.

[0057] The pleasure degree calculation unit 124 calculates the pleasure degree for the three basic desires and the pleasure degree for the game based on the biological signals. For example, the pleasure degree calculation unit 124 calculates the pleasure degree from the pattern of changes and the amount of change based on the feature amounts related to the pleasure degrees received from the biological signal analysis unit 123.

[0058] Fig. 6 is a schematic diagram of calculation parameters for pleasure level. For example, as shown in Fig. 6, the pleasure level calculation unit 124 calculates pleasure level using a three-axis calculation map (four axes if time changes are taken into account) in which the vertical axis represents the parameter value of arousal level, the horizontal axis represents the parameter value of sympathetic nerve activity, and the depth axis represents the solution for pleasure level. In other words, the pleasure level is determined by the arousal level and the sympathetic nerve activity level. Specifically, a table is formed in which the pleasure level is stored in cells (memory addresses) indicated by the arousal level and the sympathetic nerve activity level, and the pleasure level is found by reading the value of the cell determined by the detected arousal level and sympathetic nerve activity level.

[0059] The arousal level indicates the arousal level of the brain, i.e., the degree to which the subject T is aroused. The sympathetic nerve activity level indicates the degree to which the sympathetic nerves in the brain are activated. For example, the pleasure level calculation unit 124 calculates the three basic desires pleasure level or the game pleasure level by determining a corresponding point on the map shown in FIG. 6 using the arousal level and sympathetic nerve activity level, which are feature quantities related to pleasure levels received from the biological signal analysis unit 123, and reading the pleasure level at that point. The pleasure level calculation unit 124 also passes information related to the calculated three basic desires pleasure level and game pleasure level to the dependence level determination unit 125.

[0060] 3, the dependency determination unit 125 will be described. The dependency determination unit 125 determines the degree of game addiction from the game pleasure level, using the three basic needs pleasure levels calculated by the pleasure level calculation unit 124 as a reference.

[0061] For example, the addiction determination unit 125 determines the degree of game addiction by comparing the degree of pleasure of the three basic needs with the degree of pleasure from games. Specifically, the addiction determination unit 125 determines the degree of game addiction as a relative value, such as a difference or ratio between the degree of pleasure from the three basic needs and the degree of pleasure from games.

[0062] In addition, a model showing the relationship between the pleasure level of the three basic needs, the pleasure level of gaming, and the degree of gaming addiction may be generated by machine learning using big data accumulated in the server device 100, and the addiction determination unit 125 may use this model to calculate the degree of gaming addiction from the pleasure level of the three basic needs and the pleasure level of gaming.

[0063] Furthermore, the addiction determination unit 125 may calculate the degree of game addiction using as parameters the degree of desire for the three basic desires and the degree of desire for games estimated by the desire degree estimation unit 122. In this case, for example, the addiction determination unit 125 calculates the degree of game addiction using the degree of pleasure for the three basic desires and the degree of desire for games when the degree of desire for the three basic desires and the degree of desire for games are at the same level. Alternatively, the addiction determination unit 125 corrects the degree of pleasure for the three basic desires and the degree of desire for games using the degree of desire for the three basic desires and the degree of desire for games, and calculates the degree of game addiction as the corrected value of the degree of pleasure for the three basic desires and the degree of desire for games when the degree of desire for the three basic desires and the degree of desire for games are at the same level.

[0064] In other words, the pleasure level of a certain action has the characteristic of changing depending on the level of desire for that action at the time. For example, the pleasure level of eating is high when hungry (high desire) and low when full (high desire). Therefore, when calculating game addiction, a correction process is performed to match the conditions of desire level.

[0065] In this way, by adding both cravings to the parameters, it is possible to determine the degree of gaming addiction while combining the conditions of the three basic needs pleasure level and the gaming pleasure desire pleasure level, thereby improving the accuracy of calculating the degree of gaming addiction.

[0066] The addiction assessment unit 125 may calculate the degree of gaming addiction after correcting the degree of pleasure of the three basic needs according to the degree of craving for the three basic needs, and further correcting the degree of desire for gaming according to the degree of desire for gaming, or after correcting the degree of pleasure of the three basic needs or the degree of desire for gaming pleasure according to the difference between the degree of craving for the three basic needs and the degree of desire for gaming. The addiction assessment unit 125 stores the determined degree of gaming addiction in the addiction information storage unit 132 together with the date and time.

[0067] The determination result output unit 126 outputs the determination result of the dependency determination unit 125. For example, the determination result output unit 126 outputs the determination result to a terminal device (for example, a smartphone) of the subject T.

[0068] FIG. 7 is a diagram showing an example of a notification screen of the assessment result. The example of FIG. 7 shows a notification screen of the assessment result including a graph with the vertical axis representing the degree of addiction (game addiction) and the horizontal axis representing the date and time. In the example of FIG. 7, the degree of addiction decreases over time, and the notification screen includes a comment such as "Just one more push!". In the example of FIG. 7, the display (notification) screen is generated by processing the data of the gaming addiction stored in the addiction information storage unit 132 (selecting data for the target period and arranging it in chronological order). This example is not limiting; various notification screens can be generated by processing, statistically processing, etc., the data of various addictions stored in the addiction information storage unit 132.

[0069] By providing such a notification screen to the subject T, the subject T can easily understand the transition in the degree of dependency.

[0070] Furthermore, the determination result output unit 126 may cooperate with a game machine and perform various controls related to improving the degree of addiction, such as restricting or prohibiting game use, depending on the determination result.

[0071] Next, a configuration example of the server device 100 according to the embodiment will be described with reference to Fig. 8. Fig. 8 is a block diagram of the server device 100. As shown in Fig. 8, the server device 100 includes a communication unit 141, a control unit 142, and a storage unit 143.

[0072] The communication unit 141 is a communication module for performing data communication with the determination device 10 via a predetermined network.

[0073] The storage unit 143 is realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory, or a storage device such as a hard disk or an optical disk.

[0074] For example, the storage unit 143 stores, as big data, various types of information related to the degree of dependence collected from each determination device 10. In addition, for example, the storage unit 143 stores information related to the diagnosis results (for example, medical records) of the subject T from a doctor.

[0075] The control unit 142 is a controller, and is realized, for example, by a CPU (Central Processing Unit) or an MPU (Micro Processing Unit) executing various programs (not shown) stored in the storage unit 143 using a RAM as a work area. The control unit 142 can also be realized, for example, by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

[0076] The control unit 142 generates a model that learns the relationship between the three basic desire pleasure levels, the gaming desire pleasure level, and the addiction level by performing machine learning using, for example, the medical records of each subject T as training data and the judgment results by the judgment device 10 as learning data. For example, such a model is distributed to each judgment device 10, and each judgment device 10 uses such a model to judge the addiction level.

[0077] Furthermore, for example, the control unit 142 may generate a model showing the relationship between the transition of the dependency level and the behavior taken by the subject T, for example, by machine learning using information on the transition of the dependency level and information on the behavioral history of the subject T. Such a model is, for example, a model for identifying the behavior taken by the subject T whose dependency level has improved and the behavior not taken by the subject T. For example, by using such a model, it becomes possible to provide various kinds of advice regarding the improvement of the dependency level.

[0078] In the above example, AI (artificial intelligence) is used to make judgments and give advice, but it can also be used to estimate the tendency of subject T's dependency level, the relationship between subject T's behavior and changes in dependency level, etc. through various statistical processing, and provide the results to subject T or a counselor, etc. to be used for treatment, etc.

[0079] Next, the processing procedure executed by the determination device 10 according to the embodiment will be described with reference to Fig. 9 to Fig. 12. Fig. 9 to Fig. 12 are flowcharts showing the processing procedure executed by the determination device 10, and the processing shown in Fig. 10 represents a process for making a determination using the desire level data as well. Note that these processes are repeatedly executed during the operation of the determination device 10.

[0080] First, as shown in FIG. 9, the judgment device 10 (control unit 120) judges whether it is time to calculate the pleasure level of the three basic desires (step S101), and if it judges that it is time to do so (step S101; Yes), it issues a command to issue a three basic desires stimulus (step S102), and if it judges that it is not time to do so (step S101; No), it proceeds to processing in step S105.

[0081] By this process, for example, when the tester performs an operation to start calculating the pleasure level of the three basic desires, a drive start signal is output to the three basic desires stimulation device 200, and a guidance message is displayed to the tester instructing him / her to stimulate the three basic desires of the subject.

[0082] Next, the determination device 10 acquires a biological signal when the three basic desires are stimulated (step S103), and calculates the three basic desire pleasure levels (step S104). Next, the determination device 10 determines whether it is time to calculate the gaming desire pleasure level (step S105), and if it determines that it is time to do so (step S105; Yes), it issues an instruction to issue a gaming stimulus (step S106). Furthermore, if the determination device 10 determines in the determination of step S105 that it is not time to calculate the gaming desire pleasure level (step S105; No), it proceeds to the processing of step S109.

[0083] By this process, for example, if the test executor performs an operation to start calculating the gaming desire pleasure level, a drive start signal will be output to the gaming stimulation device 300, and a guidance display will be displayed to the test executor to give the test subject a gaming stimulation.

[0084] Next, the determination device 10 acquires a biological signal when the gaming desire is stimulated (step S107), and calculates the gaming desire pleasure level (step S108). Subsequently, the determination device 10 determines whether it is time to determine the gaming addiction level (step S109).

[0085] If it is time to determine the degree of gaming addiction (step S109; Yes), the determination device 10 determines the degree of gaming addiction based on the calculated (stored) three basic needs pleasure level and the gaming desire pleasure level (step S110), and ends the process. On the other hand, if the determination device 10 determines that it is not time to determine the degree of gaming addiction (step S109; No), it ends the process.

[0086] Next, an example of a process for determining the degree of game addiction that takes into account the degree of craving will be described with reference to Fig. 10. As shown in Fig. 10, the determination device 10 (control unit 120) determines whether it is time to calculate the degree of pleasure of the three basic desires (step S111). If it is (step S111; Yes), it issues a command to stimulate the three basic desires (step S112). If it is not (step S111; No), it proceeds to the process of step S115. Next, the determination device 10 estimates the degree of craving for the three basic desires (step S113), and acquires a biological signal when the three basic desires are stimulated to calculate the degree of pleasure of the three basic desires (step S114).

[0087] Next, the determination device 10 determines whether it is time to determine the degree of game addiction (step S115). If it is time to determine the degree of game addiction (step S115; Yes), the determination device 10 estimates the degree of game craving (step S116) and determines whether the estimated degree of game craving is similar to the degree of three basic desires craving (the degree of three basic desires craving estimated in step S113) (step S117).

[0088] If the determination device 10 determines that the game desire degree and the three basic desire desire degree are at the same level (step S117; Yes), the process proceeds to step S118, and if it determines that the game desire degree and the three basic desire desire degree are not at the same level (step S117; No), for example, if the three basic desire desire degree is greater than the game desire degree, the process proceeds to step S116. In other words, these processes are wait processes when calculating the three basic desire desire degree and the game desire hedonic degree, until the game desire degree and the three basic desire desire degree become approximately the same.

[0089] Next, the determination device 10 issues a command to generate a game stimulus (step S118), and proceeds to the processing of step S119. The determination device 10 acquires a biological signal and calculates a game desire pleasure level (step S119). Then, the determination device 10 determines the game addiction level from the game desire pleasure level based on the three basic desire pleasure levels (step S120), and ends the processing.

[0090] In the process of FIG. 10, the determination device 10 determines the degree of game addiction based on the three basic needs pleasure level and the game desire pleasure level under the condition that the game desire level and the three basic needs desire level are the same. As described above, the determination device 10 may correct the three basic desires pleasure degree and the desire for games pleasure degree in accordance with the three basic desires craving degree and the desire for games craving degree, and then determine the degree of game addiction based on the corrected three basic desires pleasure degree and the desire for games craving degree. In this case, in the process shown in Figure 10, except for the process of step S115, a process of "correcting the three basic desires pleasure degree and the desire for games pleasure degree based on the three basic desires craving degree and the desire for games craving degree, respectively" is added before step S118.

[0091] Next, a specific processing method of the determination method shown in Fig. 2B will be described with reference to the flowchart of Fig. 11. Note that these processes are repeatedly executed during the operation of the determination device 10.

[0092] The determination device 10 (control unit 120) determines whether there is a request to determine the degree of game addiction based on the input operation of the test executor, etc. (step S201). If there is a request (step S201; Yes), the process proceeds to step S202; if there is no request (step S201; No), the process ends.

[0093] Next, the judgment device 10 (control unit 120) determines whether the subject T is currently performing one of the three basic desire actions, for example, whether he or she is eating (step S202). If the subject T is currently performing one of the three basic desire actions (step S202; Yes), the process proceeds to step S203; if the subject T is not currently performing one of the three basic desire actions (step S202; No), the process ends.

[0094] If the player is not currently performing the three basic needs behavior, it is effective to provide a guide (display, etc.) to encourage the player to perform the three basic needs behavior in order to facilitate the determination of the game addiction level. Then, in step S203, the determination device 10 acquires biometric information, calculates the three basic needs pleasure level based on the biometric information, and starts the operation of recording it.

[0095] Although not shown in the flowchart, the pleasure levels of the three basic needs are calculated and recorded over a predetermined time (a period during which the amount of data required to determine the degree of gaming addiction can be collected) (after the predetermined time has elapsed, the process proceeds to step S204). During steps S203 and S204, the pleasure levels of the three basic needs in a state without game stimulation while the three basic needs behaviors are being performed are calculated and recorded sequentially.

[0096] Next, in step S204, the determination device 10 issues a command to start applying game stimuli to the subject, and after a predetermined time (a time period during which the amount of data required to determine the degree of game addiction can be collected), issues a command to end the application of game stimuli to the subject.

[0097] Through these processes, the pleasure levels of the three basic needs in the state with game stimulation while the three basic needs behavior is being performed are sequentially calculated and recorded during the period from step S204 to step S205. Then, the determination device 10 determines the degree of game addiction based on the data of the pleasure levels of the three basic needs in the state with and without game stimulation while the three basic needs behavior is being performed, for example, based on the difference or ratio between the average pleasure levels of the three basic needs in the state with and without game stimulation, or the transition of the pleasure levels of the three basic needs (step S206).

[0098] By the above-described processing, it is possible to determine the degree of gaming addiction based on the change in pleasure level when a gaming desire stimulus is given while the player is performing an action corresponding to one of the three basic needs.

[0099] Next, a specific processing method of the determination method shown in Fig. 2C will be described with reference to the flowchart of Fig. 12. Note that these processes are repeatedly executed during the operation of the determination device 10.

[0100] The determination device 10 (control unit 120) determines whether there is a request to determine the degree of game addiction based on the input operation of the test executor, etc. (step S301). If there is a request (step S301; Yes), the process proceeds to step S302; if there is no request (step S301; No), the process ends.

[0101] Next, the determination device 10 (control unit 120) determines whether the subject T is playing a game (step S302), and if the subject T is playing a game (step S302; Yes), the process proceeds to step S303, and if the subject T is not playing a game (step S302; No), the process ends. If the subject T is not playing a game, it is effective to provide guidance (such as a display) to encourage the subject to start playing a game in order to facilitate the determination of the degree of gaming addiction.

[0102] Then, in step S303, the determination device 10 acquires biometric information, calculates a gaming desire pleasure level based on the biometric information, and starts recording the operation. Although not shown in the flowchart, the gaming desire pleasure level is calculated and recorded over a predetermined time (a time period during which the amount of data required for determining the degree of gaming addiction can be collected) (after the predetermined time period, the process proceeds to step S304). During the period from step S303 to step S304, the gaming desire pleasure level in a state in which the three major desires are not stimulated during game play is sequentially calculated and recorded.

[0103] Next, in step S304, the determination device 10 issues a command to start applying the three basic desires stimulation to the subject, and then issues a command to end the application of the three basic desires stimulation to the subject after a predetermined time (a time period during which the amount of data required for determining the degree of game addiction can be collected). Through these processes, the pleasure levels of the three basic desires in the state in which the three basic desires are stimulated during game play are sequentially calculated and recorded during the period from step S304 to step S305.

[0104] The determination device 10 then determines the degree of game addiction based on the data on the pleasure levels of the three basic desires in the state where the three basic desires are not stimulated and in the state where the three basic desires are stimulated during game play, for example, based on the difference or ratio between the average pleasure levels of game desire in the state where the three basic desires are not stimulated and in the state where the three basic desires are stimulated, or on the transition of the pleasure levels of game desire (step S306).

[0105] By the above-described processing, it is possible to determine the degree of gaming addiction based on the change in pleasure level when a gaming desire stimulus is given while the player is performing an action corresponding to one of the three basic needs.

[0106] As described above, the determination device 10 according to the embodiment is a determination device that determines the degree of dependence on the behavior to be determined, and includes the control unit 120. The control unit 120 determines the degree of dependence on the behavior to be determined based on biological responses to three basic desire stimuli that are stimuli related to the three basic desires and a determination target desire stimulus that is a stimulus related to the behavior to be determined. Therefore, the determination device 10 according to the embodiment can accurately determine the degree of dependence.

[0107] In the above-described embodiment, the behavior to be determined is gaming, and the gaming addiction level is determined. However, the present invention is not limited to this and may be changed as desired. Furthermore, the behavior to be determined may itself be one of the three basic needs. In this case, for example, the addiction level of the need for sleep or sex may be determined based on appetite.

[0108] Further advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
