Description

  The present invention relates to an information presentation system, a program, an information storage medium, and the like.

  In the so-called ubiquitous service, as one direction that is currently aimed at, a convenience providing service is proposed in which necessary information is provided to users anytime and anywhere. This is a service that unilaterally provides information to the user from the outside.

  However, in order for a person to live a lively and fulfilling life, a convenience-providing service that provides information to the user unilaterally from the outside is not sufficient. Inspire-type ubiquitous services that encourage awareness and encourage self-growth are desired.

  However, conventional information presentation systems have a problem that information presentation as so-called push information, in which information required by the user is provided without the user performing an intentional acquisition action, cannot be realized.

  As a solution to such a problem, an information presentation system disclosed in Patent Document 1 is known. In this system, it is possible to present information as push information by estimating a user's action by a wearable sensor and displaying information according to the action.

  However, in Patent Document 1, information whose necessity is manifested is presented to the user as push information without operation, which is convenient but only supports the extension of daily life patterns. It is difficult for new awareness to be born only from the standardized life and behavior, and it does not lead to a fulfilling life. Therefore, it is not possible to support actions or the like ahead of new awareness. On the other hand, when the information presented for the user's action support is information that is difficult to expect for the user or information that recommends action support that is actually unnecessary for the user, depending on the user, There may be anxiety or discomfort with the presentation system.

  The portable electronic device 100 (mobile computer) is a portable information terminal such as a PDA (Personal Digital Assistant) or a notebook PC. For example, a processor (CPU), a memory, an operation panel, a communication device, a display (sub-display), or the like. Is provided. The portable electronic device 100 has, for example, a function of collecting sensor information from sensors, a function of performing arithmetic processing based on the collected sensor information, and control (display control) of a control target device (such as a wearable display) based on a calculation result. Etc.), a function of retrieving information from an external database, a function of communicating with the outside, and the like. The portable electronic device 100 may be a device that is also used as a mobile phone, a wristwatch, a portable audio, or the like.

  The wearable display 140 (information presentation unit in a broad sense) is mounted in the vicinity of one eye of the user and is set so that the size of the display unit is smaller than the size of the pupil. Function as. Information presentation to the user may be performed using headphones, a vibrator, or the like. In addition to the wearable display 140, various devices such as a wristwatch, a mobile phone, or a portable audio can be assumed as the mobile control target device (information presentation unit).

  The indoor / outdoor sensor 510 is a sensor that detects whether the user is indoors or outdoors. For example, the user irradiates ultrasonic waves and measures the time until the ultrasonic waves are reflected back from the ceiling or the like. However, the indoor / outdoor sensor 510 is not limited to the ultrasonic method, and may be an active light method, passive ultraviolet method, passive infrared method, or passive noise method sensor.

  The ambient temperature sensor 511 measures the ambient temperature using, for example, a thermistor, a radiation thermometer, a thermocouple, or the like. The ambient humidity sensor 512 measures the ambient humidity using, for example, the change in electrical resistance due to humidity. The ambient light intensity sensor 513 measures the ambient light intensity using, for example, a photoelectric element.

The arm-mounted motion measurement sensor 520 measures the movement of the user's arm with an acceleration sensor or an angular acceleration sensor. By using the motion measurement sensor 520 and the foot pressure sensor 530, it is possible to more accurately measure the user's daily motion and walking state. The pulse (heart rate) sensor 521 is attached to the wrist, finger, or ear, and measures, for example, changes in blood flow associated with pulsation by changes in infrared light transmittance and reflectance. The body temperature sensor 522 and the peripheral skin temperature sensor 523 measure the user's body temperature and peripheral skin temperature using a thermistor, a radiation thermometer, a thermocouple, and the like. The perspiration sensor 524 measures the perspiration of the skin based on, for example, a change in the surface resistance of the skin.

The pupil size sensor 561, for example, places a camera near the pupil and analyzes the camera signal to measure the size of the pupil.

2. First System Configuration Example FIG. 2 shows a first system configuration example of the information processing system (information presentation system) of this embodiment. FIG. 2 shows an example in which the information processing system of the present embodiment is realized by the portable electronic device 100, for example.

  The processing unit 102 performs various processes based on operation information from the operation unit 160, sensor information acquired from the wearable sensor 150, and the like. The function of the processing unit 102 can be realized by hardware such as various processors (CPU, etc.), ASIC (gate array, etc.), a program stored in the information storage medium 130 (optical disc, IC card, HDD, etc.), and the like.

  The processing unit 102 includes an information acquisition unit 104, a situation estimation unit 106, a base content selection unit 108, a presentation permitted content selection unit 110, a theme registration processing unit 112, a presentation control unit 114, an interest level evaluation unit 116, and an achievement level evaluation unit 118. including. Note that various modifications such as omitting some of these components (for example, the information acquisition unit and the situation estimation unit) and adding other components are possible.

  The information acquisition unit 104 acquires sensor information and the like from the wearable sensor 150 (sensor in a broad sense). Specifically, the wearable sensor 150 is a behavior sensor that measures user behavior (walking, conversation, meal, limb movement, emotional expression, sleep, etc.), user status (fatigue, tension, hunger, mental status, body An information acquisition unit including at least one of a state sensor for measuring a state or an event generated by the user and an environment sensor for measuring a user environment (location, time, brightness, temperature, humidity, etc.) 104 acquires sensor information from these sensors.

  The sensor may be the sensor device itself, or may be a sensor device including a control unit, a communication unit, and the like in addition to the sensor device. The sensor information may be sensor primary information obtained directly from the sensor, or sensor secondary information obtained by processing (information processing) the sensor primary information.

  The information acquisition unit 104 can also acquire user operation information from the operation unit 160, external information acquired via the communication unit 138 and the like, and user schedule information stored in the storage unit 120.

  The situation estimation unit 106 (situation identification unit) estimates (identifies) a user situation (at least one of the user's behavior, state, and environment) based on the sensor information acquired by the information acquisition unit 104. Process. Specifically, multiplication processing or addition processing of the acquired sensor information is performed to realize various calculation processing for sensor information filtering processing (selection processing) or analysis processing. And the situation identification process which is a process which estimates a user's present condition is performed. Alternatively, a situation prediction process that is a process for estimating the future situation of the user is performed. The situation estimation unit 106 may store history information that stores the estimated user situation in the storage unit 120.

  For example, as shown in the following equation (1), digitized measurement values Xj of a plurality of sensor information from a plurality of sensors and respective coefficients are stored in a coefficient storage unit (not shown), and a two-dimensional matrix (matrix) The product-sum operation with the coefficient Aij represented by Then, as shown in the following equation (2), the result of the product-sum operation is calculated as an n-dimensional vector Yi using multidimensional coordinates. Note that i is the i coordinate in the n-dimensional space, and j is a number assigned to each sensor.

  Filtering processing that removes unnecessary sensor information from the acquired sensor information, and user behavior, state, and environment (TPO information) by performing arithmetic processing such as the above formulas (1) and (2) Analytical processing for estimation based on information can be realized. For example, if the coefficient A multiplied by the measured value X of the pulse (heart rate), the amount of sweat, and the body temperature is set to a value larger than the coefficient for the measured value of other sensor information, the above formulas (1) and (2 The numerical value Y calculated in () represents the “excitability” that is the user's state. In addition, by setting the coefficient multiplied by the measured value X of the utterance amount and the coefficient multiplied by the measured value X of the foot pressure to appropriate values, the user's behavior can sit and talk. It is possible to estimate whether the user is talking, walking, talking quietly, sleeping, or the like.

  Note that the user situation estimated by the situation estimation unit 106 is, for example, the user's behavior, state, or environment. The estimation of the user's behavior is based on the information of the behavior sensor worn by the user, and the state of the user's stationary / walking / running / sitting / laying down / stepping up / down the stairs is determined, or sensors (external) This can be realized by determining the user's action / posture state using a camera or a home sensor), or determining the user's staying / moving state based on the position locus obtained by the position detection sensor. The user's state is a user's mental state or physical state. The estimation of the user's state can be realized by discriminating stress, excitement, tension, health condition, etc. based on the information of the biosensor worn by the user. The user environment includes user location information, time information, ambient environment information, and the like. The user's environment is estimated by using the position detection sensor to determine where the user is staying (current location), using the clock to obtain the year, month, date, day of the week, and time, and using the ambient environment sensor to determine the temperature, atmospheric pressure, This can be achieved by acquiring noise. In this case, since it is difficult to completely and accurately specify the user situation based on the sensor information, the certainty of situation estimation by the situation estimation unit 106 has a certain range.

  Information other than sensor information may be used for estimating the user situation. Specifically, the user situation may be estimated using the user's schedule information (schedule data, schedule information) stored in the storage unit 120, or external information acquired via the communication unit 138 or the like. . For example, the user's future schedule is estimated based on the schedule table input by the user, or an incidental schedule is estimated from the input schedule. Alternatively, the user situation is estimated based on external information such as web information or information acquired from an external database via the Internet or the like (for example, today's weather / traffic information). If such schedule information or external information is used, the accuracy of situation estimation can be improved as compared with the case where the user situation is estimated using only sensor information. For example, by estimating the user's behavior by combining the sensor information and the schedule information, it is possible to estimate the user's behavior more reliably.

  Note that the situation estimation unit 106 (reaction determination unit 105) may estimate (determine) a user's reaction situation with respect to content based on operation information and sensor information. Further, the situation estimation unit 106 (reaction determination unit 105) may store history information that stores a user's response to the content in the history information storage unit 124. When the situation estimation unit 106 uses the operation information, the situation estimation unit 106 can have a reaction determination function that estimates a user's reaction situation with respect to the content. Alternatively, when the situation estimation unit 106 does not use schedule information or external information, the reaction determination unit 105 having only the reaction determination function can be separated from the situation estimation unit 106.

  The base content selection unit 108 performs base content selection processing. Specifically, at least one base content related to the user situation estimated by the situation estimation unit 106 is selected (extracted) from the plurality of base contents stored in the storage unit 120. The base content may be selected based on the history information that stores the user reaction stored in the storage unit 120.

  The presentation permitted content selection unit 110 performs a process for selecting presentation permitted content. Specifically, at least one presentation permission content related to the user situation estimated by the situation estimation unit 106 is selected (extracted) from among the plurality of presentation permission contents stored in the storage unit 120. In addition, you may select presentation permission content based on the log | history information which stores the reaction of the user memorize | stored in the memory | storage part 120, and a user's achievement level.

  The theme registration processing unit 112 performs theme registration indicating that the user has permitted presentation of presentation-permitted content belonging to a given theme, whereby the presentation-permitted content selection unit 110 selects presentation-permitted content belonging to a given theme. It becomes selectable. In other words, the theme registration processing unit 112 performs a process for enabling the presentation permitted content selection unit 110 (for example, a process for setting the execution state). Specifically, basically, the base content selection unit 108 can always select base content, while theme registration indicating that the user has permitted the presentation permission of the presentation permission content belonging to the given theme is performed. After that, the presentation permitted content selection unit 110 can select the presentation permitted content. When theme registration is not performed by the theme registration processing unit 112, the presentation permitted content selection unit 110 cannot select the presentation permitted content. In addition, when there are a plurality of themes of presentation permission content, the theme registration processing unit 112 performs theme registration for each theme, and the presentation permission content selection unit 110 selects the presentation permission content belonging to all the themes for which theme registration has been performed. It becomes possible.

  The presentation control unit 114 performs processing for selecting content that is a candidate for presentation to the user. Specifically, the content to be presented to the user is selected (determined) from the content presentation unit such as the wearable display 140 from the base content and the presentation permitted content stored in the storage unit 120. For example, when the base content selection unit 108 can select the base content and the presentation permitted content selection unit 110 cannot select the presentation permitted content, the presentation control unit 114 provides the content presentation unit to the user. The base content extracted by the base content selection unit 108 is determined as the content to be presented. For example, when both the base content selection unit 108 and the presentation permitted content selection unit 110 can select content, the presentation control unit 114 sets the base content selection unit as content to be presented to the user by the content presentation unit. The base content extracted by 108 and the base content extracted by the presentation permitted content selection unit 110 are determined. For example, when the display size of the content presentation unit 140 is small, the presentation control unit 114 may select the presentation permitted content with priority over the base content.

  The presentation control unit 114 may select various menu screens stored in the storage unit 120 based on the degree of interest and the achievement level as the content presented to the user by the content presentation unit.

  The interest level evaluation unit 116 performs an interest level evaluation process. Specifically, the interest level of the theme of the presentation permitted content is evaluated (determined) based on the base content. For example, based on the genre of the base content, the user's interest in the theme of the presentation permitted content is evaluated, and at this time, the evaluation point of each genre is calculated for each theme or the table storing the evaluation points of each genre. Possible expressions may be used. Further, the interest level evaluation unit 116 may evaluate (determine) the user's second interest level with respect to the theme of the presentation permitted content based on the presentation permitted content. For example, the second interest level of the user with respect to the theme is evaluated based on the theme of the presentation permitted content. Note that the interest level evaluation unit 116 may update the interest level information stored in the storage unit 120 based on the operation information and the sensor information. Note that the interest level evaluation unit 116 may determine whether the interest level exceeds a threshold value.

  The achievement degree evaluation unit 118 performs achievement degree evaluation processing. Specifically, the achievement level of the theme of the presentation permitted content is evaluated (determined). The achievement level evaluation unit 118 can update the achievement level information stored in the storage unit 120 based on the operation information and the sensor information. At this time, a table or an expression for calculating the achievement level may be used.

  The storage unit 120 serves as a work area for the processing unit 102, the communication unit 138, and the like, and functions thereof can be realized by a memory such as a RAM or an HDD (hard disk drive). The memory | storage part 120 may memorize | store information permanently and may memorize | store information temporarily. The storage unit 120 includes a content information storage unit 122, a history information storage unit 124, an interest level information storage unit 126, and an achievement level information storage unit 128. Various modifications such as omitting some of these components (for example, a history information storage unit and an interest level information storage unit) and adding other components are possible.

  The content information storage unit 122 (content database) stores content information such as text (characters, sentences), images, video, music, audio, or various data. This content may be generated in real time, or may be downloaded from the outside via the communication unit 138, for example. The content information storage unit 122 can store meta information (additional information) associated with the content. The content type includes at least base content and presentation permitted content. For example, the base content can have genre information as meta information. The base content may be acquired from the outside (for example, information on the Internet) using the genre as a search key via the communication unit 138, for example. For example, the presentation permitted content can have theme information as meta information.

  The history information storage unit 124 stores history information for storing the estimated user situation and history information for storing a user reaction to the content. For example, for each content presented to the content presentation unit 140, the user's situation, presence / absence of a reaction to the content, and the type of the content (genre of base content or theme of presentation permitted content) are stored. The history information storage unit 124 may store, for each theme, a usage history of a genre that can be used for a user interest level evaluation process as history information for storing a user's reaction to the base content.

  The interest level information storage unit 126 stores information on the interest level of the user. For example, information on the user's interest level with respect to the theme related to the genre of the base content and information on the user's second interest level with respect to the theme of the presentation permitted content are stored.

  The achievement level information storage unit 128 stores information on the achievement level of the user. Specifically, information on the achievement level of the user with respect to the theme of the presentation permitted content is stored.

  The information storage medium 130 (a computer-readable medium) stores programs, data, and the like, and its function can be realized by an optical disk (CD, DVD) or the like. The processing unit 102 performs various processes of the present embodiment based on a program (data) stored in the information storage medium 130. That is, in the information storage medium 130, a program for causing a computer (an apparatus including an operation unit, a processing unit, a storage unit, and an output unit) to function as each unit of the present embodiment (a program for causing the computer to execute processing of each unit). Is memorized.

3. Initial Startup Operation An example of the initial startup operation according to this embodiment will be briefly described with reference to FIGS. 3 (A) and 3 (B). FIG. 3A shows a conceptual diagram of the initial activation operation of the base content selection unit and the presentation permitted content selection unit, and FIG. 3B shows a presentation example of the content presentation unit. As shown in FIG. 3A, when the information presentation system is initially activated, the base content selection unit 108 can basically select the base content. After the theme registration indicating that the user has permitted the presentation of the presentation permitted content belonging to the given theme is performed in the information presentation system by the theme registration processing unit 112, basically, the presentation permitted content selection unit 110 Presentation permission content belonging to a given theme can be selected. As shown in FIG. 3B, the content presentation unit 140 presents a menu screen for performing theme registration indicating that the user has permitted presentation of presentation-permitted content belonging to a certain theme (for example, improvement in eating habits). can do. After the user's will is confirmed via the menu screen, the theme registration processing unit 112 performs theme registration indicating that the user has permitted the presentation permitted content belonging to the theme.

  Next, an example of an initial startup operation according to this embodiment will be described with reference to FIGS. 4 (A) and 4 (B). 4A is a flowchart regarding the initial activation of the presentation permitted content selection unit, and FIG. 4B is an explanatory diagram of the initial activation method of the presentation permitted content selection unit.

  First, the presentation permitted content selection unit 110 determines whether theme registration indicating that the user has permitted presentation of the presentation permitted content belonging to the given theme has been performed (step S1). When theme registration is not performed, the theme registration process part 112 implements step S1 again. When theme registration is performed, the presentation permission content selection part 110 can select the presentation permission content which belongs to a given theme (step S2). In this way, since the user's will is confirmed, even if the presentation permitted content induces the user's behavior, for example, the user is not easily subjected to psychological pressure. Therefore, the user's psychological burden is reduced.

  In step S1, specifically, the presentation-permitted content selection unit 110 determines whether theme registration has been performed via the theme registration processing unit 112 (reaction determination unit 105). For example, the presentation permitted content selection unit 110 refers to theme registration information stored in the storage unit 120 and determines whether theme registration has been performed on the theme registration information.

  In step S1, specifically, the reaction determination unit 105 determines whether or not the operation information from the operation unit 160 affirms theme registration. The reaction determination unit 105 may use sensor information from the wearable sensor 150 (for example, the line-of-sight sensor 562) instead of the operation information from the operation unit 160. The presentation control unit 114 notifies the reaction determination unit 105 that a menu (for example, FIG. 3B) for performing theme registration is selected (determined), and the reaction determination unit 105 is based on this notification. Then, it is determined whether or not the operation information and sensor information affirm the theme registration. When the operation information or the sensor information affirms theme registration, the theme registration processing unit 112 performs theme registration on the theme registration information stored in the storage unit 120.

4). Presentation Operation An example of the presentation operation of the present embodiment will be briefly described with reference to FIG. FIG. 5 shows a presentation example of the content presentation unit. When both the base content selection unit 108 and the presentation permitted content selection unit 110 can select content, as shown in FIG. 5, the content presentation unit 140 can present the base content and the presentation permitted content. In FIG. 5, three base contents are presented as indicated by A1, A2, and A3, and one presentation permitted content is indicated as indicated by A4. In FIG. 5, the genre of the base content shown in A1 (new influenza vaccine child vaccination starts to trial) is “News”, and the genre of the base content shown in A2 (Diet feature) is “Diet”. Yes, the genre of the base content shown in A3 (the economy moves with emotion [AB Bookstore]) is “Regional information”, and the theme of the presentation-permitted content shown in A4 (let's keep the amount of meals conserved) is “ “Improving eating habits”.

  Next, a presentation operation example of the present embodiment will be described with reference to FIGS. 6 (A) and 6 (B). FIG. 6A is a flowchart regarding selection of the presentation control unit, and FIG. 6B is an explanatory diagram of a selection method of the presentation control unit.

  First, the information acquisition unit 104 acquires sensor information from a behavior sensor, a state sensor, or an environment sensor (step S11). And the situation estimation part 106 estimates a user's condition (TPof) based on the acquired sensor information (step S12). Next, the base content selection unit 108 selects a plurality of contents (for example, a plurality of base contents stored in the content information storage unit 122) based on the user situation estimated (identified) by the sensor information. At least one base content is selected (extracted) (step S13). Further, the presentation permitted content selection unit 110 selects from among a plurality of contents (for example, a plurality of presentation permitted contents stored in the content information storage unit 122) based on the user situation estimated (identified) by the sensor information. Then, at least one presentation permitted content is selected (extracted) (step S13). The sensor information used for the presentation permitted content selection unit 110 may be the same sensor information as the sensor information used for the base content selection unit 108 or may be dedicated sensor information.

  Next, as the content presented to the user by the content presentation unit 140, the presentation control unit 114 extracts the base content extracted by the base content selection unit 108, and the presentation permitted content extracted by the presentation permitted content selection unit 110. Are selected (determined) (step S14). Then, the presentation control unit 114 presents (provides and displays) the selected (determined) base content and presentation permitted content to the user by an information presentation unit such as the wearable display 140 (step S15, for example, FIG. 5).

  The situation estimation unit 106 may use information such as user schedule information acquired via the information acquisition unit 104 and external information acquired from the outside. The presentation control unit 114 may select (determine) only the base content extracted by the base content selection unit 108, ignoring the presentation permitted content extracted by the presentation permitted content selection unit 110. Alternatively, the presentation control unit 114 may ignore the base content extracted by the base content selection unit 108 and select (determine) only the presentation permitted content extracted by the presentation permitted content selection unit 110.

  In step S13 of FIG. 6A, the base content selection unit 108 can basically extract the base content. When theme registration is performed as shown in steps S1 and S2 of FIG. 4A, the presentation permitted content selection unit 110 sets the theme permitted by the user in step S13 of FIG. The presentation-permitted content to which it belongs can be extracted.

5). Interest Level Evaluation Operation Based on Base Content The interest level evaluation operation based on the base content of the present embodiment can be divided into two stages. That is, the interest level evaluation operation based on the base content can be divided into an interest level update operation based on the base content and an interest level determination operation based on the base content. By adopting the interest level evaluation operation based on the base content in the present embodiment, the information presentation system can estimate a range in which the user is interested to some extent. Therefore, the information presentation system can propose presentation permission content based on the estimated degree of interest of the user. When the degree of interest of the user is taken into account, some users are likely to be newly aware of the presentation permission content proposal. On the other hand, when the degree of interest of the user is not taken into account, some users are likely to be anxious or uncomfortable with the proposal of the presentation permitted content (request for theme registration). In addition, by adopting the interest level determination operation based on the base content, the information presentation system can propose the presentation permitted content when the user's level of interest becomes high.

  An example of interest level update operation based on the base content of the present embodiment will be briefly described with reference to FIGS. 7A, 7B, and 8A. 7A and 7B show examples of presentation by the content presentation unit. FIG. 8A shows an example of a table for converting a response to the base content into an interest level. FIG. 7A shows a situation where the user is about to respond (select) to the base content (diet feature) shown in A2 in FIG. 5 via the operation unit 160 or a sensor. After the user has reacted to the base content (diet feature) shown in A2, in FIG. 7B, a detailed screen showing the continuation of the base content shown in A2 is presented. The detailed screen includes three base contents as shown in B1, B2, and B3. In FIG. 8A, when the genre “diet” of the base content (diet feature) shown in A2 in FIG. 5 corresponds to the genre 19, the evaluation point for the theme 2 (food habit improvement) is 10.

  Note that the genre usage history may be stored for each theme in the interest level evaluation based on the base content of the present embodiment. FIG. 8B shows an example of a table for storing a response to the base content as a genre usage history. In FIG. 8B, the number of reactions to the base content and the presence / absence of use for interest level evaluation are stored for each genre that can be used for interest level evaluation for each theme. Each value in the storage table in FIG. 8B corresponds to an evaluation point value other than “0” in the conversion table (evaluation point table) in FIG.

  Next, an example of interest level update operation according to the present embodiment will be described with reference to FIGS. 9 (A) and 9 (B). FIG. 9A is a flowchart regarding the update of the interest level evaluation unit based on the base content, and FIG. 9B is an explanatory diagram of the update method of the interest level evaluation unit based on the base content.

  First, the reaction determination unit 105 determines whether or not the user has reacted to the base content (step S21). When the user reacts to the base content, the interest level evaluation unit 116 evaluates the user's interest level with respect to the theme of the presentation permitted content based on the base content (step S22). Then, the interest level evaluation unit 116 updates the user's interest level for the theme based on the base content (step S23). When the user reacts to the base content, the reaction determination unit 105 may update the user's usage history for a genre that can be used for evaluating the degree of interest of the user (step S24).

  In step S21, specifically, the reaction determination unit 105 determines whether or not the operation information from the operation unit 160 indicates that the user has reacted to the base content. The reaction determination unit 105 may use sensor information from the wearable sensor 150 instead of the operation information from the operation unit 160. The presentation control unit 114 notifies the reaction determination unit 105 that the base content has been selected (determined), and the reaction determination unit 105 responds to the operation information and sensor information from the user based on this notification. It is determined whether it represents what has been done.

  For example, the reaction determination unit 105 represents the selection of the base content (for example, FIG. 7A) whose operation information or sensor information is selected (determined) by the presentation control unit 114, and as a result, continues the base content. The response determination unit 105 determines that the operation information and the sensor information indicate that the user has reacted to the base content, based on the details screen (for example, FIG. 7B). In this case, the reaction determination unit 105 may notify the base content selection unit 108 that a subsequent detail screen is requested.

  In step S22, specifically, the interest level evaluation unit 116 evaluates the user's interest level with respect to the theme based on the genre of the base content to which the user has reacted. The presentation control unit 114 notifies the interest level evaluation unit 116 of the genre of the base content that is selected (determined), and the interest level evaluation unit 116 applies to the theme based on the genre of the base content from the presentation control unit 114. Assess user interest. The presentation control unit 114 may notify the interest level evaluation unit 116 of the ID of the base content selected (determined). The interest level evaluation unit 116 refers to the content information storage unit 122 while presenting the presentation control unit. The genre of the base content corresponding to the ID of the base content from 114 may be acquired, and the user's interest in the theme may be evaluated based on the acquired genre.

  In step S <b> 22, specifically, the interest level evaluation unit 116 uses a table (for example, FIG. 8A) that stores evaluation points of each genre for each theme stored in the storage unit 120. The genre of the reacted base content is converted (evaluated) into the user's interest level with respect to the theme. The table that stores the evaluation points of each genre for each theme may be an expression that can calculate the evaluation points of each genre for each theme. Note that the interest level evaluation unit 116 may evaluate the interest levels of a plurality of users corresponding to a plurality of themes.

  Specifically, in step S23, the interest level evaluation unit 116 reads the user's interest level with respect to the pre-evaluation theme from the interest level information storage unit 126, and evaluates the user's interest level before the evaluation after evaluating the user's interest level. Update to For example, the interest level of theme 2 (eating habit improvement) before evaluation (response) is “995”, and the evaluation point for theme 2 (eating habit improvement) after evaluation (response) is “10” (for example, FIG. 8). In the case of (A)), the interest level of the updated theme 2 (food habit improvement) is “1005” (= “995” + “10”). Note that the interest level evaluation unit 116 may update the interest levels of a plurality of users corresponding to a plurality of themes.

  When the presentation control unit 114 selects the base content as shown in step S14 of FIG. 6A, in step S21 of FIG. 9A, the reaction determination unit 105 determines whether or not the user has reacted to the base content. Can be determined.

  When the user responds to the base content, in steps S22 and S23, the interest level evaluation unit 116 evaluates and updates the user's interest level with respect to the theme based on the genre of the base content to which the user has responded. At this time, in step S <b> 24, the reaction determination unit 105 may update the user's usage history for the genre that can be used to evaluate the user's interest level. The use history of the user is used in step S35 of FIG.

  In step S24, specifically, the reaction determination unit 105 reads the genre usage history from the history information storage unit 124, and reacts to the genre (for example, genre 19) of the base content selected (reacted) by the user. Update the number of times for each theme. For example, if the number of reactions in genre 19 (diet) of theme 1 (increase walking amount) and theme 2 (eating habit improvement) before selection (response) is “0” (for example, FIG. 8B), select The number of reactions in genre 19 (diet) of theme 1 (increase in walking amount) and theme 2 (eating habit improvement) after (reaction) is updated from “0” to “1”.

  When the number of reactions of the genre (for example, genre 19) of the base content selected (reacted) by the user is updated from “0” to “1”, the reaction determination unit 105 determines the interest level evaluation of the genre. Also update availability. For example, when the usage flag of genre 19 (diet) of theme 1 (increase in walking amount) and theme 2 (eating habit improvement) before selection (reaction) is “0” (for example, FIG. 8B), selection The usage flag of genre 19 (diet) of theme 1 (increase in walking amount) and theme 2 (eating habit improvement) after (reaction) is updated from “0 (unused)” to “1 (used)”. . Note that each value in the storage table of FIG. 8B corresponds only to a genre that can be used to evaluate the user's interest level with respect to the theme of the presentation permitted content. For example, since the evaluation point value of the genre 5 (sports practice improvement) of the theme 2 (eating habit improvement) in the conversion table of FIG. 8A is “0”, the genre 5 (sports improvement of the theme 2 (eating habit improvement) It is impossible to memorize the number of responses of (practice) and the presence / absence of use in the interest level evaluation.

  Next, an example of the interest level determination operation based on the base content according to the present embodiment will be briefly described with reference to FIGS. FIG. 10 shows an example of setting the interest level threshold of the presentation permitted content based on the base content. FIG. 11 shows a presentation example of the content presentation unit.

  For example, as shown in FIG. 10, when the interest level of theme 2 (eating habit improvement) exceeds the interest level threshold, content presentation unit 140 displays theme 2 (eating habit improvement) as shown in FIG. It is possible to present a menu screen for performing theme registration of the presentation permitted content belonging to the category.

  Unlike the example of FIG. 10, for example, when the interest level of the theme 1 (walking amount increase) exceeds the interest level threshold, the content presentation unit 140 is related to the theme 1 (walking amount increase) as illustrated in FIG. 11. Interest confirmation content may be presented. In this case, after the user reacts to the interest confirmation content, the content presentation unit 140 can present a menu screen for performing the theme registration of the presentation permitted content belonging to the theme 1 (increase in walking amount). Note that a different interest level threshold may be set for each theme.

  Next, an example of the interest level determination operation of the present embodiment will be described with reference to FIGS. 12 (A) and 12 (B). FIG. 12A is a flowchart relating to determination of interest level, and FIG. 12B is an explanatory diagram of a determination method of interest level.

  First, the degree-of-interest evaluation unit 116 determines whether or not the degree of interest of the user with respect to the theme of the presentation-permitted content based on the base content exceeds a given interest level threshold (step S31). Next, when the degree of interest of the user with respect to the theme exceeds a given interest level threshold, the presentation control unit 114 performs theme registration indicating that the user has permitted the presentation of the presentation permitted content belonging to the given theme. Menu screen is selected (step S32).

  When the user's interest level for the theme exceeds a given interest level threshold, the reaction determination unit 105 may determine whether or not the user has reacted to the interest confirmation content (step S33). When the user responds to the interest confirmation content, the presentation control unit 114 may select a menu screen for performing theme registration indicating that the user has permitted the presentation permitted content belonging to the given theme ( Step S32).

  Specifically, in step S31, the interest level evaluation unit 116 acquires the user's interest level with respect to the theme of the presentation permitted content based on the base content from the interest level information storage unit 126, and stores the given interest level threshold value. Obtain from 120. For example, the degree of interest of the user with respect to theme 2 (food habit improvement) is “1005”. The degree-of-interest evaluation unit 116 determines whether or not the degree of interest of the user with respect to the theme of the presentation-permitted content based on the base content exceeds a given interest level threshold. The given interest level threshold is, for example, “1000”. When the degree of interest of the user with respect to the theme of the presentation permitted content based on the base content exceeds a given interest level threshold, the interest level evaluation unit 116 determines that the degree of interest of the user with respect to the theme of the presentation permitted content based on the base content is given. The presentation control unit 114 is notified that the interest level threshold is exceeded.

  In step S32, specifically, the presentation control unit 114 performs menu registration (for example, FIG. 3B) for performing theme registration indicating that the user has permitted the presentation of the presentation permitted content belonging to the given theme. ) Is read from the content information storage unit 122 and its menu screen is selected. The content presentation unit 140 presents a menu screen for performing theme registration to the user in response to this selection.

  The interest level evaluation unit 116 may notify the base content selection unit 108, not the presentation control unit 114, that the user's interest level for the presentation permitted content theme based on the base content exceeds a given interest level threshold. The base content selection unit 108 may select the interest confirmation content as the base content. In this case, the presentation control unit 114 displays the interest confirmation content from the base content selection unit 108 instead of the menu screen for performing the theme registration indicating that the user has permitted the presentation of the presentation permitted content belonging to the given theme. May be selected. Unlike the example of FIG. 10, for example, when the interest level of the user for the theme 1 (increase in walking amount) is “1005” and the given interest level threshold is “1000”, the interest level evaluation unit 116 The base content selection unit 108 is notified that the interest level of the user with respect to theme 1 (increase in walking amount) exceeds a given interest level threshold. In this case, the base content selection unit 108 stores, for example, the interest confirmation content shown in FIG. 11 (passed the walk course. If you return to the place where you were five minutes ago, you can guide the walk course). The content is read from the unit 122 and the interest confirmation content is selected. The presentation control unit 114 notifies the reaction determination unit 105 that the interest confirmation content from the base content selection unit 108 is selected.

  In step S33, specifically, the reaction determination unit 105 determines whether or not the wearable sensor 150 (for example, the GPS sensor 550) indicates that the user has reacted to the interest confirmation content. The reaction determination unit 105 may use operation information from the operation unit 160 instead of the sensor information from the wearable sensor 150. When the user reacts to the interest confirmation content, the reaction determination unit 105 notifies the presentation control unit 114 that the user has reacted to the interest confirmation content. Based on this notification, the presentation control unit 114 selects a menu screen for performing theme registration indicating that the user has permitted presentation of the presentation permitted content belonging to the given theme (step S32).

  As shown in step S23 of FIG. 9A, when the interest level evaluation unit 116 updates the interest level of the user with respect to the theme of the presentation permitted content based on the base content, in step S31 of FIG. The degree evaluation unit 116 can determine whether or not the degree of interest of the user with respect to the theme of the presentation permitted content based on the base content exceeds a given interest degree threshold.

  As described above, for example, as illustrated in FIG. 10, when the interest level of theme 2 (food habit improvement) exceeds the interest level threshold, as illustrated in FIG. It is possible to present a menu screen for performing theme registration of presentation-permitted content belonging to (food habit improvement) (step S32 in FIG. 12A). However, the theme presented on the menu screen does not necessarily create new awareness for the user. Therefore, when the interest level of the theme does not exceed the interest level threshold value, it is preferable to present base contents of various genres and determine a user's reaction to each base content. In addition to this, or instead of this, it is preferable to employ a plurality of interest level thresholds.

  An example of a presentation operation based on the degree of interest evaluated based on the base content of the present embodiment will be described with reference to FIGS. 13 (A) and 13 (B). FIG. 13A is a flowchart relating to the presentation of base content, and FIG. 13B is an explanatory diagram of a method for presenting base content. Note that the flowchart in FIG. 13A can be said to be a modification of the flowchart in FIG. In FIG. 12A, one interest level threshold is adopted, while in FIG. 13A, two interest degree thresholds (low threshold and high threshold) are adopted. Unlike the example of FIG. 10, for example, the threshold shown in FIG. 10 may be set as a low threshold, and a threshold (not shown) above the threshold shown in FIG. 10 may be set as a high threshold. Alternatively, for example, a threshold value (not shown) below the threshold value shown in FIG. 10 may be set as a low threshold value, and the threshold value shown in FIG. 10 may be set as a high threshold value.

  First, the base content selection unit 108 randomly selects at least one genre from a plurality of genres, and selects at least one base content corresponding to the at least one genre selected at random (step S34). . Next, the interest level evaluation unit 116 determines whether or not the user's interest level with respect to the theme of the presentation permitted content based on the base content exceeds a low threshold (step S31). If the user's interest in the theme does not exceed the low threshold, step S34 is performed. When the user's interest in the theme exceeds a low threshold, the base content selection unit 108 non-randomly selects at least one genre from a plurality of genres, and sets the non-randomly selected at least one genre. At least one corresponding base content is selected (step S35). Next, the interest level evaluation unit 116 determines whether or not the user's interest level with respect to the theme of the presentation permitted content based on the base content exceeds a high threshold value (step S31 '). If the user's interest in the theme does not exceed the high threshold, step S35 is performed. When the degree of interest of the user with respect to the theme exceeds a high threshold, the presentation control unit 114 selects a menu screen for performing theme registration indicating that the user has permitted the presentation of the presentation permitted content (step S32).

  If the user's interest in the theme does not exceed the high threshold even if the determination in step S31 ′ is performed a given number of times, step S34 is performed instead of step S35, and steps S31 and S35 are performed. You can ignore it. Alternatively, steps S34, S31 may be ignored and steps S35, S31 ', S32 may be performed.

  Specifically, in step S34, as shown in FIG. 3A, after the information presentation system is initially activated, the base content selection unit 108 is configured as long as the user's interest in the theme does not exceed a low threshold. At least one genre is randomly selected from a plurality of genres, and at least one base content corresponding to the at least one genre selected at random is selected. For example, as shown in FIG. 8A, when the number of genres of base content is 28, the probability of selecting genre 1 from genres 1 to 28 is genre 2 from genres 1 to 28. Equal to the probability of selecting. By selecting the genre of the base content at random, it becomes possible to effectively grasp which theme the user is interested in.

  When the base content selection unit 108 selects the base content and the presentation control unit 114 also selects the base content, the reaction determination unit 105 receives the operation information from the operation unit 160 and the sensor information from the wearable sensor 150 by the user. It is determined whether or not it represents that the content has been reacted. When the user reacts to the base content, the interest level evaluation unit 116 evaluates the user's interest level for the theme based on the genre of the base content to which the user responded. The interest level evaluation unit 116 reads the user's interest level for the theme before evaluation from the interest level information storage unit 126, and updates the user's interest level before evaluation to the user's interest level after evaluation.

  Specifically, in step S31, when the interest level of the user before evaluation is updated to the interest level of the user after evaluation, the interest level evaluation unit 116 acquires a low threshold value from the storage unit 120. For example, the user's interest level (updated interest level) for theme 2 (food habit improvement) is “505”. The degree-of-interest evaluation unit 116 determines whether the degree of interest of the user with respect to the theme of the presentation permitted content based on the base content exceeds a low threshold. The low threshold is “500”, for example. When the user's interest in the presentation permitted content theme based on the base content exceeds a low threshold, the interest level evaluation unit 116 indicates that the user's interest in the presentation permitted content theme based on the base content exceeds a low threshold. To the base content selection unit 108.

  In step S35, specifically, as shown in FIG. 3A, after the degree of interest of the user with respect to the theme exceeds the low threshold, the base of the user unless the degree of interest of the user with respect to the theme exceeds the high threshold. The content selection unit 108 selects at least one genre from a plurality of genres non-randomly, and selects at least one base content corresponding to the at least one genre selected non-randomly. For example, as shown in FIG. 8A, when the number of genres of base content is 28, the probability of selecting genre 1 from genres 1 to 28 for theme 1 is genres 1 to 28 for theme 1. This is not equal to the probability of selecting genre 5 from the list. A method for non-randomly selecting at least one genre from among a plurality of genres will be described later with reference to FIG.

  When the base content selection unit 108 selects the base content and the presentation control unit 114 also selects the base content, the reaction determination unit 105 receives the operation information from the operation unit 160 and the sensor information from the wearable sensor 150 by the user. It is determined whether or not it represents that the content has been reacted. When the user reacts to the base content, the interest level evaluation unit 116 evaluates the user's interest level for the theme based on the genre of the base content to which the user responded. The interest level evaluation unit 116 reads the user's interest level for the theme before evaluation from the interest level information storage unit 126, and updates the user's interest level before evaluation to the user's interest level after evaluation.

  Specifically, in step S <b> 31 ′, when the interest level of the user before evaluation is updated to the interest level of the user after evaluation, the interest level evaluation unit 116 acquires a high threshold value from the storage unit 120. For example, the user's interest level (updated interest level) for theme 2 (food habit improvement) is “1005”. The degree-of-interest evaluation unit 116 determines whether the degree of interest of the user with respect to the theme of the presentation permitted content based on the base content exceeds a high threshold. The high threshold is, for example, “1000”. When the degree of interest of the user with respect to the theme of the presentation permitted content based on the base content exceeds a high threshold, the interest level evaluation unit 116 indicates that the degree of interest of the user with respect to the theme of the presentation permitted content based on the base content exceeds the high threshold. Is notified to the presentation control unit 114.

  Specifically, in step S32, the presentation control unit 114 displays a menu screen (for example, FIG. 3B) for performing theme registration indicating that the user has permitted the presentation of the presentation permitted content, as the content information storage unit. Read from 122 and select the menu screen. The content presentation unit 140 presents a menu screen for performing theme registration to the user in response to this selection.

  Hereinafter, a method for non-randomly selecting at least one genre from among a plurality of genres will be described. In step S35, when the degree of interest of the user with respect to the theme of the presentation permitted content exceeds a low threshold, the base content selection unit 108 uses, for example, a genre that can be used to evaluate the degree of interest of the user with respect to the theme of the presentation permitted content At least one base content is selected based on the history (for example, the number of reactions to the base content in FIG. 8B and the presence / absence of use for interest level evaluation). In addition to this, or instead of this, for example, the base content selection unit 108 uses an evaluation point of a genre that can be used for evaluating the user's interest level with respect to the theme of the presentation permitted content (for example, FIG. 8A). And selecting at least one base content.

  Specifically, in the usage history of the genre shown in FIG. 8B, the genres used for the evaluation of the user's interest level with respect to the theme 2, for example, are genres 4, 6, 7, 8, 15 and are not used. The genres are genres 11, 12, and 19. The base content selection unit 108 can select the base content belonging to the unused genre with priority over the base content belonging to the used genre. For example, the base content selection unit 108 can select only base content belonging to an unused genre. By ascertaining whether or not the user reacts to the base content belonging to the unused genre, it becomes possible to surely understand which theme the user is interested in.

  Specifically, in the evaluation table shown in FIG. 8A, for example, compared with base contents belonging to genres 4, 6, 7, 8, 11, 12, 15 having a low evaluation point for theme 2, for example, Base content belonging to the genre 19 having a high evaluation point with respect to the theme 2 can be selected with priority. When the user reacts to base content belonging to a genre having a high point, it is possible to quickly grasp whether the user is interested in the theme. For example, the base content selection unit 108 can select only the genre having the highest evaluation point.

  In step S35, the base content selection unit 108 may select the base content belonging to the genre having the highest evaluation point or the highest evaluation point from the unused genres for the given theme. If there is no unused genre, steps S35 and S31 'may be ignored.

6). Interest level evaluation operation based on presentation permitted content The above-described processing based on the base content has been described with reference to FIGS. 9A, 9B, 12A, and 12B. 116 may perform a degree-of-interest evaluation process for the presentation permitted content. The interest level evaluation operation based on the base content makes it possible to perform theme registration based on the estimated level of interest of the user and present the presentation permitted content to the user. However, the estimated interest level of the user may not match the actual interest level of the user (the interest level lurking in the user's mind). Therefore, even when the theme registration is performed, in order to confirm the user's interest level again, the present embodiment can employ the interest level evaluation operation based on the presentation permitted content. The degree of interest of the user after theme registration has been performed can be referred to as the second degree of interest. The interest level evaluation operation based on the presentation permitted content can be divided into an interest level update operation based on the presentation permitted content and an interest level determination operation based on the presentation permitted content.

  An example of the interest level update operation based on the presentation permitted content of the present embodiment will be briefly described with reference to FIGS. 14 (A) and 14 (B). 14A and 14B show examples of presentation by the content presentation unit. In FIG. 14A, the presentation permission content (Do you take a note of the meal content?) Belonging to theme 2 (meal habit improvement) is shown. In FIG. 14B, presentation permission content (let's get off at AB station and take a walk) belonging to theme 1 (increase in walking amount) is shown. The reaction determination unit 105 evaluates the second degree of interest of the user with respect to the theme of the permitted content as shown in FIG. 14 (A) or FIG. 14 (B).

  Next, an example of interest level update operation according to the present embodiment will be described with reference to FIGS. 15 (A) and 15 (B). FIG. 15A is a flowchart regarding the update of the interest level evaluation unit based on the presentation permitted content, and FIG. 15B is an explanatory diagram of the update method of the interest level evaluation unit based on the presentation permitted content.

  First, the reaction determination unit 105 determines whether or not the user has reacted to the presentation permitted content (step S41). When the user reacts to the presentation permission content, the interest level evaluation unit 116 evaluates the second interest level of the user with respect to the theme of the presentation permission content based on the presentation permission content (step S42). Then, the degree-of-interest evaluation unit 116 updates the second degree of interest of the user with respect to the theme based on the presentation permitted content (step S43).

  In step S41, specifically, the reaction determination unit 105 determines whether or not the operation information from the operation unit 160 indicates that the user has reacted to the presentation permitted content. The reaction determination unit 105 may use sensor information from the wearable sensor 150 (for example, the line-of-sight sensor 562, the GPS sensor 550, etc.) instead of the operation information from the operation unit 160. The presentation control unit 114 notifies the reaction determination unit 105 that the presentation permitted content is selected (determined), and the reaction determination unit 105 determines that the operation information and the sensor information are provided by the user based on the notification. It is determined whether or not it represents that it has reacted.

  For example, the reaction determination unit 105 selects or obeys the presentation permission content (for example, FIG. 14 (A), FIG. 14 (B), etc.) selected (decided) by the presentation control unit 114 for the operation information and sensor information. Thus, the reaction determination unit 105 determines that the operation information and sensor information indicate that the user has reacted to the presentation permitted content.

  In step S42, specifically, the degree-of-interest evaluation unit 116 evaluates the second degree of interest of the user with respect to the theme based on the theme of the presentation permitted content that the user has reacted to. The presentation control unit 114 notifies the interest level evaluation unit 116 of the theme of the presentation permitted content selected (determined), and the interest level evaluation unit 116 is based on the theme of the presentation permitted content from the presentation control unit 114. Evaluate the user's second interest in the theme. The presentation control unit 114 may notify the interest level evaluation unit 116 of the ID of the presentation permitted content selected (determined), and the interest level evaluation unit 116 refers to the content information storage unit 122 and performs presentation control. The theme of the presentation permission content corresponding to the ID of the presentation permission content from the unit 114 may be acquired, and the degree of interest of the second user with respect to the theme may be evaluated based on the acquired theme.

  In step S43, specifically, the interest level evaluation unit 116 reads the second interest level of the user for the theme before evaluation from the interest level information storage unit 126, and evaluates the second interest level of the user before evaluation. Update to the second user's second interest level. For example, the second interest level of theme 2 (eating habit improvement) before evaluation (reaction) is “0”, and the evaluation point for theme 2 (eating habit improvement) after evaluation (reaction) is “10”. In this case, the degree of interest in the updated theme 2 (meal habit improvement) is “10” (= “0” + “10”).

  When the presentation control unit 114 selects the presentation permitted content as shown in step S14 of FIG. 6A, in step S41 of FIG. 15A, the reaction determination unit 105 responds to the presentation permitted content. It can be determined whether or not. The situation estimation unit 106 may perform the process of the reaction determination unit 105.

  Next, an interest level determination operation example based on the presentation permitted content of the present embodiment will be briefly described with reference to FIGS. 16 and 17. FIG. 16 shows an example of setting a second interest level threshold for presentation permitted content based on the presentation permitted content. FIG. 17 shows a presentation example of the content presentation unit.

  For example, as shown in FIG. 16, when the second interest level of theme 2 (meal habit improvement) does not exceed the second interest level threshold value in a given period, as shown in FIG. 140 can present a menu screen for canceling the theme registration of presentation-permitted content belonging to theme 2 (meal habit improvement). A different given period may be set for each theme, and a different second interest level threshold may be set.

  Next, an example of the interest level determination operation of the present embodiment will be described with reference to FIGS. 18 (A) and 18 (B). FIG. 18A is a flowchart regarding the determination of the second interest level, and FIG. 18B is an explanatory diagram of the second interest level determination method.

  First, the interest level evaluation unit 116 determines whether or not the second interest level of the user with respect to the theme of the permitted presentation content based on the permitted presentation content exceeds the given second interest level threshold in a given period. (Step S51). Next, when the second interest level of the user with respect to the theme does not exceed the given second interest level threshold value in the given period, the presentation control unit 114 displays the presentation permitted content belonging to the theme. A menu screen (for example, FIG. 17) for canceling the theme registration indicating that has been permitted is selected (step S52).

  Note that if the user's second interest level for the theme exceeds a given second interest level threshold value in a given period, the interest level evaluation unit 116 determines for the next given period, The user's second degree of interest in the theme may be reset.

  In step S51, specifically, the interest level evaluation unit 116 acquires the second interest level of the user for the theme of the presentation permitted content based on the presentation permitted content from the interest level information storage unit 126, and the given second Are obtained from the storage unit 120. For example, the second degree of interest of the user with respect to theme 2 (food habit improvement) is “0”. The degree-of-interest evaluation unit 116 determines whether or not the second degree of interest of the user with respect to the theme of the presentation-permitted content based on the presentation-permitted content exceeds a given second degree-of-interest threshold for a given period. For example, a given period is one week. The given second interest level threshold is, for example, “10”. If the second interest level of the user with respect to the theme of the presentation permitted content based on the presentation permitted content does not exceed the given second interest level threshold value in the given period, the interest level evaluation unit 116 determines that the presentation permitted content is The presentation control unit 114 is notified that the second interest level of the user with respect to the theme of the presentation-permitted content based on the second interest degree threshold does not exceed the given second interest degree threshold.

  For example, the second degree of interest of the user with respect to theme 2 (meal habit improvement) is “100”, and the second degree of interest of the user with respect to the theme of the presentation-permitted content based on the presentation-permitted content during a given period. When the given second interest level threshold is exceeded, the interest level evaluation unit 116 may reset the second interest level “100”, and the presentation permission based on the presentation-permitted content in the next given period. It may be determined whether the user's second level of interest for the content theme exceeds a given second level of interest threshold.

  In step S52, specifically, the presentation control unit 114 displays a menu screen (for example, FIG. 17) for canceling theme registration indicating that the user has permitted the presentation of the presentation permitted content belonging to the given theme. Read from the information storage unit 122 and select the menu screen. Note that the content presentation unit 140 presents a menu screen for canceling theme registration to the user in response to this selection. When the user requests cancellation of theme registration, the theme registration processing unit 112 cancels theme registration of the corresponding theme from the theme registration information. In addition, the presentation permission content selection part 110 cannot select the presentation permission content which belongs to the canceled theme.

  When the presentation permission content selection unit 110 can select the presentation permission content belonging to the given theme as shown in step S3 of FIG. 4A, the interest level evaluation unit 116 in step S51 of FIG. , It may be determined whether, during a given time period, the user's second degree of interest for a presentation-permitted content theme based on the presentation-permitted content exceeds a given second degree-of-interest threshold. For example, the presentation permission content selection unit 110 can select only the presentation permission content belonging to the theme 2 (food habit improvement), and the presentation permission content selection unit 110 selects the presentation permission content belonging to the theme 1 (walking amount increase). When the selection cannot be made, the interest level evaluation unit 116 determines whether or not the user's second interest level for only theme 2 (meal habit improvement) exceeds a given second interest level threshold value in a given period. can do.

7). Achievement Level Evaluation Operation In FIGS. 18A and 18B described above, the process of reconfirming (verifying) the interest level of the presentation permitted content has been described. When the presentation permission content induces the user's behavior, for example, the user is interested in the presentation permission content, but the user's motivation may be reduced depending on the implementation status of the user. In order to support the user's appropriate behavior, the present embodiment can adopt an achievement evaluation operation based on the presentation permitted content. The achievement level evaluation operation can be divided into an achievement level update operation and an achievement level determination operation.

An example of the achievement level update operation of the present embodiment will be briefly described with reference to FIGS. 19 (A), 19 (B), 20 (A), and 20 (B). FIGS. 19A, 19B, and 20A show examples of presentation by the content presentation unit. FIG. 20B shows an example of a table for converting the response to the presentation permitted content into the achievement level.
FIG. 19A shows a situation where the user is about to set the target value of theme 1 (walking amount increase) via the operation unit 160 or the sensor. FIG. 19B shows a situation where the user is about to input the implementation status of theme 1 (walking amount increase) via the operation unit 160 or the sensor.
In FIG. 20 (A), after the user reacts to the presentation permission content as shown in C1 in FIG. 14 (B) (let's get off at AB station and take a walk), then in FIG. 20 (A) at D1 Situation in which the user is responding (obeying) to the next permitted content belonging to theme 1 (increase in walking amount) (exit the south gate and proceed on ABC street) via the operation unit 160 or sensor Is shown. In FIG. 20B, when the instruction of the presentation permitted content in FIGS. 14B and 20A corresponds to the walk course 1, the evaluation point for the completion (obedience) of the walk course 1 is 1000.

  Next, an example of achievement level update operation of the present embodiment will be described with reference to FIGS. 21 (A) and 21 (B). FIG. 21A is a flowchart regarding the update of the achievement level evaluation unit, and FIG. 21B is an explanatory diagram of the update method of the achievement level evaluation unit.

  First, the reaction determination unit 105 determines whether or not the user has reacted to the presentation permitted content (step S61). When the user responds to the presentation permission content, the achievement level evaluation unit 118 evaluates the user's achievement level with respect to the theme of the presentation permission content (step S62). And the achievement level evaluation part 118 accumulate | stores the user's achievement level with respect to the theme of a presentation permission content (step S63). The presentation control unit 114 may select the presentation permitted content based on the achievement level of the user.

  In step S61, specifically, the reaction determination unit 105 determines whether or not the operation information from the operation unit 160 indicates that the user has reacted to the presentation permitted content. The reaction determination unit 105 further determines whether or not the operation information represents an implementation status. The reaction determination unit 105 may use sensor information from the wearable sensor 150 (for example, the line-of-sight sensor 562, the GPS sensor 550, etc.) instead of the operation information from the operation unit 160. The presentation control unit 114 notifies the reaction determination unit 105 that the presentation permitted content including the implementation status is selected (determined), and the reaction determination unit 105 receives the operation information and the sensor information based on the notification. It is determined whether or not it represents that the content has been permitted to be presented, and further whether or not the operation information and sensor information represent the implementation status.

  For example, the reaction determination unit 105 determines that the operation information or the sensor information represents selection of an implementation status included in the presentation permitted content selected (determined) by the presentation control unit 114 (for example, FIG. 19B). Thus, the reaction determination unit 105 determines that the operation information or sensor information represents that the user has reacted to the implementation status included in the presentation permitted content.

  In step S62, specifically, the achievement level evaluation unit 118 evaluates the user's achievement level for the theme based on the implementation status of the presentation permitted content that the user has reacted to. The presentation control unit 114 notifies the achievement degree evaluation unit 118 of the presentation permission content selected (determined), and the achievement degree evaluation unit 118 determines the user's response to the theme based on the presentation permission content from the presentation control unit 114. Evaluate achievement. The presentation control unit 114 may notify the achievement level evaluation unit 118 of the ID of the presentation permitted content selected (determined). The achievement level evaluation unit 118 refers to the content information storage unit 122 and performs presentation control. The implementation status of the presentation permitted content corresponding to the ID of the presentation permitted content from the unit 114 may be acquired, and the achievement level of the user with respect to the theme may be evaluated based on the acquired implementation status.

  In step S62, specifically, the achievement level evaluation unit 118 uses the target value for each theme stored in the storage unit 120 (for example, FIG. 19A) to execute the presentation permitted content that the user has reacted to. The situation is converted (evaluated) into the achievement level of the user for the theme. For example, when the target value of theme 1 (increase in walking amount) is “63,000 steps per week” and the implementation status of a certain day is “3,000 steps per day”, the achievement evaluation unit 118 Can be evaluated (calculated) with a degree of achievement of 3,000 / (63,000 / 7) × 100 = 33 [%].

  Achieved when the user responds (obeyed) to a series of a plurality of presentation-permitted contents such as FIG. 14B and FIG. 20B, and the implementation status of one time is “completion of walk course 1”. The degree evaluation unit 118 may evaluate 1000 steps as an intermediate achievement level using a table (eg, FIG. 20B) that stores evaluation points. At this time, an expression for calculating an intermediate degree of achievement may be used. In this case, the achievement level [%] may be evaluated by adding intermediate achievement levels in one day.

  In step S63, specifically, the achievement level evaluation unit 118 accumulates the achievement level in units of one day in the achievement level information storage unit 128. The achievement level evaluation unit 118 may accumulate an average achievement level obtained by averaging a plurality of achievement levels. The presentation control unit 114 may select the presentation permitted content based on the achievement level, the intermediate achievement level, or the average achievement level.

When the storage unit 120 stores the target value for the theme as shown in FIG. 19A, in step S61, the reaction determination unit 105 determines whether the user has reacted to the implementation status of the presentation permitted content. be able to.
Next, an example of the achievement level determination operation according to this embodiment will be briefly described with reference to FIGS. 22 (A), 22 (B), and 23. FIG. 22A and 22B show examples of setting the achievement threshold. FIG. 23 shows a presentation example of the content presentation unit.

  For example, as shown in FIG. 22A, if the achievement level of the theme does not exceed the achievement level threshold value in a given period, the content presentation unit 140 permits presentation belonging to the theme as shown in FIG. A menu screen for canceling content theme registration can be presented. For example, as shown in FIG. 22B, when the achievement level of the theme exceeds the achievement level threshold value in a given period, as shown in FIG. 23, the content presentation unit 140 displays the presentation permitted content belonging to the theme. A menu screen can be presented to continue the theme registration.

  Next, an example of the achievement level determination operation of the present embodiment will be described with reference to FIGS. 24 (A) and 24 (B). FIG. 24A is a flowchart regarding the determination of the achievement level, and FIG. 24B is an explanatory diagram of the determination method of the achievement level.

  First, the achievement level evaluation unit 118 determines whether or not the user's achievement level with respect to the theme of the presentation permitted content exceeds a given achievement level threshold during a given period (step S71). Next, when the achievement level of the user with respect to the theme does not exceed the given achievement level threshold during the given period, the presentation control unit 114 has permitted the presentation of the presentation permission content belonging to the given theme. A menu screen (for example, FIG. 17) for canceling the theme registration representing is selected (step S72). When the achievement level of the user with respect to the theme exceeds the given achievement level threshold value during the given period, the presentation control unit 114 indicates that the user has permitted the presentation of the presentation permitted content belonging to the given theme. Is selected (for example, FIG. 23) (step S73).

  In step S <b> 71, specifically, the achievement level evaluation unit 118 acquires all achievement levels in a given period from the achievement level information storage unit 128 and acquires a given achievement level threshold value from the storage unit 120. The achievement level evaluation unit 118 determines whether all achievement levels in a given period exceed a given achievement level threshold in a given period. For example, a given period is 4 weeks. The given achievement threshold is, for example, “100 [%]”. The achievement level evaluation unit 118 notifies the presentation control unit 114 of the determination result of the achievement level evaluation unit 118.

  In step S72, specifically, the presentation control unit 114 displays a menu screen (for example, FIG. 17) for canceling the theme registration indicating that the user has permitted the presentation of the presentation permitted content belonging to the given theme. Read from the information storage unit 122 and select the menu screen. Note that the content presentation unit 140 presents a menu screen for canceling theme registration to the user in response to this selection.

  In step S73, specifically, the presentation control unit 114 displays a menu screen (for example, FIG. 23) for continuing theme registration indicating that the user has permitted the presentation of the presentation permitted content belonging to the given theme. Read from the content information storage unit 122 and select the menu screen. Note that the content presentation unit 140 presents a menu screen for continuing theme registration to the user in response to this selection.

  When the achievement information storage unit 128 accumulates achievements in a given period as shown in step S63 of FIG. 21A, FIG. 22A, and FIG. The determination unit 105 can determine whether all achievements in a given period exceed a given achievement threshold in a given period.

9. Specific Operation Example Next, a specific operation example of the present embodiment will be described. In the following, an example in which the first system configuration of FIG. 2 is used will be described, but the same operation is performed when the second system configuration of FIG. 25 is used. Further, a part of the first system configuration and a part of the second system configuration may be combined.

  When the user presses the power-on button 160, the processing unit 102 of the portable electronic device 100 is activated by a power-on signal. When the theme registration processing unit 112 of the processing unit 102 is activated, the theme registration processing unit 112 refers to the theme registration information stored in the storage unit 120 (step S1 in FIG. 4A). For example, as shown in FIG. 27A, the flag of theme registration information is in a state where theme registration of theme 1 (increase in walking amount) and theme 2 (improvement in eating habits) is not performed (“0”). In other words, the presentation-permitted content selection unit 110 cannot select the presentation-permitted content when the theme registration of another theme is not performed (“0”). As shown in FIG. 3A, when only the base content selection unit 108 can select the base content, the presentation control unit 114 selects at least one base content from the base content selection unit 108 (see FIG. 3A). 6 (A), step S14), the content presentation unit 140 presents at least one selected base content (step S15).

  Each of the plurality of base contents stored in the content information storage unit 122 can have genre information. For example, as shown in FIG. 8A, each base content has information on any one of genres 1 to 28. In addition, each base content includes user status (TPof) type information (for example, 1. “Home in the morning”, 2. “Working in the morning”, 3. “Morning at work”, 4. “Lunch break at work” , 5. “Afternoon at work,” 6. “Returning home after leaving the office”, 7. “Home at night”,.

  For example, the situation estimation unit 106 estimates that the user is at home at 7:00 am as the user situation (TPOf) (step S12 in FIG. 6A). Moreover, the situation estimation part 106 can estimate Type 1 (home in the morning) as a user's situation type. The base content selection unit 108 selects at least one base content that matches the estimated user's situation from the plurality of base contents stored in the content information storage unit 122 (step S13). For example, the base content selection unit 108 selects three base contents. One of the three base contents is, for example, “What is the weather today?”. The presentation control unit 114 selects the three base contents as they are (step S14), generates screen data in accordance with the specifications of the content presentation unit 140, and the content presentation unit 140 is configured with 3 as shown in FIG. One base content is presented (step S15). However, in the example of FIG. 7A, presentation permission content is also presented, but when the presentation permission content selection unit 110 cannot select the presentation permission content, only three base contents are presented.

  For example, the user operates the cross key 160 to control the pointer shown on the screen of the content presentation unit 140 and to set the pointer to one of the three base contents, “What is the weather today?” When the user clicks the cross key 160, the reaction determination unit 105 of the situation estimation unit 106 determines that the user has selected “What is the weather today?” (Step S21 in FIG. 9A). In response to the user's reaction, the base content selection unit 108 displays detailed content representing the continuation of the base content (what is today's weather?) (Today's weather is rainy. The probability of precipitation in the morning in Tokyo is 30%. (The probability of precipitation in the daytime is 70%.) Is selected, and the content presentation unit 140 displays a detailed screen as shown in FIG. Is 30% .The probability of precipitation in the day is 70%.

  When the reaction determination unit 105 of the situation estimation unit 106 determines that the user has selected “What is the weather today?” (Step S21), the interest level evaluation unit 116 determines the response to the theme based on the base content that the user has reacted to. The degree of interest of the user is evaluated (step S22). When the genre of the base content (what is the weather today) corresponds to the genre 2 as shown in FIG. 8A, the evaluation point for the theme 1 (increase in walking amount) is “0”, and the theme 2 ( The evaluation point for “eating habit improvement” is also “0”. The interest level evaluation unit 116 reads the user's interest level for the theme 1 and the theme 2 before the evaluation from the interest level information storage unit 126. For example, when the degree of interest of the user with respect to theme 1 and the degree of interest of the user with respect to theme 2 are both “0”, the interest level evaluation unit 116 sets the degree of interest of the user with respect to theme 1 (increase in walking amount) to “0”. (= “0” + “0”) and the user's interest level for theme 2 (food habit improvement) is updated to “0” (= “0” + “0”) (FIG. 9A). Step S23).

  Thereafter, the presentation control unit 114 repeatedly selects three new base contents (step S14 in FIG. 6A), and the content presentation unit 140 also repeats the presentation of three new base contents (step S15). If there is base content indicating interest, the user reacts to the base content, and the interest level evaluation unit 116 repeats updating the user's interest level for themes 1, 2,... Based on the base content (FIG. 9). (A) Step S23).

  At some point, for example, as shown in FIG. 10, when the user's interest in the theme 2 (eating habit improvement) increases, the interest level evaluation unit 116 gives the user's interest in the theme 2 (eating habit improvement) to a given level. It is determined that the interest level threshold is exceeded (step S31 in FIG. 12A).

  According to the conversion table shown in FIG. 8 (A), the theme 2 can be used not only when the user reacts to the base content belonging to the genre 19 (diet) but also to the base content belonging to the genre 4 (sport watching). The user's interest in (food habit improvement) is increased. In other words, the information presentation system is not limited to the genre 19 (diet) that is directly related to the theme 2 (eating habit improvement), but the themes such as the genre 4 (watching sports) that the user is supposed to spend at home. Genres 4, 6, 7, 8, 11, 12, and 15 indirectly related to 2 (eating habit improvement) are also evaluated. Thus, the information presentation system can obtain information (food habits improvement) that may give a new awareness to the user.

  The conversion table shown in FIG. 8A can include a negative numerical value as an evaluation point, as in genre 5 (sport practice) of theme 1 (walking amount increase). Genres 4, 6, 7, 8, 11, 12, 15 where the reaction to genre 5, 13, 14, 24, which the user is supposed to spend outside the home, is estimated to be the user will spend at home If there are more responses to the information, the information presentation system can determine that the user is not interested in theme 1 (increase in walking amount).

  When the user's interest level for the theme 2 (food habit improvement) exceeds a given interest level threshold, the presentation control unit 114 obtains the presentation permission of the presentation permission content belonging to the theme 2 (food habit improvement) from the user. A menu screen (for example, FIG. 3B) is selected (step S32 in FIG. 12A). When the user responds to “YES”, the theme registration processing unit 112 recognizes the theme registration of theme 2 (food habit improvement) (step S1 in FIG. 4A), and the presentation permitted content selection unit 110 displays the theme. The presentation permitted content belonging to 2 can be selected (step S2). The reaction determination unit 105 updates the theme registration information stored in the storage unit 120. As shown in FIG. 27B, the updated flag of the theme registration information is the theme registration of theme 2 (food habit improvement). Is in a state (1).

  When the presentation-permitted content selection unit 110 can select the presentation-permitted content that belongs to theme 2, the presentation-permitted content selection unit 110 displays a menu screen (see FIG. 19A) for obtaining the target value of theme 2. Enter the target weight after 3 months: 55kg, 60kg, 65kg.) For example, “Do you take notes of meal contents? YES, NO”, “Please enter today's weight.”, “Today is vegetable-centric. "Let's eat a meal.", "Let's refrain from meat-centered meals today."

  Thereafter, when the user's interest level for the theme 1 (increase in walking amount) also exceeds a given interest level threshold, the presentation control unit 114 selects, for example, the interest confirmation content shown in FIG. The history information storage unit 124 can store the user's past action history (history information storing the estimated user status), and the reaction determination unit 105 can determine the user's stay location and the status five minutes ago. The current stay location estimated by the estimation unit 106 is compared. If the two match, the reaction determination unit 105 can determine that the user has reacted to the interest confirmation content (step S33 in FIG. 12A). And the presentation control part 114 selects the menu screen for performing theme registration of the theme 1 (walking amount increase) (step S32). When the user responds to “YES”, the theme registration processing unit 112 recognizes theme registration of theme 1 (increase walking amount) (step S2 in FIG. 4A), and the presentation permitted content selection unit 110 displays the theme. The presentation permitted content belonging to 1 can also be selected (step S3). The reaction determination unit 105 updates the theme registration information stored in the storage unit 120. As shown in FIG. 27C, the updated flag of the theme registration information indicates the theme registration of theme 1 (increase in walking amount). Is also performed ("1").

  As described above, in the present embodiment, when the theme registration indicating that the user has permitted the presentation of the presentation permitted content belonging to the given theme is performed, the presentation permitted content selection unit 110 sets the given theme as the given theme. Select the presentation-permitted content to which it belongs. Since the user's will is confirmed, even if the presentation permission content induces the user's behavior or the like, for example, the user is unlikely to receive psychological pressure.
