  The present invention relates to a request presenting apparatus, a request presenting system, a request presenting method, and a request generating method, for example, a request presenting apparatus and a request presenting system capable of transmitting a request according to the intention of a target person who is poor in ability to communicate to others. The present invention relates to a request presentation method and a request generation method.

Conventionally, even if patients with ALS (Amyotrophic Lateral Sclerosis) or muscular dystrophy have lost their ability to communicate by speaking or giving instructions on the dial, they are willing to support communication to others A transmission support apparatus is known (see, for example, Patent Document 1).
In the communication support apparatus described in Patent Document 1, the display device displays a message menu in which a list of a plurality of pre-registered messages is set, and sequentially selects the plurality of messages (certifiable items) ( Highlight). When the user performs a spontaneous action such as reading a character at the selected location, the brain activity current in the frontal region generated by the spontaneous action is detected. Thereby, the electroencephalogram signal component (β wave) based on the electroencephalogram current is processed, and if it is determined that the electroencephalogram signal component should turn on the electroencephalogram switch, the message at the selected location by the electroencephalogram switch is displayed to the user. As a message.

Japanese Patent No. 2899194

  The intention transmission support apparatus described in Patent Document 1 is configured to notify a pre-registered message based on the user's brain wave, but it is difficult for the user to freely output a β wave. For this reason, the said communication support apparatus has the problem that it is difficult to use and it is difficult to use.

  The present invention aims to solve at least a part of the above-described problems, and is a request presenting apparatus, a request presenting system, a request presenting method, and a request generating method capable of transmitting request items according to the intention of the target person Is one of the purposes.

  The demand presentation device according to the first aspect of the present invention includes a biological information acquisition unit that acquires biological information of a target person, a detection time acquisition unit that acquires a detection time when the biological information is detected, and the acquired And an information presenting unit that presents request information indicating a request matter of the subject according to the intention of the subject based on the biological information and the detection time.

Here, the desired items that the subject wants to respond to can be classified to some extent according to the time, and can be further classified based on the biological information of the subject.
Based on this, in the first aspect, the request item based on the biological information detected from the target person by the information presentation unit and the detection time at which the biological information is detected is a request according to the intention of the target person. Presented as a matter. Thereby, the subject matter of the subject can be transmitted to the person who performs the care and watching of the subject. Therefore, it is possible to transmit a request item according to the intention of the subject who cannot communicate the intention to the other person such as a caregiver.

In the first aspect, based on the acquired biological information, a state estimation unit that estimates the mental state of the subject, and the request information based on the estimated mental state and the detection time. It is preferable to have an information generation unit that generates and presents the request information to the information presentation unit.
The mental state represents a mental state of the subject such as uncomfortable or comfortable.
Here, for example, since the heart beat is closely related to the autonomic nerve (sympathetic nerve and parasympathetic nerve), the mental state of the subject is determined from the pulse wave and electrocardiogram derived from the heart beat. Can be estimated. In addition, since the body temperature and blood pressure also change according to the fluctuation of the spirit, the mental state of the subject can be estimated from these biological information.
For this reason, according to the said structure, an information generation part produces | generates the request information which shows the subject matter of the said subject based on the mental state of the subject estimated by the state estimation part, and the said detection time. Therefore, the precision of the request according to the mental state of the subject can be increased.

In the first aspect, the state change determination unit that determines whether or not the mental state has changed from a comfortable state that the subject feels comfortable to an unpleasant state that makes the subject feel uncomfortable, and the state change determination unit causes the discomfort A change gradient determination unit that determines whether or not the change gradient of the mental state is higher than a predetermined value when it is determined that the state has changed, and the information generation unit is When it is determined that the change gradient of the mental state is higher than the predetermined value, it is preferable that the request information is generated.
Here, when the target person is in a comfortable state, there are not many requests that the target person wants to do, and when the target person is in an uncomfortable state, the request is generated. To do. On the other hand, when changing from an unpleasant state to a comfortable state, the cause that the subject feels uncomfortable and dissatisfied is often resolved, and when the subject's state has not changed much, the subject is It can be determined that the urgency of any treatment that should be done is not so high.
Based on this, according to the above configuration, when the determination is made by the state change determination unit and the change gradient determination unit, the subject is in an uncomfortable state and desires a prompt treatment (implementation of requested items) In addition, it is possible to present the request of the target person to other persons such as caregivers. Therefore, the convenience of the request presentation device can be improved.

In the first aspect, the information processing unit includes a storage unit that stores a plurality of candidates for the desired matter, and the information generation unit includes the plurality of candidates stored in the storage unit at the mental state and the detection time. It is preferable to extract a candidate according to the request and generate the request information including the extracted candidate.
According to the above configuration, a plurality of candidates for desired items are stored in the storage unit, and the information generation unit generates request information including candidates according to the mental state and detection time of the target person with reference to the storage unit Therefore, it is possible to extract and present the subject matter of the target person relatively easily. Moreover, since such a requirement can be set according to a subject, the requirement suitable for a mental state of a subject can be shown reliably.

In the first aspect, the storage unit stores each of the plurality of candidates in association with a time zone in which the candidate is likely to be desired, and the information generation unit is stored in the storage unit. Among the plurality of candidates, the candidates are stored in association with the time zone including the detection time, and the candidates corresponding to the mental state estimated by the state estimation unit are extracted to generate the request information It is preferable.
According to the above configuration, the information generation unit refers to the storage unit, extracts candidates corresponding to the mental state of the subject from the candidates associated with the time zone including the detection time, and Generate request information. According to this, as described above, since the subject matter of the subject can be classified to some extent according to the time zone, a candidate of the matter desired along the current mental state of the subject can be presented.

In the first aspect, the storage unit stores each of the plurality of candidates, the time zone, and the change gradient of the mental state when the candidate is desired, and stores the information generation unit Preferably, among the extracted candidates, the request information in which a candidate having a high degree of matching with the mental state and the change gradient of the mental state is preferentially presented is generated.
Here, the change gradient of the mental state is also an index when the desired items are classified. For example, if the subject wants to wipe his / her face, the mental state gradually changes from a comfortable state to an uncomfortable state, but the subject wants to remove foreign matter such as the throat. In some cases, the change to an uncomfortable state occurs abruptly.
Based on this, according to the above configuration, candidates based on the mental state change gradient as well as the mental state change gradient are extracted from the storage unit, and the degree of fitness with the mental state and the change gradient is high. Presentation information in which candidates are presented with priority is generated. Accordingly, it is possible to present a request item suitable for the current state of the target person, and it is possible to quickly grasp the request item most suitable for the state of the target person.

In the first aspect, it is preferable that the state change determination unit determines the mental state at a predetermined time interval.
As the predetermined time interval, for example, an interval of 1 minute or more can be exemplified.
According to the above configuration, since the state change determination unit determines the mental state at predetermined time intervals, it is possible to suppress the occurrence of frequent determination processing and increase in power consumption. Accordingly, the request presentation device can be configured by a portable terminal device.

In the first aspect, it is preferable that the state estimation unit digitizes the mental state based on the biological information.
In addition, as a numerical value showing a mental state, the numerical value which changes from the state in which it feels most comfortable to the state in which it feels most uncomfortable can be illustrated as the said numerical value increases or decreases.
According to the above configuration, the state estimation unit changes the mental state by quantifying the mental state of the subject according to, for example, the degree of the comfortable state and the degree of discomfort that the subject feels. It is also possible to make it easier to grasp the transition of the mental state. Therefore, it is possible to easily present the request information according to a change in the mental state of the subject.

In the first aspect, it is preferable that the biological information includes at least one of a heartbeat and a pulse.
Here, since the heart beat is closely related to the autonomic nerve as described above, the mental state of the subject can be grasped from the pulse wave and the electrocardiogram derived from the heart beat.
Based on this, according to the above configuration, the mental state of the subject can be estimated more accurately than in the case where the state of the subject is grasped from the biological information other than the heartbeat and the pulse. Accordingly, it is possible to more accurately present the desired items according to the intention of the target person.

Remember.

[Configuration of state estimation unit]
The state estimation unit 455 estimates the mental state of the subject SB based on the detection result acquired by the information acquisition unit 454, and quantifies the mental state.
The mental state is an index that represents the degree of comfort and discomfort of the subject SB, and is set based on the biological information and body movement information (particularly biological information). In the present embodiment, the mental state is represented by a numerical value calculated based on a calculation formula to be described later, in which the excited state, the arousal state, and the fatigue state of the subject SB are digitized.

FIG. 6 is a diagram illustrating the excited state, the awakened state, and the fatigued state of the subject SB. In FIG. 6, A to C indicate the excitement state, the awakening state, and the fatigue state of the subject SB, respectively, in a numerical range of −5 to +5.
Here, the pulsation of the heart, that is, the heartbeat is affected by autonomic nerves (sympathetic nerve and parasympathetic nerve). For this reason, the activity state of the autonomic nerve can be estimated from the state of the pulse closely related to the heartbeat, and as a result, the excitement state, the arousal state, and the fatigue state of the subject SB can be quantified as shown in FIG.

The excited state of the subject SB is estimated based on the transition of the pulse rate. For example, when the pulse is changing at a high value, it can be estimated that the subject SB is in an excited state or a tension state. Examples of such a state include a state of high motivation such as watching or feeling a person who is currently interested. On the other hand, for example, when the pulse is stable at a low value, it can be estimated that the subject SB is in a relaxed state.
Specifically, the state estimation unit 455 divides the time change of the peak-to-peak distance (RR interval) of the pulse wave signal into a low frequency component LF and a high frequency component HF by performing frequency analysis (FFT), and these low frequencies. Based on the ratio of the component LF and the high frequency component HF, the excitement state of the subject SB is digitized by a numerical value in the range of −5 to +5. In this numerical range, “0” indicates a neutral point between relaxation, excitement, and tension, and a numerical value in the range of −5 to 0 indicates a degree of relaxation with −5 being the most relaxed state. The numerical value in the range of ˜ + 5 indicates the degree of excitement and tension with +5 being the most excited or tense state.

  Note that there are cases where the actual mental state of the subject SB cannot always be accurately represented only by the numerical value of the excited state. That is, even if it is numerically determined to be excited or relaxed, the actual mental state of the subject SB may not correspond to the state. For this reason, in this embodiment, only the excited state of the subject SB is not determined as the mental index of the mental state, but the mental state is comprehensively determined in consideration of other mental indexes (arousal state and fatigue state). doing.

  The awakening state of the subject SB is estimated based on the height of the fluctuation average value of the pulse rate calculated based on the pulse wave signal. For example, when the pulse rate is close to the basal pulse rate (resting pulse rate) and the fluctuation average value of the pulse rate is low, it is estimated that the subject SB is in deep sleep. Moreover, when the pulse rate is the pulse rate at the time of awakening, it is possible to determine the awakening level of the subject SB based on the fluctuation average value of the pulse rate. Based on such sleep depth and arousal level, the state estimation unit 455 digitizes the awake state of the subject with a numerical value in the range of −5 to +5. In this numerical range, “0” indicates a neutral point between sleep and awakening, and a numerical value in a range of −5 to 0 indicates a degree of sleep (depth) where the deepest sleep state is −5. The numerical value in the range of 0 to +5 indicates the degree of arousal in which the most awake state is +5.

The fatigue state of the subject person SB is estimated from the transition of the pulse rate calculated based on the pulse wave signal. For example, the physical strength and physical condition of the subject SB can be estimated from changes in basal metabolic rate based on calorie consumption calculated from the time integral value of the pulse rate, average daily pulse rate, and basal pulse rate. And the state estimation part 455 digitizes the fatigue state of the subject SB with a numerical value in the range of −5 to +5 based on these numerical values. In this numerical range, “0” indicates the average physical state of the subject SB, and the numerical values in the range of −5 to +5 indicate the state with the highest fatigue level as −5 and the state with the lowest fatigue level. The degree of fatigue is shown as +5.
In the present embodiment, the information processing device 4 can acquire the body motion information of the subject SB detected by the body motion information detection device 3. For this reason, the state estimation unit 455 uses the body motion information to improve the accuracy of the fatigue state of the subject SB.

Then, the state estimation unit 455 digitizes the mental state of the subject SB based on the numerical value of each state and the exercise intensity indicating the motion of the subject SB. Specifically, the state estimation unit 455 substitutes a numerical value into the following formula (1) to digitize the index value X for digitizing the mental state.
In this formula (1), A to C are the numerical values indicating the excited state, the arousal state, and the fatigue state, respectively, and α, β, and γ are coefficients, and can be appropriately adjusted according to the subject SB. . M (I) is a value indicating the exercise intensity of the exercise performed by the subject SB.
In this embodiment, since the excitement state, the arousal state, and the fatigue state of the subject SB are quantified, in the formula (1), A to C are included, but instead of any of these, Alternatively, in addition, when other mental indicators are included, coefficients and values corresponding to the other mental indicators are set in parentheses.

[Equation 1]
X = (αA + βB + γC) + M (I) (1)

FIG. 7 is a graph used when quantifying the exercise intensity of the exercise performed by the subject SB. In FIG. 7, the horizontal axis indicates exercise intensity I (Mets and the like), and the vertical axis indicates a motion state function M (I) indicated by a numerical range of −5 to +5.
As shown in the above equation (1), not only the above three mental states but also the exercise state (exercise intensity) of the subject SB is considered in the estimation of the mental state. This is because even if the mental state is the same, if the exercise intensity increases, the influence of the mental state on the pulse and the heart rate decreases. Based on this, the exercise intensity of the exercise performed by the subject SB is represented by the function M (I) shown in FIG. 7, and the value of the function M (I) is used for estimation and quantification of the mental state. Yes. Such an exercise state of the subject SB is grasped based on the body motion information acquired from the body motion information detection device 3.
In addition, in the index of exercise intensity in the present embodiment, M (I) when the body does not move much, such as “sleeping sideways” or “sitting (raising the upper body)”, It is lower than M (I) in other motion states. Then, M (I) is maximized when “walking”, and M (I) when “running (sporting)” is lower than M (I) when “walking” . The numerical range of the exercise intensity is a numerical range of −5 to +5 according to the mental state.

In the example shown in FIG. 6, the excited state (A) is “3”, and the arousal state (B) and the fatigue state (C) are “2”, respectively. Here, if the coefficients α, β, and γ are all set to “1” and the subject SB is sitting, M (I) is “0”, so the index value X is “7”. .
Similarly, in the case of other biological information (for example, blood pressure and body temperature) different from the heartbeat and the pulse, the above A to C are obtained by estimation based on the biological information. When a plurality of pieces of biological information are obtained, for example, A, B, and C are obtained from the pulse or heartbeat, and A ′, B ′, and C ′ are obtained from other biological information. An index value X is obtained.

Then, the state estimation unit 455 represents the mental state of the subject SB with a numerical value of 1 to 5 based on the index value X. In this numerical range, “3” is a neutral point of comfort and discomfort, and a numerical value in the range of 1 to less than 3 indicates the discomfort level of the subject SB with 1 being the state that the subject SB feels most uncomfortable. The numerical value in the range of more than 3 and 5 or less indicates the comfort level of the subject SB with 5 being the state that the subject SB feels most comfortable.
Specifically, the state estimation unit 455 sets the numerical value indicating the mental state of the subject SB to “1” when the index value X is included in the first range, and when the index value X is included in the second range. “2”, “3” when included in the third range, “4” when included in the fourth range, and “5” when included in the fifth range. These first to fifth ranges are set according to the index value X in a state in which the subject SB feels comfortable and uncomfortable.
In this way, the state estimation unit 455 digitizes the mental state of the subject SB.

[Configuration of state change determination unit]
Returning to FIG. 5, the state change determination unit 456 traces the transition of the numerical value of the mental state estimated by the state estimation unit 455 at a predetermined interval, and determines whether or not the numerical value is 3 or less. To do. In other words, the state change determination unit 456 determines whether or not the mental state in which the subject SB feels uncomfortable has been reached. Note that the interval at which the state change determination unit 456 executes the determination process is a time interval at which the change in the mental state of the subject SB can be grasped is the reception period of the detection results from the detection devices 2 and 3. Is set based on For example, when the detection results are received from the detection devices 2 and 3 every other minute, the state change determination unit 456 determines the numerical value of the mental state every other minute.

[Configuration of change gradient judgment unit]
FIG. 8 is a diagram illustrating the transition of numerical values indicating the mental state of the subject person SB. The horizontal axis in FIG. 8 indicates the passage of time, and the vertical axis indicates a numerical value indicating the mental state.
The change gradient determination unit 457 functions when the state change determination unit 456 determines that the numerical value of the mental state is a value of 3 or less. The change gradient determination unit 457 determines whether or not the change gradient of the numerical value is equal to or less than a predetermined value.
Here, the numerical value of the mental state digitized by the state estimation unit 455 varies with time as shown in FIG. That is, the value of the function f (t) indicating the mental state increases or decreases with time t. For example, if the desire for a meal increases, the numerical value of the mental state decreases to a numerical value range indicating “discomfort”, and if a meal is provided, the numerical value increases to “comfortable” It is a numerical value in the numerical range indicating. In such a change in numerical value, when the numerical value rapidly decreases, it is determined that the demand and desire of the subject SB are rapidly increasing. That is, when the change gradient of the numerical value of the mental state is a negative value and smaller than the predetermined value, it is determined that the desire and desire of the subject SB are rapidly increasing.

For this reason, the change gradient determination unit 457 determines whether or not the request and desire of the subject SB are rapidly increasing, that is, the change gradient of the numerical value of the mental state in order to determine the urgency of the request and desire. It is determined whether or not the determination condition that (slope) is a negative value and smaller than a predetermined value is met.
In this determination process, when it is determined that the determination condition is satisfied (for example, at the times t1, t4, and t6 in FIG. 8), the request and desire of the target person SB are rapidly increasing. And it is judged that the urgency of desire is increasing. Such requests include “urination” in “excretion”, “problem with tube” in “meal”, and the like.

On the other hand, when it is determined that the determination condition is not met, the change gradient is a negative value but is determined to be smaller than the predetermined value (for example, at times t2 and t5 in FIG. 8). Therefore, it is determined that the request and desire of the target person SB are not so high, and the urgency of the request and desire is low.
On the other hand, in the case where it is determined that the determination condition is not met, when it is determined that the change gradient is not a negative value (for example, at time t3 in FIG. 8), the mentality of the subject SB The condition is judged to be comforting from discomfort. Even in this case, it is determined that there is no urgent need to deal with the subject person SB.
In this way, the change gradient determination unit 457 determines whether or not it is necessary to urgently take any action on the subject SB.

  As described above, when the state change determination unit 456 determines that the numerical value indicating the mental state is 3 or less, and the change gradient determination unit 457 determines that the determination condition is satisfied, the subject SB is uncomfortable. It shows a state in which the desire to respond to any request for a particular state is increasing. In other words, the state change determination unit 456 and the change gradient determination unit 457 determine whether or not the desire is increased in the target person SB.

[Configuration of information generator]
Returning to FIG. 5, the information generation unit 458 generates display information set on the state presentation screen S <b> 1 (see FIG. 9) that presents a numerical value indicating the mental state of the subject calculated by the state estimation unit 455. . The contents of this display information will be described together with the status presentation screen S1.

Generate request information. This request information is information including request items according to the request and desire of the target person SB.
Specifically, the information generation unit 458 first detects the date and time when the detection result serving as the basis of the numerical value indicating the mental state when the change gradient determination unit 457 determines that the determination condition is satisfied (particularly, the date and time) Time). Since this date and time is stored in the storage unit 44 in association with the detection result, the information generation unit 458 refers to the storage unit 44 and acquires the date and time.
Then, the information generation unit 458 refers to the intention database that is also stored in the storage unit 44 and extracts and acquires the detailed items whose acquired date and time are included in the time zone. Thereby, the request matter (detail item) which the subject SB currently requests is acquired.

Here, as described above, in the intention database, in addition to the detailed item and the time zone in which the detailed item is likely to be requested, the numerical value of the mental state of the subject and the value of the change gradient are stored. , Are set in association with these.
For this reason, the information generation unit 458 further extracts a detailed item having a high matching degree with the mental state of the subject SB, that is, the numerical value of the mental state and the value of the change gradient, from the acquired detailed items. .
In addition to the acquired detailed item, the information generation unit 458 is a graphic indicating the numerical value of the mental state and the change gradient associated with the detailed item (that is, a graphic indicating the degree of urgency. Request information including This request information is included in the request presentation screen S2 (see FIG. 10) generated by the screen generation unit 459.

[Configuration of screen generator]
The screen generation unit 459 generates a runtime screen of the request presentation application, and causes the display unit 421 to display the runtime screen via the display control unit of the notification control unit 452. For example, the screen generation unit 459 generates a status presentation screen S1 (see FIG. 9) and a request presentation screen S2 (see FIG. 10) as the runtime screen.

[Configuration of status display screen]
FIG. 9 is a diagram illustrating an example of the state presentation screen S1.
The state presentation screen S1 is a screen showing the numerical value of the current mental state of the subject SB and the transition of the numerical value within a predetermined period.

A graph G indicating the transition of numerical values indicating the mental state of the person SB is arranged in the lower stage. In this graph G, the horizontal axis shows the passage of time, and the vertical axis shows the numerical value of the mental state. The display information included in the state presentation screen S1 is generated by the information generation unit 458.
By confirming such a state presentation screen S1, it is possible to grasp the transition of the mental state of the subject SB.

[Configuration of the request presentation screen]
FIG. 10 is a diagram illustrating an example of the request presentation screen S2. Note that the request presentation screen S2 illustrated in FIG. 10 is a screen including the request items of the subject person SB at 8:00 am, and is a screen in a state where the request items of the subject person SB are confirmed by the operator.
The request presentation screen S2 is a screen that includes the presentation information generated by the information generation unit 458 when it is determined by the state change determination unit 456 and the change gradient determination unit 457 that the respective determination conditions are met. It is a screen on which a request item of the user SB is displayed. The request presentation screen S2 includes the request information extracted based on the presentation information, that is, the numerical value of the mental state of the subject SB, the change gradient of the numerical value, and the time when the mental state changes.

In the request presentation area S21, the content of the extracted detailed item, the numerical value of the mental state stored in association with the detailed item, and an arrow (graphic) indicating the change gradient stored in association with the detailed item, , Is set. Among these, the arrow is an arrow having an inclination corresponding to the absolute value of the change gradient, and by grasping the inclination angle of the arrow with respect to the horizontal direction, the urgency of the content of the corresponding detailed item is grasped. it can.
When a plurality of detailed items are set in such a request presentation area S21, they are preferentially arranged in the matching order with the state of the target person SB. Specifically, for the plurality of detailed items, the numerical value of the mental state of the subject SB, the change gradient of the numerical value, and the detection result used when the numerical value of the mental state is calculated are acquired. In the request presentation area S21, the detection time can be preferentially grasped in descending order of the degree of matching with the numerical value of the mental state associated with each detailed item registered in the intention database, the change gradient, and the time zone. It is set in order from the top.
In addition, as long as a detailed item with a high matching degree can be distinguished from other detailed items, another display form may be sufficient, for example, a detailed item with a high matching degree may blink.

  When the OK button S22 included in the request presentation screen S2 is pressed (input), the state presentation screen S1 is transitioned to. At this time, as shown by the thick line square in FIG. 10, among the detailed items set in the request presenting area S21, the detailed item that matches the actual desired items of the target person SB has been selected by the operator. In this case, the selected detailed item is acquired by the information acquisition unit 454. The update unit 460 updates the mental state values, change gradients, and time zones that are registered in the intention database and that correspond to the detailed items. At this time, the numerical value, the change gradient, and the time zone of the mental state related to the detail item that has been extracted but not selected may be updated.

[Configuration of update unit]
Returning to FIG. 5, the update unit 460 updates the extraction condition from the intention database of the detailed items selected by the operator on the request presentation screen S <b> 2 and acquired by the information acquisition unit 454. Specifically, the update unit 460 updates the mental state value, change gradient, and time zone registered in the intention database in relation to the detailed item. At this time, when the same detail item is selected a plurality of times, the update unit 460 calculates the mental state value, the change gradient, and the time zone based on each detection result when the detail item is extracted. You may comprise so that it may update.
Thereby, it becomes easy to extract and present desired items according to the position of the target person SB.

[Request presentation process]
FIG. 11 is a flowchart showing a request presentation process executed by the information processing apparatus 4 (control unit 45).
The control unit 45 of the information processing apparatus 4 reads and executes the request presentation application from the storage unit 44 in response to an input operation by the operator, thereby executing the following request presentation processing.
In this request presentation process, as shown in FIG. 11, first, the information acquisition unit 454 receives and acquires the detection result transmitted from the detection devices 2 and 3 (step ST1). Since biometric information and detection time are acquired in step ST1, the step ST1 corresponds to the biometric information acquisition step and detection time acquisition step of the present invention.
Next, the state estimation unit 455 estimates the mental state of the subject SB based on the acquired detection result, and calculates a numerical value indicating the mental state (step ST2).
Then, the information generation unit 458 generates display information based on the numerical value, and the screen generation unit 459 generates the state presentation screen S1 based on the display information. Thereby, the screen S1 is displayed on the display unit 421 (step ST3).

Thereafter, state change determination section 456 determines whether or not a period corresponding to the time interval has passed and the determination timing has come (step ST4). If it is determined in this determination process that the determination timing is not reached (step ST4: NO), the AP execution unit 45B returns the process to step ST1.
On the other hand, if it is determined that the determination timing has come (step ST4: YES), determination processing by the state change determination unit 456 and the change gradient determination unit 457 is executed (step ST5).

  If it is not determined in step ST5 that the desire of the subject person SB that he / she wants to cope with some desired item for an unpleasant state is increased (step ST5: NO), the desire is not increased. Therefore, it is determined that the request has not occurred. In this case, the AP execution unit 45B returns the process to step ST1. In addition, as a case where it is not determined that the desire is increasing, as described above, when the numerical value indicating the mental state of the subject SB is greater than 3, the change gradient of the mental state is a positive value. And a case where the change gradient exceeds a predetermined value.

On the other hand, when it is determined in the determination process of step ST5 that the desire of the target person SB that he wants to respond to some request for an unpleasant state is increased (step ST5: YES), the request Is determined to have occurred. In this case, the information generation unit 458 acquires the content of the detailed item, which is a request item according to the target person SB, from the intention database, and generates the presentation information (step ST6).
Then, the screen generation unit 459 generates a request presentation screen S2 based on the presentation information, and displays the screen S1 on the display unit 421 (step ST7).

After this step ST7, when the AP execution unit 45B presses the OK button S22 on the request presentation screen S2, one of the detailed items set in the request presentation area S21, that is, the actual request of the subject SB. It is determined whether or not an item has been selected (step ST8).
If it is determined in the determination process of step ST8 that no detailed item is selected (step ST8: NO), the AP execution unit 45B returns the process to step ST1. Before the process returns to step ST1, an input screen for inputting the opinion and judgment of the operator (in this case, for example, a caregiver) may be displayed, and detailed items other than the displayed detailed items are included. The request presentation screen S2 may be displayed. Then, the update unit 460 updates the contents of the intention database based on the operator's view and judgment input on the input screen and the detailed items selected on the newly displayed request presentation screen S2. May be.

On the other hand, if it is determined in the determination process of step ST8 that any of the detailed items has been selected (step ST8: YES), the information acquisition unit 454 acquires the selected detailed item. And the update part 460 detects the numerical value of the mental state registered in the intention database according to the said detailed item, a change gradient, and the detection result (step ST1) memorize | stored in the memory | storage part 44. (Including the detection result obtained in step ST9) (step ST9).
Thereafter, the AP execution unit 45B returns the process to step ST1.
Thus, the request presentation process is repeatedly executed while the request presentation application is being executed.

[Effect of the first embodiment]
The request presentation system 1 according to the present embodiment described above has the following effects.
A request item extracted by the information generation unit 458 based on the biological information and the detection time of the subject person SB is presented as a request matter according to the intention of the subject person SB by the notification unit 42 as the information presentation unit. . Thereby, the request matter of the target person SB can be transmitted to the person who performs the care and watching of the target person SB. Therefore, it is possible to transmit a request item according to the intention of the subject person SB who cannot communicate the intention by words to another person such as a caregiver.

  Based on the mental state of the target person SB estimated by the state estimation unit 455 and the detection time, the information generation unit 458 generates request information indicating the desired items of the target person SB. According to this, the precision of the request matter according to the mental state of subject SB can be raised.

  When the above-described determination process is performed by the state change determination unit 456 and the change gradient determination unit 457, when the target person SB is in an uncomfortable state and wants a prompt treatment (implementation of requested items), The request matter of the subject SB can be reliably presented to others. Therefore, the convenience of the request presentation system 1 (information processing apparatus 4) can be improved.

  A plurality of candidates for desired items are set in the intention database stored in the storage unit 44, and the information generation unit 458 refers to the intention database, the numerical value of the mental state of the subject SB, the biological information and Request information including candidates according to the detection time of the body motion information is generated. According to this, the request matter of the subject SB can be extracted and presented relatively easily. Moreover, since such a requirement can be set according to the subject SB, the requirement suitable for the mental state of the subject SB can be reliably presented.

  The information generation unit 458 refers to the intention database in the storage unit 44 and extracts candidates corresponding to the mental state of the target person SB from the candidates associated with the time zone including the detection time. Generate request information. According to this, among the demand items that can be classified to some extent according to the time zone, it is possible to reliably present the demand item candidates along the mental state of the current subject SB.

  The information generation unit 458 extracts candidates based on the time zone from the intention database, and further prioritizes candidates that have a high degree of fitness with the numerical value indicating the mental state of the subject SB and the change gradient of the numerical value. Presentation information to be presented. According to this, in addition to being able to easily obtain and present the desired items suitable for the current state of the subject SB, the operator can quickly grasp the desired items most suitable for the state of the subject SB.

  The state change determination unit 456 determines the numerical value of the mental state at the time interval. According to this, it can suppress that the determination process of the said state change determination part 456 generate | occur | produces frequently, and electric power consumption becomes large. Therefore, the information processing device 4 as the request presentation device can be configured by a portable terminal device.

  When the state estimation unit 455 digitizes the mental state of the subject SB, the change of the mental state can be easily grasped, and the transition of the mental state can be easily grasped. Therefore, it is possible to easily present the request information according to a change in the mental state of the subject person SB.

  Since the biological information detection device 2 detects a pulse (pulse wave signal) related to the autonomic nerve as biological information of the subject SB, the subject information is compared with the case where only biological information such as body temperature and blood pressure is detected. The mental state of SB can be estimated more accurately. Accordingly, it is possible to more accurately present the desired items according to the intention of the subject person SB.
