  When the determination unit 26 determines the cognitive function level for each item for a certain target person, the item determination unit 27 determines one or more items to be presented to the presentation unit 11 based on the determination result. When one or more items to be presented to the presentation unit 11 are determined by the item determination unit 27, the determination unit 26 determines a cognitive function level from the communication unit 23 by using a notification signal indicating the determined one or more items. To the first device 1 associated with the person.

  Next, operation | movement of the cognitive function assistance system 10 of this embodiment is demonstrated.

  The subject who is the support target of the cognitive function exclusively uses the first device 1 associated with the subject. On the presentation unit 11 of the first device 1, buttons corresponding to all items are displayed in the initial state. When the cognitive function of a certain item is reduced, the subject operates a button corresponding to the item with the reduced cognitive function among the plurality of buttons displayed on the presentation unit 11 of the first device 1. It is thought that the presentation information about is obtained. For example, a subject who has difficulty in understanding the time (season) due to disorientation frequently selects the button “Now when”, so the number of times the button “Now” is selected Expected to be more than the number of times.

  When the subject operates the selection unit 12 of the first device 1 to select a desired button (item), the communication unit 13 selects the selection information of the button (item) selected using the selection unit 12 and the first device. The transmission signal including the identification information of 1 is transmitted to the second device 2. When the communication unit 23 of the second device 2 receives the transmission signal transmitted from the first device 1 via a wireless router or the like, the control unit 25 receives the transmission signal received by the communication unit 23. Based on the selection information and the identification information included in the transmission signal, the control unit 25 counts up the number of selections of the button selected by the selection unit 12 for the first device 1 operated by the target person, and calculates this selection number. The data is stored in the storage unit 24. Here, the control unit 25 may store the selection information itself received from the first device 1 via the wireless router in the storage unit 24. In the storage unit 24, correspondence information between the identification information of a plurality of subjects and the identification information of the first device 1 associated with each subject is registered. Therefore, the control unit 25 can count the number of times each item is selected for each target person based on the identification information included in the transmission information and the correspondence information stored in the storage unit 24. The number of times each item is selected for each subject is stored in the storage unit 24. Note that a plurality of first devices 1 correspond to one target person as in the case where one target person uses a terminal device 1A such as a smartphone and a terminal device 1B such as a television receiver. It may be attached. In such a case, the control unit 25 determines the number of times of selection in the plurality of first devices 1 based on the selection information in the plurality of first devices 1 associated with one target person. The number of times of selection of each item may be obtained by summing up.

  When the first device 1 associated with a certain target person is used for a certain period (for example, a period of several days to one month), the determination unit 26 of the second apparatus 2 selects each item for the target person. The number of times is read from the storage unit 24, and the cognitive function level of the subject is determined for each item. The determination unit 26 compares the number of selections with a predetermined determination criterion for each item, and determines that the cognitive function level is low if the number of selections is greater than the determination criterion. Note that the determination unit 26 may determine the cognitive function level in a plurality of stages by comparing the determination criteria of the plurality of stages with the number of selections.

  When the determination unit 26 determines the cognitive function level for each of the plurality of items for each target person, the item determination unit 27 determines one or more items (the items to be presented by the presentation unit 11 according to the determination result of the determination unit 26). In this embodiment, three items) are determined. That is, the item determination unit 27 determines three items as items to be presented to the presentation unit 11 in order from the items with the lowest cognitive function level (poor cognitive function) among the plurality of items. Therefore, the item determination unit 27 determines three items as items to be presented to the presentation unit 11 in order from the item with the largest selection number among the plurality of items.

  When the item determining unit 27 determines one or more items to be presented to the presenting unit 11 for a certain target person, the control unit 25 determines the identification information of the first device 1 associated with the target person as the destination address. Create a notification signal that includes the item in the transmission data. Then, the control unit 25 causes the communication unit 23 to transmit the created notification signal.

  When the communication unit 13 of the first device 1 receives the notification signal transmitted from the second device 2 via a wireless router or the like, the control unit 15 converts the notification signal into the notification signal based on the notification signal received by the communication unit 13. A screen for displaying the included items is created, and the created screen is displayed on the presentation unit 11.

  For example, when the determination unit 26 determines that the location / date-time orientation and human recognition of a certain target person are insufficient, and determines that the cognitive function level of these items is low, the item determination unit 27 selects these items. To be presented on the presentation unit 11. As a result, as shown in FIG. 3A, the presentation unit 11 of the first device 1 includes a button B1 “where is here”, a button B2 “when now”, and a button B3 “this person”. Always display.

In the care facility 100, a timetable (schedule) of matters (meals, bathing, walks, recreation, etc.) that the subject performs in one day is planned in advance. "To do next" means the next thing planned for the timetable.

  In addition, when the determination unit 26 determines that the time recognition and the past memory are insufficient, the display unit 11 of the first device 1 includes a button (specific item) for displaying specific presentation information. May always be displayed. In this case, a screen as shown in FIG. 3C is displayed on the presentation unit 11 of the first device 1. Three buttons B14, B12, and B13 are displayed on the screen of the presentation unit 11. The upper button B14 is a button (specific item) for displaying specific presentation information, and an explanatory note “important” is displayed. The specific presentation information corresponding to the specific item is, for example, information important for the target person, and is information that the target person particularly wants to remember. As specific presentation information, for example, information on a scheduled visit that the subject's grandchild will visit next, and information on a close relative of the subject (for example, the spouse, parent, child, grandchild, etc. of the subject) Etc.). The caregiver may register in advance the specific presentation information obtained by hearing from the target person in the second device 2.

  The subject looks at the screen of the presentation unit 11 and touches a button (item) corresponding to the desired presentation information in order to confirm the presentation information of any item. When the subject touches the button displayed on the presentation unit 11, an operation signal indicating the button operated by the control unit 15 is output from the selection unit 12, and the control unit 15 is operated based on the operation signal. Presentation information corresponding to the button is read from the storage unit 14 and displayed on the presentation unit 11. The control unit 15 causes the communication unit 13 to transmit a request signal requesting the second device 2 for presentation information corresponding to the operated button, and displays the presentation information returned from the second device 2 on the presentation unit 11.
