Questioning unit 26 presents three types of cognitive function tests to the user of wristwatch 1 on display unit 21 of master device 2: time orientation test, figure recognition test (cue reproduction test), and clock drawing test. do. The questioning section 26 may present these tests by the administrator operating the master device 2, but the administrator can automatically present these tests by pressing the buttons on the operation section 12 of the wristwatch 1 without operating the master device 2. It is preferable that the wristwatch 1 and the base unit 2 are linked so that they are activated automatically. This simplifies the operation for activating the application for performing the cognitive function test on master device 2 .

FIG. 3 is a diagram showing an example of a time orientation test displayed on base unit 2. As shown in FIG. The time orientation test is for determining whether or not the user (subject) of the wristwatch 1 can recognize the current time and numbers. The screen 40 is displayed on the display unit 21 . On the screen 40, the year, month, day, hour, and minute response columns 41 are displayed below the sentences indicating instructions to the subject, and further below these are the numbers 0 to 9 and a selection button 42 for deletion (correction) and a selection button 42 for selection. An input button 43 is displayed for inputting the given number as an answer. The test subject operates these buttons on the display unit 21 under the direction of the administrator to input the answer in numbers.

FIG. 4 is a diagram showing an example of a graphic recognition test displayed on master device 2. In FIG. The figure recognition test is to determine whether or not the subject can recognize and memorize the figure. and the figure to answer. The questioning unit 26 causes the display unit 21 to sequentially display, for example, screens 51a to 51f shown in FIG. 4 at regular time intervals as a pattern recognition test. For example, the first screen 51a displays a meal mark 52a and an explanation of its meaning, and the following several to ten screens 51b to 51e each display marks 52b to 52e different from the first mark 52a. be done. On the final screen 51f, a sentence asking about the mark displayed on the first screen 51a is simultaneously displayed along with a plurality of marks 52a to 52e that have been displayed so far, including the correct answers. The subject selects one mark on the screen 51f under the direction of the administrator.

FIGS. 5A and 5B are diagrams showing an example of a clock drawing test displayed on master device 2. FIG. The clock drawing test is for determining whether or not the subject can read two-hand and three-hand clocks, and consists of a two-hand drawing test and a three-hand drawing test. The questioning unit 26 causes the display unit 21 to display, for example, a screen 61 shown in FIG. 5A as the two-needle drawing test and a screen 62 shown in FIG. 5B as the three-needle drawing test. The dial 63, hour hand 64 and minute hand 65 on the screen 61 for the two-needle drawing test, and the dial 63, hour hand 64, minute hand 65 and second hand 66 on the screen 62 for the three-needle drawing test, along with sentences indicating instructions to the subject. Is displayed. Subjects, under the direction of the administrator, trace the hands of the displayed clock in a clockwise or counterclockwise direction to rotate each of the hands to match the designated time.

The determination unit 27 determines the degree of cognitive function of the subject by determining whether the user (subject) of the wristwatch 1 has passed the cognitive function test. If the year, month, day, hour, and minute answered by the subject in the time orientation test match the current time indicated by the clock built in master device 2 or the timekeeping unit 16 of wristwatch 1, determination unit 27 determines time orientation. It is determined that the orientation test is passed and the subject can recognize the current time and numbers, and if they do not match, the time orientation test is determined to have failed and the subject cannot recognize the current time and numbers. If the mark selected by the subject in the figure recognition test matches the mark 52a displayed on the first screen 51a, the determination unit 27 determines that the figure recognition test has passed and the subject can recognize and memorize the figure. If they do not match, the figure recognition test has failed and the subject is judged to be incapable of recognizing and remembering the figure.

If the time indicated by the hands set by the subject in the two-hand drawing test matches the specified time, the determination unit 27 determines that the two-hand drawing test is passed and the subject can read the two-hand clock. In this case, the determination unit 27 further determines that if the time indicated by the hands set by the subject in the three-hand drawing test matches the specified time, the three-hand drawing test is also passed and the subject can read the three-hand clock. If not, the 3-hand drawing test has failed and the subject is determined to be able to read a 2-hand clock but not a 3-hand clock. If the time indicated by the hands set by the subject in the two-hand drawing test does not match the specified time, the determination unit 27 fails the two-hand drawing test and the three-hand drawing test, and the subject does not pass the two-hand clock. It is determined that even a three-hand clock cannot be read. The determining unit 27 determines that the clock drawing test is passed if the two-hand drawing test is passed, and that the clock drawing test is failed if the two-hand drawing test is not passed.

In general, a person who cannot read a two-hand clock cannot read a three-hand clock. Therefore, if the two-hand drawing test fails, there is no need to conduct the three-hand drawing test. need not be presented. In order to improve the judgment accuracy, especially in the figure recognition test and the clock drawing test, the question setting unit 26 sets the same questions a plurality of times, and the judgment unit 27 determines whether or not the correct answer rate exceeds the reference value. You may judge pass/fail.

Table 1 shows the correspondence between the results of the cognitive function test and the display modes of wristwatch 1 selected by master device 2 .

"O" in the table indicates pass, and "X" indicates failure. People who can't read a 2-hand clock can't read a 3-hand clock (people who can read a 3-hand clock can also read a 2-hand clock). If the test passed, it is not described. Since a person who cannot recognize the current time or numbers cannot read a two- or three-hand clock, Table 1 shows that if the time orientation test fails and the two-hand drawing test or three-hand drawing test passes, Not listed.

The selection unit 28 selects the display mode of the display unit 11 of the wristwatch 1 according to the determination result of the determination unit 27 . The selection unit 28 selects the 3-needle display a if the 2-needle drawing test and the 3-needle drawing test are determined to have passed, and if the 2-needle drawing test is determined to have passed and the 3-needle drawing test is determined to have failed. 2 needle display b is selected. If the clock drawing test is unsuccessful and the time orientation test is unsuccessful, the selection unit 28 displays the one-hand display c if the graphic recognition test is unsuccessful. If so, digital display d is selected. If the clock drawing test and the time orientation test are determined to be unsuccessful, the selection unit 28 displays the graphic display e if the graphic recognition test is determined to be unsuccessful, and if the graphic recognition test is also determined to be unsuccessful. Then select color display f. The selection unit 28 transmits data indicating the selected display mode and an instruction to switch the display mode to the wristwatch 1 via the communication unit 23 .

The setting unit 29 allows the administrator to set the figure or color to be displayed when the figure display e or the color display f is performed on the wristwatch 1 and the time zone in which it is displayed on the display unit 21. It accepts the setting data and transmits the setting data to the wristwatch 1 via the communication unit 23 .

In this way, master device 2 issues cognitive function test questions, judges the results, and selects the display format of wristwatch 1, and wristwatch 1 receives an instruction to switch the display format and data indicating which display format was selected. The processing is simplified by performing the switching by using the According to the wristwatch 1 and the master device 2, even if the symptoms of dementia progress, it is possible to grasp the degree of the user's cognitive function at that point in time and realize display in an appropriate display form.

Different from the above example, master device 2 may also hold display data for each display mode and transmit display data for the selected display mode to wristwatch 1 together with a display mode switching instruction. Even if the storage capacity of the storage section 14 of the wristwatch 1 is limited, the storage capacity of the storage section 24 of the master device 2 is generally large. It is possible to increase the number of displays more than the street, and it is possible to make detailed display settings according to the symptoms of dementia of the user. Further, although it is preferable that master device 2 has the functions of questioning unit 26 and determination unit 27 , wristwatch 1 may have the functions of selection unit 28 and setting unit 29 . In other words, the master device 2 may set questions and determine the results of the cognitive function test, while the wristwatch 1 may select the display mode, set the contents of the graphic display e and the color display f, and set the switching time.

The wristwatch 1 is not limited to a digital quartz watch, but may be an analog quartz watch or an analog-digital mixed watch having both hands and an LCD as mechanical parts. However, in the case of a watch with pointers, the display of the pointers cannot be turned off, and digital display d, graphic display e, and color display f are not possible. Therefore, only those who can pass both the time orientation test and the graphic recognition test are included. In the case of a watch with hands, it is necessary to drive the hands independently without interlocking with each other. When the two-hand display is b, the minute hand and second advance are superimposed and driven, and when the one-hand display is c, the hour hand, minute hand and the second hand are driven. All you have to do is drive by overlapping the seconds.

In the graphic display e and color display f, not only the graphic or color but also the time may be displayed in a small size so as not to be conspicuous. People who cannot recognize the current time and numbers cannot recognize the time, but by displaying the time, the administrator (caregiver) can check whether the figure or color is displayed correctly in the correct time zone.

The program that implements the functions of the parent device 2 may be provided by means of communication, or may be provided by being stored in a recording medium such as a CD-ROM.
