1. A computer configured as an activity amount calculation device for calculating activity amounts of a resident of a dwelling equipped with a plurality of rooms, the activity amount calculation device comprising:
- a calculation unit configured to calculate activity amounts of the resident based on detection signals output from a plurality of detection devices that detect the resident when the resident passes through doorways of the plurality of rooms; and
a summation unit configured to repeatedly calculate a total activity amount of the resident in a predetermined period by summing the activity amounts calculated by the calculation unit, whereinupon detection of the resident by different detection devices included among the plurality of detection devices, the calculation unit calculates an activity amount of the resident based on a preset relationship between the different detection devices and a reference activity amount, whereinthe calculation unit uses the reference activity amount as the activity amount of the resident when an elapsed period between detection by one of the different detection devices that has detected first and detection by another of the different detection devices that has detected second is longer than or equal to a preset reference period, andthe calculation unit uses a product of the reference activity amount and a coefficient larger than one as the activity amount of the resident when the elapsed period is shorter than the reference period.

Abstract
An activity amount calculation system includes a plurality of detection units and an activity amount calculation device. The plurality of detection units detect a resident and output detection signals when the resident passes through doorways of a plurality of rooms. The calculation device includes a calculation unit and a summation unit. Upon detection of the resident by the detection units, the calculation unit calculates an activity amount of the resident based on relationships between detection units and reference activity amounts. The summation unit repeatedly calculates a total activity amount of the resident in a predetermined period by summing activity amounts calculated by the calculation unit.

6. An activity amount calculation method of calculating activity amounts of a resident of a dwelling equipped with a plurality of rooms using an activity amount calculation device, the activity amount calculation method performed by a computer and comprising:
-
(a) a step of calculating activity amounts of the resident based on detection signals output from a plurality of detection devices that detect the resident when the resident passes through doorways of the plurality of rooms; and (b) a step of repeatedly calculating a total activity amount of the resident in a predetermined period by summing the activity amounts calculated in step (a), wherein in step (a), upon detection of the resident by different detection devices included among the plurality of detection devices, an activity amount of the resident is calculated based on a preset relationship between the different detection devices and a reference activity amount, wherein the calculation unit uses the reference activity amount as the activity amount of the resident when an elapsed period between detection by one of the different detection devices that has detected first and detection by another of the different detection devices that has detected second is longer than or equal to a preset reference period, and the calculation unit uses a product of the reference activity amount and a coefficient larger than one as the activity amount of the resident when the elapsed period is shorter than the reference period. - View Dependent Claims (7, 8, 9, 10)

11. A non-transitory computer-readable recording medium having recorded therein a program for calculating activity amounts of a resident of a dwelling equipped with a plurality of rooms using a computer, the program including an instruction for causing a processor of the computer to execute:
-
(a) a step of calculating activity amounts of the resident based on detection signals output from a plurality of detection devices that detect the resident when the resident passes through doorways of the plurality of rooms; and (b) a step of repeatedly calculating a total activity amount of the resident in a predetermined period by summing the activity amounts calculated in step (a), wherein in step (a), upon detection of the resident by different detection devices included among the plurality of detection devices, an activity amount of the resident is calculated based on a preset relationship between the different detection devices and a reference activity amount, wherein the calculation unit uses the reference activity amount as the activity amount of the resident when an elapsed period between detection by one of the different detection devices that has detected first and detection by another of the different detection devices that has detected second is longer than or equal to a preset reference period, and the calculation unit uses a product of the reference activity amount and a coefficient larger than one as the activity amount of the resident when the elapsed period is shorter than the reference period. - View Dependent Claims (12, 13, 14, 15)
