In-home-presence probability calculation method, server apparatus, and in-home-presence probability calculation system
First Claim
1. A device management method used in a server apparatus that manages, via a network, a plurality of devices provided in a home, the method comprising:
- receiving operation information on one of a plurality of devices in the home, via the network, every time a certain operation is performed for the one of the plurality of devices;
for each of the plurality of devices, specifying operation times at which the certain operation has been performed, in accordance with the received operation information;
receiving, every time a state is entered in which it is expected that no one is at home, time information of a time at which the state has been entered;
specifying in-home-absence times at which a state has been entered in which it is expected that no one is at home, in accordance with the received time information;
for each of the plurality of devices, calculating time differences for the specified operation times, each of the time differences being a difference between a corresponding one of the specified operation times and an in-home-absence time that is first specified within a predetermined period from the corresponding one of the specified operation times; and
for each of the plurality of devices, specifying the performed certain operation as a behavior pattern of the person correlated to a behavior when the person continues being at the home when a ratio of a frequency of the calculated time differences regarding the corresponding one of the plurality of devices, each of which is lower than a particular threshold value, is equal to or lower than an other threshold value.

Abstract
A management method manages devices in a home includes, receiving operation information on one of the devices when an operation is performed for the one of the devices, specifying times at which the operation was performed, in accordance with the information, and receiving, whenever a state is entered when no one is expected to be home, time information when the state has been entered. Specifying in-home-absence times at which a state has been entered when no one is expected to be home, according to the time information, for each of the devices, calculating time differences for the specified operation times, and for each of the devices, specifying the performed operation as a first behavior of the person correlated to a behavior before the person leaves home, when variation of the calculated time differences of the corresponding one of the devices is equal to or lower than a threshold.

6. A server apparatus that manages, via a network, a plurality of devices arranged in a home, the server apparatus comprising:
-
one or more memories; and circuitry which, in operation, receives operation information on one of a plurality of devices in the home via the network every time a certain operation is performed for the one of the plurality of devices; for each of the plurality of devices, specifies operation times at which the certain operation has been performed, in accordance with the received operation information; receives, every time a state is entered in which it is expected that no one is at home, time information of a time at which the state has been entered; specifies in-home-absence times at which a state has been entered in which it is expected that no one is at home, in accordance with the received time information; for each of the plurality of devices, calculates time differences for the specified operation times, each of the time differences being a difference between a corresponding one of the specified operation times and an in-home-absence time that is first specified within a predetermined period from the corresponding one of the specified operation times; and for each of the plurality of devices, specifying the performed certain operation as a behavior pattern of the person correlated to a behavior when the person continues being at the home when a ratio of a frequency of the calculated time differences regarding the corresponding one of the plurality of devices, each of which is lower than a particular threshold value, is equal to or lower than an other threshold value. - View Dependent Claims (7, 8, 9, 10)
