Abstract

A system includes a sensor detecting entry/exit of a person to/from a toilet and a sensor detecting leaving/sitting on a toilet seat installed on a toilet bowl; acquires excretion information indicating at least a start and an end of excretion, based on imaging data captured by an image capture apparatus installed in such a way as to include, in an image capture range, an excretion range of excrement in the bowl; authenticates a person performed entry/exit, and determines whether the person is a person to be assisted as a user of the toilet or a helper; outputs notification information to a notification destination, based on a detection event indicated by the excretion information, entry/exit information, leaving/sitting information, and an authentication result, and a notification condition; and stores, as the notification condition, necessity of notification, and the notification information and the notification destination when notification is necessary, for each events.

First claim

What is claimed is:

1. An information processing system comprising:
at least one memory storing instructions and a notification condition;
at least one processor configured to execute the instructions to do information processing, the information processing includes acquiring excretion information indicating at least a start and an end of excretion, based on imaging data captured by an image capture apparatus installed in such a way as to include, in an image capture range, an excretion range of excrement in a toilet bowl of a toilet;
a first sensor configured to detect entry/exit of a person to/from the toilet; and
a second sensor configured to detect leaving and sitting on a toilet seat installed on the toilet bowl, wherein
the information processing further includes
authenticating a person who has performed entry/exit to/from the toilet, and also determining whether the person is a person to be assisted as a user of the toilet or a helper who assists the user,
outputting notification information to a notification destination, based on a detection event indicated by the excretion information acquired by the acquiring, entry/exit information detected by the first sensor, leaving/sitting information detected by the second sensor, and an authentication result in the authenticating, and the notification condition, and,

the at least one memory stores, as the notification condition, necessity of notification, and the notification information and the notification destination when notification is necessary, for each of the detection events.

2. The information processing system according to claim 1 , wherein
the notification condition includes importance information indicating importance of notification, and
the outputting is outputting the notification information in a state including the importance information or in a state indicating the importance information.

3. The information processing system according to claim 1 , wherein the at least one memory stores, as the notification condition, necessity of notification, and the notification information and the notification destination when notification is necessary, for each of the detection events and each person to be assisted as the user.

4. The information processing system according to claim 1 , wherein
the detection event includes a first event being an event in which a person to be assisted as the user is sitting on the toilet seat for a certain period of time or more, and,
as the notification condition with respect to the first event, the notification destination includes a contact address of a helper who assists the user, and the notification information includes an alert for requesting assistance.

5. The information processing system according to claim 1 , wherein
the acquiring is acquiring, as at least a part of the excretion information, information indicating whether the imaging data captured by the image capture apparatus includes a foreign body being an object other than feces and urine as a subject excluding the toilet bowl and washing liquid for the toilet bowl,
the detection event includes a second event being an event in which the foreign body is detected, and,
as the notification condition with respect to the second event, the notification destination includes a contact address of a helper who assists a person to be assisted as the user, and the notification information includes an alert for requesting removal of the foreign body.

6. The information processing system according to claim 1 , wherein
the detection event includes a third event being an event in which dirt is detected in at least one of the image capture apparatus, the first sensor, and the second sensor, and,
as the notification condition with respect to the third event, the notification destination includes a contact address of a person who can become the helper, and the notification information includes an alert for requesting removal of the dirt.

7. The information processing system according to claim 1 , wherein
the detection event includes a fourth event being an event in which it is detected that the helper enters the toilet while a person to be assisted as the user enters the toilet,
as the notification condition with respect to the fourth event, the notification destination includes a contact address of a person who can become the helper other than the helper related to the fourth event, and the notification information includes information notifying that a person to be assisted as the user is being assisted, and,
when the fourth event occurs, the outputting is not executed notification related to another specific detection event even when the another specific detection event occurs, until at least a state indicated by the fourth event disappears.

8. The information processing system according to claim 1 , wherein
the information processing further includes receiving, from a person who can become the helper, rush information for notifying a person who can become another helper of rushing for assisting the user,
the detection event includes a fifth event indicating that the rush information has been received by the receiving, and,
as the notification condition with respect to the fifth event, the notification destination includes a contact address of a person who can become the another helper, and the notification information includes information for notifying of rushing for assisting a person to be assisted as the user.

9. The information processing system according to claim 1 , wherein the information processing further includes setting the notification condition.

10. The information processing system according to claim 1 , further comprising the image capture apparatus.

11. An information processing method comprising:
acquiring excretion information indicating at least a start and an end of excretion, based on imaging data captured by an image capture apparatus installed in such a way as to include, in an image capture range, an excretion range of excrement in a toilet bowl of a toilet;
detecting, by a first sensor, entry/exit of a person to/from the toilet;
detecting, by a second sensor, leaving and sitting on a toilet seat installed on the toilet bowl;
authenticating a person who has performed entry/exit to/from the toilet, and also determining whether the person is a person to be assisted as a user of the toilet or a helper who assists the user;
storing a notification condition; and
outputting notification information to a notification destination, based on a detection event indicated by the excretion information acquired in the acquiring, entry/exit information detected by the first sensor, leaving/sitting information detected by the second sensor, and an authentication result in the authenticating, and the notification condition,
wherein the storing includes storing, as the notification condition, necessity of notification, and the notification information and the notification destination when notification is necessary, for each of the detection events.

12. A non-transitory computer-readable medium storing a program for causing a computer to execute processing including:
acquiring excretion information indicating at least a start and an end of excretion, based on imaging data captured by an image capture apparatus installed in such a way as to include, in an image capture range, an excretion range of excrement in a toilet bowl of a toilet;
detecting, by a first sensor, entry/exit of a person to/from the toilet;
detecting, by a second sensor, leaving and sitting on a toilet seat installed on the toilet bowl;
authenticating a person who has performed entry/exit to/from the toilet, and also determin
