Abstract

A notification management device includes: an operation log obtainer that obtains an operation log indicating a state of an information source appliance operated by a user, from the information source appliance; an operation log storage that stores the operation log obtained by the operation log obtainer; a setting content information storage that stores setting content information indicating setting content of a voice notification of an utterance appliance set by the user; a voice notification log storage that stores a voice notification log indicating a history of the voice notification output by the utterance appliance based on the setting content; an estimator that estimates the user's interest based on at least one of the operation log, the setting content information, or the voice notification log; and a push notification transmitter that transmits, to a terminal device, a push notification for notifying the user of notification content related to the estimated interest.

First claim

The invention claimed is:

1. A notification management device that communicates, via a network, with each of a terminal device, a first appliance, and a second appliance that outputs a voice notification to a user, the notification management device comprising:
a first obtainer that obtains appliance state information indicating a state of the first appliance operated by the user, from the first appliance;
a first storage that stores the appliance state information obtained by the first obtainer;
a second storage that stores setting content information indicating setting content of the voice notification of the second appliance set by the user;
a third storage that stores voice notification history information indicating a history of the voice notification output by the second appliance based on the setting content;
an estimator that estimates an interest of the user based on at least one of the appliance state information, the setting content information, or the voice notification history information; and
a notifier that transmits, to the terminal device, a push notification for notifying the user of notification content related to the interest of the user estimated by the estimator.

2. The notification management device according to claim 1 , further comprising:
a fourth storage that stores push notification history information indicating a history of the push notification transmitted by the notifier;
a fifth storage that stores already-read information indicating that the notification content of the push notification is marked as read by the user; and
a transmitter that transmits the push notification history information and the already-read information to at least one of the second appliance or the terminal device.

3. The notification management device according to claim 1 , further comprising:
a fifth storage that stores already-read information indicating that the notification content of the push notification is marked as read by the user,
wherein the estimator estimates the interest of the user based on the appliance state information, the setting content information, the voice notification history information, and the already-read information.

4. The notification management device according to claim 1 , further comprising:
a second obtainer that obtains questionnaire information indicating a result of a questionnaire regarding the interest of the user answered by the user,
wherein the estimator estimates the interest of the user based on the appliance state information, the setting content information, the voice notification history information, and the questionnaire information.

5. The notification management device according to claim 1 ,
wherein the estimator estimates the interest of the user by referring to correspondence information indicating a correspondence relationship between the appliance state information, the setting content information, the voice notification history information, and the interest of the user, based on the appliance state information, the setting content information, and the voice notification history information.

6. A notification system comprising:
a terminal device;
a first appliance;
a second appliance; and
a notification management device that communicates with each of the terminal device, the first appliance, and the second appliance via a network,
wherein the first appliance includes a first communicator that transmits appliance state information indicating a state of the first appliance operated by a user, to the notification management device,
the second appliance includes an outputter that outputs a voice notification to the user,
the notification management device includes:
an obtainer that obtains the appliance state information from the first appliance;
a first storage that stores the appliance state information obtained by the obtainer;
a second storage that stores setting content information indicating setting content of the voice notification of the second appliance set by the user;
a third storage that stores voice notification history information indicating a history of the voice notification output by the second appliance based on the setting content;
an estimator that estimates an interest of the user based on at least one of the appliance state information, the setting content information, or the voice notification history information; and
a notifier that transmits, to the terminal device, a push notification for notifying the user of notification content related to the interest of the user estimated by the estimator, and
the terminal device includes:
a second communicator that receives the push notification from the notification management device; and
a display that displays the push notification received by the second communicator.

7. A control method of a notification management device that communicates, via a network, with each of a terminal device, a first appliance, and a second appliance that outputs a voice notification to a user, the control method comprising:
(a) obtaining appliance state information indicating a state of the first appliance operated by the user, from the first appliance;
(b) storing the appliance state information obtained in (a), in a first storage;
(c) storing setting content information indicating setting content of the voice notification of the second appliance set by the user, in a second storage;
(d) storing voice notification history information indicating a history of the voice notification output by the second appliance based on the setting content, in a third storage;
(e) estimating an interest of the user based on at least one of the appliance state information, the setting content information, or the voice notification history information; and
(f) transmitting, to the terminal device, a push notification for notifying the user of notification content related to the interest of the user estimated in (e).

8. A non-transitory computer-readable recording medium having recorded thereon a program for causing a computer to execute the control method of a notification management device according to claim 7 .

9. A notification management device that communicates, via a network, with each of a terminal device, a first appliance, and a second appliance that outputs a voice notification to a user, the notification management device comprising:
a first obtainer that obtains appliance state information indicating a state of the first appliance operated by the user, from the first appliance;
a first storage that stores the appliance state information obtained by the first obtainer;
a second storage that stores setting content information indicating setting content of the voice notification of the second appliance;
a third storage that stores voice notification history information indicating a history of the voice notification output by the second appliance based on the setting content;
an estimator that estimates an interest of the user based on at least one of the appliance state information, the setting content information, or the voice notification history information;
a selector that determines whether to notify the user of notification content related to the interest of the user estimated by the estimator, and selects a notification method; and
a notifier that transmits a notification indicating the notification content to at least one of the terminal device or the second appliance by the notification method selected by the selector, when the selector determines to notify the user of the notification content.

10. The notification management device according to claim 9 ,
wherein the selector selects, as the notification method, at least one of a push notification transmitt
