Abstract

A content presentation system, a content presentation device, and a content presentation method that reduce a burden on a user and present suitable contents to the user with high accuracy are provided. The present technology provides a content presentation system including a computer device that holds content information associated with emotion information indicating an emotion of a user, in which the computer device at least includes a machine learning model that, on the basis of a plurality of pieces of content information presented to the user corresponding to desired emotion information indicating emotion information desired by the user and content information selected by the user from the plurality of pieces of content information, performs machine learning so as to present the content information suitable for the emotion information.

First claim

The invention claimed is:

1. A content presentation system comprising:
a computer device that holds content information associated with emotion information indicating an emotion of a user; and
an operation interface unit,
wherein the operation interface unit encourages continuous or stepwise input of desired emotion information, and wherein the computer device at least includes a machine learning model that, on a basis of a plurality of pieces of content information presented to the user corresponding to the desired emotion information that is predetermined in a route formed by the continuous or stepwise input and content information selected by the user from the plurality of pieces of content information presented to the user, performs machine learning to present content information suitable for the desired emotion information.

2. The content presentation system according to claim 1 ,
wherein the emotion information and the content information are associated with each other on a basis of a coordinate system having elements of the emotion as coordinate axes.

3. The content presentation system according to claim 2 ,
wherein the coordinate system is a Russell's circumplex model.

4. The content presentation system according to claim 1 ,
wherein current emotion information indicating the user's current emotion is estimated on a basis of biometric information obtained from sensing information detected by a biometric sensor.

5. The content presentation system according to claim 4 ,
wherein the current emotion information is corrected on a basis of context information related to a context of the user obtained from sensing information detected by a context sensor.

6. The content presentation system according to claim 4 further comprising an emotion estimation unit,
wherein the emotion estimation unit performs machine learning as to estimate the current emotion information.

7. The content presentation system according to claim 1 ,
wherein the operation interface unit presents the content information corresponding to the desired emotion information and/or encourages selection of the content information.

8. A content presentation device that holds content information associated with emotion information indicating an emotion of a user, the content presentation device at least comprising:
an operation interface unit, wherein the operation interface unit encourages continuous or stepwise input of desired emotion information; and
a machine learning model that, on a basis of a plurality of pieces of content information presented to the user corresponding to a shape of a route formed by the continuous or stepwise input, the desired emotion information, and content information selected by the user from the plurality of pieces of content information presented to the user, performs machine learning to present content information suitable for the desired emotion information.

9. A content presentation method comprising a computer device that holds content information associated with emotion information indicating an emotion of a user, the content presentation method at least comprising:
receiving continuous or stepwise input of desired emotion information; and
on a basis of a plurality of pieces of content information presented to the user corresponding to a shape of a route formed by the continuous or stepwise input, the desired emotion information, and content information selected by the user from the plurality of pieces of content information presented to the user, performing machine learning to present content information suitable for the desired emotion information by the computer device.
