Generating a representation of a user's reaction to media content
[Object] To provide a client apparatus, control method, system and program capable of presenting emotion expression data showing viewing reactions of other users or a user himself or herself. [Solution] There is provided a client apparatus including: an acquisition unit that acquires a reaction of a viewing user to a content; an emotion estimation unit which estimates an emotion of a viewing user based on reaction information of the viewing user acquired by the acquisition unit; a determination unit that determines emotion expression data representing an emotion estimated by the emotion estimation unit; and an output unit that outputs emotion expression data determined by the determination unit.
1. A client apparatus comprising:
at least one sensor that acquires a reaction of a viewing user to a content; and
a processor that is configured to implement
an emotion estimation function which estimates an emotion of a viewing user based on reaction information of the viewing user acquired by the at least one sensor;
a determination function that determines emotion expression data representing an emotion estimated by the emotion estimation function; and
an output function that outputs the emotion expression data determined by the determination function,
in which the emotion expression data represents estimated emotion and is formed of text data of an onomatopoeic word without including an actual voice or actual words from any viewing user and without including a video of the any viewing user,
wherein the determination function determines the emotion expression data based on an emotion for which emotion estimation results of a plurality of viewing users have been integrated, and
wherein the output function starts an output of first data determined based on an integration of emotion estimation results of specific viewing users, and afterwards starts an output of second emotion expression data determined based on an integration of emotion estimation results of an unspecified large number of viewing users.
2. The client apparatus according to claim 1 , further comprising:
a transmission function that transmits, to a server, information showing an emotion estimated by the emotion estimation function; and
a reception function that receives, from the server, information showing the emotion for which the emotion estimation results of the plurality of viewing users have been integrated.
3. The client apparatus according to claim 1 , wherein the output function completes an output of the first emotion expression data, and afterwards starts an output of the second emotion expression data.
4. The client apparatus according to claim 1 , wherein the determination function determines a type of emotion expression data corresponding to at least one of a viewer demographic of the content or an attribute of the viewing user.
5. The client apparatus according to claim 1 , wherein the at least one sensor collects audio of the viewing user as a reaction of the viewing user.
6. The client apparatus according to claim 1 , wherein the at least one sensor images a face image of the viewing user as a reaction of the viewing user.
7. The client apparatus according to claim 1 , wherein the output function outputs the emotion expression data in coordination with an external apparatus.
