Terminal apparatus, function suggestion method, storage medium, and server apparatus

A function suggestion method performed by a terminal apparatus comprising;

• transmitting, from the terminal apparatus to a server apparatus, a suggestion request requesting a suggestion of a function to be invoked in the terminal apparatus:
• receiving, by the terminal apparatus from the server apparatus, a suggestion response that specifies n suggested function determined by the server apparatus in response to the suggestion request;
• and
• invoking, by the terminal apparatus, the suggested function specified by the suggestion response.
• wherein the suggestion request includes face image data of a user of the terminal apparatus, and the suggested function is determined by applying the face image data to a learned model at the server apparatus.
• wherein the function suggestion method further comprises:
• evaluating, based on face images of the user, a degree of change in facial expressions of the user before and after invoking the suggested function;
• and
• transmitting, from the terminal apparatus to the server apparatus, a learning request requesting re-teaming of the learned model when the evaluated degree of change in the facial expressions satisfies a predetermined condition.

A non-transitory computer-readable storage medium having stored therein a computer program which, when executed by a processor of a terminal apparatus, causes the terminal apparatus to:

• transmit, to the server apparatus, a suggestion request requesting a suggestion of a function to be invoked in the terminal apparatus, the suggestion request including face image data of a user of the terminal apparatus;
• receive, from the server apparatus, a suggestion response that specifies a suggested function determined by the server apparatus in response to the suggestion request, the suggested function being determined by applying the face image data to a learned model at the server apparatus;
• invoke the suggested function specified by the suggestion response;
• evaluate, based on face images of the user, a degree of change in facial expressions of the user before and after invoking the suggested function;
• and
• transmit, to the server apparatus, a learning request requesting re-learning of the learned model when the evaluated degree of change in the facial expressions satisfies a predetermined condition.

A server apparatus comprising a communication interlace configured to communicate with a terminal apparatus and a controller, wherein the controller is configured to:

• receive, via the communication interface from the terminal apparatus, a suggestion request requesting a suggestion of a function to be invoked in the terminal apparatus, the suggestion request including face image data of a user of the terminal apparatus;
• determine the function to be invoked in the terminal apparatus by applying the face image data to a learned model;
• transmit via the communication interface to the terminal apparatus, a suggestion response that specifies the determined function to thereby cause the terminal apparatus to invoke the function;
• and
• in a case where a learning request requesting red earning of the learned model is received via the communication interface from the terminal apparatus, perform the re-learning of the learned model using a face image indicated by the face image data as an image for learning with the determined function as right function.

A terminal apparatus comprising.

• an image obtaining unit configured to image a user to thereby obtain a face image of the user;
• a control unit configured to invoke, among functions of the terminal apparatus, a function determined by applying the face image to a learned model;
• and
• a learning unit configured to perform re-learning of the learned model when a degree of change in facial expressions of the user before and after invoking the function satisfies a predetermined condition.
