System

A system comprising:

• circuitry configured to:
• receive facial configuration information from a terminal device via a communication interface, encode the facial configuration information as numerical facial feature data, and generate a plurality of facial image data items using a generative AI model conditioned on the numerical facial feature data;
• determine when a count of stored facial image data items reaches a predetermined threshold, aggregate the numerical facial feature data to generate feature description text, and construct a prompt sentence incorporating the feature description text;
• input the prompt sentence to a text generation AI model to generate story content, acquire emotion information representing an emotional state of a participant, and adjust the story content based on the emotion information to generate presentation data;
• and
• transmit the presentation data and the facial image data items to a virtual space display device via the communication interface for display in a virtual reality space.

A method comprising:

• causing a terminal device to provide a user interface that allows a participant to select facial components and combine the facial components to generate facial configuration information via a communication interface coupled to a packet-switched network, receiving the facial configuration information as structured data from the terminal device, encoding the structured data as numerical facial feature data, and storing the numerical facial feature data as feature vectors in a memory;
• inputting the numerical facial feature data as conditioning information together with random information to a generative AI model, executing the generative AI model to generate a plurality of facial image data items similar to the numerical facial feature data, and storing the plurality of facial image data items and corresponding numerical facial feature data in the memory;
• determining whether a number of the facial image data items stored in the memory is greater than or equal to a predetermined threshold and, when the number is greater than or equal to the predetermined threshold, aggregating the corresponding numerical facial feature data to generate feature description text and generating a prompt sentence comprising the feature description text;
• inputting the prompt sentence to a text generation AI model, executing the text generation AI model to generate story content based on the plurality of numerical facial feature data, acquiring emotion information indicating an emotional state of the participant, and adjusting contents of at least one of the prompt sentence and the story content based on the emotion information to generate adjusted story content as presentation data;
• and
• transmitting the presentation data and the plurality of facial image data items to a virtual space display device via the communication interface so that the virtual space display device displays the adjusted story content and the plurality of facial image data items in a virtual reality space.
