Adeia filed 1 patent in 1 category: AI & Machine Learning (1). The filing covers a system that uses relationship graphs and large language models to generate dynamic NPC personalities in video games.
This AI & Machine Learning technology allows non-player characters throughout a game world to respond contextually to player actions rather than following predetermined scripts.
The AI & Machine Learning patent tackles a common limitation in game design where only central characters receive detailed scripting while background NPCs remain generic. The system creates a web of relationships between characters and employs large language models to generate contextually appropriate dialogue for any NPC the player encounters. To maintain narrative coherence and prevent characters from revealing information they shouldn't know, the technology constrains what each NPC can discuss based on two factors: their relationship strength to other characters in the graph, and the player's current progression through the game. This approach aims to make entire game populations feel reactive and personalized without requiring developers to manually script thousands of individual interactions.
