Virtual Character Interaction Memory for Personalized, Consistent Replies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing open-domain conversation systems in virtual characters lack personalization and consistency in interactions due to static settings and limited memory, leading to suboptimal user experience.
Innovation Solution
An interaction method that generates interaction text for virtual characters based on character information including setting and memory information, utilizing long-term and short-term memory to personalize and maintain consistency in conversations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If static character settings are used in virtual characters, then the system complexity is reduced, but the personalization and consistency of interactions deteriorate
Solution Approach 1:
The character information is segmented into character setting information (static personality, appearance) and memory information (dynamic historical events and conversations). This segmentation allows the system to maintain manageable complexity while enabling personalized interactions through the combination of static and dynamic components.
Solution Approach 2:
The system transitions from static character settings to dynamic character representations by incorporating memory information that evolves with each interaction. The memory information is updated based on historical events and conversations, making the virtual character adaptive and consistent over time without requiring complete system redesign.
2Device complexity
If limited memory is used for virtual characters, then the device complexity is reduced, but the consistency of interactions deteriorates
Solution Approach 1:
Memory information is segmented into event information (historical events involving the character) and conversation information (past dialogues). This segmentation allows selective retrieval of relevant memory based on current interaction context, maintaining consistency without requiring access to all historical data simultaneously.
Solution Approach 2:
The system implements feedback by updating memory information based on current interactions. Historical events and conversations are recorded and fed back into the character's memory profile, enabling consistent responses in subsequent interactions while managing complexity through selective memory access.
