Virtual Character

Virtual characters are increasingly sophisticated digital representations designed to interact with humans, primarily leveraging large language models (LLMs) to generate realistic and contextually appropriate behaviors and dialogue. Current research focuses on enhancing the realism and adaptability of these characters, including aligning their behavior with visual personas, simulating diverse personality traits, and improving cultural sensitivity through techniques like persona-based training and retrieval-augmented control. This field is significant for its potential applications in various domains, such as education, entertainment, and mental health support, while also raising important ethical considerations regarding bias, manipulation, and privacy.
