Emotionally Adaptive LLM Alignment: Integrating Biometric and Affective Feedback for Deep Personalization

Building on advances in affective computing and emotion recognition (Younis et al., 2024; Balsara et al., 2024), this research proposes a cross-disciplinary synthesis: personalized LLMs whose alignment is guided by both explicit user feedback and implicit affective cues. Unlike current user modeling approaches, which largely rely on behavioral or preference histories (Shang et al., 2024; Doddapaneni et al., 2024), this framework would use multi-modal emotion recognition as an additional signal—adjusting tone, content, and even safety responses in emotionally charged scenarios. For example, if a user’s biometric signals indicate frustration or anxiety during a conversational task, the LLM could adapt its responses for greater empathy or clarity. This marriage of affective computing and LLM alignment could revolutionize user satisfaction, especially in domains like education, therapy, or customer support, and address limitations of text-only personalization.
