Abstract

Recent advances in AI technologies have led to the development of more innovative applications prioritizing human well-being across various dimensions, including emotional, cognitive, and social aspects. In this talk, I will present our efforts to leverage three technologies—personalized recommendation systems, conversational AI, and generative AI—to create personal assistants that support music exploration, self-awareness, and reminiscence. Our studies illuminate how different interaction techniques and user characteristics influence trust in and willingness to use these AI assistants. Additionally, we will discuss design considerations that can enhance the system's effectiveness in promoting mental well-being by tailoring its functionalities and user interactions to the preferences and needs of diverse populations, including young people and older adults. By integrating insights from multiple disciplines—such as AI, human-computer interaction, psychology, and cognitive sciences—our ultimate goal is to develop more robust AI-empowered systems that actively support mental health.
