Introduction

Hirotaka Osawa is deeply involved in the field of “human-agent interaction (HAI),” which designs interactions between humans and artificial objects that are recognized as social beings. His research focuses on artificial intelligence technology, robots, and virtual reality related to human social intelligence. He also explores the use of storytelling to facilitate human-to-human connection and the concept of science fiction prototyping. His research aims to enhance the understanding and development of social intelligence in artificial agents, making them more approachable and effective in human environments. His research has an interdisciplinary nature, combining elements of psychology, cognitive science, and technology to create innovative solutions for real-world applications. He is one of the leading experts in HAI research, providing insights into how humans and artificial agents can coexist and interact harmoniously, and improving the quality of human-agent interaction in a variety of fields. He is also one of the leading experts in engineering research on science fiction, and is the head of Japan's first academic research organization for science fiction. His research focuses on social intelligence, and he is involved in research on interpersonal agent intention estimation and cooperation, social simulation, and narrative.
