The Interaction Laboratory was established in 1999 to investigate the future of human computer interactions and digital lifestyles. Expanding the previous real-world user interface research within the Sony Computer Science Laboratories, we are currently working on fundamental technologies, including software architectures, hardware architectures, and sensor architectures, that will be needed to realize natural and intuitive interactions between the human, as a physical entity, and the information environment, as a digital entity. In addition to technology-oriented activities, we are also seeking a deeper understanding of human life itself, through cognitive research, and design and lifestyle studies. The Interaction Laboratorys fundamental goal is to establish symbiotic relationships between humans and technology.
