based on 'kansei' (sensitivity) and
intuition of artists
based on analysis of human behaviors and
utilization of image/speech processing

Interactive Environment
• EEnvironments are fixed
• EHumans select environments
depending on communications.
• EEnvironments are flexible
• EEnvironments vary depending
on communications
