This paper proposes human behavior perception compound between passive perception and active perception. Human behavior is stored in a database for creating the life log to realize visualization system for supporting elderly people using iPad. First, we discuss the life log system configuration based on informationally structured space. We apply sensor network and smart phone for measuring human behavior to realize passive perception, and we also apply conversation system for conducting communication between robot partner and human to realize active perception. Next, we explain the database system that constructs informationally structured space. The cloud database is used to share the elderly people's life log information with the elderly people's family and caregivers through the visualization system. Finally, we discuss the usability of the Visualization System through experimental results.
