The National Institute of Information and Communications Technology of Japan completed a real-life testbed, called the "ubiquitous home," for home context-aware service experiments in 2004. From the viewpoint of sensor ubiquity, the Ubiquitous Home is superior to other similar testbeds. At the Ubiquitous Home, experimenters can collect real-life data as if living in their own house, not in a laboratory. This paper introduces an overview and detailed sensor arrangement of the Ubiquitous Home. Two cases from several progressing experiments are also presented. The first case is on connecting networked appliances; the second concerns the combination of wearable devices and the Ubiquitous Home sensors to record user behavior.
