Recent development of information technology is making electric household appliances computerized and networked. If the environments surrounding us could recognize our activities indirectly by sensors, the novel services, which respect our activities, can be possible. In this paper, we propose human activity recognition system, which infers the next human(More)

Recent advances in information technology are making electric household appliances computerized and networked. If our environments could intuit our activities , e.g., by sensors, novel services taking anticipated actions into account would become possible. We propose activity recognition that infers a subject's next action based on previously observed(More)
In this paper, we propose the human behavior detection and activity support environment Vivid Room. Human behaviors in Vivid Room are detected by many kinds of sensors embedded in the room (i.e. magnet sensors for doors/drawers, micro-switches for chairs, ID-tags for humans.) and that information is collected by sensor server via RF-tag system and LAN. In(More)

Immunoglobulin G4-related disease (IgG4-RD) is a recently discovered systemic condition, in which various organ manifestations are linked by a similar histological appearance. Our knowledge of this condition is still fragmented, as most studies have examined only a few dozen patients or focused on a particular organ manifestation. This study was conducted(More)
We propose a new concept, raison d'ˆ etre objects, and a new ware, cyber-hearth, that affords snugness in face-to-face communication in a shared informal place such as a refreshing room or lounge. We carried out observation experiments on the behavior of individuals in such a place and found interesting tendencies: most people behave unconsciously to pay(More)
A generalized asynchronous cellular automaton-based neuron model is a special kind of cellular automaton that is designed to mimic the nonlinear dynamics of neurons. The model can be implemented as an asynchronous sequential logic circuit and its control parameter is the pattern of wires among the circuit elements that is adjustable after implementation in(More)
