The ability to quickly construct a human activity observation system is necessary in order to conduct field research on human activities. The authors have developed an ultrasonic 3D tag system, which is a type of location sensing system for observing human activities. The present study attempts to establish a systematic method for quickly constructing an(More)
This paper proposes a system for quickly realizing a function for robustly detecting daily human activity events in handling objects in the real world. The system has three functions: 1) robustly measuring 3D positions of the objects; 2) quickly calibrating a system for measuring 3D positions of the objects; 3) quickly registering target activity events;(More)
We established a new computerized EEG filing system, in which an EEG machine was connected to an EEG filing unit which consisted of a personal computer with a 32 bit CPU, 18 channel analog -to-digital and digital-to-analog converters, and a magneto-optical disc driver. This system has the following merits. The system was space-saving, the space required to(More)
