We developed learning environment for stars and constellations with finger pointing under real night sky.This environment has some functions. First function is star name telling function. When a learner points a finger at a star with the sensor on his/her finger top, the system tells him/her name of the star and constellation with voice. Then, second(More)
It is required to improve reliability and economical efficiency of nuclear power plant (NPP) at the same time. There is a room to achieve this goal by introducing state-of-art information technology into maintenance work of NPP. In this study, a maintenance support system using Augmented Reality (AR) has been proposed to support water system isolation task(More)
Y2O3-stabilized tetragonal ZrO2 polycrystal (Y-TZP) has been known to be an excellent structural material with high strength and toughness since the pioneering study by Garvie et al. in 1975. However, Y-TZP is not considered an environmental or biomedical material because it undergoes an inherent tetragonal-to-monoclinic (T → M) phase transformation in(More)
