5. Verifying the Sleep-Inducing Effect of a Mother’s Rocking Motion in Adults

Hiroaki Shibagaki, Keishi Ashida, Yoshifumi Morita, Ryojun Ikeura, Kiyoko Yokoyama
Pages: 129 - 133
Previously, we concluded that a mother's rocking motion is the most effective motion for inducing sleep in adults. We call it the candidate rocking motion. In this study, we confirm that the candidate rocking motion is more effective in inducing sleep than using no rocking motion. Moreover, we find that...

6. The Suitable Timing of Visual Sensing in Error Recovery Using Task Stratification and Error Classification

Akira Nakamura, Kazuyuki Nagata, Kensuke Harada, Natsuki Yamanobe
Pages: 134 - 137
Judgment of errors for recovery is performed during execution of the system. Ideally, it is desirable for the judgment to be performed at several times. However, in that case, many sensors would be needed and it would lead to disturbing the workflow. Therefore, it is important to be able to judge an...
