Visual images including intensive motions and the experience of virtual reality sometimes induce visually-indeuced motion sickness (VIMS). There are few studies that have objectively evaluated the effects of repetitive exposures to these stimuli on humans. In this study, an experiment was carried out in which the same video image was presented to human subjects three times. We evaluated changes of...
This paper presents a new hand motion assist robot for rehabilitation therapy. The robot is an exoskeleton with 18 DOFs and a self-motion control, which allows the impaired hand of a patient to be driven by his or her healthy hand on the opposite side. To provide such potential that the impaired hand is able to recover its ability to the level of a functional hand, the hand motion assist robot is...
The human watching moving images displayed on a wide-field display or screen sometimes suffers from the visually-induced motion sickness (VIMS) that induces symptoms related to the autonomic nervous system such as nausea, vomiting, and dizziness. The previous study indicated that the maximum cross-correlation coefficient (rhomax) between blood pressure and heart rate whose frequency components are...
