Sensation of presence and cybersickness in applications of virtual reality for advanced rehabilitation.

Kiryu T, So RH - J Neuroeng Rehabil (2007)

Bottom Line: Virtual stimuli can enlarge sensation of presence, but they sometimes also evoke unpleasant sensation.In order to safely apply augmented and virtual reality for long-term rehabilitation treatment, sensation of presence and cybersickness should be appropriately controlled.In particular, the influence of visual and vestibular stimuli on cardiovascular responses are reported in terms of academic contribution.

ABSTRACT
Around three years ago, in the special issue on augmented and virtual reality in rehabilitation, the topics of simulator sickness was briefly discussed in relation to vestibular rehabilitation. Simulator sickness with virtual reality applications have also been referred to as visually induced motion sickness or cybersickness. Recently, study on cybersickness has been reported in entertainment, training, game, and medical environment in several journals. Virtual stimuli can enlarge sensation of presence, but they sometimes also evoke unpleasant sensation. In order to safely apply augmented and virtual reality for long-term rehabilitation treatment, sensation of presence and cybersickness should be appropriately controlled. This issue presents the results of five studies conducted to evaluate visually-induced effects and speculate influences of virtual rehabilitation. In particular, the influence of visual and vestibular stimuli on cardiovascular responses are reported in terms of academic contribution.

Mentions: The autonomic nervous regulation would be evaluated during a recovery phase because it regulates cardiovascular functions after extensive exercise or stress. That is, there is a time delay between the incoming stimuli for sensory systems and the corresponding autonomic regulation. Moreover, there is a large difference in time-scale between sensory activity and autonomic nervous activity (ANA) (Fig. 2). In particular, sensory activities work within a few tens of milliseconds, whereas ANA takes several seconds. Due to such a large difference in time-scale, researchers have studied either one or the other, but not both.
