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.

Figure 3: Time-varying factors model with trigger factors and accumulation factor (adapted from [7]).

Mentions: In rehabilitation, repetitive task practice is a common approach to recover impaired functions. To achieve successful recovery, practice and rest periods and levels of training should be carefully controlled depending on individual differences. Figure 3 demonstrates a model in which the progress in recovery consists of an accumulation factor and trigger factors [7]. An accumulation factor has a long time scale because it relates to background ANA, while trigger factors have a short time scale because of the relatively fast sensory processing in the brain.
