Seasickness and virtual reality sickness are known to cause equilibrium dysfunction due to a "mismatch" between somatosensory (mainly through skin and muscle sensation) and visual sensations, but it is known to become accustomed (adaptation). Responses adapted by somatosensory or visual sensations are referred to as adaptive phenomena, which we examined using rotation testing and a flat and spherical screen with projected black and white stripes, as well as visual vestibular inconsistency stimulation. The results of our previous studies showed that a flat screen under off-vertical axis rotation (OVAR) and a spherical screen under earth vertical axis rotation (EVAR) were suitable for visual vestibular inconsistency stimulation. Visual stimulation of linear motion was suitable for otolith-ocular reflex (OOR) and visual stimulation of rotational angular rate motion for semicircular canal-ocular reflex (ScOR).
The purpose of this study is to reaffirm previous research by using computer graphic techniques to perform pseudo-linear and pseudo-rotational visual stimuli. The eventual goal is to obtain the basic data necessary to appropriately select the modality of visual stimulation to be used during rehabilitation, depending on the site of the disorder, in cases where the semicircular canal is impaired or the otolith is impaired.

Phase I
Using the created HMD, perform pseudo-linear and pseudo-rotational visual stimulation on the subject. Subjects will be asked to complete a questionnaire immediately following the study. Evaluate the validity of the stimuli by asking the participants to describe whether they feel as if they moved reality in a straight line when they experienced the pseudo-linear visual stimuli, and whether they feel as if they rotated reality when they experienced the pseudo-rotational visual stimuli ("felt", "felt a little", or "did not feel").
Using the created HMD, perform pseudo-linear and pseudo-rotational visual stimulation on the subject. Subjects will be asked to complete a questionnaire immediately following the study. The participants will be asked to describe whether nausea or other symptoms appeared during the test ("felt", "felt a little", or "did not feel") to evaluate safety.

Device,equipment |
The participants will wear a head-mounted display (HMD).
Pseudo-linear and pseudo-rotational visual stimuli are added on the HMD, and the visibility is verified by a questionnaire method. The test time is approximately 30 minutes. The test will be conducted only once per subject.
