Preliminary research on application of virtual reality as optical stimulation in videonystagmography

The paper presents a research on the utilization of a virtual reality as means of stimulation during a videonystagmography examination. The main aim of the research was to test whether an optical stimulation generated by means of virtual reality presented in a helmet-mounted display is applicable to the videonystagmography examination. Eye position was recorded by an infrared camera mounted in virtual reality head-set. Visual stimulations were first performed on a LCD display mounted in VR goggles and then on a LCD monitor. Tracking of a moving field was a subject's task. Target horizontal and vertical jumps were used for calibration. Visual stimuli applied were pendulum target movement and moving vertical stripes. The results of tests showed that pupil positions registered during the virtual stimulation were consistent with those registered during the traditional stimulation.
