Quantifying Visually Induced Motion Sickness (VIMS) During Stereoscopic 3D Viewing Using Temporal VIMS Rating

Visually induced motion sickness (VIMS) is evoked by conflicting motion sensory signals within the brain. Use of the simulator sickness questionnaire (SSQ) or postural stability measures to quantify one’s VIMS experience only measures the changes between preand post-experiment. The motion sickness susceptibility questionnaire (MSSQ) is widely used to measure individual’s sensitivity to motion sickness, but its applicability to VIMS has not been proven. We are introducing a novel VIMS susceptibility measure by combining measures of the subject’s “sensitivity” and “endurance” to VIMS. The proposed VIMS susceptibility measure was tested for various VIMS inducing conditions, and demonstrated its effectiveness by conducting both between-subjects and within-subject comparisons for different VIMS conditions. c © 2017 Society for Imaging Science and Technology.

Such symptoms are similar to those of motion sickness experienced in cars or boats. When they are mainly induced by visual motions, these symptoms are referred to as visually induced motion sickness (VIMS).
