A linear physiological visual-vestibular interaction model for the prediction of motion sickness incidence

Abstract

This thesis proposes a linear model based on human physiology for the explanation of the Motion Sickness Incidence (MSI) data found in previously reported experiments. The major human sensory systems taken into account are vestibular, visual, and the interaction between these two. The model is validated against the previous descriptive model and the corresponding experimental data. The proposed model predicts MSI with adequate precision (less than Å 5%) in the frequency range between 0.07 Hz and 0.25 Hz. The difference between the proposed model and the previous descriptive model is increased at the outer frequency regions of the data.
