Vestibulo-Ocular Reflex model based on 6DOF-SVC model

Abstract

Many mathematical models have been proposed for Vestibulo-Ocular Reflex (VOR) of human from head movement. It is known that, the model accuracy of these conventional models decrease when mental task is added to the human. On the other hand, 6DOF-SVC model, a mathematical model of motion sickness due to vestibular sensory system, includes a sub-model block representing the prediction accuracy of their own body movement, which is thought to be affected by the mental task. Therefore, toward description of the influence of mental task on VOR, the proposed VOR model connects the estimated single of body movement in 6DOF-SVC model to the VOR calculation path. The parameter identification experiments were coducted which to compare the accuracy of the proposed model with that of the conventional model. We found that the accuracy of the proposed model is as high enough to describe human VOR as the conventional model.
