Multi-dimensional effects in galvanic vestibular stimulations through multiple current pathways

This study describes multi-dimensional effects in galvanic vestibular stimulations through multiple current pathways. In this study, we propose a model of three current pathways for GVS. To confirm the presence of the pathways, DC resistances through head were measured in Experiment 1. In Experiment 2, the sway of standing subject was measured as the multi-dimensional effect of GVS through the three pathways. A new yaw rotational sway response was found by the novel method of GVS using four electrodes. The new method is available to realize a multi-dimensional equilibrioceptional display by GVS.
