Effects of Headgear and Visual Angle on Head Rotation Spectral Characteristics.
Abstract
Dynamic characteristics of the unrestrained human head movement control system are measured as a function of headgear weight and size of the stimulus trajectory envelope. The coherence, gain and phase spectral characteristics are unaffected by variations in the weight of the helmet and associated head line-of-sight measurement hardware; however, a gain amplitude nonlinearity related to stimulus visual field size is shown to exist.
