The vestibulo-ocular reflex is an involuntary movement of the eye adjustment that serves to stabilize retinal images during head movements. The vestibulo-ocular reflex consists of compensatory eye movements in the opposite direction to the head rotation and rapid reorientation movements, usually in the same direction as the head movement. This dissertation presents a proposal of a low cost and high-speed device for recording head movements (acceleration and positioning) during the vestibulo-ocular reflex examination. Measurement of the head movements were used for the characterization the stimuli applied by the instrument to quantify human balance. Data collections were performed simultaneously, extracted from a subject using the device developed in conjunction with a golden device in a specialized laboratory for movement analysis. Subsequently, these data were analyzed to verify the convergence between the proposed device and the standard equipment. The results obtained demonstrate the technical feasibility for future use in clinical applications.
