Design outcomes

Primary

Measure	Time frame
Primary: • Retinal slip velocity in °/s, the movement of the eye relative to the image.	—

Secondary

Measure	Time frame
Secondary: • Saccade and smooth pursuit amplitude and latency as a reference for the accuracy of oculomotor response when viewing a moving image with a stationary head. • Hearing threshold in dB as a reference for the integrity of the audiovestibular end organ. • Speech discrimination in % as a reference for the integrity of the audiovestibular end organ. • Visual acuity in % as a reference for the integrity of the input from the visual system. • DHI score, ERGO score, and VAS score for documentation of the experience of balance complaints.	—
