FIG. 2

During each one of the three testing motions (yaw rotation, y-translation, and roll tilt), participants were subjected to motion stimuli corresponding to single cycles of sinusoidal acceleration. An example of one cycle of sinusoidal acceleration of yaw rotation is shown in the bottom figure, and this corresponds to cosine bell velocity and sigmoidal displacement profiles. The example shown shows a 1-Hz motion (frequency used in yaw rotation and y-translation motions) with a displacement of 1 °.
