Photographs in the three principle planes (frontal, sagittal, and axial) for both the SHV (panels A-C) and the PSA (panels D-F) task when holding the tactile bar that was positioned in front of the subject in the median sagittal plane. Rotations in the frontal plane for the SHV (panel A, frontal view) correspond to rotations in the axial plane for the PSA (panel D, top view). The view from top for the SHV (panel B, axial plane) matches the frontal view for the PSA (panel F, frontal plane) and the view from the side for the SHV (panel C, sagittal plane) parallels the side view for the PSA (panel E, sagittal plane).
