Average (± 1 StdDev) errors of SHV (haptic vertical) for both the tactile rod (panel A) and the tactile plate (panel B) are illustrated. Adjustments for right- and left-handed subjects are illustrated separately and errors of CW rotations are compared with those of CCW rotations. The starting position of the device and the required direction of rotation (CW vs. CCW) are also illustrated in inlets on the top. Black circles refer to adjustments with the right hand, gray squares to adjustments with the left hand. Trial types with significant errors relative to zero (t-tests) are marked (**).
