Results were analyzed similarly as for the first experiment (\secref{results}).

The LMM were fitted with the order of the five vibrotactile positionings (Order), the vibrotactile positionings (Positioning), the visual hand rendering (Hand), the {contact vibration techniques} (Technique), and the target volume position (Target), and their interactions as fixed effects and Participant as random intercept.
