Results were analyzed similarly as for the first experiment (\secref{results}).
The \LMM were fitted with the order of the five vibrotactile positionings (\factor{Order}), the vibrotactile positionings (\factor{Positioning}), the visual hand rendering (\factor{Hand}), the {contact vibration techniques} (\factor{Vibration Technique}), and the target volume position (\factor{Target}), and their interactions as fixed effects and Participant as random intercept.
