\section{Results}
\label{results}

Results were analyzed similarly as in the user study of the visual hand augmentations (\secref[visual_hand]{results}).
The \LMM were fitted with the vibrotactile positionings (\factor{Positioning}), the visual hand augmentation (\factor{Hand}), the {contact vibration techniques} (\factor{Vibration Technique}), the target volume position (\factor{Target}) and their interactions as fixed effects, as well as by-participant random intercepts.
Depending on the data, different random effect structures were tested.
Only the best converging models are reported, with the lowest Akaike Information Criterion (AIC) values.
