\figref{ranks} shows the ranking of each visual hand rendering for the Push and Grasp tasks.

Friedman tests indicated that both ranking had statistically significant differences (\pinf{0.001}).

|
|
Pairwise Wilcoxon signed-rank tests with Holm-Bonferroni adjustment were then used on both ranking results (see \secref{metrics}):
|
|
|
|
\begin{itemize}
|
|
\item \textit{Push Ranking}: Occlusion was ranked lower than Contour (\p{0.005}), Skeleton (\p{0.02}), and Mesh (\p{0.03});
|
|
%
|
|
Tips was ranked lower than Skeleton (\p{0.02}).
|
|

|
|
This good ranking of the Skeleton rendering for the Push task is consistent with the Push trial results.
|
|
\item \textit{Grasp Ranking}: Occlusion was ranked lower than Contour (\p{0.001}), Skeleton (\p{0.001}), and Mesh (\p{0.007});
|
|

|
|
No Hand was ranked lower than Skeleton (\p{0.04}).
|

|
|
A complete visual hand rendering seemed to be preferred over no visual hand rendering when grasping.

\end{itemize}
