\subsection{Manipulation Tasks and Virtual Scene}
\label{tasks}
\begin{subfigs}{tasks}{%
Experiment \#1. The two manipulation tasks:
}[
\item pushing a virtual cube along a table towards a target placed on the same surface; %
\item grasping and lifting a virtual cube towards a target placed on a 20-cm-higher plane. %
Both pictures show the cube to manipulate in the middle (5-cm-edge and opaque) and the eight possible targets to
reach (7-cm-edge volume and semi-transparent). %
Only one target at a time was shown during the experiments.%

The cube to manipulate is in the middle of the table (5-cm-edge and opaque) and the eight possible targets to reach are arround (7-cm-edge volume and semi-transparent).
Only one target at a time was shown during the experiments.

Following the guidelines of \textcite{bergstrom2021how} for designing object manipulation tasks, we considered two variations of a 3D pick-and-place task, commonly found in interaction and manipulation studies \cite{prachyabrued2014visual, maisto2017evaluation, meli2018combining, blaga2017usability, vanveldhuizen2021effect}.
