With respect to the real hand position, it causes a distance error in the displayed virtual hand position, and thus a delay in the triggering of the vibrotactile signal.

The first manipulation task consists in pushing a virtual object along a real flat surface towards a target placed on the same plane (\figref{method/task-push}).
The virtual object to manipulate is a small \qty{50}{\mm} blue and opaque cube, while the target is a (slightly) bigger \qty{70}{\mm} blue and semi-transparent volume.

At every repetition of the task, the cube to manipulate always spawns at the same place, on top of a real table in front of the user. At every repetition of the task, the cube to manipulate always spawns at the same place, on top of a real table in front of the user.
