In this thesis we studied the perceived arm fatigue of the users of mid-air interaction systems such like VR headsets through multiple experiments. We focused on the variation of arm fatigue due to:
- the hand synchronisation (the use of one or two hands synchronised or not).
- the rhythm and the use of a sound to highlight it.
- the use of control/display ratio during musical interaction.
We contributed through some design guidelines and ideas for future work.
