Pain and Fatigue in Desktop VR: Initial Results
Abstract
This paper describes a comprehensive experimental evaluation of a
two-handed free-form surface editor called THRED, which uses a pair of
Polhemus 3D trackers with added buttons in a complementary two-handed
style.
On top of the underlying free-form surface editor application was built
two other user interfaces that provide reasonable competition for the
two-handed style.
The second interface uses one button-enhanced 3D tracker in the
dominant hand, with the non-dominant hand selecting commands from the
keyboard.
The third style is a mouse-based interface that is a simplified clone
of the Alias modeler.
This user study evaluates these interfaces in terms of
pain and fatigue.
The results show that experienced minimal pain and fatigue with THRED,
an a par with that experienced in the mouse-based interface,
but there was statistically significant fatigue in the use of the
One-Handed interface.
The pain and fatigue surveys clearly indicate that THRED and the
Mouse-Based interface yield low discomfort, which contradicts the
established wisdom that bat-based interfaces are likely to be painful
or fatiguing to use.
