Dominant Versus Non-Dominant Eye

The qualitative trials did not look carefully at the question of whether the VV images should be provided to the dominant or the non-dominant eye. We tried both eyes for both subject with positive results, but we don't have data on their relative effectiveness. One would prefer to use the non-dominant eye if possible, since it makes the display less intrusive. However, eye dominance effects may interact with field-of-view effects as the display evolves (see Subsection 6.3 below).

A careful study will be necessary to tease apart the issues here, since one must also consider the fact that Parkinson's disease typically affects one side more strongly than the other. This may also play a role in determining the appropriate eye for image presentation.
