Field of View Requirements

The results presented in Subsection 5.1.2 suggest that a longer vertical field-of-view for the VV Sport display is necessary, at least for more severely akinetic patients. Figure 6.1 indicates the suggested minimal extension to the field-of-view for the VV Sport. Since the minimal effective vertical field-of-view may be a function of ambulation speed (with more distant cues necessary to sustain running), the optimal design may be somewhat longer than that suggested in this frame.

The possible advantage of a display which is wider, as well as longer, is discussed in Subsection 6.4.1.
