Spatial disorientation or the loss of situational awareness has been identified as the primary or secondary cause of 15-25% of all fatal military aircraft accidents. One of the promising recent attempts to combat disorientation has focused on the peripheral vision horizon device (PVHD). The current set of experiments indicate that when two fixed-length PVHD horizon line segments (straight line with missing central segment) are progressively moved outward, away from central vision, the ability to track the horizon does not improve but diminishes. Tracking performance was not optimal when the horizon line segments were presented to retinal areas having the highest visual rod density as speculated in our initial report. Improvements in compensatory tracking with PVHD presentations appear to be related to absolute size of the horizon.
