Problem: Field sequential color is a highly effective technique for presenting a high resolution, wide field of view color display to the viewer of head-mounted displays used in training & simulation systems and virtual reality entertainment systems. Unfortunately, objects moving at a high angular rate through the field of view will appear to "break up" into multiple color objects- an intolerable feature in high performance displays.
Solution: A collaborative four-party research project was initiated to determine if this problem could be mitigated in some way. Tests conducted by and at Wright State University and by ABCD Technology at the Air Force Research Laboratory's Air Vehicles and Human Effectiveness Directorates ascertained that the color breakup effect can be completely eliminated by field-rate update of objects moving in the display, for targets of all sizes and up to maximum discernable target velocities. These findings eliminate a major concern regarding field sequential color, and thus enable- given sufficient computational resources- the development color head-mounted virtual reality displays with resolutions and fields-of-view unattainable with other color techniques.
