Motion compensation Influence on field Sequential color Display Motion Artifacts

motion.jpg (19257 bytes)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.


  • This effort could lead to development of commercial display products that eliminate or reduce the field sequential artifacts commonly observed by viewers.
  • In addition, a better understanding of the physics relating to field sequential color displays will result.
  • In the long term, it will improve displays in the simulation and virtual realities industries.

Current Status:

  • Two research papers have been prepared and presented.
  • The Cooperative Research and Development Agreement (CRADA) has been extended to permit additional research when the collaborators obtain grant funding to cover their participation.
  • Related evaluation is planned using operational Air Force pilots.
If you have any questions about this Cooperative Research and Development Agreement or are interested in getting more information about technology transfer and CRADA projects, please contact Jim Singer at Wright Technology Network (937) 253-0217 or CRADA@wtn.org
