Useful field of view
In human vision, the useful field of view (or UFOV) is the visual area over which information can be extracted at a brief glance without eye or head movements.〔Ball, K., V.G. Wadley, and J.D. Edwards, Advances in technology used to assess and retrain older drivers. Gerontechnology, 2002. 1(4): p. 251-261.〕 Generally UFOV size decreases with age,〔Sekuler, A.B., P.J. Bennett, and M. Mamelak, Effects of aging on the useful field of view. Exp Aging Res, 2000. 26(2): p. 103-20.〕 most likely due to decreases in visual processing speed, reduced attentional resources, and less ability to ignore distracting information.〔 UFOV performance is correlated with a number of important real-world functions including risk of an automobile crash. Performance can be improved by computer based training.
== History ==
UFOV assessment and training programs were primarily developed by Dr. Karlene Ball of the University of Birmingham, Alabama, and Dr. Daniel Roenker of Western Kentucky University. The first versions of the assessment and training programs were produced more than 20 years ago.〔Sekuler, R. and K. Ball, Visual localization: age and practice. J Opt Soc Am A, 1986. 3(6): p. 864-7; Ball, K.K., et al., Age and visual search: expanding the useful field of view. J Opt Soc Am A, 1988. 5(12): p. 2210-9.〕 These programs were originally made available through Visual Awareness Inc. In 2008, Posit Science acquired Visual Awareness and worked with Dr. Ball and Dr. Roenker to produce an updated version of UFOV training. The latest version is known as Road Tour or Double Decision and is incorporated into Posit Science’s DriveSharp〔(【引用サイトリンク】title=Drivesharp - Think Faster on the Road - Posit Science - Your Brain Health Headquarters )〕 and BrainHQ〔(【引用サイトリンク】title=Attention to Detail Exercises, Double Decision Exercise - Posit Science )〕 training programs.
