Display Measurements. The Effects of HUD (Head-Up Displays) Glow on Visual Performance.

Abstract

This report examines residual glow in head-up displays. The contrast threshold work of Blackwell is used to estimate the detrimental effects of this glow on operator (pilot) performance. It is shown that even small amounts of glow can have serious detrimental effects on performance. The amount of detriment is a function of the level of glow, the operator's state of luminance adaptation, and the perceived contrast ratio between the target and the surround. The methods used in this report can be used to examine cases other than the ones presented in the report as required. (Author)
