Visual simulation of night vision goggles in a chromakeyed, augmented, virtual environmentBeilstein, Del L. 06 1900 (has links)
Approved for public release; distribution is unlimited. / This thesis done in cooperation with the MOVES Institute. / Despite data indicating more human error accidents occur during NVG flight than in any other flight mode, there are very few simulation tools available to aviators at the unit level that aid them in learning or practicing NVG flight tasks. This thesis examines the potential for a Chromakeyed Augmented Virtual Environment (ChrAVE), consisting only of Commercial-Off-The- Shelf (COTS) hardware, to be used as an NVG flight training platform. It also examines whether or not physically-based light calculations are necessary to produce adequate visual representation of simulated NVG imagery. Twelve subjects performed simulated low-level NVG flight navigation tasks in the ChrAVE. Treatments included questionnaires, vision tests, variation of the physics-based component of the NVG imagery, and performance of an evaluation task that compares standard thresholds between day and NVG navigation. Analysis of data and subject feedback indicate that the ChrAVE has potential as an NVG flight training device, and that physically-based calculations may not be necessary to achieve simulated NVG imagery that is adequate for training. The data also supports the existence of a substantial difference in the subjective evaluation standard between navigation performances based on flight condition. / Captain, United States Army

Determination of human visual capabilities in the identification of the color of highway signs under a combination of vehicle headlamp and high intensity discharge light sourcesSaremi, Ahmad Reza 02 August 1990 (has links)
A standardized color code is used to aid the driver in the prompt
recognition of highway signs. At night, these signs are illuminated by
various light sources including the headlights and other fixed light
sources. These light sources may distort the appearance of the colors
of the signs at night.
The first objective of this study was to provide information about human
capabilities with respect to the recognition of different colors under
daytime and nighttime lighting. The second objective was to examine the
effect of changing the specifications for highway colors from the
Federal Highway Administration (FHWA) standards to the American National
Standards (ANSI) safety color specifications.
A laboratory experiment was conducted in which subjects named the
perceived colors of retroreflective signs viewed under daytime and
nighttime lighting. Forty subjects from four different age groups
representing the driving population participated in the study. Three
color samples (red, orange, and yellow) in three different grades
(engineering grade, high intensity grade, and diamond grade), and two
different color specifications (FHWA and ANSI) were used. Four
different fixed light sources (clear mercury, coated mercury, coated
metal halide, and high pressure sodium) were used for illuminating the
signs. For the nighttime condition, two headlights were used (metal
halide and tungsten halogen). Daytime lighting was simulated using a
fluorescent D-65 light source. Response times as well as correct
responses for naming the colors were collected for each subject.
Significant differences were found for nighttime versus daytime viewing
of the signing materials. In general, for nighttime viewing, red and
orange colors were identified faster than yellow color samples. In most
cases, FHWA colors were identified significantly more accurately and
faster than the ANSI colors. The coated metal halide headlight
performed better than the other fixed light sources. There was no
significant difference found between the tungsten halogen and the metal
halide headlights. / Graduation date: 1991
