Viewing yellow-green displays, like those in night vision goggles, causes color aftereffects. Target color naming time depends on adaptation and target colors, suggesting redundant coding for cockpit displays.

Area of Science:

  • Visual perception
  • Experimental psychology
  • Human factors engineering

Background:

  • Night vision goggles (NVGs) often use a yellow-green display.
  • Understanding visual aftereffects is crucial for human-computer interaction and display design.
  • Chromatic aftereffects can influence color perception and task performance.

Purpose of the Study:

  • To investigate the chromatic aftereffects of viewing a simulated night vision goggle display.
  • To determine how adaptation field color and target color affect color naming times.
  • To provide recommendations for optimizing cockpit display design.

Main Methods:

  • A visual perception experiment was conducted with eight subjects (six female, two male).
  • Subjects performed a color-naming task after viewing either a yellow-green or white adaptation field on a CRT display.

  • The time to name the color of small, sequentially presented targets was measured.

    • Main Results:

    • Color naming time was significantly influenced by the color of the adaptation field.
    • Target color also demonstrably affected color naming times.
    • A significant interaction was found between the adaptation field color and the target color.

    Conclusions:

    • The chromatic properties of simulated night vision goggle displays induce measurable aftereffects.
    • Display luminance attenuation effects warrant further investigation.
    • Redundant coding of color cockpit displays is recommended to mitigate potential perception errors.
