Altering the colors displayed impacts applied task efficacy when laser eye protection is required

Area of Science:

• Human-Computer Interaction
• Visual Perception
• Defense Technology

Background:

• Development of color visual displays for defense applications is increasing.
• Integration of laser eye protection (LEP) necessitates careful consideration of display color palettes.
• Current standard color palettes may lead to performance issues in applied contexts.

Purpose of the Study:

• To evaluate the impact of a customized, reduced color palette on visual display performance.
• To compare a five-color custom palette against a standard seven-color palette in a driving simulation task.

Main Methods:

• Participants performed a driving simulation task involving the identification of colored symbology.
• Two color conditions were tested: a standard seven-color palette and a custom five-color palette.
• Performance was measured by accuracy in identifying symbol colors.

Main Results:

• The standard color palette exhibited color confusions, particularly between cyan and green.
• The custom five-color palette significantly reduced color confusion.
• Overall accuracy was higher with the custom palette (94.80%) compared to the standard palette (88.17%).

Conclusions:

• A customized, reduced color palette can enhance performance in visual display tasks.
• Careful selection of symbology colors is crucial when integrating laser eye protection (LEP).
• Optimizing color palettes can mitigate performance decrements in defense-related visual tasks.
