Color Vision

701
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

    Area of Science:

    • Human-Computer Interaction
    • Computer Graphics
    • Perception Science

    Background:

    • Optical see-through head-mounted displays (OHMDs) integrate digital information with physical environments.
    • Existing color management in OHMDs often relies on green, limiting design flexibility.
    • There is a need for broader, empirically validated color guidelines for OHMDs.

    Purpose of the Study:

    • To empirically evaluate color perception and usability under various OHMD conditions.
    • To develop comprehensive color guidelines for OHMD interface design.
    • To expand the usable color palette for augmented reality experiences.

    Main Methods:

    • An empirical study involving 30 participants evaluating 216 colors.
    • Assessment of color clarity and comfort across different hues, devices, and lighting.
    • Iterative refinement of guidelines through a design workshop with 12 professionals.

    Main Results:

    • Identification of clear and comfortable saturation and brightness ranges for various hues.
    • Quantification of color clarity and comfort scores specific to OHMD usage.
    • Development of data-driven color guidelines that significantly broaden design options.

    Conclusions:

    • The proposed color guidelines enhance creative freedom and functional effectiveness in OHMDs.
    • These guidelines provide a valuable resource for designers, improving augmented reality interface aesthetics and usability.
    • The research addresses a critical gap in color management for mixed reality applications.
