Optical see-through Augmented Reality (OST-AR) is a developing technology that creates a mix of virtual and real using an optical combiner that blends images and graphics with the real-world environment. Because of its physical transparency, this novel display technology suffers from background bleed-through, which distorts color and contrast. However, displayed virtual content is usually easily understandable, thanks to perceptual scission, or the cognitive separation of foreground and background layers. Color appearance in OST-AR is strongly influenced by scission, which is influenced by transparency, depth, and parallax. This presentation will overview psychophysical research that has addressed perceived characteristics of color, material, and images in OST-AR. Results help both understand the visual mechanisms and improve tomorrow’s AR systems, which promise new human-computer interfaces in domains including education, medicine, and entertainment.
