Ubiquitous throughout the history of photography, white borders on photo prints and vintage Polaroids remain useful as new technologies including augmented reality emerge for general use. In contemporary optical see-through augmented reality (OST-AR) displays, physical transparency limits the visibility of dark stimuli. However, recent research shows that simple image manipulations, white borders and outer glows, have a strong visual effect, making dark objects appear darker and more opaque. In this work, the practical value of known, inter-related effects including lightness induction, glare illusion, Cornsweet illusion, and simultaneous contrast are explored. The results show promising improvements to visibility and visual quality in future OST-AR interfaces.
