“…Indeed, VR is one area in which psychophysical methods indeed help with the development of novel displays (Scarfe & Glennerster, 2019). Similarly, AR allows for the mixing of onthefly parametric stimulus control with concurrent viewing of the natural world (Hassani & Murdoch, 2019;Murdoch, 2020).…”

“…Hassani et al explored the color appearance in a color-matching experiment with combinations of mixed foreground and background colors and tested the applicability of the CAM16 color appearance model in an AR environment. From their results, the prediction of CAM16 was not ideal, and they suggested it should be improved by modifying it with the addition of chromatic simultaneous contrast to produce a better result [22]. Chien and Sun investigate the preferred tone curves and background lighting geometries of a see-through head-mounted LCD with five psychophysical experiments.…”

Up until now, head-up displays (HUDs) have been installed in front of the driver’s seat to provide drivers with auxiliary information. It may be used in various surroundings, ranging from very dark to very bright environments, such as daylight. A suitable text-background lightness combination can improve the driver’s visual clarity and efficiency when identifying displayed information to raise driving safety. Although many kinds of HUDs are designed to improve visual clarity by adjusting brightness, few studies have investigated the influence of the text-background lightness combination of a HUD on visibility, especially as the lighting level of the driving condition changes dramatically. In the study, 60 observers, comprising 20 young, 20 middle-aged, and 20 older participants, evaluated the visual clarity of 20 text-background lightness combinations on a HUD using paired comparison methods under dark and daylight surroundings (i.e., 300, 1500, and 9000 lx conditions). As a result, the combination of white text on a black background and black text on a white background presented the most significant preference and the best visual clarity under dark and daylight surroundings, respectively, improving visual safety when driving.

“…When images are presented through optical see-through (OST) devices, such as transparent or AR glasses, in ambient conditions, both the light from the images on the OST devices and the light from the real-world background enter the viewers' eyes. Most studies on the brightness perception of Augmented Reality (AR) images assume that only AR object images are superimposed on the real-world background (Figure 1-(a)) [1][2][3][4]. These studies conduct experiments to investigate the contrast effect between the AR object in the AR images and the real-world background.…”

The Effect of an Ambient Contrast of AR (Augmented Reality) Images on Brightness Perception

In an ideal AR device, only the AR object image should appear in the real environment. However, certain AR devices, such as those using a half mirror, also present the AR background surrounding the AR object due to the transmittance of the half mirror. This might be perceived as a two-dimensional display image overlapping onto the real environment. In this scenario, the perception of brightness might differ from cases where only an AR object is superimposed on the real-world background. To explore the brightness perception of AR images presented by AR glasses with half mirrors, we conducted two psychophysics experiments. In Experiment 1, using a single pair of AR glasses, we observed the brightness perception of AR images under various correlated color temperatures (CCTs) for exterior lighting. Participants perceived the AR image to be brighter than the reference image with the same luminance. The CCT of the exterior lighting had no significant effect. In Experiment 2, we investigated the effect of the AR background on the brightness perception of AR images using two pairs of AR glasses with different transmittances (35% vs. 70%). Participants perceived AR images to be brighter than the reference when using glasses with lower transmittance. These results suggest the interaction effect between the image contrast and the ambient contrast on brightness perception in AR glasses with half mirrors.
