Stereoscopic imaging beyond the boundaries of displays and projectors through perceptual completion based on transparency illusion

This study proposes a novel method to resolve discontinuities—specifically differences in luminance, color, and latency—between heterogeneous devices in a hybrid display environment combining a display and a projector. Conventionally, technical corrections for these discrepancies have been associated with issues such as image quality degradation and increased display latency. Therefore, instead of pursuing strict physical consistency, this study adopts an approach that utilizes human perceptual characteristics to achieve connection without physical continuity. Specifically, by intentionally creating a physical gap between devices and inducing the brain’s completion mechanism via the transparency illusion, discontinuities are perceptually masked. Evaluation results demonstrated that for organic shapes, the proposed method significantly improved continuity and naturalness compared to the conventional method, with notable improvements observed in motion smoothness and luminance uniformity. This method serves as a foundational technology for seamlessly connecting heterogeneous devices and realizing immersive expressions in future configurations, such as L-shaped stereoscopic setups.
