3D-Mirrorcle: Enhancing Augmented Reality Mirror Systems through Depth Alignment

Core Concepts
3D-Mirrorcle is an innovative augmented reality (AR) mirror system that effectively addresses the issue of depth disparity between the 3D mirror reflection and the 2D screen display through a hardware-software co-design.
The paper introduces 3D-Mirrorcle, an innovative augmented reality (AR) mirror system that addresses the challenge of depth misalignment between the 3D mirror reflection and the 2D screen display. The key components of the 3D-Mirrorcle system include: Hardware Design: The system consists of a screen, a lenticular grating, and a half-mirror, tightly attached without any gaps. It also includes a depth camera to locate the user's eyes and a color camera to capture images. Mirror Reflection Alignment Algorithm: This algorithm adjusts the image to an appropriate position on the screen by mapping each point on the mirror surface to its corresponding location on the screen. Lenticular Grating Segmentation Algorithm: This algorithm ensures that the left and right eyes see the intended images on the screen by leveraging the properties of a lenticular grating to create distinct views for each eye. The authors conducted user experiments with 36 participants to evaluate the performance of 3D-Mirrorcle compared to a 2D smart mirror baseline. The results showed significant improvements in accuracy (24.72% increase), immersion (31.4% increase), and user satisfaction (44.4% increase) with the 3D-Mirrorcle system. The paper also discusses the potential applications of 3D-Mirrorcle, including makeup guidance, facial massage, jewelry try-on, hair cutting, fitness instruction, interactive gaming, embodied education, and exhibition displays.
The accuracy of the 3D-Mirrorcle system was 80.69%, which was 24.72% higher than the 2D smart mirror baseline of 55.97%. The task completion time for the 3D-Mirrorcle system was 6.19 seconds, which was not significantly different from the 2D smart mirror baseline of 5.58 seconds.
