Optical-reflection type 3D augmented reality mirrors

Abstract

Augmented Reality (AR) mirrors can show virtual objects overlaid onto the physical world reflected in the mirror. Optical-reflection type AR mirror displays use half-silvered mirrors attached in front of a digital display. However, prior work suffered from visual depth mismatch between the optical reflection of the 3D physical space and 2D images displayed on the surface of the mirror. In this research, we use 3D visualisation to overcome this problem and improve the user experience by providing better depth perception for watching and interacting with the content displayed on an AR mirror. As a proof of concept, we developed two prototype optical-reflection type 3D AR mirror displays, one using glassesfree multi-view 3D display and another using a head tracked 3D stereoscopic display that supports hand gesture interaction.
