- A Mixed-Reality Showcase for Multiple Users from Unconstrained Viewing Angles

Description:
An ideal showcase should allow its viewers not only see the display object clearly, but also obtain sufficient information of the object by static texts or dynamic images. In this work, we proposed a novel mixed-reality showcase that is able to superimpose any virtual images and the real object and hence is able to offer the users lots of information of the real object through virtual images. In addition, we overcome the limitation of the existing solution that our proposed showcase is able to display different virtual images for multiple users with unconstrained viewing angles. We believe that the proposed mixed-reality showcase will have a significant promise for commercial product advertisement and museum exhibitions.
An ideal showcase should allow its viewers not only see the display object clearly, but also obtain sufficient information of the object by static texts or dynamic images. This extra information will enhance the impression the display object makes on viewers. For a 360-degree showcase, it is a challenging problem to provide proper virtual images for users at different viewing locations. In literature, [Kim et al.] proposed a pyramid-shaped showcase in which the display object is placed and half-silvered mirrors were employed to reflect the virtual image for four viewing directions (left, right, front, and rear). Though the user can observe both the virtual image and real object well in each of the aforementioned viewing directions, the geometry inconsistency would occur at the middle of the consecutive two viewing directions. Commercial product, Lite-Fast MAGIC [Kinoton], also developed a 360-degree mixed-reality transparent LED display, however it will result in ghost artifact when showing virtual information for different viewing directions due to its transparent material.
