Improving the visibility of a three-dimensional image by Pepper's Ghost using a rotating transparent boards

Abstract

In this research, we present a three-dimensional image of a Pepper's Ghost, and simultaneously observed from multiple angles by rotating it. Pepper's Ghost is a method to make an image appear to be floating in the air by combining an image reflected on a transparent board with a background. The system consists of a monitor lying on its side, a transparent board with a viewing angle control film on it, and a motor. Evaluation experiments have shown that there is a trade-off between the clarity of the 3D image and eye strain depending on the rotation speed. The purpose of this study is to investigate whether the size of the transparent plate improves or increases visibility. Visibility in this study is defined as the resolution and frame rate of the stereoscopic image and the vertical viewing angle.
