ABSTRACT
A novel method for an all-around display system that shows three-dimensional stereo images without the need for special goggles has been developed. This system simply needs a directional-reflection screen, mirrors, and a standard projector. The basic concept behind this system is to make use of the phenomenon called "afterimage" that occurs when screen is spinning. The key to this approach is to make a directional reflection screen with a limited viewing angle and project images onto it. The projected image is made up of 24 images of an object, taken from 24 different angles. By reconstructing this image, a three-dimensional object can be displayed on the screen. The display system can present images of computer-graphics and photographs, full-length movies, and so on.Our aim is to make a system for not only displaying images but also for interacting with them. Several display examples demonstrated that the system will be useful in applications such as guide displays in public places and facilities.

Transpost: A Novel Approach to the Display and Transmission of 360 Degrees-Viewable 3D Solid Images
Three-dimensional displays are drawing attention as next-generation devices. Some techniques which can reproduce three-dimensional images prepared in advance have already been developed. However, technology for the transmission of 3D moving pictures in ...
Vision-enhanced Immersive Interaction and Remote Collaboration with Large Touch Displays
MM '15: Proceedings of the 23rd ACM international conference on MultimediaLarge displays are becoming commodity, and more and more, they are touch-enabled. In this keynote, we describe a system called ViiBoard (Vision-enhanced Immersive Interaction with touch Board) that enables natural interaction and immersive remote ...
Image-based 3D telecopier: a system for sharing a 3D object by multiple groups of people at remote locations
VRST '10: Proceedings of the 17th ACM Symposium on Virtual Reality Software and TechnologyWe propose a system that allows multiple groups of users at remote locations to naturally share a 3D image of real objects. All users can interactively observe a 3D stereoscopic image without distortion from their own viewpoints. The system basically ...
