Large-Scale Projection-Based Immersive Display: The Design and Implementation of LargeSpace

In this paper, we introduce LargeSpace, the world's largest immersive display, and discuss the principles of its design. To clarify the design of large-scale projection-based immersive displays, we address the optimum screen shape, projection approach, and arrangement of projectors and tracking cameras. In addition, a novel distortion correction method for panoramic stereo rendering is described. The method can be applied to any projection-based immersive display with any screen shape, and can generate real-time panoramic-stereoscopic views from the viewpoints of tracked participants. To validate the design principles and the rendering algorithm, we implement the LargeSpace and confirm that the method can generate the correct perspective from any position inside the screen viewing area. We implement several applications and show that large-scale immersive displays can be used in the fields of art and experimental psychology.
