Immersive multi-projector display on hybrid screens with human-scale haptic and locomotion interfaces

Many immersive displays developed in previous researches are strongly influenced by the design concept of the CAVE which is the origin of the immersive displays. We propose a novel multiprojector display for immersive virtual environments. Our system named "D-vision'' has a hybrid curved screen which consist of differently shaped surface elements that are partial surfaces of such objects as planes, spheres, cylinders and tori. 24 PCs and projectors generate high-quality stereoscopic images. Our rendering algorithm using our original image processing hardware and commodity 3D graphics hardware realizes seamless and nondistorted projection on the hybrid screen. The D-vision also has a human-scale haptic and locomotion interface by which the users of the D-vision can walk with their own foot and interact with virtual objects through their own hands. We show an overview of the D-vision and technologies used for the human-scale haptic- and locomotion interfaces.
