Immersive Multi-Projector Display on Hybrid Screens with Human-Scale Haptic Interface

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. In the view of human-scale interactive system for virtual environment (VE), the existing immersive systems are not enough to use the potential of a human sense further extent. The displays require more complicated structure for flexible extension, and are more restrictive to user’s movement. Therefore we propose a novel multiprojector display for immersive VE with haptic interface for more flexible and dynamic interaction. The display part of our system named “D-vision” has a hybrid curved screen which consist of compound prototype with flat and curve screen. This renders images seamlessly in real time, and generates high-quality stereovision by PC cluster and two-pass technology. Furthermore a human-scale string-based haptic device will integrate with the D-vision for more interactive and immersive VE. In this paper, we show an overview of the D-vision and technologies used for the human-scale haptic interface. key words: immersive projection technology, human-scale virtual environment, multi-modal interaction, force feedback
