遠隔作業インタフェースとしての背面投射型球面ディスプレイの開発

抄録

Recently, many new potential uses of telerobotics and virtual reality have been explored in medical field. In order that a human operator can easily and intuitively execute the given micro operation, the development of suitable visual and haptic interfaces and the accurate registration of them are significantly important. However, these technical subjects are not easy to solve and have not been seriously considered. HMD is unsuitable for the surgical application because of its weight, restriction and narrow range of view. Recently, an immersive projection technology is drawing the attention for the virtual reality. In this paper, a compact and accessible spherical display with a stereo viewing system is discussed as an interface of teleoperation. The operator looks into the spherical display like a fortuneteller viewing a crystal ball. This environment is different from the immersive one surrounded by screens. The validity of developed system is confirmed by the experiment.
