Abstract
In this paper, we name the action of browsing 3D virtual space in human scale virtual environment using scrolling technique "space browsing", and propose space browsing interface system based on estimating user's head posture. Head posture estimation is carried out in real-time by processing image of an oval marker put on user's head. Because the oval marker is attached on a cap, a user can put on the marker easily and naturally by just wearing the cap. Our method gives natural feeling to a user because the direction of scrolling has good consistency to user's direction of attention. We made experiment in which space browsing interfaces based on mouse and our method are compared, and the result shows that our method gives shorter task completion time.
