A New Navigation Method for 3D Virtual Environment Exploration


Navigation in virtual environments is a complex task which imposes a high cognitive load on the user. It consists on maintaining knowledge of current position and orientation of the user while he moves through the space. In this paper, we present a novel approach for navigation in 3D virtual environments. The method is based on the principle of skiing, and the idea is to provide to the user a total control of his navigation speed and rotation using his two hands. This technique enables user-steered exploration by determining the direction and the speed of motion using the knowledge of the positions of the user hands. A module of speed control is included to the technique to easily control the speed using the angle between the hands. The direction of motion is given by the orthogonal axis of the segment joining the two hands. A user study will show the efficiency of the method in performing exploration tasks in complex 3D large-scale environments. Furthermore, we proposed an experimental protocol to prove that this technique presents a high level of navigation guidance and control, achieving significantly better performance in comparison to simple navigation techniques.
