I'd like to hear your thoughts on the navigation techniques that might be employed. We are in the initial planning stage of software development for a project that involves navigating and interacting in an immersive environment. We want to collect data concerning physiological responses to the task of orienting oneself spatially in 3 dimensions, and then navigating from one location to another. We must choose the interaction devices and techniques that will be used. We can assume we have some sort of button device with 6 DOF tracking. Two experiments are envisioned. The first involves orientation and simple navigation in a virtual room where each wall is textured with a large checkerboard pattern. The room is rectangular and the walls are different colors. Subjects will be initialized at an arbitrary position and orientation. The task will be to navigate to a new position. The second involves orientation, navigation and interaction with objects in a model of the international space station. Interaction is simple, consisting of 'touching' one or more wall switches in the virtual environment. Training transfer is not an important issue, but we'd like to implement reasonable techniques. For example, we've all seen pictures of astronauts pushing off one wall and arresting motion on another. A wall touch technique based on collision detection comes to mind, but the control and feedback issues are complex. We've got several other ideas, but I'd like to hear your unbiased thoughts on the techniques that could be applied. Thanks 1.0E+06, Rob King Old Domin
