....zoom Promising results have been reported on the potential of head pose as an auxiliary channel into the system. In orbital mode, for example, the user s head orientation is tracked and mapped so as to move the viewpoint of the user about the surface of a virtual sphere surrounding an object [Chung 1994]. Orbital mode is an excellent example of a technique not possible in the real world that gives the user power in the virtual environment. Chung found radiologists preferred it over six other methods of view direction control such as mouse, joystick, and walkaround, and hypothesized that that was ....

....selecting the flying mode. Users can choose between two flying modes: pointing mode and orbital mode. In pointing mode flying, a user flies in whatever direction he is pointing with his right hand. Orbital mode is a unique form of viewpoint specification first pioneered by Jim Chung at UNC (see [Chung 1994]) In orbital mode selected objects are constrained to stay in front of the user, regardless of which direction he is looking. The side of the object that is visible to the user depends on his current view direction: look up and he sees the object s bottom, look down and he sees its top (see ....
