Navigational Compass for Traversing a Three-Dimensional World

      The invention discloses a control for navigating in a
three-dimensional virtual world.  The device is represented as a
compass and allows for steering, viewing, and acceleration control.

      The user navigates through the three-dimensional world by
interacting with a graphically represented on-line compass.  By using
a mouse, the user can drag the compass through the virtual world.
The world will move by their view, presenting the appropriate views
that represent the chosen pathway.  Virtually drawing a line through
the landscape as it changes and moves, the user can traverse the
world. The  compass is used like the viewfinder on a submarine, the
steering wheel  of a car, and the brakes and accelerator pedals all
at the same time.  The user can indicate how fast they want to move
and then once moving, in which direction.  They can stop and use only
the viewfinding  capabilities to look around from a stopped position.

      Presented to the user is a small wheel, to be used alone or
attachable to any apparatus or robot-like device existing in the
environment.  For instance, for virtual shopping, a shopping cart
device could be used to give the user a location in which to 'place'
their purchases.  The compass could be incorporated into the shopping
cart metaphor.  Or, as another example, if there is a front panel
type of 'dashboard' of controls, the control panel could be
incorporated there.  Or, it can be used alo...
