Vehicle Display and Control System Utilizing a Pointing Device

      Disclosed is a method of combining a display device and a
pointing device to centralize vehicle information and control for the
purpose of maximizing the ability of a driver to view vehicle
instruments, operate vehicle controls, and view the road.

      A display device, such as a CRT, is placed in the normal
vehicle instrumentation location.  A pointing device, such as a
trackball and associated switches are located on the steering wheel.
Both are connected to a computer in the vehicle.  A typical example
is shown in the figure.

      The trackball device operated in a manner similar to that of a
computer "mouse".  That is, rotation of the trackball moves a
pointer, visible on the display device, to select an operation while
pressing one of the associated switches activates the selected
operation.

      The primary display presentation would contain normal
instrumentation information, such as speed, miles traveled, gasoline
level, etc.  This display presentation would also contain icons for
secondary display presentations, such as climate control, cruise
control, radio, etc.  The trackball and associated switches would
allow selection of secondary display presentations as well as
functions on those displays.  An example would be selection of the
climate control display presentation and activation of the fan
control.  This method minimizes the need for a driver to remove a
hand fr...
