Pressure-Sensitive Joy-Stick

      Disclosed is an enhancement to joystick devices making joystick
handles and joystick button/trigger surfaces sensitive to the degree
of pressure applied by the user.

      A joystick or other analog input device is often used in
conjunction with a computer, video game, or other electronic tool or
instrument.  The electronic/mechanical implementation of
pressure-sensitivity may differ depending on the technology used.

      For a joystick handle, both vertical (y-axis) and horizontal
(x- and z-axis) pressure components may be measured and applied
separately.  In fact, a moveable joystick could be replaced with a
stationary one that detects pressure components and translates them
into signals indicating joystick movement.

For joystick buttons/triggers, pressure-sensitivity may be
implemented in two flavors:
  Complete    A joystick button or handle is pressure-sensitive
               in all positions.
  Partial     A joystick button is pressure-sensitive only when
               completely depressed.  For example, it operates
               just like a normal button when not completely
               depressed and becomes pressure-sensitive once
               depression is complete.

      A joystick handle is not pressure-sensitive until it reaches
its movement limit (maximum angle), at which point it becomes
pressure-sensitive in the direc...
