When used with a discrete output, like the D-Pad buttons, the joystick's position is divided up into a series of zones,
such as North, South, East and West, which triggers a signal when the joystick is moved into a zone.
The discrete zones are further divided into the Ordinal directions, North-East, South-East, etc as well as into Inner
ring and Outer ring zones, in a manner similar to the dual pressure thresholds for the Sip/Puff sensors. When
moving through the inner ring, a tone is produced to indicate the joystick is within the inner ring region and a click
is produced when either the time delay expires, or the joystick moves into the outer ring and an outer ring signal
is triggered.
The Joystick Discrete Zones diagram shows the active areas to which the joystick can be positioned to trigger a
signal. The areas of deeper color saturation, around the Cardinal and Ordinal directions, show where the joystick
must be to be detected. The lighter mixed color areas between the eight directions show hysteresis areas where
the previous signal will remain active until the joystick enters the next detection zone. For instance, starting at
North, the joystick can be moved from the Green area, into the Blue-Green-Gray area towards either NE or NW and
still maintain the North signal. It can move back into the Green area and no interruption of the North signal will have
occurred. However, once the joystick crosses into the Blue area around NE or NW, that new signal becomes active
and will remain active as long as the joystick remains in the Blue area or the adjacent Blue-Green or Magenta areas.
The inner and outer rings operate like the Soft and Hard Sip/Puff pressures: After entering the Inner ring, the user
must hold the joystick in the area between the Hysteresis ring and the Outer ring until a timer expires and triggers
the signal. A tone that varies with the position will sound until the timer expires. Once the Inner ring timer has
expired and the inner ring signal is activated, the joystick has to return to the center position before moving to trigger
an Outer ring signal. Once triggered, either the inner or outer ring signals will stay active as long as the joystick
stays outside the Hysteresis ring. The joystick deflection between the Outer ring and the maximum deflection is
scaled into the pressure applied to the corresponding PS3 button, if so mapped.
