2.3 Joystick

Joystick motion is another form of hinge motion which will occur about the origin as typically observed in human-machine interfaces such as video game controllers, automotive turn indicators, and other various industrial machine controls. This type of motion is described in Designing Joysticks with Hall-effect Sensors and Measuring 3D Motion with Absolute Position Encoders

Figure 2-9 Joystick Motion

To Simulate joystick configurations select "Joystick" from the top menu as shown in #GUID-D0DD07DF-971C-4E5D-BFB1-113A6FE112BB.

Figure 2-10 Joystick Function Selection

The resulting prompt will appear as shown in #GUID-407A104F-6E00-432D-A3DE-10AFC2960287

Figure 2-11 Joystick Function User Inputs

Magnet travel for this type of motion pivots about the origin by a distance described by "Tilt Angle" and in a direction "XY Angle". The normal expectation is that the magnet is placed at a location in the negative Z-direction. This distance is the fulcrum distance for the magnet. The sensor is also typically placed in the negative Z-direction below the magnet.

#GUID-4A28A379-1422-4717-BA0B-6C7445F5B225 illustrates that as the magnet tilts, the range to the sensor increases accordingly in the required direction.
