Abstract
A hall effect system having a housing, an input element coupled to the housing, and a magnetic element coupled to the input element and configured to have a detectable magnetic flux. A sensing element is adjacent to the magnetic element. The sensing element is configured to sense the magnetic flux. A processing element is coupled to the sensing element and is configured to determine a position of the magnetic element relative to the sensing element by determining changes in and/or the orientation of the magnetic flux upon movement of the interface element by a user.
