Abstract
A position sensing system includes a plurality of two-axis anisotropic magneto-resistive (AMR) sensors to determine the position of a user interface. A magnetic member is coupled to the user interface, which is movable to a position along a random path. The plurality of two-axis AMR sensors is arranged in a two-dimensional sensor array that is spaced apart from the magnetic member. A signal processor circuit is operable to sense the electrical resistance values of each two-axis AMR sensor, to determine the position of the user interface from the resistance values, and to supply position feedback data representative of the determined position.
