Systems and methods for illuminating a track pad system

A track pad system comprising:

• a two-dimensional array of force sensors arranged to have a length and a width, the two-dimensional array of force sensors being disposed on a first surface of a circuit board;
• a touch interface plate disposed over the two-dimensional array of force sensors, the touch interface plate comprising a lower surface disposed facing the two-dimensional array of force sensors and an upper surface opposite the lower surface, wherein the touch interface plate passes touch forces incident on the upper surface through to at least two of the force sensors of the two-dimensional array of force sensors, and wherein the lower surface of the touch interface plate is spaced apart from the first surface of the circuit board;
• at least one light source disposed on the first surface of the circuit board and adjacent a lower surface of the touch interface plate such that at least a portion of the touch interface plate is illuminated;
• and
• a feedback generator connected to the circuit board and coupled to the lower surface of the touch interface plate, wherein the feedback generator generates at least one of a tactile or audible feedback that is amplified by the touch interface plate.
