1. An apparatus for sensing a foot of a user comprising:
a range imaging camera;
a computer; and two or more individual sensing tiles formed of layers in communication with the computer that form a sensor surface, using protrusions under the surface and bridging plates that extend between tiles and contact adjacent tiles with no protrusions on corners of the bridging plates where the protrusions transmit forces only to specific locations, that detects force applied to the surface by the foot on the surface, and provides a signal corresponding to the force to the computer which produces from the signal a time varying continuous image of force applied to the surface, where the surface is contiguous, and detected force can be sensed in a manner that is geometrically continuous and seamless on a surface, the computer using the camera to reject unwanted input from the image of force, the protrusions integrated into one layer of the layers and the protrusions and one layer are a single mechanical component, each sensing tile supporting a weight of the user on the user's foot, the protrusions are in contact with a plurality of intersections of a grid of wires of another layer of the layers, and the protrusions focus an imparted force of the foot directly onto the intersections.
