1. A method for determining a location of contact on a touch sensitive device, the method comprising:
measuring contact capacitances of a plurality of electrodes in a vicinity of a contact on the touch sensitive device, wherein the touch sensitive device comprises a first electrode layer orthogonal to a second electrode layer;
determining a mechanical deflection capacitance of a remote electrode positioned a distance away from an electrode of the plurality of electrodes, wherein the remote electrode and the plurality of electrodes correspond to the first electrode layer;
determining a plurality of mechanical deflection capacitances of the plurality of electrodes based at least on the mechanical deflection capacitance;
adjusting the contact capacitances based at least on the plurality of mechanical deflection capacitances; and
determining the location of the contact based on the adjustment.
