Patent ID: 8098154

Claim:
A simulation method processed by a processor, comprising: establishing a substantially planar conductive grid comprising a plurality of conductive elements, wherein the plurality of conductive elements comprises a first plurality of conductive elements that extend linearly, spaced apart from one another, across the conductive grid, generally in a first direction, and a second plurality of conductive elements that extend linearly, spaced apart from one another, across the conductive grid, generally in a second direction; coupling electrical energy to at least portions of the conductive grid and thereby providing wireless electrical energy in a vicinity of the conductive grid; receiving by the conductive grid a wireless location indicating indicium relative to the conductive grid from a transmitter unit in the vicinity of the conductive grid; determining a location on the conductive grid where the wireless location indicating indicium was received by the conductive grid; and displaying the location of the wireless location indicium relative to the conductive grid.
