Abstract
An electronic appliance including a processor and a computer-readable medium, having instructions for execution by a processor is provided. The instructions causing the processor to perform methods to obtain an error map for locations in a touch sensor. The method including inputting a geometry for a touch sensor layout; inputting coordinates for centroids of sensing elements in the touch sensor layout; and inputting a touch geometry. The method includes the steps of selecting a plurality of test points on the touch sensor layout; generating, a calculated touch location for each of the plurality of test points; and an error map from the calculated touch locations and the test points. The method may include generating an error measure from the error map; displaying, the generated error map and the generated error measure; and adjusting the geometry for the touch sensor layout if the error measure is larger than a tolerance value.
