1. A method for operating a capacitance sensing device comprising:

  • detecting a capacitive profile of an object proximate to the capacitance sensing device, the capacitive profile comprising first capacitance portions and second capacitance portions, wherein at least one of the second capacitance portions is between two of the first capacitance portions, a capacitance value of the first capacitance portions being greater than a capacitance value of the second capacitance portions; and

    determining data associated with the object based on the capacitive profile of the object.
