Abstract
A method is disclosed for determining detecting a conductive object and determining the type of object and the type of contact that object has with a touch sensitive surface, the method comprising measuring capacitance on a plurality of mutual capacitance sensors, each mutual capacitance sensor corresponding to a unit cell in an array of unit cells. After mutual capacitance is measured a peak unit cell is identified based on the measured capacitances and a matrix sum of a plurality of unit cells surround the peak unit cell is calculated. The value of the peak unit cell and the matrix sum are then compared to a range and a contact type determined based on the comparison.
