摘要：An embodiment of the invention provides a method and apparatus for
determining what type of interaction is made with a capacitive touch screen. A capacitancesensor with the largest sensed capacitance in a group of capacitance sensors isdetermined. Next, a parametric surface is determined from the value of the largest
sensed capacitance and the values of the sensed capacitances in the group of capacitancesensors. From the parametric surface, an interpolated peak capacitance, a curvature K atthe interpolated peak and an orientation θ at the interpolated peak are determined.Based on the interpolated peak capacitance, the curvature K and the orientation θ, thetype of interaction made with the capacitive-touch screen is identified.
