1. A touch-sensitive apparatus, the apparatus comprising:
a touch-sensitive element comprising an array of electrodes having a first electrode and a second electrode, the second electrode spatially intersecting the first electrode at an intersection point; and
measurement circuitry configured to:
measure the mutual capacitance at the intersection point of the first and second electrodes;
measure the self-capacitance of the first electrode, and
measure the self-capacitance of the second electrode; and
processing circuitry configured to:
determine the presence of a touch on the touch-sensitive element on the basis of a comparison of the measured mutual capacitance at the intersection point to a first threshold and on the basis of a combination of the measured self-capacitance of the first electrode and the measured self-capacitance of the second electrode being greater than or equal to a second threshold.
