1. A capacitive touch sensing system, comprising:
- a touch surface; and
sets of electrically connected and substantially parallel electrodes arranged in relation to the touch surface, each set of electrodes including a primary electrode and at least two sub-electrodes disposed on either side of the primary electrode and having a smaller surface area than the primary electrode, wherein the sub-electrodes of the electrode sets are interleaved.

Abstract
A capacitive touch sensing system includes a touch surface and sets of substantially parallel electrodes arranged in relation to the touch surface. Each electrode set includes a primary electrode electrically connected to at least two sub-electrodes. The primary electrode is capable of producing greater capacitive coupling to a touch in proximity with the touch surface in relation to capacitive coupling of the at least two sub-electrodes. The sub-electrodes of the electrode sets are arranged in an interleaved pattern configured to increase an effective area of capacitive coupling associated with each electrode set.
