1. A touch system, comprising:
- a touch panel, comprising;
a first layer of one or more first electrodes electrically connected in an arrangement that produces a regional ambiguity in a touch location determined using the first electrodes with respect to a first axis; and
a second layer of one or more second electrodes configured to resolve the regional ambiguity of the touch location with respect to the first axis.

Abstract
A touch panel includes first and second layers of electrodes. The first layer of electrodes is electrically connected in an arrangement that produces a regional ambiguity in a touch location determined using the first electrodes with respect to a first axis. The second layer of electrodes is configured to resolve the regional ambiguity of the touch location with respect to the first axis. Conversely, the second layer of electrodes may also be connected in an arrangement that creates regional ambiguity in touch location determination of the second layer, and the first layer of electrodes may be configured to resolve that regional ambiguity.
