1. An apparatus comprising:
- capacitive sensors located in a viewable area of the apparatus, where the capacitive sensors are arrange in a first layer and a second layer, where the first layer is located on top of the second layer, where the capacitive sensors in the first layer are arranged in a substantially ring-shaped pattern, where the capacitive sensors in the first layer comprise a plurality of pairs of the capacitive sensors, where both capacitive sensors of each pair are aligned with other ones of the pairs in a common column or row, and where both capacitive sensors of each pair has an end which is outside the viewable area such that no leads from the capacitive sensors of each pair are in the viewable area; and
a cover window on top of the first layer, where the cover window does not comprise electrically conductive material.

11. An apparatus comprising:
-
a first layer comprising first capacitive sensors located in a viewable area of the apparatus, where the capacitive sensors in the first layer comprise a plurality of pairs of the capacitive sensors, where both capacitive sensors of each air are aligned with other ones of the pairs in a common column or common row, and where both capacitive sensors of each pair has an end which is outside the viewable area such that no leads from the capacitive sensors of each pair are in the viewable area; and a second layer comprising second capacitive sensors located in the viewable area of the apparatus, where the first layer is located on top of the second layer, where the first capacitive sensors are arranged in a substantially ring-shaped pattern, and where the second capacitive sensors are arranged in a pattern sized to fit under the first layer within an inside perimeter of the substantially ring-shaped pattern of the first capacitive sensors. - View Dependent Claims (12, 13, 14, 15, 16)

17. A method comprising:
-
providing a first layer comprising first capacitive sensors, located in a viewable area of an apparatus, arranged in a substantially ring-shaped pattern and first electrical conductors forming leads extending from the first capacitive sensors towards outer edges of the first layer, where the capacitive sensors in the first layer comprise a plurality of pairs of the capacitive sensors, where both capacitive sensors of each pair are aligned with other ones of the pairs in a common column or row, and where both capacitive sensors of each pair has an end which is outside the viewable area such that the leads from the capacitive sensors of each pair are not in the viewable area; providing a second layer comprising second capacitive sensors and second electrical conductors extending from the second capacitive sensors towards outer edges of the second layer, where the second capacitive sensors are arranged in a pattern having a substantially same size as an inner perimeter of the substantially ring-shaped pattern; and locating the first layer on top of the second layer, where the second electrical conductors are located at least partially under the first capacitive sensors. - View Dependent Claims (18, 19)
