1. An input device configured to control a user interface indicator of an electronic device, the input device comprising:
- a substrate having a plurality of sensor electrodes disposed thereon; and
an elastomeric material mechanically coupled to the substrate and overlapping the plurality of sensor electrodes, the elastomeric material having an inner portion disposed such that an area of contact between the inner portion and at least some of the plurality of sensor electrodes changes in response to at least one of a lateral force or a vertical force applied to the elastomeric material.

Abstract
In an example, an input device includes a substrate and an elastomeric material. The substrate includes a plurality of sensor electrodes disposed thereon. The elastomeric material is mechanically coupled to the substrate and overlaps the plurality of sensor electrodes. The elastomeric material includes an inner portion disposed such that an area of contact between the inner portion and at least some of the plurality of sensor electrodes changes in response to at least one of a lateral force or a vertical force applied to the elastomeric material.
