1. A method comprising:
- receiving, from a touch sensor of a device, one or more signals corresponding to touch or proximity inputs within a touch-sensitive area of the touch sensor, the touch sensor comprising one or more nodes;
applying an offset to one or more of the signals, the offset corresponding to a variation in a distance between a touch panel and a ground plane or display of the device; and
determining whether a touch input to the touch sensor has occurred based at least in part on the signals and the offset as applied.

Abstract
In one embodiment, a method includes receiving, from a touch sensor of a device, one or more signals corresponding to touch or proximity inputs within a touch-sensitive area of the touch sensor. The touch sensor comprising one or more nodes. The method also includes applying an offset to one or more of the signals. The offset corresponding to a variation in a distance between a touch panel and a ground plane or display of the device. The method also includes determining whether a touch input to the touch sensor has occurred based at least in part on the signals and the offset as applied.
