Abstract

A method includes sampling output from sensor having electrode junctions integrated on a device including a display, detecting capacitance between the device ground and a user (CBD) based on the output sampled and a pre-defined model, and defining one of two grounding states of the device based on the capacitance detected. Output is processed based on the grounding state defined and touch coordinates are determined based on the output processed. The touch coordinates are reported to a controller of the display.
