Abstract
A base noise level of a touchscreen interface for a computing device is actively and adaptively calibrated. Antenna traces forming a digitizer of the touchscreen interface are allocated into antenna regions. Antenna regions with high energy signal levels and antenna regions with low energy signal levels are identified. Signal level information from high energy antenna regions is discarded. A noise level, caused by electrical components of the computing device, is determined within signals generated in the antenna traces based at least in part upon the low energy antenna regions. The digitizer is calibrated by reducing energy levels of signals carried by the antenna traces in all antenna regions by the noise level.
