Abstract: Systems and methods for capacitive field tuning for detecting touches on objects are disclosed. For example, an identity of an object placed on a touch-sensitive surface is determined and signal impedance characteristics associated with the object are also determined. The signal impedance characteristics may be utilized to determine tuning settings to apply to capacitive sensors such that the capacitive field of the device extends from the touch-sensitive surface to a touch surface of the object.
