Abstract
An electronic device improves touch accuracy and prevents false or missed touches on a capacitive touch display by monitoring contextual events or environments unrelated to user input. When a capacitance change occurs, the device dynamically evaluates whether it may have been caused by the contextual events or environments. The device intelligently adjusts one or more parameters to account for the change in capacitance caused by the contextual events or environments to thereby prevent detection of the capacitance event as a false touch and/or prevent a missed true and legitimate user input.
