| Zusammenfassung: | A circuit, method, and system is disclosed for measuring capacitance of a plurality of electrodes, detecting a presence of a conductive object proximate to at least one of the plurality of electrodes near an edge of a touchscreen display based on the measured capacitance, assigning a value to at least one virtual sensor derived from the measured capacitance of the at least one of the plurality of electrodes near the edge of the touchscreen display and activating at least one control element associated with a location outside the display area based on the value of the at least one virtual sensor. |
