Zusammenfassung:A method and apparatus for a multi-modal capacitive touchscreen interface. The multi-modal facet pertains to the mutability of the user's input modes and environments. The interface includes a display operable to display information on a device, and a touch sensitive layer disposed on the display, where the touch sensitive layer provided a plurality of capacitive nodes distributed on the display. A touch controller is coupled to the layer and is operable to detect a change of capacitance at a particular node, wherein if the touch controller detects a capacitance level at the particular node that is outside of a defined range, the touch controller automatically adjusts a sensitivity of the touch sensitive layer such that subsequent touches of the interface should fall within the defined range.
