System and method for dynamically disabling haptic feedback with recognition of pen on touch sensitive area of an information handling system
An information handling system includes a touch sensitive area, which in turn includes an array of pressure sensors and a haptics controller. The array of pressure sensors includes a first pressure sensor. When activated, the first pressure sensor provides an XY location based on a location of the first pressure sensor in the array of pressure sensors. The haptics controller receives an XY location from the first pressure sensor, and a location of a pen device from a pen digitizer circuit. The haptics controller calculates whether the XY location and the location of the pen device are substantially the same location. In response to the XY location and the location of the pen device being substantially the same location, the haptics controller disables haptic feedback within the touch sensitive area.
