Abstract
An aircraft includes a cursor control device having a defined return path for the touch sensor so that the impedance in the return path is known. The defined return path is embodied in a conductive feature in the cursor control device palm contact area to ground the user and improve the system's signal to noise ratio. The defined return path normalizes signal variability due to environmental factors and user specific factors such as finger size, skin moisture, contaminants, etc.
