Abstract:
A touch input device configured to detect a touch input event and determine if the touch input event is caused by a floating object is provided. The touch input device includes one or more electrodes that scanned with a set of stimulation signals to first detect the presence of a touch event and then scanned with subsequent sets of stimulation signals in order to determine if the touch event is from a grounded object, a poorly grounded object, or a floating object.
