Abstract: A touch sensor can be used with a finger and/or a pen configured to provide a touch input to the touch sensor. Some implementations involve touch capacitive touch sensing, although many implementations are also applicable to other touch and pen technologies, such as resistive, surface acoustic wave, bending wave, touch force, electromagnetic (E-M). Discrimination between intentional touches and unintentional touches on the touch surface can be performed using first criteria. For each touch identified as an intentional touch, discrimination between a finger touch and a pen touch can be performed using second criteria.
