Abstract
An apparatus that has a touchscreen, is configured to determine a response to a contact by a hand with a region of the touchscreen, and includes a first means for determining a location of a graphical projection of a digital pen onto the touchscreen, a second means for determining, via an ultrasonic wave, a first angle between a first line along an edge of the touchscreen and a second line along the graphical projection, a third means for determining a distance between the touchscreen and the digital pen, and a fourth means for determining, from the distance, the response to the contact by the hand with the region defined by the location and the first angle.
