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.

Abstract: Implementations of the technology described herein provide a method for detecting gesture commands using an ultrasonic pen system. The system has a pen and a user device. Detection of gesture commands is based on two-dimensional gestures relative to the screen of a user device, three-dimensional gestures relative to the screen of the user device, roll/rotation around a longitudinal axis of the pen body, and micro-twisting around the longitudinal axis of the pen body. The user device receives the gestures and translates them into commands such as UNDO and BACK.
