Abstract
A touch-sensitive display device comprises a touch sensitive-display including display electrodes configured to detect proximity of input objects to the touch-sensitive display. A touch controller is configured to determine a two-dimensional position of a stylus touch input based on information from the plurality of display electrodes. An indication of a tilt angle and an azimuthal angle of the stylus is received. A touch restriction region is defined based at least on the two-dimensional position of the stylus touch input and the tilt and azimuthal angles of the stylus. Touch inputs within the touch restriction region are processed differently than touch inputs outside the touch restriction region.
