Abstract
A method includes detecting a signal emitted by a stylus with a digitizer sensor, determining coordinates of the stylus, identifying a hover operational mode based on input received by the stylus, detecting a capacitive effect of a tip of the stylus on the digitizer sensor and reporting a touch operational mode of the stylus based on the capacitive effect detected. The capacitive effect of the tip of the stylus on the digitizer sensor is based on mutual capacitive detection and is performed in a defined area around the coordinates determined.
