Abstract
A method includes detecting presence of a handheld device in proximity of a touch enabled device and negotiating communication capabilities between the handheld device and a digitizer system of the touch enabled device. At least one of the handheld device and the digitizer system is configured to match a defined communication capability of the other of the at least one of the handheld device and digitizer system. Input from the handheld device is tracked via an electrostatic communication channel between the handheld device and the digitizer system based on the defined communication configuration.
