STYLUS FOR OPERATING A DIGITIZER SYSTEM

摘要

A handheld device includes a conductive tip configured to interact with a capacitive based digitizer sensor, an active transmission module, a reflective transmission module, a switch configured to connect the conductive tip to one of the active transmission module and the reflective transmission module and a controller configured to toggle position of the switch. The active transmission module configured to generate a first signal on the conductive tip independent from a drive signal transmitted on the digitizer sensor. The reflective transmission module is configured to generate a second signal on the conductive tip based on the drive signal transmitted on the digitizer sensor and picked by the conductive tip during interaction with the digitizer sensor.
