Methods for interacting with an electronic device by using a stylus comprising body having conductive portion and systems utilizing the same

A system includes a stylus including a body having an elongated portion, a tapered portion coupled to the elongated portion, and a conductive layer disposed on the elongated portion, an electronic device, a touch controller and a processing unit. The electronic device comprises a touch sensor generating a sensing signal when the touch sensor senses the conductive layer. The touch controller is coupled to the touch sensor, receives the sensing signal and generates a first signal based on the received sensing signal. The processing unit is coupled to the touch controller, receives the first signal and triggers a function of the electronic device based on the first signal.
