An active stylus includes an elongated body, an electrode provided at a tip end of the elongated body, an indicator, and a controller coupled to the electrode and the indicator. The controller is configured to operate, in a mutually exclusive manner, either in a first mode of operation to transmit a signal of a first system via the electrode and to receive an uplink signal transmitted from a sensor which detects, based on the signal of the first system, a position of the active stylus, or in a second mode of operation to transmit a signal of a second system via the electrode. The controller is configured to control the indicator responsive to a detection of the uplink signal.
