1. A system comprising:
a position indicator that includes:
a case having a plurality of reference tags disposed on an exterior surface of the case;
a core body disposed within the case and having a tip that protrudes from the case through an opening in the case;
a pressure detector which, in operation, detects a pressure applied to the tip of the core body; and
a transmitter coupled to the pressure detector, wherein the transmitter, in operation, transmits one or more signals indicative of the pressure applied to the tip of the core body; and
a processing device that includes:
a sensor having an input surface, wherein the sensor, in operation, detects the position indicator and outputs a signal indicative of a position of the position indicator on the input surface of the position indicator as sensed by the sensor;
at least one receiver which, in operation, receives the one or more signals indicative of the pressure applied to the tip of the core body of the position indicator and one or more signals indicative of one or more respective positions of one or more of the reference tags;
at least one processor coupled to the at least one receiver;
at least one memory device that stores instructions which, when executed by the at least one processor, cause the processing device to generate visualization data based on the one or more signals indicative of the pressure applied to the tip of the core body of the position indicator, and the one or more signals indicative of the one or more respective positions of the one or more of the reference tags, and the signal indicative of the position on the input surface of the position indicator as sensed by the sensor, wherein the visualization data describe an object that extends from a predetermined position in a direction that is based on the one or more signals indicative of the pressure applied to the tip of the core body of the position indicator, and wherein the visualization data are provided for display by a visualization device.
