Combination touch and transducer input system and method

A position indicator for use in an input system including the position indicator and a sensor, the sensor including an array of electrodes and configured to detect a position of the position indicator on the array of electrodes, the position indicator comprising:

• a tip configured to generate an electric field that induces signals in the array of electrodes, wherein the electric field is driven by a driving signal having an amplitude and a first frequency without being phase-modulated;
• an indicator controller configured to determine data including one of pressure information indicative of a pressure applied to the tip of the position indicator, switch information indicative of an operation state of a switch provided on the position indicator, identification information of the position indicator, tilt information of the position indicator, or rotation information of the position indicator;
• and
• a transmitter, provided separately from the tip, and configured to
• asynchronously transmit the data to the sensor as digital data, using a wireless communication protocol at a second frequency that is different from the first frequency.

An integrated circuit configured to control operation of a position indicator used with a sensor, the sensor including an array of electrodes and configured to detect a position of the position indicator on the array of electrodes, the integrated circuit comprising:

• control circuitry configured to:
• generate, at a tip of the position indicator, an electric field that induces signals in the array of electrodes, wherein the electric field is driven by a driving signal having an amplitude and a first frequency without being phase-modulated;
• and
• determine data including one of pressure information indicative of a pressure applied to the tip of the position indicator, switch information indicative of an operation state of a switch provided on the position indicator, identification information of the position indicator, tilt information of the position indicator, or rotation information of the position indicator;
• and
• communication circuitry, provided separately from the tip, and configured to
• asynchronously transmit the data to the sensor as digital data, using a wireless communication protocol at a second frequency that is different from the first frequency.
