Abstract
An interactive media device. The device has an area for receiving a document and a sensor network adjacent to the area. The sensor network has a first region adjacent to the document and responsive to user proximity to the first region. The sensor network has a second region that is responsive to markers disposed on or embedded in the document. The device has a processor coupled to the sensor network and able to receive signals from the sensor network indicating capacitance change in the first and second regions based on the received signals. The processor is thus able to identify a location in the document based on the first and second received signals.
