1. An interactive display system, comprising:

  • an input device including an electrode tip and an input device-side radio transceiver;

    wherein the input device is configured to communicate over an electrostatic link formed between an electrode matrix of an interactive display and the electrode tip of the input device,wherein the input device is configured to detect a position signal, and to transmit data to the interactive display via a radio link between the input device-side transceiver and a display-side transceiver of the interactive display, andwherein the input device is configured to sever the radio link and power down the input device-side radio transceiver if the input device has been separated from the interactive display by at least a threshold distance for at least a threshold duration, the threshold distance being one of less than an outermost limit of a range of the electrostatic link and the outermost limit of the range of the electrostatic link.
