FIELD: calculating; counting.
SUBSTANCE: invention relates to computer engineering. System comprises an interactive display including an electrode matrix having row and column electrodes, wherein the interactive display also includes a display-side radio transceiver; an input device including an electrode tip and an input device-side radio transceiver; wherein the interactive display is configured to transmit a channel identifier in an electrostatic link formed between the electrode matrix of the display and the electrode tip of the input device, and wherein the input device is configured to detect a position signal indicating a nearest row electrode in the electrode matrix adjacent which the electrode tip is positioned, and to transmit data indicating the nearest row electrode to the interactive display via a radio link between the input device-side transceiver and the display side transceiver on a channel of the radio link identified by the channel identifier.
EFFECT: technical result is to enable the transmission of information in an interactive display system.
