Display system with electrostatic and radio links
First Claim
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.

Abstract
Systems and methods for transmitting information in interactive display systems are provided. In one example, an interactive display system comprises an interactive display including an electrode matrix, a display-side radio transceiver, and an input device including an electrode tip and an input device-side radio transceiver, wherein the interactive display is configured to communicate over an electrostatic link formed between the electrode matrix of the 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, and wherein 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.

11. A method of transmitting information between an interactive display and an input device, the method comprising:
-
transmitting a channel identifier to the input device via an electrostatic link formed between the interactive display and the input device; and receiving a parameter from the input device via a radio link formed between a display-side radio transceiver in the interactive display and an input device-side radio transceiver in the input device, the parameter received on a channel of the radio link identified by the channel identifier, wherein 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. - View Dependent Claims (12, 13, 14, 15, 16)

17. An input device, comprising:
-
an electrode configured to electrostatically receive data from an interactive display; an input device-side radio transceiver; a processor; and memory holding instructions executable by the processor to; determine a channel identifier based on the electrostatically received data; transmit data indicating a position of the input device via a radio link formed between a display-side radio transceiver of the interactive display and the input device-side radio transceiver on a channel identified by the channel identifier; and 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 the threshold duration. - View Dependent Claims (18)
