Videoconferencing System Using QR Codes for Interaction

A server, comprising:

• a network interface;
• a processing unit operatively coupled to the network interface, the processing unit configured to:
• operatively communicate with a first device via the network interface,
• obtain information indicative of a request for the first device to interact in a videoconference with a second device,
• generate an optical machine-readable data representation encoding data of the request, and
• make the optical machine-readable data representation available to the first device via the network interface.

A videoconferencing method, comprising:

• submit, from a first device to a server, information indicative of a request to interact the first device in a videoconference with a second device;
• obtaining an optical machine-readable data representation from the server at the first device, the optical machine-readable data representation encoding data of the request;
• and
• making the optical machine-readable data representation available for decoding by the second device.

A first device, comprising:

• a display;
• a network interface operatively communicating with a server;
• and
• a processing unit operatively coupled to the display and the network interface, the processing unit configured to:
• submit to the server information indicative of a request to interact the first device in a videoconference with a second device,
• obtain an optical machine-readable data representation from the server, the optical machine-readable data representation encoding data of the request, and
• make the optical machine-readable data representation available for decoding by the second device.

A videoconferencing method, comprising:

• obtaining an image of an optical machine-readable data representation with a camera of a first device, the optical machine-readable data representation encoding information of a videoconference;
• decoding at the first device the information of the videoconference from the optical machine-readable data representation;
• and
• responding with the first device to the decoded information.

A first device, comprising:

• a camera;
• and
• a processing unit operatively coupled to the camera and configured to:
• capture an image of an optical machine-readable data representation with the camera, the optical machine-readable data representation encoding information of a videoconference,
• decode the information of the videoconference from the optical machine-readable data representation, and
• respond to the decoded information.

A first device, comprising:

• a display;
• a network interface operatively connected to a videoconference;
• and
• a processing unit operatively coupled to the display and and the network interface, the processing unit configured to:
• generate an optical machine-readable data representation encoding information of the videoconference conducted with the first device, and
• display the optical machine-readable data representation on the display for decoding by a second device.
