Shared data and collaboration for head-mounted devices

A head-mounted device comprising:

• a camera for capturing a first view including a first physical object;
• a display;
• and
• a processor configured to:
• receive, with a communication element and from an additional head-mounted device, data based on a second view captured by an additional camera of the additional head-mounted device, the second view including the first physical object and a second physical object, the second physical object not being in the first view;
• determine a characteristic of the first physical object based on the first view captured by the camera and the data from the additional head-mounted device;
• transmit, with the communication element and to the additional head-mounted device, a signal indicating the characteristic of the first physical object;
• operate the display to output the first view with a virtual object that replaces the first physical object in the first view, the virtual object being based on the characteristic of the first physical object;
• output a representation of the second physical object based on the data received from the additional head-mounted device;
• determine whether the additional camera of the additional head-mounted device is arranged to capture the second view of the first physical object;
• and
• transmit, with the communication element and to the additional head-mounted device, a request for the data.

A head-mounted device comprising:

• a camera;
• a display;
• a communication element;
• and
• a processor configured to:
• capture a first view of a first physical object with the camera;
• receive, with the communication element, data from an additional head-mounted device comprising an additional camera, the data being based on a second view of the first physical object captured by the additional camera, the second view further including a second physical object that is not in the first view;
• determine a characteristic of the first physical object based on the first view and the data;
• transmit, with the communication element and to the additional head-mounted device, a signal indicating the characteristic of the first physical object;
• operate the display to output a virtual object as a substitute for the first physical object based on the characteristic of the first physical object;
• and
• output a representation of the second physical object based on the data received from the additional head-mounted device;
• and
• receive, with the communication element, arrangement information of the additional head-mounted device;
• and
• determine whether, based on the arrangement information, the additional camera is arranged to capture the second view of the first physical object.
