Award [2] for a clear description of augmented reality, [2] for a clear explanation of how an image could be sent to the expert surgeon, and [2] for the role in the operation (up to [6 max]).

AR:
Augmented reality projects digital/additional information;
onto a real-time situation/onto the real world;

Augmented reality allows an actual situation to be complemented in such a way;
that essential information is added to a video image;

An expert surgeon in another place sees the operation as if they were there/as a video being filmed;

Tags attached to the affected area to be operated can be overlaid on the image;
Can overlay information on the view they have;

Transmission;
Annotated video data is continually streamed between the two;
Using a camera at the operation end;
In real-time over a (very) secure and fast network;
Viewed by expert surgeon on a screen;

Example of use;
The expert can show on the image what actions should be made (and where);
Allow example;
Using the information being sent back on a headset tablet/smart phone/transparent screen;
