I've started watching Voyager, finally, and I've noticed on more than one occasion, we see the Emergency Medical Holographic program (The Doctor) sitting at the desk in sickbay, working on the computer. In "Phage", he even makes a comment about having a lot of paperwork to do. Why? He is the computer, essentially. He could have a direct "mental" link to medical records, as well as medical references.
The only reason that comes to mind is that it's to make him seem more human. But that rationale only would make sense if he were intended to become a part of the crew. This happens on Voyager, but the EMH was intended to be a short-term emergency replacement. Building simulations of writing paperwork seems like a waste of both programmer effort and time that would be better spent during an emergency.
Is there another reason? Is this ever explained?
