I had a basic grasp of what you were saying in your post but being the Curious George I am I had to learn more.
I ran a Google search for Human Computer Interface to better figure out what you were talking about and the Wikipedia post was the first thing in the search results.
I posted the Wiki piece to try to help other viewers of the thread to understand a bit more as I saw member_8880 post

It does seem to me the 2 terms are very closely related and almost interchangeable but I will look at learning a bit more about it and will more than likely see the differences.
