[edit] Human–computer interaction

I reverted your recent edit to Human–computer interaction because issues of effectiveness and efficiency don't directly corrolate to usability and usefulness. I'm not sure what you were trying to get at. Perhaps you should bring it up on the talk page. A reference would be useful as well. --Ronz 02:49, 11 February 2007 (UTC)
