Special Note to Ph.D. Students: Welcome to this menu. I have posted a variety of lecture notes and materials that I use in my campus-based courses to provide you, the computer-based student, an opportunity to receive more information on HCI. Of course, I can only post text-based slides on our system, so missing are diagrams and graphics that generally go with many of the lecture slides. Most Ph.D. course sections include some face-to-face instruction. Therefore, most of you should have the "latest" lecture notes in hardcopy, including graphics, diagrams, etc. Consequently, you need not spend too much effort looking at the online version lecture notes! Of course, as I revise my lectures and come up with new things, I will post them in here for you to access. Dr. Dringus
