Only send me personal email if you really have to. Ask general questions about the course in the course newsgroup (see below). If you do have to send me personal email, please always state your name, group number, and Matrikelnummer. That makes you much easier to find.

Office Hour: By appointment (during CoViD restrictions).
Room D.2.16, ID01054, ISDS, Inffeldgasse 16c, 1st floor.

In general, I much prefer teaching face-to-face than online. However, due to CoViD restrictions, it will not be possible to teach everything face-to-face. The plan for this semester is:

  • Lectures will be held online with Webex. See my guide to Using Webex.

  • Client Meetings (Abgabegespräche) will be held face-to-face under the university's CoViD regulations.

  • Exams (MC Tests) will be held face-to-face under the university's CoViD regulations.

  • The Grading Review (Einsichtnahme) will be held face-to-face under the university's CoViD regulations.

If the CoViD situation demands, then the plan may have to change.

Sign up in groups of 4 on TUGRAZonline.
Starting Mon 21 Feb 2022 14:00.
Ending Sun 27 Feb 2022 23:59.
Registration has now closed.

Form your own groups. If you have friends and colleagues who you know you can work well with, coordinate in advance and all sign up for the same group at the same time. Depending on the exact number of participants, there may end up being a few groups of three rather than four.

If all the groups are full, I will create new groups as necessary. However, I will only do this once most of the existing groups are full, so that groups are spread fairly evenly across the tutors. For internal accounting reasons, one or more of the tutors may sometimes have less groups than the other tutors.

If you do not know anybody else, sign up for any group with a free place and contact the other group members by email using the "Mail an TeilnehmerInnen" function in TUGRAZonline. Do not post "I am looking for a group" or "Who else is in my group?" messages to the course newsgroup.

If you register for the course, but later decide not to participate, please have the courtesy to unregister from the course.

After the unregistration deadline, if you wish to unregister from the course, please contact me by email. Depending on how far the course has already progressed, I will either unregister you without penalty or (more likely) grade your work up to that point.

If you do not respond to emails from your group colleagues, or do not actively participate, I reserve the right to remove you from the course (with grade 5).

It sometimes happens that one group member does not actively participate and most (or all) of the work is done by the other group members. If this happens in your group and you feel you are carrying an inactive group member, let your tutor know and only write the names of the active group members on the reports you hand in.


For the practical exercises, it is assumed that you have good knowledge of HTML5 and some CSS3. You should also understand what plain text files and UTF-8 are.

If you do not have any prior experience of these, you may wish to refer to Section 2.2 (plain text and UTF-8) and Chapters 10 (Polyglot HTML5) and 11 (CSS3) of my INM 2014 course notes (or similar material elsewhere). HTML Dog provide good tutorials into HTML and CSS.

Aims and Objectives of Course:

Students will gain an overview of the theory of human-computer interaction. They will have an appreciation of how to design usable interfaces and will gain the knowledge necessary to perform heuristic evaluations and thinking aloud tests of user interfaces.

Teaching Method:

Lectures with integrated practical work.

Attendance Policy:

Attendance at these two online classes is compulsory:

  • Class 1 on Tue 01 Mar 2022 13:15-15:45
  • Class 3 on Tue 15 Mar 2022 13:15-15:45

You must use a webcam and microphone and you must turn them on as and when requested.

For the remaining online classes, I expect you to attend and will assume that you have been attending. It is your responsibility if you miss a class.

Participation in the exercises is compulsory. You are not allowed to skip one or more of the exercises.

Attendance at the Client Meetings (Abgabegespräche) is compulsory.

Attendance at the final written exam (MC Test) is compulsory.

[Unless you have a very good reason backed up by appropriate documentation, such as a doctor's letter.]

Assessment Method:

Your grade will be determined by a series of practical exercises. See practicals for more details.

Lecture Notes: [240 pages PDF]

The lecture notes are never in their final form, but will be updated periodically during the course.

If you teach and would like a zip file of the corresponding lecture slides (the same material but in HTML, SVG, PNG, and JPEG), please contact me by email.

Course Books:

I highly recommend the following books for the course:

Practical Exercises:
Course Newsgroup:

This is where I will post news and announcements and where you should ask any questions you might have. It is also the right place to look to see if your questions have already been answered.

If you are not familiar with newsgroups, you should refer to Chapter 2 of my INM 2014 course notes (or similar material elsewhere). There are rules and conventions you should respect. I recommend using Thunderbird as a news client.

Breaches of Academic Integrity:

Write in your own words. Copying the work of others (from the web, another group, or elsewhere) and then submitting the work as (part of) your own work is known as plagiarism and is a serious breach of academic integrity. Any text passages written by others, or images created by others, must clearly be identified as such. By taking this course, you agree to have your work submitted to plagiarism detection services. Your work may also be cross-checked against other work submitted in the same and previous years.

Assembling a collage of stolen text fragments, possibly with some slight editing or rearrangement, and handing them in as your own words is not acceptable, even if you reference the original source. If you are not well-practiced in the ways of academic citation (i.e. how not to plagiarise), I strongly recommend that you read Chapter 5 of my INM 2014 course notes and some of the resources on Debora Weber-Wulff's Plagiarism Portal web site.

If you help a fellow student in another group, be careful that you do not disclose your exact solution or work. If the group you help submits substantially identical work to your group, both groups will be punished for plagiarism.

Do not fake. Faking data (for example, inventing the list of problems for a heuristic evaluation) is a serious breach of academic integrity.

The university has a code of conduct, a set of guidelines, and regulations regarding academic integrity. Breaches of academic integrity are very serious and will be punished appropriately where discovered.
