We have used eye-tracking in most of our studies in NELL. Some data are really interesting, in other projects we didn’t learn as much. Why is that? Here are some ideas what to watch out for when planning an eye-tracking study.
- Eye-tracking data needs to be combined with other data sources. We found that in many cases the eye-tracking data could be interpreted in a meaningful way only when looking at interview responses of that person at the same time. Unless tasks are short, unambiguous and deterministic, the observed gaze behaviour may have a variety of reasons.
- Eye-tracking helps to improve design. Did users look at that image? How long did it take them to notice the button? What attracted their attention first? These are questions that eye-tracking can answer and that may inform design decisions.
- Eye-tracking may be more effective in later stages of the design process. Once you have a full mock-up quantitative analysis of gaze behaviour, heatmaps, etc. can be very informative. In contrast, wireframes or other early prototypes are probably better evaluated with qualitative feedback. For example, we explored which type of information learners would use when looking for help from a peer. We created three different mock-ups of the PeerFinder component and compared both the eye-tracking results as well as their preferences.
After all, User Experience is really all about selecting the right methods at the right time for the given target group and given tasks. I frequently tell my students that they have to be able to evaluate the strengths and weaknesses of a method in a given situation. Eye-tracking is one of many data collection methods. It may be used in a number of different ways.
This blog gives a good overview of the advantages and disadvantages of eye-tracking: The eye is the mirror to the soul? What does eye-tracking research tell us?

Just came across this funny piece: 15 Signs You Work in UX. It’s a great way to reveal some of the stereotypes as well as true values of the UX profession.
I guess, it’s not as funny if you are not deeply involved, but some of the signs made me laugh out loud. My favourite is: “Your mum is a persona.” While I never used her photo in any personas and have no intention to do so, I admit that I have referred to “people like my mum” numerous times when explaining the shortcomings of a particular interface. And I am surely not the only one to do so.
Btw., we are thinking of getting her a tablet for Christmas, but please don’t tell her. I am keen to see how she is going to explore the new interface (orientation phase), how long it will take her to send an email (learnability) and whether we have to show her how to switch it on a week later again (memorability). Sign number 16: “Your mum is a study participant.”

UXPA Ireland is the Irish chapter of the User Experience Professionals’ Association. The UXPA promotes collaboration and excellence in UX and supports individuals who are involved in the research, design, and evaluation of user experiences. We plan to organise a number of talks and workshops on hot topics, maybe a job fair and other activities that are useful for UX professionals.
The official launch of UXPA Ireland will take place on November 8, 2012.
Our guest speaker will be Tom Tullis, author of Measuring the User Experience and Beyond the Usability Lab. Tom is Adjunct Professor at Bentley University and VP of User Experience Research at Fidelity Investments.

Sebastian Thrun from Udacity probably read my last post on Massive Open Online Courses. At least that could be the motivation behind his latest idea: He aims to teach the largest on-line class ever. I don’t know where the current record stands, but this one will be large for sure. The Intro to Statistics course will start on June 25, 2012 and promises to be an interesting endeavour.
Meanwhile, I have completed the Web Application Engineering course “with highest distinction”, including all homework and final. I loved it! I learnt how to use Google App Engine and Python and created a wiki system with login, editing and history functionality. The instant feedback to submissions makes it easy to see your progress.
So, if you always wanted to learn about stats, this is your opportunity. See you there!

For years and years, one of the main arguments proposed in favour of using learning technologies has been: “It scales!” Whether there are ten, a hundred or a thousand students in your class, it doesn’t matter. We used this argument in the early days, when developing adaptive on-line courses for students at the University of Education in Freiburg. And yes, we had a couple of hundred students every year. We used the very same argument when designing courses in software engineering at Fraunhofer IESE. And yes, at lot of learners came.
There are lots of examples, where learning was brought in based on the promise that you could reach a large audience in an easy way. But I always felt that e-Learning had never really delivered on this promise. A course for a couple of hundred students. Good. A training solution for several thousand employees in a company. Nice. But only recently, we have seen examples of real scale. More than 100,000 people registered for a free on-line course on Artificial Intelligence offered by Stanford University. And 25,000 of them actually finished. Yes, that’s 25,000 people completing a hard, technical university course! Based on this success they have now started Udacity, a growing set of on-line lectures (all of them in Computer Science so far).
The phenomenon has been coined Massive Open Online Courses, MOOC, by George Siemens back in 2008 (see interview). Only now, it really gets massive. Similar offers are available from academic room and the by now well known MITx.
But we don’t even have to look that for to see the emerging trend. My esteemed colleague Eugene just celebrated the 1,000,000th view on his YouTube channel Learn with Dr Eugene O’Loughlin. The first million is always the hardest, but I am confident we will all soon be millionaires.
