Advanced topics in eye tracking: Classification of eye movements

Daniel Scheffold, a Tobii Certified Instructor from Tobii Pro has started a 4-part series of advanced topics in eye tracking.logo_pro

Check it out below!


This is the first part of four in our mini-series on advanced topics in eye tracking. We begin with a topic that is fundamental to the technique: classification of eye movements.
 
Why do we need to classify eye movements in the first place?
 
Most modern eye trackers are video-based. Images of the eye captured at regular intervals, the sampling rate, are processed to calculate instantaneous gaze position. This discrete data stream must then be converted back to the informative, continuous eye movements for analysis. This digital-to-analog conversion is accomplished by passing the raw gaze samples through an event detection algorithm called the fixation filter.
 
Fixation filters can come with adjustable parameters to enable tailoring their characteristics to specific circumstances. Choosing the appropriate parameters is of fundamental importance in properly classifying eye movements and calculating valid metrics based on the resulting fixations and saccades.

How do I apply it?
 
There are a variety of fixation filters and researchers may choose based on those commonly used in their field. If using Tobii Pro Studio for analysis, you can choose from several with varying levels of complexity and adjustability.
 
The Tobii Pro Studio default is the Tobii I-VT fixation filter. As a classification filter that operates on the velocity of eye movement, it is effective and commonly used in human behavior research.
You can find the algorithm description here: Download White Paper: Tobii I-VT Fixation Filter

Tip: As reviewers get more demanding and want to understand better how you processed your data, we encourage you to cite this White Paper and the parameters chosen in your methodology section if you use this filter.

Our White Paper on the Default Values Tobii I-VT Filter describes how we determined the optimal parameter values of the Tobii I-VT Fixation Filter.

As this is a generic eye movement filter, it is reasonable to review and validate the parameters of your eye movement filter empirically. You find a great hands-on guide for this is in Chapter 5.3, pp. 153 in “Eye Tracking – A Comprehensive Guide to Methods and Measures” from Holmqvist & Nyström et al. (Oxford University Press, 2011). In Tobii Pro Studio, the Velocity Chart can aid you in this process (see Tobii Pro Studio manual Appendix 14.2)

To summarize, how you classify eye movements in your data is an extremely important step in your research and can have a massive influence on the calculated measures, so choose carefully.

If you’d like to learn the basics of eye movements and events (e.g. what are fixations, saccades, smooth pursuit, vergence, VOR), we touched base on it in this article here.

Next up…we will be taking a deeper look at the three different spaces used in eye tracking and how they relate to drawing areas-of-interest. Watch out for the article on eyetracking.com.sg!

What did we learn at the Innovation Labs World?

On 27 September 2016, we attended Innovation Labs World in Singapore as an exhibitor, displaying Tobii eye tracking equipment and our research consultancy services, engaging with the public sector. Indeed, there was copious amount of interest in eye tracking from the various government agencies – thanks to GovTech’s Government Digital Services Hive UX Lab where they use a Tobii Pro X2-30 screen-based eye tracker for their UX research!

But this event was more than just about showcasing the equipment. It gave us a glimpse into the future that beheld Singapore’s design, technology and IT sector for public service innovation.

Po29936699781_2e335d0ae1_klitical momentum has triggered the creation of new innovation labs, smart city units and digital services. Various representatives from Singapore’s Smart Nation strategy to India’s drive for 100 Smart Cities, and from Australia’s Digital Transformation Office to Makassar’s “War Room” were present at Innovation Labs World. GovTech, the newly formed agency aiming to build deep tech capabilities in the Singapore Government and to drive its digitalisation efforts was also present at this event.

Using tech and the harnessing of data to engage citizens, build better environments and the development of health and innovation policies were some case studies put forth by experts around the world.

We’re really excited that we were part of this and for the future going forth.

Our favourite read: Eye Tracking the User Experience: A Practical Guide to Research by Aga Bojko

Among all the books that discuss about eye-tracking and user experience, our personal favourite has to be:

eye-tracking-the-user-experience

Eye Tracking the User Experience

A Practical Guide to Research

By Aga Bojko

As you might have expected, this book will teach readers how to do eye-tracking studies the right way, choosing the right device, analysing and presenting the right way, and so on and so forth…..Yes, it virtually covers every aspect of what you need to know and consider before adding eye-tracking to your research toolkit.

Richly illustrated and clearly witten, this book stands apart from similar books in that it presents information in an approachable and accessible way. Despite all the technical bits, reading it certainly did not give us the feelings of reading a textbook!

 

However, the main reason why we like this book is the main theme that runs throughout the book: “Think first, Track later”. Aga Bokjo advocates that eye-tracking will not always be the most appropriate research methodology, unless the data it generates can be used to answer particular research objectives. Check out an excerpt for the book here.

By being brutally honest about the real benefits and limitations of eye-tracking, this book offers a refreshing take on the controversial research method. Coming from a background that blends rigorous academic research with an abundance of UX industry experience, Aga Bokjo gives us “actionable insights” and guidance to adopting (or not) the eye-tracking research methodology. Because of the scientific rigour that Aga Bokjo tries to instill in readers, this book appeals not only to the UX industry, but to the academic world as well.
