Eye Tracking at Night – RMIT University

A team of researchers at RMIT University led by Dr Jair Garcia and Assoc Prof Adrian Dyer tried the capacity of Tobii 2 Glasses to record in the highly complex lighting conditions at the famous ‘White Night’ event in Melbourne on the 18th February 2017.

Assoc Prof Adrian Dyer said, “We were pleasantly surprised at the capacity of the glasses to track subject eye movements despite, low light intensity levels and very dynamic changes in illumination conditions The team member shown in the black jacket is filming the amazing art displays near RMIT, and the tablet connected wirelessly to the Tobii Pro Glasses 2 allowed the team to simultaneously see what she was viewing on her camera screen as she composed the image, whilst also looking around at all the incredible art displays. The data allow the team to better understand individual experiences when visiting such a complex art installations.”

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.

TOBII PRO GLASSES 2 SOFTWARE UPDATE (July 2016)

Tobii Pro announced a new feature for Tobii Pro Glasses 2 software, which will help us simplify and streamline the behavioural coding process.

New Feature: Event Count (in Tobii Pro Glasses Analyzer)

TobiiPro_Glasses_Analyaer_UI_Behavioral_Coding_560x300

 

This latest feature of the Pro Glasses Analyzer allows you to measure the occurrences of instantaneous behaviours other than gaze, i.e. using events to mark and code relevant user behaviours. In addition, you can also apply the Time of Interest feature to measure the length and duration of these coded behaviours.

By combining gaze data with occurrence of other behaviours in our research, we can create advanced metrics that will enhance in-depth insights into human behaviour.

Other improvements to the Tobii Pro Glasses Analyzer includes:

  • Improved usability by making it possible to edit Custom Times of Interest in the Visualisation tab
  • Added Standard Deviation (N-1) and Variance to all Metrics
  • New columns added in data export: Date of export, Recording resolution, Recording Fixation filter, Gaze event duration
  • Improved Real-World Mapping performance and algorithm

We’re saving the Planet! Objective Eye Tracking and Prof. Gemma Calvert secure a grant from The Institute on Asian Consumer Insight!

We are proud and excited to announce that Objective Eye Tracking is collaborating with Prof. Gemma Calvert and her team of researchers at Nanyang Technological University on a grant project awarded by The Institute on Asian Consumer Insight (ACI).

This ground breaking research project will seek to understand Asian consumers’ sustainable living perceptions and how that translates into their shopping behaviors. The project tackles key strategic topics under the Possible Future Worlds research initiative at ACI. The mission for this project is to better understand how we can reduce the impact that humans have on Planet Earth.

We will probe into the consumers’ subconscious attitudes and emotions about sustainability, recycling and eco-shopping using cutting edge methods including the Implicit Reaction Time tests and Eye Tracking with the Tobii Pro Glasses 2. These methods will help us uncover new insights that are not easily accessible via regular self-report measures and derive new solutions that will help change human behavior and make a difference.
