Workshop: Working with Eye-tracking

Wed 25th June 2014

This workshop will give an insight into how to design eye-tracking experiments for language research, record eye-tracking data, and analyse data using R.

  • Dr Tim Holmes, Technical Director, Acuity Intelligence Ltd.
  • Dr Sam Hutton, University of Sussex
  • Dr Serge Sharoff, Senior Lecturer in Translation Studies, University of Leeds

Details of sessions

The Tobii Session will include:

  1. An overview of the different Tobii systems for adult and child multimodal studies
  2. Introduction to in-house software Tobii Studio
  3. Using text, pictures and videos with Tobii Studio: Issues to remember/consider
  4. Demonstration of programming a multimodal experiment with Tobii Studio
  5. Demonstration of a multimodal experiment with Tobii Studio: calibration and running an experiment, data visualisation and handling
  6. Different eye-tracking paradigms and tasks with Tobii via Tobii Studio
  7. Different eye-tracking paradigms and tasks with Tobii via E-prime, Matlab and Psychopy

The Eyelink Session will include:

  1. An overview of the Eyelink 1000 system and associated software packages (e.g. Data Viewer & Experiment Builder)
  2. Demonstration of the calibration procedure & running an experiment
  3. Demonstration of the gaze-contingency paradigm
  4. Demonstration of the visual-world paradigm
  5. Short demonstration on how to programme an experiment

Slides from the session are available here: Hutton_Eyelink

Introduction to R:

This session will provide a very short introduction into using R to provide statistical analysis of data, in particular, focusing on examples from eye-tracking studies.  I will introduce the basics of data management in R, the use of statistical tools, as well as graphics.

R is an open-source tool, which can be freely downloaded from its project website: http://www.r-project.org/

It comes with a fairly powerful command-line interface.  However, to shorten your learning curve a graphical environment, such as the RStudio IDE is recommended.  It is also an open-source project, which can be downloaded from http://www.rstudio.com/

It will be expected that the participants come with their laptops with working installations of R and RStudio.

Slides from the session are available here Sharoff_2014-eye-R.
