Details of sessions
The Tobii Session will include:
- An overview of the different Tobii systems for adult and child multimodal studies
- Introduction to in-house software Tobii Studio
- Using text, pictures and videos with Tobii Studio: Issues to remember/consider
- Demonstration of programming a multimodal experiment with Tobii Studio
- Demonstration of a multimodal experiment with Tobii Studio: calibration and running an experiment, data visualisation and handling
- Different eye-tracking paradigms and tasks with Tobii via Tobii Studio
- Different eye-tracking paradigms and tasks with Tobii via E-prime, Matlab and Psychopy
The Eyelink Session will include:
- An overview of the Eyelink 1000 system and associated software packages (e.g. Data Viewer & Experiment Builder)
- Demonstration of the calibration procedure & running an experiment
- Demonstration of the gaze-contingency paradigm
- Demonstration of the visual-world paradigm
- Short demonstration on how to programme an experiment

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.
