Eye Tracking: Dynamic Stimuli
This exciting course will focus on the analysis of dynamic stimuli, using EyeLink software. Eye tracking participants while they engage with dynamic stimuli (such as animations, videos and live websites) opens up fascinating new areas of research - but also poses a number of important challenges - both for the presentation of stimuli, and the analysis of the resulting eye tracking data. This advanced workshop is aimed at existing EyeLink users who want to learn how to use dynamic stimuli in their eye tracking research. We will cover all aspects of working with dynamic stimuli, from understanding the importance of video frame-rates and codecs, through to understanding the implications of dynamic interest areas for common eye tracking metrics such as dwell time and fixation count.

-
Understand how to use Screen Recorder to record data whilst people interact with websites / software and, including video gaming devices.
-
Learn how to use Data Viewer to create dynamic interest areas / dynamic heatmaps / time course analyses and more.
Schedule
09:00 - 09:30: Registration / Welcome
09:30 - 10:00: Introduction to Working with Dynamic Stimuli:
The workshop will begin by outlining a range of research scenarios in which using dynamic stimuli is important, and introduce some of the issues for stimulus presentation and data analysis that arise when using dynamic stimuli.
10:00 - 11:00: Creating and preparing dynamic stimuli for Experiment Builder:
This session will introduce a variety of software that can be used at all stages of working with dynamic stimuli – for example video conversion / resizing tools. The session will involve hands on practice with using the SplitAVI tool that accompanies Experiment Builder. The session will also demonstrate how to achieve accurate audio / video synchronisation.
11:00 - 11:30: Tea / Coffee Break
11:30 - 12:30: Presenting Dynamic Stimuli with Experiment Builder:
In this session you will gain hands on experience of using Experiment Builder to present video stimuli. The session will also cover the use of Experiment Builder's in-built animation functions.
12:30 - 13:30: Lunch
13:30 - 15:00: Screen Recorder:
This session will demonstrate how to use Screen Recorder software in conjunction with Data Viewer to record and analyse eye movements whilst participants interact with websites / other software - scenarios in which the participant, rather than the experiment has control over what appears on screen.
15:00 - 15:30: Tea / Coffee Break
15:30 - 17:00: Analysing Dynamic Eye Tracking Data in Data Viewer:
Using prepared viewing sessions, you will learn a range of techniques, including creating Dynamic Interest Areas , Dynamic Heat Maps, and outputting and interpreting Interest Area and Time Series (binning) reports.
