• Live Eye Gaze (real-time)
• Analyze users intention and their behaviour
in areas where users would expect specific
interactions
• Quantitative data (Fixation counts, revisits, ..)
• Visualisations (heat map)
• Illustrate areas of interest
• Analyze more complex data (find unnoticed
areas, needlessly complex interactions)

14. C O M B I N I N G E T A N D TA
•Qualitative TA-Data (User speaks out loud)
• Analysis of verbal in-play probes (+/-)*
• Analysis in-play responses (Bored, Frustrated, Lost,
