Introduction to Eye Tracking Usability Studies

A brief introductory to usability testing using eye tracking technology.

Transcript

1. Why Eye Tracking?
2. Why Eye Tracking See where users are looking How long they are looking Path of focus from item to item
 What parts did they (seemingly) miss
3. What Can’t Eye Tracking Tell Us?
4. Eye Tracking Cannot Tell … Why certain elements get more attention than others Which items are in peripheral vision
 Whether users understand or are aware of the content they looked at
5. How Does It Work?
6. How Eye Tracking Works Hardware device focuses on pupil of participant’s eye Determines direction and concentration of their “gaze”
7. How Eye Tracking Works Typically Start With Calibration For best data, don’t ask user to “think aloud” during test (can do retrospective later)
8. How Eye Tracking Works Fixation: maintaining visual gaze on single location for a specific amount of time. Saccade: movement of the eyes between fixations
9. How Can We Interpret Eye Tracking Data?
10. Interpret Eye Tracking Heat maps Saccade paths (gaze plot) Numerical Data (fixations, time spent, time to first fixation) Qualitative Interpretation
11. Interpret Eye Tracking
12. Types of Eye Trackers
13. Types of Eye Trackers Screen-Based Portable Wearable
