Usability testing methods have not changed significantly since the origins of the practice. Studies typically measure time on task, success/failure, error types, etc. Some questions cannot be answered with these techniques. Imagine a user spending longer than expected looking at a screen without making appropriate selections. Is the user overlooking the appropriate control or distracted by another display element? Does the user see the control, but not comprehend its meaning? User's eye movements can offer additional insight.

Workshop Sub-topics:

1. Incorporating eyetracking in usability tests

• What questions are best addressed with this data?
• How does eye position data fit with other usability data?
• What eye movement measures are useful?

2. Interpreting eye movement data

• How to best process raw data?
• Do measures correspond to cognitive processes?
• Can we interpret data using theories of other disciplines using eye tracking?

3. Resolving technical issues with the eye tracking technology

• Which tracking technology is best?
• What type of calibration process is needed?
• How is the user constrained?

We welcome participation of anyone experienced in usability evaluation or eye movement research. Participants will be selected based on position statements that address questions listed in at least one of the three subtopics above, and a description of your work. Selection criteria are familiarity with the topic and potential for innovative contributions.
