Visual scan path analysis using eye tracking data

Ziho KangIndustrial and Systems Engineering


Research focus

Characterizing eye tracking data through data analysis algorithms. E.g. Visual scanning sequence comparison methods, or clustering methods.

Evaluating human performance. E.g. Whether individuals were interrogating aircraft pairs (or groups) that would collide.

Using eye tracking data as a learning method.

E.g. Using experts’ eye tracking data to teach the novices.

Current application

Air traffic management (collaborating with FAA Civil Aerospace Medical Institute)


Collaboration opportunities through eye tracking research

Develop (full) automation methods for data analysis and visualization: E.g. Characterizing complex scan paths.Develop effective methods on human performance analysis: E.g. Workload.

Apply eye tracking research in different research areas:

E.g. Healthcare (autism), Education (reading), Weather system (forecasting).

Develop mixed methods approach: E.g. Brain wave data, key input data, verbal/written reports.

Available resources

State-of-the-art eye tracker(s) to be purchased with the sampling rate at 250-500
