My research work has focused on applying low-level theories of cognition and perception to complex applied
problems with the goal of understanding how cognition unfolds under these circumstances. I believe this approach serves to better inform the basic theories
of cognition and perception while also providing insight into important applied problems.
I have taken this approach in several areas, such as:
- Cognition of graphs and visualizations
- Task interruptions and resumptions
- Understanding and predicting procedural errors
The majority of my research work has relied on using eye movememt measures as indicators of cognitive process. Currently, my focus is on understanding and predicting procedural errors using eye movements. This research project has resulted in the development of a real-time eye gaze system that monitors a user's eye movements and predicts (with fairly high accuracy) when the user is going to make an error before the user actually makes the error. Thus far, I have focused on postcompletion errors; I am now working towards understanding other types of procedural errors.
