A Regression-based User Calibration Framework for Real-time Gaze Estimation

Jean-Philippe Thiran, Nuri Murat Arar, Hua Gao

Eye movements play a very significant role in human computer interaction (HCI) as they are natural and fast, and contain important cues for human cognitive state and visual attention. Over the last two decades, many techniques have been proposed to accurat ...

Action Units and Their Cross-Correlations for Prediction of Cognitive Load during Driving

Jean-Philippe Thiran, Gabriel Louis Cuendet, Anil Yuce, Hua Gao

Driving requires the constant coordination of many body systems and full attention of the person. Cognitive distraction (subsidiary mental load) of the driver is an important factor that decreases attention and responsiveness, which may result in human err ...
