Original Abstract Submitted
Systems and methods are provided for determining driver surprise. The system can receive image data of a driver's pupils and video data of the driver's face over a time interval and determine a diameter of the driver's pupils over the time interval based on the image data. This diameter can be used to generate a pupil confidence value based on the diameter over the time interval. The system can extract facial features from the video data and generate a facial confidence value based on the facial features. A first weight can be applied to the pupil confidence value and a second weight can be applied to the facial confidence value to determine whether the driver is expressing surprise.
