Classifying Cognitive Load and Driving Situation with Machine Learning

This paper classifies a driver's cognitive state in real driving situations to improve the in-vehicle information service that judges a user's cognitive load and driving situation. We measure the driver's eye movement and collect driving sensor data such as braking, acceleration, and steering angles that are used to classify the driver's state. A set of data about the driver's degree of cognitive load, regarded as a training set, is obtained from steering operation and task cognition. Given such information, we use a machine-learning method to classify the driver's cognitive load. We achieved reasonable accuracy in certain driving situations in which the driver moves abnormally for an appropriate service supporting safe driving.
