Abstract
An embodiment takes the form of a training server that presents a video comprising a plurality of frames, each comprising a respective scene representation of a scene at a respective time. The scene representations comprise respective representations of a feature in the scene. The training server presents a respective gaze representation of a driver gaze for each frame. The gaze representations comprise respective representations of driver gaze locations at the times of the respective scene representations. The training server generates an awareness prediction via a neural network based on the driver gaze locations, the awareness prediction reflecting a predicted driver awareness of the feature. The training server receives an awareness indication associated with the video and the gaze representations, and trains the neural network based on a comparison of the awareness prediction with the awareness indication.
