The system’s purpose is to look for any signs of fatigue, distraction, anger or similar states in order to trigger the appropriate safety measures when necessary. The monitoring includes detecting where the driver’s head is, where they are looking, whether they are drowsy, etc. The mail goal is to ensure that the driver is remains focused on the driving.

Such information is valuable in case of an emergency, but it can also help increase the general safety of the passengers (for example, it can warn the parents about a child being left unattended in the vehicle).
FaceAnalysis can also estimate emotions of the driver and the passengers. For example, it can detect “undesirable” emotions such as anger in order to take the necessary safety measures such as playing relaxing music or slowing the car down.
