Facial analysis for vehicle entertainment system metrics

A vehicle entertainment system comprising:

• a plurality of video display units configured to be mounted to fixed surfaces within a vehicle, wherein each of the video display units comprises:
• a display device configured to provide content to a user;
• a camera configured to output a camera signal containing data representing the user's face;
• and
• a processor configured to process the camera signal to identify facial features, to compare the facial features to defined demographics rules, to identify user demographics based on the comparison of the facial features to the defined demographics rules, to correlate the user demographics to a timeline of content consumed by the user through the video display unit to generate enhanced content usage metrics, to process the camera signal to determine an eye viewing location on a display device of the video display unit, and to correlate the eye viewing location to the timeline of content consumed by the user through the video display unit to further generate the enhanced content usage metrics;
• a communication interface configured to communicate with a central content usage analysis computer;
• and
• a metrics computer within the vehicle, the metrics computer is communicatively connected to determine the departure city and/or flight duration, to receive the enhanced content usage metrics from the video display units, to combine the enhanced content usage metrics with the departure city and/or the flight duration to generate anonymized enhanced content usage metrics through numerical statistics that hide individual values of the received enhanced content usage metrics, and to communicate the anonymized enhanced content usage metrics from the vehicle through the communication interface for delivery to the central content usage analysis computer separately located from the vehicle.
