A vehicle entertainment system includes a video display unit and a user interface (UI) control processor. The UI control processor is configured to receive passenger attributes sensed from the passenger operating the video display unit, generate a passenger metric that characterizes the passenger based on the attribute, and control a UI of the video display unit based on the passenger metric. The passenger metric may be a passenger demographic metric determined based on facial features of the passenger. The passenger demographic metric may be a passenger emotion metric, a passenger attentiveness metric, a passenger UI operational effectiveness metric, a passenger biometric feature metric, etc.
