1. A system, comprising:
- a motion sensor system configured for deployment in a cab of a vehicle operated by a driver and to generate substantially in real-time a digital mapping of driver movement using structured light during operation of the vehicle, the motion sensor system configured to compute a depth map of a portion of the driver'"'"'s body using the structured light;
an audio sensor configured for deployment in the cab and configured to generate an audio signal responsive to driver movement during operation of the vehicle, the audio sensor configured to operate in a listening mode;
a computer configured for deployment in the cab and coupled to the motion sensor system and the audio sensor, the computer configured to generate a trigger signal in response to an output of the audio sensor while operating in the listening mode;
a driver behavior detector coupled to the computer and configured to detect a driver distraction event using the driver movement mapping and the audio signal; and
a communication device at the vehicle and configured to communicate an alert message to one or both of a user interface device in the cab and a remote system in response to the detected driver distraction event;
wherein the motion sensor system is configured to generate substantially in real-time the digital mapping of the driver'"'"'s face in response to the trigger signal.

Abstract
A system includes a motion sensor system configured for deployment in a cab of a vehicle and to generate substantially in real-time a digital mapping of driver movement during operation of the vehicle. A computer is configured for deployment in the cab and coupled to the motion sensor system. A driver behavior detector is coupled to the computer and configured to detect a driver distraction event using the driver movement mapping. A communication device at the vehicle is configured to communicate an alert message to one or both of a user interface device in the cab and a remote system in response to the detected driver distraction event.

21. A method, comprising:
-
generating substantially in real-time a digital mapping of driver movement using structured light during operation of a vehicle, wherein generating the digital mapping comprises computing a depth map of a portion of the driver'"'"'s body using the structured light; generating audio signals responsive to driver movement during operation of the vehicle; generating, in a listening mode, a trigger signal in response to detecting an audio signal indicative of suspect driver behavior; detecting a driver distraction event using the driver movement mapping and the audio signals; and communicating an alert message to one or both of a user interface device in the vehicle and a remote system in response to the detected driver distraction event; wherein the digital mapping of the driver'"'"'s face is generated substantially in real-time in response to the trigger signal.
