Claim One:
1. A method for monitoring vehicle operator fatigue, the method comprising: receiving a plurality of different biometric data related to a vehicle operator from a plurality of biometric sensors during real time operation of a vehicle; calculating a fatigue level for the vehicle operator by applying the received biometric data to a statistical model of fatigue, wherein the statistical model of fatigue outputs an indication of the calculated fatigue level for the vehicle operator, wherein the statistical model of fatigue is created by: recording biometric data about the vehicle operator from the plurality of biometric sensors during a plurality of previous operations of the vehicle, wherein each of the plurality of previous operations corresponds to a respective fatigue level of a plurality of corresponding fatigue levels of the vehicle operator relative to a predefined numerical scale, each of the plurality of corresponding fatigue levels being at least one of: known, assumed, and self-reported by the vehicle operator; and performing statistical analysis on the recorded biometric data to determine the statistical model of fatigue by ascertaining which statistical model of fatigue results in a best fit of the recorded biometric data to the plurality of corresponding fatigue levels for the plurality of previous operations.
