1. A system for detecting impairment of a vehicle operator, the system comprising:
a wearable mobile device including:
a frame for supporting the wearable mobile device on the operator's head;
a power source for powering electronic components of the wearable mobile device;
an accelerometer for sensing acceleration of the wearable mobile device and for generating acceleration vector data; and
a processor configured to receive acceleration vector data from the accelerometer and to determine impaired operator events based on such acceleration vector data,
wherein the processor is configured to instruct the wearable mobile device to generate an alert when an impaired operator event is detected, and
wherein the processor is further configured to receive inputs from the operator for altering parameters used in determining whether an impaired operator event constitutes actual operator impairment.
