Abstract: A method and system for maintaining operator alertness comprises a detector for detecting a physical status of an operator. The physical status indicates a first level of operator alertness. A user interface requests a second level of operator alertness from a self-evaluation of the operator at a request time. An evaluator measures at least one of an accuracy of the operator response to the requested input and a response time of the operator from the request time. An alert module generates alarm data or an alarm signal to alert the operator based on the first level of operator alertness indicating an inattentive state and at least one of the measured accuracy and operator response time indicating the inattentive state.

Abstract: A method and system for remotely monitoring and controlling a vehicle comprises a remote user interface for establishing a first model of a work area representative of the real world or an environment around the vehicle. Sensors collect data on a second model of the work area. Each of the sensors is associated with the vehicle. An evaluator determines a material discrepancy between the first model and the second model. A transmitter transmits the material discrepancy to a user remotely separated from the vehicle. A display module displays data from at least one of the first model, the second model and the material discrepancy to a user for resolution or classification of the discrepancy.
