SYSTEM AND METHOD FOR CONTROLLING MACHINES USING OPERATOR ALERTNESS METRICS
A method includes determining a first task requiring one of a plurality of machines to traverse along a first route and determining a second task requiring the one of the plurality of machines to traverse along a second route. The method also includes determining a first route score for the first route, the first route score being at least in part indicative of a difficulty of traversing along the first route, and determining a second route score for the second route, the second route score being at least in part indicative of a difficulty of traversing along the second route. The method may also include receiving sensor data generated by a sensor associated with a first machine of the plurality of machines and determining, based at least in part on the sensor data, an alertness metric associated with an operator of the first machine. Based at least in part on the alertness metric being equal to or greater than a threshold alertness metric, the method may also include determining the first task for completion by the first machine or determining the second task for completion by the first machine. The method may also include sending, to an electronic device associated with the operator of the first machine, information about the first route or the second route; and receiving confirmation information indicative of the first machine traversing along the first route or of the first machine traversing along the second route.
More specifically, FIG. 1 schematically illustrates that the computing system 128 may include an alertness determination component 130. In examples described herein, the alertness determination component 130 may analyze sensor data and/or additional information to characterize an alertness of a machine operator. For example, and as described in more detail with regard to FIGS. 2 and 3, the alertness determination component 130 may determine an alertness metric for an operator based on sensor data, e.g., camera data, taken of the operator while the operator is in the cabin of the vehicle. In other examples, the sensor data may be received from a device associated with the operator, which may be a wearable device in some instances. Additional data that may be considered can include information about the operator, e.g., work history, experience level, route history, or the like, and/or information about the machine(s), e.g., wear information, maintenance history, or the like.
