  • Patent number: 9117358
    Abstract: The present invention generally relates to a method for improving the reliability of a portion of physiological data from an image sensor monitoring an operator positioned in an operator compartment of a vehicle. An embodiment of the method includes receiving, from the image sensor, physiological data including information relating to at least one of eye, face, head, arms and body motion of the operator, identifying an indication of at least an eyelid closure, eye movement or head movement of the operator based on the physiological data; comparing at least one of the physiological data and a lighting condition within the operator compartment with a set of rules for a current operator status; and classifying the type of eyelid closure, eye movement and/or head movement by correlating the identified eyelid closure, eye movement and/or head movement and a result of the comparison.

  • Patent number: 9101313
    Abstract: System for improving a performance estimation of an operator of a vehicle, comprising a first module implementing a first method for estimating a performance state of vehicle operation, a second module implementing a second method for estimating at least one of a physiological and behavioral state of the operator, a device for sharing an estimated state between one of the first and the second module and the other one of the first and the second module, wherein the implemented estimation method of one of the first and the second module is adjusted based on the state of the other one of the first and the second module, thereby improving the estimation of at least one of the performance state of vehicle operation and the physiological and/or behavioral state of the operator.
