1. A system, comprising:
- an electro-dermal potential sensing system configured to sense electro-dermal potential of a person and configured to output an electro-dermal potential signal, wherein the electro-dermal potential system includes a plurality of contactless sensors configured to be mounted in a vehicle;
at least one physiological sensor configured to measure at least one physiological state of the person and output at least one physiological signal; and
a controller configured to receive the electro-dermal potential signal from the electro-dermal potential sensing system and the at least one physiological signal and to determine a drowsiness state of the person, wherein the controller is configured to adjust operation of a vehicle system using the determined drowsiness state, and wherein the controller is further configured to receive an external sensor signal from a vehicle environmental sensor system configured to sense external objects around a vehicle and to output a control signal using the electro-dermal potential signal, the at least one physiological signal and the external sensor signal to adjust operation of the vehicle environmental sensor system in the vehicle.
