Patent ID: 8199018

Claim:
A human condition detecting apparatus comprising: first stimulus applying means for applying a first stimulus for acquisition of reference information to a driver; second stimulus applying means for applying a second stimulus for acquisition of condition information to the driver; stimulus reaction detecting means for detecting reactions of the driver to the first stimulus applied by the first stimulus applying means as a reference information by an electro dermal activity of the driver and for detecting reactions of the driver to the second stimulus applied by the second stimulus applying means as a condition information by the electro dermal activity of the driver; an event determining means for determining whether a traffic-related event will occur within a predetermined time, the first stimulus applying means applying the first stimulus for acquisition of the reference information to the driver immediately prior to the traffic-related event, and the second stimulus applying means applying the second stimulus for acquisition of the condition information to the driver during the traffic-related event; and condition determining means for determining a condition of the driver, based on a comparison between the reference information and the condition information, wherein the first stimulus applied by the first stimulus applying means is applied multiple times at a predetermined interval and one reference information is obtained from the reactions of the driver to the first stimulus applied multiple times, and the first stimulus applying means applies the first stimulus prior to the traffic-related event every time the event determining means determines that the traffic-related event will occur.
