    Abstract: An apparatus and method for determining drowsiness of a driver are provided. The apparatus includes an imaging device that obtains an image of the driver and a controller that determines (e.g., based on the image of the driver) when the driver is in a fatigue state, when the driver is in an eyelid closure state, and when the driver is in a wake-up state. The controller further determines that the driver is in a drowsiness state when after the fatigue state of the driver continues over a predetermined first time interval, the eyelid closure state and the wake-up state of the driver alternately and repetitively occur within a predetermined second time interval.

    Abstract: A system for determining a drowsy state of a driver includes: a heartbeat measurement module configured to detect a heartbeat rate of the driver and output a heartbeat signal corresponding to the detected heartbeat rate; a vehicle signal measurement module configured to measure a driving state of a vehicle being driven by the driver and output a vehicle signal corresponding to the measured driving state; a drowsy pattern detection module configured to determine whether a driver has fallen asleep while driving based on the heartbeat signal and the vehicle signal and output a warning signal as a drowsy warning in response to determining that the driver has fallen asleep while driving; and a warning module configured to output a warning to the driver based on the warning signal.

    Abstract: A driver customizable blind spot display method and apparatus are provided. The method of displaying blind spots of a vehicle via a screen mounted within a vehicle includes receiving information regarding positions of the driver's eyes from a driver state monitoring system and receiving current mirror setting information on a per in-vehicle mirror basis from a mirror drive unit. Blind spots and viewable spots are then calculated using the information regarding positions of the driver's eyes and the current mirror setting information. Further, a current blind spot coverage screen is output that displays the calculated blind spots and viewable spots.
