1. A driver vigilance monitor comprising:
- a prompting device for evoking a response from a driver;
a plurality of hand pressure sensors for continuously measuring hand pressure of the driver applied to different portions of a steering wheel of a vehicle and for detecting the driver'"'"'s response, with the plurality of hand pressure sensors providing hand pressure signals conveying a range of hand pressures applied to different portions of the steering wheel;
a sensor for detecting eye movement or driver head position; and
a processor in communication with the prompting device and the hand pressure sensors and the sensor for detecting eye movement or driver head position,the processor cooperating with the hand pressure sensors and the sensor for detecting eye movement or driver head position to obtain driver-specific data,and wherein the processor determines the driver'"'"'s level of alertness by the driver'"'"'s response to the prompting device.

Abstract
The present invention pertains to a system and method of monitoring the alertness or wakefulness of a driver. The monitored parameters include cardiac, respiratory and movement parameters. Sensors are located in various locations of the driver side section to detect the vigilance of a driver. These sensors include pressure sensors embedded in the seat and pedals, and a head band for monitoring EEG, EMG and EOG signals.

6. A driver vigilance monitor comprising:
-
a prompting device for evoking a response from a driver; a plurality of hand pressure sensors for continuously measuring hand pressure of the driver applied to different portions of a steering wheel of a vehicle and for detecting a driver'"'"'s response, with the plurality of hand pressure sensors providing hand pressure signals conveying a range of hand pressures applied to different portions of the steering wheel; a sensor for detecting eye movement or driver head position; and a processor in communication with the prompting device and the hand pressure sensors and the sensor for detecting eye movement or driver head position, the processor cooperating with the hand pressure sensors and the sensor for detecting eye movement or driver head position to obtain driver-specific data, wherein the processor determines the driver'"'"'s level of alertness by the driver'"'"'s reaction to the prompting device, and further comprising an alert mechanism in communication with the processor and integrated in the vehicle, wherein the alert mechanism is activated by the processor after determining that the driver does not satisfy a vigilance threshold.
