Abstract
We have been working on a project on "Development of the drive dozing prevention technique using the sensor installed in the seat for detecting the driver's condition" for about five years. As a non-invasive sensor equipped with a drivers' seat for passenger cars, we developed so called "air pack sensor" which is expected to an alternative of finger plethysmogram. In the previous paper, mathematical modeling for air pack sensor was conducted and the method for extracting the heart rate signal from the signal obtained by the air pack sensor was proposed. In this paper, we mainly investigated the relation between the effect of the sensor position and the accuracy.
