Description
This paper describes unconstrained method to monitor driver's biological signal during driving without phyical constraint. also, this study shows the feasibility for evaluation of driver's health and stress state.
Abstract
Nonintrusive monitoring of a driver’s physiological signals was
introduced and evaluated in a car as a test of extending the
concept of ubiquitous healthcare to vehicles. Electrocardiogram,
photoplethysmogram, galvanic skin response, and respiration
were measured in the ubiquitous healthcare car (U-car) using
nonintrusively installed sensors on the steering wheel, driver’s
seat, and seat belt. Measured signals were transmitted to the
embedded computer via Bluetooth® communication and processed.
We collected and analyzed physiological signals during driving in
order to estimate a driver’s stress state while using this system.
In order to compare the effect of stress on physical and mental
conditions, two categories of stresses were defined. Experimental
results show that a driver’s physiological signals were measured
with acceptable quality for analysis without interrupting driving,
and they were changed meaningfully due to elicited stress. This
nonintrusive monitoring can be used to evaluate a driver’s state of
health and stress.
