- 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.
- 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.
