TY - JOUR PY - 1996// TI - Method of detecting drowsiness level by utilizing blinking duration JO - JSAE review A1 - Sugiyama, K. A1 - Nakano, T. A1 - Yamamoto, S.

We have developed a system which measures the blinking duration of a driver by processing his facial image and estimates his drowsiness level. This paper presents an imaging unit which is less affected by ambient light, a method of measuring the driver's blinking duration which is independent of his facial features, and a method of estimating his drowsiness level from a change in his blinking duration.
