Abstract (in Japanese) (See Japanese page) 
(in English) This paper describes a method for detecting if a driver can drive safely by measuring pupillary light reflex to active photic stimulus before he/she starts driving. First, we conducted some experiments on drunk and sober drivers, and confirmed that our index “63% dilation time” is effective to classify those drivers. Similarly, we confirmed that another index “half constriction time” is effective to classify sleepy and non-sleepy drivers. As the latter index is completely different from the previous one, our method may be able to discriminate drunk and sleepy drivers independently.
