A driver may not be aware that they are in danger due to fatigue. A
driver might feel they must continue driving. Our driver fatigue alarm
system reminds the driver that he/she is in a dangerous state. The
EA401 uses a PERCLOS algorithm to analyze the driver's fatigue level.
The state of the driver's eyes is constantly analyzed. The human retina
reflects infra-red light in a manner that can be used to determine the
eye's condition. This varies just prior to falling asleep. The EA401
knows you are falling asleep before you close your eyes.
If the EA401 determines the driver is in a dangerous state a sharp
voice will alert the driver.
