Acceptance criteria
1) Frequency of long glances1) For at least 21 of the 24 test participants, no more than 15 percent (rounded
up) of the total number of eye glances away from the forward road scene have durations of greater than 2.0 seconds while performing the testable task one time.
2) Mean glance duration1) For at least 21 of the 24 test participants, the mean duration of all eye glances
away from the forward road scene is less than or equal to 2.0 seconds while performing the testable task one time.
3) Total glance duration away from the forward roadway1) For at least 21 of the 24 test participants, the sum of the durations of each
individual participant’s eye glances away from the forward road scene is less than or equal to 12.0 seconds while performing the testable task one time.
