Abstract

The electro-oculogram (EOG) is widely used in the laboratory for measuring eye movements but seldom in the field. Some disadvantages of the EOG for measuring gaze behavior (for example lack of stability) can be overcome by using on-line computer identification of saccades and additional keyboard marking of relevant gazes by the experimenter. This uncovers the advantages of the EOG measuring precise fixation durations of gazes on defined instruments, activation decrements and increments of the driver due to time on task or mental effort (via saccadic velocity), and blink behavior as controlled interruptions of visual behavior. Three related studies of traffic relevant questions are examined for measuring the usefulness of the EOG-on-line measuring device.
