Comparison of Five On-Head, Eye-Movement Recording Systems

摘要

The study compared the relative merits of five eye-movement measuring systemswith regard to their applicability for studying drivers' visual behavior. The systems tested were Applied Science Laboratories 210, Applied Science Laboratories 4000 Series, ISCAN Headhunter, NAC Model V, and Ober2. Evaluations were made from laboratory tests on dimensions including accuracy, discomfort (pain and pressure, weight, imbalance, and freedom of movement), view obstruction, safety, and compatibility with the driving task. Consideration was given to the systems usefulness both for on-road and laboratory use. Accuracy was evaluated by recording eye-system data output from a subject following a regimented visual tracking task. The ASL4000 performed best, followed by the ISCAN and the Ober2. Comfort was rated on four parameters by the wearer on a seven-point scale. Overall, the Ober2 rated most comfortable, followed by the ASL 4000. View obstruction was evaluated by mapping the wearer's field of view. Overall, the ISCAN and the ASL4000 restricted field of view the least. The results from the laboratory tests, as well as from the manufacturers' specifications, are summarized.
