This article is about assessing whether eye-tracking technology is feasible as a tool for evaluating external HMI technology, which is a topic that will gain importance once autonomous vehicles become ubiquitous. For this end, research about external HMI concepts was done. Based on this research, two main set-ups of external HMI were identified. First consists of placing some form of signaling device (LED strips, light panels, etc.) on the front of the vehicle (upper part of the windshield or the grill). The second one is based on projecting the information on the road between vehicle and pedestrian. Experiment was carried out, simulating a pedestrian looking for external HMI clues whether to cross the street at unsignalized crosswalks. For the experiment, Tobii Pro Glasses II were used for detecting scene in front of the participant and their eye movement and fixation. The aim of the experiment was to ascertain whether the eye-tracker is usable in this kind of experiment, and if so, in what conditions. It was found out that for low traffic and certain weather conditions, eye-tracker can be used to distinguish a single vehicle from about 50 meters and finer elements can be distinguished from about 25 meters, which should be sufficient for external HMI evaluation.
