| Popis | With mobile eye trackers becoming widely available, cognitive scientists are exploring the possibilities of getting more hard data in the world outside of the laboratories, enhancing the ecological validity of their research. These eye trackers are easy to use and practical to wear, as they are almost wireless. Their sampling frequency is incomparable to the remote eye trackers, but for the types of tasks that are usually executed outside, it's sufficient. Nevertheless, some argue that the attractivity of portable eye trackers might be overrated (Hessels et al., 2020). Lately, it became obvious that there are many challenges regarding outdoor eye tracking data collection and analysis (Evans et al., 2019). The most important question is how precise the measurement in the terrain really is. The volatile light conditions (Binaee et al., 2021), bumps and shakes of the glasses (Niehorster et al., 2020) and change of the viewing angle through the walk need to be taken into consideration during experimental preparation. With the extensive amount of manual work needed for data analysis it might seem that in the end the work behind correct use of mobile eye trackers might not be worth it. But there is a modern solution that can at least partly help by transferring research to the virtual world. Research shows that from cognitive point of view iVR (immersive virtual reality) is a suitable substitution for the real world in the context of spatial orientation research (Dong et al., 2021; Drewes et al., 2021; Stachoň et al., 2022), which might open a whole new approach to measuring eye tracking data during wayfinding. Unfortunately, the available options of eye tracking measurement in iVRs poses a completely new challenge for data collection and analysis, as most of the commercially available HMDs (head mounted displays) with integrated ET are not suitable for serious research. Knowing exactly what kind of eye behaviour is happening is crucial for correct data interpretation, but most newer HMDs have integrated self-made ET, which works as an absolute black box to users and furthermore have no possibility to export any of the ET al., 2023). These HMDs are thus hardly if ever usable for research. Some of the commercial headsets (e.g., Pico, PS) have ET provided by Tobii, who lets you, for a generous fee, export raw data apart from the basic heatmap available. Currently many scientists are trying to program their own eye trackers. |
