“…For individual AOIs, the iMotions software (https://imotions.com/) was used to calculate the quantitative eye movement indexes. These indexes were calculated for all persons taking part in a given test on the basis of registered fixations mapped automatically on the reference image [69] within the selected AOI. The following indexes were selected for analysis (iMotions Help Center, version 7.1, December 2018):…”

“…Mapping was conducted using the image processing methods of image feature detection and description algorithms that were used to determine the position of subsequent video frames and to map the corresponding gaze coordinates on a common reference image. This process allowed for the aggregation of our results for further experimental analysis, as well as providing an alternative for manual semantic gaze mapping methods [69].…”

A landscape is part of our daily lives and our perception of its features may significantly impact our quality of life. This article presents the results of research aimed at determining the influence of biometeorological conditions on the way in which we perceive the landscape. An eye tracker was used throughout each season of the year to determine how 52 respondents observed the landscape while taking into consideration whether the landscape had a favorable or unfavorable impact on those same respondents. Additionally, each test was preceded by the completion of a questionnaire intended to assess the mental and physical state of each respondent. The calculated eye movement indexes demonstrated the impact of the biometeorological conditions on their perception of the landscape. Statistically significant differences in their perception of the landscape were ascertained depending on the type of weather and the respondents’ general feeling irrespective of their sex.

“…A widespread approach in eye tracking is the estimate of the user's visual axis, by use of a calibrated system and mapping the detected pupil to a scene. Whether an object has been examined in the scene is often determined by an assignment of fixation points using fixed boundaries around an object or region of interest (Bykowski & Kupiński, 2018;MacInnes, Iqbal, Pearson, & Johnson, 2018).…”

Combining advanced gaze tracking systems with the latest vehicle environment sensors opens up new fields of applications for driver assistance. Gaze tracking enables researchers to determine the location of a fixation, and under consideration of the visual saliency of the scene, to predict visual perception of objects. The perceptual limits, for stimulus identification, found in literature have mostly been determined in laboratory conditions using isolated stimuli, with a fixed gaze point, on a single screen with limited coverage of the field of view. The found limits are usually reported as hard limits. Such commonly used limits are therefore not applicable to settings with a wide field of view, natural viewing behavior and multi-stimuli. As handling of sudden, potentially critical driving maneuvers heavily relies on peripheral vision, the peripheral limits for feature perception need to be included in the determined perceptual limits. To analyze the human visual perception of different, simultaneously occurring, object changes (shape, color, movement) we conducted a study with 50 participants, in a driving simulator and we propose a novel way to determine perceptual limits, which is more applicable to driving scenarios.

“…To find out what a participant is looking at and being able to compare the gaze data of several different participants, a common reference, on which every single fixation can be mapped, is required (Bykowski & Kupiński, 2018). An example of the mapping process is shown in Figure 1.…”

MAP3D: An explorative approach for automatic mapping of real-world eye-tracking data on a virtual 3D model

Mobile eye tracking helps to investigate real-world settings, in which participants can move freely. This enhances the studies’ ecological validity but poses challenges for the analysis. Often, the 3D stimulus is reduced to a 2D image (reference view) and the fixations are manually mapped to this 2D image. This leads to a loss of information about the three-dimensionality of the stimulus. Using several reference images, from different perspectives, poses new problems, in particular concerning the mapping of fixations in the transition areas between two reference views. A newly developed approach (MAP3D) is presented that enables generating a 3D model and automatic mapping of fixations to this virtual 3D model of the stimulus. This avoids problems with the reduction to a 2D reference image and with transitions between images. The x, y and z coordinates of the fixations are available as a point cloud and as .csv output. First exploratory application and evaluation tests are promising: MAP3D offers innovative ways of post-hoc mapping fixation data on 3D stimuli with open-source software and thus provides cost-efficient new avenues for research.
