Zusammenfassung
Mobile eye tracking studies involve analyzing areas of interest (AOIs) and visual attention to these AOIs to understand how people process visual information. However, accurately annotating the data collected for user studies can be a challenging and time-consuming task. Current approaches for automatically or semi-automatically analyzing head-mounted eye tracking data in mobile eye tracking studies have limitations, including a lack of annotation flexibility or the inability to adapt to specific target domains. To address this problem, we present IMETA, an architecture for semi-automatic fixation-to-AOI mapping. When an annotator assigns an AOI label to a sequence of frames based on the respective fixation points, an interactive video object segmentation method is used to estimate the mask proposal of the AOI. Then, we use the 3D reconstruction of the visual scene created from the eye tracking video to map these AOI masks to 3D. The resulting 3D segmentation of the AOI can be used to suggest labels for the rest of the video, with the suggestions becoming increasingly accurate as more samples are provided by an annotator using interactive machine learning (IML). IMETA has the potential to reduce the annotation workload and speed up the evaluation of mobile eye tracking studies.
