Modelling human visual attention is of great importance in the field of computer vision and has been widely explored for 3D imaging. To assess whether model predictions are in alignment with the actual human viewing behavior, ground truth data are required; for this purpose, eye-tracking experiments are typically conducted. In this study , we extend the state-of-the-art by tracking the visual attention of observers in an immersive virtual reality experience with 6 degrees of freedom, using a head mounted display. In this environment, the users interacted with 3D point cloud models following a task-dependent protocol and their gaze and head trajectories were recorded. The logged information was processed and fixation density maps for the models under inspection were obtained.
In this dataset, we make publicly available the tracked behavioural data, post-processing results, saliency maps in form of importance weights, re-distribution of a sub-set of contents and scripts to generate the exact versions of the point clouds that were used in the study, and usage examples.
