Space Topology Change Mostly Attracts Human Attention: An Implicit Feedback VR Driving System.

Driving safety, especially for autonomous vehicles, is severely challenged by unexpected object motions. To investigate the internal mechanism of how human vision can instantly and robustly respond to those sudden changes, a novel implicit feedback VR driving system is designed. Wherein, the object-level and space-level topological properties for scene changes are introduced, and the simulated driving scenes are constructed in VR environment with EEG signals and eye-tracking feedback. The experimental results demonstrate that, space-level topology changes mostly attract human visual attention among the space-level, object-level and non-topology changes. Obviously, the results inform a very solid theoretical foundation for developing safer assisted even autonomous driving systems.
