"A Survey of Recent Advances in 3D Visual Attention for Robotics";
International Journal of Robotics Research, 36 (2017), 11; S. 1159 - 1176.

3D visual attention plays an important role both in human and robotics perception that yet has to be explored in full
detail. However, the majority of computer vision and robotics methods are concerned only with 2D visual attention. This
survey presents findings and approaches that cover 3D visual attention both in human and robot vision, summarising
the last 30 years of research and also looking beyond computational methods. In the first part we present work in
fields such as biological vision and neurophysiology studying 3D attention in humans. This serves to get a view on
the role attention plays at the system level for biological vision. In the second part we cover computer and robot vision
approaches that take into account 3D visual attention. We compare approaches with respect to different categories,
such at feature-based, data-based or depth-based visual attention, and draw conclusions on what advances will help
robotics to better cope with complex real world settings and tasks.
