Cognitive Aspects of Interaction in Virtual and Augmented Reality Systems (CAIVARS 2020)

The CAIVARS20 Tutorial is organized with ISMAR2020

The tutorial will analyze interaction in Virtual and Augmented Reality (VR/AR) systems under different points of view. Manuela Chessa, an expert in perceptual aspects of human-computer interaction, will discuss how interaction in AR affects our senses, and how misperception issues negatively affect interaction. Several technological solutions to interact in VR and AR will be discussed and, finally, the challenges and opportunities of mixed reality (MR) systems will be analyzed. Fabio Solarii, an expert in biologically inspired computer vision, will focus on foveated visual perception for action tasks and on the calibration and the geometry of interactive AR. Guido Maiello, an innovative young neuroscientist, will present the link between our eyes and hands in the real world with the aim of improving the design of better interaction techniques in VR and AR. Giovanni Maria Farinella, a leading computer vision expert, will discuss first person vision and egocentric perception. Dimitri Ognibene, whose research uniquely combines robotics with computational neuroscience and machine learning, will describe how perception is an active process in both human and machines. David Rudrauf, a leading expert in mathematical psychology, will present a computational model to investigate human consciousness in virtual worlds. Overall, this unique panel of multi-disciplinary researchers will delineate a compelling argument in favor of investigating human cognition and perception in the context of AR/VR.

Her research interests are focused on the development of natural human-machine interfaces based on virtual, augmented and mixed reality, on the perceptual and cognitive aspects of interaction in VR and AR, on the development of bioinspired models, and on the study
of biological and artificial vision systems. She studies the use of novel sensing and 3D tracking technologies and of visualization devices (e.g. 3D monitors and projectors, head-mounted-displays, video see-through and optical see- through devices) to develop natural and ecological interaction systems, always having in mind the human perception.
In particular, she is active in studying misperception issues, visual stress and fatigue that arise by using such systems. She has been the Program Co-chair of the HUCAPP International Conference on Human Computer Interaction Theory and Applications. She has been the chair of the BMVA Technical Meeting – Vision for human-computer interaction and virtual reality systems, the chair of the Special Session Computer VISION for Natural Human Computer Interaction – VISION4HCI 2016, Lecturer of the tutorial Natural Human-Computer-Interaction in Virtual and Augmented Reality, VISIGRAPP 2017, and Lecturer for the tutorial Active Vision and Human Robot Collaboration at ICIAP 2017 and ICVS2019. She organized the first edition of the tutorial CAIVARS at ISMAR2018. She is author of more than 70 papers in international book chapters, journals and conference
proceedings, and co-inventor of 3 patents.

Giovanni Maria Farinella

Giovanni Maria Farinella obtained the degree in Computer Science (egregia cum laude) from the University of Catania, Italy, in 2004. He is Founder Member of the IPLAB Research Group at University of Catania since 2005. He also became an Associate Member of the Computer Vision and Robotics Research Group at University of Cambridge in 2006, and Associate Member of the Italian National Research Council since 2018. He was awarded a Doctor of Philosophy (Computer Vision) from the University of Catania in 2008. He is currently an Associate Professor at the Department of mathematics and Computer Science, University of Catania, Italy. His research interests lie in the fields of Computer Vision, Pattern Recognition and Machine Learning. He is Associate Editor of the international journals IEEE Transactions on Pattern Analysis and Machine Intelligence,
Pattern Recognition – Elsevier and IET Computer Vision. He has been serving as Area Chair for CVPR 2020, ECCV 2020, ICCV 2017/2019, WACV 2019, ICPR 2018. Giovanni Maria Farinella founded (in 2006) and currently directs the International Computer Vision Summer School. He also founded (in 2014) and currently directs the Medical Imaging Summer School. He is member of the European Laboratory for Learning and Intelligent
Systems (ELLIS), Senior Member of the IEEE Computer Society and Scientific Advisor of the NVIDIA AI Technology Centre (NVAITC). He was awarded the PAMI Mark Everingham Prize 2017.

Guido Maiello

Guido Maiello is an early-career researcher at Justus Liebig University Giessen, in Germany. In 2017, Dr Maiello completed a doctoral program in Visual Neuroscience at University College London. During his doctoral studies Dr Maiello held Visiting Researcher positions at Harvard Medical School, Northeastern University, and the University of Genoa. His doctoral work spanned the topics of human depth perception, motor control, virtual
reality technology and clinical vision. The main focus of his research has been to translate findings from basic vision science into meaningful technological and clinical applications. Just three years out of his PhD, Dr Maiello is currently author of 16 papers in peer-reviewed scientific ournals, over 40 abstracts and conference papers in international meetings, and one international patent. He is Academic Editor at the generalist journal PLOS One, serves as reviewer for 15 international journals, and has served as Area Chair for the ACM Symposium on Eye Tracking Research & Applications (ETRA 2019) and Program Committee Member for the International Conference on Human Computer Interaction Theory and Applications (HUCAPP 2020).
