Human-Computer Interaction technology (HCI) is a research area concerned with the design, implementation, and evaluation of interactive systems that make more simple and intuitive the interaction between user and computer. This book contains the contributions to the 6th International Conference on Augmented Reality, Virtual Reality and Computer Graphics (SALENTO AVR 2019) that has held in Santa Maria al Bagno (Lecce, Italy) during June 24–27, 2019. Orga- nized by the Augmented and Virtual Reality Laboratory at the University of Salento, SALENTO AVR 2019 intended to bring together the community of researchers and scientists in order to discuss key issues, approaches, ideas, open problems, innovative applications, and trends in virtual and augmented reality, 3D visualization, and com- putergraphicsintheareasofmedicine,culturalheritage,arts,education,entertainment, military, and industrial applications. We cordially invite you to visit the SALENTO AVR website (www.salentoavr.it) where you can find all relevant infor- mation about this event. We are very grateful to the Program Committee and Local Organizing Committee members for their support and for the time spent to review and discuss the submitted papers and for doing so in a timely and professional manner.
