Visualization, virtual reality and reproducibility: Challenges and opportunities
Arzu Çöltekin is a professor of computer science in human-computer interaction (HCI) and extended reality (XR) at the Institute of Interactive Technologies of the University of Applied Sciences and Arts Northwestern Switzerland (FHNW). She is also a research affiliate at Harvard University’s Harvard-Smithsonian Center for Astrophysics, Seamless Astronomy group. Her interdisciplinary work covers topics related to information science, visual analytics, visualization and cartography, vision (perception and cognition), eye tracking, gaze-contingent displays, extended (virtual, augmented, mixed) reality, and human-computer interaction. She is an active member of several international organizations, e.g., the ICA (International Cartographic Association), the ISPRS (International Society for Photogrammetry and Remote Sensing) and the ISDE (International Society of Digital Earth). She serves as the co-chair of the Visual Analytics Commission for the ICA, and as the chair of the international working group on Geovisualization, Virtual and Augmented Reality of the ISPRS’ Spatial Information Sciences commission. Furthermore, she serves at the advisory board of the ‘data visualization Zurich’ initiative, digitAS national project in Austria, and is a council member with the International Society of Digital Earth.
Abstract: Earth observation data can be extremely information-rich, including imagery from aerial, satellite and terrestrial sensors, and point-clouds, each further enhanced by attribute data in many cases. Thus, the sheer size and complexity of earth observation data not only presents unique analysis and visualization challenges, but also forces us to think about topics of openness and reproducibility. In this talk we will focus on digital earth projects, with specific empirical experiment examples from visualization and virtual reality perspective, and examine both the replication and reproducibility challenges as well as opportunities within this domain.
