Human beings need to be empowered to access, explore, analyze, and make sense of data and information everywhere in our data-driven world. Interactive data visualization on mobile devices has been established as one important means to support this need. In general, the past decade has seen an increasing research interest in visualization environments beyond traditional desktop computers, and visualization on mobile devices will play a prominent role in a future of diversified visualization environments.

In this talk, we will discuss the role that mobile devices can play beyond using them for single visualizations by a single person, which is currently the predominant use for, e.g., health and other personal data visualization. Based on the discussion of several own research examples, it will be shown a) how smartphones and smartwatches can be used in multi-device ensembles including large displays and multiple mobiles, b) how mobile devices can be brought closer to the body as personal visualization hubs and how new form factors can be envisioned beyond the rigid and flat high-resolution displays we are currently using, and c) how mobile devices can be combined with mixed reality technologies to allow for even more convincing, reality-based in-situ visualizations. During the talk, we will also outline research challenges associated with each of these research directions.

Bio:

Raimund Dachselt is a full professor of Computer Science and head of the Interactive Media Lab at Technische Universität Dresden, one of Germany’s Universities of Excellence. His research interests encompass natural human computer interaction (HCI), interactive information visualization, and Mixed Reality interaction. He worked extensively in the area of interactive surfaces from smartwatches over tablets and tabletops to wall-sized displays (also combined in multi-display environments) and combined interaction modalities (e.g., multi-touch and pen, tangible displays, gaze-supported interaction, body gestures). He and his team made pioneering contributions to the field of interactive data visualization beyond the desktop including solutions for mobile devices, ultra-large displays, multi-device environments, Augmented Reality and other Immersive Analytics approaches. Significant contributions in the area of physical computing have recently extended the technology spectrum beyond commonly available devices.

Prof. Dachselt received his PhD in 2004 from TU Dresden and was professor for User Interface & Software Engineering at University of Magdeburg from 2007 to 2012. At the Faculty of Computer Science at TU Dresden he has been elected director of the Institute of Software and Multimedia Technology, and served as vice-dean from 2016-2018. He has published more than 230 peer-reviewed publications, co-authored two major German textbooks on HCI and received more than a dozen Best Paper, Honorable Mention and further publication awards at leading international HCI and visualization conferences.

Dachselt is a member of several computer societies, has co-organized 16 international workshops at ACM and IEEE conferences, and is the steering committee chair of ACM ISS. He repeatedly served as a co-chair (general, program, doctoral symposium, demo, publicity, keynote chair) and PC member for top international HCI conferences and was guest editor of several special journal issues. Between 2010 and 2013 he also served as the European coordinator of the EU-funded transatlantic exchange project LEIF with eight Canadian and European Universities. Since 2019 he is the Dresden spokesperson of the Transregional Collaborative Research Center (SFB/TR 248) Center for Perspicuous Computing (CPEC).
