Lecture | Cross-Device and Transitional Interfaces for Human-Data Interaction

Held by:

Hans-Christian Jetter, Unversity of Lübeck 

Abstract:

In this talk, I will present some of my past work and an outlook on future research on human-data interaction (HDI). I will introduce some of the collaborative and/or cross-device systems that we created in the past to let teams interactively explore, experience, visualize, and make sense of complex data sets and data models. Thereby we have made extensive use of post-desktop devices and form factors, e.g., relying on touch and pen interaction with large screens or multiple connected tablets (see for example Research Group iDUX). In particular, I will present insights from designing, implementing, and evaluating these technologies with respect to cognitive/emotional/behavioral/social aspects. For example, I will discuss our observation of a “legacy bias” that hinders users from adopting novel, powerful, but also unfamiliar technologies. Furthermore, I will describe our current and future research in HDI on transitional interfaces for cross-reality/cross-virtuality analytics that span traditional 2D screens, augmented reality, and virtual reality. Such transitional interfaces will enable users to freely move between different locations within the reality-virtuality continuum during work to let them choose the best technologies for their task at hand and current information need (see for example Workshop at ACM ISS 2021).

Biography:

Hans-Christian Jetter is a computer scientist, Professor of Interaction Design and User Experience, and Head of the iDUX (Interaction Design and User eXperience) group at the University of Lübeck. He is particularly interested in designing human-computer interaction (HCI) and human-data interaction (HDI). His research group designs, implements, and studies novel ubiquitous, mixed-reality, and collaborative technologies for exploring, visualizing, and making sense of complex data sets and models.

Before joining the University of Lübeck in Summer 2020, he was a professor and head of the research group HIVE (Human Interfaces & Virtual Environments) at the University of Applied Sciences Upper Austria from 2015-2020.

In 2013 & 2014, he was a research associate and postdoc at University College London (UCL) in the Intel Collaborative Research Institute on Sustainable Connected Cities (ICRI). Christian also worked as research visitor and intern at Microsoft Research Cambridge in 2009 & 2011. Christian holds a B.Sc. and M.Sc. in Information Engineering from the Human-Computer Interaction Group of the University of Konstanz in Germany where he also received his PhD in Computer Science in 2013.

Lecture | Epistemology of Data Visualization

Held by:

Ali Zolfagharian, Advanced Data and Information Literacy Track, University of Konstanz

Abstract:

Epistemology of Data Visualization (EDV) could be divided into three sub-domains by following questions: (a) When could an agent claim that she understands a data visualization? (non-propositional attitude) (b) When could an agent say I have been informed with a data visualization? (c) What could be the epistemic role of a data visualization in knowledge claim? (Propositional attitude) I start the talk with explaining my findings in ontological study of Data, information, and Data visualization; in order to provide a conceptual framework for the discussion. Then I provide a simple account for every question from normative point of view. At the end, I extend the first question (a) to the understanding of interactive data visualization after explaining why it should be the central question in EDV. 

Biography:

Ali Zolfagharian studied physics (BSc) at Semnan University, Iran and philosophy of science (M.A) at Sharif University of Technology, Iran. He has received his Ph.D in philosophy at the University of Konstanz, and his research area was formal epistemology. Now he is teaching 'Data Philosophy' Course at the University of Konstanz as a member of Advanced Data and Information Literacy Track.
