Collaborative Data Experiences: Novel designs for visualizing and exploring data together

We are witnessing an unprecedented exponential growth in the data that we create and that we are exposed to in our daily lives. This trend towards “Big Data” promises novel applications that could revolutionize business, administration, policy making, and science. To let users experience and make sense of this data, there is already a lot of research on the algorithmic side, e.g., new methods for data mining, machine learning, etc. There is, however, much less work on how to visually communicate and present results in an “intuitive” and interactive manner, especially to groups of casual or non-expert users.

I will show different examples from my research work that demonstrate how the careful design of interaction and visualization techniques can substantially improve our human-data interaction with visualisations, for example by enabling groups of users to collaborate using visual-tangible user interfaces on interactive tabletops or by working seamlessly across many mobile devices in “bring your own device scenarios”. I will illustrate how a combination of applied informatics, design, and user research can help us to better understand how humans interact with data and achieve a much improved collaborative human-data experience.


Hans-Christian Jetter is a computer scientist and Professor of User Experience and Interaction Design at the University of Applied Sciences Upper Austria, Campus Hagenberg. Before joining Hagenberg, Christian worked as a post doc with Yvonne Rogers at the University College London in the Intel Collaborative Research Institute for Sustainable Connected Cities. Christian also worked as research intern and research visitor at Microsoft Research Cambridge where he explored the use of novel collaborative tools for scientists of the NanoPhotonics Centre of the University of Cambridge. He received his PhD (summa cum laude) and M.Sc. & B.Sc. in Information Engineering from Harald Reiterer at the Human-Computer Interaction Group of the University of Konstanz.
