Members of the SFB TRR 161 have recently participated in an “Workshop on Crowdsourcing” at the University of Konstanz. The organizers, Franz Hahn and Vlad Hosu, introduced the use of CrowdFlower for quantitative user-studies. The intention was to get participants familiar with the platform and the basic concepts of crowdsourcing for user studies. All participants were able to design and run their own hands-on experiment, to get a better feel of the challenges and benefits of crowdsourcing.
We are currently running an online study in the field of graph visualization. We hypothesize an optimum in the ratio of node size and edge width in node-link-diagrams. This study is wrapped in two online games, which are based on such node-link-diagrams. Here, we still need more played games. You do not need to have special knowledge about Graph Theory or similar, you only need to operate your mouse.
Nowadays, we increasingly deal with navigation systems to find our way to unknown places, or have a look at digital maps or street views to get a first impression of places we have never been before. As the computational hardware and software conditions are constantly improving, the applications and their underlying building models do with increasing geometric complexity and detailed textures. But by creating new systems that use virtual city models, we always have to keep one question in mind: What kind of representations do we really need to understand the inherent information? Within our research we want to get a deeper understanding of the human’s cognitive experience of virtual 3D cities.
