With increasing realism of computer graphics and virtual worlds and digital characters look more and more natural. However, the effect of Uncanny Valley, first described in 1970, prevents too realistic human characters from being accepted. In my Ph.D. thesis, I investigate how the Uncanny Valley affects the user experience in virtual environments and virtual reality and how the effect can be avoided.
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.
