The key to awake elderly people's emotional engagement in an artificial companion is its emotional behavior. Therefore, we propose a companion that does not look(More)
Contemporary video games are highly complex systems with many interacting variables. To make sure that a game provides a satisfying experience, a meaningful analysis of gameplay data is crucial, particularly because the quality of a game directly relates to the experience a user gains from playing it. Automatic instrumentation techniques are increasingly(More)
Instrumentation to automatically log information – so called gameplay metrics – about the player-game interaction has become an important tool for analyzing player behavior in games. However, due to the usually large amount of gathered data, analysis of the collected data can be challenging. Visualizations have become a promising addition to statistical(More)
This paper describes an implementation of a progressive radiosity algorithm for triangular meshes which works completely on programmable graphics processors. Errors due to the rasterization of triangles are fixed in a post-processing step or with a fragment shader during runtime. Adaptive subdivision to increase the accuracy of the radiosity solution can be(More)
