Results of Radial vs. Cartesian Experiment

In this research we conducted two user experiments. First, we tried an online evaluation with originally more than 1,000 people trying to find out if colored objects in a Cartesian or a radial counterpart representation can be remembered better and if the corresponding tasks can be answered faster. In a second scenario, we conducted a controlled experiment with only a few participants and a smaller number of tasks.
