• Collective Intelligence in Online Groups

    Collective Intelligence is the general problem solving performance of a team that emerges beyond the abilities of the individuals. Previous studies had shown that this ability is driven by empathy (or more correctly theory-of-mind abilities). But those studies were done with face to face groups. We did a study to see if this also holds true for online groups.

  • Medial Feature Superpixels

    Pixels are the basis of most modern image representations and the starting point of most computer vision algorithms. However, they are actually just artefacts of the image capture and display process. They do not correspond to entities in the real world. Enter superpixels. Superpixels are groupings of pixels into homogeneous regions. They are not yet semantic segmentations of images but reduce the complexity of an image by merging continuous regions into mid-level representations.

  • Detectability of pedestrians

    You’re likely not going to run over a pedestrian that you’ve noticed. So, the pedestrians that are most in danger are the ones you didn’t see. The ones that blend into the background or are just in unexpected places. A driving assistance system should draw your attention to these kinds of pedestrians to ensure you make the right decisions. During my PhD at the Max Planck Institute I did a study combining experimental psychology and computer vision to predict which pedestrians are hard to notice and model where your attention should be direct to maximize the likelihood that you’re going to notice all pedestrians in a scene.

  • Exploring an inifinite maze in VR

    One of the more fun studies I did during the beginning of my PhD. We had a tracking hall that allowed free natural movement in VR. It was big but still limited. But, if you introduce small, consistent errors during the movement you can trick the VR users to walk in circles while and make your tracking space functionally infinite.

  • Integrated information and are groups consious?

    Do groups posess consciousness? It might seem an interesting question from a philosophical point of view but how do we approach this question from a scientific angle?
