Schematic of the Experimental Setup (IMAGE) University of Konstanz Caption Schematic of the experimental setup: Depending on whether the coated glass beads have many or few neighbors within their field of vision (red), they are either illuminated by a laser beam or not. Researchers can use such an experiment to investigate the effects of visual information on the collective behavior and swarming of swimming microparticles.
