    "title": "Motion perception of biological swarms",
    "subtitle": null,
    "abstract": "Biological swarms are collections of many independent\nagents who are motivated to remain clustered in a large group.\nThe motion of swarms, then, is complex, with the influence if\nindependent members within a coherent structure of the\ngroup. We investigated whether human perception of\nbiological swarms was sensitive to this internal complexity of\nthe group motion, as has been observed for biological motion\nof single objects, such as the limbs of a walking person. In\ntwo experiments, we tested motion detection and\ndiscrimination of biological swarm motion compared with\nscrambled, unstructured spiral and rigidly-structured\nrotational motion. The results showed that discrimination of\nswarms was superior to perception of scrambled swarms that\ncontained no structure, but was worse than discrimination of\nthe motion of rigid structures. These results suggest that\nperception of swarms does not engage a specialized\nmechanism for detecting internal structure, as is found with\nother types of biological motion, but instead reflects the\nproperties of perception of a coherent global motion. These\nresults have implications for the design of human-machine\ninterfaces. The majority of existing human-robot swarm\ninteraction visualizations presents the human user with each\nindividual swarm member. The presented results imply that\nan abstract visualization representing the general swarm\nstructure will perform as well, or better than visualizations of\neach individual.",
