Multiuser Collaborative Viewport via Temporal Psychovisual Modulation [Applications Corner]

Consider a multiuser visualization scenario. When making or evaluating emergency response plans for a large city, professionals from police, fire, civil defense, health, environment, transportation, and social services departments meet and discuss. As emergency management involves coordinated activities of various stakeholders, all participants desire to have visual representation of location-sensitive data on a common, integrated display. Separate displays for different types of data cause semantic fragmentation; as one's eyes switch between displays to associate related information, mental transformation in cognitive psychology has to take place, reducing an individual's performance on the task. Moreover, separate personal displays create a feeling of isolation from others and hinders face-to-face communication.
