This talk will give an overview of three research initiatives that use VR technology. First, a series of studies that used large screen pedestrian and bicycling simulators to examine how two people coordinate their decisions and actions when crossing a stream of traffic. The studies reveal the powerful influence that others have on how we make consequential decisions in performing routine but potentially dangerous activities. Second, a series of studies looking at how mobile technology can help pedestrians to safely cross traffic-filled roadways. And last, an experiment in using VR to create immersive theatrical experiences.
