Research has shown that people with direct experience of flooding also tend to feel more at risk and take more preparedness actions. One explanation for this increase in concern is that such direct experience decreases the psychological distance of the hazard, making it more tangible and concrete by relating it to one's immediate physical environment. However, research in this area has not considered whether mediated experience delivered through augmented reality visualizations of local storm surge flooding can similarly affect risk perceptions and preparedness, or how these effects may differ from those of using a more traditional web map of flooding. Accordingly, I report results from a series of user studies exploring how risk perceptions and preparedness vary with the perspective presented by the map or AR tool and individual differences in tool users. Studies were conducted with students on the Texas A&M Galveston campus; in addition to using random assignment to consider the effects of map or AR tool-views, multiple trials with variation in symbol size and users’ physical environment allow for consideration of these factors as possible moderating variables.
