Despite the fact that virtual environments are increasingly deployed to study the relation between urban planning, physical and social disorder, and fear of crime, their ecological validity for this type of research has not been established. This study compares the effects of similar signs of public disorder (litter, warning signs, cameras, signs of vandalism and car burglary) in an urban neighborhood and in its virtual counterpart on the subjective perception of safety and livability of the neighborhood. Participants made a walking tour through either the real or the virtual neighborhood, which was either in an orderly (baseline) state or adorned with numerous signs of public disorder. During their tour they reported the signs of disorder they noticed and the degree to which each of these affected their emotional state and feelings of personal safety. After finishing their tour they appraised the perceived safety and livability of the environment. Both in the real and in the simulated urban neighborhood, signs of disorder evoked associations with social disorder. In all conditions, neglected greenery was spontaneously reported as a sign of disorder. Disorder did not inspire concern for personal safety in reality and in the virtual environment with a realistic soundscape. However, in the absence of sound disorder compromised perceived personal safety in the virtual environment. Signs of disorder were associated with negative emotions more frequently in the virtual environment than in its real-world counterpart, particularly in the absence of sound. Also, signs of disorder degraded the perceived livability of the virtual, but not of the real neighborhood. Hence, it appears that people focus more on details in a virtual environment than in reality. We conclude that both a correction for this focusing effect and realistic soundscapes are required to make virtual environments an appropriate medium for both etiological (e.g. the effects of signs of disorder on fear of crime) and intervention (e.g. CPTED) research.
The goal of this article is two-fold: to introduce the concept of augmented deliberation and to demonstrate its implementation in a pilot project.We look specifically at a project called Hub2. This community engagement project employed the online virtual world Second Life to augment community deliberation in the planning of a neighborhood park in Boston, Massachusetts. The local community was invited to gather in a physical space and a virtual space simultaneously, and a physical moderator and virtual designer orchestrated deliberation.This project demonstrates the design values central to augmented deliberation: (1) it is a multimedia group communication process which balances the specific affordances of digital technologies with the established qualities of face-to-face group deliberation; (2) it emphasizes the power of experience; and (3) it promotes sustainability and reproducibility through digital tracking. Augmented deliberation, when properly designed, provides a powerful mechanism to enable productive and meaningful public deliberation. The article concludes with directions for further research.
