CampusWatch: Exploring Communitysourced Patrolling with Pervasive Mobile Technology

Community policing to collaboratively maintain community safety and order in conjunction with law enforcement is becoming increasingly popular and efficient with the use of mobile technologies. Beyond sharing information about local problems such as crime via online discussion forums, there has been an increased focus on the impact of mobile, location-based systems on community policing. In this study, we designed a novel communitysourced patrolling campaign in which community members schedule their own patrol times and routes, then perform location-based patrolling with video capturing and sharing using their smartphones. We conducted a four-week field study (n=20) on a university campus to verify the campaign's feasibility and observe users' behavior. Our results show key findings about users' task scheduling, event capturing and reporting behaviors, factors affecting task selection and execution, and user motivation and engagement. Finally, we discuss several practical design implications in building location-based systems for communitysourced patrolling.
