Cities are places of communication; where, communication is facilitated and whose streets, infrastructures and structures communicate. An increasing number of technologies enable information from the digital world to be layered onto the physical world potentially altering the person/environment relationship by creating spaces in which users interact with their physical surroundings through digital media. . Location-aware technology makes it possible to simultaneously locate oneself and be networked within city spaces. Mobile phones, GPS receivers, and RFID tags are examples of location-aware mobile technologies that mediate our interactions and influence how we experience and move in these spaces. Privacy and surveillance issues proliferate. Urban space is being redefined and reconceptualized with the addition of mobile gaming, locative social media; and the acceleration of “intelligent” infrastructures. New mapping technologies have introduced VGI (volunteered geographic information) thereby empowering ordinary citizens to collect and distribute geographic information via GPS and Internet mapping resources.The city, as an economic, social, and iconic symbol has been and continues to be under scrutiny by economists, geographers, sociologists, urbanisms, planners and environmental psychologists. There is a growing body of scholarship examining human behavior in urban, suburban, and rural environments from communication perspectives. Health initiatives, urban conflict, race, ethnicity diversity, crisis communication, branding performance in urban spaces, regulation, and mobility studies have all been the lens through which the urban landscape has been examined. The goal of this symposium is to bring together scholars and professionals across disciplines to explore how communication issues contribute to understanding the challenges facing the urban human-environment relationship.
