The Internet as a low-threshold communication channel provides the possibilities to exchange knowledge, communicate with each other and act outside of the traditional frameworks to nearly everybody around the globe. Therefore, digitalization processes, resulted by diffusion of information and communication technologies, might have massively transformed the contemporary urban settings. The essential elements in this contemporary urban setting are flow of communication and information exchange that are happening through networks. Recently, the widespread of smartphones and tablets with their unique features (e.g. embedded sensors, multi-channel communication, high-speed mobile Internet, intuitive design and portability) have changed the interaction of citizens in and with the urban environment. Furthermore, the new science of cities understands cities as dynamic setting embedded with flows and networks between individual actors and the urban environment, which entails urban planning as a collective process. This indicates that the planning approach has experienced that beside top-down approaches, bottom-up perspective in decision making processes is occurring. Given this fact, today it is no longer the question whether the public should be involved, but rather with which methods a broader spectrum of citizens can cooperate in planning processes. Thus, the participatory methods should be evolved aligned with the new characteristics of the contemporary urban settings and utilize the potentials offered by mobile technologies to enhance the citizen engagement processes in urban planning. Hence, this project’s goal is to investigate a relatively new emerging form of participation as Mobile Participation (mParticipation), which refers to the use of mobile devices (mobile phones, smart phones and tablets) in participation processes. This research, at the first step, endeavors to study the relevance, advantages, disadvantages and specific characteristics of mParticipation. In the next step, the influence of utilizing mobile technologies on communication between different actors, flow of information as well as citizens’ network (as the essential elements in the contemporary urban settings) are studied. Finally, the influence of utilizing mobile technologies (smart phones and tablets) on the output and quality of output is investigated. Doing that, a comprehensive literature review on current debates in digitalization in urban settings (smart cities), citizen engagement in urban planning discourse (collaborative planning) and characteristics of citizen engagement in the age of information and technology (electronic participation mobile participation) has been conducted. In order to investigate the mParticipation from practical aspects and processes, several mParticipation projects from USA as well as Europe are evaluated and field tests (using FlashPoll application) are carried out in Berlin. These analyses are enriched by 15 expert interviews (from USA and Germany). The results of this research project elaborate the potentials, limitations and characteristics of mParticipation in urban planning. In addition, the influences of mParticipation on information flow, communication between stakeholders, the network of citizens and quality of participation outputs are clarified. Although, mParticipation offers new and unique opportunities to urban planning processes, the results of this research shows that there is still room for knowledge generation in this field of study. In addition, the continuous technological advancement in the field of mobile technologies shapes mParticipation field as a dynamic field of research.
