Rapid technological developments have enabled simultaneous existence in the physical & cyberspace and restructured daily life dynamics. Accordingly, new needs for urban systems have emerged, and the use of technology in urban space has increased for different purposes. In that sense, the networked mechanism positioned in public spaces such as urban screens, interactive dashboards, media facades, and cyber-physical systems has begun to revive socio-spatial dynamics, support functional engagement, or collect data from the city. However, there is relatively limited research and practice on how these devices can contribute to participatory planning and design processes, especially in Turkey. Within the scope of the research, the potential and limits of the situated devices in the urban space and related implementations to contribute to participatory processes are examined. In this context, relevant literature and different practices in various countries have been reviewed, and a polling prototype is situated in an urban green space in Beşiktaş (Istanbul, Turkey) to understand the local reflections. The prototype has simple yes/no questions about green space and a QR directing to the online survey for deep feedback. As a result of the research, it has been determined through relevant literature that low-cost technologies added to the elements in urban space can support citizen feedback within limitations; also, in micro case, security issues and user-based data manipulation rendered the data unreliable, so different kind of practices must be tested for better performance and measures should be taken to prevent this situation. Furthermore, situated poll devices can also have micro-effects on spatial mobility and trigger people's follow-up interactions and actions, as seen both in the literature and this case. The prototype's location, size, and way of attracting users are highlighted as critical issues, and it is detected that approaches requiring additional devices are relatively less preferred, security issues may prevent the long-term positioning of devices, and data manipulation issues can affect the accuracy of results.
