# CityBuildAR: Enhancing Community Engagement in Placemaking Through Mobile Augmented Reality
## 2 Literature Background
### M-AR as a Participatory Tool
In-Citu AR allows users to visualize urban proposals in real time, improving communication between planners and residents, though it relies on accurate mapping data and faces accessibilitychallenges. The CitySense App provides real-time data visualization on urban metrics such as air quality and traffic, fostering greater awareness but risking information overload and limited user comprehension [61]. The ARPP engages the public in the planning process by enabling interactive participation in urban design, enhancing transparency, but is resource-intensive and may face challenges related to digital literacy and device access [62]. Urban Sketcher encourages community creativity in urban design, promoting collaboration, though it may lack the professional tools necessary for detailed planning [63]. Wikitude overlays data on real-world environments, enriching public understanding of urban spaces, yet its reliance on accurate data and potential privacy concerns may limit its effectiveness [64]. \begin{table}
