Table 1: _Cont._Marker-based tracking is often less effective in natural settings, where moving elements and sunlight interference hinder performance [86]. Moreover, AR tools frequently focus on visualization overactive co-creation of public spaces, limiting their utility in placemaking. Inclusivity remains another major concern, with barriers such as digital literacy, device accessibility, and technological complexity marginalizing underrepresented voices in participatory processes, for an example the Urban Co Builder AR tool [80]. Privacy concerns and dependency on high-quality data further complicate AR implementation [64]. To fully harness AR's potential, several key challenges must be addressed. Enhancing accessibility through affordable, intuitive solutions compatible with common devices and resolving connectivity issues is essential for real-time collaboration.
