Hand tracking enables more direct, embodied interaction in virtual reality (VR), yet its practical value for creating urban and landscape design interventions remains under-examined. This paper presents a VR simulator that enables users to explore a site and propose spatial interventions through hand-tracking interaction, transforming design into an embodied act of spatial exploration and making. A pilot user study (N=5) examined the simulator’s usability and user experience. Results suggest that hand tracking supports the full interaction and provides practical advantages during immersive design activity. This paper contributes a hand-tracking-enabled VR interaction approach and derives design implications for accessible urban and landscape design with lay participants.
