In the domain of access control, the notion of zone is still ambiguous. The zone demands clearer contextualization that resonates with the security operators in their workplace. Through interpretive research, this project aims to investigate intuitive ways to monitor the overview of security through visualisation and propose a groundwork that can facilitate discussion around future possibilities of zones in physical access control. Based on the sense making process, this project presents three visualisation models: textual, physical, and abstract. Each model explores various representations of zones to communicate zone-to-zone relationships to improve usability. Also, the design work demonstrates diverse expressive qualities interacting with spaces that are physical, conceptual, and logical. In the most practical sense, the zone means groups of doors, however, the zone also embodies an abstract layer of interpretation that is not strictly connected to a physical space.
