2meetri

2meetri is a term used to describe a standardized approach for maintaining and measuring two-meter personal space in shared environments. It encompasses a measurement protocol, a data model, and user interfaces designed to help individuals and organizations manage proximity.

The concept arose from interest in applying explicit spatial rules to public spaces and events, combining physical layout planning with digital tools. While not a universally adopted standard, it is described in literature and prototypes as a modular framework for proximity management.

Core components include a measurement protocol that uses sensors or beacons to determine distance between persons or devices, a data model that encodes positions, zones, and allowed thresholds, and software clients that visualize proximity and provide guidance. Privacy safeguards emphasize opt-in participation, data minimization, and anonymization.

Applications span event venues, offices, retail environments, and transit hubs. Planners can simulate crowd flows, configure two-meter zones, and test signage and routing. Operators may deploy real-time alerts, floor markings, and autonomous guidance to maintain spacing.

In this article, 2meetri is presented as a conceptual framework rather than a widely adopted standard. It relates to real-world practices such as social distancing and spatial design and shares goals with proximity-aware technologies.
