Methods and apparatus for secure persistent location based digital content associated with a two-dimensional reference

This invention describes a system where a person uses a smart device, like a phone, to view digital content that is permanently linked to a specific physical location. The device's software identifies a defined area within a building and displays an interactive icon representing the digital content, which remains tied to that spot regardless of visual changes to the physical space.

Why it matters: Filed before widespread Lidar integration in consumer smart devices made highly accurate, persistent 3D mapping for AR more feasible. The claims for location-based content that persists despite visual changes are now more achievable with current device capabilities.
