RingoVision ARON-3 is the augmented reality infrastructure layer that projects digital content directly into BCI users' visual perception. The system overlays digital information onto the user's natural vision in real time — navigation markers, product information, social data, advertising, and interactive interfaces all appear as though they exist in physical space. The technology does not use screens or projectors; it works directly through the BCI's neural interface, adding visual data to the brain's visual processing stream before conscious perception occurs.

The ARON-3 infrastructure consists of spatial anchoring beacons installed throughout GLMZ's physical environment — small devices that broadcast precise location data allowing the BCI to align digital overlays with physical space accurately to within 1 millimeter. Ringo has installed approximately 2 million anchoring beacons across the city, embedded in buildings, street furniture, vehicles, and infrastructure. The beacons are powered by ambient RF energy harvested from the NeuralMesh's transmissions, requiring no dedicated power supply and no maintenance.

The AR overlay is on by default for all BCI users. The baseline overlay includes navigation assistance, emergency information, and — inevitably — advertising. Users can customize their overlay through Ringo's interface, but the advertising layer cannot be disabled without a premium subscription costing 100 Φ per month. The standard ad load is approximately 40 visual interruptions per hour — product highlights on store fronts, branded navigation markers, sponsored information overlays that replace neutral data with promotional content. The overlay has become so integrated with daily perception that many users report difficulty navigating unfamiliar areas with it disabled — they have lost the ability to read physical signage because they have never needed to.
