ARway's accuracy meter is a real-time location accuracy indicator displayed during a map experience. It uses custom algorithms to determine drift and displays a dial from 10 to 1. The dial will show a perfect score of 10, a declining accuracy score of 5, a recommendation to rescan at a score of 3, and a requirement to rescan at a score of 1. The accuracy meter also provides additional details and directs users to the nearest access point if they need to rescan.
