Open Google Maps. Before you take the first step, which direction are you facing? You don't know. Neither does your phone. The compass in your phone is wrong more often than it's right. Outdoors, it's a minor annoyance — you take a step, GPS corrects itself, and you're fine. But the scenario indoors is a disaster. For example: You're a passenger stepping off a flight into an unfamiliar terminal. You open the airport app, it says turn left, but "left" according to your phone might actually be behind you. You start walking the wrong way. Now the blue dot is chasing you instead of guiding you. The indoor positioning industry spent a decade trying to answer, "where am I?" The harder question was always, "which way am I facing?" This is why visual positioning matters more than most people realize. One camera frame and the model will recognize where you are and your direction. Your compass is corrected before you take your first step. Set someone down the right path initially and you've solved half of the wayfinding problem. – By the way, this is something Mappedin now solves for with the Start from Here feature, just shipped: ordnl.link/Kji3d61
