I’m currently working on an application for mobile where the user is asked to move their phone up and down to match various heights in sequence.
The problem occurs when tracking is momentarily lost and found again and the AR-Camera transform position no longer seems to correspond with the same real world phone height as before.
The tracking is (not unexpectedly) lost when moving the phone very quickly but even during slower movements or with no movement the tracking is lost and the AR-Camera transform “returns” in a different position.
It happens more frequently on lower end devices (Samsung Galaxy S7) and less on higher end (Samsung Galaxy S10e) suggesting that hardware is a limiting factor.
Is there information on specific hardware requirements for devices to track position reliably or if not what are some common bottlenecks for tracking in AR?
