FIELD CALIBRATION OF AN AUGMENTED REALITY DEVICE

Original Abstract Submitted
a method for recalibrating an augmented reality (ar) device includes generating and storing a ground truth map of a real-world environment when the ar device is operating with a high likelihood of having an accurate factory calibration. during operation of the ar device, new map data is generated for the real-world environment. the new map data is compared to the ground truth map to detect potential calibration errors. if calibration errors are detected, a recalibration procedure is executed by determining an optimal path through the real-world environment that allows for observing parameters requiring recalibration. visual cues are generated to guide a user of the ar device through the optimal path. as the user follows the visual cues, calibration parameters are iteratively adjusted to eliminate detected calibration errors. the recalibration procedure may be presented as an interactive game to improve user engagement, with rewards provided for accurately following guidance.
