An eyewear device with flexible frame for Augmented Reality (AR) is disclosed. At least two sensors and a display are mounted on the flexible frame. When in use, the real time geometry of the eyewear device may change from factory calibrated geometry, resulting in low quality AR rendering. A modeling module is provided to model the real time geometry of the eyewear device on the fly using sensor information of the at least two sensors. The modeled real time geometry is then provided to a rendering module to accurately display the AR to the user.

An exemplary extended reality presentation system determines that a depiction of an augmentable object within a field of view takes up a first portion of the field of view, and, in response to this determination, presents a first form of an overlay object within the field of view. The first form of the overlay object is graphically associated with the augmentable object. During the presenting of the first form of the overlay object within the field of view, the system determines that the depiction of the augmentable object has come to take up a second portion of the field of view, and, in response to this determination, replaces the first form of the overlay object with a second form of the overlay object within the field of view. The second form of the overlay object is distinct from the first form. Corresponding methods and systems are also disclosed.
