Abstract

A pair of artificial-reality glasses that comprise a deformable frame, a rigid unibody member (distinct from the deformable frame and configured to couple to the deformable frame), a first lens assembly (coupled to a first portion of the rigid unibody member) and a second lens assembly (coupled to a second portion of the rigid unibody member at a predefined relative position to the first lens assembly), depth sensors, force sensors, and processors. A nose bridge portion of the rigid unibody member includes structure reinforcements. The force sensors detect deformation of the rigid unibody member such that the second lens assembly is not at the predefined position relative to the first lens assembly. The processors receive deformation data from the one or more force sensors and cause the artificial-reality glasses to apply a disparity correction to the first lens assembly and the second lens assembly.

receive deformation data from the one or more force sensors; and
in accordance with a determination, based on the deformation data, that an amount of disparity between the first lens assembly and the second lens assembly satisfies calibration criteria:
cause the artificial-reality glasses to apply, based on the amount of disparity, a disparity correction to the first lens assembly and the second lens assembly.

2 . The artificial-reality glasses of claim 1 , wherein the determination that the amount of disparity between the first lens assembly and the second lens assembly satisfies the calibration criteria, includes:
comparing deformation data from the one or more force sensors with a default amount of disparity between the first lens assembly and the second lens assembly.

3 . The artificial-reality glasses of claim 1 , wherein the one or more processors coupled with the deformable frame are further configured to:
