The rigid support frame element may be shaped and configured to physically support a display of a head-mounted display system in front of a user's eyes when the facial interface assembly is worn by the user. The flexible facial interface frame element may be configured to flex to conform to the user's facial features when the facial interface assembly is worn by the user. An outer periphery of the flexible facial interface frame element may be independently movable relative to an outer periphery of the rigid support frame element. Various other systems and methods are also disclosed. ## Claims ### Claim 1 A facial interface assembly for a head-mounted display system, comprising: a rigid support frame element dimensioned to physically support a display of the head-mounted display system; and a flexible facial interface frame element configured to interface with a face of a user, wherein: the flexible facial interface frame element comprises at least one rigid support element that couples the flexible facial interface frame element to the rigid support frame element, the at least one rigid support element is positioned in a laterally central region of the flexible facial interface frame element, the flexible facial interface frame element comprises a laterally outer peripheral region, laterally outside of the at least one rigid support element, the laterally outer peripheral region of the flexible facial interface frame element is configured to independently flex relative to a laterally outer peripheral region of the rigid support frame element, and includes a part configured to conform to the user's facial features located between an eye of the user and an ear of the user, and at least a portion of the part configured to conform to the user's facial features located between the eye of the user and the ear of the user is decoupled from the rigid support frame element. ### Claim 2 (depends on 1) The facial interface assembly of claim 1, wherein a first rigid support element of the at least one rigid support element provides a standoff between the rigid support frame element and the flexible facial interface frame element. ### Claim 3 (depends on 1) The facial interface assembly of claim 1, wherein the laterally outer peripheral region lacks any rigid support element between the laterally outer peripheral region of the flexible facial interface frame element and the laterally outer peripheral region of the rigid support frame element. ### Claim 4 (depends on 1) The facial interface assembly of claim 1, wherein the at least one rigid support element comprises a first upper rigid support element. ### Claim 5 (depends on 1) The facial interface assembly of claim 1, wherein the at least one rigid support element comprises a first lower rigid support element. ### Claim 6 (depends on 5) The facial interface assembly of claim 5, wherein the at least one rigid support element comprises a second lower rigid support element different from the first lower rigid support element. ### Claim 7 (depends on 1) The facial interface assembly of claim 1, further comprising: an extensible material disposed between the rigid support frame element and the flexible facial interface frame element. ### Claim 8 (depends on 7) The facial interface assembly of claim 7, wherein the extensible material comprises a flexible fabric material. ### Claim 9 (depends on 8) The facial interface assembly of claim 8, wherein the flexible fabric material comprises a woven fabric material. ### Claim 10 (depends on 8) The facial interface assembly of claim 8, wherein the flexible fabric material comprises a breathable fabric material. ### Claim 11 (depends on 7) The facial interface assembly of claim 7, wherein the extensible material is configured to block at least some external visible light from reaching a user's eyes when the head-mounted display system is worn by the user. ### Claim 12 (depends on 1) The facial interface assembly of claim 1, further comprising: a facial interface padding coupled to a surface of the flexible facial interface frame element. ### Claim 13 (depends on 12) The facial interface assembly of claim 12, wherein the facial interface padding is configured to contact a user's face when the head-mounted display system is worn by the user. ### Claim 14 (depends on 12) The facial interface assembly of claim 12, wherein the facial interface padding comprises foam. ### Claim 15 (depends on 14) The facial interface assembly of claim 14, wherein the facial interface padding comprises foam is covered by a fabric material. ### Claim 16 (depends on 1) The facial interface assembly of claim 1, wherein the rigid support frame element comprises a bump for removably coupling the display to the rigid support frame element. ### Claim 17 (depends on 1) The facial interface assembly of claim 1, wherein the rigid support frame element is configured to removably couple to the display using a magnet. ### Claim 18 (depends on 1) The facial interface assembly of claim 1, wherein the flexible facial interface frame element comprises a nasal bridge portion configured to accommodate such different nose shapes and sizes for a comfortable fit on a variety of different users when the head-mounted display system is worn by the different users. ### Claim 19 (depends on 1) The facial interface assembly of claim 1, wherein the flexible facial interface frame element is configured to flex to conform to the user's facial features when the head-mounted display system is worn by the user. ### Claim 20 (depends on 19) The facial interface assembly of claim 19, wherein the head-mounted display system comprises a head strap, and the flexible facial interface frame element is configured to flex based on an application of a force applied by the head strap.
