Facial-interface systems for head-mounted displays
A detachable head-mounted-display cushion may include a cushion layer having a user-side surface dimensioned to abut a facial portion of a user and a display-side surface dimensioned to abut a mounting surface of a facial-interface system for a head-mounted display. The detachable head-mounted-display cushion may also include a magnetic-coupling mechanism configured to removably attach the cushion layer to the mounting surface of the facial-interface system. A corresponding head-mounted-display system may include a head-mounted display, a facial-interface mounting member for the head-mounted display, a cushion layer abutting the facial-interface mounting member, and a magnetic-coupling mechanism removably attaching the cushion layer to the facial-interface mounting member. A method may include positioning a cushion layer abutting a facial-interface mounting member for a head-mounted display and removably attaching the cushion layer to the facial-interface mounting member with a magnetic-coupling mechanism. Various other head-mounted-display cushions, head-mounted-display systems, and methods are also disclosed.

a magnetic-coupling mechanism configured to removably attach the cushion layer to the mounting surface of the facial-interface systems;
wherein:
the cushion layer defines a plurality of display-side recesses that are separate from the viewing opening; and
each of the plurality of display-side recesses extends into the cushion layer from the display-side surface toward the user-side surface and is dimensioned to receive a corresponding mounting protrusion protruding from the mounting surface at an outer region of the facial-interface system.
2. The detachable head-mounted-display cushion of claim 1 , wherein the cushion layer defines a user-side recess extending into the cushion layer from the user-side surface toward an adjacent display-side recess of the plurality of display-side recesses, the user-side recess being separated from the adjacent display-side recess by an inner section of the cushion layer.
3. The detachable head-mounted-display cushion of claim 2 , wherein the user-side recess overlaps the adjacent display-side recess in a direction extending between the user-side surface and the display-side surface.
4. The detachable head-mounted-display cushion of claim 2 , wherein:
the inner section of the cushion layer comprises:
a display-side-recess end surface defining an end portion of the adjacent display-side recess closest to the user-side recess; and
a user-side-recess end surface defining an end portion of the user-side recess located closest to the adjacent display-side recess; and
the display-side-recess end surface is substantially parallel to the user-side-recess end surface.
5. The detachable head-mounted-display cushion of claim 1 , wherein the magnetic-coupling mechanism comprises at least one magnetic coupling element.
6. The detachable head-mounted-display cushion of claim 5 , wherein the magnetic coupling element is disposed within at least one user-side recess extending into the cushion layer from the user-side surface.
7. The detachable head-mounted-display cushion of claim 1 , wherein the cushion layer comprises a foam material.
8. The detachable head-mounted-display cushion of claim 1 , wherein:
the cushion layer further defines a plurality of user-side recesses; and
each of the plurality of user-side recesses overlaps an adjacent display-side recess and extends into the cushion layer from the user-side surface toward the adjacent display-side recess.
9. A head-mounted-display system comprising:
a head-mounted display;
a facial-interface mounting member for the head-mounted display;
a cushion layer abutting the facial-interface mounting member, the cushion layer comprising:
an inner surface surrounding a viewing opening;
a user-side surface dimensioned to abut a facial portion of a user; and
a display-side surface abutting the facial-interface mounting member; and
a magnetic-coupling mechanism removably attaching the cushion layer to the facial-interface mounting member;
wherein:
the cushion layer defines a plurality of display-side recesses that are separate from the viewing opening; and
each of the plurality of display-side recesses extends into the cushion layer from the display-side surface toward the user-side surface and surrounds a corresponding mounting protrusion protruding from an outer region of the facial-interface mounting member.
10. The head-mounted-display system of claim 9 , wherein the display-side surface abuts a mounting surface of the facial-interface mounting member.
11. The head-mounted-display system of claim 9 , wherein:
the cushion layer defines a user-side recess extending into the cushion layer from the user-side surface; and
the magnetic-coupling mechanism comprises a magnetic coupling element disposed within the user-side recess.
12. The head-mounted-display system of claim 9 , wherein:
the facial-interface mounting member comprises at least one mounting-member magnetic element;
the magnetic-coupling mechanism comprises at least one magnetic coupling element; and
the cushion layer is removably attached to the facial-interface mounting member by a magnetic field between the magnetic coupling element and the mounting-member magnetic element.
13. The head-mounted-display system of claim 12 , wherein at least a portion of the cushion layer is disposed between the mounting-member magnetic element and the magnetic coupling element.
14. A method comprising:
positioning a cushion layer abutting a facial-interface mounting member for a head-mounted display, the cushion layer comprising:
an inner surface surrounding a viewing opening;
a user-side surface dimensioned to abut a facial portion of a user; and
a display-side surface dimensioned to abut the facial-interface mounting member; and
removably attaching the cushion layer to the facial-interface mounting member with a magnetic-coupling mechanism;
wherein:
the cushion layer defines a plurality of display-side recesses that are separate from the viewing opening; and
each of the plurality of display-side recesses extends into the cushion layer from the display-side surface toward the user-side surface and surrounds a corresponding mounting protrusion protruding from an outer region of the facial-interface mounting member when the cushion layer is positioned abutting the facial-interface mounting member.
15. The method of claim 14 , wherein removably attaching the cushion layer to the facial-interface mounting member with the magnetic-coupling mechanism comprises positioning the cushion layer between at least one magnetic coupling element of the magnetic-coupling mechanism and at least one mounting-member magnetic element of the facial-interface mounting member.
16. The method of claim 14 , wherein positioning the cushion layer abutting the facial-interface mounting member comprises conforming the cushion layer to a mounting surface of the facial-interface mounting member.
