Abstract 

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.

BACKGROUND 

Virtual reality head-mounted displays have wide applications in various fields, including engineering design, medical surgery practice, military simulated practice, and video gaming. For example, virtual reality head-mounted displays may allow users to experience realistic, immersive virtual environments while playing video games, during flight simulation training, or when interacting with co-workers around the globe.

Virtual reality head-mounted displays often include cushioned facial-interface systems that enable users to comfortably position the head-mounted displays on their faces. However, the cushioning of facial-interface systems may become worn and dirty over time. Additionally, a particular cushioned facial-interface system may not comfortably fit users of various head or face shapes or users who wear glasses while wearing the head-mounted displays.

SUMMARY 

As will be described in greater detail below, the instant disclosure generally relates to facial-interface systems for head-mounted displays, detachable head-mounted-display cushions, and methods for assembling facial-interface systems. In some embodiments, 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.

In some examples, the cushion layer may define a display-side recess extending into the cushion layer from the display-side surface toward the user-side surface. In addition, the display-side recess may be dimensioned to receive a corresponding mounting protrusion protruding from the mounting surface of the facial-interface system. In one example, the cushion layer may also define a user-side recess extending into the cushion layer from the user-side surface toward the display-side recess. In this example, the user-side recess may be separated from the display-side recess by an inner section of the cushion layer.

In some examples, the user-side recess may overlap the display-side recess in a direction extending between the user-side surface and the display-side surface. In addition, the inner section of the cushion layer may include (a) a display-side-recess end surface defining an end portion of the display-side recess closest to the user-side recess and (b) a user-side-recess end surface defining an end portion of the user-side recess located closest to the display-side recess. In this example, the display-side-recess end surface may be substantially parallel to the user-side-recess end surface.

In some examples, the magnetic-coupling mechanism may include at least one magnetic coupling element. In addition, this magnetic coupling element may be disposed within at least one user-side recess extending into the cushion layer from the user-side surface. In one example, the cushion layer may be formed from a foam material.

In some examples, the cushion layer may define a plurality of display-side recesses and a plurality of user-side recesses. In these examples, each of the plurality of display-side recesses may extend into the cushion layer from the display-side surface. In addition, each of the plurality of user-side recesses may overlap an adjacent display-side recess and extend into the cushion layer from the user-side surface toward the adjacent display-side recess.

A corresponding head-mounted-display system may include a head-mounted display, a facial-interface mounting member for the head-mounted display, and a cushion layer abutting the facial-interface mounting member. The head-mounted-display system may also include a magnetic-coupling mechanism removably attaching the cushion layer to the facial-interface mounting member.

In one example, the cushion layer may include a display-side surface abutting a mounting surface of the facial-interface mounting member. In this example, the cushion layer may define a display-side recess extending into the cushion layer from the display-side surface. In addition, the facial-interface mounting member may include a mounting protrusion disposed within the display-side recess.

In some embodiments, the cushion layer may also include a user-side surface configured to abut a facial portion of a user. In these embodiments, the cushion layer may define a user-side recess extending into the cushion layer from the user-side surface. In addition, the magnetic-coupling mechanism may include a magnetic coupling element disposed within the user-side recess.

In some examples, the facial-interface mounting member may include at least one mounting-member magnetic element and the magnetic-coupling mechanism may include at least one magnetic coupling element. In these examples, the cushion layer may be removably attached to the facial-interface mounting member by a magnetic field between the magnetic coupling element and the mounting-member magnetic element. In addition, at least a portion of the cushion layer may be disposed between the mounting-member magnetic element and the magnetic coupling element.

In one embodiment, a method may include (a) positioning a cushion layer abutting a facial-interface mounting member for a head-mounted display and (b) removably attaching the cushion layer to the facial-interface mounting member with a magnetic-coupling mechanism.

In one example, positioning the cushion layer abutting the facial-interface mounting member may include positioning a mounting protrusion of the facial-interface mounting member within a display-side recess defined within the cushion layer. In this example, the display-side recess may extend into the cushion layer from a display-side surface of the cushion layer facing the facial-interface mounting member.

In some embodiments, removably attaching the cushion layer to the facial-interface mounting member with a magnetic-coupling mechanism may include 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. In addition, positioning the cushion layer abutting the facial-interface mounting member may include conforming the cushion layer to a mounting surface of the facial-interface mounting member.
