Various other detachable head-mounted-display strap-interface apparatus, devices, 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.

A conventional head-mounted display may include a strap system that holds the head-mounted display on a user’s head and against the user’s face. Unfortunately, the straps or other components of a conventional strap system may become worn and dirty over time, which may necessitate removal and replacement of the straps. Additionally, conventional head-mounted displays are often shipped with generic one-size-fits-all strap systems that may not suit every user. For example, generic one-size-fits-all strap systems may not fit all users equally well and may not suit the stylistic tastes of many users, especially users that have a more individualized fashion sense. For at least these reasons, many users may want or need to remove and replace the generic one-size-fits-all strap systems that come with conventional head-mounted displays.

SUMMARY 

As will be described in greater detail below, the instant disclosure generally relates to detachable head-mounted-display strap interfaces, devices, systems, and methods. In some embodiments, a detachable head-mounted-display strap-interface apparatus may include (1) a strap that includes an electrical accessory that necessitates an electrical connection to a head-mounted display and (2) a mount coupled to the strap that includes (a) an interface that is mateable and demateable to an opposing interface of the head-mounted display, (b) an electrical connector that is configured to provide the electrical connection from the electrical accessory to the head-mounted display when contacting an opposing electrical connector of the head-mounted display, and (c) a latch that couples, in a first orientation, the interface and the opposing interface of the head-mounted display and enables, in a second orientation, the interface to be decoupled from the opposing interface of the head-mounted display and the electrical connector to be disconnected from the opposing electrical connector. The latch may couple, in the first orientation, the interface and the opposing interface of the head-mounted display such that the electrical connector and the opposing electrical connector maintain contact and the strap holds the head-mounted display against a user’s face.

In some embodiments, the opposing interface of the head-mounted display may include a mateable and demateable plug, the interface may include a receptacle that is configured to receive the plug of the head-mounted display, and the latch may be configured to (1) retain, in the first orientation, the plug of the head-mounted display in the receptacle and (2) enable, in the second orientation, the plug of the head-mounted display to be decoupled from the receptacle and the electrical connector to be disconnected from the opposing electrical connector. In some examples, the receptacle may include a planar base, and the electrical connector may be integral to the planar base. In at least one example, the electrical connector may be further recessed into the planar base.

In some embodiments, the mount may include four additional electrical connectors that are configured to provide additional electrical connections to the head-mounted display when contacting four additional opposing electrical connectors of the head-mounted display. In some embodiments, the opposing electrical connector may include a spring connector, and the electrical connector may include a contact pad configured to blind-mate (i.e., self align) to the spring connector. In some examples, the electrical connector may be configured to carry electrical power, an audio signal, a video signal, a sensor signal, or a control signal, and the electrical accessory may include a motion-tracking accessory (e.g., a light-emitting motion-tracking accessory), an audio accessory, or a cable.
