Abstract: An artificial-reality headset comprises a first lens assembly coupled with a first shape guide, and a second lens assembly coupled with a second shape guide. The artificial-reality headset comprises an interpupillary-distance (IPD) adjustment system that moves one or both of the first lens assembly and the second lens assembly to produce a first IPD between the first lens assembly and the second lens assembly, and a second IPD between the first lens assembly and the second lens assembly. A membrane is included, and the membrane is in contact with the first and second shape guides such that: when the first IPD is produced between the first lens assembly and the second lens assembly, a number of creases in the portions of the membrane is a first number, and when the second IPD is produced between the first lens assembly and the second lens assembly, no new creases are introduced.

Abstract: As disclosed herein, a bidirectional ratchet for an anti-slippage knob-ratchet to adjust strap length for securing a virtual reality headset onto the head of a user is provided. In one aspect, the bidirectional ratchet may include a first pawl, configured to engage with a stationary ratchet drum in an outer housing to allow movement of a pinion in a clockwise direction. The bidirectional rachet may include a second pawl, configured to engage with the stationary ratchet drum to allow movement of the pinion in a counterclockwise direction. A knob system and a headset are also provided.

Abstract: Aspects of the present disclosure are directed to an adjustment mechanism for adjusting an eye-to-lens distance of a headset display device. The adjustment mechanism can include an adjustment wheel that is rotatable by a user, a pinion gear fixed to a screw, and a threaded member receiving the screw and mounted to a forehead pad frame supporting a forehead pad. The adjustment wheel can include an internal bevel gear ring. The pinion gear is rotated by rotation of the internal bevel gear ring, and the screw rotates with the pinion gear. The pinion gear and the screw can rotate about a second axis. The threaded member moves along the screw, as the screw rotates, to move the forehead pad to adjust the eye-to-lens distance. The internal bevel gear ring, the pinion gear, and the screw are configured to allow additional components to pass through an interior of the adjustment wheel.

Abstract: The disclosed systems for positioning head-mounted displays may include a first track along which a display apparatus of a head-mounted display is configured to move in a first direction and a second track along which the display apparatus is configured to move in a second, different direction. A first electromechanical actuator may move the display apparatus along the first track, and a second electromechanical actuator may move the display apparatus along the second track. Various other methods and systems are also disclosed.

Abstract: Techniques are described herein that are capable of providing selectable interaction elements in a 360-degree video stream. A selectable interaction element is an element (e.g., user interface element) for which selection of the element initiates the providing of information pertaining to an object with which the element is associated. For instance, the selectable interaction element may be positioned proximate the object in the 360-degree video stream (e.g., a portion of the 360-degree video stream or an entirety of the 360-degree video stream). Examples of a user interface element include but are not limited to text, an icon, and a widget.

Abstract: Techniques are described herein that are capable of providing a bowtie view of an environment. A bowtie view of an environment is a representation of a 360-degree image of the environment that is compressed at its center such that at least one side of the bowtie view is concave. For example, two opposing sides of the bowtie view may be concave. In accordance with this example, the two opposing sides may be top and bottom sides of the bowtie view. The 360-degree image is unwrapped to provide a flattened image. The flattened image is projected on an inner surface of a virtual object in a three-dimensional virtual environment. A portion of the flattened image is captured from the inner surface of the virtual object using a virtual camera to provide the bowtie view.

Abstract: Techniques are described herein that are capable of performing action(s) based on automatic participant identification. For example, participants of a meeting may be automatically identified independently from an invitee list for the meeting. In another example, participants of the meeting may be automatically identified even if such participants are not indicated by the invitee list. An action is performed with regard to the participants of the meeting based at least in part on the participants being automatically identified.

Abstract: Techniques are described herein that are capable of providing a polyptych view that includes three or more designated video streams. A polyptych view is a view that includes multiple discrete sections. Each section includes a respective designated video stream. A designated video stream is a video stream of a participant of a video conference who is identified to be a designated participant in the context of the video conference. For example, a participant of a video conference may become a designated participant by speaking for at least a first threshold duration of time during the video conference and/or having a priority greater than or equal to a priority threshold. In another example, a participant may no longer be deemed a designated participant if the participant does not speak for a second threshold duration of time, speaks less than others, and/or has a priority that is less than others.
