A trigger button is positioned on the main body and a handle extends from the main body on a side opposite the trigger button, wherein the handle has a palm side and a finger side. A third-finger button is positioned on the finger side of the handle and includes a magnet mounted thereon. A sensor operative to detect the magnet is positioned inside the handle adjacent the magnet.

Abstract: A virtual-reality system includes a head-mounted display, a camera protruding from a surface of the head-mounted display, and a compressible shock mount mounting the camera to the head-mounted display. The shock mount is to retract the camera towards the head-mounted display when compressed. The shock mount protects the camera from damage when the head-mounted display is dropped.

Abstract: An earbud assembly with separate, flexible overmold sections configured to cover a seam between adjacent portions of an underling earbud housing. The earbud assembly includes a first housing member and a second housing member attached to the first housing member and forming enclosure with the first housing member that houses an audio transducer. A first flexible overmold is formed on an first exterior surface of the first housing member, and a second flexible overmold is formed on an exterior surface of the second housing member. The flexible overmolds each include an edge portion along their perimeters. Each edge portion is configured to abut the other and thereby cover the seam of the earbud housing.

Abstract: A head mounted display (HMD) includes one or more light field cameras for tracking one or both eyes of a user wearing the HMD. The HMD optionally includes light sources positioned inside the HMD and that illuminate one or both of the eyes of the user. The light field camera captures a plenoptic image of the user's eye. The plenoptic image includes light intensity data and direction data of the captured light rays. An eye tracking system updates a 3D light field model of the user's eye based on depth information from the plenoptic image frame. The eye tracking system identifies an iris plane of the user's eye using the 3D light field model. The eye tracking system determines a gaze direction of the user's eye by identifying the normal to the center of the iris plane.

Abstract: A HMD includes a display block. The display block combines light from a local area with image light to form an augmented scene. The display block also provides the augmented scene to an eyebox corresponding a location of a user's eye. The display block includes a waveguide display, a focusing assembly and a compensation assembly. The waveguide display emits the image light. The focusing assembly includes a focusing geometric phase lens and presents the augmented scene at a focal distance. The compensation assembly includes a compensation geometric phase lens that has an axis of orientation orthogonal to an axis of orientation of the focusing geometric phase lens. The compensation assembly compensates the optical power of the focusing assembly.

Abstract: A head mounted display (HMD) comprises an eye tracking system configured to enable eye-tracking using light. The eye tracking system comprises two or more illumination sources positioned relative to one another and an optical detector in order to capture. The optical detector is configured to capture images of the cornea based on one or more reflections. The eye tracking unit is configured to generate a model of the user's eye. The generated eye model is used to determine eye tracking information such as gaze direction as the user glances at different objects in the HMD.

Abstract: A virtual reality (VR) headset includes a first camera and a second camera capturing image data of an environment of the VR headset. Each camera has a field of view, and a portion of the fields of view of the first and second cameras overlap while a portion of the fields of view do not overlap. A processor receiving the image data from the first and second cameras is configured to identify a first observation of a position of the VR headset in the environment and positions of a plurality of features based on the image data captured by the first camera. The processor also identifies a second observation of the position of the VR headset in the environment and the positions of the features based on the image data captured by the second camera. Based on the first and second observations, the processor determines a model of the environment.

Abstract: A virtual reality system enables a user to interact with virtual objects. The system includes a fiducial ring, an imaging device and a console. The fiducial ring includes a ring body that includes a plurality of fiducial markers that each correspond to a different location on the ring body. An imaging device is configured to capture one or more images of the fiducial ring. The console receives the images that include an image of one or more fiducial markers. Based on the received images of the fiducial markers, the console determines a location on the fiducial ring that corresponds to the imaged fiducial marker. The console determines a position of the fiducial ring based on the determined location of the fiducial marker on the fiducial ring. The console provides content to a head mounted display (HMD) based on the determined position of the fiducial ring.

Abstract: A headset for virtual reality applications includes an optical element configured to modify light from an electronic display in the headset and to direct the modified light to a user. The optical element may include a Fresnel lens secured to a lens by securing the Fresnel lens to a mold and inserting a casting material into the mold so the casting material forms the lens and a portion of the casting material exists on and past an edge of the Fresnel lens. This encases the edge of the Fresnel lens in the casting material, securing the Fresnel lens to the lens.

Abstract: A head-mounted display system includes a left lens for a user's left eye and a right lens for the user's right eye. The head-mounted display system also includes left and right display screens. The left display screen is coupled to the left lens to provide images to the user's left eye through the left lens. The right display screen is coupled to the right lens to provide images to the user's right eye through the right lens.

Abstract: Embodiments relate to a strap system having a securing plate and a strap. The securing plate is configured to be secured to a body of a head-mounted display in a rotatable manner. The securing plate includes a flat portion, a rear loop located at a first end of the flat portion, and a front loop located at a second end of the flat portion. The strap is inserted through the rear loop and the front loop of the securing plate. An end portion of the strap is flipped over the front loop and secured to a portion of the strap on the flat potion of the securing plate to fix the strap to the securing plate.
