Abstract: A strap system for a head-mounted display system includes a rigid bar, semi-rigid segment, and rigid segment. The rigid bar includes a lateral slot and a vertical slot. The rigid segment includes a first end to fixedly couple to the semi-rigid segment and a second end opposite to the first end. The second end of the rigid segment inserts into the lateral slot from the first end of the rigid bar. The strap system further includes one or more compression springs coupled to the rigid segment, and a shuttle to press against the one or more compressions spring so as to slide along the lateral dimension. The strap system also includes an adjustment strap fixedly coupled to the shuttle and extending beyond the second end of the rigid segment and through the vertical slot on the rigid bar to adjustably couple to the outer surface of the rigid bar.

Abstract: A head-mounted display includes a first display screen and a second display screen to display images to respective eyes of a user. The head-mounted display further includes a first member comprising a first rack and a second member comprising a second rack. The first member is coupled to the first display screen, and the second member is coupled to the second display screen. The head-mounted display includes a button and a gear train to transfer a linear sliding motion of the button to a linear motion of the first rack in a first direction and a linear motion of the second rack in a second direction opposite to the first direction. The gear train includes a first gear engaged with the first rack and a second gear concurrently engaged with the first gear and the second rack.

Abstract: A strap system for a head-mounted display is disclosed. The strap system includes a rigid segment and a latching subsystem coupled to the rigid segment. The rigid segment has opposite first and second sides. The rigid segment couples to the head-mounted display from the first side. The latching subsystem couples to the second side of the rigid segment. The latching subsystem includes a plate including a pair of slots to respectively receive a pair of posts protruding from a detachable audio system. The latching subsystem also includes a pair of latches to latch to grooves in the pair of posts. Each latch of the pair of latches includes an opening that overlaps a respective slot of the pair of slots. The opening receives a respective post of the pair of posts.

Abstract: A virtual-reality system includes a head-mounted display, a camera mounted on and protruding from a surface of the head-mounted display, and a compressible shock mount mounting the camera on the surface. 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: A head-mounted display for a virtual-reality system includes one or more outer surfaces having a plurality of recesses. Light-emitting diodes (LEDs) are installed in respective recesses of the plurality of recesses. The recesses are covered with covers that are substantially flush with respective surfaces of the one or more outer surfaces of the head-mounted display.

Abstract: A strap system and a method for wearing the strap system are disclosed. The strap system includes a first flexible segment comprising a first stretchable band; a first semi-rigid segment to conform to a portion of the user's head and comprising a first arc portion to extend from above a user's first ear to below the user's occipital lobe; and a first rigid guide segment connected to the first flexible segment and the first semi-rigid segment. The first flexible segment extends beyond a first end of the first rigid guide segment and the first semi-rigid segment extends from a second end of the first rigid guide segment, the first and second ends of the first rigid guide segment being opposite to each other in a lateral dimension. The first flexible segment is stretchable within the first rigid guide segment along the lateral dimension.

Abstract: A virtual reality (VR) console receives slow calibration data from an imaging device and fast calibration data from an inertial measurement unit on a VR headset including a front and a rear rigid body. The slow calibration data includes an image where only the locators on the rear rigid body are visible. An observed position is determined from the slow calibration data and a predicted position is determined from the fast calibration data. If a difference between the observed position and the predicted position is greater than a threshold value, the predicted position is adjusted by a temporary offset until the difference is less than the threshold value. The temporary offset is removed by re-calibrating the rear rigid body to the front rigid body once locators on both the front and rear rigid body are visible in an image in the slow calibration data.
