Three-dimensional integrated circuit component(s) are described including a System-on-a-Chip (SoC) die and a separate static random-access memory (SRAM) subcomponent in a vertically stacked arrangement. Such stacked SoC/SRAM integrated circuit components may form part of a system to render artificial reality images.

Illumination devices as include a frame intended to be worn by a user and one or more light sources (e.g., LEDs) positioned by the frame so as to be near a user's zygomatic bones and oriented to project light in a direction of the user's view when the illumination device is worn on the wearer's head. The frame may be shaped to be worn over the user's ears and behind the user's head, and may be made of one or more of plastic, metal and/or a metal alloy, carbon fiber, wood, cellulose acetate, natural horn and/or bone, leather, and an epoxy resin. An optional strap may be retractably attached to connect portions of the frame over the wearer's head. The LEDs may be included in respective panels swivelly mounted to booms of the frame and the panels may further include imaging devices, such as a camera, and/or a projector.

An apparatus having an asymmetric adjustable lens with a deformable optical element. The apparatus may also include one or more actuators coupled to a deformable element of the asymmetric adjustable lens in a direct-drive configuration such that (1) mechanical action of the one or more actuators applies force to the deformable optical element and (2) the force applied by the mechanical action of the one or more actuators changes an optical property of the asymmetric adjustable lens by deforming the deformable optical element. Various other devices, systems, and methods are also disclosed.

Disclosed is a head mounted electronic device including a body, a lens clip having at least one opening defined therein, wherein the lens clip is disposed on the body so as to face toward a face of a user, an infrared-ray emissive device disposed on one portion of the body, an infrared-ray imaging device disposed on an opposite portion of the body to one portion thereof, wherein the infrared-ray imaging device acquires a first eyeball image obtained when infrared-ray emitting from the infrared-ray emissive device is reflected from an eyeball of the user, and a processor operatively connected to the infrared-ray emissive device and the infrared-ray imaging device.

A system, method, and computer-readable medium are disclosed for performing clamping force adjustment on a virtual reality (VR) headset. User preferences as to clamping force at one or more positions, such as rest position on top of the user's head and VR mode position on user's face, are determined. The preferences are stored in a user profile. When a user places the VR headset, clamping force at a position is measures and clamping force is adjusted at that position.

An extended reality headset is configured to position and stabilize the headset on a face when worn. For example, the headset can include an external frame with first and second side pieces coupled to a display structure and configured to provide lateral stabilization. In some examples, the headset can include a front head-engaging structure front head-engaging structure that is rotationally coupled to the external frame via a pivot point. The headset can also include a rear head-engaging structure coupled the external frame. In some examples, the rear head-engaging structure can include a tensioning mechanism to adjust the headset to fit various head shapes. Additionally, the headset can include a flexible strap coupled to the front head-engaging structure and the tensioning mechanism. In some examples, applying tension to the flexible strap by the tensioning mechanism can cause the front head-engaging structure to rotate along the pivot point, providing a secure fit.

A wearable display device includes a mounting unit, an image display unit that displays an image, a frame that supports the image display unit, an imaging unit that is supported by the frame and that captures an external scene, a coupling unit that connects the frame and the mounting unit such that a position of the image display unit with respect to the mounting unit is changeable in a first direction, and an image acquisition unit that acquires a first image of the external scene from a range on one side in the first direction in an imaging range of the imaging unit when the position of the image display unit with respect to the mounting unit is changed from the one side to another side in the first direction.

An apparatus including a set of three illumination sources disposed in a first plane. Each of the set of three illumination sources is disposed at a position in the first plane offset from others of the set of three illumination sources by 120 degrees measured in polar coordinates. The apparatus also includes a set of three waveguide layers disposed adjacent the set of three illumination sources. Each of the set of three waveguide layers includes an incoupling diffractive element disposed at a lateral position offset by 180 degrees from a corresponding illumination source of the set of three illumination sources.

A wearable display device including a mounting unit, an image display unit that displays an image, a frame that supports the image display unit; an imaging unit that is supported by the frame and that captures an external scene, a coupling unit that connects the frame and the mounting unit in a manner that a position of the image display unit with respect to the mounting unit changes from one side to another side in a first direction, and a driving unit that changes an angle of the imaging unit to tilt the imaging unit toward the one side in the first direction when the position of the image display unit is changed from the one side to the other side in the first direction.

The technology disclosed relates to a method of realistic rendering of a real object as a virtual object in a virtual space using an offset in the position of the hand in a three-dimensional (3D) sensory space. An offset between expected positions of the eye(s) of a wearer of a head mounted device and a sensor attached to the head mounted device for sensing a position of at least one hand in a three-dimensional (3D) sensory space is determined. A position of the hand in the three-dimensional (3D) sensory space can be sensed using a sensor. The sensed position of the hand can be transformed by the offset into a re-rendered position of the hand as would appear to the wearer of the head mounted device if the wearer were looking at the actual hand. The re-rendered hand can be depicted to the wearer of the head mounted device.
