  • Publication number: 20200402316
    Abstract: A method for placing content in an augmented reality system. A notification is received regarding availability of new content to display in the augmented reality system. A confirmation is received that indicates acceptance of the new content. Three dimensional information that describes the physical environment is provided, to an external computing device, to enable the external computing device to be used for selecting an assigned location in the physical environment for the new content. Location information is received, from the external computing device, that indicates the assigned location. A display location on a display system of the augmented reality system at which to display the new content so that the new content appears to the user to be displayed as an overlay at the assigned location in the physical environment is determined, based on the location information. The new content is displayed on the display system at the display location.

  • Patent number: 10861242
    Abstract: Examples of wearable systems and methods can use multiple inputs (e.g., gesture, head pose, eye gaze, voice, totem, and/or environmental factors (e.g., location)) to determine a command that should be executed and objects in the three-dimensional (3D) environment that should be operated on. The wearable system can detect when different inputs converge together, such as when a user seeks to select a virtual object using multiple inputs such as eye gaze, head pose, hand gesture, and totem input. Upon detecting an input convergence, the wearable system can perform a transmodal filtering scheme that leverages the converged inputs to assist in properly interpreting what command the user is providing or what object the user is targeting.

  • Patent number: 10860090
    Abstract: Techniques are disclosed for performing localization of a handheld device with respect to a wearable device. At least one sensor mounted to the handheld device, such as an inertial measurement unit (IMU), may obtain handheld data indicative of movement of the handheld device with respect to the world. An imaging device mounted to either the handheld device or the wearable device may capture a fiducial image containing a number of fiducials affixed to the other device. The number of fiducials contained in the image are determined. Based on the number of fiducials, at least one of a position and an orientation of the handheld device with respect to the wearable device are updated based on the image and the handheld data in accordance with a first operating state, a second operating state, or a third operating state.

  • Patent number: 10829993
    Abstract: A vibration assembly includes a valve above a rotor and stator. The rotor rotates within the stator as fluid flows therethrough. The valve includes a rotating valve segment, which rotates with the rotor, and a non-rotating valve segment each including at least one fluid passage. In an open position, the fluid passages of the valve segments are aligned and a fluid flows through the valve. In a restricted position, the fluid passages of the valve segments are partially or completely unaligned, thereby creating a pressure pulse that is transmitted through the drill string or coiled tubing above the valve. The valve may further include an inner sleeve and an outer sleeve surrounding the non-rotating valve segment. The inner and outer sleeves allow axial sliding but prevent rotation of the non-rotating valve segment. The assembly may further include a lower thrust bearing at a lower end of the rotor.

  • Patent number: 10823549
    Abstract: Examples of a light field metrology system for use with a display are disclosed. The light field metrology may capture images of a projected light field, and determine focus depths (or lateral focus positions) for various regions of the light field using the captured images. The determined focus depths (or lateral positions) may then be compared with intended focus depths (or lateral positions), to quantify the imperfections of the display. Based on the measured imperfections, an appropriate error correction may be performed on the light field to correct for the measured imperfections. The display can be an optical display element in a head mounted display, for example, an optical display element capable of generating multiple depth planes or a light field display.

  • Publication number: 20200319466
    Abstract: Methods and systems are disclosed for presenting virtual objects on a limited number of depth planes using, e.g., an augmented reality display system. A farthest one of the depth planes is within a mismatch tolerance of optical infinity. The display system may switch the depth plane on which content is actively displayed, so that the content is displayed on the depth plane on which a user is fixating. The impact of errors in fixation tracking is addressed using partially overlapping depth planes. A fixation depth at which a user is fixating is determined and the display system determines whether to adjust selection of a selected depth plane at which a virtual object is presented. The determination may be based on whether the fixation depth falls within a depth overlap region of adjacent depth planes. The display system may switch the active depth plane depending upon whether the fixation depth falls outside the overlap region.
