Systems and methods are provided for generating, selecting, modifying and/or otherwise configuring occluder(s) used in mixed-reality environments. Pose information of a trackable device worn or carried by a user is determined. Based on that pose information, an assumption regarding the user's own pose is determined. An occluder is then configured in a manner to correspond to the assumed pose of the user for use in the mixed-reality environment. By generating the occluder in this manner, improved battery life by the trackable device can be achieved relative to conventional systems that rely entirely on iterative scanning of the user's body to determine body position.

Dynamic adjustments in mixed-reality environment based on positional assumptions and configurations

Methods for disambiguation and tracking of two or more wireless hand-held controllers with passive optical and inertial tracking within a system having a head mounted virtual or augmented reality display device having a forward facing optical sensor having a field of view, and wherein the display device interfaces with wireless hand-held inertial controllers for providing user input to the display device, with each controller two passive optically reflective markers, one marker being position at or adjacent each end of the controller and being separated by a known distance, and each controller also including an onboard inertial measurement unit for providing inertial data corresponding to its orientation.

Robust optical disambiguation and tracking of two or more hand-held controllers with passive optical and inertial tracking

Examples are disclosed that relate to tracking a pose of a handheld object used with a head-mounted display device. In one example, a method comprises: receiving image data from an image sensing system; detecting a plurality of feature points of the handheld object in a frame of the image data; receiving inertial measurement unit (IMU) data from an IMU of the handheld object; based on detecting the plurality of feature points and receiving the IMU data, determining a first pose of the handheld object; determining that at least a portion of the plurality of feature points is not detected in another frame of the image data; using the IMU data, updating the first pose of the handheld object to a second pose; and body-locking the second pose of the handheld object to a body location on a user wearing the head-mounted display device.

Tracking pose of handheld object

A server set may provide a document service to various clients in view of considerations such as availability, fault tolerance, flexibility, and performance. Presented herein are document service architectures that involve partitioning the document set into at least two document ranges, and assigning the respective document ranges to an agent that is deployed to at least one assigned server. A request to apply an operation to a selected document may be fulfilled by identifying the document range of the document; identifying a selected server of the server set that hosts the agent to which the range is assigned; and forwarding the request to the selected server. In some variations, servers may retain detailed information about neighboring servers (e.g., according to logical and/or physical proximity) and scant information about distant servers, thereby avoiding both the extensive information exchange of highly informed network architectures and the inefficiency of uninformed routing algorithms.

Elastically scalable document-oriented storage services

In embodiments of a camera-based input device, the input device includes an inertial measurement unit that collects motion data associated with velocity and acceleration of the input device in an environment, such as in three-dimensional (3D) space. The input device also includes at least two visual light cameras that capture images of the environment. A positioning application is implemented to receive the motion data from the inertial measurement unit, and receive the images of the environment from the at least two visual light cameras. The positioning application can then determine positions of the input device based on the motion data and the images correlated with a map of the environment, and track a motion of the input device in the environment based on the determined positions of the input device.

Position-determining input device

Systems are provided that include a wireless hand-held inertial controller with passive optical and inertial tracking in a slim form-factor. These systems are configured for use with a head mounted virtual or augmented reality display device (HMD) that operates with six degrees of freedom by fusing (i) data related to the position of the controller derived from a forward-facing optical sensor located in the HMD with (ii) data relating to the orientation of the controller derived from an inertial measurement unit located in the controller.

Passive optical and inertial tracking in slim form-factor

A mixed reality system may comprise a head-mounted display (HMD) device with a location sensor and a base station, mounted a predetermined offset from the location sensor, that emits an electromagnetic field (EMF). An EMF sensor affixed to an object may sense the EMF, forming a magnetic tracking system. The HMD device may determine a relative location of the EMF sensor therefrom and determine a location of the EMF sensor in space based on the relative location, the predetermined offset, and the location of the location sensor. An optical tracking system comprising a marker an optical sensor configured to capture optical data may be included to augment the magnetic tracking system based on the optical data and a location of the optical sensor or marker. The HMD device may display augmented reality images and overlay a hologram corresponding to the location of the EMF sensor over time.

Optically augmenting electromagnetic tracking in mixed reality

A modular holding fixture for selectively coupling to a wireless hand-held inertial controller to provide passive optical and inertial tracking in a slim form-factor for use with a head mounted display that operates with six degrees of freedom by fusing (i) data related to the position of the controller derived from a forward-facing depth camera located in the head mounted display with (ii) data relating to the orientation of the controller derived from an inertial measurement unit located in the controller.

Systems and methods are described that provide a wireless hand-held inertial controller for use with a head-mounted, augmented reality (AR) or virtual reality (VR) display or other conventional display that operates with six degrees of freedom by fusing (i) data related to the position of the hand-held inertial controller derived from a depth camera located on the display with (ii) data relating to the orientation of the hand-held inertial controller derived from an inertial measurement unit located in the hand-held inertial controller.

Six DOF mixed reality input by fusing inertial handheld controller with hand tracking

A server set may provide a document service to one or more clients, and may be configured to do so in view of various considerations such as availability, fault tolerance, flexibility, and performance. Presented herein are document service architectures that involve partitioning the document set into at least two document ranges, and configuring respective servers of the server set to host one or more agents to which are respectively assigned one or more document ranges. A request for an operation involving at least one document may be routed to a server hosting an agent managing the document ranges of the documents involved in the operation. Moreover, respective servers may retain detailed information about neighboring servers (e.g., according to a logical or physical proximity) and scant information about distant servers, thereby avoiding both the extensive information exchange of highly informed network architectures and the inefficiency of uninformed routing algorithms.
