Abstract: A method for detecting full-body gestures by a mobile device includes a host mobile device detecting the tracked body of a co-located participant in a multi-party session. When the participant's tracked body provides a full-body gesture, the host's mobile device recognizes that there is a tracked body providing a full-body gesture. The host mobile device iterates through the list of participants in the multi-party session and finds the closest participant mobile device with respect to the screen-space position of the head of the gesturing participant. The host mobile device then obtains the user ID of the closest participant mobile device and broadcasts the recognized full-body gesture event to all co-located participants in the multi-party session, along with the obtained user ID. Each participant's mobile device may then handle the gesture event as appropriate for the multi-party session. For example, a character or costume may be assigned to a gesturing participant.

Abstract: Described are recording tools for generating following behaviors and creating interactive AR experiences. The following recording application enables a user with little or no programming skills to virtually connect virtual objects to other elements, including virtual avatars representing fellow users, thereby creating an interactive story in which multiple elements are apparently and persistently connected. The following interface includes methods for selecting objects and instructions for connecting a virtual object to a target object. In one example, the recording application presents on the display a virtual tether between the objects until a connecting action is detected. The following interface is presented on the display as an overlay, in the foreground relative to the physical environment.

Abstract: Described are virtual AR interfaces for generating a virtual rotational interface for the purpose of controlling connected IoT devices using the inertial measurement unit (IMU) of a portable electronic device. The IMU control application enables a user of a portable electronic device to activate a virtual rotational interface overlay on a display and adjust a feature of a connected IoT product by rotating a portable electronic device. The device IMU moves a slider on the virtual rotational interface. The IMU control application sends a control signal to the IoT product which executes an action in accordance with the slider position. The virtual rotational interface is presented on the display as a virtual object in an AR environment. The IMU control application detects the device orientation (in the physical environment) and in response presents a corresponding slider element on the virtual rotational interface (in the AR environment).

Abstract: Multi-player co-located AR experiences are augmented by assigning characters and costumes to respective participants (a.k.a. “users” of AR-enabled mobile devices) in multi-player AR sessions for storytelling, play acting, and the like. Body tracking technology and augmented reality (AR) software are used to decorate the bodies of the co-located participants with virtual costumes within the context of the multi-player co-located AR experiences. Tracked bodies are distinguished to determine which body belongs to which user and hence which virtual costume belongs to which tracked body so that corresponding costumes may be assigned for display in augmented reality. A host-guest mechanism is used for networked assignment of characters and corresponding costumes in the co-located multi-player AR session. Body tracking technology is used to move the costume with the body as movement of the assigned body is detected.

Abstract: A virtual interface application presented in augmented reality (AR) is described for controlling Internet of Things (IoT) products. The virtual interface application enables a user of a portable electronic device to activate a virtual control interface overlay on a display, receive a selection from the user using her hands or feet, and send a control signal to a nearby IoT product which executes an action in accordance with the selection. The virtual control interface is presented on the display as a virtual object in an AR environment. The virtual interface application includes a foot tracking tool for detecting an intersection between the foot location (in the physical environment) and the virtual surface position (in the AR environment). When an intersection is detected, the virtual interface application sends a control signal with instructions to the IoT product.

Abstract: Recording tools for creating interactive AR experiences. An interaction recording application enables a user with little or no programming skills to perform and record user behaviors that are associated with reactions between story elements such as virtual objects and connected IoT devices. The user behaviors include a range of actions, such as speaking a trigger word and apparently touching a virtual object. The corresponding reactions include starting to record a subsequent scene and executing actions between story elements. The trigger recording interface is presented on the display as an overlay relative to the physical environment.

Abstract: Described are authoring tools for creating interactive AR experiences. The story-authoring application enables a user with little or no programming skills to create an interactive story that includes recording voice commands for advancing to the next scene, inserting and manipulating virtual objects in a mixed-reality environment, and recording a variety of interactions with connected IoT devices. The story creation interface is presented on the display as a virtual object in an AR environment.

Abstract: Systems, methods, and computer readable media directed to multi-user visual experiences such as interactive gaming experiences and artistic media experiences. A viewing electronic device includes a camera configured to capture images, a display, and a processor coupled to the camera and the display. The processor is configured to capture, with the camera, images of a rotating marker where the rotating marker is presented on a monitor of a remote device and to present, on the display, a visual experience where the visual experience has an adjustable feature. The processor detects a parameter of the rotating marker from the captured images that corresponds to the adjustable feature and updates the visual experience responsive to the detected parameter. The parameter may be one or more of an angle, speed of rotation, direction of rotation, color, or pattern of the rotating marker.

Abstract: A method of making an electromagnetic coil for use in a high-temperature electromagnetic machine includes pre-coating magnet wire with a high-temperature insulation precursor to produce pre-coated magnet wire, winding, while applying in-situ a glass-ceramic slurry, the pre-coated magnet wire into a predetermined coil shape to produce a wet-wound green coil, and thermally processing the wet-wound green coil to produce a processed coil. In some instances, a second layer of a high-temperature insulation may be applied to the processed coil to produce a further insulated processed coil, and then thermally processing the further insulated processed coil to produce a further processed electromagnetic coil.

Abstract: A method for determining a health indication of a mechanical component includes: receiving, by a processor of a multi-sensor node device having a plurality of sensors, a configuration defining activation of the plurality of sensors based on a type of mechanical component to which the multi-sensor node device is coupled and based on a level of energy harvesting available at the multi-sensor node device; determining to activate a first sensor based on the received configuration; collecting data from the first sensor relating to a first parameter of the mechanical component; determining to activate a second sensor based on determining that the data collected from the first sensor indicates a threshold is exceeded; collecting data from the second sensor relating to a second parameter of the mechanical component; determining an initial health indication of the mechanical component; and transmitting the determined initial health indication to a remote computing system.

Abstract: A sealed battery pack is provided that prevents liquid, dust and gas from compromising the reliability of the rechargeable cell and circuitry disposed within the pack. A rechargeable cell and printed circuit board are coupled together and are placed into a five sided housing. In one embodiment, one of the sides is longer that the others to accommodate electrical contacts for coupling to a host device. Once the cell/board assembly is positioned in the housing, plastic is drawn through the housing using an insert molding process to seal and encapsulate the cell and board within the housing. The seal provided by the insert molding process ensures that liquid, gas and dust do not penetrate the pack.
