    Abstract: A head-mounted device (HMD) may be used to determine an access request for accessing a device. An identifier identifying the device may be received at the HMD and from the device. By verifying receipt of the identifier at the HMD, and that access rights associated with the HMD enable granting of the access request, the access request may be granted.

    Abstract: Systems and methods are described for authenticating devices. The systems and methods may include detecting, by a sensor on a wearable device, at least one cloud anchor that includes an identifier associated with a network and configured for a physical environment. In response to detecting that a location associated with the at least one cloud anchor is within a threshold distance of the wearable device and detecting that the wearable device has access to the at least one cloud anchor, triggering extraction of the identifier from the at least one cloud anchor. The systems and methods may also include joining the wearable device to the network based on a received authentication corresponding to the extracted identifier.

    Abstract: The present disclosure relates generally to the processing of machine-readable visual encodings in view of contextual information. One embodiment of aspects of the present disclosure comprises obtaining image data descriptive of a scene that includes a machine-readable visual encoding; processing the image data with a first recognition system configured to recognize the machine-readable visual encoding; processing the image data with a second, different recognition system configured to recognize a surrounding portion of the scene that surrounds the machine-readable visual encoding; identifying a stored reference associated with the machine-readable visual encoding based at least in part on one or more first outputs generated by the first recognition system based on the image data and based at least in part on one or more second outputs generated by the second recognition system based on the image data; and performing one or more actions responsive to identification of the stored reference.

    Abstract: A computer-implemented method comprises: detecting, by a first computer system, first content of a tangible instance of a first document; generating, by the first computer system, a first hash using the first content, the first hash including first obfuscation content; sending, by the first computer system, the first hash for receipt by a second computer system; and receiving, by the first computer system, a response to the first hash generated by the second computer system, the response including information corresponding to a second document associated with the first content.

    Abstract: A computer-implemented method includes receiving a two-dimensional image of a scene captured by a camera, recognizing one or more objects in the scene depicted in the two-dimensional image, and determining whether the one or more recognized objects have known real-world dimensions. The computer-implemented method further includes determining a depth of at least one recognized object having known real-world dimensions from the camera, and overlaying three-dimensional (3-D) augmented reality content over a display the 2-D image of the scene considering the depth of the at least one recognized object from the camera.

    Abstract: Audiovisual presentations, such as film recordings, may have been originally created having an audio soundtrack with multiple audio tracks mixed for a surround sound system that includes a set of speakers physically surrounding a user. The present disclosure presents systems and methods to remix these soundtracks into 3D audio that when presented to the ears of a user can be perceived as a virtual surround sound system that mimics the physical system. What is more, the disclosed systems and methods can enhance the virtual surround sound system by adjusting virtual speakers of the virtual surround sound system according to video content of the audiovisual presentation. Further enhancement may be possible by adjusting the virtual speakers of the virtual surround sound system according to a sensed position of a user.
