Abstract: Methods for tracking the head position of an end user of a head-mounted display device (HMD) relative to the HMD are described. In some embodiments, the HMD may determine an initial head tracking vector associated with an initial head position of the end user relative to the HMD, determine one or more head tracking vectors corresponding with one or more subsequent head positions of the end user relative to the HMD, track head movements of the end user over time based on the initial head tracking vector and the one or more head tracking vectors, and adjust positions of virtual objects displayed to the end user based on the head movements. In some embodiments, the resolution and/or number of virtual objects generated and displayed to the end user may be modified based on a degree of head movement of the end user relative to the HMD.

Abstract: Various embodiments are disclosed that relate to detecting mobile operator networks. For example, one disclosed embodiment provides a method of operating a catalog server to which a mobile computing device connects via a computer network path that traverses a mobile operator network. The method may include receiving data from a mobile device, the data including a locale and a mobile operator identifier stored in memory on the mobile device; searching a database to find a store based on the mobile operator identifier and the locale; if a store is found, populating settings based on the store; and sending configuration information to the mobile device based on the settings.

Abstract: Methods for recognizing gestures within a near-field environment are described. In some embodiments, a mobile device, such as a head-mounted display device (HMD), may capture a first image of an environment while illuminating the environment using an IR light source with a first range (e.g., due to the exponential decay of light intensity) and capture a second image of the environment without illumination. The mobile device may generate a difference image based on the first image and the second image in order to eliminate background noise due to other sources of IR light within the environment (e.g., due to sunlight or artificial light sources). In some cases, object and gesture recognition techniques may be applied to the difference image in order to detect the performance of hand and/or finger gestures by an end user of the mobile device within a near-field environment of the mobile device.

Abstract: The present disclosure is directed to a wearable, reprogrammable electronic display device that is configured to present user selected content with little to no power. The electronic display device may be programmed to display a specific image or string of text to be worn by the user. A personal computing device is configured to wirelessly or directly communicate with the electronic display device to program the content into the display device.

Abstract: A wrist-worn input device that is used in augmented reality (AR) operates in three modes of operation. In a first mode of operation, the input device is curved so that it may be worn on a user's wrist. A touch surface receives letters gestured or selections by the user. In a second mode of operation, the input device is flat and used as a touch surface for more complex single or multi-hand interactions. A sticker defining one or more locations on the touch surface that corresponds a user's input, such as a character, number or intended operation, may be affixed to the touch surface. The sticker may be interchanged with different stickers based on a mode of operation, user's preference and/or particular AR experience. In a third mode of operation, the input device receives biometric input from biometric sensors. The biometric input may provide contextual information in an AR experience while allowing the user to have their hands free.

Abstract: Systems and methods for integrating third-party content and first-party content in a marketplace environment for presentation to a user of a computing device are provided. The method may include receiving content and publisher-specific metadata from a plurality of third-party publishers; storing the content and publisher-specific metadata in a catalog database. The database may include third-party publisher content and first-party content. The method may further include receiving a catalog query from a client device, identifying a set of catalogs to which a user of the client device belongs; generating query results, the query results including third-party publisher content and first-party content; filtering query results based on the metadata and set of catalogs; and sending the filtered query results to the client device for display on the client device.
