Abstract: A system and method are disclosed for building virtual content from within a virtual environment using virtual tools to build and modify the virtual content.

Abstract: Various techniques are described to protect secrets held by closed computing devices. In an ecosystem where devices operate and are offered a wide range of services from a service provider, the service provider may want to prevent users from sharing services between devices. In order to guarantee that services are not shared between devices, each device can be manufactured with a different set of secrets such as per device identifiers. Unscrupulous individuals may try to gain access to the secrets and transfer secrets from one device to another. In order to prevent this type of attack, each closed computing system can be manufactured to include a protected memory location that is tied to the device.

Abstract: An augmented reality system that provides augmented product and environment information to a wearer of a see through head mounted display. The augmentation information may include advertising, inventory, pricing and other information about products a wearer may be interested in. Interest is determined from wearer actions and a wearer profile. The information may be used to incentivize purchases of real world products by a wearer, or allow the wearer to make better purchasing decisions. The augmentation information may enhance a wearer's shopping experience by allowing the wearer easy access to important product information while the wearer is shopping in a retail establishment. Through virtual rendering, a wearer may be provided with feedback on how an item would appear in a wearer environment, such as the wearer's home.

Abstract: Methods for providing real-time feedback to an end user of a mobile device as they are interacting with or manipulating one or more virtual objects within an augmented reality environment are described. The real-time feedback may comprise visual feedback, audio feedback, and/or haptic feedback. In some embodiments, a mobile device, such as a head-mounted display device (HMD), may determine an object classification associated with a virtual object within an augmented reality environment, detect an object manipulation gesture performed by an end user of the mobile device, detect an interaction with the virtual object based on the object manipulation gesture, determine a magnitude of a virtual force associated with the interaction, and provide real-time feedback to the end user of the mobile device based on the interaction, the magnitude of the virtual force applied to the virtual object, and the object classification associated with the virtual object.

Abstract: Methods for positioning virtual objects within an augmented reality environment using snap grid spaces associated with real-world environments, real-world objects, and/or virtual objects within the augmented reality environment are described. A snap grid space may comprise a two-dimensional or three-dimensional virtual space within an augmented reality environment in which one or more virtual objects may be positioned. In some embodiments, a head-mounted display device (HMD) may identify one or more grid spaces within an augmented reality environment, detect a positioning of a virtual object within the augmented reality environment, determine a target grid space of the one or more grid spaces in which to position the virtual object, determine a position of the virtual object within the target grid space, and display the virtual object within the augmented reality environment based on the position of the virtual object within the target grid space.

Abstract: Embodiments that relate to displaying holographic keyboard and hand images in a holographic environment are provided. In one embodiment depth information of an actual position of a user's hand is received. Using the depth information, a holographic hand image representing the user's hand is displayed in a virtual hand plane in the holographic environment. In response to receiving a keyboard activation input from the user and using the depth information, the holographic keyboard image is adaptively displayed in a virtual keyboard plane in the holographic environment at a virtual distance under the holographic hand image representing the user's hand.

Abstract: Assisted viewing of web-based resources by an end user of a head-mounted display device (HMD) is described. An HMD may display content from web-based resources using a see-through display while tracking eye and head movement of the end user viewing the content within an augmented reality environment. Active view regions within the see-through display are identified based on tracking information including eye gaze data and head direction data. The web-based resources are analyzed to identify content and display elements. The analysis is correlated with the active view regions to identify the underlying content that is a desired point of focus of a corresponding active view region, as well as to identify the display elements corresponding to that content. A web-based resource is modified based on the correlation. The content from the web-based resource is displayed based on the modifications to assist the end user in viewing the web-based resource.

The method further includes distinguishing features in one coordinate frame from features in another coordinate frame based upon the motion data.

Abstract: Embodiments are disclosed herein that relate to tuning gesture recognition characteristics for a device configured to receive gesture-based user inputs. For example, one disclosed embodiment provides a head-mounted display device including a plurality of sensors, a display configured to present a user interface, a logic machine, and a storage machine that holds instructions executable by the logic machine to detect a gesture based upon information received from a first sensor of the plurality of sensors, perform an action in response to detecting the gesture, and determine whether the gesture matches an intended gesture input. The instructions are further executable to update a gesture parameter that defines the intended gesture input if it is determined that the gesture detected does not match the intended gesture input.

Abstract: An example wearable display system includes a controller, a left display to display a left-eye augmented reality image with a left-eye display size at left-eye display coordinates, and a right display to display a right-eye augmented reality image with a right-eye display size at right-eye display coordinates, the left-eye and right-eye augmented reality images collectively forming an augmented reality object perceivable at an apparent real world depth by a wearer of the display system. The controller sets the left-eye display coordinates relative to the right-eye display coordinates as a function of the apparent real world depth of the augmented reality object. The function maintains an aspect of the left-eye and right-eye display sizes throughout a non-scaling range of apparent real world depths of the augmented reality object, and the function scales the left-eye and right-eye display sizes with changing apparent real world depth outside the non-scaling range.

Abstract: A see-through, near-eye, mixed reality display device and system for collaboration amongst various users of other such devices and personal audio/visual devices of more limited capabilities. One or more wearers of a see through head mounted display apparatus define a collaboration environment. For the collaboration environment, a selection of collaboration data and the scope of the environment are determined. Virtual representations of the collaboration data in the field of view of the wearer, and other device users are rendered. Persons in the wearer's field of view to be included in collaboration environment and who are entitled to share information in the collaboration environment are defined by the wearer. If allowed, input from other users in the collaboration environment on the virtual object may be received and allowed to manipulate a change in the virtual object.

Abstract: Methods for recognizing gestures using adaptive multi-sensor gesture recognition are described. In some embodiments, a gesture recognition system receives a plurality of sensor inputs from a plurality of sensor devices and a plurality of confidence thresholds associated with the plurality of sensor inputs. A confidence threshold specifies a minimum confidence value for which it is deemed that a particular gesture has occurred. Upon detection of a compensating event, such as excessive motion involving one of the plurality of sensor devices, the gesture recognition system may modify the plurality of confidence thresholds based on the compensating event. Subsequently, the gesture recognition system generates a multi-sensor confidence value based on whether at least a subset of the plurality of confidence thresholds has been satisfied. The gesture recognition system may also modify the plurality of confidence thresholds based on the plugging and unplugging of sensor inputs from the gesture recognition system.

Abstract: Methods for enabling hands-free selection of objects within an augmented reality environment are described. In some embodiments, an object may be selected by an end user of a head-mounted display device (HMD) based on detecting a vestibulo-ocular reflex (VOR) with the end user's eyes while the end user is gazing at the object and performing a particular head movement for selecting the object. The object selected may comprise a real object or a virtual object. The end user may select the object by gazing at the object for a first time period and then performing a particular head movement in which the VOR is detected for one or both of the end user's eyes. In one embodiment, the particular head movement may involve the end user moving their head away from a direction of the object at a particular head speed while gazing at the object.
