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: 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 from a capture device. The user's hand is spaced by an initial actual distance from the capture device, and a holographic keyboard image is displayed spatially separated by a virtual distance from a holographic hand image. The user's hand is determined to move to an updated actual distance from the capture device. In response, the holographic keyboard image is maintained spatially separated by substantially the virtual distance from the holographic hand image.

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: Embodiments are disclosed that relate to operating a user interface on an augmented reality computing device comprising a see-through display system. For example, one disclosed embodiment includes identifying one or more objects located outside a field of view of a user, and for each object of the one or more objects, providing to the user an indication of positional information associated with the object.

Abstract: Technology is described for web-like hierarchical menu interface which displays a menu in a web-like hierarchical menu display configuration in a near-eye display (NED). The web-like hierarchical menu display configuration links menu levels and menu items within a menu level with flexible spatial dimensions for menu elements. One or more processors executing the interface select a web-like hierarchical menu display configuration based on the available menu space and user head view direction determined from a 3D mapping of the NED field of view data and stored user head comfort rules. Activation parameters in menu item selection criteria are adjusted to be user specific based on user head motion data tracked based on data from one or more sensors when the user wears the NED. Menu display layout may be triggered by changes in head view direction of the user and available menu space about the user's head.

Abstract: Methods for generating and displaying personalized virtual billboards within an augmented reality environment are described. The personalized virtual billboards may facilitate the sharing of personalized information between persons within an environment who have varying degrees of acquaintance (e.g., ranging from close familial relationships to strangers). In some embodiments, a head-mounted display device (HMD) may detect a mobile device associated with a particular person within an environment, acquire a personalized information set corresponding with the particular person, generate a virtual billboard based on the personalized information set, and display the virtual billboard on the HMD. The personalized information set may include information associated with the particular person such as shopping lists and classified advertisements.

Abstract: Embodiments that relate to providing motion amplification to a virtual environment are disclosed. For example, in one disclosed embodiment a mixed reality augmentation program receives from a head-mounted display device motion data that corresponds to motion of a user in a physical environment. The program presents via the display device the virtual environment in motion in a principal direction, with the principal direction motion being amplified by a first multiplier as compared to the motion of the user in a corresponding principal direction. The program also presents the virtual environment in motion in a secondary direction, where the secondary direction motion is amplified by a second multiplier as compared to the motion of the user in a corresponding secondary direction, and the second multiplier is less than the first multiplier.

Abstract: A method and apparatus are provided for fabricating of continuous castings with fine and uniform microstructure, which can be used as feedstock for secondary processing routes, such as thixoforming, forging and machining or direct application in industry. An overheated liquid alloy is fed into a high shear device (for example, a twin-screw extruder) and sheared intensively to produce a sheared liquid alloy or a semisolid slurry, wherein the sheared liquid alloy is at a temperature close to its liquidus and the semisolid slurry is then transferred to a shaping device for production of continuous castings with fine and uniform microstructures through a solidification process. The shaping device is any device capable of forming continuous (i.e.
