Abstract: Systems and methods for controlling variable-focus functionality to reduce user discomfort in a mixed-reality system implement acts of obtaining a vergence depth of a gaze of a user, determining that the variable-focus lens for providing focus on virtual content viewed by the user is currently configured to provide focus at a depth that differs from the vergence depth, detecting that a triggering condition is present, and, in response to so detecting, selectively dampening an adjustment made to the variable-focus lens. In some implementations, the dampening causes the adjustment made to the variable-focus lens to reconfigure the variable-focus lens to provide focus at a depth that differs from the vergence depth.

Abstract: One example provides, on a computing device comprising a display, a method of initiating and conducting voice communication with a contact. The method comprises displaying a user interface on the display, receiving a user input of a position signal for the user interface, and determining that the position signal satisfies a selection condition for a contact based on a location of the position signal on the user interface and a position of a proxy view of the contact on the user interface. The method further comprises, in response to determining that the position signal satisfies the selection condition, selecting the contact for communication, receiving voice input, and responsive to receiving the voice input while the contact is selected for communication, opening a voice communication channel with the contact and sending the voice input to the contact via the voice communication channel.

Abstract: A wearable, head-mounted display system includes a near-eye display to display an augmented reality object perceivable at an apparent real world depth and an apparent real world location by a wearer of the head-mounted display system, and a controller to adjust the apparent real world location of the augmented reality object as a function of a field of view (FOV) of the wearer. The function is based on a bounding region of the augmented reality object and one or more overlap parameters between the bounding region of the augmented reality object and the FOV of the wearer.

Abstract: A method for operating a head-mounted computing device that includes displaying an image of an environment on a display of the head-mounted computing device and identifying a surface within the image that is eligible for color fill operation, based on similarities in color parameters of contiguous pixels in the captured image. The method further includes displaying an indicator prompting user input regarding color fill, receiving a color fill request via user input, the request being for a predetermined color, and performing a color fill operation on the identified surface in response to receiving the color fill request by (a) generating a fill image having the predetermined color and a shape that conforms to the shape of the identified surface, and (b) displaying the fill image in a world-locked manner so as to overlay the identified surface even when a perspective of the display changes.

Abstract: A method to provide visual feedback for gazed-based user-interface navigation includes presenting, on a display, a first image representing a digital object available for user interaction, recognizing a user gaze axis, and computing a point of intersection of the user gaze axis through the first image. An offset distance between the point of intersection and a reference position of the first image then recognized, and a second image is presented on the display. The second image is presented displaced from the point of intersection by an amount dependent on the offset distance.

Abstract: A conferencing system includes a display device that displays video received from a remote communication device of a communication partner. An audio stream is transmitted to the remote communication device. The audio stream includes real-world sounds produced by one or more real-world audio sources captured by a microphone array and virtual sounds produced by one or more virtual audio sources. A relative volume of sounds in the audio stream is selectively adjusted based, at least in part, on real-world positioning of corresponding audio sources, including real-world and/or virtualized audio sources.

Abstract: A method is disclosed that includes receiving an instruction to generate a virtual place-located anchor at a virtual location that is world-locked. Data items from a target data source are received. A subset of the data items is linked to the virtual place-located anchor. A first display device is caused to display virtual content of the subset of data items at the virtual place-located anchor. If a condition under which a second user is authorized to view the virtual content is satisfied, a second display device is caused to display the virtual content at the virtual place-located anchor.

Abstract: A method for displaying holograms may include displaying an initial hologram via a display device comprising an at least partially see-through display, the initial hologram located on a virtual surface at an initial virtual location. Subsequently, an instruction is received to display a subsequent hologram on the virtual surface at a subsequent virtual location. Collision detection is performed to determine that the subsequent hologram would collide with the initial hologram. In response, the subsequent hologram is displayed at an adjusted virtual location that is closer to the display device than the initial virtual location of the initial hologram.

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.
