Abstract: A technique is described herein for presenting notifications associated with applications in a context-based manner. In one implementation, the technique maintains a data store that provides application annotation information that describes a plurality of anchors. For instance, the application annotation information for an illustrative anchor identifies: a location at which the anchor is virtually placed in an interactive world; an application associated with the anchor; and triggering information that describes a set of one or more triggering conditions to be satisfied to enable presentation of a notification pertaining to the application. In use, the technique presents the notification pertaining to the application in prescribed proximity to the anchor when it is determined that the user's engagement with the interactive world satisfies the anchor's set of triggering conditions. The triggering conditions can specify any combination of spatial factors, temporal factors, user co-presence factors, etc.

Abstract: A method for moving a virtual object includes displaying a virtual object and moving the virtual object based on a user input. Based on the user input attempting to move the virtual object in violation of an obstacle, displaying a collision indicator and an input indicator. The collision indicator is moved based on user input and movement constraints imposed by the obstacle. The input indicator is moved based on user input without movement constraints imposed by the obstacle.

Abstract: Examples are disclosed herein that relate to identifying and localizing devices in an environment via an augmented reality display device. One example provides, on a portable augmented reality computing device, a method including establishing a coordinate frame for an environment, and discovering, via a location-sensitive input device, a location of a physical manifestation of the device in the environment, assigning a device location for the device in the coordinate frame based upon the location of the physical manifestation, and modifying an output of the portable augmented reality computing device based upon a change in relative position between the portable augmented reality computing device and the physical manifestation in environment.

Abstract: A visualization system with audio capability includes one or more display devices, one or more microphones, one or more speakers, and audio processing circuitry. While a display device displays an image to a user, a microphone inputs an utterance of the user, or a sound from the user's environment, and provides it to the audio processing circuitry. The audio processing circuitry processes the utterance (or other sound) in real-time to add an audio effect associated with the image to increase realism, and outputs the processed utterance (or other sound) to the user via the speaker in real-time, with very low latency.

Abstract: Examples are disclosed herein that relate to calibrating a user's eye for a stereoscopic display. One example provides, on a head-mounted display device including a see-through display, a method of calibrating a stereoscopic display for a user's eyes, the method including for a first eye, receiving an indication of alignment of a user-controlled object with a first eye reference object viewable via the head-mounted display device from a perspective of the first eye, determining a first ray intersecting the user-controlled object and the first eye reference object from the perspective of the first eye, and determining a position of the first eye based on the first ray. The method further includes repeating such steps for a second eye, determining a position of the second eye based on a second ray, and calibrating the stereoscopic display based on the position of the first eye and the position of the second eye.

Abstract: A head-mounted device includes a gaze detector, a camera, and a communication interface. The gaze detector determines a gaze vector of an eye of a wearer of the head-mounted device. The camera images a physical space including a display of a computing device. The communication interface sends a control signal to the computing device in response to a wearer input. The control signal indicates a location at which the gaze vector intersects the display and useable by the computing device to adjust operation of the computing device.

Abstract: A visualization system with audio capability includes one or more display devices, one or more microphones, one or more speakers, and audio processing circuitry. While a display device displays a holographic image to a user, a microphone inputs an utterance of the user, or a sound from the user's environment, and provides it to the audio processing circuitry. The audio processing circuitry processes the utterance (or other sound) in real-time to add an audio effect associated with the image to increase realism, and outputs the processed utterance (or other sound) to the user via the speaker in real-time, with very low latency.
