    Abstract: An apparatus for calibrating an augmented reality (AR) device having an optical see-through head mounted display (HMD) obtains eye coordinates in an eye coordinate system corresponding to a location of an eye of a user of the AR device, and obtains object coordinates in a world coordinate system corresponding to a location of a real-world object in the field of view of the AR device, as captured by a scene camera having a scene camera coordinate system. The apparatus calculates screen coordinates in a screen coordinate system corresponding to a display point on the HMD, where the calculating is based on the obtained eye coordinates and the obtained object coordinates. The apparatus calculates calibration data based on the screen coordinates, the object coordinates and a transformation from the target coordinate system to the scene camera coordinate system. The apparatus then derives subsequent screen coordinates for the display of AR in relation to other real-world object points based on the calibration data.

    Abstract: Some implementations provide a method for identifying a speaker. The method determines position and orientation of a second device based on data from a first device that is for capturing the position and orientation of the second device. The second device includes several microphones for capturing sound. The second device has movable position and movable orientation. The method assigns an object as a representation of a known user. The object has a moveable position. The method receives a position of the object. The position of the object corresponds to a position of the known user. The method processes the captured sound to identify a sound originating from the direction of the object. The direction of the object is relative to the position and the orientation of the second device. The method identifies the sound originating from the direction of the object as belonging to the known user.

    Abstract: Methods and apparatuses for providing tangible control of sound are provided and described as embodied in a system that includes a sound transducer array along with a touch surface-enabled display table. The array may include a group of transducers (multiple speakers and/or microphones) configured to perform spatial processing of signals for the group of transducers so that sound rendering (in configurations where the array includes multiple speakers), or sound pick-up (in configurations where the array includes multiple microphones), have spatial patterns (or sound projection patterns) that are focused in certain directions while reducing disturbances from other directions. Users may directly adjust parameters related to sound projection patterns by interacting with the touch surface while receiving visual feedback by exercising one or more commands on the touch surface. The commands may be adjusted according to visual feedback received from the change of the display on the touch surface.

    Abstract: Access terminals are adapted to facilitate automated wireless communication interactions based on implicit user cues. According to one example, an access terminal can obtain a plurality of user cues, including user cues from at least two primary sensor inputs, as well as other optional user cues. The access terminal may identify the occurrence of a predefined combination of user cues from among the plurality of user cues. In response to the identification of the predefined combination of user cues, the access terminal may affect a wireless communication link with an access terminal associated with another user. Other aspects, embodiments, and features are also included.

    Abstract: A method, an apparatus, and a computer program product provide feedback to a user of an augmented reality (AR) device having an optical see-through head mounted display (HMD). The apparatus obtains a location on the HMD corresponding to a user interaction with an object displayed on the HMD. The object may be an icon on the HMD and the user interaction may be an attempt by the user to select the icon through an eye gaze or gesture. The apparatus determines whether a spatial relationship between the location of user interaction and the object satisfies a criterion, and outputs a sensory indication, e.g., visual display, sound, vibration, when the criterion is satisfied. The apparatus may be configured to output a sensory indication when user interaction is successful, e.g., the icon was selected. Alternatively, the apparatus may be configured to output a sensory indication when the user interaction fails.
