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.
