摘要： In a game, multiple players are communicatively coupled with a network. A progression of game action states is tracked. The action states relate to events that occur during the game and a situation of each of the players that corresponds to the events. Upon reaching a first action state, in which a player is expected to utter a first vociferation based on that player's situation with respect to a game event that occurs in association with the first action state, it is detected whether the vociferation is uttered. The first vociferation is captured. The vociferation may be sent to the other players asynchronously with respect to its capture where it may be rendered locally.

摘要： Sound source localization apparatuses and methods are described. A frame amplitude difference vector is calculated based on short time frame data acquired through an array of microphones. The frame amplitude difference vector reflects differences between amplitudes captured by microphones of the array during recording the short time frame data. Similarity between the frame amplitude difference vector and each of a plurality of reference frame amplitude difference vectors is evaluated. Each of the plurality of reference frame amplitude difference vectors reflects differences between amplitudes captured by microphones of the array during recording sound from one of a plurality of candidate locations. A desired location of sound source is estimated based at least on the candidate locations and associated similarity. The sound source localization can be performed based at least on amplitude difference.

摘要： In a class of embodiments, a method and system for calibrating a display using feedback indicative of measurements of light, emitted from the display (typically during display of a test pattern), by a camera device whose camera has a sensitivity function that is unknown a priori but which is operable to measure light emitted by a display in a manner emulating at least one measurement by a reference camera having a known sensitivity function. Typically, the camera device is a handheld camera device including an inexpensive, uncalibrated camera. In another class of embodiments, a system including a display (to be recalibrated), a video preprocessor coupled to the display, and a feedback subsystem including a camera device operable to measure light emitted by the display. The feedback subsystem is coupled and configured to generate preprocessor control parameters in response to measurement data (indicative of measurements by the camera device) and to assert the preprocessor control parameters as calibration feedback to the preprocessor. The preprocessor is operable to calibrate (e.g., recalibrate) the display in response to the control parameters by filtering input image data (e.g., input video data) to be displayed, for example to automatically and dynamically correct for variations in calibration of the display.

摘要： An auditory event boundary detector employs down-sampling of the input digital audio signal without an anti-aliasing filter, resulting in a narrower bandwidth intermediate signal with aliasing. Spectral changes of that intermediate signal, indicating event boundaries, may be detected using an adaptive filter to track a linear predictive model of the samples of the intermediate signal. Changes in the magnitude or power of the filter error correspond to changes in the spectrum of the input audio signal. The adaptive filter converges at a rate consistent with the duration of auditory events, so filter error magnitude or power changes indicate event boundaries. The detector is much less complex than methods employing time-to-frequency transforms for the full bandwidth of the audio signal.
