摘要: A device includes a microphone array fixed to the device. signal processor produces an audio output using beamforming with input from array. The aims in selected direction. An orientation sensor—such as compass, accelerometer, or inertial sensor—is coupled processor. sensor detects change of and provides for adjusting aim maintain may include camera that captures image. image identify source provide direction follow source. receive adjust changes before tracking movement
