Systems and methods are disclosed in which a playback device transmits a first sound signal including a predetermined waveform. In one example, the playback device receives a second sound signal including at least one reflection of the first sound signal. The second sound signal is processed to determine a location of a person relative to the playback device, and a characteristic of audio reproduction by the playback device is selected, based on the determined location of the person.

A tracking-distance-measuring system capable of tracking a torso object is provided. The tracking-distance-measuring system includes: an image sensor, a controller, a distance-measuring device, and an actuator device. The image sensor is configured to capture an input image. The controller is configured to analyze the input image to recognize a torso object from the input image, and calculate an offset distance between a center of the torso object and a central axis of the input image. The actuator device is configured to carry the distance-measuring device. The controller controls the actuator device to calibrate an offset angle between the distance-measuring device and the recognized torso object according to the offset distance. In response to calibrating the offset angle, the distance-measuring device emits energy and receives reflected energy to detect an object distance of the torso object.
