1. A method for obtaining a position of a person who is using an audiovisual entertainment system, the method comprising:
controlling an audio source to output an audio signal at a first time;
determining a second time at which the audio signal arrives at an audio detector, wherein the peripheral device comprises the audio source and the audio detector and the acoustic signal undergoes a reflection between the audio source and the audio detector; and
estimating a position of the peripheral device based on an acoustic time-of-flight between the first time and the second time to obtain the position of the peripheral device;
obtaining an orientation of the peripheral device;
selecting an offset between the person and peripheral device based on the obtained orientation; and
estimating the position of the person based on the selected offset and the estimated position of the peripheral device.
