1. A method for approximating a source position of a sound-causing event for determining an input used in operating an electronic device, the method comprising:

  • monitoring an area using a plurality of detection points for an occurrence of the event at any location within the area;

    detecting a sound caused by the event occurring at a location corresponding to the source position using the plurality of detection points, the source position being within the area that is being monitored;

    independently of knowing a time in which the sound of the event is emitted, recording information about the sound at individual detection points in the plurality of detections points, the information being dependent on a distance between the source position and each of the individual detection points;

    determining, approximately, the source position based on the recorded information and on a relative position of individual detection points in the plurality of detection points to other detection points in the plurality of detection points;

    determining the input from the source position; and

    causing an operation to be performed by the electronic device based on the input.
