1. A method for detecting a position of an object by a position detection device, the method comprising:
detecting a position of the object in a sensing zone, which is formed in a predetermined zone in front of a display screen and is divided into multiple divided sensing zones along a first direction, by causing multiple light-emitting elements disposed along the first direction to emit light sequentially along the first direction and measuring an intensity and a reception time point of a reflected signal by using a light-receiving element;
increasing a size of at least one of the multiple divided sensing zones that corresponds to the detected position of the object; and
reflecting and displaying the detected position of the object on the display screen based on the increased size of at least one of the multiple divided sensing zones.
