Claim 18:
19. A method of operating a wireless tag communication device to guide an operator toward a wireless tag, the method comprising:
communicating with the wireless tag through a directional antenna;
capturing, by a camera, a first image along a shooting direction, the shooting direction coinciding with a direction along which a signal strength of the directional antenna is maximized;
estimating a tag direction where the wireless tag exists;
estimating a position of the wireless tag communication device;
estimating a position of the wireless tag based on the estimated tag direction and the estimated position of the wireless tag communication device;
displaying, by a display, the first image captured by the camera and a second image showing an explicit area containing the estimated position of the wireless tag, the second image being superimposed on the first image; and
increasing a size of the explicit area in response to a determination that a distance between the estimated position of the wireless tag and the estimated position of the wireless tag communication device has decreased.
