Abstract
A wireless tag communication device includes a directional antenna, a communication control circuit configured to communicate with a wireless tag through the directional antenna, a camera positioned such that a direction along which a signal strength of the directional antenna is maximized and a shooting direction of the camera coincide with each other, and a controller. The controller is configured to estimate a tag direction where the wireless tag exists, estimate a position of the wireless tag communication device, estimate a position of the wireless tag based on the estimated tag direction and the estimated position of the wireless tag communication device, and control a display to display a first image captured by the camera and a second image showing an explicit area containing the estimated position of the wireless tag.
