摘要

PROBLEM TO BE SOLVED: To provide a retrieval device for obtaining specific length which should be specified as a retrieval query from a position of an object whose position is determined based on the intention of a user.

SOLUTION: In a retrieval device 101, a detection part 102 detects the respective position of a plurality of objects whose positions change based on the intention of a user in a real space. A calculation part 103 calculates specific length based on the intention of the user from the detected positions of the objects. A retrieval part 104 retrieves a commodity record with commodity size which satisfies retrieval conditions based on the calculated specific length from a commodity database by which the commodity record at least with the commodity size, and a commodity image is managed. A display part 105 displays the commodity image which the retrieved commodity record has on a screen.
