Abstract

An ID-tag-based explanation system in which different kind of explanations are executed according to the combination of a plurality of ID tags is provided.

The ID-tag-based explanation system comprises ID tags attached to a plurality of explanation objects and indicating the explanation objects; a reader that reads types of the ID tags; and a control unit that changes explanation contents according to a combination of the explanation objects indicated by the ID tags read by the reader.

Claims

1. An ID-tag-based explanation system comprising:

a plurality of ID tags attached to a plurality of explanation objects for indicating the explanation objects;

a reader that reads a type of the ID tag; and

a control unit that changes explanation contents based on a combination of the explanation objects indicated by the ID tags read by said reader.

2. The ID-tag-based explanation system as defined in claim 1, wherein

said control unit comprises:

communication control means for instructing an operation of said reader;

storage means for storing the type of the ID tag read by said reader;

a plurality of ID tables, each storing therein a code indicating the type of the ID tag; and

program change means for grasping based on the types of the ID tags stored in said storage means and contents stored in said ID table the explanation objects presently collected and for changing the explanation contents according to the explanation objects presently collected.

3. The ID-tag-based explanation system as defined in claim 2, wherein

said program change means comprises:

comparison means for comparing the types of the ID tags stored in said storage means and the contents stored in said ID table to grasp the explanation objects presently collected; and

a program group storing a plurality of programs corresponding to a plurality of said explanation objects and selecting from said stored programs a program to be executed according to the explanation objects presently collected, informed by said comparison means.

4. The ID-tag-based explanation system as defined in claim 3, wherein

the program group (9) has a deeper layer program for the same explanation object and selects from the stored programs a program to be executed according to a number of the currently-collected explanation objects informed by said comparison means.

5. The ID-tag-based explanation system as defined in claim 1, wherein

said control unit comprises:

communication control means for instructing an operation of said reader;

storage means for storing the type of the ID tag read by said reader;

a plurality of ID tables, associated with said plurality of programs, each of said ID tables storing therein an ID code indicating the type of associated ID tag;

a program group stored in a memory, said program group including a plurality of programs associated with a plurality of said explanation objects;

program selection means for selecting a program to be executed from said program group;

table selection means for selecting an ID table corresponding to a program selected; and

comparison means for comparing the types of the ID tags stored in said storage means and an ID code stored in said ID table to find explanation objects present collected and for changing the explanation contents according to the combination of the ID tags presently collected;

said program group receiving the information of the comparison result by the comparison means and the program selected by the program selection means to change a program to be executed based on the received information.

6. The ID-tag-based explanation system as defined in claim 5, wherein

the reader, adapted to read contents of an ID tag in a communication area of said reader, reads under control of the communication control means, the contents of the ID tags being collected and brought in said area and sends the contents of the ID tags that have been read to the storage means.
