Abstract

In a store information display system comprising a mobile unit terminal connected to the communication network, a store information control apparatus connected to the communication network, a receiving means for receiving positioning data of the mobile unit terminal and retrieval conditions from the mobile unit terminal, a store information retrieval means for establishing a retrieval area in a direction of travel of the mobile unit terminal and performing retrieval of stores information within the retrieval area, a retrieval area adjusting means for adjusting dimensions of the retrieval area, and a stores information transmitting means for transmitting stores information founded by the store information retrieval means to the mobile unit terminal, are provided.

Claims

1. A store information display system comprising:

a communication network;

a mobile unit terminal, connected to said communication network, having position detection means which detects position thereof;

a store information control apparatus, connected to said communication network;

a receiving means, provided in said store information control apparatus, for receiving positioning data detected by said position detection means and retrieval conditions with respect to a request of a retrieval of store information from said mobile unit terminal;

a store information retrieval means, provided in said store information control apparatus, for establishing a retrieval area in a direction of travel of said mobile unit terminal based on said received positioning data of said mobile unit terminal and said retrieval conditions, and performing retrieval of stores information within said retrieval area;

a retrieval area adjusting means, provided in said store information retrieval means, for adjusting dimensions of said retrieval area in accordance with retrieval conditions received from said mobile unit terminal; and

a stores information transmitting means, provided in said store information control apparatus, for transmitting stores information founded by said store information retrieval means to said mobile unit terminal.

2. The store information display system according to claim 1, wherein said retrieval area is a region surrounded by a circle.

3. The store information display system according to claim 1, wherein a center of said retrieval area is established based on a traveling speed of said mobile unit terminal.

4. The store information display system according to claim 1, wherein a center of said retrieval area is a location at which said mobile unit terminal has moved a prescribed distance along a path of movement thereof after receiving a request for store information retrieval from said mobile unit terminal.

5. The store information display system according to claim 1, wherein said retrieval conditions includes upper limit value which limits a number of store information displayed on said mobile unit terminal, said retrieval area adjusting means adjusting said dimensions of said retrieval area in accordance with said upper limit value and a number of store information founded by last retrieval.

6. The store information display system according to claim 1, wherein said retrieval conditions includes lower limit value which limits a number of store information displayed on said mobile unit terminal, said retrieval area adjusting means adjusting said dimensions of said retrieval area in accordance with said lower limit value and a number of store information founded by last retrieval.

7. A display method of a store information using a store information display system comprising a communication network, a mobile unit terminal, connected to said communication network, having position detection means which detects position thereof, and a store information control apparatus connected to said communication network, said method comprising the steps of:

receiving a request for store information retrieval, positioning data detected by said position detection means and retrieval conditions with respect to said retrieval of store information from said mobile unit terminal;

calculating a traveling speed of said mobile unit terminal;

calculating a location to which said mobile unit terminal has moved by a prescribed distance along a path of movement thereof after receiving said request for store information retrieval from said mobile unit terminal;

establishing a retrieval area in a direction of travel of said mobile unit terminal based on said received positioning data of said mobile unit terminal and said retrieval conditions;

performing retrieval of stores information within said retrieval area;

adjusting dimensions of said retrieval area in accordance with retrieval conditions received from said mobile unit terminal and retrieval results obtained by last retrieval; and

transmitting stores information founded by said retrieval to said mobile unit terminal.
