Abstract

Portable handheld transceiver-enabled devices (e.g., PDA or cell phone) and an enterprise system that stores and maintains a digital map and database to enable customers using the portable devices within a store to access information about the location of products in the store and their availability. Several fixed transceivers are installed throughout a store and portable transceiver-enabled handheld devices used by customers within the store communicate within the store. Portable handheld transceiver-enabled devices communicate with fixed transceivers and download the locations and available quantities of desired product. Customers can use portable devices to obtain the shortest walking route within a store to obtain a desired product based on fixed transceiver proximity to portable devices. Customer can also search the store database for the exact location of items within a store using the portable devices.

Claims

1. An in-store shopping system, comprising:

a store computer system configured to maintain digital map data, store product information in a database and permit customers using portable RF transceiver-enabled devices operating within a store to access said digital map data and information regarding a location of a product in the store and an availability of the product; and

more than one fixed RF transceiver and a plurality of RFID tags installed throughout the store on a plurality of products, and installed within said portable RF transceiver-enabled devices, wherein the plurality of RFID tags communicate within the store with portable RF transceiver-enabled handheld devices utilized by customers and the more than one fixed RF transceiver can communicate within the store with portable RF transceiver-enabled handheld devices used by customers.

2. The system of claim 1 further comprising at least one portable handheld RF transceiver-enabled device in communication with at least one of the more than one fixed RF transceivers and the plurality of RFID tags associated with the store computer system.

3. The system of claim 1, wherein said store computer system includes a module that permits is to enable customers using the portable RF transceiver-enabled devices within a store to access information about the location of products in the store and their availability.

4. The system of claim 1 further comprising a module configured to permit portable handheld RF transceiver-enabled devices to communicate with the fixed RF transceivers and RFID tags on products or shelves and download the locations and available quantities of a desired product from said store computer system.

5. The system of claim 1 further comprising a module configured to permit a user of the at least one portable handheld RF transceiver-enabled devices to obtain a shortest walking route within the store to obtain a desired product based on a proximity of a plurality of said RFID tags to the portable handheld RF transceiver-enabled devices.

6. The system of claim 1 further comprising a module configured to permit a user of a portable handheld RF transceiver-enabled device to search the store computer system for the exact location of items within the store.

7. The system of claim 1, wherein the portable handheld RF transceiver-enabled device is configured to permit customers using the portable handheld RF transceiver-enabled devices within a store to access information about the location of products in the store and their availability.

8. The system of claim 1, wherein the portable handheld transceiver-enabled device is configured to permit portable handheld RF transceiver-enabled deices to communicate with the fixed RF transceivers and RFID tags on products or shelves and download the locations and available quantities of desired product from said store computer system.

9. The system of claim 1, wherein the portable handheld RF transceiver-enabled device is configured to permit a user of the at least one portable handheld RF transceiver-enabled devices to obtain a shortest walking route within the store to obtain a desired product based on a proximity of a plurality of said RFID tags proximity to the portable handheld RF transceiver-enabled devices.

10. The system of claim 1, wherein the portable handheld RF transceiver-enabled device is configured to permit a user of a portable handheld RF transceiver-enabled device to search the store computer system for the exact location of items within the store.

11. A method of determining a product status by a store computer system including short range RF communications hardware, comprising the steps of:

a store computer system wirelessly receiving from a handheld device, a request for product information including a location of products within the store;

dynamically determining via the store computer system, the location of the products within the store based on an RFID tag;

dynamically determining via the store computer system, the location of the handheld device within the store based on an RFID tag associated with the handheld device; and

the store computer system wirelessly transmitting product information including the location of a product to the handheld device.

12. The method of claim 11 further comprising the steps of:

graphically depicting the product information sent to the handheld device on a map of a floor plan of the store; and

transmitting the product information to the handheld device from the store computer system for rendering on a display screen associated with the handheld device.

13. The method of claim 11 wherein product location information sent to the handheld device includes directions regarding the shortest route through the store to a location of the product based on the location of the product and a location of the handheld device.

14. The method of claim 11 wherein the product location information sent to the handheld device is depicted on a map of a floor plan of the store, wherein the floor plan is further rendered on a display screen associated with the handheld device.

15. The method of claim 11 wherein product information sent to the handheld device includes directions regarding a shortest route through the store to the in-store location of the product.

16. A method of determining product status and in-store location, comprising the steps of:

wirelessly transmitting from a handheld device to a store computer system via short range RF communications, a request for product information associated with a product, wherein the product information includes an in-store location of the product;

wirelessly receiving at the store computer system, the request for product information including the in-store location of the product with respect to the handheld device;

determining, via the store computer system, the in-store location of the product based on an RFID tag associated with the product;

determining, via the store computer system, a location of a user of the handheld device within the store based on an RFID tag associated with the handheld device; and

wirelessly transmitting from the store computer system to the handheld device, the product information, wherein the product information includes the in-store location of the product.

17. The method of claim 16 further comprising the steps of:

graphically depicting on a floor plan of the store, the in-store location information; and

displaying the floor plan with the in-store location information on a display screen associated with the handheld device.

18. The method of claim 16 further comprising the steps of:

determining via the store computer system, the location of the handheld device within the store before determining the in-store location of the product; and

transmitting directions regarding a shortest route through the store to the in-store location of the product, based on the location of the handheld device within the store.

19. The method of claim 18, wherein the product location information sent to the handheld device is depicted on a map of a floor plan of the store, wherein the map is also transmitted to the handheld device from the store computer system and rendered on a display screen associated with the handheld device.
