Method and system for detecting the presence of a customer proximate to a wireless display tag
View Patent ↗A multiuse system for use with Wireless Display Tags (WDTs) includes, in one or more exemplary arrangements, techniques for automatically maintaining synchronicity between pricing data for a product and advertising, marketing or promotional data associated with that product, and for detecting the proximity and location of a customer within a category of goods displayed within a managed environment. A messaging format suitable for such low power operation among a large number of peers is also disclosed, as is a technique for integrating a plurality of smaller displays to yield a single large display. An access point capable of serving as a communications hub within such a network, while at the same time offering visual and audio surveillance capabilities, is also disclosed.
1. A method for detecting the presence of a customer proximate to a wireless display tag comprising:
providing a plurality of wireless display tags in a predetermined configuration within a space wherein the location of each wireless display tag is known;
detecting, at each WDT within a proximate distance from a consumer, a signal from a transmitting device associated with the consumer;
determining relative signal strengths for each detected signal; and
comparing the relative signal strengths with the known location of the associated wireless display tags to determine the location of the consumer.
2. The method of claim 1 further comprising transmitting one of information for a shopping trip and marketing information to the transmitting device of the consumer based on the location of the consumer.
3. A system for detecting the presence of a customer proximate to a wireless display tag comprising:
a plurality of wireless display tags arranged in a predetermined configuration within a space wherein the location of each wireless display tag is known with respect to product placement;
logic for detecting, at each WDT within a proximate distance from a consumer, a signal from a transmitting device associated with the consumer;
logic for determining the relative signal strengths for each detected signal and; comparison logic for comparing the relative signal strengths with the known location of the associated wireless display tags to determine the location of the consumer.
4. The system of claim 3 wherein the logic for determining relative signal strength is in a host computer.
5. The system of claim 3 wherein the comparison logic is in a host computer.
6. The system of claim 3 further comprising a central receiving station that transmits one of information for a shopping trip and marketing information to the transmitting device of the consumer based on the location of the consumer.
