BACKGROUND 
     Field of the Invention 
       [0001]    The subject matter described herein relates generally to real-time locating system. More specifically, the present disclosure is related to locating a shopping cart within a store and analyzing a shopping behavior of a shopper based on a pattern identified by tracking the movement of a shopping cart. In addition, the present disclosure provides a shopping cart that is suitable for moving in a confined space. 
       Description of Related Art 
       [0002]    Traditional shopping carts impose several issues and problems. Traditional shopping carts are typically built to provide a large receptacle to retain as many merchandises as possible. They are too bulky for large retail locations, such as a shopping mall, that have escalators and stairs. 
         [0003]    In order to analyze the customer&#39;s need and to improve the shopping experience, it is necessary to analyze a pattern of the shoppers in a store. Reducing a foot traffic or placing the merchandise in an optimized fashion can not only increase sales, but also can prevent the loss of shoppers&#39; visits due to fatigue and unpleasant shopping experience. Macro and micro identification of the shoppers&#39; foot traffic and traffic patterns can help determine an optimized placement of merchandise and control traffic of the shoppers. Among other benefits, the present disclosure may help manage the customer traffic better and manage the control of the shopping experience. 
         [0004]    Therefore, what is needed is a shopping cart that provides more freedom of movement within a crowded and narrow space. There also is a need to provide a system and method that tracks movement of a shopper to analyze the shopper&#39;s behavior and purchase pattern. Such a system and method can improve the shopping experience, in turn increase the traffic and the revenue for a store.

         [0059]    In another embodiment, the communication coverage may exclude certain locations within the store area, when such locations have limited access to the users. 
         [0060]    Once the one or more reference points are distributed within the store area to define the communication coverage, the RF module of the shopping cart may be identified by the one or more reference points as it moves within the covered store area. In turn, the central computing unit may identify the location of the shopping cart within the store area. 
         [0061]    In one embodiment, the location of the shopping cart may be tracked in relation to time. The location of the shopping cart may be identified with a time stamp at that location. The time may include hours, minutes, seconds, days, years, months, and the like. The identified location of the shopping cart may be logged at the storage unit for further analysis. In some embodiments, the location of the shopping cart and its time may be identified at the specific location. For example, the central computing unit may identify an initial time of entrance to an aisle (a location), an exit time out of the aisle, thus a duration of visit to the aisle. The one or more reference points, the floor reference point, and the checkout terminal reference point may be utilized for tracking the shopping cart visiting the specific location and any other locations within the store area. 
         [0062]    In another embodiment, the central computing unit may identify a duration of the shopping cart at a location within the store area. The duration may be determined based on the lapsed time of the shopping cart at a certain location or within its vicinity. 
         [0063]    In yet another embodiment, the central computing unit may identify a trail or a path of the shopping cart&#39;s movement while the shopping cart is in use by the user. The trail may provide time, location, and a duration of the shopping cart in use. For example, the trail may include a first location the shopping cart was positioned, a first duration at a certain specific location, a second location once the shopping cart moves, a second duration at a certain specific location, and so on. 
         [0064]    The time, location, duration, and trail of the shopping cart collected by the central computing unit may be referred to as a behavior data. The behavior data may be further analyzed to identify a shopping behavior or a pattern of the shopping cart, hence a behavior of the user at the store area. The behavior data may be analyzed to identify certain correlations, causal relations, and tendency among the collected behavior data. 
         [0065]    The item being picked up by the user to the shopping cart may be identified by the sensor equipped by the shopping cart. The type of the item may be identified. Similarly, the type of the item may be identified by the optical scanner. In some embodiments, the shopping cart may be equipped with a sensor that detects an item being retained by the shopping cart. 
         [0066]    In one embodiment, a plurality of items at the store area may be categorized into types. The type may be categorized based on various criteria, such as fashion, grocery, sports, and the like. The storage unit may contain an item-to-type list preconfigured at the storage unit. 
         [0067]    In another embodiment, a plurality of items at the store area may be categorized into types based on the location where the item is picked up. The specific locations and/or the location of interest may be linked to items being carried within the specific locations and/or the location of interest. In an exemplary embodiment, the sensor may detect that an item is picked up. The location of the shopping cart may be identified to determine the type of the picked up item based on the types of items linked at that location. The links between the items and the locations may be preconfigured at the storage unit. 
         [0068]    The behavior data may further comprise the item type or its identification for further analysis of the shopping behavior. A purchase pattern may be determined by the central computing unit based on the behavior data. In one embodiment, the purchase pattern of the type of items may be identified with regards to time, duration, and trail. While the user picks up multiple items, the central computing unit may identify when the first item was placed at the shopping cart (time) and how long it took to place the first item (duration). The second item&#39;s pick up time and duration-to-pick-up can also be identified in a similar fashion. As such, the purchase pattern may include the trail of the user picking up the multiple items, for example from the first item to the second item. The determined purchase pattern can be utilized to study the behavior of the shoppers. For example, based on the purchase pattern, the multiple items can be placed within the store area strategically to improve the shopping experience. For example, the first item and the second item may be often bought by multiple users over time during a single visit to the store. Thus, the purchase pattern may suggest that the first item and the second item may be placed closed to one another. 
         [0069]    In some embodiments, the checkout terminal reference point may be utilized as an exit point. The behavior data may include the time the shopping cart passed through the checkout terminal reference point to determine the duration of the entire shopping experience at the store area. The beginning of the shopping experience may be determined by either identifying the initial activation of the shopping cart or the time the shopping cart is registered by the reference point at an entrance to the store area. In some embodiments, the checkout terminal reference point may be utilized to measure the duration it takes to transact the items at the checkout terminal. In a further embodiment, the checkout terminal reference point may be utilized to prevent loss at the store by identifying any shopping carts that does pass through the checkout terminal. 
         [0070]    Further analysis of the behavior data may suggest various shopping behaviors of the user. Different applications of the behavior data analysis may result in an identification of various shopping behaviors. The behavior data, the shopping behavior, and its applications may be provided by the central computing unit in a report. The report may be provided to a store admin or personnel. 
         [0071]    In one embodiment, the shopping behavior may determine a traffic amount at a location within the store area. The central computing unit may determine how crowded it gets at a certain location at a certain time. Tracking the locations of multiple shopping carts at a certain location may provide a number of shopping carts at that location at a given time. The central computing unit may rank the locations within the store area based on the traffic amount to identify a pattern. For example, during a Christmas season, stores that carry Christmas ornaments may have a larger traffic in comparison to during the summer. Similarly, other patterns/shopping behaviors may be identified by determining the traffic amount. 
         [0072]    In another embodiment, the shopping behavior may determine a frequency of visit to a location within the store area. The central computing unit may observe and identify the number of visits during a certain duration to determine how often the users visit a certain location. Based on the identified frequency of visit, the stores and/or the aisles may be placed within the store area strategically to improve the shopping experience. For example, the most frequently visited stores may be placed near the entrance of the store area in order to prevent the store from being overcrowded. 
         [0073]    In yet another embodiment, the shopping behavior determined based on the behavior data and the purchase pattern may suggest a strategic item placement within the store area. The central computing unit may identify the purchase pattern of a multiple items. For example, the purchase pattern may include the trail of the user picking up the multiple items. Based on the trail of the purchase pattern involving a certain types of items, the central computing unit may recommend item placements. For example, if many users tend to frequently purchase the first item and the second item consecutively, the central computing unit may recommend to place the first item and the second item close to one another. 
         [0074]    The central computing unit may utilize the user profile to determine the shopping behavior. In some embodiments, the central computing unit may receive user profile about the user using the shopping cart. The user profile may include, but not limited to, age, occupation, gender, income level, and the like. Such user profile information may be correlated with the behavior data to determine a shopping behavior commonly shared by the users having a common user profile. In an exemplary embodiment, users, in an age group between  15  to  25  and gender as male, may have a tendency/pattern to shop most frequently at a location such as sports, gaming, or electronics. Based on such identified shopping behavior in relation to a user profile, items, stores, and/or aisles may be paired. 
         [0075]    Turning now to  FIG. 1 ,  FIG. 1  illustrates an exemplary embodiment of the shopping cart  100 . The shopping cart  100  comprises a pole  102  and a base  106 .

The system  200  comprises a plurality of reference points  202 - 1   202 - 2   202 - 3  (collectively referred to as  202 ). The plurality of reference points  202  are in communication with the central computing unit  204 . The central computing unit  204  receives data/signal from the plurality of reference points  202  over a network. The central computing unit  204  may comprise one or more processors and may be in communication with the storage unit. The system  200  further comprises a plurality of shopping carts  206 - 1   206 - 2   206 - 3  (collectively referred to as  206 ). Each of the plurality of shopping carts  206  are equipped with the RF module. Thus, each of the plurality of shopping carts  206  are in communication with the plurality of reference points  202 . The location of the RF module is identified by the central computing unit  204  via the communication network shown in the system  200 . In turn, locations of the plurality of shopping carts  206  are identifiable via the RF module. 
         [0077]      FIG. 3  illustrates an exemplary embodiment of the reference point placements in multiple aisles. The store area  300  comprises the multiple aisles, aisle  1   302 , aisle  2   304 , aisle  3   306 , aisle  4   308 , aisle  5   310 , and aisle  6   312 . The reference point is placed at each of the multiple aisles to identify locations of the shopping carts, for example cart  1   326  and cart  2   328 , within the multiple aisles. In this exemplary embodiment, the reference point is assigned to each of the multiple aisles, namely the reference point  1   314 , the reference point  2   316 , the reference point  3   318 , the reference point  4   320 , the reference point  5   322 , and the reference point  6   324 . Each of the reference points are in communication with the RF module, and monitors and detects the RF module entering into the multiple aisles. The reference point  1   314  detects the shopping cart  1   326  entering aisle  1   302 . The central computing unit may receive the location and the time of entrance to aisle  1   302  by the shopping cart  1   326 , by communicating with reference point  1   314 . In this example, reference point  1   314  is assigned to monitor activities in aisle  1   302 . Similarly, reference point  2   316  may monitor and detect the movement of shopping cart  2   328  in aisle  2   304 . 
         [0078]      FIG. 4  illustrates an exemplary embodiment of the reference point placements in multiple stores. The store area  400  comprises the multiple stores ( 402 ,  404 ,  406 , and  408 ). Each of the multiple stores are equipped with a reference point ( 410 ,  412 ,  414 , and  416 ). The reference point may identify the shopping cart entering the store and exiting the store. In this exemplary embodiment, the behavior data may comprise time of entrance to the store, time of exit from the store, duration of stay in the store, and trails of the shopping cart&#39;s movement among the multiple stores  402   404   406  and  408 . Similar to the reference point placements in aisles within the store, each of the multiple stores may be paired with the reference points ( 410 ,  412 ,  414 , and  416 ). Each of the reference points may monitor and detect movement of the shopping cart as it enters the multiple stores. Thereby, location of the shopping cart can be monitored at the multiple stores level within the store area. This allows more granular analysis of the shopping cart&#39;s location within the store area. 
         [0079]      FIG. 5  illustrates a flowchart describing an exemplary method for determining a shopping behavior. The method may being with the central computing unit identifying the positions of the one or more reference points  502  placed within the store area. With the one or more reference points placed in the store area, the central computing unit may define the RF communication coverage within the store area  504 . Number of the one or more reference points may cover the specific locations and/or the locations of interest. The central computing unit further assigns the specific locations and the locations of interest  506  among the one or more reference points placed in the store area. At step  508 , the location of the shopping cart is received from the RF module via a corresponding reference point. Further at step  510 , the behavior data corresponding to the shopping cart is analyzed by the central computing unit. The behavior data may include location, time, duration, and trail. Finally, the shopping behavior/pattern may be determined  512  by the central computing unit based on the behavior data. 
         [0080]      FIG. 6  illustrates a flowchart describing an exemplary method for determining the purchase pattern. The type of a first item being placed in the shopping cart  602  is identified by the central computing unit. Similarly, the type of a second item is identified at  606 . The behavior data of the shopping cart in relation to the first item is identified  604  by the central computing unit. The behavior data of the shopping cart in relation to the second item is also identified at  608 . Once the types and the behavior data of both the first item and the second item are identified, the central computing unit may determine the purchase pattern of the items by analyzing relations between the types and behavior data  610 . 
         [0081]      FIG. 7  illustrates a flowchart describing an exemplary method for recommending item placement. The central computing unit may receive the types of multiple items being retained by the shopping cart  702 . At  704 , the behavior data related to the multiple items, for example the trail of the shopping cart in the course of picking up the multiple items, is received by the central computing unit. The central computing unit further identifies the tendency/pattern among the received behavior data and the types of the multiple items  706 . Finally, the central computing unit recommends the placement of the multiple items based on the identified tendency/pattern  708 . 
         [0082]      FIG. 8  illustrates a flowchart describing an exemplary method for correlating user profile with the behavior data. The central computing unit receives the user profile of the user using the shopping cart  802 . Further, the central computing unit receives the behavior data of the shopping cart  804 . The received user profile and the behavior data of the shopping cart is correlated  806  to determine the shopping behavior in relation to the correlation  808 .
