BACKGROUND OF THE INVENTION 
       [0001]    1. Technical Field 
         [0002]    The present invention relates to a system and method for specifying a product, and more particularly to a system and method for specifying or selecting a product by combining characteristics of other products. 
         [0003]    2. Description of Related Art 
         [0004]    In order to limit inventory and save store space many retailers such as furniture outlets, home improvement or department stores, etc., keep only a limited number of product types in their stores. For these products, a store may stock only representative items for each product offered. However, for seasonal or unpopular products, no stock may be on hand. In other cases, for example, furniture, while it may be possible to manufacture combinations of wood veneer and fabric that are not in the catalog, such combinations may not be offered as a choice to the shopper due to inflexible ordering methods. 
         [0005]    As a result of these shortcomings, consumers sometimes cannot find the item they need although similar items are available on the shelf. For example, a store may have jackets that are large and jackets that are small, and jackets that are red and jackets that are blue, but not of a desired combination, for example, a large red jacket. In another example a couch may be available in either a mahogany frame and maroon colored leather or a pine frame and peach colored leather in the store but a couch with mahogany frame and peach colored leather may not be in the store. 
         [0006]    Therefore, a need exists for a system and method for specifying an item using characteristics of other items. 
       SUMMARY OF THE INVENTION 
       [0007]    According to an embodiment of the present disclosure, a computer-implemented method for specifying the characteristics of a desired item includes specifying a plurality of items, each of which possesses at least one but not all characteristics of the desired item, selecting a subset of characteristics from each of said plurality of items, combining selected subsets of characteristics into a characterization of the desired item, and validating an availability of the desired item. 
         [0008]    According to an embodiment of the present disclosure, a computer system for specifying the characteristics of a desired item includes a memory storing computer readable code, and a processor for executing the computer readable code to perform a method. The method includes specifying a plurality of items, each of which possesses at least one but not all characteristics of the desired item, the computer system further comprising means for specifying the plurality of items, selecting a subset of characteristics from each of said plurality of items, the computer system further comprising a display for displaying the subset of characteristics and enabling user interaction to make a selection, combining selected subsets of characteristics into a characterization of the desired item, and validating an availability of the desired item.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0017]    According to an embodiment of the present disclosure, a method executable in a store setting allows a user to compose features of a target/desired product by selecting subsets of features from two or more other products that are retrieved from a catalog by associating a code or physical artifact corresponding to the other products. 
         [0018]    Embodiments of the present disclosure allow consumers or salespersons to specify the characteristics of the desired product starting from those of available products or from products with which the user is familiar. Using the same apparatus, the consumer can order the product with the desired characteristics in a desired quantity for home or store delivery, or buy or put them on hold at a different store, and have them picked up later, possibly by a different person, such as a friend. 
         [0019]    Since certain product characteristics are difficult to identify even by store clerks, especially for product lines with a short life time, a system or method according to an embodiment of the present disclosure may reduce the time needed to correctly identify the desired product and its availability. Further, a consumer may but the desired product once identified, if available now from a different store or a remote warehouse. 
         [0020]    Specifying the characteristics of the target product can be done by combining the characteristics of several observed products, one or more of which may be present in the store or present in the store catalog or information system. To make an informed decision, it is important for the customer to have direct access or a previous experience with the observed products that are used to compose the characteristics of the target product. The observed products used to compose the characteristics of the target product may be found in the same retail location as the target product. Therefore, the most appropriate location for the composition of product characteristics into the desired product is considered to be the retail location or store. In such a location, the composition of product characteristics is performed using a workstation or kiosk and zero or more mobile computing devices. 
         [0021]      FIG. 1  shows the block/flow diagram for specifying product characteristics of a target product by combining characteristics of observed products. At block  100  the method is initialized, e.g., a mobile device is provided to a user, and at block  101  a workstation screen is cleared. At block  102  the customer selects the source of information for a next observed product to be considered. Possible sources of observed product information are the World-Wide Web  103 , a store database  104 , products scanned using a mobile device  105  and products scanned using a scanner attached to the workstation  106 . For each observation, the characteristics of the observed product are introduced in the workstation at blocks  107 ,  108 ,  109  and  110 , respectively. These characteristics may be displayed as specifications of one or more items matching the characteristics of the source information. The display may be, for example, on a display screen of a mobile device. To avoid overloading the screen, one or more products, together with their characteristics, can be removed from the screen at block  111 . 
         [0022]    Each observation of a physical product can yield a number of characteristics. Typically, the user is only focusing on a limited set of characteristics. For example, the characteristic of color of an observed shirt may be important but the characteristics of texture, cloth or collar style may not be important. In block  112 , the characteristics of the observed product may be constrained by selection of only the desired characteristics. A number of different characteristics may be selected, see block  113 . Additionally, the characteristics of the observed product may be further logically qualified. For example, the user may choose the observed product to illustrate a product feature that is not desired, to illustrate a product feature that is only approximate, or illustrate a combination of products using logical operators, e.g., OR, XOR and the like. Both the constraint and the qualification of the characteristics of the observed product may be performed manually or automatically. For example, the system may be configured as a color selection station, in which case observations of products will be automatically constrained to the characteristic of color. The automatic constraint or qualification process may be configured via a set of system configurations or rules. The output of block  112  is a set of candidate assertions about the characteristics of the target product. For example, observation of a shirt—call it “Shirt A”—may yield the following assertions:
       COLOR LIKE RED   SIZE EQUALS LARGE   COLLAR EQUALS WIDE   FABRIC EQUALS COTTON       
 
         [0027]    Observation of a second shirt—call it “Shirt B”—may yield the following assertions:
       COLOR EQUALS BLUE   SIZE EQUALS LARGE   COLLAR NOT WIDE   FABRIC EQUALS SILK       
 
         [0032]    Subsequently, the user will select which of these assertions to apply to the target product. 
         [0033]    The observation process is repeated for each of the products the customer wishes to use as input for the characteristics of the target product. 
         [0034]    According to an exemplary embodiment of the present disclosure, in the iterative blocks, a product may be introduced using choices  105  or  106 , e.g., by scanning the product&#39;s tag using a scanner attached to a mobile device or directly to the workstation/kiosk. 
         [0035]    In block  114 , the assertions about the characteristics for the observed products introduced in a previous iteration are collected. Assertions about characteristics are grouped by type and compared. In the above example, there are four groups of assertions corresponding to the characteristics of COLOR, SIZE, COLLAR, and FABRIC. 
         [0036]    For each characteristic, the available assertions are merged, selected or left undetermined. Merged characteristics are ones that have been completely determined by the observation. In the example, the SIZE characteristic above is automatically determined to be LARGE, since both shirt A and shirt B are LARGE. The user may additionally determine characteristics at this point by viewing the assertions in a table displayed on a user interface (see  FIG. 4 ) and selecting the desired ones. For example, the user may select “COLOR LIKE RED”. The user may also choose to ignore observed assertions about the characteristics, for example, “COLLAR” may be set to take any value. Any unselected assertions may be treated by default as, for example, a logical disjunction (“OR”). For example, the system can infer that “FABRIC EQUALS SILK OR FABRIC EQUALS COTTON”. The logical function may be selected by the user. 
         [0037]    Additionally, the user may directly specify product characteristics that are not input from the observation process. 
         [0038]    In block  115 , the system performs a product check. The product check may include validating the availability of the product, which includes but is not limited to searching for existence or technical viability for made-to-order products, searching for availability in a remote location, for example, under conditions of location or convenience, and searching for desirability, for example, against a set of user preferences. 
         [0039]    If such one or more target products with the desired characteristics are found in block  115 , they are displayed in block  116 . One or more of these target products can be selected and ordered in block  117 , and the workstation screen is reset for the next customer or product in block  118 . 
         [0040]      FIG. 2  shows an exemplary action of scanning a tag  202  of store item  201  using the scanner  204  directly attached to the workstation/kiosk  203 . 
         [0041]      FIG. 3  shows an exemplary action of scanning of a tag  302  attached to an item  301 , e.g., a couch, using a scanner attached to mobile device  303 . The scanned information is transferred to workstation/kiosk  304  via a wireless technology, such as the IEEE 802.11 standard, using a wireless access point  305 . The scanned information is handled by a computer program implemented on the mobile device and it is either transferred to the workstation  304  immediately, if the user of the mobile device has the ownership of the screen of workstation  304 , or stored on the mobile device for transfer when the user acquires the ownership of the workstation screen  304 . 
         [0042]      FIG. 4  shows the workstation screen used to select the characteristics of the desired target product, which are in the rightmost column. The characteristics of the observed products introduced in blocks  107 - 110  are listed in individual columns, one characteristic per line. Each column corresponds to one of the observed products introduced previously. 
         [0043]    The characteristics are matched by type.  FIG. 5  shows the workstation screen for the case when exactly one product with the desired characteristics is found. The last line shows the product as available for pick-up from two different stores (X and Y) and for home delivery from the warehouse. If multiple products are found, each one may be displayed in a separate column, or in separate screens, all but one screen with an additional “next” button at the bottom. 
         [0044]      FIG. 6  shows the workstation screen used for ordering one of the desired products, selected using the screen in  FIG. 5 . In addition to commonly found fields, such as home address and payment information, the user may select to pick-up the product from one of the stores in the vicinity. Such a selection, if confirmed, guarantees the availability of the product for pick-up by the customer for the next NN hours (for example the next 24 hours). 
         [0045]    It is to be understood that the present invention may be implemented in various forms of hardware, software, firmware, special purpose processors, or a combination thereof. In one embodiment, the present invention may be implemented in software as an application program tangibly embodied on a program storage device. The application program may be uploaded to, and executed by, a machine comprising any suitable architecture. 
         [0046]    Referring to  FIG. 7 , according to an embodiment of the present invention, a computer system  701 , for example, the mobile device or workstation/kiosk, for facilitating an item selection based on characteristics selected from other items can comprise, inter alia, a central processing unit (CPU)  702 , a memory  703  and an input/output (I/O) interface  704 . The computer system  701  is generally coupled through the I/O interface  704  to a display  705  and various input devices  706  such as a mouse and keyboard. The support circuits can include circuits such as cache, power supplies, clock circuits, and communications bus. The memory  703  can include random access memory (RAM), read only memory (ROM), disk drive, tape drive, or a combination thereof. The present invention can be implemented as a routine  707  that is stored in memory  703  and executed by the CPU  702  to process the signal from the signal source  708 . As such, the computer system  701  is a general-purpose computer system that becomes a specific-purpose computer system when executing the routine  707  of the present invention. 
         [0047]    The computer platform  701  also includes an operating system and micro instruction code. The various processes and functions described herein may either be part of the micro instruction code, or part of the application program (or a combination thereof) which is executed via the operating system. In addition, various other peripheral devices may be connected to the computer platform such as an additional data storage device and a printing device. 
         [0048]    It is to be further understood that, because some of the constituent system components and methods depicted in the accompanying figures may be implemented in software, the actual connections between the system components (or the processes) may differ depending upon the manner in which the present invention is programmed. Given the teachings of the present invention provided herein, one of ordinary skill in the related art will be able to contemplate these and similar implementations or configurations of the present invention.
