Description:
BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates generally to systems and methods for resolving identification tags, and more particularly for variably resolved identification tags. 
   2. Discussion of Background Art 
   Universal Product Code (UPC) and RF-Identification (RFID) tags are a fixture in modern businesses. They are tools for enabling computers to associate a fixed set of information with each item carrying such tags. Such tags are often placed on goods for sale, so that a fixed set of product information, such as a model number and serial number, and a sales price, can be retrieved. 
   During use, a unique tag is scanned in some manner, interpreted, and a set of information corresponding to that unique tag is retrieved. Each time that unique tag is scanned the information retrieved is the same. In this way, for example, a store can consistently and automatically charge a certain predetermined price for each item for sale carrying one of these unique tags, so that the checkout person need not repetitively punch in the same price every time the same item is checked out. Similarly, during inventory management, a business can track it&#39;s capital equipment more efficiently by scanning such a tag, placed on an item, than by having an operator manually key in item information. It is this one-to-one correspondence between the tag and the item it represents which in the past has greatly improved the efficiency of many business enterprises. 
   Such a use, however beneficial, is also very rigid, especially in an increasingly mobile yet constantly connected modern culture. It is this very one-to-one correspondence, between the tag and the information the tag points to, which while useful, does not dynamically take into account the many variables affecting business enterprises and their customers. 
   In response to the concerns discussed above, what is needed is a system and method for resolving identification tags that overcomes the problems of the prior art. 
   SUMMARY OF THE INVENTION 
   The present invention is a system and method for identification tag resolution. The method of the present invention includes the elements of: identifying a set of attributes for a structure; assigning a tag to the structure; scanning the tag with a tag scanner; and modifying the structure&#39;s attributes, in response to scanning the tag. The structure&#39;s attributes can be modified in response to a value of a variety of variables, including a spatial variable, an orientational variable, a temporal variable, and a trust variable. 
   Also devices can be located proximate to the structure and, after a set of attributes identified for the device, the device&#39;s attributes can then be modified in response to scanning the tag. Simlarly, a set of attributes for the tag scanner can be identified and modified in response to scanning the tag. 
   Within the system of the present invention, are all means for effecting the method. These and other aspects of the invention will be recognized by those skilled in the art upon review of the detailed description, drawings, and claims set forth below.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
   The present invention&#39;s system and method for variable identification tag resolution, varies what actions are taken in response to a tag scan, even though the information retrieved from a tag itself can remain the same. This responsiveness is enabled by collecting information from sources other than the tag which then help resolve what specific information is retrieved and/or actions taken in response to a tag scan. Such a variably responsive result makes the present invention particularly advantageous over the prior art. 
     FIG. 1  is a dataflow diagram of one embodiment of a system  100  for variable identification tag resolution. “Tag resolution” is herein defined as the process of collecting and interpreting a variety of information, including tag information, in order to determine what actions are taken in response to a tag scan.  FIG. 2  is a data structure  200  used within one embodiment of the system  100 .  FIG. 3  is a flowchart of one embodiment of a method  300  for variable identification tag resolution.  FIGS. 1 ,  2 , and  3  are herein discussed together. 
   The system  100  includes a tag  102  to be read and/or scanned. The tag  102  is preferably associated with (i.e. assigned to) some sort of structure  103 . Structures&#39; are vary broadly defined to include: objects, devices, computers, rooms, buildings, geographic areas, data items, and so on. The tag can also take many different forms, including: a Universal Product Code (UPC) barcode tag, RF-Identification (RFID) tag, a virtual tag (i.e. such as a GPS location based tag), or some other sort of tag known to those skilled in the art. 
   The method  300  begins in step  302 , where a tag variables, values, and actions database  104  associates the tag  102  with the structure  103  and a set of variables  202 . The database  104  may be hosted in many ways, including by a networked central computer, or downloaded into a handheld computer. For example, the data structure  200  provides an example where “Tag-1”  204  is associated with variables “Variable-1”  206  through “Variable-N”  210 . The set of variables  202  can vary from tag to tag depending upon what the tags  102  are associated with. The set of variables  202  can be grouped in to a very wide variety of classes, including spatial, orientational, temporal, levels of trust, and so on. 
   Next, in step  304 , a set of values  212  is defined for each variable within the set of variables  202  and stored in the database  104 . For instance, if Variable- 1   206  is a spatial variable, then each Value  214  through  218  might correspond to a different store within chain of retail stores, a different room within a building, a different building within a city, and so on, including even every different GPS location on a planet. Similarly, if Variable- 2   208  is a orientational variable, then each Value  220  through  214  might correspond to a different location on a compass. And, if Variable-N  210  is a temporal variable, then each of its Values might correspond to a different times of a day, week, month, year, and so on. Those skilled in the art will recognize that many, many more variables and corresponding sets of values are possible depending upon how the present invention is used and what the tags  102  are associated with. 
   In step  306 , a set of actions  226  are associated with the tag variables values, either directly, combinationally, or permutationally, within the database  104 . To clarify, if a tag has as set of variables having a particular set of values, then the database  104  will associate with that tag, a particular set of actions. The particular set of actions may be directly dependent upon specific values of specific variable, or may be dependent upon some combination or permutation thereof. The data structure  200  in  FIG. 2 , for simplicity, only shows an embodiment where the actions are directly dependent upon specific values of specific variable. Those skilled in the art however, will know that an “N” dimensional matrix would more generally identify a particular set of actions to be associated with a tag having a particular set of variables having a particular set of values. 
   Those actions within the set of actions  226  are completely dependent upon how the present invention is used, however, the actions may include in no particular order: retrieving, modifying, displaying, downloading, printing, and/or storing information; varying service, trust, and/or permission levels; navigating to a web page; performing calculations; scheduling a room; generating a store coupon; and many, many others. 
   Next in step  308 , a tag scanner  106  scans one or more of the tags  102 . The scanner  106  may take a variety of forms, but is preferably included within a handheld computer, such as a cell phone or PDA. The scanner  106  may also include other devices and sensors capable of supplying values for the set of variables  202  associated with the tags  102 . Such other devices include: a spatial device, such as a GPS receiver; an orientational device, such as a compass or accelerometer; and a temporal device, such as a clock. Those skilled in the art will recognize many other devices which can also supply variable values. 
   In step  310 , a Variable Values, and Action Identification Module  108  receives the scanned tag information from the tag scanner  106 , and identifies in the database  104  variables, within the set of variables  202 , which are associated with the tags  102  scanned. The tag scanner  104  can communicate this information to the identification module  108  using a wireless network, a cellular network, a hardwired network, or any other network known to those skilled in the art. 
   In step  312 , the identification module  108  then identifies a current set of values, within the set of values  212 , for the variables associated with the scanned tags  102 . The values obtained by the identification module  108  may come from either the tag scanner  106  and its associated devices and sensors, and/or other informational resources  110 . The other resources  110  include databases and other device and sensor resources. 
   Then in step  314 , the identification module  108  identifies in the database  104  actions, within the set of actions  226 , which are associated with the variable values. In step  316 , one or more identified actions are effected by an action execution module  112  on the structure  103 . For example, if the structure is a room, the effected action may be to modify the rooms&#39; attributes, such as its schedule or environmental settings; or, if the structure is a printer, the effected action may be to modify the printer&#39;s attributes such as by enabling a unique set of printing permissions. 
   The execution module  112  also may effect one or more of the actions on the tag scanner  106 , in step  318 . For example, if the tag scanner  106  is a handheld computer, the effected action may be to modify the scanner&#39;s display attributes by displaying a web page. 
   Similarly, the execution module  112  may effect one or more of the actions on a device proximate to the structure  103 , in step  320 . Devices “proximate to” the tag scanner  106  are herein defined to include: a nearby computer, display, or printer; a second handheld computer; or in general, any device which preferably can readily be accessed or viewed by a user who uses the tag scanner  106  to scan one or more of the tags  102 . For example, if the structure is an item in a store for sale, the proximate device might be a nearby printer, and the effected action may be to modify the printer&#39;s attributes such that a coupon out corresponding to the item for sale is printed out. 
   Preferably, the database  104 , the identification module  106 , and the action execution module  112  are effected by a central server (not shown), perhaps covering a wide geographic region, such as an entire State or Country. The tags  102 , tag scanner  106  and other resources  110 , however, could be located anywhere, but are networked to the central server. 
   In summary, by scanning a tag, a cascade of events occur, including identifying variable values, which in turn affects what actions are executed. Should any one of the variable values change, a completely different set of actions may result, even though the tag scanned stays the same. 
   For illustrative purposes the following examples are given, however, those skilled in the art recognize that these examples are but a fraction of possible present invention implementations. 
   In a first example, a tag is affixed to a room. If the room has only one location, that is to say it is not mobile, an associated location variable will have only one possible value. A second variable may be temporal. Values of the temporal variable may range from the beginning to the end of a work day. Actions associated with the values of these two variables may be meetings scheduled within the room. Should a user scan this tag, the user would know and be able to schedule meetings for this room. 
   In a second example, a tag is affixed to a mobile printer. A first variable may be the printers model and serial number, indicating the printer&#39;s capabilities. A second variable may indicate the printer&#39;s location. A third variable may be time. Actions associated with the values of these three variables may include: permitting global access to the printer if the printer is located within a lobby of a building, but only between the hours of 8 AM to 5 PM; permitting only single user access to the printer if the printer is located within a specific office within the building, but at anytime during the day; and so on. Should a visitor scan this tag, the visitor would be able to print from the printer only if the printer was located in the lobby and then only between 8 AM and 5 PM. 
   In a third example, a tag is affixed to a good for sale in a retail store. A first variable may be the good&#39;s characteristics. A second variable may indicate which store the good is located. A third variable may be time. Actions associated with the values of these three variables may include: printing a 50% coupon if the good is located in store A during a week with the good is “on-sale;” or displaying information about the good on a handheld device if the good is located in store B and the good is not marked down for sale. Should a store customer scan this tag, the customer would receive a coupon if they are in store A during the on-sale period, but only information about the good if they are in store B. 
   While one or more embodiments of the present invention have been described, those skilled in the art will recognize that various modifications may be made. Variations upon and modifications to these embodiments are provided by the present invention, which is limited only by the following claims.
