     DESCRIPTION OF EXEMPLARY EMBODIMENTS 
     Conventional shopping assistants generally require interaction with a relatively small hand held device. Shopping frequently necessitates the physical movement of items from a shelf to a cart or from a shelf for closer examination. Holding the mobile device requires a hand, leaving only one hand free. While voice commands or another form of audio recognition might resolve some of the manual difficulties that can occur when using a mobile shopping assistant and free up both hands for shopping, voice commands may confuse others in the vicinity of the user. A young parent shopping with one or more small children, for example, might find it difficult to distinguish vocal interaction with the children from the vocal interaction with the shopping assistant. 
     In some embodiments, the disclosed subject matter encompasses technology that recognizes subvocal, i.e., inaudible, commands using external sensors configured to detect muscle and/or nerve impulses in the proximity to the vocal tract. Subvocal sensors may take on various physical implementations including cosmetically “transparent” implementations in which the sensor(s) have the appearance of jewelry. 
     Subvocal commands could be processed by a subvocal module in the shopping assistant application to request or in response to audio guided shopping directions. Persons in proximity to the user may be unaware of the command and response exchange, because commands would be subvocal and response and directions may be provided through an earpiece. Vocal conversation having an audio component would be ignored by a subvocal module of the shopping assistant. The user may carry on a conversation with people nearby and continue in a guided shopping venue. The young parent could care for unruly young children providing vocal guidance and physical assistance all the while carrying on a subvocal command and response dialogue with a shopping assistant that is guiding her to items she wishes to purchase. 
     To efficiently shop in a retail store, an end user or shopper must either know where items are located via past experience, figure out the layout of the store, or request help. This may be complicated by having numerous items to purchase, and thereby, compounding the time to locate the items. When shoppers can&#39;t find an item, they frequently give up and leave the store. Disclosed subject matter includes subject matter to compare the store&#39;s planogram or other type of data structure that includes item location information, to an end user&#39;s ESL on a mobile device. The disclosed method may re-order the ESL based on the store location of the ESL items as indicated in the planogram location, e.g., aisle by aisle, and area by area, so as to facilitate the end user&#39;s efficient movement through the store to acquire the applicable items. Additionally, a store map of aisle and area location could be provided to the mobile device as an overall guide to the layout of the store. It should be noted that, although numerous features disclosed herein refer to an ESL, the use of an ESL in connection with some aspects of the disclosed subject matter is not meant to imply or require an ESL stored on all mobile devices that are enabled to perform some or all of the functionality disclosed herein. Subvocal functionality, for example, may be achieved with a mobile device on which no ESL is stored. 
     The disclosed subject matter improves the shopping experience of the shopper. It provides them the item location information in an ordered fashion and removes the need for the shopper or end user to look to maps, kiosks, signage, or store clerks for assistance in locating items and can be particularly important during seasonal changeovers or other reorganization of store layouts. 
     In a first aspect, the disclosed subject matter encompasses a method for providing shopping assistance to a user within a store. The method includes enabling a mobile device to detect a subvocal message (SVM) from the user where the SVM corresponds to an item in the store. The mobile device is enabled to transmit a request in response to detecting the SVM. The request includes information indicating the item and/or aspect(s) or characteristic(s) of the item. The mobile device is further enabled to receive a reply that includes information responsive to the request and provide the responsive information to the user. 
     In some embodiments, the request may include a request for position information indicative of a position of the item in the store, a request for price information indicative of a price of the item in the store, and/or a request for inventory information indicative of an inventory of the item in the store. Enabling the mobile device to detect the SVM may include enabling the mobile device to detect the message via a subvocal sensor coupled to the user. The subvocal sensor may be in contact with the user in proximity to a vocal cord of the user, e.g., in contact with the user&#39;s neck or throat area. The subvocal sensor may be connected to the mobile device by wire or wirelessly. The subvocal sensor may have a decorative appearance such as a necklace or some other suitable item of jewelry. 
     Embodiments of the mobile device may be able to distinguish between a vocal message and an SVM. In these embodiments, the mobile device may be enabled to ignore vocal messages while processing SVMs, ignore SVMs while processing vocal messages, and/or independently process SVMs and vocal messages simultaneously. The SVM may indicate various aspects of a store item, including, as an example, an alphanumeric sequence corresponding to a universal product code (UPC) or other form of scannable code. In some embodiments, the reply information may include information retrieved from a store planogram. The mobile device may be detected and registered upon entering the store. Information promoting related items may be provided to the mobile device. 
     In another aspect, a disclosed mobile device, suitable for use by a user within a store, includes an SVM module, a transmitter, a receiver, and an output device. The SVM module detects an SVM from the user. The SVM includes data indicating an item in the store or an aspect or characteristic of the item. The transmitter is configured to transmit a request indicating the item in response to detecting the SVM. The receiver is configured to receive a reply having information that is responsive to the request. The output device is configured to provide the responsive information to the user. The mobile device may be configured to detect the SVM via a subvocal sensor coupled to the user. In some implementations, the subvocal sensor may be in contact with the user in proximity to the user&#39;s vocal cords. The mobile device may include a wired and/or wireless interface for communicating with the subvocal sensor. The SVM module may be configured to differentiate between SVMs and vocal messages. In these embodiments, the SVM module may be configured to process SVMs and ignore vocal messages. 
     In another aspect, a disclosed computer readable storage medium having embedded computer useable instructions including instructions for providing shopping assistance to a user within a store, includes instructions to detect an SVM from the user, transmit a request in response to detecting the SVM, receive a reply, and provide the responsive information to the user. The message may correspond to an item in the store and the request may include information indicative of the item. The reply includes information responsive to the request. 
     In other aspects that may be implemented with or without regard to the subvocal functionality, the disclosed subject matter encompasses the application of a store planogram to an ESL on a mobile device to provide guidance to item locations in the applicable store. The disclosed subject matter provides the end user with a detailed plan for a recommended sequence of locating the items within the store. The detailed plan may be provided as text (e.g., by aisle and area) or as pictures illustrating the items and locations in the aisle and area. 
     Disclosed methods, systems, devices, and software enable locating a user or shopper with respect to items in a store, and thereby, locating the position of the user in the store. In one embodiment, the disclosed subject matter identifies the general location of the user in a store by exposing a store planogram (i.e., a database or data structure that includes information from which locations, maps, or diagrams of items, fixtures, and/or facilities within the store can be generated) to a mobile or wireless device of the user. The planogram contains data that indicates the location of the store items and this information may be used to identify the location of the user within the store. The mobile device may be a network aware device capable of wirelessly communicating via an Internet protocol (IP) or other type of packet-switched network. The mobile device may further include cellular telephony functionality. The mobile device may have processing capacity, display resources, and keypad support sufficient to execute applications such as Web browsers and other applications. In embodiments suitable for use in retail shopping applications, the mobile device may further include a camera or other type of image capture device and the user may cause the mobile device to interact with a store item by scanning or entering bar codes, UPC codes, pictures, etc., of the store item. The user may convey information pertaining to a store item by removing or checking off the store item from an ESL saved in a memory or other type of storage media of the mobile device. The disclosed subject matter permits a determination of the user&#39;s location within the store and facilitates opportunities for providing targeted promotion and services to the user based on the user&#39;s location. Currently, users generally locate themselves within a store via applicable signage or by requesting help from store employees. In addition to signage, stores often use high cost systems such as cameras and clerks to locate or assist users with questions pertaining to location or to otherwise provide additional promotions or services to users. 
     In one embodiment, the disclosed subject matter resolves user location within a store by making the store&#39;s planogram or schematic accessible to the user&#39;s mobile or wireless device. In one embodiment, an application, referred to herein as a shopping assistant, is provided for use with the user&#39;s mobile phone. The shopping assistant is operable to provide and maintain an ESL and may include hardware and/or software facilities to recognize store items by bar code, UPC code, pictures, and the like. When a shopping event occurs, such as the mobile device interacting with a store item using the phone or the user moving an item from the ESL to a shopping cart, the shopping assistant may identify the location of the user from the store item involved in the shopping event and the item placement information within the store&#39;s planogram or schematic. As the user moves through the store and selects items, a location trail for the user may be developed. This location trail, or item selection trail, identifies the approximate location of the user. A more specific location may be established by having the user scan/enter multiple different items in proximity to the user. This procedure may establish the location of the user within a few feet. Users can request their location and, if the location is known because of recent actions in the selection trail, then a response can be provided. If the age of the selection trail exceeds a specified threshold, a request could be transmitted to the mobile device for display. The request could prompt the user to use the mobile device to scan, enter, or otherwise interact with some nearby store items in order to refine the location. 
     The disclosed subject matter provides the store and user with an estimate of the user&#39;s physical location within the store. The estimate may be a sufficiently accurate location for a variety of purposes, e.g., promoting items that are known to be close to the user&#39;s current location and guiding the user to items that are on the user&#39;s ESL. The estimate of the user&#39;s location derived in this manner is generally preferable to estimating the user&#39;s position using a global positioning system (GPS), which may be unreliable or non-operational in stores because of metal roofs and structures that attenuate the signals necessary for precise location using GPS. In one embodiment, the user may be permitted to opt-in or to opt-out of the location estimation system. The disclosed subject matter benefits the store by providing a mechanism for location specific promotion and service to the user. Through one embodiment, the store would know where a user is in the store, and consequently, the store may better serve the specific needs and wants of the user while at the same time having minimal or no infrastructure costs associated with implementation of the disclosed subject matter (commonly referred to as chain math). 
     Because current retail promotion and inventory management is predicated on past behaviors, i.e., what has been purchased by the customer as opposed to what is planned to be purchased by the customer, current inventory planning is generally a best guess based on tracked behaviors of population groups. Additionally, there is little, if any personalization to the current methods of advertising via circulars, or broadcast advertisements. The closest method may be direct mail to an individual, but this is a costly technique. 
     The disclosed subject matter includes a shopping assistant/agent which is computer and mobile phone based and which has access to a retail organization portal. An end user or customer may prepare an ESL on both the computer and mobile phone which are kept synchronized. End users may selectively grant retail organizations access to their ESLs. End users may grant ESL access to retail organizations either anonymously or “personally,” i.e., in such a way that the retail organization is aware of the user&#39;s identity. Retail organizations gain access to the ESL through the portal, in exchange for promotion information, coupons, store stock item detail, loyalty program features, additional services, discounts, and the like. Access to the end user&#39;s ESL provides a forward look into retail demand based on the specific intention of the end users who provide their ESLs. The lists allow retailers to more accurately anticipate demand, and consequently, plan inventory and promotions based on intended purchases rather than based on conventional statistical methods that rely entirely or substantially entirely on historical purchase data. Additional accuracy may be achieved by monitoring items identified on ESLs against items actually purchased. While an item may be on the ESL, it is an indication of intent to purchase, rather than a guarantee that the item will be purchased. Purchase history (like present techniques) can be compared with intentional list items providing a way to gauge the likelihood of purchase, thereby improving the list based forecast for inventory and promotions. The disclosed subject matter improves upon strict historical/statistical inventory and promotion techniques through access to ESLs, which are indicative of a specific intent to purchase the listed items. When these anticipatory ESLs are combined with actual purchase data, an intention gauge (actual purchase divided by intended purchase) is created that may further refine the forward looking requirements, e.g., by placing greater weight on anticipatory ESLs from users with a high intention gauge. 
     The result is that the disclosed subject matter may benefit retailers by providing them an accurate picture of consumer demand based upon specific intention. Consequently, the retailers can more reasonably plan inventory, thereby reducing capital tied up in excess inventory and provide sufficient stock-on-hand to meet consumer demand. Additionally, the retailers may better plan promotions to customers that have a specific intention to purchase items related to the promotions. The customers benefit by having access to products based on their intention-list (with items being available when and where they want/need them) and the retailers and customers both benefit by retailer promotions that are targeted to the appropriate consumer at reduced costs. 
     Subject matter describing retail promotion and inventory management based on anticipated customer or end user behavior is also disclosed. The anticipated behavior is derived from ESLs provided by the end user from a web screen and/or mobile phone. The ESL may be voluntarily provided by the end user in exchange for consumer preference promotions based on the listed related items. The inventory management is derived from the provided list as a projection of future inventory requirements for the store. 
     Disclosed embodiments also encompass systems and methods for incorporating service requests for devices in the home and office into an ESL. A system may include a mobile device configured with a shopping assistant and an ESL. The mobile device may have local wireless capability, e.g., Bluetooth and/or WiFi capability, and would use the same to establish a service support relationship with devices or assets that require periodic maintenance or supplies. Such devices or assets may include computers, printers, water filters, air conditioning filters, automobiles, and the like. Depending on its communication capabilities, an asset may notify the mobile device shopping assistant when the asset needed service; for example, a printer may need a new color cartridge. The shopping assistant would then convert these notifications into service requests and include the service requests in the mobile device&#39;s ESL. 
     In cases where an asset lacks communication facilities (a “dumb” asset), yet still requires periodic servicing, a dumb asset proxy may generate periodic service notices that the shopping assistant can respond to. The dumb asset proxy may have access to a list of commonly encountered dumb assets, for example, air conditioning filters. Users may select which dumb assets they wish to receive periodic service notices for and the proxy would generate the requested requests for the applicable dumb assets at selected intervals. The dumb asset proxy may reside on the mobile device or elsewhere. Alternatively, a signaling device or other type of communication facility could be attached to a dumb asset. The signaling device may include a sensor that enables the signaling device to monitor a parameter of the asset, e.g., air flow through an air conditioning filter, and signal the shopping application when the monitored parameter fails to comply with a specified criteria. 
     Some assets may have communication facilities and interfaces, but those communication facilities and interfaces may not comply with communication protocols supported by the mobile device. For example, motor vehicles may have onboard diagnostic (OBD) facilities and an OBD-II interface that provide a wealth of diagnostic information in a standardized format, but not in a format that the mobile device would generally support. In cases such as these, a proxy in the form of a Bluetooth adapter could be added to the asset&#39;s communication interface, e.g., the OBD-II interface on a motor vehicle to provide notice when both routine service intervals and other extraordinary events occur. 
     Consumers and end users have to maintain and service all manner of modern devices/assets. The disclosed service for automating service requests for assets and integrating the service requests into the ESL encompasses periodic replacement of consumables that can be performed by the end user or a service representative for the applicable device or asset. To extend the life and service of this equipment, these consumables must be replaced. Keeping track of all of this may be an ongoing inconvenience for an end user. 
     The disclosed subject matter informs, by periodic electronic notices or interrogation and push notices, the mobile device of the user of the need for service for various personal/business devices or assets. A shopping assistant residing on the mobile device may schedule applicable service or include applicable replacement parts on an ESL. The mobile device may query the applicable asset or a proxy connected to the asset to determine whether service is required or to verify that the connection with the applicable asset is working normally. The ESL may be shared with applicable retailers who may in turn provide the end user with an incentive to visit the retailer to purchase one or more of the items listed on the ESL. 
     Disclosed subject matter still further relates to providing incentives for social network members to opt into a promotional program associated with a retailer or other seller of goods or services. The disclosed subject matter provides for the tracking of social network members who participate in the promotional program. The retailer may be or include a brick and mortar store and an incentive to visit the brick and mortar store may be provided. Such incentives may include offering enhanced differential coupon value for a store visit over an online, web-based purchase. 
     In one embodiment, retailers tender store and product coupons to participant customers or end users that voluntarily opt in (subscribe) to receive the coupons. The end users may then refer their social network contacts to the incentive program by encouraging them to submit their web and phone addresses (email, instant messaging (IM), short messaging system (SMS), or the like) to the retailers. This process may continue as long as the coupon tender is active. The coupon tender period may be limited so as to create scarcity and consequent value. The limit could be time, product quantity, number of participants or any other factor or changing factor determined to generate interest. 
     The social network referrals would be captured by the disclosed subject matter and used to identify primary lead generators, as well as market preference data for future demand generation. In one embodiment, interest would be promoted by increasing coupon value for lead-referral. The more participants, the more discount for the leaders and/or participants. Alternatively, additional coupon promotions and advertising may be offered during the tender period. Demand shaping for web and brick and mortar stores would be managed by differential coupon value for one or the other depending on where the coupon is exercised. For example, if there was a desire to drive demand to the brick and mortar store, then the coupon would have greater value at the store. The system also supports ‘herd purchase’ where an end user may gather a group (the herd) together and solicit a discount coupon from a participating retailer based on the size of the herd. The retailer may offer this facility to participants at any time on a range of goods; overstock or end of season. 
     In the following description, details are set forth by way of example to facilitate discussion of the disclosed subject matter. It should be apparent to a person of ordinary skill in the field, however, that the disclosed embodiments are exemplary and not exhaustive of all possible embodiments. Throughout this disclosure, a hyphenated form of a reference numeral refers to a specific instance of an element and the un-hyphenated form of the reference numeral refers to the element generically or collectively. Thus, for example, widget  12 - 1  refers to an instance of a widget class, which may be referred to collectively as widgets  12  and any one of which may be referred to generically as a widget  12 . 
       FIG. 1  depicts a mobile device  110  and other selected elements of an embodiment of a system  100  suitable for providing assistance to a shopper or other type of mobile device user  125  within a store  102 . The embodied system  100  includes a store server  104  suitable for detecting either an interaction between mobile device  110  and a store item  120  or another type of event associated with mobile device  110  and store item  120 . Store server  104  may respond to detect the interaction or other type of event, by accessing a store planogram or other type of database  108 , which may be remotely located or resident on server  104 . The depicted database  108  includes a data structure, identified as planogram  109 , indicative of a position of store item  120  within store  102 . Store server  104  may retrieve position data applicable to store item  120  from planogram  109  and estimate a position of user  125  within store  102  based on the retrieved data. Store server  104  may then use the estimate of the user&#39;s position to provide user  125  with information that is based, at least in part, on the estimated position. In various embodiments, the event associated with mobile device  110  and shopping item  120  may be communicated to store server  104  by a message from mobile device  110 . 
     Referring to  FIG. 2 , selected elements of an embodiment of mobile device  110  having subvocal recognition (SVR) functionality are depicted. SVR refers to a process of detecting subvocalization and converting it to a digital text-based output. SVR refers specifically to the detection of subvocalization that is inaudible. Subvocalization refers primarily to the movement of muscles associated with speaking. Most subvocalization is undetectable without the aid of machines. Subvocalization involves movements of the tongue and vocal cords that can be interpreted by electromagnetic sensors. NASA and others have been developing SVR systems that can interpret words using nervous signals gathered from sensors placed on the throat&#39;s exterior since 1999. 
     In an SVR implementation, a set of one or more subvocal sensors is attached, in contact with, or otherwise located in close proximity to the vocals cords of the user, e.g., in contact with the user&#39;s throat. The subvocal sensors are configured to detecting movement of the vocal cords that do not produce audible sound. The subvocal sensors digitize data that is representative of the detected movement and provided to a subvocal application for processing to convert the movement to a recognizable output. 
     SVR may rely on electromyograms, which may be different for different speakers. SVR may employ statistical models that are dynamically adjusted to improve pattern-matching the more times a subject “speaks” through the electrodes. Relevant applications for this technology include applications where audible speech is impossible, including, e.g., for astronauts, underwater Navy Seals, fighter pilots and emergency workers charging into loud, harsh environments. 
     In the depicted embodiment, mobile device  110  includes a processor  201  having access to tangible computer readable storage media, collectively represented in  FIG. 2  as storage  210 . Storage  210  may contain or include one or more software applications including an application identified as shopping assistant  212 . Storage  210  may further include one or more data structures including a data structure identified as ESL  214 . Mobile device  110  as shown in  FIG. 2  further includes peripheral elements that are accessible to processor  201  including a scanner  250 , a display  204 , and keypad control elements  202 , which may implemented as hardware buttons, soft keys, or the like. Mobile device  110  as shown further includes a microphone  206 , a radio frequency (RF) module  230  suitable for establishing cellular communication, a camera  240 , a speaker  208 , and a local wireless adapter  220  suitable for supporting communication with a wireless data network, e.g., a Bluetooth or WiFi network, that may be confined within store  102  and locations in close proximity to store  102 . Mobile device  110  as depicted in  FIG. 2  may be characterized by its ability to support cellular communication including voice communication and text message communication as well as wireless data communication including Web communication, email communication, instant messaging communication, and the like. Mobile device  110  may include selected elements of commercially distributed smart phones including, as an example, an iPhone® brand phone from Apple, configured with the aforementioned devices. 
     Mobile device  110  may be utilized to participate in one or more of the following events: (i) scanning a code of a store item using scanner  250 , (ii) taking a picture or otherwise capturing an image of a store item using camera  240 , (iii) detecting an RF identification (RFID) of a store item using RF module  230 , or (iv) performing a user initiated modification of an ESL stored in storage  210  of mobile device  110  and maintained by shopping assistant  212 . The event may then be transmitted by mobile device  110  using wireless adapter  220  to server  104 . Information (including store location, promotional materials, store maps, directions, or requesting additional information from the user in order to assist with determining the user&#39;s location) may be provided to user  125  via display  204  or speaker  208  of mobile device  110 . 
     Mobile device  110  as depicted in  FIG. 2  further includes a peripheral adapter  260 . Peripheral adapter  260  is configured to communicate with a subvocal sensor  270 . Subvocal sensor  270 , when in use, may be in contact with or in close proximity to the throat or vocal cords of a speaker (not depicted) in  FIG. 2 . In some implementations, peripheral adapter  260  employs a standardized protocol to communicate with subvocal sensor  270 . Peripheral adapter  260  might, for example, comprise a universal serial bus (USB) compliant adapter, a firewire (IEEE 1394) compliant adapter, or any of various other adapters. Although subvocal sensor  270  is depicted as being coupled to peripheral adapter  260  via a wireline connection, other embodiments may employ a wireless communication protocol, such as a Bluetooth or other type of personal area network protocol, to effect communication between subvocal sensor  270  and peripheral adapter  260 . In these embodiments, local wireless adapter  220  and peripheral adapter  260  may achieve the same or similar functionality. 
     In some embodiments, subvocal sensor  270  is implemented as a tuned electromagnetic resonator collar (TERC). Using magnetic resonance imaging (MRI) sensing techniques, a TERC detects changes in capacitance caused by movement of the vocal cords. In other embodiments, subvocal sensor  270  may include electromyographic sensors, positioned on the neck, to detect changes in impedance that occur during speech. Regardless of the specifics of the subvocal detection technique or techniques employed, mobile device  110  may incorporate software for providing a neural network that processes data and identifies patterns of words. In the depicted embodiment, for example, the subvocalization processing may be embedded within a subvocal module  216  of shopping assistant  212 . 
     Disclosed embodiments may be implemented as methods of use and/or computer software, both of which may be represented as flow diagrams where, in the case of computer software, the flow diagram blocks correspond to instructions embedded in a computer readable medium such as storage  210  of mobile device  110  or storage associated with store server  104 . As depicted in  FIG. 3 , a disclosed method  300  includes detecting (block  302 ) mobile device  110  upon entering store  102  and registering mobile device  110 , anonymously or non-anonymously (block  303 ). Server  104  may extract or otherwise access (block  304 ) an ESL from mobile device  110  and provide promotional materials, e.g., coupons, or other assistance to user  125  by way of mobile device  110 . When an interaction or another type of event associated with mobile device  110  and store item  120  occurs (block  306 ), the event may be detected (block  308 ) by server  104 . Server  104  accesses or otherwise consults (block  310 ) planogram  109  to approximate the location of user  125  based on the information provided as a result of the detected event. Server  104  may then provide (block  312 ) data or other information to user  125  via mobile device  110  based on the estimated location of user  125 . In some instances, store item  120  may be a stock item of the store available for sale or use by consumer/users and in other instances store item  120  may be a wireless transceiver affixed to a known position within store  102 . 
     Referring now to  FIG. 4  and  FIG. 5 , selected elements of embodiments of a system  400  and method  500  of leveraging ESLs to manage inventory are disclosed. In an embodiment depicted in  FIG. 5 , method  500  includes enabling (block  510 ) an end user to provide an ESL  214  to a network resource  420 . In some embodiments, the items contained in ESL  214  represent items that may be purchased in the future by the end user. The end user may maintain an ESL  214 - 1  on mobile device  110  and may separately, or in addition to, maintain an ESL  214 - 2  on computer  410 , which may represent a home computer of the end user. If maintained on both mobile device  110  and computer  410 , ESLs  214 - 1  and  214 - 2  may be automatically synchronized so that any revisions made to ESL  214 - 1  will be automatically reflected in ESL  214 - 2  and vice versa. Alternatively, the end user may download an application from network resource  420  or from another available resource which application is suitable for creating ESL  214 . The end user may provide ESL  214  to network resource  420  via network  415  by mobile device  110  and/or computer  410 . In addition, ESL  214  may be generated via an online interface to network resource  420 . 
     In the depicted embodiment, the end user may be incentivized (or induced or motivated) (block  515 ) to provide ESL  214  to network resource  420 . Such incentivizing may include notifying the end user of sale events concerning items on the ESL or providing a coupon to the end user. In some embodiments, the coupon may be for at least one item on ESL  214 . In another embodiment, a store  102  or other retailer may be associated with network resource  420  and in such embodiment, network resource  420  may be implemented as a Web server portal of store  102  or such other retailer. Responsive to the end user providing ESL  214  to network resource  420  as determined in block  520 , ESL  214  is used by inventory management application  425  to predict and adjust (block  525 ) future inventory needs. 
     Inventory management application  425  may be utilized to maintain information tracking items on ESL  214  versus items purchased by the end user so that when ESL  214  is used to predict future inventory needs, such predictions include predicting future levels of inventory based, at least in part, on the tracking information. In some embodiments, the tracking information may be obtained during predetermined intervals. In yet additional embodiments, the tracking information may be utilized to determine a likelihood of purchase factor for the end user. In the depicted subject matter, responsive to an item listed on the ESL not being in stock at the store, information indicative of another store location where the item is in stock may be transmitted (block  530 ) to the end user.

     In accordance with some embodiments, system  600  and method  700  provide assistance to an end user or shopper  125  to locate items within store  102 . Accordingly, instructions  1424  include instructions for detecting a wireless device in proximity to a store, identifying items in an ESL resident in the wireless device, and accessing item location data to provide guided shopping information to the wireless device, wherein the guided shopping information facilitates navigation of the store to locate the ESL items. 
     Referring now to  FIG. 15 , selected elements of an embodiment of a method  1500  for providing shopping assistance via subvocal interaction between a user and the mobile device are depicted. In the depicted embodiment, method  1500  includes enabling (block  1502 ) a mobile device to detect an SVM from the user. The SVM is associated with or otherwise corresponds to an item in the store. 
     Method  1500  further includes enabling (block  1503 ) the mobile device to transmit a request in response to detecting the SVM. The request includes information indicative of the store item. For example, the request may be a request for position information, i.e., a request for information that is indicative of a location or position of an item in the store. The request may also be or include a request for price information, indicative of a price of an item in the store, and/or a request for inventory information, indicative of an inventory of the item in the store. Inventory requests might include, as examples, requests to determine the in-stock sizes and or colors of a particular item of inventory in the case of clothing. 
     Enabling the mobile device to detect the SVM may include enabling the mobile device to detect the message via a subvocal sensor coupled to the user. The subvocal sensor may be in contact with the user, for example, in contact with the user&#39;s throat in proximity to the user&#39;s vocal cord(s). The subvocal sensor may coupled to the mobile device wirelessly using a personal area network such as Bluetooth or an analogous protocol. In other embodiments, the mobile device may be coupled to the mobile device via a wire, for example, a USB cable connected to a USB port of the mobile device. 
     The mobile device may be configured or enabled to distinguish between a vocal message and an SVM. For example, the mobile device may include an SVM module configured specifically to detect and process SVMs. In these embodiments, the SVM module of the mobile device may be enabled to ignore vocal messages, enabling the user to carry on two tasks independently, namely, a subvocal interaction with the store via the mobile device and an audible conversation with one or more persons in proximity to the user. 
     The SVM may include information indicative of any of various attributes or characteristics of a store item. For example, an SVM may represent an alphanumeric sequence embedded in a scannable code of the store item. 
     Method  1500  as depicted further includes enabling (block  1504 ) the mobile device to receive a reply. The reply includes information responsive to the request. The reply information may include information retrieved from a store planogram as described above. The depicted embodiment of method  1500  further includes enabling (block  1506 ) the mobile device to provide the responsive information to the user. In addition to or as a part of the reply, some embodiments of the claimed method may include providing information promoting a related item, to the user.
