DETAILED DESCRIPTION

Some embodiments of this disclosure, illustrating all its features, will now be discussed in detail. The words “comprising,” “having,” “containing,” and “including,” and other forms thereof, are intended to be equivalent in meaning and be open ended in that an item or items following any one of these words is not meant to be an exhaustive listing of such item or items, or meant to be limited to only the listed item or items.

Preferred embodiments of the present disclosure will be described hereinbelow with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail to avoid obscuring the present disclosure in unnecessary detail.

Systems and methods are provided for enabling portable electronic devices to gather information about a selected object and present the information on a display device. Using any applicable visual detection device (e.g., a camera, scanner, or other device) on the portable electronic device, the user may select an object by scanning or capturing an image of symbology (e.g., barcodes) associated with the object. The object may be an article of commerce, product, service, or any item associated with various types of symbology.

Many types of detection systems are available to enable a user to select an object. One such system may be an image capture device containing a charge couple device (CCD) or camera, where the user may scan or take a picture of symbology (e.g., a barcode) placed on or associated with an object. Portable devices (e.g., IPhone from Apple, Android from HTC, etc.) may include decoding software to be used to decode the scanned barcode symbology. In a further embodiment, the object may contain Radio Frequency Identification (RFID) tags used to identify the object to a reader device. Furthermore, if the portable electronic device contains an image capture device (e.g., a camera) and character recognition software, the user may take a picture of the object and the character recognition software may be used to decode the image and/or name of the object.

When symbology has been detected according to the embodiments of the present disclosure, the portable electronic devices are configured to send the symbology information to the appropriate applications residing on the portable electronic device. These applications are instructed to decode the symbology, if not already decoded by other applications on the portable electronic device. The decode string representing the decoded symbology may be used to determine the object associated with the symbology and then gather information about that object. Furthermore, the decode string is sent to a server that is configured to decode symbology (if necessary), identify one or more objects associated with the symbology, retrieve information about the one or more objects, and send the information to the portable electronic device. The portable electronic device may then combine the information from the different sources and display the information to the user.

Some applications that may be downloaded to portable electronic devices include symbology scanning and/or decoding programs. Examples of applications that allow scanning include Neomedia's Neo Reader, Microsoft's Smart Tags, Android's Shop Savvy, Red Laser, ScanBuy, etc. However, when a user wishes to scan an object, the user must then select an application on the portable electronic device that is capable of accomplishing the desired functions. Since a user may have dozens of applications loaded on his or her portable electronic device, it may be difficult to select the appropriate application for executing the scanning functions. The present disclosure provides for the automatic selection of scanning application upon recognition of applicable symbology. The embodiments of the present disclosure also allows for the selection of the best application or applications for scanning a particular symbology when multiple scanning applications reside on the device. In some embodiments, the symbology managing application may be configured to recognize decodable symbology when the user is using the portable electronic device for a simple image capture process. In this sense, the device may allow the user to select whether or not the symbology is to be decoded.

Further, systems and methods are provided for discovering objects in an environment and successively gathering information related to the discovered objects. Using a suitable scanning technique, on the portable electronic device, the user may be able to detect an object. Successively, the user may select such object based on information corresponding to the object. The object may be an article of commerce, product, service, or any item associated with an RFID tag.

Many types of detection techniques are available to enable a user to select an object. One such technique may be Radio Frequency Identification (RFID). RFID tags may be used to identify the object by a portable electronic device. The portable electronic device upon detecting RFID tags associated with the object may identify an identity of the RFID tag. Such identity of the RFID tag may be sent to a server for extraction of information. The server may retrieve information corresponding to the identity of the RFID tag. Such information may be transmitted to the portable electronic device. Based on the received information related to the product, the user may select or discard the object for making a purchase.

The present disclosure provides for the automatic detection of an object in a store using the RFID scanning technique. Further, the detected objects may be filtered based on user inputs. Such filtering of the objects may either be performed on the portable electronic device or on a server.

According to various embodiments of the present disclosure, various portable devices already owned by many customers can be enhanced with software applications to enable information retrieval procedures as described in the present disclosure. The portable electronic device may use any suitable communications protocols including but not limited to WiFi (a, b, c d, n, x), cellular communications such as GSM, CDMA, FOMA, etc., infrared communications, cabled communications, Bluetooth communications, satellite communications, etc.

FIG. 1 is a diagram illustrating an embodiment of a communication system 10 in accordance with various implementations of the present disclosure. The communication system 10 in this embodiment includes a server 12, a storage medium 14, a portable electronic device 16, one or more satellites 18, one or more satellite dishes 20, one or more mobile terminal communications towers 22, one or more Wi-Fi towers 24, each of which may be configured to transmit and/or receive signals to the other elements of the communication system 10 via a communication network 26. For example, the portable electronic device 16 may be configured to communicate with the server 12 via the communication network 26 to transfer cellular voice signals, data signals, or other types of signals.

The portable electronic device 16 and server 12 may be connected to the communication network 26 (e.g., the Internet) by any suitable means, such as, for example, hardwired and/or wireless connections, such as dial-up, hardwired, cable, DSL, satellite, cellular, PCS, wireless transmission (e.g., 802.11a/b/g), etc. It is to be appreciated that the communication network 26 may be a local area network (LAN), wide area network (WAN), the Internet, or any other type of network that couples a plurality of computers to enable various modes of communication via network messages. Furthermore, the server 12 may communicate using various protocols, such as Transmission Control Protocol/Internet Protocol (TCP/IP), File Transfer Protocol (FTP), Hypertext Transfer Protocol (HTTP), etc. and secure protocols such as Internet Protocol Security Protocol (IPSec), Point-to-Point Tunneling Protocol (PPTP), Secure Sockets Layer (SSL) Protocol, etc. The server 12 may access the storage medium 14, which is configured to store a database containing information about a number of objects, such as information about the specifications, cost, features, and other details about the objects, and other information and data.

According to some embodiments, the objects of interest may refer to products and/or services sold at various stores. As will be appreciated from the description below, a unique identification code is associated with each product and/or service and may take many forms, such as a barcode number, a UPC number, an alphanumeric number assigned to the product, a name of the article (e.g., “Batman Begins DVD”), etc. The identification codes may be attached to or printed on the products or in some other way associated with the products. According to other embodiments, the products or items may refer to any type of object for which the user wishes to receive information, identifiable by a unique identification code.

The user may utilize the portable electronic device 16 to obtain a visual representation of an object 28 or portion of the object 28. For example, if the object 28 includes a barcode 30, the portable electronic device 16 may be configured to scan the barcode 30 and decode the barcode to acquire an identification code of the object. In some embodiments, the portable electronic device 16 may be configured to capture an image of the barcode 30 and decode the barcode to acquire the associated identification code of the object. Using standard and existing computer processing power and software solutions such as Attrasoft Image recognition software, or optical character recognition software (OCR software such as OmniPage or Readlris), the image or name of the object may be decoded to determine the identity of the object.

In another embodiment, the user may enter an identification code of the obj ect or the name of the object via a user interface, if the portable electronic device 16 contains a user interface allowing user keyboard input. In some implementations, the user may speak the name of the product into the portable electronic device 16 using a microphone and the audio signals may in turn be processed into digital form via speech recognition software.

In a further embodiment, some objects may contain Radio Frequency Identification (RFID) tags. The portable digital device 16 may contain an RFID reader 71 to detect presence of the product comprising an RFID tag and successively resolve the identity of the product. In another embodiment, the name or identification code of an object may be broadcasted via the Wi-Fi tower 24 over a predetermined range. Furthermore, the name or identification code of an object may be broadcast from another portable electronic device (e.g., a gaming device, mobile phone, etc.). Here, a user may approach the other portable electronic device having an application stored in memory or currently being used. The other portable electronic device may be configured to automatically broadcast the identification code of the object (i.e., application) or the user of the other portable electronic device may initiate a transfer of the identification code, e.g., via an infrared port or other wireless port, to the first user.

The portable electronic device 16 may use the resources with the device itself to obtain information about the identity of the object and other details of the object. Also, once the product is identified, the portable electronic device 16 may use communications protocols including but not limited to Wi-Fi (a, b, c d, n, x), mobile phone communications such as GSM, CDMA, FOMA, etc., infrared communications, cabled communications, Bluetooth communications, satellite communications, to transmit the identification code to the server 12 on the global computer network (GCN), e.g., the Internet. It is to be appreciated that the portable electronic device 16 may use any one or a combination of protocols to transmit the identification code to the server 12. For example, the portable electronic device 16 may employ a telecommunication protocol to transmit the identification code via the communication module 26. In another embodiment, the portable electronic device 16 may communicate to the server 12 via the same Wi-Fi tower 24 that broadcasts a list of objects for which information is available, e.g., a hot spot in a retail location.

The server 12 may be maintained by a vendor associated with the object. For example, in the case of seeking information about a Warner BrothersTM DVD movie, the server 12 may be a Warner Brothers server connected to a Warner Brothers website. However, the server 12 may also be a vendor not associated or even competing with the object. For example, if the product is a Warner BrothersTM DVD movie, the server 12 may be an e-commerce site such as Amazon.com that offers DVD movies from many companies including Warner Brothers.

When this is received, the object identifying module 96 is configured to identify the object or objects that are associated with the symbology or decode string. The object identifying module 96 may be configured to utilize the database management module 94 to lookup information in a database (e.g., storage medium 14) that contains the relationships between objects (e.g., products) and corresponding symbology or character strings that may be obtained by decoding the symbology.

After the object of interest is identified by the object identifying module 96, the information retrieving module 98 is configured to retrieve information about the specific object or objects. The information retrieving module 98 may also utilize the database management module 94 to retrieve information from one or more databases. The information retrieving module 98 may access various resources available via the communication network 26 to obtain the needed information pertaining to the object or objects.

FIG. 5 is a block diagram of an embodiment of a portion of the storage module 66 shown in FIG. 3. For example, several applications may be stored in the storage module 66, including, among others, the symbology management module 80 shown in FIG. 3, an image capture application 110, a scanning application 112, and other visual detection applications 114. According to some embodiments, the other visual detection applications 114 may include detection applications that detect in a way other than visually.

The image capture application 110 may be configured to operate with an image capture device (e.g., camera). In some embodiments, the image capture application 110 may run in the background while other applications are running on the portable electronic device 16. While running in the background, the image capture application 110 may be configured to automatically search for recognizable symbology. For example, the image capture application 110 may be configured to search for bar codes. The symbology management module 80 may control these operations such that when symbology is detected automatically, the symbology management module 80 may prompt the user to determine if he or she wishes that the portable electronic device 16 proceeds with the decoding of the symbology and retrieving information about an object associated with the symbology.

According to various implementations, the image capture application 110 may be configured to respond to a user's prompt or trigger to capture a single image. The symbology management module 80 may be configured in the case of this typical image capture process to automatically search for and decode any symbology that may exist in the captured image. Again, the symbology management module 80 may prompt the user as to whether he or she wishes to pursue the decoding of the symbology, if it exists, and retrieving information about an object associated with the symbology.

The scanning application 112 may operate in a way that is similar to that of the image capture application 110 except that the scanning application 112 responds to images obtained by a scanning procedure instead of an image capture procedure. The symbology management module 80 may continue analyzing scanned data to determine if symbology is detected, either during a user-initiated trigger or when detected automatically while the scanning application 112 is running in the background. The symbology management module 80 may also operate in a similar way with respect to the other visual detection applications 114 based at least on the particular formats, protocols, functions, etc. of the other types of detection devices, which may be incorporated in the portable electronic device 16 and which may be capable of sensing any type of symbology.

FIG. 6 is a flow diagram showing an embodiment of a method that may be performed by a server, such as the server 12 described with respect to FIGS. 1 and 4. The method includes receiving a decode string from a portable electronic device (e.g., device 16), as indicated in block 120. In some embodiments, the method may include receiving encoded symbology information and then decoding this information to obtain the decode string. As indicated in block 122, the method includes identifying the object or objects associated with the decode string. For example, the object may be an article or commerce. From the identity of the object(s), the method includes retrieving information about the object(s), as indicated in block 124. For example, information about various objects may be obtained from any database or resource available. When the information has been retrieved, the information is sent to the portable electronic device (block 126).

FIGS. 7A, 7B, and 7C collectively form a flow diagram showing an embodiment of a method that may be performed by a portable electronic device, such as the portable electronic device 16 described with respect to FIGS. 1-3 and 5. In this embodiment, the method includes allowing a user to select preferences as indicated in block 130. Default presets may initially be provided, but the user may choose to select other preferences at any time as needed. As indicated in block 132, one or more visual detection systems are run in the background of the device, where other programs or systems are given priority with respect to processing steps over the one or more visual detection systems, unless of course one of the visual detection systems is currently being used. The background systems may include image capture systems (e.g., camera systems), scanning systems, or other detection systems capable of detecting symbology.

In decision block 134, the method includes determining whether a trigger from a visual detection system is initiated by the user. For example, if a detection system is already running, the user may initiate an image capture, scan, or other input operation (e.g., by pressing a button to take a picture with a camera on the portable electronic device). If the system does not receive a trigger, the method proceeds to decision block 136, which determines whether or not decodable symbology is automatically detected. In some embodiments, the automatic detection of decodable symbology may involve detection by any visual detection system running in the background. If no user-initiated trigger is detected in block 134 and no decodable symbology is detected in block 136, the method loops back to decision block 134 until an applicable image is detected.

If a background application detects decodable symbology according to decision block 136, the method proceeds to block 138. In block 138, the user is alerted that an automatically detected image contains some type of symbology. As indicated in decision block 140, it is determined whether or not the user wishes that the symbology is decoded. If not, the method skips the remaining steps and comes to an end. If symbology is to be decoded, the method goes to decision block 142, which indicates that it is determined whether or not a visual detection application has been pre-selected. If so, the method proceeds to block 144 (FIG. 7B). Otherwise, the method goes to block 160 (FIG. 7C).

As indicated by block 144, shown in FIG. 7B, the detected symbology is sent to one or more pre-selected visual detection applications for decoding and information retrieval. The pre-selected visual detection applications may have been selected based on the selected preferences made with respect to block 130. The visual detection applications and/or related decoding software may be configured to decode the detected symbology to obtain a decode string. Also, the applications may be configured to obtain information about one or more objects associated with the decode string decoded from the detected symbology. As indicated in block 146, the method includes receiving and storing information from the visual detection application(s).

According to block 148, the decode string is also sent to a remote server (e.g., server 12). Later, the method receives information from the remote server as indicated in block 150. The information from the server may be related to information about one or more objects identifiable by the decode string. As indicated in block 152, the information from the visual detection application(s) is combined with information from the remote server according to various implementations. At this point, the method includes displaying the information on a display screen of the portable electronic device.

While or after the information is displayed, the method also includes enabling the user to store the information if desired, as defined in block 156. In addition, the user is given an option to run a purchasing application to enable the purchase of the object or objects if desired. This may also be performed while or after the information is displayed. Therefore, one advantage of displaying information for the user is to provide appropriate data to inform the user of objects (e.g., products) that the user may consider purchasing. With the information, the user may be able to make a more informed purchasing decision. After the information is displayed and stored (if desired) and one or more objects are purchased (if desired), the method comes to an end.

When visual detection applications have not been pre-selected by the user, as determined in decision block 142, the method jumps ahead to block 160 as shown in FIG. 7C. In block 160, the symbology is decoded to determine a category of the object. As indicated in block 162, the method includes determining the appropriate visual detection application(s) based on the object's category. According to decision block 164, it is determined whether or not multiple applications were deemed to be appropriate. If not, the method goes to block 166, which indicates that the decode string is sent to the one appropriate application for retrieving the information. If it is determined in decision block 164 that multiple applications are appropriate, the method goes to block 168. As indicated in block 168, the user is enabled to select one or more of the applications.

In block 170, the decode string is sent to the selected application(s) for information retrieval. After the decode strings are sent off for information retrieval according to blocks 166 and 170, the method returns to block 146, which involves receiving and storing the information from the visual detection application(s) and the following processes as discussed above.

In an alternate embodiment, the portable electronic device 16 may comprise a Radio Frequency Identification (RFID) reader 71. The RFID reader 71 may detect objects present nearby the user, in an environment. The RFID reader 71 may detect RFID tags attached to the objects, in order to detect the objects. Upon detection the RFID tags, a computer processing module 70, of the portable electronic device 16, may identify an identity of the RFID tag. In one case, the identity of the RFID tag may be an alphanumeric string. For example, the identity may be ABWP8926. Such alphanumeric string may be unique for each RFID tag attached with different objects.

Successively, the identity of the RFID tag may be sent to the server 12, by an antenna 57 of the portable electronic device 16. A computer processing module 84 of the server 12 may identify information corresponding to the identity of the RFID tag. The computer processing module 84 may retrieve such information related to the RFID tag, from the data 14, based on the identity of the RFID tag. The information corresponding to the identity of the RFID tag may include but not limited to a price of the object, description of the object, location of the object in a store, manufacturer of the object, warranty of the object, care instructions for the object, size of the object, and warning about the object. The information corresponding to the identity of the RFID tag may further comprise recommendations to similar objects related to the object.

Successively, the antenna 57 of the portable electronic device 16 may receive the information corresponding to the identity of RFID tag. Here, the information corresponding to the RFID tag denotes the information about the object. Such information may be displayed on the display device 42 of the portable electronic device 16, by the display module 62. In one case, the information may be overlaid on a digital image of the object while presenting the information to the user. Using such information, the user may get to know about availability of the object without even looking for the object and the user may buy such object using the portable electronic device 16.

In one embodiment, the user may provide a user input to the portable electronic device 16 for searching objects. The user may provide the user input to the input module 64 by operating the buttons 50, of the portable electronic device 16. Post receiving the user input, the portable electronic device 16 may detect RFID tags attached with the objects by using the RFID reader 71. Successively, the computer processing module 70 may identify identities of the detected RFID tags. The portable electronic device 16 may send the identities of RFID tags and the user input to the server 12, using the antenna 57.

In one case, upon receiving the identities of RFID tags and the user input, the server 12 may filter the identities of RFID tags based on the user input. The server 12 may filter the identities of the RFID tags using the computer processing module 84. In another case, the server 12 may filter the identities of RFID tags based on previous user preferences, previous purchases made by the user, user's personal information, and a financial status of the user. Successively, the server 12 may identify information corresponding to the filtered identities of RFID tags. The server 12 may retrieve such information from the data 14, based on the filtered identities of RFID tags. As mentioned above, the information corresponding to the filtered identities of RFID tags may comprises details such as prices of the objects, description of the objects, locations of the objects in a store, manufacturers of the objects, warranties of the objects, care instructions for the objects, sizes of the objects, and warnings about the objects. The information corresponding to the filtered identities of RFID tags may further comprise recommendations to similar objects related to the obj ects.

Post filtering the identities of RFID tags, the portable electronic device 16 may receive the information corresponding to the filtered identities of RFID tags, using the antenna 57. Here, the information corresponding to the filtered identities of RFID tags denotes the information about the objects selected by the user, by providing the user input. Such information may be displayed on the display device 42 of the portable electronic device 16, by the display module 62. In one case, the information may be overlaid on a digital image of the object while presenting the information to the user. Using such information, the user may get to know about availability of selected objects where the objects are selected by providing the user input.

In an exemplary embodiment, the user may scan for objects present in his vicinity. The RFID reader 71 present in the portable electronic device 16, operated by the user, may detect numerous RFID tags associated with objects present nearby the user. The user may restrict such search of objects by providing a user input. For example, the user may wish to find Calvin Klein jeans and may provide the user query “Calvin Klein Jeans” to the portable electronic device 16. The identities of the RFID tags detected and the user query may be sent to the server 12.

The server 12 may filter the RFID tags based on the user query “Calvin Klein Jeans” i.e. RFID tags related to the Calvin Klein Jeans may be filtered and may be shown to the user. Successively, the user may be asked to further narrow down his choice of object. In one case, the user may be asked to provide inputs towards certain questions related to a gender, price, color, fabric type, and size related to the Clavin Klein Jeans. Based on the inputs provided by the user, the server 12 may filter the RFID tags and may identify the RFID tag attached with a relevant object desired by the user. The information related to the RFID tag attached with the object may be shown to the user by the portable electronic device 16. In this manner, a user may find a specific object using the portable electronic device 16.
