Information in the form of content from websites is typically provided to many different types of devices and users. One type of device and user that is increasingly receiving more and more web content is a mobile device and a mobile user. A mobile device can be a portable computing device, a tablet computer, a smart phone, or any other portable, or mobile device that is capable of browsing and receiving web content.
One of the ongoing challenges when providing content to a user, and more particularly, to a mobile user, concerns the user's context, and how to provide content to the user based on the user's context. Examples of user context include, but are not limited to, location, whether the user is mobile or stationary, whether the user is driving, walking, shopping, traveling, indoors, outdoors, etc.
Therefore, it would be desirable to have a way of determining a user's context and then providing content to the user based on the context.
An embodiment of a method for providing contextual content to a device includes determining context of a device, applying metadata to a request for a website, the metadata corresponding to the context of the device, sending the metadata to the website, and receiving from the website content based on the context.
In the figures, like reference numerals refer to like parts throughout the various views unless otherwise indicated. For reference numerals with letter character designations such as “102a” or “102b”, the letter character designations may differentiate two like parts or elements present in the same figure. Letter character designations for reference numerals may be omitted when it is intended that a reference numeral encompass all parts having the same reference numeral in all figures.

The context server 115 can comprise a server computing device that can be located internal to or external to the network 106. In an embodiment, the context server 115 is located external to the network 106 and is connected to the network 106 over a bi-directional communication channel 117 so that it can operatively communicate with any of the elements connected to the network 106. The context server 115 is also depicted in dotted line inside of the network 106 to indicate that the functionality described with respect to the context server 115 may occur within the network 106. The context server 115 can comprise one or more hardware elements and software modules that can enable the context server 115 to route for contextual redirections, and manage the flow of context aware metadata, in that it applies, appends, attaches, or otherwise associates metadata to an HTTP or HTTPS request received from the user device 102, where the metadata identifies the context of the user device 102 and provides context aware metadata to the proxy server 108 and web server 110. The context aware metadata can be appended to an HTTP or HTTPS request sent by the user device 102, the metadata defining, corresponding to, or otherwise identifying the context of the user device 102. The context of the user device may be, for example, whether the user device is moving or stationary, the specific location of the user device, whether the user of the user device is walking, shopping, driving, indoors, out of doors, etc. An example of providing context aware content is a website tailoring content provided to a user based on whether, for example, the user is at a retail location or shopping on-line.
In an embodiment, the context server 115 may comprise a context awareness metadata software module 122, which generally manages the flow of context aware metadata. The context server 115 also may comprise a network-based monitoring software module 125, which can comprise one or more software modules or elements that allow the context server 115 to monitor and communicate with any element connected to the network 106 to monitor, extract, or otherwise obtain contextual information about a user device 102 connected to the network 106 without the user device 102 sending the contextual information.
The apparatus 100 also comprises an Internet content adaptation protocol (ICAP) element 112, a position mapper 114 and a location engine 116. The ICAP element 112 runs an HTTP-like protocol which is used to extend a transparent proxy server, such as the proxy server 108, thereby freeing resources and standardizing the way in which functionality can be implemented.
The location engine 116 provides the current location of the user device 102. The location engine 116 can use any of triangulation, latency or access point data to detect the current location of the user device 102 typically by using information exchanged between the user device 102 and the access point 105 or other access points while the user device 102 is scanning for available WiFi access points. Typically, a WiFi network identifies a user device 102 using a media access control (MAC) address, which is a unique address assigned to each user device 102. When a user device 102 desires to communicate with a web server 110, the user device will send a dynamic host configuration protocol (DHCP) request to the network 106. A DHCP server (not shown) connected with the network 106 will issue the user device 102 an internet Protocol (IP) address. The IP address allows the user device 102 to communicate with the web server 110 via the network 106 and proxy server 108 using HTTP or HTTPS.
Depending on the implementation, the context awareness metadata software 122 manages one or more of the proxy server 108, ICAP element 112, position mapper 114, and the location engine 116 to identify the context of the user device 102 and provide, append, or otherwise associate context aware metadata with a request from the user device 102.
The ICAP element 112 receives a request for a modified header from the proxy server 108, the request for a modified to include contextual awareness metadata. The ICAP element 112 then requests the location of the user device 102 from the position mapper 114.
The location engine 116 provides the current location of the user device 102 to the position mapper 114. The location engine 116 can use one or more of triangulation, latency data or access point connection data to detect the current location of the user device 102.
The position mapper 114 receives IP and MAC address information related to the user device 102 from the network 106, and also receives location information related to the user device 102 from the location engine 116. The position mapper 114 uses the IP and MAC address of the user device 102 and the location of the user device 102 to return the location of the user device 102 to the ICAP element 112.
In particular, the position mapper 114 takes the IP address of the user device 102, and requests location information from the location engine 116 based on the MAC address of the user device 102. The position mapper 114 then returns location information to the ICAP element 112, which requested contextual information for the user device 102. In this manner, location information related to the user device 102 is sent back to the ICAP element 112, and the ICAP element 112 provides a modified HTTP header to the proxy server 108 with the location information of the user device 102. The obtaining of the contextual information related to the user device 102 is depicted using the logical connection 154. The proxy server 108 receives the modified header and provides a modified HTTP request to the web server 110, the modified request having the current location of the user device 102, thus allowing the web server 110 to provide contextual content to the user device 102 based on the device location.
The apparatus 100 also comprises a number of physical connections and logical connections. The term “physical” connection is meant to include any wired or wireless connection. The term “logical” connection is meant to include a connection that may occur between or among two or more devices without a direct physical connection. The physical connections are shown in solid line while the logical connections are shown in dotted line. Regardless of whether the connections are logical or physical, the connections can be wireless, wired, or any other connection known to those having ordinary skill in the art.
The user device 102 is connected to the network 106 over a wireless connection 132, which is also depicted as a logical connection 151. If externally implemented, the context server 115 is connected to the network 106 over a physical connection 117. The proxy server 108 is connected to the network 106 over a physical connection 134. The proxy server 108 is connected to the web server 110 over physical connections 136 and 138. The connections 136 and 138 may also traverse the network 106. The proxy server 108 is also connected to the ICAP element 112 over physical connection 142. The ICAP element 112 is connected to the position mapper 114 over physical connection 144. The position mapper 114 is connected to the location engine 116 over physical connection 146. The physical connections 117, 132, 134, 136, 138, 142, 144 and 146 can be any wired or wireless connections as known to those having ordinary skill in the art.
The web server 110 comprises a content adaptation software element 124 and a content presentation software element 129, a lookup table 125, and a software plug-in 127. The apparatus 100 also comprises a database 118 that is logically connected to the context server 115 over logical connection 152. The database 118 includes content aware metadata from sources other than the user device 102.
In the embodiment shown in
The apparatus 200 comprises a user device 202, a network 206, a context server 215, a proxy server 208, and a web server 210. The user device 202 comprises a browser 204, such as a hypertext transfer protocol (HTTP) web browser 204 for accessing and viewing web content.
In the embodiment shown in
Further, as depicted in dotted line within the user device 202, any background process 211 that can provide contextual metadata can be associated with the user device 202 to provide contextual metadata without the interaction of the web browser 204. The user device 202 also comprises an optional software module 229, which can be a plug-in, or other code that provides the ability to display contextual based content on the user device 202 through the web browser 204.
The user device 202 can be a stationary device or a mobile device. In an embodiment, the user device 202 is a mobile device, such as a smart phone, a tablet computing device, or any other computing device that can connect to the Internet.
In an embodiment, the network 206 comprises a number of functions, including, but not limited to, a wireless access point (AP), a router, a switch, a domain name server (DNS), a dynamic host configuration protocol (DHCP) server and other functions, all embodied by functional block 207. A wireless access point 205 is shown for illustration as the access point to which the user device 202 is wirelessly connected. The network 206 may comprise additional access points and may comprise a network of access points and related infrastructure forming a wireless network. The network 206 can comprise one or more of a local area network (LAN), a wide area network (WAN), and can also comprise at least portions the world wide web.
In the embodiment shown in
In an embodiment, the context server 215 may comprise a context awareness metadata software module 222, which provides, routes, or otherwise manages the flow of context aware metadata, in that it applies, appends, attaches, or otherwise associates metadata to an HTTP or HTTPS request received from the user device 202. The metadata identifies the context of the user device 202 and provides context aware metadata to the proxy server 208. The context server 215 also may comprise a network-based monitoring software module 225, which can comprise one or more software modules or elements that allow the context server 215 to monitor and communicate with any element connected to the network 206 to monitor, extract, or otherwise obtain contextual information from a user device 202 connected to the network 206, or to process contextual information provided by the native application 209 and/or the background process 211, on the user device 202.
The context aware metadata is appended to an HTTP or HTTPS request sent by the user device 202, the metadata defining, corresponding to, or otherwise identifying the context of the user device 202.
The apparatus 200 also comprises an Internet content adaptation protocol (ICAP) element 212, a position mapper 214 and a location engine 216. The ICAP element 212 runs an HTTP-like protocol which is used to extend a transparent proxy server, such as the proxy server 208, thereby freeing resources and standardizing the way in which functionality can be implemented.
The location engine 216 provides the current location of the user device 202. The location engine 216 can use any of triangulation, latency or access point data to detect the current location of the user device 202 typically by using information exchanged between the user device 202 and the access point 205 or other access points while the user device 202 is scanning for available WiFI access points. Typically, a WiFi network identifies a user device 202 using a media access control (MAC) address, which is a unique address assigned to each user device 202. When a user device 202 desires to communicate with a web server 210, the user device will send a dynamic host configuration protocol (DHCP) request to the network 206. A DHCP server (not shown) connected with the network 206 will issue the user device 202 an internet Protocol (IP) address. The IP address allows the user device 202 to communicate with the web server 210 via the network 206 and proxy server 208 using HTTP or HTTPS.
Depending on the implementation, the context awareness metadata software 222 manages one or more of the proxy server 208, ICAP element 212, position mapper 214, and the location engine 216 to identify the context of the user device 202 and provide context aware metadata.
The ICAP element 212 receives a request for a modified header from the proxy server 208, the request for a modified header to include contextual awareness metadata. The ICAP element 212 then requests the location of the user device 202 from the position mapper 214.
The location engine 216 provides the current location of the user device 202 to the position mapper 214. The location engine 216 can use one or more of triangulation, latency data or access point connection data to detect the current location of the user device 202.
The position mapper 214 receives IP and MAC address information related to the user device 202 from the network 206, and also receives location information related to the user device 202 from the location engine 216. The position mapper 214 uses the IP and MAC address of the user device 202 and the location of the user device 202 to return the location of the user device 102 to the ICAP element 212.
In particular, the position mapper 214 takes the IP address of the user device 202, and requests location information from the location engine 216 based on the MAC address of the user device 202. The position mapper 214 then returns location information to the ICAP element 212, which requested contextual information for the user device 202. In this manner, location information related to the user device 202 is sent back to the ICAP element 212, and the ICAP element 212 provides a modified HTTP header to the proxy server 208 with the location information of the user device 202. The obtaining of the contextual information related to the user device 202 is depicted using the logical connection 256. The proxy server 208 receives the modified header and provides a modified HTTP request to the web server 210, the modified request having the current location of the user device 202, thus allowing the web server 210 to provide contextual content to the user device 202 based on the location of the user device 202.
The apparatus 200 also comprises a number of physical connections and logical connections. The term “physical” connection is meant to include any wired or wireless connection. The term “logical” connection is meant to include a connection that may occur between or among two or more devices without a direct physical connection. The physical connections are shown in solid line while the logical connections are shown in dotted line. Regardless of whether the connections are logical or physical, the connections can be wireless, wired, or any other connection known to those having ordinary skill in the art.
The user device 202 is connected to the network 206 over a wireless connection 232, which is also depicted as a logical connection 251. The proxy server 208 is connected to the network 206 over a physical connection 234. The proxy server 208 is connected to the web server 210 over physical connections 236 and 238. The connections 236 and 238 may also traverse the network 206. The proxy server 208 is also connected to the ICAP element 212 over physical connection 242. The ICAP element 212 is connected to the position mapper 214 over physical connection 244. The position mapper 214 is connected to the location engine 216 over physical connection 246. The physical connections 232, 234, 236, 238, 242, 244 and 246 can be any wired or wireless connections as known to those having ordinary skill in the art.
The web server 210 comprises a content adaptation software element 224 and a content presentation software element 229, a lookup table 225, and a software plug-in 227. The transfer of contextual metadata from the user device 202 to the web server 210 without the interaction of the web browser 204 is also depicted using a logical connection 237.
The apparatus 200 also comprises a database 218 that is logically connected to the user device 202 over logical connection 252. The database 218 includes content aware metadata from sources other than the user device 202.
In the embodiment shown in
In the embodiment shown in
The flow of the context aware metadata described here allows an HTTP client application (such as a web browser) to receive and process the context awareness metadata without requiring local access to the mobile device's sensors, memory, processors, radios, and other context awareness inputs.
In the embodiment shown in
In an embodiment, it is possible to correlate the context aware metadata provided by the application 209 and/or the background process 211 with ordinary web traffic from the web browser 204 so that the web server 210 can recognize that the particular call is originating from the same device (user device 202) that has the application 209 and/or the background process 211 that is providing the contextual awareness metadata. For example, at a time that a page is loaded in the web browser 204, a cookie or other identifier could be passed to the background process 211 using, for example, an AJAX call, such that a web page passes a unique ID of the user device 202 to the background process 211 and to the context server 215. In this manner, when the background process 211 communicates to the context server 215, it can pass the cookie or other identifier that a previous web page/site has established. So at the time a web page access request goes through the proxy server 208, the same cookie or identifier is passed along with the request, the proxy server 208 intercepts it, and passes it to the context server 215 so that the context server 215 can recognize the user of the user device 202.
The diagram 300 illustrates the operation of various elements in
The call 306 illustrates an HTTP request for a website (e.g., www.domain.com) made by the user device 102 and forwarded through the network 106 to the proxy server 108. The call 320 represents IP and media access control (MAC) address mapping between the network 106 and the position mapper 114. To summarize the call 320, the position mapper 114 takes the IP address of the user device 102, and requests location information from the location engine 116 based on the MAC address of the user device 102 received from the network 106. The position mapper 114 then associates the IP address and the MAC address. The position mapper 114 then returns location information to the ICAP element 112, which requested contextual information for the user device 102. In this manner, location information related to the user device 102 is sent back to the ICAP element 112, and the ICAP element 112 provides a modified HTTP header to the proxy server 108 with the location information of the user device 102. In this manner, location information and, to a broader extent, context information related to the user device 102 is added to the HTTP request either explicitly or implicitly.
The call 308 represents the transfer of a request for a modified HTTP header sent from the proxy server 108 to the ICAP element 112. The request for a modified HTTP header is sent from the proxy server 108 over connection 142, and includes context aware metadata pertaining to the context of the user device 102. In an embodiment, the context of the user device can be determined in a number of different ways. In the example shown in
The call 312 issued between the ICAP element 112 and the position mapper 114 is made over connection 144 to determine the position of the user device 102 and to obtain modified header information.
The call 314 made between the position mapper 114 and location engine 116 over connection 146 refers to a first detection of the location of the user device 102. The immediate polling requests improve the user experience by shortening the perceived time to first fix (TTFF). The calls 316 refer to a series of polling intervals and position location fixes that occur in real time between the position mapper 114 and the location engine 116 to determine the location of the user device 102 after the initial request by the call 314. The polling intervals can be any duration, can be configurable, and, in an example, can be one (1) second.
The call 318 attempts to determine whether a threshold is met.
The call 322 fixes the location of the user device 102, whereby the location engine 116 fixes the location of the user device 102 and communicates the location to the position mapper 114. The call 324 is provided from the position mapper 114 to the ICAP element 112 and refers to a “geofenced zone” location. As used herein, a “geofenced zone” location refers to a geographic area that is monitored for the presence of a user device 102 and a user. In an embodiment, such a geofenced zone can comprise an attraction at an amusement facility, a performance venue, or any other area that can be monitored using one or more technologies, such as GPS, radio frequency identification (RFID), video surveillance, etc.
The call 326 issued from the ICAP element 112 to the proxy server 108 over connection 142 provides a modified HTTP header to the proxy server 108. The modified HTTP header includes the context aware metadata and also includes the location of the user device 102.
The call 328 provided from the proxy server 108 to the web server 110 over connection 136 includes a modified HTTP request having context aware metadata and includes the location of the user device 102. The call 332 from the web server 110 to the proxy server 108 over connection 138 includes contextual content that is tailored to the user based on the location and context of the user device 102. The call 334 provided from the proxy server 108 to the mobile device 102 over connections 134 and 132 includes the context aware content delivered to the user device 102, and is also shown for reference as traveling over logical connection 156. In this manner, the context of the user device 102 is determined and contextual content is provided from the web server 110 to the user device 102.
As an example, call 402 represents a dynamic host configuration protocol (DHCP) request sent from the mobile device 202 to the network 206. In response, the network 206 returns a call 404, assigning an Internet Protocol (IP) address to the user device 202, thus allowing the user device 202 to access and communicate over the network 206.
Prior to, or continuously with the user device 202 communicating with the web server 210 via the network 206, the native application 209 issues a call 452 to the context server 215. The call 452 includes contextual metadata that is sent from the native application 209 to the context server 215 outside of the operation of the web browser 204. The call may be initiated by the native application 209, or may be in response to a poll, a request, or some other communication from the context server 215. The call 452 may also incorporate information from the background process 211.
The call 454 sent from the context server 215 to the ICAP element 212 includes a location request pertaining to the user device 202.

The call 406 illustrates an HTTP request for a website (e.g., www.domain.com) made by the user device 202 and forwarded through the network 206 to the proxy server 208. The call 406 includes the contextual information that was received by the user device 202 in the call 460 described above.
The call 420 represents IP and media access control (MAC) address mapping between the network 206 and the position mapper 214. To summarize the call 420, the position mapper 214 takes the IP address of the user device 202, and requests location information from the location engine 216 based on the MAC address of the user device 202 received from the network 206. The position mapper 214 then associates the IP address and the MAC address. The position mapper 214 then returns location information to the ICAP element 212, which requested contextual information for the user device 202. In this manner, location information related to the user device 202 is sent back to the ICAP element 212, and the ICAP element 212 provides a modified HTTP header to the proxy server 208 with the location information of the user device 202. In this manner, location information and, to a broader extent, context information related to the user device 202 is added to the HTTP request either explicitly or implicitly.
The call 408 represents the transfer of a request for a modified HTTP header sent from the proxy server 208 to the ICAP element 212. The request for a modified HTTP header is sent from the proxy server 208 over connection 242, and includes context aware metadata pertaining to the context of the user device 202. In an embodiment, the context of the user device can be determined in a number of different ways. In the example shown in
The call 412 issued between the ICAP element 212 and the position mapper 214 is made over connection 244 to determine the position of the user device 202 and to obtain modified header information.
The call 414 made between the position mapper 214 and location engine 216 over connection 246 refers to a first detection of the location of the user device 202. The immediate polling requests improve the user experience by shortening the perceived time to first fix (TTFF). The calls 416 refer to a series of polling intervals and position location fixes that occur in real time between the position mapper 214 and the location engine 216 to determine the location of the user device 202 after the initial request by the call 414. The polling intervals can be any duration, can be configurable, and, in an example, can be one (1) second. The call 418 attempts to determine whether a threshold is met.
The call 422 fixes the location of the user device 202, whereby the location engine 216 fixes the location of the user device 202 and communicates the location to the position mapper 214.
The call 424 is provided from the position mapper 214 to the ICAP element 212 and refers to a “geofenced zone” location. As used herein, a “geofenced zone” location refers to a geographic area that is monitored for the presence of a user device 202 and a user. In an embodiment, such a geofenced zone can comprise an attraction at an amusement facility, a performance venue, or any other area that can be monitored using one or more technologies, such as GPS, radio frequency identification (RFID), video surveillance, etc.
The call 426 issued from the ICAP element 212 to the proxy server 208 over connection 242 provides a modified HTTP header to the proxy server 208. The modified HTTP header includes the context aware metadata and also includes the location of the user device 202.
The call 428 provided from the proxy server 208 to the web server 210 over connection 236 includes a modified HTTP request having context aware metadata and includes the location of the user device 202.
The call 432 from the web server 210 to the proxy server 208 over connection 238 includes contextual content that is tailored to the user based on the location and context of the user device 202.
