     DETAILED DESCRIPTION 
     A detailed description of the systems and methods consistent with embodiments of the present disclosure is provided below. While several embodiments are described, it should be understood that the disclosure is not limited to any one embodiment, but instead encompasses numerous alternatives, modifications, and equivalents. In addition, while numerous specific details are set forth in the following description in order to provide a thorough understanding of the embodiments disclosed herein, some embodiments can be practiced without some or all of these details. Moreover, for the purpose of clarity, certain technical material that is known in the related art has not been described in detail in order to avoid unnecessarily obscuring the disclosure. 
     The embodiments of the disclosure may be understood by reference to the drawings, wherein like parts may be designated by like numerals or descriptions. The components of the disclosed embodiments, as generally described and illustrated in the figures herein, could be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the systems and methods of the disclosure is not intended to limit the scope of the disclosure but is merely representative of possible embodiments of the disclosure. In addition, the steps of any method disclosed herein do not necessarily need to be executed in any specific order, or even sequentially, nor need the steps be executed only once, unless otherwise specified. 
     Consistent with embodiments disclosed herein, personal information relating to a user may be obtained and used in connection with efficiently targeting information to a particular user and/or content tagging operations. Such personal information may include, without limitation, usage information relating to usage devices associated with a user, environmental information obtained from sensors included in such devices, user volunteered personal information, and/or a measure of the user&#39;s emotional state and/or mood obtained based on associated contextual information. Based on such information, a user&#39;s interests at a given time may be inferred, and matched content, search results, and/or other information may be targeted for delivery to the user. Similarly, content generated, and/or viewed by a user may be tagged with personal information associated with a user including, without limitation, information relating to an emotional state and/or mood of a user at the time they viewed and/or captured the content. 
     Embodiments disclosed herein may be used in connection with a variety of information targeting systems and methods. For example, the systems and methods described herein can, for example, be used in connection with advertisement matching and/or advertisement targeting technologies such as those described in commonly assigned co-pending U.S. patent application Ser. No. 12/785,406, filed May 21, 2010 (“the &#39;406 application”), which is incorporated herein by reference in its entirety. 
     Personal information related to a user may be obtained in a variety of ways, including through monitoring user interactions with devices and services. For example, demographic information about the user (e.g., age, gender, etc.), usage history and preferences of the user, information about the user&#39;s device, content preference information (e.g., preferred genres, artists, etc.), information about the user or the user&#39;s environment (e.g., time of day, global positioning system (“GPS”) coordinates, etc.), and/or any other available information relating to a user and/or an associated device may be obtained. In some circumstances, this personal information may be volunteered directly by a user. For example, when registering a device, a user may voluntary provide personal demographic information to a device manufacturer and/or service provider. 
     Consistent with embodiments disclosed herein, personal information related to a user may further comprise contextual information indicative of a user&#39;s mood and/or emotional state, generally referred to herein as emotional context information and/or contextual information. For example, information relating to a user&#39;s voice (e.g., a tone, decibel level, content of speech, and/or the like) may be used to infer a mood and/or emotional state associated with a user (e.g., happy, sad, angry, hungry, excited, etc.). Image and/or video information relating to a user&#39;s facial expressions may also be used to infer an associated mood and/or emotional state of the user. In yet further embodiments, information relating to certain physiological responses of a user including, for example, heart rate, blood pressure, temperature, perspiration, and/or the like (e.g., obtained using wearable health monitoring devices and/or the like), may also be used to infer an associated mood and/or emotional state of the user. 
     As discussed above, personal information provided by a user and/or generated based on a user&#39;s activities may, among other things, be utilized to effectively match information including, without limitation, advertisements, content, and/or search results, to the interests of the user. This may be achieved utilizing, for example, the ad-matching technologies described in the &#39;406 application. In certain embodiments, information matching may be performed locally on a user&#39;s device. Alternatively, information—matching may performed by a trusted third party and/or a content or search service. Further, in circumstances where a user utilizes multiple devices and/or services to consume content, personal information may be managed, shared, and/or aggregated between the devices and/or services to generate a more detailed and accurate profile of the user&#39;s interests. By improving the ability to generate a more detailed profile of a user&#39;s interests, managing personal information related to the user between multiple devices can improve information matching services. 
     In the context of managing, sharing, and aggregating personal information between multiple devices and/or services, the confidentiality of certain private personal information related to the users may be maintained. For example, a user may wish to not have an audio and/or video recording of themselves transferred to third-party systems and/or untrusted services from their local user devices. Accordingly, systems and methods may be deployed that allow for managing the confidentiality of user personal information. In some embodiments, this may be achieved by ensuring that certain personal information is not communicated outside of a user&#39;s device, devices, and/or a trusted boundary associated with the user. Additionally, anonymous and/or anonymized versions of personal information may be generated that can be managed, shared, and aggregated between multiple devices and/or services without compromising user privacy. Further, users may specifically restrict access to certain categories and/or types of personal information, while allowing the sharing and aggregating of other types of personal information through one or more articulated policies. Employing such techniques may allow for improved information matching services while maintaining the confidentiality of certain user personal information. 
     In further embodiments, the disclosed systems and methods may facilitate association of generated and/or rendered content with relevant emotional context information. When content is generated and/or otherwise captured by user device, the generated content may be associated with available emotional context information relating to a user, thereby providing an indication of a user&#39;s emotional state and/or mood when the content was generated. For example, a captured photograph may be associated with emotional context information including information relating to a user&#39;s voice captured by a microphone and philological information captured by a biometric sensor, thereby providing a way to search and/or otherwise identify a user&#39;s emotional state and/or mood when the photograph was taken. In further embodiments, emotional states and/or moods inferred based on the emotional context information may be associated with the generated and/or rendered content. 
       FIG. 1  illustrates information targeting using emotional context information consistent with embodiments of the present disclosure. In certain embodiments, a user device  100  may interact with a trusted service  102  and/or a content/search service  104 .

     The user device  100 , trusted service  102 , and/or content/search service  104  may comprise a computing device executing one or more applications configured to implement embodiments of the systems and methods disclosed herein. In certain embodiments, the user device  100  may comprise at least one of a smartphone, a smartwatch, a laptop computer system, a desktop computer system, a gaming system, an entertainment system, a streaming media system, a wearable health monitoring device, a tablet computer, a smart home device, a digital assistant device, a connected appliance, and/or any other computing system and/or device that may be used in connection with the disclosed systems and methods. In certain embodiments, the user device  100  may comprise software and/or hardware (e.g., emotional context information sensors  108 ) configured to, among other things, obtain personal information  108  including contextual information relating to a user&#39;s moods and/or emotional states, infer moods, emotional states, and/or interests of the user based on such personal information  108 , and/or match information to the moods, emotional states, and/or interests of the user. 
     The user device  100 , trusted service  102 , and/or content/search service  104  may communicate using a network comprising any suitable number of networks and/or network connections. The network connections may comprise a variety of network communication devices and/or channels and may use any suitable communication protocols and/or standards facilitating communication between the connected devices and systems. For example, in some embodiments the network may comprise the Internet, a local area network, a virtual private network, and/or any other communication network utilizing one or more electronic communication technologies and/or standards (e.g., Ethernet and/or the like). In some embodiments, the network connections may comprise a wireless carrier system such as a personal communications system (“PCS”), and/or any other suitable communication system incorporating any suitable communication standards and/or protocols. In further embodiments, the network connections may comprise an analog mobile communications network and/or a digital mobile communications network utilizing, for example, code division multiple access (“CDMA”), Global System for Mobile Communications or Groupe Special Mobile (“GSM”), frequency division multiple access (“FDMA”), and/or time divisional multiple access (“TDMA”) standards. In certain embodiments, the network connections may incorporate one or more satellite communication links. In yet further embodiments, the network connections may use IEEE&#39;s 802.11 standards, Bluetooth®, ultra-wide band (“UWB”), Zigbee®, and or any other suitable communication protocol(s). 
     As discussed above, information services, including search, content, recommendation, and/or advertisement services, may engage in a variety of activities to improve delivery of their services. For example, a search service  104  may use search engine indexing information, ranking information, and cookie information to analyze a user&#39;s past search history and to improve future search results. Recommendation and/or advertisement services may use cookies, mobile device sensor information (e.g., installed application information, geolocation information, etc.) to analyze a user to improve targeting of delivered recommendations and/or advertisements. In many instances, information services may use input from a user (e.g., search terms) combined with analytics relating to a user&#39;s past behavior. 
     As a user interacts with a user device  100  (e.g., consumes and/or generates content and/or interacts with applications and/or services) and/or services, the device  100  and/or services may obtain personal information  108  relating to the user. In certain embodiments, this personal information  108  may reflect in part the interests of the user. Personal information  108  may include, among other things, information volunteered by a user (e.g., declared interests) and/or information collected by monitoring a user&#39;s activities in connection with an associated device (e.g., device activity information). For example, a user may provide a device  100  with personal identification information (e.g., age, gender, home address, and the like) and/or other preference information (e.g., content preference information including preferred genres, artists, and the like). Similarly, a device  100  may passively collect usage information regarding the types of content a user consumes, the number of times certain content is consumed, application usage information, location-based information relating to a location of the user, and/or the like. Collectively, personal information  108  may include, without limitation, user attributes such as gender, age, content preferences, geographic location, attributes and information associated with a user&#39;s friends, contacts, and groups included in a user&#39;s social network, and/or information related to content and/or application usage patterns including what content is consumed, content recommendations, advertisement viewing patterns, and the like. 
     Certain personal information  108  may be volunteered (e.g., provided directly) by a user. For example, when registering or configuring a device  100 , a user may voluntarily provide personal demographic information to the device  100 , a device manufacturer, and/or a service provider. In certain embodiments, this information may include a user&#39;s age, gender, contact information, address, field of employment, and/or the like. User-volunteered personal information may also include content preference information (e.g., preferred genres, preferred artists, etc.). In some embodiments, in lieu of or in addition to collecting personal information as part of a device registration or configuration process, user-volunteered personal information may be provided by a user when registering with a service or at various times during a user&#39;s interaction with a device  100  (e.g., concurrent with selection of a particular piece of content, using a particular application, and/or the like). 
     In further embodiments, personal information  108  may comprise one or more certified attributes acquired from one or more trusted sources that can authenticate certain attributes relating to the user and/or the user device  100  (e.g., attributes relating to age, gender, education, club membership, employer, frequent flyer or frequent buyer status, credit rating, etc.). The user device  100  may also generate and/or collect other attributes from various user events as personal information  108  including, for example, metrics or attributes derivable from a user&#39;s history of interactivity with ads, purchasing history, browsing history, content rendering history, application usage history, and/or the like. Further, a variety of environmental attributes may also be included in personal information  108  such as time of day, geographic location, speed of travel, and/or the like. 
     Personal information  108  may further include information collected by monitoring a user&#39;s activities in connection with an associated device  100  and/or services (e.g., device activity information and/or usage data). Usage data may include information regarding the types of content a user consumes, the number of times certain content is consumed, metrics or attributes derived from a user&#39;s history of interactions with ads and/or content, information regarding application usage, application usage history, purchasing history, browsing history, content rendering history, and/or the like. In certain embodiments, usage data may be generated locally on a user&#39;s device  100  through monitoring of a user&#39;s interaction with the device  100 . Alternatively or in addition, usage data may be generated by a trusted third party capable of monitoring a user&#39;s interaction with a device  100 . In some embodiments, usage data may be stored locally on a user&#39;s device  100  in a secure manner to protect the integrity of the data and/or be filtered suitably to ensure that it is anonymized in some way before it is transmitted from the device  100 . 
     Consistent with the disclosed embodiments, information services may utilize certain dynamic contextual information or emotional context information in connection with delivery of their services. For example, contextual information indicative of a user&#39;s interests, moods, and/or emotional states and a given time, may prove valuable in targeting well-matched information to the user. In some embodiments, such contextual information may be collected using one or more sensors  106  included in devices  100  associated with the user. Device sensors  106  configured to generate contextual information may include, without limitation, one or more video and/or image sensors such as a camera, audio capture sensors such as a microphone, various biometric information configured to capture information relating to one or more physiological responses of a user, light sensors configured to sense an amount of light incident on at least a portion of the user device  100 , pressure sensors configured to sense an amount of pressure applied to a touch screen and/or other device interface, and/or the like. In some embodiments, the device sensors  106  may not necessarily be integrated within the device  100 , but may be obtained via one or more communicatively-linked associated peripheral devices such as a health monitoring device and/or the like. 
     Contextual information, including contextual information generated by the emotional context information sensors  106 , may comprise, without limitation, audio information relating to a user&#39;s voice (e.g., tone, decibel level, ambient background noise, recognized speech content, etc.), image and/or video information relating to a user&#39;s facial expressions (e.g., facial expression recognition information, iris dilation, etc.), biometric and/or physiological information (e.g., heart rate, blood pressure, temperature, perspiration, etc.), other sensor data (e.g., interface/display pressure sensor data, light sensor data, etc.), and/or any other relevant information indicative of a user&#39;s emotional state and/or mood (e.g., usage of emoji&#39;s and/or other ideograms, etc.). 
     In certain embodiments, contextual information may be used to infer a variety of moods and/or emotional states of a user including, without limitation, anger, contempt, disgust, fear, happiness, indifference, love, sadness, surprise, and/or the like. Inferred moods and/or emotional states may be associated with certain quantified weights and/or metrics indicating a relative likelihood that a user is experiencing a particular mood and/or emotional state based on the associated contextual information. For example, the louder a user&#39;s voice, the more likely they are to be feeling anger.  FIG. 2  illustrates an example of various moods and/or emotional states and associated contextual information that may be used to infer an associated mood and/or emotional state. It will be appreciated that a variety of other emotional states and/or types of contextual information may be used in connection with the disclosed embodiments, and that any suitable association between contextual information and emotions states may be used. Thus it will be appreciated that the various relationships illustrated in connection with  FIG. 2  are presented for explanation purposes, and that other relationships between emotional states and contextual information may be used in connection with the disclosed embodiments. 
     Referring back to  FIG. 1 , the user device  100  may transmit personal information  108  relating to the user of the device to a trusted service  102 . The trusted service  102  may provide certain functions associated with an information targeting platform such as that described in the &#39;506 application. In some embodiments, based on received personal information  108 , the trusted service  102  may populate a profile  112  associated with a user of the user device  100 . The profile  112  may comprise a variety of personal information  108  and/or interests, moods, and/or emotional states inferred based on the personal information  108 . Information included in the profile  112  may allow information service providers (e.g., a content/search service) to provide to provide a more personalized and targeted experience for users. 
     In some embodiments, the trusted service  102  may operate in conjunction with the user device  100  and information service providers to provide certain targeted information services. In certain embodiments, the trusted service  102  may function as a trusted intermediary between the user device and an information service, such as the content/search service  104 . For example, as illustrated, the trusted service  102  may receive content and/or search information  114  from the content and/or search service. Based on information included in the user profile  112  (e.g., indications of user interests, moods, and/or emotional states) and the received content and/or search information  114 , the trusted service  102  may match content and/or search results to a user&#39;s interests and transmit matched content and/or search results  110  to the user device. 
     In one example, a user may be interested in watching a romantic movie, and may use a search service to find a movie title that interests them. The user may provide the keyword “romantic movie,” but such a simplistic search may not necessarily reflect what the user&#39;s emotional state was at the time the keyword was provided. If an audible search command for “romantic movie” is provided, however, contextual information that may be derived from the tone of the user&#39;s voice may provide information relating to how they felt at the time the search command was issued (e.g., angry, sad, lonely, etc.). Such emotional state information may be weighted and/or otherwise quantified based on analysis of the associated contextual information. For example, one or more scores associated with the derived emotional states (e.g., 0.1 angry, 0.6 sad, 0.3 lonely, etc.) may be generated indicative of a relative likelihood the user is experiencing a particular emotion and/or the relative degree of an experienced emotion. 
     The search service  104  may have information included in an indexed catalog of romantic movies indicating feedback from others regarding how they felt following watching movies included in the catalog (e.g., marketing research data). In some embodiments, the feedback may comprise weighted, quantified, and/or otherwise scored information relating to emotional states associated with the included movies (e.g., 0.3 angry, 0.4 sad, 0.3 lonely, etc.). Based on a comparison between such indexed information and the emotional state information associated with the user, the search service  104  may return a movie recommendation that best matches the user&#39;s emotional state inferred based on the contextual information. 
     Various aspects of the disclosed embodiments may protect user privacy. For example, if a user is concerned about sending their raw voice recording data to the trusted service  102  and/or the search engine service  104 , the raw voice recording data may be analyzed locally on the user&#39;s device  100  to determine any associated weighted and/or otherwise parameterized mood and/or emotional state information. This weighted mood and/or emotional state information may then be provided to the trusted service  102  and/or the search engine service  104  instead of the raw voice recording, thereby providing a measure of privacy for the user. In yet further embodiments, certain weighted information may remain local to a user&#39;s device  100 , and a trusted service  102  and/or information service may send several candidate movie search results to the user device  100  for local matching with the weighted mood and/or emotional state information. 
     In another example, an advertiser may wish to display a commercial and/or advertisement targeted to a user&#39;s interest while they are viewing a program on their television. Image and/or video information obtained by the television and/or another associated device (e.g., a gaming console with a camera and/or the like) may capture a user&#39;s face expression at a particular time, which may be used to infer the user&#39;s emotional state and/or mood consistent with embodiments disclosed herein. The state and/or mood information may be weighted based on analysis of the associated image and/or video information (e.g., 0.2 hungry, 0.5 happy, 0.3 excited, etc.). Advertisements and/or commercials may be associated with particular emotional states and/or moods by a content provider, and may be matched to particular users based in part on the inferred state and/or mood information. 
     If a user is concerned about sending raw images or video of their face to the advertising service, the raw images or video may be analyzed locally on the user&#39;s device  100  to determine any associated weighted mood and/or emotional state information. This weighted mood and/or emotional state information may then be provided to the advertiser instead of the raw images or video recording, thereby providing a measure of privacy for the user. In yet further embodiments, certain weighted information may remain local to a user&#39;s device  100 , and an advertiser may send several candidate advertisements to the user device  100  for local matching with the weighted mood and/or emotional state information. 
     It will be appreciated that a number of variations can be made to the architecture, relationships, and examples presented in connection with  FIG. 1  within the scope of the inventive body of work. For example, certain device and/or system functionalities described above may be integrated into a single device and/or system and/or any suitable combination of devices and/or systems in any suitable configuration. Thus it will be appreciated that the architecture, relationships, and examples presented in connection with  FIG. 1  are provided for purposes of illustration and explanation, and not limitation. 
       FIG. 3  illustrates an exemplary device architecture for associating content  310  with emotional context information consistent with embodiments disclosed herein. As illustrated, a user device  100  may comprise one or more emotional context information sensors  106  configured to generate and/or otherwise capture contextual information relating to a user&#39;s emotional state and/or mood. The emotional context information sensors may include, without limitation, one or more video and/or image sensors such as a camera  300 , audio capture sensors such as a microphone  304 , various biometric sensors  302  configured to capture information relating to one or more physiological responses of a user, light sensors configured to sense an amount of light incident on at least a portion of the user device  100 , pressure sensors configured to sense an amount of pressure applied to a touch screen and/or other device interface, and/or the like. As discussed above, in some embodiments, the device sensors  106  may not necessarily be integral to device  100 , but may be associated with one or more peripheral devices in communication with the user device  100 , such as a health monitoring device (e.g., a wireless heartrate monitor) and/or the like. 
     A variety of software modules  306 ,  308  may be executed by the user device  100  to facilitate user interaction with content  310 . In some embodiments, one or more content capture modules  306  may be configured to capture and/or otherwise generate content using the device  100  (e.g., image content  310 ). For example, the one or more content capture modules  306  may comprise a camera and/or audio recording application confirmed to enable a user to capture video content, image content  310 , and/or audio content using the user device. In further embodiments, one or more content rendering modules  308  may be configured to allow a user to view, render, and/or otherwise interact with content using the device  100 . For example, a content rendering module  308  may allow a user to view video content, image content  310 , and/or playback audio content. 
     Consistent with embodiments disclosed herein, content  310  generated and/or rendered by user the user device  100  may be associated with contextual information generated by the one or more emotional context information sensors  106 . In some embodiments, when content is generated and/or rendered by the user device  100 , various contextual information generated by the one or more emotional context information sensors  106  may be included metadata  312  associated with the content  310 . For example, as illustrated, when capturing and/or rendering image content, an associated content file  310  may be tagged and/or otherwise associated with metadata  312  that comprises biometric response information, audio response information, image and/or video response information, and/or the like generated by the emotional context information sensors  106  at the time the content was captured and/or rendered by the device  100 . In this manner, the metadata  312  information may include information representative of a user&#39;s state and/or mood when the content file  310  was captured and/or rendered by the device  100 . 
     In some embodiments, based on analysis of associated contextual information generated by emotional context information sensors  106 , emotional states and/or moods associated with the user and/or content file  310  may be inferred. Such inferred emotional response information may further be included in the content metadata  312 . As discussed above, inferred emotional response information may comprise weighted, scored, and/or otherwise quantified indications of likely user emotional states and/or moods. In some embodiments, to preserve user privacy, inferred emotional response information may be included in the content metadata  312  without including raw contextual information. 
     Associating contextual information and/or inferred emotional response information in content metadata may allow for users to interact with generated and/or rendered content files  310  in a variety of ways. In some embodiments, content generated and/or rendered by a device  100  may be searched, indexed, and/or organized, based on the associated emotional state and/or mood experienced by a user when the content was captured and/or rendered. For example, a user may wish to view content that, when viewed previously by the user, caused the user to feel happy. Similarly, a user may wish to view content that, when captured by the user using their device  100 , made the user feel euphoric. 
       FIG. 4  illustrates an exemplary method  400  for associating contextual information with content consistent with embodiments of the present disclosure. The illustrated method  400  may be implemented in a variety of ways, including using software, firmware, hardware, and/or any combination thereof. In certain embodiments, the method  400  may be implemented by an electronic device associated with a user. 
     At  402 , content may be generated and/or rendered using a user device. For example, image content may be captured by a camera included in and/or otherwise associated with a user device. In another example, video content may be rendered on a user device via an associated display. 
     Emotional context information may be received from one or more emotional context information sensors included in the user device and/or other devices and/or systems associated with the user device at  404  (e.g., systems in communication with the user device that include emotional content information sensors). As discussed above, the emotional context information may include, without limitation, one or more of audio information relating to a user&#39;s voice (e.g., tone, decibel level, ambient background noise, recognized speech content, etc.), image and/or video information relating to a user&#39;s facial expressions (e.g., facial expression recognition information, iris dilation, etc.), biometric and/or physiological information (e.g., heart rate, blood pressure, temperature, perspiration, etc.), other sensor data (e.g., pressure sensor data, light sensor data, etc.), and/or any other relevant information indicative of a user&#39;s emotional state and/or mood (e.g., usage of emoji&#39;s and/or other ideograms, etc.). 
     In some embodiments, the emotional context information received at  404  may be captured at a time the content was generated and/or rendered at  402  and/or within a certain time period of the content being generated and/or rendered at  402 . In this manner, the emotional context information received at  404  may be reflective of a user&#39;s emotional state and/or mood when the content was generated and/or rendered. 
     At  406 , the content generated and/or rendered at  402  may be associated with the emotional context information received at  404 . For example, the emotional context information received at  404  may be included in metadata associated with the generated and/or rendered content. In some embodiments, based on analysis of the emotional contextual information received at  402 , emotional states and/or moods associated with the user may be inferred. Such inferred emotional response information may further be associated with the content generated and/or rendered at  402 . As discussed above, inferred emotional response information may comprise weighted, scored, and/or otherwise quantified indications of likely user emotional states and/or moods. In this manner, the content may be searched, indexed, and/or organized based on associated emotional states and/or moods experienced by the user when the content was created and/or rendered. 
       FIG. 5  illustrates an exemplary method  500  for emotional response targeting using contextual information consistent with embodiments of the present disclosure. The illustrated method  500  may be implemented in a variety of ways, including using software, firmware, hardware, and/or any combination thereof. In certain embodiments, various aspects of the method  500  may be implemented by an electronic device associated with a user, a trusted service, and/or a content and/or targeting service. 
     Various embodiments disclosed herein may use emotional context information associated with content to target and/or evoke a particular emotional response in a user. Emotional context information may be received from one or more emotional context information sensors included in a user device and/or other devices and/or systems associated with the user device at  502 . The emotional context information may include, for example, one or more of audio information relating to a user&#39;s voice, image and/or video information relating to a user&#39;s facial expressions, biometric and/or physiological information, other sensor data, and/or any other relevant information indicative of a user&#39;s emotional state and/or mood. 
     Based on the emotional context information received at  502 , a current emotional state and/or mood associated with the user may be inferred and/or otherwise determined at  504 . In some embodiments, inferred emotional response information may comprise weighted, scored, and/or otherwise quantified indications of likely user emotional states and/or moods based on the emotional context information. 
     At  506 , an indication of a target emotional state and/or mood may be received. Content may be identified at  508  configured to evoke a target emotional response in a user. That is, at  508 , content may be identified which when rendered is likely to cause a user&#39;s current emotional state and/or mood determined at  504  to change to the target emotional state and/or mood specified by the indication received at  506 . 
     In some embodiments, the content may be identified at  508  independent of the current emotional state and/or mood of the user determined at  504 . For example, the content may be identified at  508  by simply analyzing metadata associated with available content that includes emotional context information to identify metadata matches and/or is similar within a certain degree and/or threshold to emotional context information that is associated with the target emotional state and/or mood specified by the indication received at  506 . 
     In further embodiments, the identification of the content at  508  may be based on the current emotional state and/or mood of the user determined at  504  and the targeted emotional state and/or mood of the user specified by the indication received at  506 . For example, content may selected to evoke a transition from a specific first emotional state and/or mood to a targeted emotional state and/or mood (e.g., sad to happy). In this manner, content may be identified at  508  that designed to evoke a particular transition to a target emotional state and/or mood of a user. 
     The content identified at  508  may be rendered to a user at  510 . During and/or following rendering of the content, emotional context information may be received associated with the user at  512 . In some embodiments, emotional context information received at  512  may be used to infer and/or otherwise determine the influence of the content rendered at  510  on the emotional state and/or mood of the user. At  514 , a determination may be made regarding whether the emotional context information received at  512  is similar within a certain degree and/or threshold to emotional context information that is associated with the target emotional state and/or mood specified by the indication received at  506 . If so, an associated indication may be send to an interested entity and the method  500  may proceed to end. 
     If the emotional context information received at  512  is not similar within a certain degree and/or threshold to emotional context information that is associated with the targeted emotional state and/or mood specified by the indication received at  506 , the method  500  may return to  508 , where content may be identified based on the emotional context information received at  512 . In this manner, content may be iteratively identified at  508  and rendered at  510  until a desired user emotional state and/or mood is achieved. 
     Embodiments of the disclosed method  500  may be implemented in a variety of contexts. For example, a restaurant may wish to evoke a romantic mood in its patrons. The restaurant may thus wish to play music that is tagged and/or otherwise associated with emotional context information associated with a romantic emotional state. Emotional context information associated with restrauant patrons may be collected (e.g., via cameras, microphones, and/or other emotional context information sensors associated with an environment of the patrons and/or devices associated with the patrons), and the collected information may be used to identify content that when rendered in the restaurant may evoke the desired emotional response. In some circumstances, selected content may be dynamically updated based on feedback from real-time measured emotional context information associated with a target audience. 
     In another example, a performance event may wish to encourage an audience to feel a particular way (e.g., euphoric). Accordingly, the event may play video content that that is associated with a target emotional state associated with the desired audience feelings. In some circumstances, selected content may be dynamically updated based on real-time measured emotional context information associated with a target audience.
