Abstract:
Increasingly, children are consuming digital content on computers, laptops, tablets, and even smartphones. The sheer volume of content available to children can be daunting for parents to manage and filter for their children. Primitive filtering mechanisms based on a target audience age can be used to eliminate some content based on a child&#39;s chronological age. However, children develop at different rates so that even children of the same chronological age can have different developmental stages and so have different preferences for content they consume. Systems and methods described herein provide children with access to developmental stage-appropriate content in a developmental stage-appropriate user interface. The developmental stage-appropriate interface includes representations of the content that are developmental stage-appropriate and surrounding elements that are also developmental stage-appropriate. The user interface can include or not include functional elements based on the developmental stage of the user.

Description:
BACKGROUND 
       [0001]    1. Field 
         [0002]    This U.S. patent application relates generally to presenting age-appropriate content in a user interface. 
         [0003]    2. Description of Related Art 
         [0004]    Online content providers have large libraries containing hundreds, if not thousands, of items of content available to content consumers. For special populations, such as children, some of this content can be inappropriate and is typically blocked from members of those populations. Even regarding the content that is not blocked, some of the allowed content can be inappropriate for certain members of the population. For instance, among children, content targeted to adolescents is inappropriate for toddlers. Further, adolescents may react unfavorably to being shown content targeting toddlers. 
         [0005]    It is generally accepted that children develop according to a known sequence of stages. However, individual children advance through these stages at different rates. Some children may advance so quickly that they appear to skip certain stages while others may appear to be stuck in a particular stage for a longer than normal period of time. Thus, two children at the same chronological age can be at very different stages of development. Further, the same child may be at one developmental stage in one area of development (e.g., communication skills) but at another stage in another area of development (e.g., fine motor control). Herein, the term, “developmental stage” refers to the current developmental stage(s) of the child. The developmental stage does not necessarily correspond to the chronological age of the child. 
         [0006]    Content is targeted to children according to chronological age. However, it is well known that children consume content targeted outside of their chronological age. Further, as discussed above, the chronological age of the child does not necessarily reflect the developmental stage of the child.

     DETAILED DESCRIPTION 
       [0023]    Systems and methods of selecting and presenting content, and more particularly representations of content, to child users based on developmental stage are described. To determine a developmental stage of a child, the system provides an input element that allows a parent or child user to select the child&#39;s developmental stage as a point in, or a portion of, a continuous range of childhood stages. In some instances, the developmental stage of the child may be determined based on viewing history or an operating context of the user. Content is selected for the user based on the developmental stage of the user. The user is then presented with representations of the content. The representations can then be selected in order to view or receive the content. 
         [0024]    More particularly, a display is generated that is tailored to the developmental stage of the user. The generated display includes representations of the content pre-determined to be appropriate for the developmental stage of the user. Further, other display elements, such as background graphics, positions and style of the graphics, and the inclusion or exclusion of interface elements predetermined to be appropriate for the developmental stage are generated. As such, the generated display is tailored to the developmental stage of the user, including which content is selected, how the selected content is represented in the display, and the look and feel of the display itself. By interacting with the display, the user can select content to consume. 
         [0025]    Referring now to  FIG. 1 , an example environment  100  is shown in which various embodiments can be implemented. The environment  100  comprises a content manager  102  and a content server  104  that are configured to communicate over a network  106  with one or more client devices  108 . 
         [0026]    The content manager  102  identifies content that can be made available to the client devices  108  and presents the content in a generated display. The content manager  102  selects content based on a number of factors including developmental stage of the user. The content manager  102  can maintain a user profile that includes information about the user, such as demographic information or information about the client devices  108  used by the user. The content manager  102  can further maintain a viewing history that identifies content that has already been consumed by the user. 
         [0027]    The content server  104  stores or otherwise accesses items of content selected by the user for viewing on the client device  108 . The content can be television shows, movies, music, games, images, audio programs, or other types of digital content. In response to the user selection, the content server  104  delivers the content to the client device  108 . 
         [0028]    In some instances, the content manager  102  and the content server  104  are co-operated and/or co-managed by a same entity. In some embodiments, the functionalities of the content manager  102  and the content server  104  are co-located and/or combined. 
         [0029]    The client device  108  can be used by a single user or by more than one user to choose content for consumption. The client device  108  can be any of a number of consumer devices such as, but not limited to, a smartphone, a tablet, a netbook, a laptop computer, a desktop computer, a gaming console, a set-top box, a television or some combination of these devices. In some instances, a user may habitually use more than one of the client devices  108 . 
         [0030]    Referring now to  FIG. 2 , a block diagram is shown of the content manager  102 , according to some embodiments. The content manager  102  comprises a tagging module  202 , a content tags database  204 , a viewing history database  206 , a developmental stage determination module  208 , a content selection module  210 , a content representation selection module  212 , a layout module  214 , a character bar module  216 , and a stage advancement module  218 . The content manager  102  can be implemented in a variety of ways known to those skilled in the art including, but not limited to, as a computing device having a processor with access to a memory capable of storing executable instructions for performing the functions of the described modules. The computing device can include one or more input and output components, including components for communicating with other computing devices via a network (e.g., the network  106 ) or other form of communication. The content manager  102  comprises one or more modules embodied in computing logic or executable code such as software. 
         [0031]    The tagging module  202  is configured to tag content with metadata tags. Each item of content can have more than one metadata tag. Each metadata tag includes a target consumer age that indicates the chronological age of children who typically consume that content or to whom the content is targeted. Along with the chronological age, in some embodiments the tag includes a relevance of the chronological age to the content. The relevance indicates the likelihood that children of that chronological age, or range of chronological ages, are likely to select and consume the content. The relevance is quantitative. Examples of relevance include, but are not limited to, a numerical weighting factor, a percentage, or other calculated or pre-determined value. 
         [0032]    The metadata tag can be generated by the tagging module  202  based on, for example, information received from the content server  104  or a third party source. The information can include a description of the content provided by a content producer. In other instances, the metadata tag can be generated based on viewing histories of users having a known developmental stage or chronological age. For example, one item of content can include three metadata tags: “ages 6-7, relevance 50%”; ages 8-9, relevance 90%”; and “ages 10-11, relevance 50%”. This item of content is most relevant to children of chronological ages 8-9 but can be enjoyed by children who are aged 6-7 or 10-11 as well. 
         [0033]    In some instances, the metadata tags, or a portion of the metadata tags, can be provided by a third party. The third party can provide, for example, the target chronological age assigned to the content by a content producer. The tagging module  202  can modify the provided tags (e.g., add a relevance to a provided tag that includes a chronological age) and/or add additional metadata tags to the content. 
         [0034]    The metadata tags along with identifiers of the content are stored in the content tag database  204 . The content tag database  204  can be accessed by the tagging module  202  to retrieve and update tags or to store newly generated tags. As described herein, the other modules within the content manager  102  can access metadata tags in the content tag database  204 . 
         [0035]    A viewing history database  206  stores a record of content previously consumed by the user. The viewing history database  206  can include additional information such as a user identifier, a time and/or date indicating when the content was consumed, and an operating context of the user at the time the content was consumed. The operating context can include, for example, the time of day the content was consumed, a geographic location of the client device  108  when the content was consumed, or an identification or description of the client device  108  used to consume the content. 
         [0036]    The developmental stage determination module  208  is configured to determine the developmental stage of the user. As discussed above, the developmental stage of the user is separate from the chronological age in that children can develop at different rates so that two children of the exact same chronological age can often be at different developmental stages. 
         [0037]      FIGS. 5-7  depict portions of a generated display (e.g., a graphical user interface or “GUI”) presenting representations of content to a child user at a first, second, and third developmental stage, respectively. The developmental stage determination module  208  can determine the developmental stage of the user via input from an interface element, such as a position of a slider  504  on a slider bar  502  depicted in  FIGS. 5-7 . Other examples of interface elements include, but are not limited to, a stage selector dial, a stage selector tab that opens like a drawer with a tap, selectable tabs or buttons, a pop-up menu, and a pull-down menu. 
         [0038]    The interface element defines a range of developmental stages, including a predefined minimum and maximum developmental stage. The interface element allows the user to adjust the input, within the defined range, corresponding to the developmental stage of the user. The interface element can allow for continuous (or substantially continuous) selection or offer a pre-determined, limited number of discrete stage choices. 
         [0039]    As the input changes, the generated display  500  can morph on the fly to display different representations of content that correspond to the input determined developmental stage. In other embodiments, the generated display  500  is updated upon the user refreshing the generated display after selecting a stage. The user, based on the representations and the generated display, can provide his closest approximate developmental stage. 
         [0040]    For example, referring now to  FIG. 5 , when the slider  504  is in a first position along slider bar  502 , indicating that the user has a developmental stage corresponding to an infant by virtue of being proximate to a depiction of an infant  510 , the generated display  500  is tailored to a younger audience as discussed in greater detail below. 
         [0041]    Furthering the example, referring now to  FIG. 6 , the slider  504  in the generated display  500  is moved to a second position along the slider bar  502 , indicating that the user has a developmental stage corresponding to a toddler by virtue of being positioned proximate to a depiction of a toddler  512 . As shown in the figure, the generated display  500  has changed to reflect the developmental stage indicated by the position of the slider  504  along the slider bar  502 . 
         [0042]    Furthering the example even more, referring now to  FIG. 7  the slider  504  is in a further position along slider bar  502  thus indicating that the user is of an adolescent developmental stage by virtue of being proximate to a depiction of an adolescent  514 . Again, the generated display  500  is tailored to the selected developmental stage. 
         [0043]    It is to be understood that the slider  504  is not limited to the three positions shown along slider bar  502  in the figures. The user can position the slider  504  at any, or nearly any, position along a continuum defined by the slider bar  502 . The generated display  500  is modified at each developmental stage so that the generated display  500  changes as the slider  504  is moved by the user. 
         [0044]    In some instances, the developmental stage determination module  208  can determine a developmental stage based on the viewing history of the user. To determine the developmental stage from the viewing history, the developmental stage determination module  208  can access the viewing history of the user from the viewing history database  206  to identify the content previously consumed by the user. Based on the identified content, the developmental stage determination module  208  can then access the metadata tags of the identified content from the content tag database  204 . From the chronological age and relevance included in the content tags, the developmental stage determination module  208  can determine an approximate developmental stage of the user. 
         [0045]    Referring again to  FIG. 2 , the content selection module  210  is configured to select content to present as representations to the user in, for example, the generated display  500 , based on the determined developmental stage of the user. To select the content, the content selection module  210  accesses the metadata tags stored in the content tag database  204 . The chronological ages included in the metadata tags are compared to the developmental stage of the user. Items of Content are selected based on the relevance included in the tag. In some instances, the same item of content can be selected for more than one developmental stage. 
         [0046]    In some embodiments the content selection module  210  can additionally base selection of the content on the viewing history of the user and/or an operating context of the user or client device  108 . The viewing history of the user can, for example, be used to prevent selection of content that has been previously consumed by the user. 
         [0047]    In some embodiments the content selection module  210  can determine or obtain the operating context. One example of determining operating context is useful in distinguishing between two users who share a client device  108  or account to access content. When a device or account is shared between two users, such as between two siblings, determining what type of content is typically viewed at different times of day can be used to later distinguish between the two siblings using the client device  108  or account. For example, a device or account shared between siblings can be habitually accessed by one sibling in the morning (e.g., before school) and by the other sibling in the afternoon (e.g., after school). This viewing history can be used to distinguish between the two sibling users. For example, based on that viewing history and a current time of day included in the operating context, the content selection module  210  can select content appropriate to each user despite the fact that both may use the same client device  108  and even a same account to access content. 
         [0048]    The content representation selection module  212  is configured to select representations of the selected content from a library of pre-generated representations based on the developmental stage. In an embodiment the representations are stored in the content manager  102  (as were content tags in content tags database  204  and viewing history in viewing history database  206 ). The representations form part of the generated display  500  of, for example,  FIGS. 5 ,  6 , and  7 . The representations are targeted to a particular developmental stage or range of developmental stages. The representations each include colors and/or a level of detail that are pre-determined to be appropriate for a particular developmental stage. Further aspects of the representations, such as the presence of text, the size of the representation, or the shape of the representation, are tailored to different possible developmental stages. 
         [0049]    For example, referring again to  FIG. 5 , depicted content representations  506  are tailored to appeal to a user having the developmental stage of a toddler because the slider  504  is positioned along the slider bar  502  adjacent to the depiction of the infant  510 . In this example, the content representations  506  have a relatively low level of detail that is pre-determined to be appropriate for this developmental stage. While not depicted, the representations  506  can be in color rather than black-and-white. The colors for the representations  506  at this developmental stage can be primary, bright, and cheery. Further, the representations  506  are large and widely spaced so that they can be easily selected by a user who has not yet developed fine motor skills. 
         [0050]    As another example, referring again to  FIG. 6 , depicted content representations  606  are tailored to appeal to a user having the developmental stage of an early elementary-aged child because the slider  504  is positioned along the slider bar  502  adjacent to the depiction of the toddler  512 . The content representations  606  have a higher level of detail than those depicted in  FIG. 5 . While not depicted, the content representations  606  can include colors that are predetermined to be appropriate for children of the developmental stage, such as complex, bold, saturated colors. It is to be understood that at least some of the content representations  606  shown in  FIG. 6  can represent the same content as did the content representations  506  of  FIG. 5 . However, the content representations  606  have a greater level of detail and/or are colored using a more complex color palette that is more suitable to the later developmental stage. Moreover, the representations themselves are smaller than those shown in  FIG. 5  as a child of a later developmental stage is likely to have improved fine motor skills needed to view and to select a smaller representation in order to consume the content. 
         [0051]    As a further example, referring again to  FIG. 7 , depicted content representations  706  are tailored to appeal to a user having the developmental stage of an adolescent because the slider  504  is positioned along the slider bar  502  adjacent to the depiction of the adolescent  514 . The content representations  706  have a still higher level of detail than those depicted in both  FIGS. 5 and 6 , reflecting this still later developmental stage. Colors used in the generated display  500  for this developmental stage may be darker and more sophisticated than those of the younger developmental stages. Further, some or all of the content representations  706  are smaller than the representations  506 ,  606  in  FIGS. 5 and 6  because children of this developmental stage have more greater fine motor and cognitive skills. Some of the content representations  706  can include text as children of this developmental stage typically have a higher level of reading and cognitive skills. 
         [0052]    Referring again to  FIG. 2 , a layout module  214  is configured to generate a presentation of the selected representations of the selected content as part of the generated display  500 . The layout module  214  generates the surrounding elements of the generated display  500  such as background graphics and other icons. Other icons can include, for example, a logo identifying the owner/operator of the content manager  102 . The layout module  214  can further determine relative positions and sizes of the content representations. To determine a size of the content representations, which can also be determined by the content representation selection module  212 , the layout module  214  can scale the content representations according to one or more pre-determined rules that dictate the size of the content representations based on the operating context (e.g., type of client device  108 ) and/or the developmental stage of the user. 
         [0053]    For example, referring again to  FIGS. 5 ,  6 , and  7 , the generated display  500  includes the content representations  506 ,  606 ,  706 . The layout module  214  generates the generated display  500  based on the developmental stage indicated by the position of the slider  504  as follows. A background  508  of  FIG. 5  is depicted as being solid white. Further, the layout module  214  can position the content representations closer or further apart based on the developmental stage of the user. The content representations  506 , depicted in  FIG. 5 , are positioned in a more haphazard manner, rather than in rows and columns, about the generated display  500  to appeal to a toddler. Further the corners of the content representations  506  can be rounded by the layout module  214  to appear softer for these users. 
         [0054]    As depicted in  FIG. 6 , because the user&#39;s developmental stage is greater, the background  508  is darkened from white to gray. The content representations  606  are positioned closer together than the content representations  506 . The corners of the content representations  606  are still rounded, like those shown in  FIG. 5 . Unlike  FIG. 5 , the content representations  606  are at least roughly positioned in rows and more content representations  606  are included in the generated display  500 . 
         [0055]    As depicted in  FIG. 7 , because the developmental stage is still greater, the background  508  is darkened from gray to black. The content representations  706  are positioned closer together than the content representations  606 . The corners of the content representations  706  are no longer rounded but are now straight corners. Unlike  FIG. 5 , the content representations  706  are positioned in rows. 
         [0056]    The layout module  214  can further determine whether to include certain functional elements in the generated display. Functional elements can include a developmental stage selection element (e.g., the slider  504 ), a text-based search box, a character bar containing character representations (as described below), and warnings or advisories. As illustrated in  FIG. 7 , for an early teen user, the generated display  500  can include a text search box  704 . Additionally, the content representations  706  are presented according to a more sophisticated layout, with some content representations  706  more prominently displayed by being larger and located at the top of the generated display  500  above the text search box  704  and other content representations  706  less prominently displayed by being smaller and located below the text search box  704 . The relative prominence can be determined based on the viewing history or operating context of the user. 
         [0057]    Referring again to  FIG. 2 , the character bar module  216  is configured to generate the character bar. The character bar is a functional element that can be included in the generated display in some embodiments. The character bar comprises a representations of popular characters (rather than representations of content) that are pre-determined to be appropriate for the developmental stage of the child user. When a displayed character representation is selected by the user, new content for that user&#39;s developmental stage is selected by the content selection module  210  that feature the selected character or that have characters that are related to the selected character. The content representation selection module  212  then selects representations of the newly selected content for inclusion in the generated display. 
         [0058]      FIGS. 8 and 9  depict a generated display  800 ,  900  including a character bar  802 ,  902  for a user at the developmental stages of infant  510  and toddler  512 , respectively. The generated display  800  depicts the addition of the character bar  802  to the generated display  500 . The character bar  802  is generated from characters in the content selected based on the developmental stage as described elsewhere herein. Like the representations of the items of content, the representations of the characters are tailored to the developmental stage of the user. 
         [0059]    Referring now to  FIG. 8 , the character bar  802  includes representations of popular characters  804  in content selected for an infant  510 , as indicated by the position of the slider  504 . The character representations  804 , like the content representations  506 , have a level of detail and/or colors that are pre-determined to be appropriate for the developmental stage of the user. The user can select a character representation  804  by touching it via a touchscreen using a finger or stylus, using a voice command identifying the character represented by the character representation  804 , or by selecting the character representation  804  using a mouse, keyboard, or other known input mechanism. When a character representation  804  within the character bar  802  is selected by the user, content featuring the selected character is selected by the content selection module  210 . The content representation selection module  212  selects content representations  506  of the newly selected content that feature the character or are otherwise related to the selected character (e.g., from the same content producer, from a same set, collection, or series of content, etc.). 
         [0060]    Referring now to  FIG. 9 , the character bar  902  includes character representations  904  of popular characters in content selected for the later developmental stage of the user indicated by the position of the slider  504 . The character representations  904  within the character bar  902  can include some of the same characters as the character bar  802  but are depicted at a higher level of detail more appropriate to the later developmental stage. In this example, some character representations  904  have been removed and other character representations  904  have been added, resulting in the character bar  902 . As depicted and based on the developmental stage of the user, the character representations  904  are also different than the character representations  804  in that the character representations  904  have a defined boundary. As was described in connection with  FIG. 8 , the content representations  606  are generated based on the developmental stage of the user and any selections of a character representation  904  from the character bar  902 . 
         [0061]    In another embodiment, someone responsible for a child user may wish to exercise some control over the content displayed to the child user as well as the content representations shown in the generated displays described herein. Such a person, referred to herein as a “guardian”, can include a parent of the child user or someone who has responsibility for the child user such as a grandparent, legal guardian, teacher, nanny, babysitter, camp counselor, daycare provider, etc. In such an embodiment, the guardian may first be required to authenticate themselves to the system in some fashion known in the art, such as by user name and password, to evidence their authority for exercising such control. 
         [0062]    In one embodiment for a guardian to exercise such control, the generated display includes one or more functional elements for setting an allowable range of developmental stages accessible to the child user. For example, referring now to  FIG. 10 , interface  1000 , which includes the slider bar  502 , the slider  504 , also includes one or more adjustable range limit elements  1002  that can be moved by the guardian using known user interface techniques (e.g., by “clicking and dragging” or “touching and dragging”) to set upper and/or lower limits within the broader range of possible developmental stages defined and depicted by slider bar  502 . Once these range limit elements  1002  are set by the guardian, the child user&#39;s ability to move the slider  504  along the slider bar  502  is limited or constrained to being within the more limited range of possible developmental stages (i.e., between the lower and upper range limit elements  1002 ). In this example, the child user&#39;s ability to indicate their developmental stage has been reduced from being anywhere along the entirety of the slider bar  502 , to instead be limited to being between the lower and upper range limits  1002  shown. Referring again to  FIG. 2 , it is to be understood that the content manager  102  can be configured to provide this range limiting function and, in particular, may do so via the developmental stage determination module  208  or the stage advancement module  218 . 
         [0063]    In another embodiment for a guardian to exercise such control, a child user may already have been exposed to or be developmentally capable of consuming content that is more advanced than the pre-set limit defined by an upper end of a display bar in a generated display. In such a case, the guardian may desire to allow the child user to indicate this greater developmental capability to thereby give the child user access to such more advanced content. 
         [0064]    In this embodiment, the stage advancement module  218  is configured to help the guardian determine whether to allow the child user to be able to advance the developmental stage of the child user beyond the pre-set limit defined and depicted by the upper end of the slider bar  502 . In this embodiment, the stage advancement module  218  causes the content selection module  210  to select content for an advanced developmental stage. The advanced developmental stage is some pre-determined increment above the current upper limit of the slider bar  502 . The stage advancement module  218  then instructs the content representation selection module  212  to generate representations of the selected content for the advanced stage. 
         [0065]    In some instances, the stage advancement module  218  is configured to generate a prompt for display to the authenticated guardian asking that the guardian allow the child to access content tagged to a higher developmental stage, beyond the range of the slider bar  502 . In one example, such a prompt is provided when a child&#39;s viewing history indicates that the child is regularly consuming content near the upper end of the slider bar  502 . The prompt can include the content representations of the more advanced content to thereby give the guardian a better understanding of what content the guardian is making accessible to the child. Receiving a positive response from the guardian causes the various modules of the content manager  102  to advances the pre-defined range of developmental stages thereby allowing the child user to indicate they are of a higher developmental stage and receive a generated display that includes content representations of content of the more advanced developmental stage which then allows the child user to select such more advanced content for consumption. 
         [0066]    Referring now to  FIG. 11  is an example of a generated display  1100  for a guardian to expand a range of developmental stages available or accessible to a child user. The prompt  1102  asks the guardian whether to allow the child to access content of a more advanced developmental stage. To aid the guardian, representations  1106  of content that the guardian is granting the child access to are included and shown in the generated display  1100 . The content representations  1106  can be supplemented with additional information such as parental guidance or other known warnings about the content. In some instances, the content representations  1106  can be altered using one or more visual effects, such as depicting the content representations  1106  in grayscale or black and white instead of color or by depicting the content representations  1106  as greyed out. As has been explained, receiving a positive response from the guardian to the generated response advances the range of developmental stages beyond the pre-defined upper limit, etc. 
         [0067]    Referring now to  FIG. 3  is a flowchart of a method  300  for presenting representations of content, according to some embodiments. The method  300  can be performed by the content manager  102 . The operations of the method  300  can be performed in alternate sequences, as would be apparent to one skilled in the art. 
         [0068]    In an operation  302 , content is tagged with metadata tags indicating an age and, in some embodiments, a relevance of the age to the content. The operation  302  can be performed by the tagging module  202 , as described above. 
         [0069]    In an operation  304 , the viewing history of the user is obtained by, for example, the developmental stage determination module  208  from the viewing history database  206 , as described above. 
         [0070]    In an operation  306 , the operating context is obtained by, for example, the developmental stage determination module  208 , as described above. 
         [0071]    In the operation  308 , the developmental stage of the user is determined. The developmental stage can be determined from the viewing history, the operating context, and/or based on a user input using an input mechanism or functional element. The developmental stage determination module  208  can determine the developmental stage of the user, as described above. 
         [0072]    In an operation  310 , content is selected based on the viewing history, the operating context, and/or the developmental stage of the user. The content selection module  210  can select the content, as described above. 
         [0073]    In an operation  312 , representations of the selected content are generated based on the developmental stage of the user. The representations can be generated by the content representation selection module  212 , as described above. 
         [0074]    In an operation  314 , surrounding layout elements are generated based on the developmental stage of the user. The layout module  214  can generate the surrounding layout elements, as described above. 
         [0075]    In an operation  316 , the representations of the selected content and the surrounding layout elements are used to provide a generated display (e.g., GUI) to the client device  108  by, for example, the layout module  314 , as described above. When a user selects a content representation within the generated display, the content represented by the select content representation is provided for consumption by the user. 
         [0076]    Referring now to  FIG. 4  is a flowchart of a method  400  for expanding a pre-defined range of a developmental stage of a user, according to some embodiments. The method  400  may be performed by the stage advancement module  218 , as described above. 
         [0077]    In an operation  402 , the guardian of the user is authenticated. The guardian is authenticated using authentication processes known to those skilled in the art including, but not limited to, logging into the user account using a username and password. 
         [0078]    In an operation  404 , content of a more advanced developmental stage are selected. The stage advancement module  218  can instruct the content selection module  210  to select the content corresponding to the more advanced developmental stage. 
         [0079]    In an operation  406 , representations of selected content of the more advanced developmental stage are generated. The stage advancement module  218  can instruct the content representation selection module  212  to generate the representations of the content corresponding to the advanced developmental stage. 
         [0080]    In an operation  408 , a prompt or other generated display (e.g., generated display  1100  of  FIG. 11 ) is generated. The prompt includes the content representations generated in the operation  406 . The prompt provides the guardian the option to allow the child user to specify a greater developmental stage thereby resulting in content representations corresponding to the greater developmental stage being shown to the child user in the generated display  500 . 
         [0081]    As described herein, systems and methods to generate a display for presenting representations of content to a user based on a determined developmental stage of the user are provided. The content representations are selected by comparing a developmental stage of the user to content metadata tags that indicate an age of a target user and a relevance to the age. Representations of the selected content and other functional display elements are generated based on the developmental stage of the user. The resulting display changes as the user&#39;s determined developmental stage changes thereby providing a more inviting and cohesive user experience.
