     DESCRIPTION 
     Numerous details are described in order to provide a thorough understanding of the example implementations shown in the drawings. However, the drawings merely show some example aspects of the present disclosure and are therefore not to be considered limiting. Those of ordinary skill in the art will appreciate that other effective aspects and/or variants do not include all of the specific details described herein. Moreover, well-known systems, methods, components, devices, and circuits have not been described in exhaustive detail so as not to obscure more pertinent aspects of the example implementations described herein. 
     Lenticular displays are capable displaying different content at different angles. For example, when viewing a lenticular display from a first angle, a video clip is seen and when viewing the lenticular display from a second angle, a different video clip is seen. 
     In various implementations, a lenticular display includes a matrix of pixels over which a lenticular lens pattern is laid. In various implementations, a first set of the matrix of pixels is visible from a first angle, a second set of the matrix of pixels is visible from a second angle, a third set of pixels is visible from a third angle, and so on. 
     In various implementations described below, this feature of lenticular displays is used to present different content to different users as they move with respect to the lenticular display. For example, in various implementations, a first user and a second user are tracked by an image sensor and first content and second content are displayed to the first user and the second user at whatever angle they are with respect to the lenticular display. 
       FIG.  1    illustrates a first perspective view of an example operating environment at a first time  100 A. The example operating environment at the first time  100 A includes an electronic device  101  having an image sensor  112  and a lenticular display  110 . The example operating environment at the first time  100 A includes a first user  120 A and a second user  120 B of different heights viewing the lenticular display. At the first time, the first user  120 A is at a first location and the second user  120 B is at a second location. 
     Although  FIG.  1    illustrates only two users in the example operating environment, in various implementations, any number of users may be present in the example operating environment and have different content presented thereto. 
       FIG.  2    illustrates a second perspective view of the example operating environment at the first time  100 A. The second perspective view is illustrated from a position behind the first user  120 A looking towards the device  101 . From this angle, first content  130 A can be seen on the lenticular display  110 . The first content  130 A includes a cylinder  140  viewed from particular vertical angle. At the particular vertical angle, the top  141  of the cylinder  140  can be seen. 
       FIG.  3    illustrates a third perspective view of the example operating environment at the first time  110 A. The third perspective view is illustrated from a position behind the second user  120 B looking towards the device  101 . From this angle, second content  130 B can be seen on the lenticular display  110 . The second content  130 B includes the same cylinder  140  viewed from a different vertical angle. At the different vertical angle, the top  141  of the cylinder  140  cannot be seen. However, at the different vertical angle, the bottom  142  of the cylinder  140  can be seen. 
     In various implementations, the first content  130 A and the second content  130 B are two different images. In various implementations, the first content  130 A and the second content  130 B are two different videos. In various implementations, the first content  130 A and the second content  130 B are different versions of the same underlying content. For example, the second content  130 B may be a censored version of the first content  130 A. 
     In various implementations, the first content  130 A and/or second content  130 B is based on metadata regarding the user viewing the content. For example, if the first user  120 A is associated with metadata indicating that the first user  120 A has permission to view certain content, but that second user  120 B is not associated with metadata indicating that the second user  120 B has permission to view the certain content, the first content  130 A may include that certain content whereas the second content  130 A may not include that certain content, but rather, other content. For example, the first user  120 A may be associated with metadata indicating that the first user  120 A has permission to watch television shows rated TV-MA or less, whereas the second user  120 B is associated with metadata indicating that the second user  120 B has permission to watch television shows rated TV-PG or less. Thus, the first content  130 A may include a TV-MA rated television show and the second content may include a different show (rated TV-PG or less) or a censored version of the TV-MA rated television show. 
     In various implementations, as in  FIGS.  2  and  3   , the first content  130 A and the second content  130 A are different perspective views of the same object or scene. In various implementations, the object is a virtual object. In various implementations, the object is a three-dimensional object. In various implementations, the scene is a virtual scene. In various implementations, the scene is a three-dimensional scene. 
       FIG.  4    illustrates a top view of the example operating environment at the first time  100 A. The device  101  determines a first horizontal angle (θ 1 ) of the first user  120 A with respect to a line  115  perpendicular to the lenticular display  110  and a second horizontal angle (θ 2 ) of the second user  120 B with respect to the line  115  perpendicular to the lenticular display  110 . In  FIG.  4   , the first horizontal angle (θ 1 ) is approximately −30 degrees and the second horizontal angle (θ 2 ) is approximately 45 degrees. 
     In various implementations, the device  101  determines the first horizontal angle (θ 1 ) and the second horizontal angle (θ 2 ) using the image sensor  112  to capture an image of the first user  120 A and the second user  120 B and detecting the first user  120 A and the second user  120 B in the captured image. The device  101  controls the lenticular display  110  to display the first content  130 A at the first horizontal angle (θ 1 ) (e.g., to the first user  120 A) and the second content  130 B at the second horizontal angle (θ 2 ) (e.g., to the second user  120 B). 
       FIG.  5    illustrates a top view of the example operating environment at a second time  100 B. At the second time, the first user  120 A has moved from the first position to a third position and the second user  120 B has moved from the second position to a fourth position. The device  101  determines a third horizontal angle (θ 3 ) of the first user  120 A with respect to the line  115  perpendicular to the lenticular display  110  and a fourth horizontal angle (θ 4 ) of the second user  120 B with respect to the line  115  perpendicular to the lenticular display  110 . In  FIG.  5   , the third horizontal angle (θ 3 ) is approximately −60 degrees and the fourth horizontal angle (θ 4 ) is approximately −30 degrees. 
     The device  101  controls the lenticular display  110  to display the first content  130 A at the third horizontal angle (θ 3 ) (e.g., to the first user  120 A) and the second content  130 B at the fourth horizontal angle (θ 4 ) (e.g., to the second user  120 B). Thus, even though the first horizontal angle (θ 1 ) and the fourth horizontal angle (θ 4 ) are, coincidentally, the same, different content is displayed at that angle at the first time (e.g., the first content  130 A to the first user  120 A) and the second time (e.g., the second content  130 B to the second user  120 B). 
       FIG.  6    illustrates a top view of the example operating environment at a third time  100 C. At the third time, the first user  120 A remains at the third position and the second user  120 B remains at the fourth position. However, the device  101  has moved (e.g., rotated), changing the horizontal angles of the users with respect to the line  115  perpendicular to the lenticular display  110 . 
     The device  101  determines a fifth horizontal angle (θ 5 ) of the first user  120 A with respect to the line  115  perpendicular to the lenticular display  110  and a sixth horizontal angle (θ 6 ) of the second user  120 B with respect to the line  115  perpendicular to the lenticular display  110 . In various implementations, the device  101  determines the fifth horizontal angle (θ 5 ) and the sixth horizontal angle (θ 6 ) based on data from a pose estimation unit of the device  101 , such as an inertial measurement unit (IMU), IR encoder, or potentiometer. In  FIG.  6   , the third horizontal angle (θ 3 ) is approximately −45 degrees and the fourth horizontal angle (θ 4 ) is approximately −15 degrees. The device  101  controls the lenticular display  110  to display the first content  130 A at the fifth horizontal angle (θ 5 ) (e.g., to the first user  120 A) and the second content  130 B at the sixth horizontal angle (θ 6 ) (e.g., to the second user  120 B). 
       FIG.  7    illustrates a top view of the example operating environment at the third time  100 C in which each eye of each user is presented different content. At the third time, the first user  120 A remains at the third position, the second user  120 B remains at the fourth position, and the device  101  has been moved. 
     The device  101  determines the fifth horizontal angle (θ 5 ) of a first eye of the first user  120 A with respect to the line  115  perpendicular to the lenticular display  110 , the sixth horizontal angle (θ 6 ) of a first eye of the second user  120 B with respect to the line  115  perpendicular to the lenticular display  110 , a seventh angle (θ 7 ) of a second eye of the first user  120 A with respect to the line  115  perpendicular to the lenticular display  110 , and an eighth angle (θ 8 ) of a second eye of the second user  120 B with respect to the line  115  perpendicular to the lenticular display  110 . 
     The device  101  controls the lenticular display  110  to display the first content  130 A at the fifth horizontal angle (θ 5 ) (e.g., to the first eye of the first user  120 A) and the second content  130 B at the sixth horizontal angle (θ 6 ) (e.g., to the first eye of the second user  120 B). The device  101  further controls the lenticular display  110  to display third content at the seventh horizontal angle (θ 7 ) (e.g., to the second eye of the first user  120 A) and fourth content at the eighth horizontal angle (θ 8 ) (e.g., to the second eye of the second user  120 B). 
     In various implementations, the first content  130 A and the third content are different perspectives of the same object or scene. Similarly, in various implementations, the second content  130 B and the fourth content are different perspectives of the same object or scene. 
       FIG.  8    illustrates a side view of the example operating environment at the third time  100 C. The device  101  determines a first vertical angle (φ 1 ) of the first user  120 A with respect to the line  115  perpendicular to the lenticular display  110  and a second vertical angle (φ 2 ) of the second user  120 B with respect to the line  115  perpendicular to lenticular display  110 . The device  101  controls the lenticular display  110  to display the first content  130 A at the fifth horizontal angle (θ 5 ) (e.g., to the first user  120 A) based on the first vertical angle (φ 1 ) and the second content  130 B at the sixth horizontal angle (θ 6 ) (e.g., to the second user  120 B) based on the second vertical angle (φ 2 ). 
     As a particular example, in various implementations, the first content  130 A includes a virtual three-dimensional object (e.g., a cylinder) displayed from a first horizontal perspective based on the fifth horizontal angle (θ 5 ) and a first vertical perspective based on the first vertical angle (φ 1 ), the third content includes the same virtual object displayed from a second horizontal perspective based on the seventh horizontal angle (θ 7 ) and the first vertical perspective based on the first vertical angle (φ 1 ), the second content  130 B includes the same virtual object displayed from a third horizontal perspective based on the sixth horizontal angle (θ 6 ) and a second vertical perspective based on the second vertical angle (φ 2 ), and the fourth content includes the same virtual object displayed from a fourth horizontal perspective based on the eighth horizontal angle (θ 8 ) and the second vertical perspective based on the second vertical angle (φ 2 ). Thus, each user stereoscopically views a virtual three-dimensional object with the correct vertical perspective for that user. 
       FIG.  9    is a flowchart representation of a method  900  of operating a lenticular display in accordance with some implementations. In various implementations, the method  900  is performed by a device with one or more processors, non-transitory memory, an image sensor, and a lenticular display (e.g., the device  101  of  FIG.  1   ). In some implementations, the method  900  is performed by processing logic, including hardware, firmware, software, or a combination thereof. In some implementations, the method  900  is performed by a processor executing instructions (e.g., code) stored in a non-transitory computer-readable medium (e.g., a memory). 
     The method  900  begins, in block  910 , with the device capturing, using the image sensor, a first image. 
     The method  900  continues, in block  920 , with the device determining, from the first image, a first horizontal angle of a first user at a first time with respect to a line perpendicular to the lenticular display and a first horizontal angle of a second user at the first time with respect to the line perpendicular to the lenticular display. In various implementations, the first time is when the first image is captured. For example, in  FIG.  4   , the device (based on an image captured using the image sensor  112 ) determines the first horizontal angle (θ 1 ) and the second horizontal angle (θ 2 ). In various implementations, the device  101  employs a face detection algorithm on the first image to determine locations in the image of the first user and the second user. The locations in the image are mapped to horizontal (and, in various implementations, vertical) angles with respect to the line perpendicular to the lenticular display. 
     The method  900  continues, in block  930 , with the device displaying, via the lenticular display, first content at the first horizontal angle of the first user and second content, different than the first content, at the first horizontal angle of the second user. 
     In various implementations, the first content includes a first image and the second content includes a second image different than the first image. In various implementations, the first content includes a first video and the second content includes a second video different than the first video. 
     In various implementations, the first content includes a first version of content and the second content includes a second version of the content different from the first version of the content. For example, in various implementations, the second version of the content is a censored version of the first version of the content. 
     In various implementations, displaying the first content at the first horizontal angle of the first user includes displaying an object or scene at a first perspective and displaying the second content at the first horizontal angle of the second user includes displaying the object or scene at a second perspective different than the first perspective. For example, in  FIGS.  2  and  3   , the device  101  displays, for the first user  120 A, a cylinder  140  from a first vertical perspective at which the top  141  is visible and displays, for the second user  120 B, the cylinder  140  from a second vertical perspective at which the top  141  is not visible, but at which the bottom  142  is visible. 
     In various implementations, the method  900  further includes determining, based on the first image, an identity of the first user and an identity of the second user, wherein the first content is based on the identity of the first user and the second content is based on the identity of the second user. For example, in various implementations, the first user is associated with a first subscription video service account and the second user is associated with a second subscription video service account and a respective “next episode” is displayed to each user. In various implementations, the method  900  further includes determining, from the first image, a first vertical angle of the first user at the first time with respect to the line perpendicular to the lenticular display and a first vertical angle of the second user at the first time with respect to the line perpendicular to the lenticular display. For example, in  FIG.  8   , the device  101  determines the first vertical angle (φ 1 ) of the first user and the second vertical angle (φ 2 ) of the second user. In various implementations, wherein displaying the first content at the first horizontal angle of the first user and the second content at the first horizontal angle of the second user is based on the first vertical angle of the first user and the first vertical angle of the second user. For example, in  FIGS.  2  and  3   , the device  101  displays, for the first user  120 A, a cylinder  140  from a first vertical perspective at which the top  141  is visible and displays, for the second user  120 B, the cylinder  140  from a second vertical perspective at which the top  141  is not visible, but at which the bottom  142  is visible. Accordingly, in various implementations, displaying the first content at the first horizontal angle of the first user includes displaying an object or scene at a first vertical perspective based on the first vertical angle and displaying the second content at the first horizontal angle of the second user includes displaying the object or scene at a second vertical perspective based on the second vertical angle. 
     In various implementations, the first content and the second content are displayed at the same vertical perspective based on the first vertical angle and the second vertical angle. For example, in various implementations, a virtual object is displayed at a vertical perspective based on the average of the first vertical angle and the second vertical angle. 
     The method  900  continues, at block  940 , with the device determining a second horizontal angle of the first user at a second time, different than the first time, with respect to the line perpendicular to the lenticular display and a second horizontal angle of the second user at the second time with respect to the line perpendicular to the lenticular display. For example, whereas in  FIG.  4   , the device  101  determines the first horizontal angle (θ 1 ) of the first user  120 A at the first time and the second horizontal angle (θ 2 ) of the second user  120 B at the first time, in  FIG.  5   , the device  101  determines the third horizontal angle (θ 3 ) of the first user  120 A at the second time and the fourth horizontal angle (θ 4 ) of the second user  120 B at the second time. 
     In various implementations, the second horizontal angle of the first user is different than the first horizontal angle of the first user. For example, in  FIGS.  4  and  5   , the third horizontal angle (θ 3 ) is different than the first horizontal angle (θ 1 ). In various implementations, the second horizontal angle of the second user is the same as the first horizontal angle of the first user. For example, in  FIGS.  4  and  5   , the fourth horizontal angle (θ 4 ) is the same as the first horizontal angle (θ 1 ). 
     In various implementations, the method  900  includes capturing, using the image sensor, a second image, wherein determining the second horizontal angle of the first user and the second horizontal angle of the second user is based on the second image. In various implementations, the method  900  includes receiving data from a pose estimation unit (IMU), wherein determining the second horizontal angle of the first user and the second horizontal angle of the second user is based on the data from the pose estimation unit. 
     The method  900  continues, in block  950 , with the device displaying, via the lenticular display, the first content at the second horizontal angle of the first user and the second content at the second horizontal angle of the second user. 
     In various implementations, the method  900  further includes determining a third horizontal angle of the first user at the first time with respect to the line perpendicular to the lenticular display and a third horizontal angle of the second user at the first time with respect to the line perpendicular to the lenticular display. For example, in  FIG.  7   , the device  101  determines the seventh horizontal angle (θ 7 ) of the first user  120 A and the eighth horizontal angle (θ 8 ) of the second user  120 B. The method  900  further includes displaying, via the lenticular display, third content at the third horizontal angle of the first user and fourth content, different than the third content, at the third horizontal angle of the second user. 
     In various implementations, displaying the first content at the first horizontal angle of the first user includes displaying an object or scene at a first horizontal perspective based on the first horizontal angle of the first user and displaying the third content at the third horizontal angle of the first user includes displaying the object or scene at second horizontal perspective based on the third horizontal angle of the first user. 
       FIG.  10    is a block diagram of an example of the device  101  of  FIG.  1    in accordance with some implementations. While certain specific features are illustrated, those skilled in the art will appreciate from the present disclosure that various other features have not been illustrated for the sake of brevity, and so as not to obscure more pertinent aspects of the implementations disclosed herein. To that end, as a non-limiting example, in some implementations the device  101  includes one or more processing units  1002  (e.g., microprocessors, ASICs, FPGAs, GPUs, CPUs, processing cores, and/or the like), one or more input/output (I/O) devices and sensors  1006 , one or more communication interfaces  1008  (e.g., USB, FIREWIRE, THUNDERBOLT, IEEE 802.3x, IEEE 802.11x, IEEE 802.16x, GSM, CDMA, TDMA, GPS, IR, BLUETOOTH, ZIGBEE, and/or the like type interface), one or more programming (e.g., I/O) interfaces  1010 , a lenticular display  1012 , an image sensor  1014 , a memory  1020 , and one or more communication buses  1004  for interconnecting these and various other components.

     The memory  1020  includes high-speed random-access memory, such as DRAM, SRAM, DDR RAM, or other random-access solid-state memory devices. In some implementations, the memory  1020  includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid-state storage devices. The memory  1020  optionally includes one or more storage devices remotely located from the one or more processing units  1002 . The memory  1020  comprises a non-transitory computer readable storage medium. In some implementations, the memory  1020  or the non-transitory computer readable storage medium of the memory  1020  stores the following programs, modules and data structures, or a subset thereof including an optional operating system  1030  and a content presentation module  1040 . 
     The operating system  1030  includes procedures for handling various basic system services and for performing hardware dependent tasks. In some implementations, the content presentation module  1040  is configured to present different content to different users at different angles via the lenticular display  1012 . To that end, in various implementations, the content presentation module  1040  includes a user detection unit  1042  and a content presenting unit  1044 . 
     In some implementations, the user detection unit  1042  is configured to determine a first horizontal angle of a first user with respect to a line perpendicular to the lenticular display  1012  and a second horizontal angle of a second user with respect to the line perpendicular to the lenticular display  1012 . To that end, in various implementations, the user detection unit  1042  includes instructions and/or logic therefor, and heuristics and metadata therefor. 
     In some implementations, the content presenting unit  1044  is configured to display, via the lenticular display, first content at the first horizontal angle of the first user and second content, different than the first content, at the first horizontal angle of the second user. To that end, in various implementations, the content presenting unit  1044  includes instructions and/or logic therefor, and heuristics and metadata therefor. 
     Although the user detection unit  1042  and the content presenting unit  1044  are shown as residing on a single device (e.g., the device  101  of  FIG.  1   ), it should be understood that in other implementations, the user detection unit  1042  and the content presenting unit  1044  may be located in separate computing devices. 
     Moreover,  FIG.  10    is intended more as a functional description of the various features that could be present in a particular implementation as opposed to a structural schematic of the implementations described herein. As recognized by those of ordinary skill in the art, items shown separately could be combined and some items could be separated. For example, some functional modules shown separately in  FIG.  10    could be implemented in a single module and the various functions of single functional blocks could be implemented by one or more functional blocks in various implementations. The actual number of modules and the division of particular functions and how features are allocated among them will vary from one implementation to another and, in some implementations, depends in part on the particular combination of hardware, software, and/or firmware chosen for a particular implementation. 
     While various aspects of implementations within the scope of the appended claims are described above, it should be apparent that the various features of implementations described above may be embodied in a wide variety of forms and that any specific structure and/or function described above is merely illustrative. Based on the present disclosure one skilled in the art should appreciate that an aspect described herein may be implemented independently of any other aspects and that two or more of these aspects may be combined in various ways. For example, an apparatus may be implemented and/or a method may be practiced using any number of the aspects set forth herein. In addition, such an apparatus may be implemented and/or such a method may be practiced using other structure and/or functionality in addition to or other than one or more of the aspects set forth herein. 
     It will also be understood that, although the terms “first,” “second,” etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first node could be termed a second node, and, similarly, a second node could be termed a first node, which changing the meaning of the description, so long as all occurrences of the “first node” are renamed consistently and all occurrences of the “second node” are renamed consistently. The first node and the second node are both nodes, but they are not the same node. 
     The terminology used herein is for the purpose of describing particular implementations only and is not intended to be limiting of the claims. As used in the description of the implementations and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
     As used herein, the term “if” may be construed to mean “when” or “upon” or “in response to determining” or “in accordance with a determination” or “in response to detecting,” that a stated condition precedent is true, depending on the context. Similarly, the phrase “if it is determined [that a stated condition precedent is true]” or “if [a stated condition precedent is true]” or “when [a stated condition precedent is true]” may be construed to mean “upon determining” or “in response to determining” or “in accordance with a determination” or “upon detecting” or “in response to detecting” that the stated condition precedent is true, depending on the context.
