Description:
PRIORITY INFORMATION 
     This application is a Continuation of U.S. application Ser. No. 17/083,835 filed on Oct. 29, 2020, the contents of which are incorporated herein by reference. 
    
    
     TECHNICAL FIELD 
     The present disclosure relates generally to a computing device, and more particularly, to methods, apparatuses, and systems related to augmented reality (AR). 
     BACKGROUND 
     A computing device can be, for example, a personal laptop computer, a desktop computer, a smart phone, a tablet, a wrist-worn device, a digital camera, and/or redundant combinations thereof, among other types of computing devices. In some examples, a computing device can display an augmented reality (AR) and/or perform artificial intelligence (AI) operations. 
     AR can overlay virtual objects on a real-world (e.g., natural) environment. For example, AR can add a  3 D hologram to reality. In some examples, AR can be an interactive experience of a real-world environment where real-world objects are enhanced by computer-generated perceptual information. The AR can mask a portion of the real-world environment and/or add to the real-world environment such that it is perceived as an immersive aspect of the real-world environment. Accordingly, AR can alter a person&#39;s perception of a real-world environment. A head-up display, a headset, a smart glass, smart contacts, a light field display, a laser, and/or several sources of light can be used to create AR. 
     In some examples, a computing device can include an AI accelerator. An AI accelerator can include components configured to enable the computing device to perform AI operations. In some examples, AI operations may include machine learning or neural network operations, which may include training operations or inference operations, or both.

     DETAILED DESCRIPTION 
     The present disclosure includes methods, apparatuses, and systems related to displaying an AR responsive to an input. An example method can include receiving an input at an AR platform of a computing device from a processing resource of the computing device, receiving an image at the AR platform from a camera of the computing device, comparing the image to a number of AR images included on the AR platform, determining at the AR platform that the image is an AR image of the number of AR images, receiving at a user interface an AR associated with the AR image from the AR platform, and displaying the AR on the user interface in response to receiving the AR. 
     An input can include, but is not limited to, a timestamp, weather data, event data, a rating, a user preference, a user input, or a location. The location can be, for example, a location of the computing device. The location of the computing device can be determined using an accelerometer, a gyroscope, a global positioning system (GPS), a wi-fi network being used by the computing device, or a post on social media. 
     An AR can be received and/or displayed responsive to the location of the computing device. For example, an AR can be received at a user interface and/or displayed on the user interface of a computing device when the location of the computing device is within a particular distance of the AR image, when the location of the computing device is within a particular area of an event, when the location of the computing device is a particular distance away from a different location and/or, when the computing device is within a particular distance of a different location. 
     In a number of embodiments, a user can be notified that AR is available prior to displaying the AR. For example, a notification can be displayed on the user interface to notify the user that AR is available. A notification can be displayed responsive to receiving an input and/or determining the image generated by the camera is an AR image of the number of AR images on the AR platform. 
     A user can choose to ignore or view the AR. The notification can be removed from the user interface and the AR can be displayed on the user interface responsive to receiving a selection on the user interface. In some examples, the notification can be removed from the user interface responsive to receiving a different selection on the user interface or a user ignoring the notification. For example, the notification can be removed from the user interface after a particular period of time has passed without the user interface receiving a selection. 
     The notification can include AR data. The AR data can be from the AR platform on the computing device. The AR platform can include a number of AR images and AR data associated with each of the number of AR images. The AR data can include the creator, genre, content, and/or ratings of the AR, for example. In some examples, the AR data can include data for displaying an AR. The AR data or a portion of the AR data can be stored on the AR platform and/or in memory on and/or external to the computing device. 
     A user&#39;s response to the notification can be stored as user data. The user data can be stored in memory on and/or external to the computing device. The AR data and/or the user data can be used to perform AI operations on an AI model. AI operations can, for example, set (e.g., create) user preferences. The user preferences can be set based on a user&#39;s previous responses to notifications and/or a user&#39;s previous responses to AR. In some examples, the computing device may not notify a user if an AR is available responsive to AR data including one or more characteristics in common with characteristics of an AR a user has ignored before. For example, the computing device may not notify a user if an AR is available responsive to the AR being of a particular genre that the user has previously ignored. 
     As used herein, “a number of” something can refer to one or more of such things. For example, a number of computing devices can refer to one or more computing devices. A “plurality” of something intends two or more. 
     The figures herein follow a numbering convention in which the first digit or digits correspond to the drawing figure number and the remaining digits identify an element or component in the drawing. Similar elements or components between different figures may be identified by the use of similar digits. For example, reference numeral  102  may reference element “ 2 ” in  FIG.  1   , and a similar element may be referenced as  202  in  FIG.  2   . As will be appreciated, elements shown in the various embodiments herein can be added, exchanged, and/or eliminated so as to provide a number of additional embodiments of the present disclosure. In addition, the proportion and the relative scale of the elements provided in the figures are intended to illustrate various embodiments of the present disclosure and are not to be used in a limiting sense. 
       FIG.  1    illustrates an example of a user interface  102  of a computing device  100  for displaying an AR in accordance with a number of embodiments of the present disclosure. The user interface  102 , as illustrated in  FIG.  1   , can further include an AR image  104 . An AR image  104  can be an image that triggers an AR. 
     In a number of embodiments, a camera (e.g., camera  428  in  FIG.  4   , camera  528  in  FIG.  5   ) can detect an AR image  104  by comparing an image generated by the camera to a number of AR images and determining the image generated by the camera is an AR image of the number of AR images. In some examples, computing device  100  can include one or more cameras. One of the one or more cameras can be used solely for detecting AR images. In a number of embodiments, one or more optical sensors can be used with one or more cameras to detect an AR image  104  or, in contrast, one or more optical sensors can be used instead of one or more cameras to detect an AR image  104 . 
     AR can overlay virtual objects on a real-world environment to mask a portion of the real-world environment and/or add to the real-world environment such that it is perceived as an immersive aspect of the real-world environment. In some examples, AR can display and/or automate a number of images and/or enhance the AR image  104  to move and/or change on the user interface  102 , as shown in  FIG.  2   . 
     The user interface  102  can be generated by the computing device  100 . The user interface  102  can be a graphical user interface (GUI) that can provide and/or receive information to and/or from the user of the computing device  100 . The user interface  102  can be shown on a display of the computing device  100 . In some examples, the display can be a touchscreen. 
       FIG.  2    illustrates an example of a user interface  202  of a computing device  200  for displaying an AR in accordance with a number of embodiments of the present disclosure. In a number of embodiments, the user interface  202  can be generated in response to determining an image generated by a camera is an AR image (e.g., AR image  104  in  FIG.  1   ). The user interface  202 , as illustrated in  FIG.  2   , can include a notification  206 . 
     The user interface  202  can notify a user that an AR is available by displaying the notification  206 . However, embodiments are not limited to displaying a notification  206  on a user interface  202 . A computing device  200  can notify a user that an AR is available by producing audio and/or vibration, for example. The notification  206  can be displayed, audio can be produced, and/or vibration can be produced by the computing device  200  responsive to receiving an input and/or determining an image generated by a camera is an AR image. 
     In some examples, the user interface  202  can display the AR responsive to receiving a command and/or a selection of the notification  206  on the user interface  202 . A command and/or a selection can be a user pressing, tapping, and/or clicking on the notification  206  displayed on the user interface  202 . In a number of embodiments, the user interface  202  can display the AR responsive to the computing device receiving a passcode and/or password, the computing device  200  performing facial recognition on the user, and/or the computing device  200  performing fingerprint identification on the user. 
     A user can choose to ignore or view the AR content. The notification  206  can be removed from the user interface  202  and the AR can be displayed on the user interface  202  responsive to receiving a command and/or a selection to view the AR on the user interface  202 . In some examples, the notification  206  can be removed from the user interface  202  responsive to the user interface  202  receiving a command and/or a selection from the user to ignore (e.g., not view) the AR or a user ignoring the notification  206 . For example, the notification  206  can be removed from the user interface  202  after a particular period of time has passed without the user interface  202  receiving a command and/or a selection. 
     The notification  206  can include AR data. In some examples, the AR data can be displayed on the user interface  202  responsive to the user interface  202  receiving a selection from the user to view the AR data. The AR data can be metadata received from the AR image. The AR data can include the creator, genre, content, and/or ratings, for example. The notification  206 , AR data, and/or a portion of the AR data can be stored in memory on and/or external to the computing device  200 . 
     A user&#39;s response to the notification  206  can be stored as user data. The user data can be stored in memory on and/or external to the computing device  200 . The AR data and/or the user data can be used to perform AI operations. AI operations can, for example, set (e.g., create) user preferences. The user preferences can be set based on a user&#39;s previous responses to notifications and/or a user&#39;s previous responses to AR. In some examples, the computing device  200  may not notify a user if an AR is available responsive to AR data including one or more characteristics in common with characteristics of an AR a user has previously ignored. For example, the computing device  200  may not notify a user if an AR is available responsive to the AR having a particular rating that the user has ignored before. 
       FIG.  3    illustrates an example of a user interface  302  of a computing device  300  for displaying an AR  308  in accordance with a number of embodiments of the present disclosure. In some examples, the user interface  302  can be generated in response to receiving an input at the computing device  300  and determining an image generated by a camera is an AR image (e.g., AR image  104  in  FIG.  1   ). 
     The input can be generated by the computing device  300  or generated by a different computing device and received at the computing device  300 . The input can be, but is not limited to a location, a timestamp, weather data, event data, ratings, user preferences, and/or a user input. 
     The location can be, for example, a location of the computing device  300 . The location of the computing device  300  can be determined using an accelerometer, a gyroscope, a global positioning system (GPS), a wi-fi network, or a social media application. An AR  308  can be received at the user interface  302  and/or displayed on the user interface  302  responsive to a location of the computing device  300 . For example, an AR  308  can be received and/or displayed when the location of the computing device  300  is within a particular distance of the AR image, when the location of the computing device  300  is within a particular area of an event, when the location of the computing device  300  is a particular distance away from a different location, and/or when the location of the computing device  300  is within a particular distance of a different location. The data representing the location of the computing device  300  can be compared to the data representing the different location, for example. 
     A timestamp can identify a date and/or time of day. The timestamp can be generated by a clock on the computing device  300 . In some examples, a timestamp can be received at the computing device  300  from a different device. An AR  308  can be displayed responsive to a timestamp. For example, an AR  308  can be displayed when the timestamp is at a particular time and/or within a particular time range. 
     Weather data can include temperature data, cloud cover data, precipitation data, and/or storm data, for example. The weather data can be generated using sensors on the computing device  300  and/or external to the computing device  300 . In some examples, the weather data can be received at the computing device  300  from a different device. An AR  308  can be displayed responsive to weather data. For example, an AR  308  can be displayed when a temperature at the computing device&#39;s  300  current location is within a particular temperature range, when cloud coverage at the computing device&#39;s  300  current location is within a particular cloud coverage range, when precipitation at the computing device&#39;s  300  current location is within a particular precipitation range, and/or when there is a storm at the computing device&#39;s  300  current location. 
     Event data can be, for example, sporting events, conventions, tours, landmarks, and/or other attractions. Event data can be stored in memory on the computing device  300  and/or external to the computing device  300 . Event data can be derived from a user&#39;s calendar, email, and/or social media, for example. In some examples, event data can be received at the computing device  300  from a different device. An AR  308  can be displayed when the computing device  300  is within a particular area where the event is occurring and/or an AR  308  can be displayed during a time period the event is scheduled for. 
     Ratings can include review data, popularity data, and/or age data (e.g., appropriate ages for viewing content). The ratings can be generated by a user, other viewers, and/or organizations. The ratings can be received at the computing device  300 . The computing device  300  can compare the ratings with the user&#39;s data and/or preferences. For example, an AR  308  can be displayed responsive to the age data of the AR being appropriate for the user&#39;s age. 
     User preferences can include notifying a user that an AR  308  is available if the AR image is from a particular creator, of a particular genre, includes particular content, and/or has a particular rating. User preferences can be manually inputted by a user and/or learned over time using AI. AI operations using an AI model can be performed to determine whether to notify a user of the availability of an AR  308  and/or whether to display an AR  308 . User data including one or more user preferences and/or AR data can be used as weights in the AI operation. In some examples, the user data can include one or more of a user&#39;s previous responses to AR  308 . 
     In a number of embodiments, the user can set a particular AR creator as a trusted creator. An AR creator, as used herein, can be a person, organization, and/or company that creates, distributes and/or owns the AR  308 . Setting the particular AR creator as a trusted creator can allow the computing device  300  to notify the user when an AR  308  from that AR creator is available. In some examples, the computing device  300  performing AI operations using user data and/or AR data can set a particular creator as a trusted AR creator. The computing device can determine an AR image is from a trusted creator by comparing a creator of the AR image with a number of trusted creators. If the creator of the AR image matches one of the number of trusted creators the AR image is from a trusted creator. 
       FIG.  4    illustrates an example of a computing device (e.g., apparatus)  400  used for displaying an AR in accordance with a number of embodiments of the present disclosure. The computing device  400  can be an apparatus. As illustrated in  FIG.  4   , computing device  400  can include a processing resource (e.g., processor)  422 , a memory  424 , a user interface  402 , a camera  428 , and an AR platform  429 . The computing device  400  can be, for example, a personal laptop computer, a desktop computer, a smart phone, a tablet, a wrist-worn device, a digital camera, and/or redundant combinations thereof, among other types of computing devices. 
     The memory  424  can be any type of storage medium that can be accessed by the processing resource  422  to perform various examples of the present disclosure. For example, the memory  424  can be a non-transitory computer readable medium having computer readable instructions (e.g., computer program instructions) stored thereon that are executable by the processing resource  422  to receive first signaling including data representing at least one of: a timestamp, weather, an event, a rating, a user preference, a user input, or a location of a computing device at an AR platform  429  of the computing device  400  from the processing resource  422 , receive second signaling including data representing an image at the AR platform  429  from a camera  428  of the computing device  400 , compare the data representing the image to data representing a number of AR images included on the AR platform  429 , determining at the AR platform  429  that the image is an AR image of the number of AR images in response to a particular portion of the data representing the image matching data representing the AR image, receive at a user interface  402  of the computing device  400  third signaling including data representing an AR associated with the AR image from the AR platform  429  in response to receiving the first signaling and determining the image is the AR image, and display the data representing the AR associated with the AR image on the user interface  402  of the computing device  400  in response to receiving the third signaling. As used herein, signaling can include a communication (e.g., a radio signal) that carries data from one location to another. In some embodiments, the computing device  400  can include communication devices, such as, but not limited to, radios. 
     The memory  424  can be volatile or nonvolatile memory. The memory  424  can also be removable (e.g., portable) memory, or non-removable (e.g., internal) memory. For example, the memory  424  can be random access memory (RAM) (e.g., dynamic random access memory (DRAM) and/or phase change random access memory (PCRAM)), read-only memory (ROM) (e.g., electrically erasable programmable read-only memory (EEPROM) and/or compact-disc read-only memory (CD-ROM)), flash memory, a laser disc, a digital versatile disc (DVD) or other optical storage, and/or a magnetic medium such as magnetic cassettes, tapes, or disks, among other types of memory. 
     Further, although memory  424  is illustrated as being located within computing device  400 , embodiments of the present disclosure are not so limited. For example, memory  424  can be located on an external computing resource (e.g., enabling computer readable instructions to be downloaded over the Internet or another wired or wireless connection). 
     The AR platform  429  can be included in an operating system (OS) of the computing device  400  and/or included in an application downloaded onto the computing device  400 . A number of AR images and AR data associated with each of the number of AR images can be included on the AR platform  429 . The AR platform  429  can be updated with new data periodically or in response to a user command. New AR images with their associated AR data can be added to the AR platform  429  and/or existing AR images with their associated AR data can be updated on the AR platform  429 . For example, AR data associated with an existing AR image can be updated to display a new AR. 
     As illustrated in  FIG.  4   , computing device  400  includes a user interface  402 . A user (e.g., operator) of computing device  400 , can interact with computing device  400  via user interface  402  shown on a display. For example, the user interface  402  via a display can provide (e.g., display and/or present) information to the user of computing device  400 , and/or receive information from (e.g., input by) the user of computing device  400 . For instance, in some embodiments, the user interface  402  can be a GUI that can provide and/or receive information to and/or from the user of computing device  400 . The display showing the user interface  402  can be, for instance, a touchscreen (e.g., the GUI can include touchscreen capabilities). 
     The computing device  400  can include one or more cameras  428 . The one or more cameras  428  can be used to detect an AR image. In some examples, one of the one or more cameras  428  can be used solely for detecting an AR image. In a number of embodiments, one or more optical sensors, not illustrated in  FIG.  4   , can be used with the one or more cameras or instead of the one or more cameras to detect an AR image. 
     In some examples, the computing device  400  can be a mobile device of a user. The user can be walking with their mobile device through an art gallery looking at various pieces of art. Each piece of art can include a corresponding AR image on and/or near it. A camera on the mobile device can detect one or more of the AR images in the art gallery. However, the mobile device will only display an AR responsive to the mobile device being within a particular distance, for example four feet, from the AR image. This prevents the mobile device from displaying an AR for a piece of artwork that the user is not near and/or looking at. The AR can display the artist talking about their artwork and/or the artist creating the artwork, for example. 
       FIG.  5    illustrates an example of a computing device  500  used for displaying an AR in accordance with a number of embodiments of the present disclosure. Computing device  500  can correspond to computing device  400  in  FIG.  4   . Computing device  500  can include a processing resource  522 , a memory  524 , a user interface  502 , a camera  528 , and an AR platform  529 . The processing resource  522 , the memory  524 , the user interface  502 , the camera  528 , and the AR platform  529  can correspond to the processing resource  422 , the memory  424 , the user interface  402 , the camera  428 , and the AR platform  429 , respectively in  FIG.  4   . As illustrated in  FIG.  5   , computing device  500  can further include an AI accelerator  530 , an accelerometer  532 , a gyroscope  534 , and a global positioning system (GPS)  536 . 
     The AI accelerator  530  can include hardware and/or software/firmware, not shown, to perform AI operations. Data stored in memory  524  on the computing device  500  and/or external to the computing device  500  can be used in performing the AI operations. The data can include user data and/or AR data. User data can include a user&#39;s response to a notification that AR is available, a user&#39;s response to an AR, and/or user AR preferences. AR data can include AR data associated with an AR image received from an AR platform  529 . The AR data can include the creator, genre, content, and/or ratings of the AR, for example. 
     In some examples, the AI accelerator  530  can perform AI operations including machine learning or neural network operations, which may include training operations or inference operations, or both. The AR data and/or the user data can be used to perform AI operations to set user preferences. The user preferences can be set based on a user&#39;s previous responses to notifications and/or user&#39;s previous responses to AR. In some examples, the computing device  500  may not notify a user if an AR is available responsive to AR data including one or more characteristics in common with characteristics of a different AR a user has ignored before. For example, the computing device  500  may not notify a user if an AR is available responsive to the AR including particular content that the user has ignored before. 
     The accelerometer  532 , the gyroscope  534 , and/or the GPS  536  can be located on the computing device  500 , as illustrated in  FIG.  5   , or external to the computing device  500 . A location of the computing device  500  can be determined via the accelerometer  532 , the gyroscope  534 , and/or the GPS  536 . In some examples, an AR can be displayed responsive to a location of the computing device  500 . For example, an AR can be displayed when the location of the computing device  500  is within a particular distance of the AR image, when the location of the computing device  500  is within a particular area of an event, when the location of the computing device  500  is a particular distance away from a different location and/or, when the location of the computing device  500  is within a particular distance of a different location. 
       FIG.  6    is a flow diagram of a method  640  for displaying an AR responsive to an input in accordance with a number of embodiments of the present disclosure. At block  642 , the method  640  can include receiving first signaling including data representing at least one of: a timestamp, weather, an event, a rating, a user preference, a user input, or a location of a computing device at an AR platform of the computing device from a processing resource of the computing device. The computing device can be, for example, a personal laptop computer, a desktop computer, a smart phone, a tablet, a wrist-worn device, a digital camera, and/or redundant combinations thereof, among other types of computing devices. 
     At block  644 , the method  640  can include receiving second signaling including data representing an image at the AR platform of the computing device from a camera of the computing device. The computing device can include one or more cameras. One of the one or more cameras can be used solely for detecting AR images. In a number of embodiments, one or more optical sensors can be used with one or more cameras to detect an AR image or, in contrast, one or more optical sensors can be used instead of one or more cameras to detect an AR image. 
     At block  646 , the method  640  can include comparing the data representing the image to data representing a number of AR images included on the AR platform. An AR image can be an image that triggers an AR. 
     At block  648 , the method  640  can include determining at the AR platform that the image is an AR image of the number of AR images in response to a particular portion of the data representing the image matching data representing the AR image. The AR image can be associated with data representing an AR. The data representing an AR can be used to generate and display the AR. 
     At block  650 , the method  640  can include receiving at a user interface of the computing device third signaling including data representing an AR associated with the AR image from the AR platform in response to receiving the first signaling and determining the image is the AR image. The user interface can be generated by the computing device. The user interface can be a GUI that can provide and/or receive information to and/or from the user of the computing device. In some examples, the user interface can be shown on a display of the computing device. 
     At block  652 , the method  640  can include displaying the data representing the AR associated with the AR image on the user interface of the computing device in response to receiving the third signaling. AR can overlay virtual objects on a real-world environment to mask a portion of the real-world environment and/or add to the real-world environment such that it is perceived as an immersive aspect of the real-world environment. In some examples, AR can display and/or automate a number of images and/or enhance an AR image to move and/or change on the user interface. 
     In a number of embodiments, the method  640  can further include connecting the computing device to a Wi-Fi network, receiving fourth signaling including data representing the Wi-Fi network at the processing resource, and determining the data representing the location of the computing device using the data representing the Wi-Fi network at the processing resource. The AR platform can compare the data representing the location of the computing device to data representing a location of the AR image. In some examples, the user interface can receive the third signaling including the data representing the AR associated with the AR image from the AR platform in response to the computing device being within a particular distance of the AR image. 
     The method  640  can further include receiving the first signaling including the data representing the timestamp, determining at the AR platform the timestamp is at a particular time or within a particular time range, and receiving at the user interface the third signaling including the data representing the AR associated with the AR image from the AR platform in response to determining the timestamp is at the particular time or within the particular time range. 
     In some examples, the method  640  can further include receiving the first signaling including the data representing the weather, determining at the AR platform using the data representing the weather at least one of a temperature at a current location of the computing device being within a particular temperature range, a cloud coverage at the current location of the computing device being within a particular cloud coverage range, a precipitation at the current location of the computing device being within a particular precipitation range, or there being a storm at the current location of the computing device, and receiving at the user interface of the computing device the third signaling including the data representing the AR associated with the AR image from the AR platform in response to the determination at the AR platform. The weather can be determined using a sensor on the computing device or a sensor external to the computing device. 
     The method  640  can further include receiving the first signaling including the data representing the event, determining at the AR platform using the data representing the event at least one of the computing device being within a particular area of where the event is occurring or a time on the computing device being within a time period the event is scheduled for, and receiving at the user interface of the computing device the third signaling including the data representing the AR associated with the AR image from the AR platform in response to the determination at the AR platform.
