Abstract
Description
GENERATING PREVIEW IMAGES FOR OPTICAL SYSTEMSTECHNICAL FIELD
[0001] Embodiments of the present disclosure relate generally to generating preview images for optical systems, and, more particularly, but not by way of limitation, to methods and systems for providing an interactive interface on a publication platform to generate a preview image of a selected observation target based on parameters of the optical systems.BACKGROUND
[0002] Publication platforms offer a variety of optical system products, including cameras, lenses, telescopes, eyepieces, etc. However, current platforms do not support users in previewing the visual effects of these optical systems before purchase. Without precise visualization of what the products are capable of capturing or viewing, users’ experiences in purchasing optical systems online are severely limited.
[0003] For example, traditional methods require users to rely solely on technical specifications and static product images when evaluating optical systems. This approach makes it difficult for users, especially those unfamiliar with optical parameters like focal length, etc., to understand how the equipment will perform in real-world scenarios. The challenge is particularly significant when users need to match optical devices with specific observation targets or compare different optical configurations.
[0004] Additionally, users often struggle to determine the appropriate optical system specifications needed to achieve their desired viewing or imaging results. This can lead to purchasing equipment that does not meet their requirements, resulting in user dissatisfaction and product returns. The lack of interactive preview capabilities also makes it difficult for users to understand how adjustments to optical parameters would affect their viewing experience.BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The description that follows includes systems, methods, techniques, instruction sequences, and computing machine program products that embody illustrative embodiments of the present disclosure. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of embodiments. It will be evident, however, to one skilled in the art that the present inventive subject matter may be practiced without these specific details.
[0016] Reference in the specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present subject matter. Thus, the appearances of the phrase “in one embodiment” or “in an embodiment” appearing in various places throughout the specification are not necessarily all referring to the same embodiment.
[0017] For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the present subject matter. However, it will be apparent to one of ordinary skill in the art that embodiments of the subject matter described may be practiced without the specific details presented herein, or in various combinations, as described herein. Furthermore, well-known features may be omitted or simplified in order not to obscure the described embodiments. Various embodiments may be given throughout this description. These are merely descriptions of specific embodiments. The scope or meaning of the claims is not limited to the embodiments given.
[0018] Various embodiments include systems, methods, and non-transitory computer-readable media for generating preview images for optical systems on a publication platform (e.g., an e-commerce platform) . The optical system may include an optical device and / or an image formation device. The optical device may include a telescope or a lens for collecting and focusing light. The image formation device may include a camera with a sensor for capturing images or an eyepiece for direct viewing. The optical system works by the optical device gathering and directing light to the image formation device, which then either captures the image using a camera sensor or enables direct viewing through an eyepiece.
[0019] When browsing the publication platform, a user may view a product listing for either an optical device or an image formation device. The system provides an interactive interface that allows the user to select parameters for the other device (also referred to herein as a “complementary device” ) to make a potential combination of an optical system. For example, if a user is viewing a listing of a telescope, they can select parameters for different cameras or eyepieces to pair with it. The system determines the field of view (FOV) of the combined optical system based on the parameters of both the telescope and the selected complementary device. These parameters may include the focal length of the optical device, the sensor width of the camera, and / or the focal length or FOV of the eyepiece. The calculated FOV of the optical system represents the angular size of the area that can be captured or viewed through the combined optical system. For example, an optical system using a camera as the image formation device may have a rectangular FOV while an optical system using an eyepiece as the image formation device may have a circular FOV.
[0020] The system also enables users to select various types of observation targets through the interactive interface. The observation target may correspond to a position in a predetermined image stored in a database. For example, the system may access image databases containing different types of targets, such as astronomical objects, landscapes, wildlife, or other subjects of interest. The system can support both terrestrial and celestial observation targets by accessing the appropriate image databases for generating preview images. For astronomical targets, the system accesses a database containing celestial objects with their coordinates. Each celestial object may have specific coordinates comprising a right ascension (RA, also referred to as x-coordinate in the present disclosure) and / or a declination (DEC, also referred to as y-coordinate in the present disclosure) in an astronomical image. Users can select from predefined popular celestial objects like galaxies and nebulae, or input custom coordinates to locate specific targets. For terrestrial targets, the system similarly accesses appropriate image databases containing landscapes, wildlife, or other subjects. For terrestrial images, the user may supplement additional information such as their estimated location (e.g., Global Positioning System (GPS) location) of using the optical system, the estimated location (e.g., GPS location) of the observation target, etc. The user may upload their own images, but they may be requested to provide even more information.
[0021] After receiving the selection of an observation target, the system uses the FOV of the combined optical system to generate a preview image. Specifically, the system crops a portion of the predetermined image (or user-uploaded image) based on the coordinates of the selected observation target and the calculated FOV. For example, when a user selects a galaxy, the system uses its coordinates (RA and DEC) to locate the galaxy in the predetermined astronomical image, then crop or extract a part of the predetermined astronomical image matching the determined FOV dimensions of the optical system to create the preview image. The system may pre-adjust the preview image based on other optical characteristics of the optical system (e.g., resolution, magnification, tube dimensions, aperture size, etc. ) to provide a more accurate representation.
[0022] When viewing the preview image, the user may adjust the preview image by zooming or panning to explore different viewing configurations. When a user modifies the preview, the system automatically or upon request calculates the updated optical parameters needed to achieve the desired view. For example, if a user zooms in on a specific region of the Galaxy, the system determines the required FOV and back-calculates the parameters of the optical device or the image formation device. Based on these calculations, the system identifies and displays candidate devices available on the publication platform that match these updated parameters, such as specific telescope models with appropriate focal lengths.
[0023] The present disclosure provides significant technical improvements over conventional publication platforms. As mentioned above, traditional publication platforms only display static product images and specifications, requiring users to manually compare technical parameters and imagine how different optical configurations might perform. In contrast, the disclosed system provides dynamic, interactive previews based on actual optical parameters, enabling users to precisely visualize how different optical systems will capture or display their intended targets. The system’s automatic calculation and recommendation capabilities eliminate the need for users to have deep technical knowledge about optical parameters, as it can determine required specifications and suggest matching products based on desired viewing preferences. These technical improvements streamline the optical equipment shopping experience while ensuring users can make confident, well-informed decisions based on accurate visual previews rather than abstract specifications.
[0024] Reference will now be made in detail to embodiments of the present disclosure, examples of which are illustrated in the appended drawings. The present disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein.
[0025] FIG. 1 is a block diagram showing an example data system 100 that includes a publication system 122 (also referred to as system 122) , according to various embodiments of the present disclosure. As shown, the data system 100 includes one or more client devices 102, a server system 108, and a network 106 (e.g., Internet, wide-area-network (WAN) , local-area-network (LAN) , wireless network) that communicatively couples them together. Each client device 102 can host a number of applications, including a client software application 104. The client software application 104 can communicate data with the server system 108 via a network 106. Accordingly, the client software application 104 can communicate and exchange data with the server system 108 via network 106.
[0026] The server system 108 provides server-side functionality via the network 106 to the client software application 104. While certain functions of the data system 100 are described herein as being performed by the publication system 122 on the server system 108, it will be appreciated that the location of certain functionality within the server system 108 is a design choice. For example, it may be technically preferable to initially deploy certain technology and functionality within the server system 108, but to later migrate this technology and functionality to the client software application 104.
[0027] The server system 108 supports various services and operations that are provided to the client software application 104 by the publication system 122. Such operations include transmitting data from the publication system 122 to the client software application 104, receiving data from the client software application 104 at the publication system 122, and the publication system 122 processing data generated by the client software application 104. Data exchanges within the data system 100 may be invoked and controlled through operations of software component environments available via one or more endpoints, or functions available via one or more user interfaces of the client software application 104, which may include web-based user interfaces provided by the server system 108 for presentation at the client device 102.
[0028] With respect to the server system 108, an Application Program Interface (API) server 110 and a web server 112 is coupled to an application server 116, which hosts the publication system 122. The application server 116 is communicatively coupled to a database server 118, which facilitates access to a database 120 that stores data associated with the application server 116, including data that may be generated or used by the publication system 122.
[0029] The API server 110 receives and transmits data (e.g., API calls, commands, requests, responses, and authentication data) between the client device 102 and the application server 116. Specifically, the API server 110 provides a set of interfaces (e.g., routines and protocols) that can be called or queried by the client software application 104 in order to invoke the functionality of the application server 116. The API server 110 exposes various functions supported by the application server 116 including, without limitation, user registration; login functionality; data object operations (e.g., generating, storing, retrieving, encrypting, decrypting, transferring, access rights, licensing) ; and / or user communications.
[0030] The server system 108, or the publication system 122 may extract user data from one or more third-party platforms 124 (e.g., third-party social media platforms) .
[0031] Through one or more web-based interfaces (e.g., web-based user interfaces) , the web server 112 can support various functionality of the publication system 122 of the application server 116.
[0032] The publication system 122 interfaces with the application server 116 and database server (s) 118 to manage data flow within the server system. It coordinates with the database server (s) 118 to access and store data in the database (s) 120, enabling the system to retrieve and process optical system parameters and image data for generating preview images.
[0033] FIG. 2 is a diagram illustrating an example interactive interface 200 for selecting an optical system on a publication platform, according to various examples of the present disclosure. As used herein, an optical system may include an optical device and an image formation device. The optical device may include a lens or a telescope for collecting and focusing light. The image formation device may include a camera with a sensor for capturing images or an eyepiece for direct viewing through the optical device. The term “selecting an optical system” refers to viewing either the optical device or the image formation device on the publication platform while selecting the other device on an interactive interface of the publication platform to form a combined optical system. The selected device is also called a complementary device in the present disclosure. For example, if a user is viewing a telescope or a lens in the publication platform, a camera or an eyepiece is referred to as a complementary device, and vice versa.
[0034] The interactive interface 200 may include a search input field 202 and a search button 204. The search input field 202 may allow users to enter keywords, model numbers, specifications, or other search terms to find optical systems (or optical devices / image formation devices) on the publication platform. The search button 204 may initiate the search when clicked. The interactive interface 200 may also include a similar products section 206 that displays devices similar or related to the one that the user is currently viewing. The similar products section 206 may show optical systems with comparable specifications, price ranges, or intended uses to help users evaluate different options. For example, when viewing a telescope, the similar products section displays other telescopes with similar focal lengths, prices, or aperture sizes.
[0035] The interactive interface 200 may include an enlarged image 208 of the device that the user is currently viewing (hereinafter “current device” ) with a title 210 and a gallery of smaller images 212 of the current device. The title 210 may contain information that can identify the current device, such as brand name, model number, and key specifications of the current device. The gallery of images 212 may provide multiple views and angles of the current device, allowing users to check physical characteristics, such as the optical tube assembly, mount system, and accessories, of the current device. The interactive interface 200 may also include a specification section 214 that presents detailed technical parameters of the current device. For optical devices like telescopes or lenses, the specification section 214 may display parameters such as focal length, aperture size, optical design type (e.g., refracting, reflecting, or catadioptric) , and physical dimensions including tube length and weight. For image formation devices like cameras, the specification section 214 may display parameters such as sensor dimensions (e.g., APS-C or full-frame) , resolutions, supported features like autofocus compatibility, and other relevant technical specifications that affect the optical system’s performance.
[0036] The interactive interface 200 may further include an interactive interface 216. The interactive interface 216 allows the user to select a complementary device to combine with the current device to form a combined optical system. For example, when a telescope is currently viewed, the interactive interface 216 may include interactive section 218 of selectable cameras / eyepieces that are compatible with the telescope. A user may also select an observation target in the section 218. A preview image 220 of the observation target can be generated based on parameters of the combined optical system. Details regarding the interactive interface 216 can be found in FIGs. 3 and 4 and the descriptions thereof.
[0037] FIG. 3 is a diagram illustrating an example interactive interface 300 for generating a preview image 340 of a selected observation target for the optical system, according to various examples of the present disclosure. The interactive interface 300 is a more detailed version of the interactive interface 216, but there is no preference between them. Both interfaces 216 and 300 are within the protection scope of the present disclosure.
[0038] The interactive interface 300 may include a parameters section 302 of the current device. The parameters section 302 includes a selectable option 304 corresponding to the default parameters of the current device, such as a focal length of 480mm for a telescope. The parameters section 302 may also include a selectable option 306 for inputting customized parameters, allowing users to manually enter a different focal length value to explore alternative optical configurations.
[0039] The interactive interface 300 may include a parameters section 308 for selecting a complementary device to form a combined optical system with the currently viewed device. The parameters section 308 may include a selectable option 310 corresponding to preset complementary devices with dropdown lists 316 for selecting specific models and configurations. For example, a user can select between a camera or an eyepiece. In addition, the user can select a brand and model of the camera or eyepiece. For preset devices that exist in the dropdown lists 316, their specifications (e.g., parameters) are predetermined. The brand of a camera may include but is not limited to Canon, Nikon, Sony, Fujifilm, or Olympus. The brand of an eyepiece may include but not limited to Celestron, Vortex, Meade, Orion, or Swarovski. All these brands are exemplary and shall not be considered to be limiting. Other brands are within the protection scope of the present disclosure. As used herein, a camera Sony α1 is selected. This camera has a sensor size of 35.9 x 24 mm (full frame) . The parameters section 308 may also include selectable options 312 and 314 for inputting customized parameters of the complementary device - option 312 allows entering a custom camera sensor width, while option 314 allows entering eyepiece parameters, including focal length and field of view.
[0040] The interactive interface 300 may include an observation target section 318 for selecting observation targets. The observation target section 318 may include a selectable option 320 with dropdown lists 326 for choosing from predefined targets (e.g., the Andromeda Galaxy) . In some examples, the predefined targets may include nebulas (e.g., Orion Nebula, Crab Nebula, Eagle Nebula, Helix Nebula, Ring Nebula, Carina Nebula, Horsehead Nebula, etc. ) , galaxies (e.g., Andromeda Galaxy, Triangulum Galaxy, Whirlpool Galaxy, Sombrero Galaxy, Pinwheel Galaxy, etc. ) , landscapes (e.g., The Great Wall, Eiffel Tower, Mount Everest, Grand Canyon, Pyramids of Giza, Statue of Liberty, etc. ) . For nebulas and galaxies, the vast distances render the viewer's location on Earth negligible. However, for landscapes, the viewer’s specific location may need to be provided by the user to enable the system of the present disclosure to generate an accurate preview image. The predefined targets may have predetermined coordinates in a predetermined image. Users can alternatively select option 322 and upload their own reference picture (or image) through the upload button 328 and / or use option 324 to manually input specific coordinates through coordinate input fields 330.
[0041] The preview section 338 displays a preview image 340 (also referred to as an estimated image in the present disclosure) of how the selected target would likely appear if the user used the combined optical system. The preview includes coordinates 342 (e.g., 10.6847083, +41.2687500 for the Andromeda Galaxy) , a field of view indicator 344 showing the angular dimensions of the view (e.g., 4.28° x 2.86°) , and zoom controls 346 for adjusting the preview magnification. A user may interact with the preview image 340 and / or the zoom controls 346 to their desired coordinates and size. The update button 334, once clicked, can update the parameters 332 of the currently viewed device. The query button 336, once clicked, can display candidate devices having updated parameters 332. Details of updating the parameters and recommending candidate devices can be found in FIG. 4 and descriptions thereof.
[0042] FIG. 4 is a diagram illustrating an example interactive interface 300 for updating parameters 332 of the optical system and recommending candidate optical devices 414 and 416, according to various examples of the present disclosure. As shown in FIG. 4, a user may have updated the preview image section 402 by interacting with the zoom controls 346. The coordinates 408 of the observation target may be the same or different from before. The preview image 404 is updated, and the FOV 406 is updated. When a user zooms in, the FOV decreases (e.g., from 4.28° x 2.86° to 52.87’ x 32.81’ ) , and the focal length of the required telescope that is capable of having the decreased FOV is higher than before. The user may click on the update button 334 to update the suggested parameters 332 of the current device (e.g., the focal length of a telescope) . The user can then click on the query button 336 to cause a display of one or more candidate devices (e.g., telescopes 410 and 412) . If the user is interested in any of them, they can click on the corresponding “buy it! ” buttons 418 and 420 to be directed to a product listing page of the corresponding candidate device. In some examples, the update button 334 is omitted and the suggested parameters 332 is continuously updated and displayed. In some examples, a separate window including multiple candidate devices pops up when the user clicks the query button 336.
[0043] FIG. 5 is a diagram illustrating an exemplary astronomical image 500, according to various examples of the present disclosure. The astronomical image 500 is stored in a database accessible by the server system and represents a portion of the northern celestial hemisphere. An astronomical image of a southern celestial hemisphere or the entire celestial hemisphere or a portion thereof can also be used, and the astronomical image 500 is merely exemplary. As shown in FIG. 5, the astronomical image 500 employs a coordinate system using right ascension (RA) marked in hours (0h to 23h) and declination (DEC) marked in degrees (+0° to +90° for the northern celestial hemisphere and -90° to 0° for the southern celestial hemisphere) . This coordinate system allows the precise location of celestial objects, with the North Celestial Pole (NCP) and Polaris (the North Star) marked near the center at +90° declination. The astronomical image 500 contains many celestial objects and constellations. For example, the constellation Ursa Minor (Little Bear) is visible near the center, while Ursa Major (Great Bear) appears in the eastern portion of the image. The astronomical image 500 serves as a source for generating preview images of celestial objects. When a user selects an observation target through the interactive interface (e.g., interactive interface 216 or interactive interface 300) , the system uses the target’s coordinates (RA and DEC) to locate the corresponding region within this image.
[0044] For example, if a user selects the Andromeda Galaxy with predetermined coordinates (e.g., 10.6847083, +41.2687500) , the system locates this coordinates in the astronomical image 500 and extracts or crops the appropriate portion of the astronomical image 500 based on the calculated FOV of the selected optical system.
[0045] FIG. 6 is a flowchart illustrating an example method 600 for generating preview images for optical systems, according to various examples of the present disclosure. It will be understood that example methods described herein may be performed by a machine in accordance with some embodiments. For example, method 600 can be performed by the client device 102, the server system 108, or individual components thereof. An operation of method 600 may be performed by one or more hardware processors (e.g., central processing units or graphics processing units) of a computing device (e.g., a desktop, server, laptop, mobile phone, tablet, etc. ) , which may be part of a computing system based on a cloud architecture. The method 600 may also be implemented in the form of executable instructions stored on a machine-readable medium or in the form of electronic circuitry. For instance, the operations of method 600 may be represented by executable instructions that, when executed by a processor of a computing device, cause the computing device to perform method 600. Depending on the embodiment, an operation of the method 600 may be repeated in different ways or involve intervening operations not shown. Though the operations of the method 600 may be depicted and described in a certain order, the order in which the operations are performed may vary among embodiments, including performing certain operations in parallel.
[0046] At operation 602, a system (e.g., the publication system 122) receives a selection of an optical system on a publication platform. The optical system may include an optical device (e.g., a telescope or a lens) for collecting and focusing light, and an image formation device (e.g., a camera or an eyepiece) for capturing images or direct viewing. The selection of the optical system may include selecting one of the optical device and the image formation device on an interactive interface of the publication while viewing the other device.
[0047] At operation 604, the system obtains the parameters of the optical system. For optical devices, the parameters may include focal length (and optically aperture size, and optical design type) . For image formation devices, the parameters may include sensor dimensions for cameras or focal length and field of view for eyepieces.
[0048] At operation 606, the system determines a field of view (FOV) of the optical system based on the obtained parameters. The FOV calculation considers the optical device’s focal length combined with either the camera’s sensor width or the eyepiece’s FOV and focal length to determine the angular size of the observable area.
[0049] When a camera is used as the image formation device, the FOV of the optical system can be calculated as: FOV = 2*arctan (D / (2 * F) ) * (180 / π) (1) where D denotes the sensor width (mm) of the camera, and F denotes the focal length (mm) of the optical device.
[0050] When an eyepiece is used as the image formation device, the FOV of the optical system can be calculated as: FOV = E / F / L (2) where E denotes a FOV (°) of the eyepiece, F denotes the focal length (mm) of the optical device, and L denotes the focal length (mm) of the eyepiece.
[0051] Taking the combined optical system in FIG. 3 as an example, a SONY α1 camera (with a sensor size of 35.9 mm *24 mm, full frame) is used as the image formation device, and the telescope’s focal length is 480mm. Based on formula (1) , the FOV of the system is [2*arctan (35.9 / (2*480) ) * (180 / π) ] x [2*arctan (24 / (2*480) ) * (180 / π) ] = 4.28° x 2.86°.
[0052] At operation 608, the system receives a selection of an observation target. A user can select from predefined targets like galaxies and nebulae with known coordinates or input custom coordinates. For astronomical targets, coordinates include right ascension (RA) and declination (DEC) values that precisely locate the target in a predetermined astronomical image (e.g., astronomical image 500) .
[0053] At operation 610, the system generates a preview image of the selected observation target based on the calculated FOV of the optical system. The system accesses an appropriate image from image databases, locates the target using its coordinates, and extracts a portion of the image matching the optical system’s FOV dimensions. The preview image represents an estimated view through the optical system.
[0054] At operation 612, the system causes display of the preview image by the publication platform. The preview includes coordinate information, FOV indicators showing angular dimensions, and interactive controls allowing the user to adjust the view. The user can zoom, pan, and explore different viewing configurations while the system dynamically updates the preview image. Details regarding updating the preview image and recommending candidate optical systems based on the updated preview image may be found in FIG. 7 and descriptions thereof.
[0055] In some examples, method 600 may further include receiving, from the user via the interactive interface, selections of a plurality of optical systems on the publication platform; generating a plurality of preview images of the observation target corresponding to the plurality of optical systems; and causing display, on the interactive interface, of the plurality of preview images of the observation target corresponding to the plurality of optical systems.
[0056] In some examples, method 600 may further include receiving, from a first user, a user image of the observation target, the user image being captured by the first user using the optical system and providing the user image of the observation target and the preview image of the observation target to a second user.
[0057] FIG. 7 is a flowchart illustrating an example method 700 for recommending candidate optical systems based on an updated preview image, according to various examples of the present disclosure. It will be understood that example methods described herein may be performed by a machine in accordance with some embodiments. For example, method 700 can be performed by the client device 102, the server system 108, or individual components thereof. An operation of method 700 may be performed by one or more hardware processors (e.g., central processing units or graphics processing units) of a computing device (e.g., a desktop, server, laptop, mobile phone, tablet, etc. ) , which may be part of a computing system based on a cloud architecture. The method 700 may also be implemented in the form of executable instructions stored on a machine-readable medium or in the form of electronic circuitry. For instance, the operations of method 700 may be represented by executable instructions that, when executed by a processor of a computing device, cause the computing device to perform method 700. Depending on the embodiment, an operation of the method 700 may be repeated in different ways or involve intervening operations not shown. Though the operations of the method 700 may be depicted and described in a certain order, the order in which the operations are performed may vary among embodiments, including performing certain operations in parallel. Method 700 may follow the method 600.
[0058] At operation 702, a system (e.g., the publication system 122) receives an adjustment of the preview image from a user via an interactive interface. The adjustment may include zooming, panning, or other modifications to explore different viewing configurations of the observation target.
[0059] At operation 704, the system determines an updated field of view (FOV) of the optical system after the user’s adjustment. For example, when a user zooms in on a specific region of a celestial object, the FOV decreases (e.g., from 4.28° x 2.86° to 52.87’ x 32.81’ ) , indicating a need for different optical parameters (e.g., higher focal length) to achieve the desired view.
[0060] At operation 706, the system determines the updated parameters of the optical system based on the updated FOV. The system back-calculates (e.g., based on formula (1) or formula (2) ) the required parameters, such as focal length for telescopes or lenses, sensor dimensions for cameras, or FOV / focal length for eyepieces, that would achieve the adjusted view. Using the updated FOV in FIG. 4 as an example, based on formula (1) , in order to have a FOV of 52.87' x 32.81', the telescope should have a focal length of 35.9 / (tan (52.87 / 60*π / 180 / 2) ) / 2 = 2334 mm.
[0061] At operation 708, the system causes a display of one or more candidate optical systems or parts thereof with the updated parameters. For example, the system may identify and display specific telescope models available on the publication platform that match the calculated parameters (e.g., Celestron NexStar Evolution Series 9.25" Telescope or Sky-Watcher 180mm Maksutov-Cassegrain, each of which having a focal length close to the calculated 2334 mm) . Each candidate device may be displayed along with a “Buy it! ” button that directs users to the corresponding product listing.
[0062] FIG. 8 is a block diagram illustrating an example of a software architecture 802 that may be installed on a machine, according to some example embodiments. FIG. 8 is merely a non-limiting example of a software architecture, and it will be appreciated that many other architectures may be implemented to facilitate the functionality described herein. The software architecture 802 may be executing on hardware such as a machine 900 of FIG. 9 that includes, among other things, processors 910, memory 930, and input / output (I / O) components 950. A representative hardware layer 804 is illustrated and can represent, for example, the machine 900 of FIG. 9. The representative hardware layer 804 comprises one or more processing units 806 having associated executable instructions 808. The executable instructions 808 represent the executable instructions of the software architecture 802. The hardware layer 804 also includes memory or storage modules 810, which also have the executable instructions 808. The hardware layer 804 may also comprise other hardware 812, which represents any other hardware of the hardware layer 804, such as the other hardware illustrated as part of the machine 900.
[0063] In the example architecture of FIG. 8, the software architecture 802 may be conceptualized as a stack of layers, where each layer provides particular functionality. For example, the software architecture 802 may include layers such as an operating system 814, libraries 816, frameworks / middleware 818, applications 820, and a presentation layer 844. Operationally, the applications 820 or other components within the layers may invoke API calls 824 through the software stack and receive a response, returned values, and so forth (illustrated as messages 826) in response to the API calls 824. The layers illustrated are representative in nature, and not all software architectures have all layers. For example, some mobile or special-purpose operating systems may not provide a frameworks / middleware 818 layer, while others may provide such a layer. Other software architectures may include additional or different layers.
[0064] The operating system 814 may manage hardware resources and provide common services. The operating system 814 may include, for example, a kernel 828, services 830, and drivers 832. The kernel 828 may act as an abstraction layer between the hardware and the other software layers. For example, the kernel 828 may be responsible for memory management, processor management (e.g., scheduling) , component management, networking, security settings, and so on. The services 830 may provide other common services for the other software layers. The drivers 832 may be responsible for controlling or interfacing with the underlying hardware. For instance, the drivers 832 may include display drivers, camera drivers, drivers, flash memory drivers, serial communication drivers (e.g., Universal Serial Bus (USB) drivers) , drivers, audio drivers, power management drivers, and so forth depending on the hardware configuration.
[0065] The libraries 816 may provide a common infrastructure that may be utilized by the applications 820 and / or other components and / or layers. The libraries 816 typically provide functionality that allows other software modules to perform tasks in an easier fashion than by interfacing directly with the underlying operating system 814 functionality (e.g., kernel 828, services 830, or drivers 832) . The libraries 816 may include system libraries 834 (e.g., C standard library) that may provide functions such as memory allocation functions, string manipulation functions, mathematic functions, and the like. In addition, the libraries 816 may include API libraries 836 such as media libraries (e.g., libraries to support presentation and manipulation of various media formats such as MPEG4, H. 264, MP3, AAC, AMR, JPG, and PNG) , graphics libraries (e.g., an OpenGL framework that may be used to render 2D and 3D graphic content on a display) , database libraries (e.g., SQLite that may provide various relational database functions) , web libraries (e.g., WebKit that may provide web browsing functionality) , and the like. The libraries 816 may also include a wide variety of other libraries 838 to provide many other APIs to the applications 820 and other software components / modules.
[0066] The frameworks 818 (also sometimes referred to as middleware) may provide a higher-level common infrastructure that may be utilized by the applications 820 or other software components / modules. For example, the frameworks 818 may provide various graphical user interface functions, high-level resource management, high-level location services, and so forth. The frameworks 818 may provide a broad spectrum of other APIs that may be utilized by the applications 820 and / or other software components / modules, some of which may be specific to a particular operating system or platform.
[0067] The applications 820 include built-in applications 840 and / or third-party applications 842. Examples of representative built-in applications 840 may include, but are not limited to, a home application, a contacts application, a browser application, a book reader application, a location application, a media application, a messaging application, or a game application.
[0068] The third-party applications 842 may include any of the built-in applications 840, as well as a broad assortment of other applications. In a specific example, the third-party applications 842 (e.g., an application developed using the AndroidTM or iOSTM software development kit (SDK) by an entity other than the vendor of the particular platform) may be mobile software running on a mobile operating system such as iOSTM, AndroidTM, or other mobile operating systems. In this example, the third-party applications 842 may invoke the API calls 824 provided by the mobile operating system such as the operating system 814 to facilitate functionality described herein.
[0069] The applications 820 may utilize built-in operating system functions (e.g., kernel 828, services 830, or drivers 832) , libraries (e.g., system libraries 834, API libraries 836, and other libraries 838) , or frameworks / middleware 818 to create user interfaces to interact with users of the system. Alternatively, or additionally, in some systems, interactions with a user may occur through a presentation layer, such as the presentation layer 844. In these systems, the application / module “logic” can be separated from the aspects of the application / module that interact with the user.
[0070] Some software architectures utilize virtual machines. In the example of FIG. 8, this is illustrated by a virtual machine 848. The virtual machine 848 creates a software environment where applications / modules can execute as if they were executing on a hardware machine (e.g., the machine 800 of FIG. 9) . The virtual machine 848 is hosted by a host operating system (e.g., the operating system 814) and typically, although not always, has a virtual machine monitor 846, which manages the operation of the virtual machine 848 as well as the interface with the host operating system (e.g., the operating system 814) . A software architecture executes within the virtual machine 848, such as an operating system 850, libraries 852, frameworks 854, applications 856, or a presentation layer 858. These layers of software architecture executing within the virtual machine 848 can be the same as corresponding layers previously described or may be different.
[0071] FIG. 9 illustrates a diagrammatic representation of a machine 900 in the form of a computer system within which a set of instructions may be executed for causing the machine 900 to perform any one or more of the methodologies discussed herein, according to an embodiment. Specifically, FIG. 9 shows a diagrammatic representation of the machine 900 in the example form of a computer system, within which instructions 916 (e.g., software, a program, an application, an applet, an app, or other executable code) for causing the machine 900 to perform any one or more of the methodologies discussed herein may be executed. For example, the instructions 916 may cause the machine 900 to execute the method 600 described above with respect to FIG. 6 and the method 700 described above with respect to FIG. 7. The instructions 916 transform the general, non-programmed machine 900 into a particular machine 900 programmed to carry out the described and illustrated functions in the manner described. In alternative embodiments, the machine 900 operates as a standalone device or may be coupled (e.g., networked) to other machines. In a networked deployment, the machine 900 may operate in the capacity of a server machine or a client machine in a server-client network environment, or as a peer machine in a peer-to-peer (or distributed) network environment. The machine 900 may comprise, but not be limited to, a server computer, a client computer, a personal computer (PC) , a tablet computer, a laptop computer, a netbook, a personal digital assistant (PDA) , an entertainment media system, a cellular telephone, a smart phone, a mobile device, or any machine capable of executing the instructions 916, sequentially or otherwise, that specify actions to be taken by the machine 900. Further, while only a single machine 900 is illustrated, the term “machine” shall also be taken to include a collection of machines 900 that individually or jointly execute the instructions 916 to perform any one or more of the methodologies discussed herein.
[0072] The machine 900 may include processors 910, memory 930, and I / O components 950, which may be configured to communicate with each other such as via a bus 902. In an embodiment, the processors 910 (e.g., a hardware processor, such as a central processing unit (CPU) , a reduced instruction set computing (RISC) processor, a complex instruction set computing (CISC) processor, a graphics processing unit (GPU) , a digital signal processor (DSP) , an application-specific integrated circuit (ASIC) , a radio-frequency integrated circuit (RFIC) , another processor, or any suitable combination thereof) may include, for example, a processor 912 and a processor 914 that may execute the instructions 916. The term “processor” is intended to include multi-core processors that may comprise two or more independent processors (sometimes referred to as “cores” ) that may execute instructions contemporaneously. Although FIG. 9 shows multiple processors 910, the machine 900 may include a single processor with a single core, a single processor with multiple cores (e.g., a multi-core processor) , multiple processors with a single core, multiple processors with multiples cores, or any combination thereof.
[0073] The memory 930 may include a main memory 932, a static memory 934, and a storage unit 936 including machine-readable medium 938, each accessible to the processors 910 such as via the bus 902. The main memory 932, the static memory 934, and the storage unit 936 store the instructions 916 embodying any one or more of the methodologies or functions described herein. The instructions 916 may also reside, completely or partially, within the main memory 932, within the static memory 934, within the storage unit 936, within at least one of the processors 910 (e.g., within the processor’s cache memory) , or any suitable combination thereof, during execution thereof by the machine 900.
[0074] The I / O components 950 may include a wide variety of components to receive input, provide output, produce output, transmit information, exchange information, capture measurements, and so on. The specific I / O components 950 that are included in a particular machine will depend on the type of machine. For example, portable machines such as mobile phones will likely include a touch input device or other such input mechanisms, while a headless server machine will likely not include such a touch input device. It will be appreciated that the I / O components 950 may include many other components that are not shown in FIG. 9. The I / O components 950 are grouped according to functionality merely for simplifying the following discussion, and the grouping is in no way limiting. In some examples, the I / O components 950 may include output components 952 and input components 954. The output components 952 may include visual components (e.g., a display such as a plasma display panel (PDP) , a light-emitting diode (LED) display, a liquid crystal display (LCD) , a projector, or a cathode ray tube (CRT) ) , acoustic components (e.g., speakers) , haptic components (e.g., a vibratory motor, resistance mechanisms) , other signal generators, and so forth. The input components 954 may include alphanumeric input components (e.g., a keyboard, a touch screen configured to receive alphanumeric input, a photo-optical keyboard, or other alphanumeric input components) , point-based input components (e.g., a mouse, a touchpad, a trackball, a joystick, a motion sensor, or another pointing instrument) , tactile input components (e.g., a physical button, a touch screen that provides location and / or force of touches or touch gestures, or other tactile input components) , audio input components (e.g., a microphone) , and the like.
[0075] In further embodiments, the I / O components 950 may include biometric components 956, motion components 958, environmental components 960, or position components 962, among a wide array of other components. The motion components 958 may include acceleration sensor components (e.g., accelerometer) , gravitation sensor components, rotation sensor components (e.g., gyroscope) , and so forth. The environmental components 960 may include, for example, illumination sensor components (e.g., photometer) , temperature sensor components (e.g., one or more thermometers that detect ambient temperature) , humidity sensor components, pressure sensor components (e.g., barometer) , acoustic sensor components (e.g., one or more microphones that detect background noise) , proximity sensor components (e.g., infrared sensors that detect nearby objects) , gas sensors (e.g., gas detection sensors to detect concentrations of hazardous gases for safety or to measure pollutants in the atmosphere) , or other components that may provide indications, measurements, or signals corresponding to a surrounding physical environment. The position components 962 may include location sensor components (e.g., a Global Positioning System (GPS) receiver component) , altitude sensor components (e.g., altimeters or barometers that detect air pressure from which altitude may be derived) , orientation sensor components (e.g., magnetometers) , and the like.
[0076] Communication may be implemented using a wide variety of technologies. The I / O components 950 may include communication components 964 operable to couple the machine 900 to a network 980 or devices 970 via a coupling 982 and a coupling 972, respectively. For example, the communication components 964 may include a network interface component or another suitable device to interface with the network 980. In further examples, the communication components 964 may include wired communication components, wireless communication components, cellular communication components, near field communication (NFC) components, components (e.g., Low Energy) , components, and other communication components to provide communication via other modalities. The devices 970 may be another machine or any of a wide variety of peripheral devices (e.g., a peripheral device coupled via a USB) .
[0077] Moreover, the communication components 964 may detect identifiers or include components operable to detect identifiers. For example, the communication components 964 may include radio frequency identification (RFID) tag reader components, NFC smart tag detection components, optical reader components (e.g., an optical sensor to detect one-dimensional bar codes such as Universal Product Code (UPC) bar code, multi-dimensional bar codes such as Quick Response (QR) code, Aztec code, Data Matrix, Dataglyph, MaxiCode, PDF417, Ultra Code, UCC RSS-2D bar code, and other optical codes) , or acoustic detection components (e.g., microphones to identify tagged audio signals) . In addition, a variety of information may be derived via the communication components 964, such as location via Internet Protocol (IP) geolocation, location via signal triangulation, location via detecting an NFC beacon signal that may indicate a particular location, and so forth.
[0078] Certain embodiments are described herein as including logic or a number of components, modules, elements, or mechanisms. Such modules can constitute either software modules (e.g., code embodied on a machine-readable medium or in a transmission signal) or hardware modules. A “hardware module” is a tangible unit capable of performing certain operations and can be configured or arranged in a certain physical manner. In various example embodiments, one or more computer systems (e.g., a standalone computer system, a client computer system, or a server computer system) or one or more hardware modules of a computer system (e.g., a processor or a group of processors) are configured by software (e.g., an application or application portion) as a hardware module that operates to performcertain operations as described herein.
[0079] In some examples, a hardware module is implemented mechanically, electronically, or any suitable combination thereof. For example, a hardware module can include dedicated circuitry or logic that is permanently configured to perform certain operations. For example, a hardware module can be a special-purpose processor, such as a field-programmable gate array (FPGA) or an ASIC. A hardware module may also include programmable logic or circuitry that is temporarily configured by software to perform certain operations. For example, a hardware module can include software encompassed within a general-purpose processor or other programmable processor. It will be appreciated that the decision to implement a hardware module mechanically, in dedicated and permanently configured circuitry, or in temporarily configured circuitry (e.g., configured by software) can be driven by cost and time considerations.
[0080] Accordingly, the phrase “module” should be understood to encompass a tangible entity, be that an entity that is physically constructed, permanently configured (e.g., hardwired) , or temporarily configured (e.g., programmed) to operate in a certain manner or to perform certain operations described herein. Considering embodiments in which hardware modules are temporarily configured (e.g., programmed) , each of the hardware modules need not be configured or instantiated at any one instance in time. For example, where a hardware module comprises a general-purpose processor configured by software to become a special-purpose processor, the general-purpose processor may be configured as respectively different special-purpose processors (e.g., comprising different hardware modules) at different times. Software can accordingly configure a particular processor or processors, for example, to constitute a particular hardware module at one instance of time and to constitute a different hardware module at a different instance of time.
[0081] Hardware modules can provide information to, and receive information from, other hardware modules. Accordingly, the described hardware modules can be regarded as being communicatively coupled. Where multiple hardware modules exist contemporaneously, communications can be achieved through signal transmission (e.g., over appropriate circuits and buses) between or among two or more of the hardware modules. In embodiments in which multiple hardware modules are configured or instantiated at different times, communications between or among such hardware modules may be achieved, for example, through the storage and retrieval of information in memory structures to which the multiple hardware modules have access. For example, one hardware module performs an operation and stores the output of that operation in a memory device to which it is communicatively coupled. A further hardware module can then, at a later time, access the memory device to retrieve and process the stored output. Hardware modules can also initiate communications with input or output devices, and can operate on a resource (e.g., a collection of information) .
[0082] The various operations of example methods described herein can be performed, at least partially, by one or more processors that are temporarily configured (e.g., by software) or permanently configured to perform the relevant operations. Whether temporarily or permanently configured, such processors constitute processor-implemented modules that operate to perform one or more operations or functions described herein. As used herein, “processor-implemented module” refers to a hardware module implemented using one or more processors.
[0083] Similarly, the methods described herein can be at least partially processor-implemented, with a particular processor or processors being an example of hardware. For example, at least some of the operations of a method can be performed by one or more processors or processor-implemented modules. Moreover, the one or more processors may also operate to support performance of the relevant operations in a “cloud computing” environment or as a “software as a service” (SaaS) . For example, at least some of the operations may be performed by a group of computers (as examples of machines 900 including processors 910) , with these operations being accessible via a network (e.g., the Internet) and via one or more appropriate interfaces (e.g., an API) . In certain embodiments, for example, a client device may relay or operate in communication with cloud computing systems and may access circuit design information in a cloud environment.
[0084] The performance of certain of the operations may be distributed among the processors, not only residing within a single machine 900, but deployed across a number of machines 900. In some example embodiments, the processors 910 or processor-implemented modules are located in a single geographic location (e.g., within a home environment, an office environment, or a server farm) . In other example embodiments, the processors or processor-implemented modules are distributed across a number of geographic locations.
[0085] The various memories and / or the storage unit 936 may store one or more sets of instructions 916 and data structures (e.g., software) embodying or utilized by any one or more of the methodologies or functions described herein. These instructions (e.g., the instructions 916) , when executed by the processor (s) , cause various operations to implement the disclosed embodiments.
[0086] As used herein, the terms “machine-storage medium, ” “device-storage medium, ” and “computer-storage medium” mean the same thing and may be used interchangeably. The terms refer to a single or multiple storage devices and / or media (e.g., a centralized or distributed database, and / or associated caches and servers) that store executable instructions 916 and / or data. The terms shall accordingly be taken to include, but not be limited to, solid-state memories, and optical and magnetic media, including memory internal or external to processors. Specific examples of machine-storage media, computer-storage media and / or device-storage media include non-volatile memory, including by way of example semiconductor memory devices, e.g., erasable programmable read-only memory (EPROM) , electrically erasable programmable read-only memory (EEPROM) , FPGA, and flash memory devices; magnetic disks such as internal hard disks and removable disks; magneto-optical disks; and CD-ROM and DVD-ROM disks. The terms “machine-storage media, ” “computer-storage media, ” and “device-storage media” specifically exclude carrier waves, modulated data signals, and other such media, at least some of which are covered under the term “signal medium” discussed below.
[0087] In some examples, one or more portions of the network 980 may be an ad hoc network, an intranet, an extranet, a virtual private network (VPN) , a LAN, a wireless LAN (WLAN) , a WAN, a wireless WAN (WWAN) , a metropolitan-area network (MAN) , the Internet, a portion of the Internet, a portion of the public switched telephone network (PSTN) , a plain old telephone service (POTS) network, a cellular telephone network, a wireless network, a network, another type of network, or a combination of two or more such networks. For example, the network 980 or a portion of the network 980 may include a wireless or cellular network, and the coupling 982 may be a Code Division Multiple Access (CDMA) connection, a Global System for Mobile communications (GSM) connection, or another type of cellular or wireless coupling. In this example, the coupling 982 may implement any of a variety of types of data transfer technology, such as Single Carrier Radio Transmission Technology (1xRTT) , Evolution-Data Optimized (EVDO) technology, General Packet Radio Service (GPRS) technology, Enhanced Data rates for GSM Evolution (EDGE) technology, third Generation Partnership Project (3GPP) including 3G, fourth generation wireless (4G) networks, Universal Mobile Telecommunications System (UMTS) , High-Speed Packet Access (HSPA) , Worldwide Interoperability for Microwave Access (WiMAX) , Long-Term Evolution (LTE) standard, others defined by various standard-setting organizations, other long-range protocols, or other data transfer technology.
[0088] The instructions may be transmitted or received over the network using a transmission medium via a network interface device (e.g., a network interface component included in the communication components) and utilizing any one of a number of well-known transfer protocols (e.g., hypertext transfer protocol (HTTP) ) . Similarly, the instructions may be transmitted or received using a transmission medium via the coupling (e.g., a peer-to-peer coupling) to the devices 970. The terms “transmission medium” and “signal medium” mean the same thing and may be used interchangeably in this disclosure. The terms “transmission medium” and “signal medium” shall be taken to include any intangible medium that is capable of storing, encoding, or carrying the instructions for execution by the machine, and include digital or analog communications signals or other intangible media to facilitate communication of such software. Hence, the terms “transmission medium” and “signal medium” shall be taken to include any form of modulated data signal, carrier wave, and so forth. The term “modulated data signal” means a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal.
[0089] The terms “machine-readable medium, ” “computer-readable medium, ” and “device-readable medium” mean the same thing and may be used interchangeably in this disclosure. The terms are defined to include both machine-storage media and transmission media. Thus, the terms include both storage devices / media and carrier waves / modulated data signals.
[0090] Throughout this specification, plural instances may implement resources, components, operations, or structures described as a single instance. Although individual operations of one or more methods are illustrated and described as separate operations, one or more of the individual operations may be performed concurrently, and nothing requires that the operations be performed in the order illustrated. Structures and functionality presented as separate components in example configurations may be implemented as a combined structure or component. Similarly, structures and functionality presented as a single component may be implemented as separate components.
[0091] As used herein, the term “or” may be construed in either an inclusive or exclusive sense. The terms “a” or “an” should be read as meaning “at least one, ” “one or more, ” or the like. The presence of broadening words and phrases such as “one or more, ” “at least, ” “but not limited to, ” or other like phrases in some instances shall not be read to mean that the narrower case is intended or required in instances where such broadening phrases may be absent. Additionally, boundaries between various resources, operations, modules, engines, and data stores are somewhat arbitrary, and particular operations are illustrated in a context of specific illustrative configurations. Other allocations of functionality are envisioned and may fall within a scope of various embodiments of the present disclosure. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
[0092] It will be understood that changes and modifications may be made to the disclosed embodiments without departing from the scope of the present disclosure. These and other changes or modifications are intended to be included within the scope of the present disclosure.
