The present invention will now be described in detail with reference to the Figures. FIG. 1 is a functional block diagram illustrating a data processing environment, generally designated 100, in accordance with an embodiment of the present invention. FIG. 1 provides only an illustration of one implementation and does not imply any limitations with regard to the environments in which different embodiments may be implemented. Many modifications to the depicted environment may be made by those skilled in the art without departing from the scope of the invention as recited by the claims. FIG. 1 includes network 102, server 104, and one or more client devices, such as client device 106 and client device 108.
In one embodiment, network 102 is the Internet representing a worldwide collection of networks and gateways that use TCP/IP protocols to communicate with one another. Network 102 may include wire cables, wireless communication links, fiber optic cables, routers, switches, and/or firewalls. Server 104, client device 106, and client device 108 are interconnected by network 102. Network 102 can be any combination of connections and protocols capable of supporting communications between server 104, client device 106, client device 108, and URL program 110. Network 102 may also be implemented as a number of different types of networks, such as an intranet, a local area network (LAN), a virtual local area network (VLAN), or a wide area network (WAN). FIG. 1 is intended as an example and not as an architectural limitation for the different embodiments.
In one embodiment, server 104 may be, for example, a server computer system, such as a management server, a web server, or any other electronic device or computing system capable of sending and receiving data. In another embodiment, server 104 may be a data center consisting of a collection of networks and servers providing an IT service, such as virtual servers and applications deployed on virtual servers, to an external party. In another embodiment, server 104 represents a “cloud” of computers interconnected by one or more networks, where server 104 is a computing system utilizing clustered computers and components to act as a single pool of seamless resources when accessed through network 102. This is a common implementation for data centers in addition to cloud computing applications. In the exemplary embodiment, server 104 includes URL program 110 for creating clickable web links within collaborative web meetings.
In one embodiment, URL program 110 operates on a central server, such as server 104, and can be utilized by one or more client devices, such as client device 106 and client device 108, via network 102. In another embodiment, URL program 110 may be a software-based program downloaded from the central server, such as server 104, or a third-party provider (not shown), and executed on a client device, such as client device 106 and client device 108, to create clickable web links within a collaborative web meeting. In another embodiment, URL program 110 may be a software-based program, downloaded from a central server, such as server 104, and installed on one or more client devices, such as client device 106 and client device 108. In yet another embodiment, URL program 110 may be utilized as a software service provided by a third-party cloud service provider (not shown). In yet another embodiment, URL program 110 may include one or more software-based components, such as add-ons, plug-ins, and agent programs, etc., installed on one or more client devices, such as client device 106 and client device 108, for creating clickable web links within collaborative web meetings.
In one embodiment, URL program 110 is a software-based program for creating clickable web links within collaborative web meetings. In one embodiment, URL program 110 provides the capability for a user (i.e., a remote participant of a collaborative web meeting) to click on web links presented within the content of a slide of a presentation during a live session of a collaborative web meeting. In some embodiments, URL program 110 may provide the capability for a user to click on web links presented within content of web conferences, educational presentations, training modules, etc., or any other type of live meeting where content from an original presentation on a host computer is presented as a rendered image to one or more users in a live web-based collaborative learning environment. In one embodiment, URL program 110 provides the capability to identify one or more web links (e.g., URLs) within a presentation during a live collaborative web meeting session. In one embodiment, URL program 110 includes one or more server-side components for scanning each slide of a presentation to identify one or more web links (i.e., URLs) within each slide. In one embodiment, URL program 110 includes one or more client-side components for creating a clickable link for one or more identified web links within each slide in a presentation. In one embodiment, URL program 110 provides the capability to create a clickable link at a position within a slide of a presentation where a web link is presented, such that during a live collaborative web meeting session a remote participant can utilize the web link to browse related additional information and resources provided by the web link.
In the exemplary embodiment, client device 106 and client device 108 are clients to server 104 and may be, for example, a desktop computer, a laptop computer, a tablet computer, a personal digital assistant (PDA), a smart phone, a thin client, or any other electronic device or computing system capable of communicating with server 104 through network 102. For example, client device 106 and client device 108 may be a laptop computer capable of connecting to a network, such as network 102, to host or participate in a collaborative web meeting and communicate with a central server to utilize a software-based program, such as URL program 110 of server 104. In one embodiment, client device 106 and client device 108 may be any suitable type of mobile device capable of running mobile applications, including a smart phone, tablet, slate, or any type of device that runs a mobile operating system and is capable of connecting to a network, such as network 102, to host or participate in a collaborative web meeting. In one embodiment, client device 106 and client device 108 include a user interface (not shown) for utilizing a clickable link within a collaborative web meeting where the user interface refers to the information (such as graphic, text, and sound) a program presents to a user and the control sequences the user employs to control the program. There are many types of user interfaces. In one embodiment, the user interface may be a graphical user interface (GUI). A GUI is a type of user interface that allows users to interact with electronic devices, such as a keyboard and mouse, through graphical icons and visual indicators, such as secondary notations, as opposed to text-based interfaces, typed command labels, or text navigation. In computers, GUIs were introduced in reaction to the perceived steep learning curves of command-line interfaces, which required commands to be typed on the keyboard. The actions in GUIs are often performed through direct manipulation of the graphics elements.
FIG. 2 depicts a flowchart of operational steps of a URL program, such as URL program 110 of FIG. 1, generally designated 200, for creating clickable links within live collaborative web meetings, in accordance with an embodiment of the present invention.
URL program 110 identifies one or more URLs in a presentation (202). In one embodiment, URL program 110 identifies one or more URLs in a presentation by scanning a plurality of slides within the presentation for one or more URLs. In some embodiments, a presentation may be a process of presenting a topic to an audience, such as during a lecture, a demonstration, a training seminar, or a speech. In other embodiments, a presentation may include Internet-based presentation programs, as well as presentation software used to generate presentation content as a visualization for an audience. In one embodiment, URL program 110 utilizes a server-side component, such as a conventional text scanner, to scan each slide in a plurality of slides within a presentation to identify URL text patterns or active hyperlinks. In one embodiment, URL program 110 performs a scan for one or more URLs whenever a presentation is uploaded from a host computer to a collaborative web meeting as a rendered image to share the presentation content globally with one or more remote participants.
In another embodiment, URL program 110 may utilize a participant client-side plug-in to leverage optical character recognition (OCR) techniques to identify text within a slide of a presentation (i.e., an image) and further identify which of the identified text within the slide are URLs. In this embodiment, URL program 110 may utilize OCR techniques to monitor a plurality of images within the presentation for URL patterns and identify any URL text patterns within a slide of the presentation (i.e., image screens being shared during a live collaborative web meeting session).
URL program 110 retrieves metadata for the one or more URLs in the presentation (204). In one embodiment, URL program 110 retrieves metadata for the one or more URLs in the presentation by extracting information (i.e., metadata) related to each of the one or more identified URLs, where information related to each of the one or more identified URLs includes, without limitation, actual URL text, a page number from the presentation (e.g., a slide number) where an identified URL exists, and a position of an identified URL within a slide of the presentation. For example, URL program 110 may extract actual URL text, such as “http://www.abcdef.com,” a page number of a slide that the URL belongs to, such as “slide 18,” and a position within the slide where the URL is located, such as “second bullet point, after the fourth word.” In one embodiment, URL program 110 stores the metadata for each of the one or more URLs in a database (not shown) for future retrieval.
URL program 110 presents the metadata for each of the one or more URLs with a corresponding image within the presentation (206). In one embodiment, URL program 110 presents the metadata for each of the one or more URLs with a corresponding image (i.e., slide) within the presentation whenever a slide containing a URL is presented to a client device, such as client device 106 and client device 108, during a live collaborative web meeting. In one embodiment, when a slide containing a URL is presented during a live collaborative web meeting, URL program 110 utilizes a server-side component to retrieve the metadata for each of the one or more URLs identified within the slide stored in a database and further overlays the metadata at a position within the corresponding image where each of the one or more URLs were originally located in the presentation.
URL program 110 creates a clickable link for each of the one or more URLs within the corresponding image (208). In one embodiment, URL program 110 creates a clickable link for each of the one or more URLs within the corresponding image by identifying a position within the image where an overlay of the metadata for each of the one or more URLs is located and further enables the overlay of the metadata for each of the one or more URLs to function as a clickable link at a position within the image that mirrors an original position of each URL in the presentation. In some embodiments, URL program 110 may enable the overlay of the metadata for each of the one or more URLs to function as a clickable link by generating a hyperlink or web link using the metadata as an additional layer on top of the image or by any other suitable methods known in the art for overlaying data on an image and creating hyperlinks. In some embodiments, the clickable link may be highlighted, underlined, rendered in a contrasting text color (i.e., blue text), or any other means to distinguish the clickable link from surrounding content within the image. In one embodiment, URL program 110 utilizes a client-side component on a client device, such as client device 106 and client device 108, to present the metadata for a URL as a clickable link within an image screen being shared during a live collaborative web meeting session.
