20150121231
Presentation systems generally enable a user to create a presentation using a slide presentation software package and display the presentation (e.g., as a slideshow) as series of pre-set (e.g., static) slides to one or more viewers or participants. While such presentation systems may be useful, the presenter may desire a more dynamic way to display the presentation such as pushing different parts of the information out to subgroups of viewers.
Various embodiments of the present systems and methods recognize and address the foregoing considerations, and others, of prior art systems and methods.
In an embodiment, the invention is directed to a computer-implemented method of presenting information to at least two groups of viewers. Each viewer in the two groups of viewers is using a mobile computing device. The method includes one or more of the steps of (1) receiving a selection by a user of a slide presentation that the user wishes to present to the two groups of viewers, where the slide presentation includes one or more slides; (2) generating a code that is associated with either the user or the slide presentation; (3) facilitating presentation of the code and the slide presentation to the two groups of viewers (e.g., displaying the slides on an interactive display such as an interactive whiteboard); (4) receiving the code and an identifier that is unique to each mobile computing device associated with each viewer; (5) generating a session code for the presentation of the slides; (6) displaying the slides on at least one interactive display; and (7) during the presentation of the slides, distributing first electronic information to a first group of viewers using the first session code and a group identifier, and second electronic information to a second group of viewers using the session code and second group identifier.
In various embodiments the first and second electronic information may each be one particular electronically editable version of a slide in the slide presentation. In other embodiments, the first electronic information may be an electronically editable version of a first particular slide and the second electronic information may be an electronically editable version of a second particular slide. The first and second particular slides may each be a respective version of slides that are displayed to the viewers during the presentation, or they may be slides that contain subject matter that relates to the subject matter in the slide presentation, but the slides are not necessarily displayed on the interactive display during the presentation.
In some embodiments, the viewer can edit the electronically editable version of the slide during the presentation by using a mobile device assigned to the viewer and send the edited version of the slide back to the user. The viewer may send the edited version of the slide back during the presentation, or in various embodiments, the viewer may send the edited version of the slide back to the user after the presentation is completed.
A full and enabling disclosure of the present invention, including the best mode thereof directed to one of ordinary skill in the art, is set forth in this specification, which makes reference to the appended drawings, in which:
Reference will now be made in detail to presently preferred embodiments of the invention, one or more examples of which are illustrated in the accompanying drawings. Each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that modifications and variations can be made to the present invention without departing from the scope or spirit thereof. For instance, features illustrated or described as part of one embodiment may be used in another embodiment to yield a still further embodiment. Thus, the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.
In one particular embodiment, the presentation system runs one or more modules that provide an interactive classroom (e.g., teaching/learning) experience. The modules(s) may include, but is not limited to: 1) a lesson building module that a user (e.g., a third party slide presentation creator, the teacher, etc.) uses to create a slide presentation (e.g., a lesson); 2) a presentation module that the teacher uses to display/present the slide presentation; and 3) a learner module that, in a particular embodiment, runs on the mobile computing device that is used by a student to view and/or interact with the slide presentation. In various embodiments, each of the modules may be web-browser based.
In various embodiments, when the teacher sets up a class/classroom for the first time on the presentation system, the teacher logs into the presentation system using a presentation device (e.g., a computer connected to an interactive device), and enters data about the class/classroom and/or the students, and the presentation system assigns an identification number (e.g., a class code) for the particular class being taught by the teacher. The class ID may be a fixed code that is assigned to the class for the duration of the class (e.g., a school year, a semester, etc.). Thus, when the teacher is ready to present a particular lesson to the class, the teacher signs into their account on the presentation system using the presentation device and selects the class and the particular slide presentation to present. Once the teacher selects the class and slide presentation, the presentation system provides the class ID (e.g., the class code) to the presentation device, which displays the class ID on the interactive display. Each time the teacher selects a slide presentation and a class in which to present the slide presentation, the unique class ID is displayed on the interactive display for the selected class. For example, if a teacher presents a new slide presentation to the same class each day (e.g., a teacher teaches new material in a math class every day to the same students), each of the slide presentations for each day shares the same class ID as long as the teacher is presenting to the same class.
Additionally, each time a teacher selects a class and a presentation to present, the presentation system establishes a session (e.g., an instance in time when a teacher is presenting a slide presentation to a class). Each session is assigned a session ID by the presentation system, which allows each computing component (e.g., the presentation device, the student's mobile computing devices, a presentation controller and a host server) in the presentation system to communicate with one another during the session. Thus, when students log into the presentation system on their mobile computing device using the class ID and information that identifies the student (e.g., the student's name, device identification information, student ID, etc.), their mobile computing devices communicate with the presentation system using the session code. The session ID stays active until the teacher closes the session (e.g., logs out of the system, ends the slide presentation, selects a new class, etc.).
The presentation system may also be configured to allow a teacher to distribute electronically editable slides using the session ID. For example, a teacher may send an electronically editable version of a particular slide of the slide presentation to one or more students viewing the presentation. The students receive the electronically editable version of the slide on their mobile computing device and can edit or manipulate objects in the slide, or respond to questions presented on the slide using the mobile computing device. Once the students complete a requested task associated with the electronically editable version of the slide, the presentation system is configured to receive edited versions of the electronically editable slides from the students' mobile computing device.
The presentation system may also be configured to allow the teacher to create groups of students by using the session ID. In various embodiments, the presentation system appends a group identifier to the end of the session ID for each group created on the system. The presentation system may automatically determine groups based on one or more student attributes (e.g., learning abilities, prior test scores, grade point averages, answers to questions asked during the presentation, etc.), or the teacher may manually set up the groups either when the slide presentation is created or during the presentation of the slide presentation. Creating groups may allow the teacher to transmit (e.g., push) different electronic material (e.g., electronically editable slides, electronically editable tests, etc.) to each group of students.
While the above example is directed to use of the presentation system in a classroom setting, the presentation system may also be used in a business setting (e.g., during a company presentation, seminar, workshop, etc.). In business environments, instead of the code being associated with a class, each unique code is associated with the presentation. Otherwise, the system generally operates similar to the discussion above.
As will be appreciated by one skilled in the relevant field, the present systems and methods may be, for example, embodied as a computer system, a method, or a computer program product. Accordingly, various embodiments may be entirely hardware or a combination of hardware and software. Furthermore, particular embodiments may take the form of a computer program product stored on a computer-readable storage medium having computer-readable instructions (e.g., software) embodied in the storage medium. Various embodiments may also take the form of web-implemented computer software. Any suitable computer-readable storage medium may be utilized including, for example, hard disks, compact disks, DVDs, optical storage devices, and/or magnetic storage devices.
Various embodiments are described below with reference to block diagram and flowchart illustrations of methods, apparatuses (e.g., systems), and computer program products. It should be understood that each block of the block diagrams and flowchart illustrations, and combinations of blocks in the block diagrams and flowchart illustrations, respectively, can be implemented by a computer executing computer program instructions. These computer program instructions may be loaded onto a general purpose computer, a special purpose computer, or other programmable data processing apparatus to produce a machine. As such, the instructions which execute on the general purpose computer, special purpose computer, or other programmable data processing apparatus can direct a computer or other programmable data processing apparatus to function in a particular manner such that the instructions stored in the computer-readable memory produce an article of manufacture that is configured for implementing the functions specified in the flowchart block or blocks.
The program code may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer, or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including: a local area network (LAN); a wide area network (WAN); a cellular network; or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider).
These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner such that the instructions stored in the computer-readable memory produce an article of manufacture that is configured for implementing the function specified in the flowchart block or blocks. The computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions that execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart block or blocks.
The one or more networks 55 may include any of a variety of types of wired or wireless computer networks such as the Internet, a private intranet, a mesh network, a public switch telephone network (PSTN), or any other type of network (e.g., a network that uses Bluetooth or near field communications to facilitate communication between computers). The one or more networks 55 may be a local area network (LAN), a wide area network (WAN), a cellular network, and/or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In particular embodiments, the one or more networks 55, together with the host server 65, the session server 40, and the collaboration server 45, facilitate communication between the presentation device 15, mobile computing devices 30, the presentation controller 35, the one or more third party servers 50, and/or the host server 65, as described in more detail herein.
The presentation device 15 is operatively connected to the interactive display 20 by a universal serial bus (USB).

In a particular embodiment, the interactive display 20 is an interactive whiteboard that is touch and/or pen input enabled, such as those produced by Promethean World Plc (Promethean, Ltd.). An example of an interactive whiteboard is described in U.S. Pat. No. 8,325,162 to Promethean Ltd., which is incorporated by reference herein in its entirety. It should be understood, in light of this disclosure, that the interactive display 20, in one or more embodiments, is an interactive display other than a whiteboard, such as a computer monitor, which may or may not be touch-enabled, a touch screen computer, an interactive table display, a projector with a screen having one or more input sensor (e.g., a light curtain), a television operatively connected to one or more motion sensing devices, etc. In particular embodiments, the presentation device 15 may be omitted and the interactive display 20 (e.g., an interactive whiteboard, smart TV, or other suitable display) may perform the functions carried out by the presentation device 15.
One or more input devices 25 are operatively coupled to the interactive display 20 by a wireless connection 60. In various embodiments, the input devices 25 may be wirelessly connected to the presentation device 15, or through any other network connection to various other components in the presentation system 10. The input devices 25 are configured to receive input from viewers of a presentation and transmit the input to the interactive display 20. One example of an input device 25 is an ActivExpression™ or ActiVote™ device manufactured by Promethean World Plc (Promethean Ltd.).
In particular embodiments, the host server 65 may be connected (e.g., networked) to one or more other computers via a LAN, an intranet, an extranet, and/or the Internet (e.g., one or more networks 55). As noted above, the host server 65 may operate in the capacity of a client computer in a client-server network environment, and/or as a peer computer in a peer-to-peer (or distributed) network environment. The host server 65 may be a desktop personal computer (PC), a tablet PC, a set-top box (STB), a Personal Digital Assistant (PDA), a cellular telephone, a web appliance, smart TV, an interactive whiteboard, a server, a network router, a switch or bridge, or any other computer capable of executing a set of instructions (sequential or otherwise) that specify actions to be taken by that computer. Further, while only a single computer is illustrated, the term “computer” should also be understood to include any collection of computers that individually or jointly execute a set (or multiple sets) of instructions to perform any one or more of the methodologies discussed herein.
An exemplary host server 65 includes a processor 202, a main memory 204 (e.g., read-only memory (ROM), flash memory, dynamic random access memory (DRAM) such as synchronous DRAM (SDRAM) or Rambus DRAM (RDRAM), etc.), a static memory 206 (e.g., flash memory, static random access memory (SRAM), etc.), and a data storage device 218, which communicate with each other via a bus 232. The host server 65 may further include a network interface device 208, a video display unit 210 (e.g., a liquid crystal display (LCD) or a cathode ray tube (CRT)), an alphanumeric input device 212 (e.g., a keyboard), a cursor control device 214 (e.g., a mouse), and a signal generation device 216 (e.g., a speaker)).
The processor 202 represents one or more general-purpose processors such as a microprocessor, a central processing unit, or the like. More particularly, the processor 202 may be a complex instruction set computing (CISC) microprocessor, reduced instruction set computing (RISC) microprocessor, very long instruction word (VLIW) microprocessor, or processor implementing other instruction sets, or processors implementing a combination of instruction sets. The processor 202 may also be one or more special-purpose processors such as an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), a digital signal processor (DSP), network processor, or the like. The processor 202 may be configured to execute processing logic 226 for performing various operations and steps discussed herein.
The data storage device 218 may include a machine-accessible storage medium 230 (also known as a non-transitory computer-readable storage medium or a non-transitory computer-readable medium) on which is stored one or more sets of instructions (e.g., software 222) embodying any one or more of the methodologies or functions described herein. The software 222 may also reside, completely or at least partially, within the main memory 204 and/or within the processor 202 during execution thereof by the host server 65—the main memory 204 and the processor 202 also constituting computer-accessible storage media. The software 222 may further be transmitted or received over the network 55 via a network interface device 208.
The software 222 may represent any number of program modules, including, but not limited to an operating system (not shown), a presentation builder module (not shown), a learner module (not shown), the presentation module 300 (see
While the machine-accessible storage medium 230 is shown in an exemplary embodiment to be a single medium, the term “computer-accessible storage medium” should be understood to include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) that store the one or more sets of instructions. The term “computer-accessible storage medium” should also be understood to include any medium (transitory of non-transitory) that is capable of storing, encoding or carrying a set of instructions for execution by the computer and that cause the computer to perform any one or more of the methodologies of the present system. The term “computer-accessible storage medium” should accordingly be understood to include, but not be limited to, solid-state memories, optical and magnetic media, etc.
The system of
At step 320, the host server 65 generates a code that is associated with either the user or the selected slide presentation. In preferred embodiments where the slide presentation is a lesson given to students of a class, the user is a teacher, the viewers are students, and the code is associated with the particular class that the teacher is teaching. In these embodiments, the code may be valid for the duration of the class (e.g., semester, trimester, school year, etc.). In other embodiments where the selected slide presentation is a presentation that is given by a business person to a group of colleagues, the code may be associated with the presentation, which remains valid until the presentation is deleted from the system. In these embodiments, if a copy of the presentation is generated by the system, a new code is generated by the host server 65 and assigned to the copy of the presentation. In still other embodiments, the code may be associated with the user presenting the presentation. That is, the code is generated by the host server 65 and assigned to the user's account so that each time the user is presenting a presentation, the user's code is displayed by the system.
At step 330, the host server 65 facilitates presentation of the code and the slide presentation to the at viewers. In a preferred embodiment, the host server 65 facilitates display of the code prior to the presentation of the one or more slides. In other embodiments, the system may display the code substantially simultaneously with display of the slide presentation. That is, in these embodiments, the introduction slide may be displayed substantially simultaneously with the code. In a preferred embodiment, facilitating presentation of the code and the slide presentation further comprises displaying the code and the one or more slides on the interactive display 20. In this embodiment, the interactive display 20 is an interactive whiteboard and the code and the presentation are projected onto the interactive whiteboard. In other embodiments, the interactive display may be a touch monitor, a tablet, an interactive television, or any other suitable interactive display connected to an interactive device such as a mouse, a light curtain, a pen input, or a gesture input device (e.g., a Kinect™ controller).
In a particular embodiment, each of the viewers of the presentation has a mobile computing device (e.g., a tablet, a smart phone, etc.) associated with the viewer. Using the mobile computing device, the viewer can download an application program that will allow them to enter the code and communicate with the host server 65. Once the viewer enters the code, at step 340, the host server 65 receives both the code and a unique identifier associated with the mobile computing device. In various embodiments, the unique identifier may comprise a Media Access Control Address (MAC address) of the mobile computing device or some other identifier specific to the mobile computing device (e.g., the device UDID, the device serial number, etc.). In other embodiments, the unique identifier may also contain information specific to the viewer (e.g., one or more of the viewer's name, student ID, employee ID, or any other suitable ID associated with the viewer).
At step 350, the host server 65, in combination with the session server 40, generates a session code that is unique to the presentation of the slide presentation. The session code is associated with a session (e.g., a period of time when a slide presentation is being presented, a class, etc.). Thus, a session is an abstraction of time when the various computing devices for a presentation (e.g., presentation device 15, presentation controller 35, mobile computing devices 30 and the host server 65) interact with each other. In various embodiments, each session may be unique and represented by a session code that is valid for a specific duration. In one or more embodiments, the duration of a session may last from a few minutes to several weeks or months. For example, a session may be established for a short period of time (e.g., minutes) to distribute homework, and in other embodiments, the session may last for an hour (e.g., the length of a classroom period). In various embodiments, the session server 40 manages the various computing devices associated with a presentation during the session. In various embodiments, the session server 40 provides application program interfaces for one or more of the various computing devices to start a session, stop a session, join a session, disconnect a session, pause a session and terminate a session. In a preferred embodiment, each of the various computing devices communicates with one another using the session code.
At step 360, the host server 65, in combination with the session server 40 and the collaboration server 45, displays the one or more slides on the interactive display 20. In various embodiments, the session server 40 works together with the collaboration server 45 to broadcast the presentation from the host server 65 to one or more of the presentation device 15, the presentation controller 35, and the mobile computing devices 30. In various embodiments, viewers may be located in the same room as the interactive display 20 or they may be located anywhere in the world so long as they are connected via the one or more network 55 (e.g., the Internet).
During the presentation of the one or more slides, at step 370, the host server 65, in combination with the session server 40 and the collaboration server 45, distributes (1) first electronic information to a first group of viewers using the session code and a first group identifier, and (2) second electronic information to a second group of viewers using the session code and second group identifier. In a particular embodiment, the host server 65, in combination with the session server 40, distinguishes between the first group of viewers and the second group of viewers by appending the first group identifier to the session code for the first group and appending the second group identifier to the session code for the second group. In this way, the first electronic information can be addressed to one or more specific mobile computer devices for viewers in the first group, and the second electronic information can be addressed to one or more specific mobile computing devices of viewers in the second group.
In various embodiments, viewers may be selected for the first and second group either automatically by the host server 65 based on various information and criteria. For example, in embodiments where the user is a teacher, the presentation is a lesson and the viewers are students, the viewers may be automatically selected to be in a group based on one or more of (1) at least one response to a question asked during presentation of the one or more slides, (2) random selection, (3) the viewer's grade point average, (4) the viewer's style of learning, (5) the viewer's primary language, (6) the viewer's prior test results, and (7) information from social networks. In particular embodiments, the host server 65 may be configured to receive information from one or more third party servers that store one or more of the above listed criterion.
In some embodiments, the host server 65 may be configured to receive information from social networks regarding viewers. Thus, in embodiments where the slide presentation is presented in a business setting (e.g., a conference, seminar or workshop), the host server 65 may prevent viewers that are connected on a social networking sites or that work together from being placed in the same group of viewers to encourage networking between viewers that have no known previous relationship.
In some of the above embodiments, viewers may also be manually placed into groups by the user. Thus, in the classroom example, the teacher may prospectively group students when the teacher is creating the slide presentation. For example, in some of these embodiments, the teacher may group the students based on personal knowledge of the student's abilities. For example, some students may be advanced, some students may be slower at learning new material and for other students, English may be their second language. As a result, each group of students may be formed manually by the teacher prior to presenting the slide presentation by using, for example, the presentation device 15 or the presentation controller 35. In other embodiments, the teacher may manually assign students to groups during presentation of the slide presentation. In these embodiments, the teacher may select students indirectly on the presentation device 15 using the interactive display 20 or directly using the presentation controller 35.
During the presentation of the one or more slides and after distributing the first and second electronic information, at step 380, the host server 65, in combination with the session server 40 and the collaboration server 45, is configured to receive an edited version of the first and second electronic information from each viewer in the first and second group. In various embodiments, the mobile computing devices 30 are configured to send the edited version of the first and second electronic information to the host server 65. In other embodiments, the host server 65 is configured to poll the mobile computing devices 30 to pull the edited versions of the first and second electronic information from the mobile computing devices.
Also during presentation of the one or more slides and after receiving the edited versions of the first and second electronic information, the host server 65, at step 390, facilitates the display of at least one of the edited versions of the first and second electronic information. In a particular embodiment, the first and second electronic information are the same electronically editable version of one particular slide from the one or more slides of the presentation. In another preferred embodiment, the first electronic information is an electronically editable version of a first particular slide from the one or more slides and the second electronic information is an electronically editable version of a second particular slide from the one or more slides. In some of these embodiments, the one particular slide may be a slide that is displayed to the viewers and in other embodiments, it may be a slide that is part of the slide presentation but not necessarily a slide that is displayed to the viewers. For example, the slide presentation may contain one or more slides that are associated with slides that are displayed to the viewers. In these embodiments, these slides may contain one or more notes, questions, or test questions that cover the subject matter covered by the displayed slides, etc. Thus, while these slides are part of the presentation, they are slides that are configured to be distributed to the viewers on mobile computing devices 30 as electronically editable slides as opposed to being displayed to the viewers on the interactive display 20.
In particular embodiments where the first and second electronic information is an electronically editable version of one particular slide, host server 65, in combination with the session server 40 and the collaboration server 45 (1) receives edited versions of the one particular slide from the mobile computing devices 30 and (2) facilitates display of one or more of the edited versions on the interactive display 20. In other embodiments where the one particular slide is a slide that is being displayed on the interactive display 20, the host server 65, in combination with the session server 40 and the collaboration server 45, may be configured to receive the edits made by at least one of the viewers and to substantially simultaneously (e.g., simultaneously) display those edits on the one particular slide that is displayed on the interactive display 20 as the selected viewer makes the edits using their mobile computing device 30.
