This disclosure relates generally to distance learning and, more particularly, to methods and systems for teaching a practical skill to students, employees, or other learners at geographically separate locations.
Non-limiting and non-exhaustive embodiments of the disclosure are described with reference to the Figures, in which:
The embodiments of the disclosure will be best understood by reference to the Figures, wherein like elements are designated by like numerals throughout. In the following description, numerous specific details are provided for a thorough understanding of the embodiments described herein. However, an artisan will recognize that one or more of the specific details may be omitted, or other methods, components, or materials may be used.
Furthermore, the described features, operations, or characteristics may be combined in any suitable manner in one or more embodiments. It will also be readily understood that the order of the steps or actions of the methods described in connection with the embodiments disclosed may be changed as would be apparent to those skilled in the art. Thus, any order expressed in the Figures or Detailed Description is for illustrative purposes only and is not meant to imply a required order, unless specified to require an order.
Embodiments may include various steps, which may be embodied in machine-executable instructions to be executed by a general-purpose or special-purpose computer (or other electronic device). Alternatively, the steps may be performed by hardware components that include specific logic for performing the steps or by a combination of hardware, software, and/or firmware.
Several aspects of the embodiments described will be illustrated as software modules or components. As used herein, a software module or component may include any type of computer instruction or computer executable code located within a memory device and/or transmitted as electronic signals over a system bus or wired or wireless network. A software module may, for instance, comprise one or more physical or logical blocks of computer instructions, which may be organized as a routine, program, object, component, data structure, etc., that performs one or more tasks or implements particular abstract data types.
In certain embodiments, a particular software module may comprise disparate instructions stored in different locations of a memory device, which together implement the described functionality of the module. Indeed, a module may comprise a single instruction or many instructions, and may be distributed over several different code segments, among different programs, and across several memory devices. Some embodiments may be practiced in a distributed computing environment where tasks are performed by a remote processing device linked through a communications network. In a distributed computing environment, software modules may be located in local and/or remote memory storage devices.
An artisan will recognize, however, that the methods and systems disclosed herein may be used for teaching other practical skills to one or more learners, non-exhaustive examples of which include carpentry, automotive repair, graphic design, culinary arts, plumbing, fashion design, and the like. Thus, the examples herein relating to cosmetology should not be considered limiting, but merely illustrative, of applications of the claimed systems and methods.
In one embodiment, each learner may be given (or have access to) a network-enabled computing device, referred to herein as a learner system 100. A learner system 100 may be embodied, for instance, as a desktop or laptop computer, although other network-enabled computing devices, such as interactive television (iTV) systems, personal digital assistants (PDAs), or the like, may be used.
In one embodiment, a teacher of the practical skill may also be provided (or have access to) a network-enabled computing device, referred to herein as a teacher system 102. The teacher system 102 may also be embodied as a desktop or laptop computer, iTV system, PDA, or the like, may be located, for example, at a technical school, a cosmetology school, a hair salon, the teacher's home, or other suitable locations at which it is convenient for the teacher to work.
The learner and teacher systems 100, 102 may each be equipped with a camera 104, such as a webcam. Various webcams are known in the art, such as a Logitech® QuickCam®. In other embodiments, however, one or more of the learner systems 100 and/or the teacher system 102 may be connected to a portable video camera, such as a Panasonic® PV-GS180 or the like. Each camera 104 may be connected to its respective learner or teacher system 100, 102 via USB (Universal Serial Bus), Firewire®, or other standard interfaces. In one embodiment, the cameras 104 may be configured to capture motion video and/or still images, referred to hereafter as video feeds 108.
In one embodiment, each camera 104 may be oriented on a subject 110 on which a learner is to practice and/or demonstrate the practical skill. Although not illustrated, each camera 104 may also be oriented to at least partially capture the learner within its field of view. This may allow the teacher to periodically monitor the learner to ensure that he or she is on task.
The subject 110 may be placed on a rotatable base 112 to allow different sides of the subject 110 to be rotated into the field of view of the camera 104. In certain embodiments, the rotatable base may tilt to more easily show the top or bottom areas of the subject 110. For instance, the rotatable base may be coupled to a hinge, a rotor, or the like with an appropriate tensioning or locking mechanism to hold rotatable base at a desired angle.
In an alternative embodiment, the subject 110 may be stationary, and the camera 104 may be configured to move, pan, tilt, or zoom to view or focus on different portions of the subject 110. In still other embodiments, multiple cameras 104 may provide different views of the subject 110.
As will be discussed in greater detail below, the teacher system 102 may also include one or a plurality of cameras 104 for capturing demonstration video feeds 108 for distribution in a live or recorded format to one or more learners. For example, in one embodiment, the learners may watch the teacher perform the practical skill in the demonstration video feed 108, after which the learners will attempt to imitate the skill on their respective subjects 110. As in the case of the learner video camera(s) 104, the teacher video camera(s) 104 may be fixed or movable, and may be capable of panning, tilting, and/or zooming.
As illustrated, the subject 110 may be embodied as a mannequin head for use in cosmetology instruction. In other embodiments, however, the subject 110 may be an automotive engine, a carpenter's work piece, or the like, depending on the practical skill being taught.
In one embodiment, the video feeds 108 originating from each learner system 100 are transmitted over a network 116, such as a LAN, WAN, the Internet, etc., to the teacher system 102 to be simultaneously displayed on an associated display screen 118. In some cases, only a subset of the video feeds 108 (e.g., two or more) may be simultaneously displayed. In such an embodiment, different video feeds 108 may be displayed in the same location of the display screen 118 in an automatically rotating cycle, such that all of the video feeds 108 will be eventually displayed (although not all at the same time).
The display screen 118 may be embodied as a television screen, computer monitor, or the like, which may be large enough to display each of the video feeds 108 in a reduced-size format. For instance, the display screen 118 could be embodied as a wide-screen high-definition television (HDTV) monitor or the like.
In certain embodiments, multiple display screens 118 may be provided for different types of information. For example, one display screen 118 may be devoted to displaying the video feed 108 for one particular learner, while another display screen 118 may be used to display the rotating cycle of video feeds 108 discussed above. Yet another display screen could provide interfaces for communicating with learners. Of course, all of the foregoing could be implemented in different areas of the same display screen 118 in one embodiment.
In one embodiment, the instructor may selectively enlarge one or more of the reduced-size video feeds 108 to display the full-resolution output of the respective camera(s) 104. The selected video feed(s) 108 may be enlarged to fill all or some defined portion of the display screen 118, as illustrated in
One or more learners may submit text or audio questions (or comments) 120 over the network 116 to the teacher that are not immediately conveyed to the other learners. As used herein, the term “question” may include any feedback provided by a learner, including comments or the like. Still or moving images (“instant replays”) taken by the camera 104 may accompany a question 120, for instance, to allow the teacher to see actually what was being captured by the learner's camera 104 at the time of the question 120. This may allow the teacher to better understand the context of the question 120 and/or allow the learner to bring specific issues to the teacher's attention.
As described in greater detail below, the teacher may select one of the learners submitting a question for individualized instruction, after which a private communication channel 126 may be established between the teacher and the selected learner. The selection may be made, in one embodiment, by highlighting, pointing to, or otherwise selecting one of the reduced-size video feeds 108 on the display screen 118. Alternatively, the selection may be made in response to the teacher selecting a question 120 from one of the interfaces illustrated in
As noted above, the teacher system 102 may include a camera 104 for capturing demonstration video feeds 108 (including still images) for distribution to one or more learners. A microphone 136 and/or speaker 138 may also be included with the teacher system 102, which may be incorporated in a single device, such as a headset 134 (
Within the teacher system 102, various components, implemented as hardware, software, and/or firmware, may carry out the methods disclosed herein. Similar components may be included within each learner system 102 and, to avoid repetition, will not be discussed in detail here.
In one embodiment, the teacher system 102 may include a network interface 142 for communicating with the learner system 100 over the network 116. The teacher system 102 may also include a video receiver 146, in electrical connection with the network interface 142, for receiving the video feeds 108 generated by the cameras 104 at each learner's location. The video receiver 146 may additionally receive captured video and still images from the teacher's camera 104. Included with the video receiver 146 or as a separate component, a video transmitter 148 may allow the teacher to send video feeds 108 captured at the teacher system 102 or elsewhere to one or more of the learner systems 100.
In one embodiment, a video processor 150 in communication with the video receiver 146 processes the received video feeds 108 for simultaneous display. The video processor may include or be in electrical communication with circuitry for rendering the video feeds 108 on the display screen 118.
As described in greater detail below, a video annotator 154 may enable a teacher to add graphics and/or text to video feeds 108 before storage or transmission. This may be accomplished with a mouse, pointer, keyboard, or other input device (not shown), which facilitates annotation of the video feed. Video annotation will be discussed in detail with reference to
An audio receiver 156 and audio transmitter 158, in communication with the network interface 142, may receive and transmit audio, respectively. An audio processor 160 electrically communicates with the audio receiver and audio transmitter 156, 158 to process audio as captured by the microphone 136 and to be played by the one or more speaker 138 to enable audio communication between the teacher system 102 and one or more selected learner system 100.
A storage device 164, such as a hard disk drive, flash memory, random access memory, or the like, may also be included with the teacher system 102 to provide storage for the video feeds 108, and annotated versions thereof, audio messages, text messages, stored media, application programs, and the like. In one embodiment, a CPU 166 controls the operation of the foregoing components to implement the methods described hereafter.
In alternative embodiment, the teacher system 102 is not responsible for reception and distribution of all of the video feeds 108, managing communications with the learner systems 100, and the like. Rather, the teacher system 102 and the learner systems 100 may all access a centralized video server (not shown), which includes components similar to those discussed with reference to the teacher system 102. In such an embodiment, video server may receive all of the video feeds 108 from the learner systems 100 and send the teacher system 102 a composite video feed 108 comprising all of the individual video feeds. Furthermore, any demonstration video feeds 108 captured at the teacher system 102 may be sent to the video server for distribution to one or more learner systems 100. Additionally, the video server may handle all text and audio communication between the teacher system 102 and the learner systems 100. Thus, the teacher system 102 may, for most purposes, be similar or identical to the learner systems 100.
The teacher text messaging interface 300 may further include a teacher text response window 310 and/or an audio link initiator 312 that allow the teacher to respond to a learner selected from among those having questions 120 in the message queue 302. In one embodiment, “double clicking” on one of the learners listed in the message queue 302 results in the learner being “selected.”
The teacher text messaging interface 300 automatically includes the selected learner (Aaron Becker, in this example) as the recipient, and gives the teacher the option of adding additional learners. If additional learners are added, the communication becomes non-private. The question (and response) may, therefore, be broadcast to other learners to allow them to benefit from a question/answer session between the teacher and the selected learner. The audio link initiator 312 allows the teacher to respond with a personal audio communication to the selected learner, and likewise includes the ability to add additional learners to make the responsive audio communication non-private. Audio communication may be through a public switched telephone network (PSTN), leased lines, wireless networks, or over the Internet using the Voice over IP (VoIP) protocol.
The storage device 164 may be used for storing the learners e-mail addresses, phone numbers, or other indicators for sending text-based messages or for initiating audio communication. For instance, the teacher may type part of the name of a learner in the “Add Recipient” box 314 of the teacher text response window 310 to bring up the text messaging address of the learner to be added. Furthermore, the teacher may type part of the name of a learner in the “Add Learner” box 316 of the audio link initiator 312 to bring up the audio link (or phone) number of the learner to be contacted. In the alternative, the learner's contact address or numbers may be typed in directly, browsed for in a directory, etc. Alternatively, additional recipients may be selected by simply clicking on or touching a video feed 108 of a learner on the display screen 118. In certain embodiments, a teacher may be able to select all of the learners by activating a “select all” button or the like (not shown).
In one embodiment, learners have the option of attaching a file to the text message by clicking on the “Attach File” 326 link. Such a file may include any number of demonstrative or data files, for instance a report, an image, a video clip, or an audio message, all of which are previously stored on the learner system 100. In other embodiments, an mechanism such as an on-screen button (not shown) may be provided to allow a learner to immediately capture a still image or video “instant replay” to attach to a text message.
In one embodiment, the audio link initiator 312 includes an “Add Learner” box 316 for adding additional learners, as discussed in
Additionally, the teacher system 102 allows the teacher to transmit an annotated demonstration video feed 608 to one or more learners by adding an annotation 610 to the demonstration video feed 108 before transmission.
In this example, a cosmetologist 702 is demonstrating the proper way to greet a client 704 and direct the client 704 to one of the available salon chairs 706. In one embodiment, the demonstration video feed 108 is sent over the network 116 to the teacher system 102 where the teacher has the option to selectively transmit the video feed 108 to one or more of the learners. In other embodiments, the demonstration video feed 108 could be sent directly to a plurality of learner systems 100 without passing through the teacher system 102.
The teacher may optionally transmit an annotated demonstration video feed 708 to one or more learners by adding an annotation 710 to the demonstration video feed 108 before transmission to enrich the instruction of the learner(s). The teacher may also add audible and/or textual commentary to the demonstration feed 108 or 708 before transmission to point out, for instance, good and bad techniques, etc. The demonstration feeds 108, the annotated demonstration video feeds 608, 708 and the annotated learner-submitted video feeds 508 may be stored by the teacher in the storage device 164 of the teacher system 102.
In addition to distributing to one or more learners a media file, the teacher may also use the interface 800 to add a text or an audio commentary. In the teacher text response window 310, the teacher may write to one or more learner recipients a commentary regarding the distributed video clip or still image. In the “Add Recipient” box 314, the teacher may enter additional learners to which the teacher wants to send the video clip or still image file. The “Attach File” link 826 allows the teacher to add an audio commentary, such as a saved voice message, if the teacher desires.
The method 900 further allows 906 the learners to submit questions to the teacher, either textually or via audio. The teacher may subsequently be allowed 908 to select a learner from those who have submitted questions for individualized instruction. The teacher may then be allowed 910 to establish a private communication channel with the selected learner in order to provide the individualized instruction.
While specific embodiments and applications of the disclosure have been illustrated and described, it is to be understood that the disclosure is not limited to the precise configuration and components disclosed herein. Various modifications, changes, and variations apparent to those of skill in the art may be made in the arrangement, operation, and details of the methods and systems of the disclosure without departing from the spirit and scope of the disclosure.
