|A Hands On Tour|
We typically introduce the Lecture123 system in a face-to-face meeting where we can present an overview along with demonstrations highlighting key features. If you are reading this page, then you might have seen this talk and want to revisit some areas of interest or perhaps you've not yet met with us, but would like to take your own self guided tour. The trek below can be done in as little as 20 minutes, but like any journey you can slow down, take your time, and focus as you see fit. The key is for you to have fun and get some exposure to our project.
You may wish to review our extensive User Manual.
Lecture123 supports many different repositories, e.g. each corporation or school might have their own repository. Each of these repositories have their own lecture storage area along with separate Lecture123 programs. This hands-on tour uses the general Lecture123 repository. You will be guided to register for user account, install Lecture123 programs, and play and record content from this Lecture123 repository. If you use another repository, then once you complete this tour you will need to register and install the programs from that repository -- then you are ready to work in your area.
Before you hit the trail, you must first install Lecture123. This is usually accomplished in 5 minutes if you have a fast network connection (dialups will take longer to download the install program).
In order to view the lectures below or record and publish your own lectures you must first register for a free login account in the Demo community here. The community key is demo
There's more information about login accounts and communities here.
We find that a good place to start is to playback the following four lectures on the Lecture Playback web page. When you click on the lecture name below Java Web Start will launch the LecturePlayer application and then open up that lecture making it ready for playback. Once you see the thumbnails of the slides on the left you just need to click the Play button and the lecture playback begins. You can Pause the lecture, click any thumbnail to skip to that portion, or slide the slidebar on the bottom.
Now it's time to try the to record a lecture session. Click Presenter to start the tool that will get your lecture ready for presentation, allows you to present the lecture, and records your pen strokes, voice, and slide navigations. There are two type of lectures. You specify the type by clicking the Start button.
Once you hear a beep sound the lecture is being recorded. It's best if you have a PC with a microphone (you'll know it's working by the little VU meter near the top of the Presenter window). Once the Presenter is loaded feel free to scribble with your mouse (or pen if you are using a tablet) and play with the pen and highlighter colors/widths. When you are done click the STOP Lecture button and the system will enter the publishing step. This allows you to upload the recorded session to the Lecture123 server so it can be played back over the Internet. Select the Demo community and the folder where it should be published to (for now publish the lecture to the demo folder). Then enter the lecture name and the email address that should be used to notify you as the owner of this lecture when any questions are asked during playback. The recorded files are zipped together, uploaded to the server, and are now available for playback.
Let's playback this lecture by visiting the Lecture Playback page and clicking on the name of the lecture you just published. Notice how the voice, pen annotations, and slide navigations all play back fully synchronized exactly as they were presented. Navigate around the lecture with the thumbnails, slidebar, or the Prev and Next buttons.
You are ready to try the QA feature. While playing your lecture simply right click the mouse and select Ask A Question..., type in your question and submit it. Email will be sent to the email address you used when you published the lecture in the Presenter (and to you as the student, so you'll likely get 2 emails since you are now wearing 2 hats). In the instructor email you get you will see a URL at the bottom of the body; click that URL and your slide along with all the question details will be loaded into your web browser. Notice that the location where you clicked is highlighted by a QA spot on the slide. You may now answer the question by typing in your response. This automatically integates your response back into the lecture. The next time someone plays this lecture the question and answer are included in the lecture. Let's reload this lecture in the LecturePlayer with File>Reload and you will see a QA marker appear at the time and location where you posted the question (use the slidebar to get to the time where you posted that question). The QA marker appears at the exact time and location where you posted the question. Click on that marker to get to the QA window to see the QA details.
Finally, all content published in the knowledge repository is searchable. This includes text on slides and in any question or answer exchange. Simply click on Search in the blue toolbar once you are logged in with your web browser. Now select the scope of the search and enter the text you wish to find. The results page will list all the lectures where matches have been found. You can do a quick review of the slide or QA in the browser or launch the player to directly index to the place and time where that match occured in the lecture.
This journey has taken you through some the core feature set (there are other pieces to QAs, e.g. searching; and of course we have long list of upcoming enhancements). We'd certainly like to get your feedback via email. We hope this has been fun and informative.
