On July 20 we had online
help available via WebChat.
The following information was provided to assist remote
participants with using the different technologies that were
available.
As you juggle the various technologies you may be using to access
the Mars
Virtual Teacher Training Conference, here are some ideas. Your best
bet is
to practice before the conference to see if these work in your
situation, and to possibly discover some even better ways to juggle.
We assume you have already installed a World Wide Web browser, RealAudio client, CU-SeeMe client, etc. If not, visit http://passporttoknowledge.com/marsconf/technology.html for links to the clients you can download for the conference.
For Web Users:
1) Be sure you have already familiarized yourself well with the Web
site at
2) On the day of the conference, as a Web user you will probably
spend most
of your time launching from
4) NOTE: There will be someone online all day July 20 for user help.
That
person can be contacted by going to the WebChat Discussion Room
and asking
for ONLINE HELP. **From 9:00 a.m. to 11:00 a.m. online help in that
room
will include a technical guru to help with particularly difficult
problems.
The technologies for the Virtual Conference are:
To ask a question that you would like answered during the Q & A
periods,
simply send your question to: mars-question@mail.arc.nasa.gov
Someone at the conference will receive your question and be
prepared to
ask it at the physical conference in Washington, DC. Just as at the
physical conference, time constraints may mean that not all
questions are
asked. However, remote questions will be given the same
consideration as
on-site questions.
To get an update of what is happening at the conference, join:
mars-update@quest.arc.nasa.gov
To join the list, send email to listmanager@quest.arc.nasa.gov and in
the
body of the message type only these words: subscribe mars-update
Suggested Uses:
If other technologies are not available to you, the updates will
provide a means for you to know what is happening at the workshop.
These updates will be sent every 15 minutes by teachers attending
the conference in DC who will summarize the proceedings.
Basic Trouble-shooting:
The subscription process is immediate. Within 30 minutes you
should receive a confirmation. On the day of the conference you
should receive an update every 15 minutes.
If you are having trouble subscribing, try turning off your signature
message, check for spelling errors and proper capitalization.
To read a copy of the WebChat discussion, point your browser to: http://passporttoknowledge.com/marsconf/discussion.html
Suggested Uses:
WebChat can be used in conjunction with RealAudio and Web site
graphic
updates. To use RealAudio, the Web site graphics, and WebChat all at
once, under the FILE menu at the top of your screen, select the NEW
BROWSER option. Point one of the windows to the Virtual
Conference
Pre-conference Chats and Test page at
The transcription of the proceedings can be used as the only way to
receive the conference information or it can be used in combination
with
RealAudio and Cu-SeeMe. The transcription will happen in the
Mars_Transcript room of the WebChat, and the Mars_Discussion room
will be
available for discussion among virtual participants, to post the
questions
you want asked at the Q & A in Washington, DC, and to get online
help.
The Web discussion will be active during the entire day from 9:00 to
5:00
Eastern. If you have a question for the speakers please make sure
that
the WebChat monitor is aware of your request, by addressing it with
these
words in all capitals: ATTENTION WEBCHAT MONITOR. If you need
online help
please type ONLINE HELP at the beginning of your request.
Mars_Transcript will be used for those who wish to receive a live
written
transcript of the proceedings as they are happening. You will be
barred
from posting in that room in order to avoid interruption of the
transcription. But don't worry if you make a mistake and post there.
Your
message will simply be ignored by the transcriber and will not show
up on
anyone's screen.
Basic Trouble-shooting:
Make sure you're in the room you mean to be in! Change rooms by
using the pull down menu (in most browsers) at the bottom of the
WebChat page for the room you're in.
If you are not getting the transcription or chat discussion
updates, remember to hit your
When sending a comment to the discussion WebChat, you are likely
to be interrupted if your browser has a place to set a refresh
rate. If you have set a refresh rate, be sure to hit the PAUSE
button at the top of your text entry window before you begin
typing your comment. When you are ready to send your message, hit
the CHAT button. Your message will be sent, and the automatic
refreshing will continue.
Suggested Uses:
This application can be used with the Web site and WebChat
discussion to
listen to the conference via the ongoing audio signal from NASA TV.
RealAudio produces and AM radio quality audio signal. You may be
able to
simultaneously join the WebChat discussion and view the
presentation
graphics.
To use RealAudio, the Web site graphics, and WebChat all at once,
under
the FILE menu at the top of your screen, select the NEW BROWSER
option.
Point one of the windows to the Virtual Conference Pre-conference
Chats
and Test page at
Note to host sites: In order to preserve the availability of audio
streams for other remote participants, please try to amplify the
audio
signal from one or two machines to all of your participants (rather
than
using one stream for each participant at a host site).
Basic Trouble-shooting:
Should you loose the RealAudio signal click on the player and try
hitting
the play button at the top left-hand corner of the player.
To adjust the volume, use the bar on the right of the RealAudio
Player
window. To stop receiving audio and disconnect from the audio
server, use
the STOP button at the top left of the window; to stop listening and
remain connected to the server, use the PAUSE button; and to play
again
after either of those actions, use the PLAY button.
If you are not getting a good connection, try closing down and
opening
RealAudio again. If it is still not good, try the backup RealAudio
server
from the Virtual Workshop Activities page. If you receive an error
message you don't understand, go to the Mars_Discussion Room in the
WebChat area and ask for ONLINE HELP.
To view the presentation graphics, point your web browser to: http://passporttoknowledge.com/marsconf/activity.html
Suggested Uses:
The Web site gives you periodic pictorial updates from the
auditorium and
the graphics that the presenters are using in their talks. As you
read
the WebChat transcription or listen to the RealAudio signal you will
be
able to view the graphics under discussion and see pictures of the
auditorium.
You might begin by opening a window for the graphics and loading the
first
presentation. Now is a good time to open another window in your Web
browser for the *second* presentation, and load in those graphics.
Then,
when the second presentation begins, you won't be scrambling to
catch up
because your browser took a long time to load. In order to keep
ahead of
yourself in this way through the whole day, try loading the graphics
for
the next presentation in a new window some time before the current
one
ends, or while Q & A is happening. If you try this twice and your
machine
freezes each time, abandon the idea!
There is a picture at the top of each set of presentation graphics
that
will be updated every minute or so. This is a shot of whatever is
happening in the NASA Headquarters auditorium at the time, and will
be
still shots fed from NASA TV. You may need to scroll a little to
begin the
presentation graphics.
In some cases, you may find the thumbnail pictures there enough for
you
to enjoy the presentation. In others, you may want to click to the
larger
image. To accommodate different browsers, the images are in jpeg and
gif
formats. If you're not sure which is best for you, try jpeg first.
REMINDER: You'll need to be paying attention in order know which
graphic
the presenter is speaking about. The only cue you'll have is the
presenter
him- or herself asking for the next slide. (You'll be receiving the
speaker's words via RealAudio, CU-SeeMe, or the Web site
transcription.)
You can go to the next set of graphics from a link at the top of each
presenter's page that says "Graphics for next presentation." The
"Continue" link at the bottom of each presenter's page will lead you
to
more slides by the same presenter, the next presenter's slides, or
back to
the agenda, as appropriate. You can also join the conference graphics
presentations at any time by locating the AGENDA section on the Web
site
and selecting the appropriate time slot.
Photos Taken by Teachers
There will also be pictures taken by teachers at the conference with
hand-held digital cameras. To look at these, you'll launch again from
the
LIVE CONFERENCE AREA Virtual Workshop Activities page at http://passporttoknowledge.com/marsconf/activity.html
Basic Trouble-shooting:
Remember that the cue to go to the next graphic will be verbally
spoken by
the presenter at the auditorium podium.
If you are not getting updated pictures from the auditorium,
remember to
hit the REFRESH or RELOAD button at the top of your browser screen.
If you are having difficulty that you cannot seem to resolve yourself,
go
to the the Mars_Discussion Room in the WebChat area and ask for
ONLINE
HELP.
The following technologies will be used to further propagate the
NASA TV
signal being generated in the NASA Headquarters Auditorium, which
is the
physical location of the conference. This signal will consist of the
speaker(s) on stage, associated graphics, and an occasional view of
the
auditorium audience.
Open your CU-SeeMe software, and connect to one of the following
reflector sites, then click on the conference in your Participant List
window.
Primary Reflectors:
Back-up Reflectors:
Suggested Uses:
Cu-SeeMe will send the NASA TV signal to participants. This
technology
can be used in combination with WebChat Discussions and Email to
interact
with the auditorium. Text-enhanced sites are most appropriate for
individuals with low bandwidth.
Note to Host Sites: You may want to project the Cu-SeeMe signal to
your
participants, rather than having each participant receive it at a
separate
computer, to preserve reflector space for other remote participants.
Note to High Speed Users: As your connection will provide both video
and audio, we encourage you to use a non-text enhanced reflector.
This will preserve the text reflector space for remote particictions.
No to Low Speed Users: Since you will probably choose to receive
only
video through CU-SeeMe, choose a reflector site that is text-
enhanced.
Basic Trouble-shooting:
You will not be able to open a CU-SeeMe session from your Web
browser;
you'll have to open it separately directly from the CU-SeeMe client
software.
If you are having trouble getting the audio connection, you of the
'text-enhanced'
reflectors or
receive the audio by opening
up a RealAudio connection from the Web Site. (See instructions
above.)
Run SDR and look for:
Suggested Uses:
MBONE will send the NASA TV signal to participants. This
technology can
be used in combination with WebChat Discussions and Email to
interact with
the auditorium.
Basic Trouble-shooting:
Make sure you have all of the appropriate protocol drivers properly
installed.
To get the signal, tune your satellite dish to:
Spacenet 2, transponder 5 (channel 9) at 69 degrees west longitude.
(Frequency 3880 MHz. Polarization is horizontal and audio is
monaural at 6.8 MHz.)
Suggested Uses:
Basic Trouble-shooting:
Make sure satellite dish is tuned to the proper location.
