Background: Last summer, I tried to listen to some presentations at NCAR
via webcast. I found it unsatisfying, mainly because of two things:
1) The ppt slides were not very clear, especially when a slide
had multi-panels.
2) The labels for some figures were too small (so I couldn’t
tell which variable was shown along the x-axis, or the y-axis, not to mention
its values or units).
So, before the webcast for the CESM Ocean Model
Working Group Meeting on Jan. 22-23, 2013, I emailed the CESM office with my suggestions
for improvement. Well, the office didn’t think much of them.
To my surprise, the quality of this webcast was
pretty good (except for a tech glitch at the beginning, which didn’t bother me
because I was still in my deep-sleep cycle due to 3-hour time difference and the
fact tat there was no reminder one day before the meeting). The full screen is
like a wide-screen movie. The 1/3 space on the left is split into upper (for
the speaker) and lower (for the meeting’s info) halves, and the rest is used
for showing the ppt. (Some speaker never moved his head once for the entire
15-min talk, the same turned head looking at the ppt screen to his left. Ouch!)
The decent webcast quality motivated me to get up at 5:30 am today, joining other
40 or so colleagues to tune in remotely.
Considering soon or later, we will be giving a talk
to remote audience, which the SciNet will start in 2-3 days, I thought I will
share some thoughts with you so at least you know how a (picky) remote audience
wants.
1) Make each slide is clear, including using large
fonts for writing (I would go for font size 28, but no smaller than 24) and for
labels (you want people to see the variable names and their values and units).
2) Use as few (side by side) panels as possible. Do
not use thumbnail size (unless the main feature is highlight and easy to be glanced
at).
3) Do not show a table with 18 parameters, because you can’t
expect people to read it afar. (What you could do is to highlight a few
parameters and make the rest “nearly invisible” to make a point of how hard you
have worked.)
4) Make sure your ppt is compatible, especially when you have
an embedded movie. (Some Mac user had trouble playing a movie on a PC. Sounds
familiar? It happens too often.)
5) If your pointer cannot be seen by remote viewers, use words
to describe which panel you are referring to: “Notice the red curve in the left
panel; it shows global-mean surface temperature over 100 years."
Of course, more of all, I want to hear a good story.
