Will the Web Browser Replace Powerpoint?
By Richard Wiggins
oday is the last
day of Access '97, a conference sponsored by the University
of Calgary with a theme of "Integration or Fragmentation?"
As is so often the case at conferences these days, most speakers
relied on a high-quality LCD projector to show the notes and
graphics related to their talk. (A surprising exception was
a Sun spokesperson, who used old-fashioned transparencies
on an old-fashioned overhead projector.)
As a speaker at the conference, I carefully prepared slides
in Powerpoint, as I've done for dozens of other presentations
I've given around the U.S. and internationally. I noted with
interest that most of the other speakers relied on a different
format for their presentations: HTML.
In many cases, speakers prepared their notes in HTML and downloaded
them to a laptop, or brought them on a floppy for loading onto
the desktop PC the conference organizers installed at the front
of the room. Other speakers relied on live Internet connections
for their talks, visiting the Web sites or Web database gateways
their companies or universities wanted to talk about.
Generally speaking, reliance on live demonstrations means more
fragmented and disjointed talks. At this conference, the attempt
to get ISDN links into the lecture hall failed due to some technical
problem.
Our Internet connection was a dialup link into the University
of Calgary's modem pool, which has the annoying feature of disconnecting
every connection after one hour of use. Although Windows '95 networking
does a nice job of popping up a "Reconnect?" dialog box, the delay
of redialing and the interruption of the speaker's train of thought
is jarring.
But that's not the only problem with a live Internet demo. Most Web
sites are not well-organized for linear exposition with live commentary.
Most Web site developers actually can't do a very good job of a live
walk-through of the site. The audience observes the hapless speaker
going through a number of miscues in presentation and delivery.
One speaker at this conference managed to juggle two PCs that
were navigating different parts of his Web site at once. The effect
was reminiscent of the plate jugglers on Ed Sullivan; it was
entertaining to watch things spin on stage, but I'm not sure it
was the best way to impart useful information.
The folks who downloaded their HTML in its entirety seemed to fare
a little better. They tended to prepare a single "table of contents"
or outline page, which offered hyperlinks to each "slide" or
captured screen shot. The table of contents kept things on track,
and kept the exposition flowing linearly, so the speaker could
cover all of his or her points in the time allotted.
