Although Macromedia, the creator of Flash technology,
claims that 98.3% of Internet users have the ability to view
Flash, one has to consider the methodology for the survey and how
well someone can view Flash. For one thing, the survey was
restricted to English speaking participants. In addition,
although the participant would have been warned not to download
the player during the survey, their computer would have automatically
prompted them to do so. More importantly the survey does not
take into consideration the version of Flash they may have and the
speed, memory, and connection of their computer. When you
consider all of the factors, a realistic estimate of the percentage
of Internet users that can view Flash as intended would probably
be closer to 65%.
Should you use Flash on YOUR
web site?
Advantages
Flash uses vector graphics, which means
that the graphics can be scaled to any size without losing clarity/quality.
Flash gives the viewer a "high-tech" impression
of your organization that is very impressive.
Flash can be used to create interactive
animation for entertaining "Splash" pages, ad banners
and even games.
With Flash you can deliver to your
audience engaging applications and web interfaces such as training
courses, tutorials and presentations.
Disadvantages
There are a variety of reasons why Flash
content may be inaccessible. First, Flash files require a plug-in
called the Flash Player. Many older browsers do not support
this plug-in so individuals using those browsers will not be
able to view Flash content.
The "Back" button does not work. If you
navigate within a Flash object, the standard backtracking method
takes you out of the multimedia object and not, as expected,
to the previous state.
Link colors don't work. Given this, you
cannot easily see where you've been and which links you've yet
to visit. This lack of orientation creates navigational confusion.
The "Make text bigger/smaller" button
does not work.
Flash reduces accessibility for users
with disabilities. (Although the latest version "Flash
MX" supposedly addresses many of these issues.)
The "Find in page" feature does not work.
In general, Flash integrates poorly with search.
Internationalization and localization
is complicated. Text that moves is harder to read for
users who lack fluency in the language.
Many viewers get annoyed when they have
to wait for the Flash presentations to load and will end up
going elsewhere instead of waiting.
To Flash or not to Flash... that is the question. The answer
is up to you.
