My presentations have audio narrations of varying lengths.
The beginning of the presentation indicates that the users need to
click play to advance from slide to slide, but it appears some
users are unsure when a slide has ended so they sit there for a
while before they get around to hitting the play button to advance
(I don't want to auto-play the presentation because I want them to
have more control over navigation and to prevent them from just
spacing out and losing track of where they are). I find it
annoyingly repetitive to say something like "Click play to
continue" at the end of each slide - and since many slide have
Captivate animations covering the whole screen, having a text
prompt display doesn't seem like it would work very well.
Has anyone experimented with either using some kind of tone
or sound to indicate the end of a slide, kind of like they do on
some language tapes to indicate the user needs to do something? Or
else is there an actionscript way to make the play button highlight
in an obvious way?
