Using Webobjects with triggers?

Hello,

I'm creating learning modules for people with poor digital literacy skills, so I need to make things as simple and intuitive as possible. The issue is that I want to use youtube videos, but when i use them as webobjects, the thumbnail of the youtube has that red play button in the middle, which makes people think that they need to click on that button to play the video, but of course that doesn't work- they have to hit the play button in the bottom left corner to start the video. I can't do autoplay because of accessibility issues, so I was wondering if there was a way to set up a trigger so that if anyone clicks on the webobject itself, then it starts playing.  If anyone has other workarounds, i'd love to hear. My only solution is one I hate- transposing a different thumbnail that doesn't have that play button in the middle, but this would require a lot of extra work... Surely there's a better way?

Thanks,

Andrew
