Interactive videos with invisible triggers

Hello, 

for an educational project I would like to make an interactive video with fairly simple features: invisible triggers, final statistics of detected and total triggers. For the second part I don't see a problem, however for the invisible triggers, is it possible to make them?

Hi

I could do that with having a transparent image for Image hotspot in Interactive Video.

Hope this helps.
