One suggestion based on what I saw from the demo video: give the presenter the option to use either tap or gesture based transitions. It may be easier for the presenter to use gestures since they wouldn't have to look at the device to ensure they're tapping on the correct arrow. A simple double tap anywhere on the screen could bring them back to the index.
