It's also possible to access the remote control view by going to slides.com in your mobile browser, signing in and navigating to the speaker view URL (slides.com/<username>/<deckname>/speaker).
The remote control page responds to the following touch gestures:
Tap: next slide
Swipe left/right/up/down: change slide in the given direction
The remote control view also shows the elapsed and current time, speaker notes, a presentation progress bar as well as the number of people currently watching a live presentation.
