Currently, the only possible movement is forward, as a touch is handled as a click. Possible actions: - touch on left half - backward, touch on right half - forward - swipe left/right -forward/backward
You can go back and forth in presentations using left/right swiping gestures. Note that Qt swipe gestures need three(!) fingers.

We are talking about touch screens, right? Not about touch pad gestures?

Hmm. What's your Okular version? Does three-finger swiping work for you in other Qt applications? Are you able to build Okular yourself to do some debugging? Actually, though, the change-slides-by-swiping code in Okular is extremely short (method PresentationWidget::gestureEvent, in file presentationwidget.cc:589). If that doesn't work it is unlikely to be an Okular problem, simply because all the difficult things happen in Qt and below.
If you can provide the information requested in comment #5, please add it.
To further investigate this issue, KDE developers need the information requested in comment #5. If you can provide it, or need help with finding that information, please add a comment.
I use okular 1.4.70 on my laptop with touchscreen running neon dev unstable. I can go to next page swiping one or two fingers up/down/left/right. To swipe three fingers up/right goes to next page. To swipe three fingers down/left goes to previous page.
Thanks for confirming!
