Navigation - Previous Button
I have a E-Learn with a slide that has several different layers. Ever time the learner is finished with the layer, I want the layer to hid so that they can go back to the main slide then select some...
You could program the PREV button with multiple triggers that either close a layer or go to the previous slide based on conditions that check whether a layer is open (e.g., via tracking layers with variables).
But I wouldn't bother with that. Personally, I think it's more confusing to have the PREV button do double duty. PREV and NEXT should jump to other slides; that's the standard, expected behavior.
- If the layer-opening buttons on the base are still visible/clickable from the layers (e.g., a classic "tab" interaction), then only one click is needed to move between layers. And it's obvious that it's all on the same slide.
- Any "intro" content could also be put on a layer that shows when the timeline starts. I usually give that kind of layer its own "Intro" button, so the user can return to it if needed.
- If the layers are designed to completely cover the base, I suggest making them look like lightboxes: Use a semi-transparent background, so a bit of the base shows through. That lets the user know they are still on the same slide. For closing the layer, use a "Close" button at the bottom and/or an "X" button in the upper right, as desired.
Another option: Instead of using layers, put that content on separate slides and lightbox them. The background of a lightbox actually covers the base and the player -- including the PREV and NEXT buttons. So there's no confusion about what to do. If a user does want to view the previous slide, they just have to close the lightbox before doing that.
