The SPIN Play HUD adapts depending on if you playing an experience in a SPIN or a Story. To reveal or hide the HUD in SPIN Play
When you are in a SPIN with multiple pieces of media, be it a 360 video or other Stories, then the HUD in SPIN Play will look something like this:
Flanking both sides of the HUD are thumbnails for the next or previous experience in the SPIN playlist. Clicking either thumbnail will take you out of the current experience and to the first scene of the experience you clicked.
Below is the HUD reserved for Stories. Any Story, regardless if it has had interactive elements placed in it (like hyperports and gaze-based images), will have forward and back navigation arrows next to the play/pause button. Theses navigation arrows behave the same way the forward and back arrows behave on an internet browser. When you begin watching a Story they are grayed out, unable to be clicked. When you navigate to another scene you are able to go back to the scene you were just at.
The above HUD is what is looks like to play a SPIN with just one Story in it. If you have a SPIN with multiple Stories, then the HUD will have both the navigation thumbnails and the forward/back navigation.
