Totaal N00B question for VIVE VR

I’m a total n00b regarding VR in UE4. Have been using it for archviz r&d.

My question is this:
I have a 360 image/video. Shot from a tripod. I’d map that on a sphere in ue4. Then somehow create markers that light up when you point with your HTC VIVE controller (pulling the trigger).
Where do I have to start for this? Any tutorials / documentation that comes close to this idea?

Sorry for this n00b question might be asked a 10000 times…
