Simple stereoscopic panorama scene for Gear VR

I would like to ask if there is a tutorial or information on how to show stereoscopic panoramas in Unreal Engine. Also what I would like to understand how to add hotspots on to panoramas (i believe these could be just triggered volumes on to sphere which shows panoramas?).
I am interested in creating a stereoscopic panorama virtual tour for Gear VR in the Unreal engine as my android programming knowledge is limited, but I think I can get that done in Unreal Engine - something like this. Also with 3d model preview and hotspots to “enter” space. I think this will be interesting to work on.
I know that you can create panorama by using a skybox texture, but what about stereoscopic and hotspots ?
