Creating a Gaze teleporter / VR (Vive)

Hello, Gurumaid,
could you explain clearer what you have done so i could follow because im doing a project relating to VR gazing teleportation. Like moving room to room / apartment to apartment just by gazing / staring at one specific area/ box / circle and then it teleports.
Im really looking for any hints/ guidance / tutorials video which could help me easier to understand the concept since my blueprint skils is beginner.
Thanks
