Remote Controlled drone equipped with video camera sending a live feed to the guy equipped with the VR Goggles.
The Virtual Reality Goggles have multi-axis orientation sensors, and they control the orientation of the camera on the drone, i.e. if you turn your head to the right, the camera will rotate to the right, etc.
