Remote Controlled drone equipped with video camera sending a live feed to the guy on the left, who is wearing Virtual Reality (VR) goggles. The VR 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.
