He’s shown using an Oculus DK2 VR Headset and seems to be enjoying it.
Crown Prince of Denmark
amthomsen translated the caption like this:
Sloppy translation: Frederik was for a short period of time undercover, as he equipped special high-tech thermal-vision goggles (direct translation: heat-sensor goggles). Random bypassers could not see that the man in this picture was the Crown Prince of Denmark. Obviously, it was a delight for Frederik to be hidden behind the dark goggles.
The image comes from Reddit.
Reddit is a great place to follow the latest virtual reality happenings.
r/Oculus is by far the most active subreddit and I check it multiple times every day.
r/GearVR is another one that I frequent often. And there are several more with various levels of activity.
Here is the link I use which combines all of the best VR subreddits together.
