I purchased one pair of these:
This is the sample of what your smart phone is displaying in the 3D glasses.
With this and your smart phone that has VR applications installed, you can get into the "virtual reality world."
The VR worlds interact with the movement of your head;
If you turn your head to the right, you see what's on your right side in the screen.
If you look up, you may see the sky, ceiling, or the surface of the water .. depends on which VR world you are in.
You see the two screens on your right and left next to each other, but from slightly different angles. I assume that's how they create the depth in the flat screen.
You can purchase this from Amazon Japan, the image link below:
And here's my suggestions if you are considering buying the glasses.
Before using this,
- Get your neck stretched and back stretched well.
(unless you get your neck and back hurt by twisting them next couple days after you tried the VR world by looking far around.)
- Remove any objects from the floor.
(unless you get your little toe hit to the corner of the heater and moan like few minutes like me.)
