These two devices are often compared, but actually Oculus Rift and Sony HMZ T2 are designed for completely different purposes.
Why was Sony HMZ T2 developed?
Sony HMZ T2 is a home cinema which is designed for watching movies. The idea is very interesting. Imagine that you are watching a film from a distance of 6 meters on the 3D screen with a 5 meters diagonal. It is like being in the cinema without going out of flat.
Why was Oculus Rift developed?
Oculus Rift is a virtual reality headset. When you put it on, you find yourself in the virtual world. Oculus Rift is ideal for 3D games, as it provides a full immersion in the virtual world.
Unfortunately, watching a movie via Oculus Rift will be much worse than via Sony HMZ T2. The prolem is the field of view. With a screen resolution of 1920×1080 the picture will look as if you look at the 6-meter painting, made of squares with sides of 1 centimeter. For gaming, the main thing is immersion in the virtual world, the player is constantly in motion and graphic quality plays a secondary role. But watching movies with grainy images is definitely unpleasant.
In general, Oculus Rift will need quite different techniques of filming. Cinema is a quite conservative thing, so until there are no “Oculus Rift Cinema”, there will be no films in this format.
Therefore, if you need a home 3D cinema, Sony HMZ T2 is what you need. If you want a full immersion into the world of virtual reality – your choice is Oculus Rift.
