Crescent, Inc. showed its Immersive Digital Entertainment VR system at the 3D & Virtual Reality Exhibition.The
Immersive Digital Entertainment system makes use of a head-mounted
display, so users can experience a full 360 degree virtual space.
Takahiko Akiyama of 4D Brain, the visual effects art director for the
Final Fantasy movie, also worked on content development.

"Right
now there are industrial designs for this kind of so-called virtual
reality where a person can enter a virtual world in a 360 degree room,
which are used in industry as well as medicine. We think it could also
be used for entertainment. Up until now we have enjoyed these kinds of
scenes on TV and in movies, but it is not like the viewer is actually
inside the space on that kind of screen, so we want to make an
entertainment system where people can enjoy being inside that world."The
Immersive Digital Entertainment platform integrates a wearable
head-mounted display, Virtools real-time rendering technology, image
analysis technology, and super high definition motion capture cameras,
all of which makes it possible to capture the users movements as well as
the items they grasp in the VR space in real time.

"For
example, if a new device were combined with this system the images
could be made to change rapidly depending on what the user is thinking,
so it could be used for relaxation or for biofeedback, as the user could
see changes in the image depending on what the user is thinking, and
then feel changes in himself. That would be more than a simple game, it
would be a new type of entertainment, which is why we wanted to call it
Immersive Digital Entertainment."

There's also an article some where i forgot, that Sony is also experimenting with VR goggles. So... maybe PS4 = VR possibility? :)
