Sony announced its prototype for a virtual reality headset for the PlayStation 4 console, at a developers conference, in San Francisco, US, Bbc.com reported on March 19.

Shuhei Yoshida, president of Sony\'s Worldwide Studios, said they have been working on the technology - Project Morpheus - for three years.

In a blog post, Yoshida went on to say, "We believe VR will shape the future of games.”

The prototype will be available to developers, but no commercial release date has been given.

Project Morpheus is a head-mounted display with 1080p resolution and a 90 degree field of vision, with built-in sensors that can track head orientation and movement so that, when a user\'s head moves, the image of the virtual reality world moves with it.
