PlayStation eyes up PS4 VR headset

Sony has filed a number of patents that could indicate a PS4 virtual reality headset is on the way.

The patents, which detail an audio system and head mounted display, were first spotted on popular web forum NeoGAF.

Highlighted within the audio system patents are methods of alerting players to real-world emergencies, while details of the head mounted display refer detail head motion detection and imagine stabilisation.

Both patents together would certainly indicate a device capable of rivalling the Oculus Rift.

Revealed yesterday, the patents were filed by Sony back in May 2013. Internally, the device has been demonstrated with first-party racing title DriveClub.

The device is expected to make its debut next year, with a potential reveal scheduled for Gamescom 2014.
