Sony already has their rival Oculus headset in the PlayStation VR. Now Sony is building its own mobile VR headset to rival the Gear VR. This is according to a patent application from Sony for a head mounted virtual reality device that connects to smartphones.
The patent request is for a device similar to Samsung's Gear VR headset where a Smartphone is inserted into the Head Mounted Display (HMD)

The HMD includes accelerometers and gyroscopes, an on-board processor, on-board memory, and more. The patent also describes an action to set the shutter control logic to switch between left and right eye viewing.
The process, called active shutter 3D, is similar to what 3D TV displays use to trick the eyes into thinking they are seeing objects in three-dimensions. Sony is bringing its TV and smartphone display expertise into a high quality, mobile VR headset designed for its flagship Xperia Z series of phones. Unknown if other phones will also be supported.
The mobile VR headset is also set to use positional tracking techniques that use LEDs and "a plurality of photo diodes" to determine where objects are in the room.
The patent describes a separate device, which could be placed above a TV, that sends out signals throughout the room while the headset reads the data and identifies where the person is in relation to objects in the room. This would be the first mobile based VR device to use tracking in this way.
Since the Smartphone camera is designed to see over the HMD there may be some kind "see-through-mode," which allows the user to switch between virtual reality and a real-world view.
Sony's PlayStation Experience event takes place on 5 and 6 December so we could see more details about PlayStation VR's price and release date or even this Sony mobile VR headset.
