PlayStation VR

PlayStation VR, known by the codename Project Morpheus during development, is a virtual reality head-mounted display developed by Sony Interactive Entertainment,[3] which launched on October 13, 2016.[1]
It was designed to be fully functional with the PlayStation 4 home video game console. In certain games and demos for the VR, the player wearing the headset acts separately from other players without the headset. The PlayStation VR system can output a picture to both the PlayStation VR headset and a television simultaneously, with the television either mirroring the picture displayed on the headset, or displaying a separate image for competitive or cooperative gameplay. PlayStation VR works with either the standard DualShock 4 controller or the PlayStation Move controllers.[4]
The PlayStation VR has a 5.7 inch OLED panel, with a display resolution of 1080p.[5][6] The headset also has a processor box which enables the Social Screen video output to the television, as well as process the 3D audio effect, and uses a 3.5mm headphone jack.[5][7]The headset also has nine positional LEDs on its surface for the PlayStation Camera to track 360 degree head movement.[5][8]
As of February 19, 2017, PlayStation VR had sold 915,000 units.[2][9]

History[edit]

Sony's interest in head-mounted technology dates back to the 1990s. Its first commercial unit, the Glasstron, was released in 1997.[10] One application of this technology was in the game MechWarrior 2, which permitted users of the Glasstron or Virtual I/O's iGlasses to adopt a visual perspective from inside the cockpit of the craft, using their own eyes as visual and seeing the battlefield through their craft's own cockpit.[11]
In early 2014, Sony Computer Entertainment research and development engineer Anton Mikhailov said his team had been working on Project Morpheus for more than three years. According to Mikhailov, the PlayStation 3 Move peripheral, itself revealed in June 2009, was designed with unspecified, future head-mounted technology in mind. "We specced it and built it to be a VR controller, even though VR wasn’t a commodity. As engineers, we just said it was the right thing to do. At the time, we didn't have a consumer-grade project that we could work on, but it was definitely designed with that vision in mind."[12] Shuhei Yoshida, the president of Sony's worldwide studios, also said the project started as "grassroots" activity among engineers and programmers, which came into focus in 2010 once the Move controller had been released.[13] Sony also went on record to say it is mandatory for all games to have no less than 60 frames per second at all times.[14]
Project Morpheus was first announced at The 2014 Game Developers Conference. Sony Computer Entertainment Worldwide Studios president Shuhei Yoshida introduced the device on March 18, 2014 and stated Project Morpheus was "the next innovation from PlayStation that will [shape] the future of games."[15]
On September 15, 2015, it was announced that Project Morpheus would be officially named PlayStation VR.[16] Later in 2015, Sony acquired SoftKinetic, a tech startup whose focus includes visual depth-sensing gesture recognition, for an undisclosed amount.[17]
On October 13, 2016, Sony released the Playstation VR with price tag of $399 in the US, €399 in Europe, £349 in the UK, and 44,980 yen in Japan.[18][19]

Hardware[edit]

The prototype revealed at GDC'15 included an OLED 1920 × 1080 pixel display (providing 960 × 1080 pixels resolution per eye) with an RGB subpixel matrix,[6] and is capable of displaying content at 120fps.[1] It features an FOV of 100°, 6DOF head-tracking, stereoscopic 3D, and unwarped output to a TV, either for others to view what the headset wearer sees, or a separate display to compete against the headset user using a standard PS4 controller.[20]
In September 2015 it was revealed the headset would have three rendering modes for developers to choose from: native 90 Hz, native 120 Hz, and a mode where gameplay running at 60 Hz would be displayed at 120 Hz using a motion interpolation technique called asynchronous reprojection.[21] The interpolation would be achieved with little system resources and a small latency of under 18 milliseconds. The technique would also be utilised in the native 120 Hz mode to ensure consistent framerate.[22] According to a Sony representative the company expects the interpolated 120 Hz mode to be a popular choice for games.[21]

PlayStation VR games can send different perspectives to the headset and television. Shuhei Yoshida, president of SIE Worldwide Studios, explained in regards to a demo by SIE Japan StudioMonster Escape (in which four players playing off the TV must evade a monster controlled by a player using the headset), that this ability allowed VR to become an asymmetric "social experience", similarly citing the existing game Keep Talking and Nobody Explodes as another example of a VR-compatible game that emphasizes interaction.[23]

Games and content[edit]

In March 2016, Sony said there were 230 developers actively working on content for PSVR, with 50 titles available by the end of the year.[24]
Existing, non-VR games can be played within PlayStation VR via "Cinematic Mode", which renders the content on a simulated projection screen in a 3D space. The mode has three screen size options, ranging up to 226 inches (18.8 ft) in virtual size. PlayStation VR also supports the display of 360-degree photos and video.[25] Other features, such as Share Play and Live from PlayStation, are also compatible within the headset.[26]

Marketing[edit]

"Our biggest challenge will be to get people demoing VR. Because there's no way to sell VR until you've tried it... You can watch over the shoulder, you can read articles, but – and I mean this genuinely – everybody that I know who has tried PlayStation VR has taken off their headset with a smile, and said 'wow'. So you've got to try it. That's the challenge."
Michael Ephraim, SIE Australia[27]
Prior to release, Sony predicted that interest in the headset would build steadily over time, through word of mouth.[27][28]
PlayStation VR was first demonstrated on The Tonight Show Starring Jimmy Fallon, and as a playable concept during E3 2014.[29] The device was also featured at Sony's PlayStation Experience Expo in Las Vegas in December 2014.[30] Sony announced new information regarding Project Morpheus at the 2015 Game Developers Conference, in line with the official schedule posted on their website[31] and released updated specifications.[32]
In an interview with Nikkei Japan in March 2016, Sony indicated the possibility of enabling use of the PlayStation VR in connection with a PC. This would allow the device to work with platforms extending further than the PlayStation 4.[33]
