The '''Oculus Rift Development Kit 2''' (DK2) is the second development kit [[virtual reality]] [[head-mounted display]] created by [[Oculus VR]]. Released on July 24, 2014 at $350, the DK2 featured significant improvements over DK1 including a 1920 x 1080 OLED display (Samsung Galaxy Note 3 panel), low persistence rendering, and external positional tracking via an IR camera. The DK2 enabled developers to create VR content ahead of the consumer Rift launch and shipped to over 100,000 developers. Oculus open-sourced the DK2 hardware designs under Creative Commons in 2020.<ref name="oculus">{{cite web|url=https://developers.meta.com/horizon/blog/open-source-release-of-rift-dk2/|title=Open Source Release of Rift DK2|publisher=Meta}}</ref>
The '''Oculus Rift DK2''' (Development Kit 2) is the second development [[virtual reality]] [[head-mounted display]] created by [[Oculus VR]], announced at GDC 2014 on March 19, 2014, and released on July 24, 2014, for $350. The DK2 represented a massive leap over the original DK1, featuring a repurposed 5.7" Samsung Galaxy Note 3 OLED display at 1920 × 1080 (960 × 1080 per eye), low persistence rendering to eliminate motion blur, and most crucially, the addition of positional tracking via an included external IR camera—enabling true 6DoF VR for the first time in a widely available headset. With over 100,000 units shipped by February 2015, the DK2 became the de facto development platform for early VR content and proved that consumer VR was not only possible but imminent, directly leading to the consumer Rift CV1 in 2016.
