Oculus Rift DK2 or Development Kit 2 is the 2nd version of [[Oculus Rift]] [[Virtual Reality]] head-mounted display developed by [[Oculus VR]]. It was released on July 24, 2014 for 350 dollars. Released a year after [[DK1]], DK2 is the second version of Oculus Rift intended for developers of [[VR]] content.


==Hardware==
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.
DK2's display is an OLED Pentile panel with a resolution of 1920 x 1080 (1080p). It has higher resolution, lower persistence, more vibrant colors and less "screen door" effect than DK1's display. OLED's advantage over LCD (used by DK1) is that it does emits light and does not require backlight. It allows OLED to produce darker black and more vivid colors. Additionally, the Pentile matrix reduces some of the "screen door" effect while the low persistence display eliminates [[motion blur]] and [[judder]] almost completely. The only negative aspect DK2 when compared to DK1 is that DK2's field of view is a bit lower than that of DK1's.


DK2 has an external camera that tracks your position. Within the camera's view, it tracks IR LED array in the front part of the headset to capture your head's position and movement within the 3D space. The CMOS camera is able to capture your movements up to 60 times per second.
== History and Development ==


DK2 has a built-in latency tester that allows developers to quickly and precisely measure the motion-to-photon latency of their apps and games.
=== DK1 Foundation ===
First generation:
* 2012 Kickstarter
* 720p display
* 3DoF only (no positional)
* Proved VR concept


Note that the DK2's display is literally the [[Samsung Galaxy Note 3]]'s display. If you disassemble the product and remove the display from its casing, you'll even find Samsung's branding on the display.
