Oculus Rift DK2
The Oculus Rift DK2 Is the second official ‘Developer Kit’ release of the Oculus Rift Virtual Reality Headset. It was announced on March 14, 2014 at the Games Developer Conference in San Francisco, and began shipping in July 2014.
It features several improvements over the first development kit, such as having a higher-resolution (960×1080 per eye) low-persistence pentile AMOLED display, higher refresh rate, head positional tracking, a detachable cable, and the omission of the need for the external control box.
A teardown of DK2 revealed that it incorporates exactly the same screen as the Samsung Galaxy Note 3 smartphone, including the front panel from the device itself.
In September 2014, another updated version was revealed, codenamed ‘Crescent Bay’, which has a greater resolution than the DK2, a lower weight, built-in audio, and 360-degree tracking thanks to the presence of tracking LEDs in the back of the headset.
