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. It is followed by CV1, the first consumer version.

Hardware

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.

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.

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.

System Requirements

Minimum

  • Windows: 7, 8 or 8.1 / Mac: 10.8+ / Linux: Ubuntu 12.04 LTS
  • 2.5+ GHz processor
  • 4 GB system RAM
  • DirectX 10 or OpenGL 3 compatible Video Card[2]

Setup Tutorial

  1. Open the cover on the top, front part of the DK2 headset to make sure that the cable is securely inserted into the 2 ports.
  2. There are 2 connectors, HMDI and USB, at the end of the cable attached the the headset. Plug the HDMI and USB connectors into the correct ports on your computer. If your computer has only a DVI port instead of HDMI, use the DVI to HDMI adapter.
  3. Attach the Sync cable and the USB cable to the right side of the Camera (Sync Cable connector is on top and microUSB connector is on bottom). Connect the other end of the Sync cable to the connector box on the headset cable (where it says Sync Out). Connect the other end of the USB cable to a USB port on your computer.
  4. Place the Camera on a monitor, desk or tripod. The Camera tracks the position of your headset in 3D space. Make sure the lens of the Camera is facing you and there is nothing obstructing the line-of-sight between your head and the camera. The Camera should be placed about 1.5 meters or 5 feet away from you.
  5. Adjust the 2 headset straps so the headset fit comfortably in front of your face.
  6. There are 2 pairs of lenses. The taller lenses (A) are for users with normal and slightly nearsighted visions. The short lenses (B) are for users that are very nearsighted. A Lenses are installed in a new headset. You can switch the lenses with turn and lock-in mechanism. Note that, use A Lenses if you plan to wear glasses or contacts while using the headset.
  7. Adjust the distances between your eyes and the lenses, called eye relief, by turning the screw on the sides of the headset with a coin. Adjust both sides equally.
  8. (Optional) The power adapter is only used to power the USB accessory port (top right) on the headset, you don't need it otherwise. To use it, plug the barrel connector of the power cord to the connector box on the headset cable then attach the power adapter end to an appropriate country's plug then to a power source. Make sure you use only the power adapter supplied with your headset.[3]
  9. Download and install the Oculus Runtime for your OS from https://developer.oculus.com/downloads/.
  10. Run Oculus Configuration Utility (OculusConfigUtil) and configure the headset to your specifications.
  11. Click Tools tab then Advanced tab then Update Firmware. Select and Open the DK2Firmware file to update the firmware of the headset.
  12. Click on Show Demo Scene to make sure everything is positioned correctly.[4]
