Oculus Rift DK 1 or Development Kit 1 is the first version of [[Oculus Rift (Platform)|Oculus Rift]] [[Virtual Reality]] [[head-mounted display]] released by [[Oculus VR]]. DK1 was released on March 29, 2013 for 300 dollars. A Kickstarter campaign for DK1 begin in August 2012. Pre-orders for DK1 became available on Oculus' website on September 26, 2012. DK1 is intended to be used by [[#Developers|developers]] and hardcore VR enthusiasts to create [[VR]] content. It was discontinued after the release of [[Oculus Rift DK2]].


On January 5, 2016, Oculus VR announced that the original Kickstarter backers of DK1 will receive a special Kickstarter Edition of the [[Rift]].
The '''Oculus Rift DK1''' (Development Kit 1) is the first development [[virtual reality]] [[head-mounted display]] created by [[Oculus VR]], launched via Kickstarter on August 1, 2012, and released to backers on March 28, 2013, for $300. The DK1 is widely credited with reigniting the modern VR industry after years of dormancy, demonstrating that affordable consumer VR was achievable with smartphone-era components. Featuring a 7-inch LCD display split into 1280 × 800 resolution (640 × 800 per eye), a 110° diagonal field of view, and 3DoF rotational tracking via a 1000Hz 9-axis IMU, the DK1 delivered a prototype VR experience that convinced developers, investors, and the public that VR's time had finally come. Despite its limitations—no positional tracking, significant motion blur, and screen door effect—the DK1's Kickstarter raised $2.4 million (on a $250,000 goal) and ultimately led to Facebook's $2 billion acquisition of Oculus VR in 2014.
==Hardware==
Oculus Rift DK1 is a large, black, goggle-like device that is strapped across your eyes. There are cushions lining the sides of the goggles to give you comfort. The display of DK1 is a RGB LCD screen with a resolution of 1280 x 800 or 640 x 800 per eye. It has a diagonal FOV of 110° and horizontal FOV of 90°.


Oculus Rift DK1 tracks the rotational movement of your head with [[Gyroscope]], [[Accelerometer]] and [[Magnetometer]]. It allows you to look around and become immersed in the virtual world. The overall latency is about 50 to 60ms.
== History and Development ==


It comes with 3 different pairs of lenses along with the ability to adjust the focal lengths of the display. The material of the actual lenses is either polycarbonate or acrylic.
=== Palmer Luckey Origins ===
Inventor background:
* VR enthusiast since teenage years
* Collected vintage VR headsets
* Built prototypes in garage
* Breakthrough design insight


While DK1 offers a fairly immersive experience, it is not perfect. When using the device, motion blur is quite apparent. It also has pixelation due to low resolution and the appearance of looking through a [[screen door]].
=== Kickstarter Campaign ===
August 1, 2012:
* $250,000 goal
* Raised $2.4 million
* 9,522 backers
* Industry attention


In addition to the head-mounted display, DK1 has a brick-like device called the control box. User must connect the HMD to the control box before it can be hooked up to PC. Along with various I/O ports such as HDMI, DVI, Mini USB and DC connector, Control box allows the user to change the brightness and contrast of his or her display. The video input for the HMD is DVI. The control box changes PC's HDMI output into DVI.

#Remove the DK1 headset and Control Box from the case. headset is attached to the Control Box through a cord.
* [[Oculus VR]]
#Adjust the headset strap (lateral) so the headset fit comfortably in front of your face. Use and adjust the over-the-top strap if needed.
* [[Oculus Rift DK2]]
#There are 3 pairs of lenses. The taller lenses (A) are for users with perfect or farsighted vision. The short lenses (B) and (C) are for users that are nearsighted. B is for moderately nearsighted users while C is for very nearsighted ones. 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.
* [[Oculus Rift CV1]]
#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.
* [[Palmer Luckey]]
#Control Box is the square attached to the DK1 through a cord. It has 4 connectors: USB, Power, HDMI and DVI.
* [[VR History]]
#Attached the USB cable to the Control Box and your computer.
* [[Kickstarter VR]]
#Plug the power cord to an outlet and connect it to the Control Box.
#Use either the HDMI or DVI and connect it to the same type of port on your computer.
#Turn on the Control Box with the power button. The other buttons adjust brightness and contrast of the headset display.<ref>http://static.oculus.com/sdk-downloads/documents/Oculus_Rift_Development_Kit_Instruction_Manual.pdf</ref>
#Download and install the Oculus Runtime for your OS from https://developer.oculus.com/downloads/.
#Right click your desktop and go to ''Screen Resolution'' or go to ''Display Settings''. There are 2 Displays, one of them is Rift DK. Under the ''Multiple displays:'' tab, select ''Duplicate these displays''.
