The '''Oculus Rift DK1''' (Development Kit 1) is the first publicly available [[virtual reality]] [[head-mounted display]] from [[Oculus VR]], funded through [[Kickstarter]] in 2012 and shipped in March 2013 at $300. The DK1 featured a 7-inch LCD display at 1280 x 800 resolution (640 x 800 per eye), 110-degree diagonal field of view, and 3DoF rotational tracking via a 1000 Hz IMU. The headset included interchangeable lenses for diopter correction and connected to PC via an external control box. The DK1 is credited with sparking the modern VR renaissance and was open-sourced in September 2014 under Creative Commons and BSD licenses.<ref name="oculus">{{cite web|url=https://en.wikipedia.org/wiki/Oculus_Rift|title=Oculus Rift|publisher=Wikipedia}}</ref>
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.
