context_page_description: Oculus Rift is a lineup of virtual reality headsets developed and manufactured by Oculus VR, a division of Facebook Inc., released on March 28, 2016.
  In 2012 Oculus initiated a Kickstarter campaign to fund the Rift's development, after being founded as an independent company two months prior. The project proved successful, raising almost US$2.5 million from around 10,000 contributors. Then in March 2014, Oculus was purchased by Facebook for $2 billion.
  The Rift went through various pre-production models since the Kickstarter campaign, around five of which were demonstrated to the public before reaching its commercial release. Two of these models were shipped to backers, labelled as development kits; the DK1 in mid 2013 and DK2 in mid-2014, intended to provide developers with a platform to develop content in time for the Rift's release. However, both were also purchased by many enthusiasts who wished to get an early preview of the technology. The Rift saw its commercial release in March 2016 with the Rift CV1, which was discontinued in March 2019 with the release of its successor, the Oculus Rift S.
context_section_description: Two months after being formed as a company, Palmer's Oculus VR launched a Kickstarter crowdfunding campaign on August 1 of 2012 for their virtual reality headset, named the Rift. The main purpose of the Kickstarter was to get an Oculus Rift prototype—now referred to as DK1 (Development Kit 1)—into the hands of developers to begin integration of the device into their games. The DK1 was given as a reward to backers who pledged $300 or more on Kickstarter, and was later sold publicly for $300 on their website. These kits sold at a rate of 4–5 per minute for the first day, before slowing down throughout the week.
  The Rift DK1 was released on March 29, 2013, and uses a 7-inch (18 cm) screen with a significantly lower pixel switching time than the original prototype, reducing latency and motion blur when turning one's head quickly. The pixel fill is also better, reducing the screen door effect and making individual pixels less noticeable. The LCD is brighter and the color depth is 24 bits per pixel.
  The 7-inch screen also makes the stereoscopic 3D no longer 100% overlapping, the left eye seeing extra area to the left and the right eye seeing extra area to the right, in which there is no 3D depth perception. The field of view (FOV) is more than 90 degrees horizontal (110 degrees diagonal), which is more than double the FOV of previous VR devices from other companies, and is the primary strength of the device. The resolution is 1280×800 (16:10 aspect ratio), which leads to an effective of 640×800 per eye (4:5 aspect ratio). However, since the device does not feature a 100% overlap between the eyes, the combined horizontal resolution is effectively greater than 640. The image for each eye is shown in the panel as a barrel distorted image that is then corrected by pincushion effect created by lenses in the headset, generating a spherical-mapped image for each eye.
  Initial prototypes used a Hillcrest Labs 6DoF head tracker that is normally 125 Hz, with a special firmware requested by John Carmack that makes it run at 250 Hz, tracker latency being vital due to the dependency of virtual reality's realism on response time. The latest version includes Oculus's new 1000 Hz Adjacent Reality Tracker, which aims to provide much lower latency tracking than almost any other tracker. It uses a combination of three-axis gyros, accelerometers, and magnetometers, which make it capable of absolute (relative to Earth) head orientation tracking without drift.
  The Development Kit 1 also included interchangeable lenses that aim to allow for simple dioptric correction.
  The entire source for the Rift DK1 was released to the public in September 2014, including the firmware, schematics, and mechanicals for the device.
