<P> The first rough prototype was hacked together in 2011 by Palmer Luckey (then 18 years old) in his parents' garage in Long Beach, California . Coincidentally, John Carmack had been doing his own research and happened upon Luckey's developments as a fellow member of MTBS . After sampling an early prototype, Carmack favored Luckey's approach and just before the 2012 Electronic Entertainment Expo, Id Software announced that their future updated version of Doom 3, BFG Edition, would be compatible with head - mounted display units . </P> <P> In June 2012, during the E3 convention, Carmack introduced a duct taped head - mounted display based on Luckey's Oculus Rift prototype, which ran Carmack's own software . The unit featured a high speed IMU and a 5.6 - inch (14 cm) LCD, visible via dual lenses, that were positioned over the eyes to provide a 90 degrees horizontal and 110 degrees vertical stereoscopic 3D perspective . </P> <P> 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, which was 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 . 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 . </P> <P> The Rift DK1 was released on March 29, 2013, and used 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 was brighter and the color depth is 24 bits per pixel . </P>
