Virtual reality
Around the same time, Douglas Engelbart used computer screens both as input and output devices. In 1968, Ivan Sutherland, with the help of many students including Bob Sproull, created what was widely considered to be the first head-mounted display (HMD) system for use in immersive simulation applications. It was primitive both in terms of user interface and realism, and the HMD to be worn by the user was so heavy that it had to be suspended from the ceiling. The graphics comprising the virtual environment were simple wire-frame model rooms. The formidable appearance of the device inspired its name, The Sword of Damocles.
Jack McCauley
At Oculus, McCauley built Luckey's original prototype into a product for the company’s first Kickstarter campaign, and headed engineering while working on development of the DK1 and DK2 developer kits, both of which were completed in 120 days from concept to shipping. McCauley led production, designed the test equipment and managed production, engineering, and China-based manufacturing of the Oculus Rift, the company's virtual reality head-mounted display.
