Historical Context

  • Origins of VR Concepts: The idea of immersive environments dates back to the 19th century with panoramic paintings and stereoscopes. Morton Heilig’s Sensorama (1962) is considered one of the earliest mechanical attempts at multisensory immersion.
  • First Head-Mounted Displays: Ivan Sutherland’s “Sword of Damocles” (1968) was the first true head-mounted display (HMD), utilizing computer graphics and mechanical tracking.
  • 1980s-1990s Commercialization: Jaron Lanier popularized the term “Virtual Reality” in the 1980s. Companies like VPL Research developed datagloves and early HMDs. Sega and Nintendo attempted consumer VR devices in the early 1990s, but technical limitations led to commercial failure.
  • Military and Aerospace: VR simulators for flight and combat training emerged in the 1970s and 1980s, notably the U.S. Air Force’s Super Cockpit project.
