Wearable technology
The creation of the first virtual reality headset can be credited to Cinematographer Morton Heilig. He created a device known as the Sensorama in 1962. The Sensorama was a videogame like device that was so heavy that it needed to be held up by a suspension device.

Virtual reality headsets and viewers have also been designed for smartphones. Unlike headsets with integrated displays, these units are essentially enclosures which a smartphone can be inserted into. VR content is viewed from the screen of the device itself through lenses acting as a stereoscope, rather than using dedicated internal displays. Google released a series of specifications and associated DIY kits for virtual reality viewers known as Google Cardboard; these viewers are capable of being constructed using low-cost materials, such as cardboard (hence the naming).
