The virtual reality trend is here to stay, with the global VR gaming market expected to be worth $23 billion by 2020.

With the ability to connect people across continents in exciting, immersive experiences, VR (virtual reality) and AR (augmented reality - adding digital elements to a live view, often by the camera on a smartphone; just think Pokemon Go!) are set to be our new reality in the near future.

Currently focusing on sight and sound, the immersive virtual reality experience could soon include touch, smell, and even taste; at last year's Tokyo Game Show, the VAQSO VR - the world's smallest scent-enabling device that can be attached to any VR headset - was unveiled. Impressive!

Virtual reality might look like something from the space age, but it's actually been around for decades.

VR can be traced back to the 1860s, when examples included illusory paintings and theatrical performances. The world's first flight simulator for novice pilots was developed by Edwin Link in the 1920s, and interactive theatre experience The Sensorama was invented in 1957 and patented in 1962.

In 1968, Ivan Sutherland created the Ultimate Display, a head-mounted display attached to a computer that enabled the wearer to enter a virtual world. Today, the installed base of VR headsets is around seven million, set to grow to 37 million by 2020.
