In 1929, Edward Link, an American inventor and aviation enthusiast, created the Link trainer. In his patent application the machine was described as ‘a fuselage-like device with a cockpit and controls that produced the motions and sensations of flying’. We now know it as the original flight simulator, and many see it as an early example of virtual reality.
Studies conducted by Jeremy Bailenson at Stanford showed that VR-training, even with limitations of the rendering systems in 2005, improved learning of physical movements over a two-dimensional video with 25%.
Training for soldiers, pilots, drivers, surgeons, police officers, and other people who are doing dangerous jobs-these are just a few of the hundreds of applications being used. But there are countless ways VR can be used to improve the cognitive skills we use in everyday life. Negotiation, public speaking, carpentry, machine repair, dance, sports, musical instruction-almost any skill can conceivably be improved through virtual instruction.
Virtual Training and Simulation Market is expected to garner $329 billion by 2022, registering a CAGR of 16.8% during the forecast period 2016 – 2022.
