Head-mounted display is known for its stateof-art display capabilities. HMD

apart from providing high quality display is also capable of providing

supplementary services like access to internet, GPS, navigation and so on.

HMD differs in whether they can display just computer generated

images or show live images from the real world or combination of

both.

According to MarketsandMarkets, the head-mounted display is expected to

reach up to $12.28 billion by 2020, an estimated CAGR of 57 percent from

2014 to 2020. The major driving force behind this is, rise in technological

expansion, video gaming industry, decreased cost of micro-display and

government curiosity in training defense staff in simulators
