eye. There is also an optical head-mounted display (OHMD), which is also a
wearable display that has the competence of reflecting images as well as

Head-mounted display is known for its state–of-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
