A head mounted display, or helmet mounted display as it is sometimes called, is a device that is worn by the user on the head or it may be used as part of a helmet. It may have one or two small display optics, such as a tiny LCD screen that is worn like goggles. Usually an HMD is equipped with earphones for sound (often 3D) and position tracking sensors.
Head mounted display technology is available in different formats. Some are compact and simplistic in their design, while others can be rather intricate pieces of equipment. The type that is required by the user depends on the purpose for which the device is needed.
The following are some brief examples of where HMDs may be utilized:
- Aviation – The mechanism may be integrated into a helicopter’s or plane’s design and may be used to provide night vision, as a protective visor, etc.
- Military and law enforcement - used for similar purposes as in aviation but for many other functions as well.
- Scientists and Engineers – Head mounted displays are used when conducting various experiments to see the many sides of complex systems, and during complex operations.
- Gamers – often utilized to create a virtual reality environment.
As you can see, the head mounted display is highly functional and benefits many different operations, helping to advance job performance, aiding in research, and even provides personal entertainment.
