4. Goggles or eyeglasses with a small head-up display such as Google's "Project Glass" beta.

AR is now possible in many fields, thanks to the significant improvements in equipment and devices (Project Glass still in the development stage). AR can assist users in many ways, from navigation to medical, modern warfare to education, and even navigation to navigation.

AR can also be used in architecture, commerce, education, entertainment, and many other areas. It's a rapidly growing technology that has been used in many fields.
