Augmented Reality (AR) superimposes a computer-generated image onto a user view of the real world, providing a composite view.
Augmented reality allows users to gain an enhanced view of the physical, real world, adding computer generated insights beyond the normal boundaries and barriers to sight, sound and touch. Head mounted displays can enhance vision in some way or provide data and information in real time relating to the operational environment.
AR is being used in engineering to turn 3D CAD into augmented reality for engineering reviews, training, servicing and marketing. AR is being used in architecture and town planning to overlay human activity onto 3D models.
AR is being used in surgery to guide surgeons though seeing into the body of a patient. Electricians use head mounted displays for guidance when assembling complicated wiring harnesses.
AR is being used to help people see how furniture will fit into a digital image of a room in their real home. AR is being used to help customers try out different hair styles or cosmetics.
And AR is being used for heads up displays in car windscreens and military aircraft. The technology is proving itself as a very useful tool in everyday lives.
