Augmented reality (AR) takes the real world and projects computer-generated inputs to it. All you need is an appropriate device loaded with relevant software. AR is being developed along with mobile technologies and used for training. Healthcare is one sector that has benefited to a great extent with the help of AR. Doctors can better explain the anatomy of the body or a complex procedure much easier. Military uses AR technology to train soldiers on the enemy locations. In manufacturing industries, workers deal with complex heavy machinery. They must be very careful while operating them.
