Augmented reality
interactive experience of a real-world environment enhanced by computer-generated perceptual information spatially registered to the user's environment
Augmented reality (often known as AR, not to be mixed with virtual reality and mixed reality.) is a computer technology that shows digital images on top of the current real world. For example it can show a digital table on top of a floor. It is different from virtual reality which makes a person feel they are somewhere else.
