what is augmented reality

Augmented reality (AR) is a technology that integrates digital information with the user's environment in real time. Unlike virtual reality (VR), which creates a totally artificial environment, AR users experience a real-world environment with generated perceptual information overlaid on top. AR can be delivered in a variety of formats, including within smartphones, tablets, and glasses. AR has a variety of uses, from helping in decision-making to entertainment. AR delivers visual elements, sound, and other sensory information to the user through a device like a smartphone or glasses. This information is overlaid onto the device to create an interwoven experience where digital information is added to an environment or masks part of the natural environment. AR is used in many industries, including healthcare, public safety, gas and oil, tourism, marketing, and manufacturing.
