Which of the following is NOT correct about Augmented reality ?

Augmented reality is a live direct or indirect view of a physical, real-world environment whose elements are augmented (or supplemented) by computer-generated sensory input such as sound, video, graphics or GPS data.

With the help of advanced Augmented reality technology (e.g. adding computer vision and object recognition) the information about the surrounding real world of the user becomes enhanced but it cannot be interactive.

Augmented reality terminology comes from idea that the technology functions by enhancing one’s current perception of reality.

Augmented reality basically brings out the components of the Digital world into our perceived Real world.
