Screen-based

A common example of screen-based AR is overlaying digital information over smartphones or tablet camera displays. For example, you switch on and point your smartphone/tablet camera over an object, and the application recognizes that object and overlays that object information, such as the price or description, as digital information over the object image.

Another example of screen-based AR is the video game Pokémon GO, in which, based on the user’s location and direction, digital characters are overlaid over video images.

In the preceding figure, a user is viewing an augmented object, that is, the elephant’s digital object is overlaid over the video frame. This is an example of screen-based AR.
