Description

Augmented Reality-Based Interface

The present invention relates to an interface, and more particularly, to an augmented reality-based interface capable of outputting a 3D image to a user based on augmented reality.

Augmented Reality is a type of virtual reality that combines the real world seen by the user with the virtual world with additional information. It is also called mixed reality because the virtual world with additional information is combined with the real world and shown as a single image. In other words, by overlapping and showing a 3D virtual image on the real image that the user is viewing, the distinction between the real and the virtual becomes ambiguous.

Based on such augmented reality, a number of technologies for providing an interface between a user and a computer, such as Korean Patent Publication No. 10-2019-0117193, have been proposed.
