Augmented Reality is a special technique that makes it possible to show an extra layer of interactive information to the user. For example, you can choose a special pair of glasses in which the image is shown to the user in the lenses. In the military domain, contact lenses are already in use that show extra information to personnel.
The augmented reality (AR) application we see most often can be used with the cell phone. This allows you, for example, to see live which glasses and or garment fits you best. You also see this application when decorating your home. How would this sofa look on this spot?
