As the name suggests, there is no marker in this type of augmented reality.
It allows the user to overlay/place virtual object(s) in a destined place decided by the user.
For instance, if you want to try a new refrigerator or sofa set in your living room, the type of AR utilized is called markerless AR.
For example, the Queppelin’s furniture retail platform app lets you choose your favorite furniture from their catalog and place it in the desired location selected by you.
