We propose a solution to manipulate virtual objects without using markers, i.e. we replaced the physical marker by user face. For this we had to develop also a method to manipulate the virtual models (e.g. to rotate models) based on user gesture allowing doing the same as the marker. Finally we present a simple augmented web game showing our approach without the use of markers.Augmented reality without markersAugmented web gameGestural interface10.2312/pt.20101179189-192
