Abstract: It is disclosed an augmented reality system comprising at least one projector, a detection surface and at least one marker. The projector is configured to project a digital image onto a physical object inside a projection volume. The at least one marker is couplable to the physical object and it is adapted to engage the detection surface in at least one point of contact, thus generating a detection signal representative of one or more properties of the point of contact. The detection surface is configured to identify in use an absolute position and an orientation of the physical object coupled to the marker inside the projection volume as a function of the detection signal.
