Abstract

A system (10) for the fruition of augmented reality by a user comprising a wearable device (100) arranged to project a virtual image overlapped to an image of a real scenario comprising a plurality characteristic points p ij , said wearable device (100) comprising a frame (110) arranged to allow the user to wear the wearable device (100), said frame (110) defining a centre of projection C p . The system (10) also comprises at least one see-through display (120), at least partially transparent, comprising a micro display (121) arranged to emit the virtual image, an ocular lens (122) having a focal distance f 1, an optical combiner (123) arranged to project the virtual image emitted by the micro display (121) in front of at least one eye of the user, said virtual image being focused by the user in a plane Π V at a distance V with respect to the centre of projection C p . The system (10) then comprises a tracking device arranged to carry out a localization of the characteristic points p ij and of the wearable device (100), said characteristic points p ij arranged on characteristic planes Π i located at distances d i with respect to the centre of projection C p . The system also comprises a control unit arranged to receive the localization of the characteristic points p ij and of the wearable device (100) and to operate said or each see-through display (120) for consistently overlapping the virtual image to the image of the real scenario.
