Moreover in can be used for a more detailed and natural interaction with virtual models of organs or other physiological stuctures of the human body. The system provides the means for a user to naturally interact with an augmented version of the previously referred models. The interaction with this models is made through the use of a totally sensor-less Tangible Interface, designated Magic Examiner, which aids the interaction and visualization tasks in the augmented environment.Augmented RealityTangible InterfaceAR Toolkit4D EchocardiographyLVLeft Venlricle of the Heart10.2312/pt.20041512207-212
