A method of rendering images in an augmented reality system, comprising: capturing an image of a scene in which a virtual object is to be displayed; recognizing a body part present in the captured image; and adjusting (2707, 2708, 2709) a display of the virtual object based upon the recognized body part; wherein recognizing a body part present in the captured image comprises: applying an anatomical analysis to the captured image; the method further comprising: determining whether the body part belongs to a first individual or to a second individual in response to recognizing a body part present in the captured image; determining a location and encompassed area of the virtual object; and determining whether the recognized body part overlaps at least one portion of the area encompassed by the virtual object; wherein adjusting (2707, 2708, 2709) a display of the virtual object comprises: displaying the virtual object superimposed over the recognized body part of the second individual when it is determined that the body part belongs to the second individual; and displaying the virtual object so that the virtual object appears to be located beneath the recognized body part when it is determined that the body part belongs to the first individual. capturing an image of a scene in which a virtual object is to be displayed; recognizing a body part present in the captured image; and adjusting (2707, 2708, 2709) a display of the virtual object based upon the recognized body part; wherein recognizing a body part present in the captured image comprises: applying an anatomical analysis to the captured image; the method further comprising: determining whether the body part belongs to a first individual or to a second individual in response to recognizing a body part present in the captured image; determining a location and encompassed area of the virtual object; and determining whether the recognized body part overlaps at least one portion of the area encompassed by the virtual object; wherein adjusting (2707, 2708, 2709) a display of the virtual object comprises: displaying the virtual object superimposed over the recognized body part of the second individual when it is determined that the body part belongs to the second individual; and displaying the virtual object so that the virtual object appears to be located beneath the recognized body part when it is determined that the body part belongs to the first individual. determining whether the body part belongs to a first individual or to a second individual in response to recognizing a body part present in the captured image; determining a location and encompassed area of the virtual object; and determining whether the recognized body part overlaps at least one portion of the area encompassed by the virtual object; wherein adjusting (2707, 2708, 2709) a display of the virtual object comprises: displaying the virtual object superimposed over the recognized body part of the second individual when it is determined that the body part belongs to the second individual; and displaying the virtual object so that the virtual object appears to be located beneath the recognized body part when it is determined that the body part belongs to the first individual.
