User wearable eye glasses include a pair of two-dimensional cameras that optically acquire information for user gestures made with an unadorned user object in an interaction zone responsive to viewing displayed imagery, with which the user can interact. Glasses systems intelligently signal process and map acquired optical information to rapidly ascertain a sparse (x,y,z) set of locations adequate to identify user gestures. The displayed imagery can be created by glasses systems and presented with a virtual on-glasses display, or can be created and / or viewed off-glasses. In some embodiments the user can see local views directly, but augmented with imagery showing internet provided tags identifying and / or providing information as to viewed objects. On-glasses systems can communicate wirelessly with cloud servers and with off-glasses systems that the user can carry in a pocket or purse.

The perception of a displayed image is altered for viewers moving relative to the position of the display system screen, thereby imparting a sense of three-dimensional immersion in the scene being displayed. A display generator generates a scene having foreground and background elements, and a display screen displaying the scene. A sensor detects the position of a viewer relative to the display screen, and a processor is operative to shift the relative position of the foreground and background elements in the displayed scene as a function of viewer position, such that the viewer's perspective of the scene changes as the viewer moves relative to the display screen. The foreground and background elements may be presented in the form of multiple superimposed graphics planes, and / or a camera may be used to record the scene through panning at sequential angles. The system may be used to implement virtual windows, virtual mirrors and other effects without requiring viewers or users to modify behavior or wear glasses, beacons, etc.

Method for simulating and demonstrating the optical effects of glasses on the human face
A method is provided for demonstrating an effect of a particular spectacle frame and of optical lenses fitted into this spectacle frame on the appearance of a spectacles wearer as it would be perceived by another person (virtual observer). An image of a face of the spectacles wearer is prepared in such manner that the image can be processes in a computer. An arrangement of the respective spectacle frame in front of the eyes is determined. The image of the face is projected onto a plane by a computation (ray-tracing) of principal rays passing through a center of rotation of an eye of the (virtual) observer to produce a planar image of the face in this plane. Taking into account an optical power of a region, through which a principal ray passes, of each spectacle lens (virtually) fitted in the respective lens rim, and it arrangement in front of the eye, the paths of prinipcal rays which lie within lens rims of the spectacle frame or edges of the spectacle lenses are computed so that an observer of the thus-produced planar image of the face with “worn” spectacles can assess a distortion of the eyes portion of the face by the spectacle lenses and therewith a quality of the spectacle lenses.
