6 . The system ( 100 ) of claim 1 , wherein the image ( 880 ) projected on the eye ( 92 ) of the viewer ( 96 ) comes into contact with said curved mirror ( 420 ) at least two times prior to reaching the eye ( 92 ) of the viewer ( 96 ).
7 . The system ( 100 ) of claim 1 , wherein said curved mirror ( 420 ) is a half-silvered mirror ( 422 ) that is at least partially transparent.
8 . The system ( 100 ) of claim 7 , wherein said half-silvered mirror ( 422 ) permits a plurality of exterior light ( 832 ) to reach the eye ( 92 ) of the viewer ( 90 ), allowing the viewer ( 90 ) to simultaneously view said image ( 880 ) generated by the modulator ( 320 ) and an exterior environment image ( 650 ).
9 . The system ( 100 ) of claim 8 , said system ( 100 ) further comprising a shutter component ( 610 ) that provides for blocking out said exterior light ( 832 ).
10 . The system ( 100 ) of claim 9 , wherein said shutter component ( 610 ) provides for being open and closed by the viewer ( 90 ).
11 . The system ( 100 ) of claim 1 , wherein said partially transparent plate ( 430 ) is at least partially transparent with respect to infrared light.
12 . The system ( 100 ) of claim 11 , said system ( 100 ) further comprising an infrared lamp ( 520 ) that provides for generating a plurality of infrared light ( 830 ) and an infrared camera ( 510 ), wherein said infrared camera ( 510 ) provides for tracking the eye ( 92 ) of the viewer ( 96 ).
13 . The system ( 100 ) of claim 12 , wherein said partially transparent plate ( 430 ) provides for directing infrared light ( 830 ) striking the eye ( 92 ) of the viewer ( 96 ) to said infrared camera ( 510 ).
14 . The system ( 100 ) of claim 13 , wherein at least a subset of said infrared light ( 830 ) traveling between the eye ( 92 ) of the viewer ( 96 ) to the infrared camera ( 510 ) does not come into contact with said curved mirror ( 420 ).
15 . The system ( 100 ) of claim 12 , wherein said infrared camera ( 510 ) is in communication with at least one of: (a) a quad photodiode array; and (b) a CCD.
16 . An apparatus ( 110 ) that provides for being worn on a head ( 94 ) of a viewer ( 96 ) and projecting an image ( 880 ) onto an eye ( 92 ) of the viewer ( 96 ), said apparatus ( 110 ) comprising:
an illumination assembly ( 200 ) that includes a light source ( 210 ) for supplying a plurality of light ( 800 ) to a modulator ( 320 );
an imaging assembly ( 300 ) that includes said modulator ( 320 ) for formulating the image ( 880 ) with the light ( 800 ) from said light source ( 210 );
a projection assembly ( 400 ) that includes a partially transparent plate ( 430 ) and a curved mirror ( 420 ), wherein said projection assembly ( 400 ) provides for projecting the image ( 880 ) formulated by said modulator ( 320 ) onto the eye ( 92 ) of the viewer ( 96 ).
17 . The apparatus ( 110 ) of claim 16 , wherein said apparatus ( 110 ) includes an augmentation mode ( 122 ) that provides for viewing a plurality of exterior light ( 832 ) from an exterior environment ( 650 ) of the viewer ( 96 ) and a tracking mode ( 123 ) that provides for tracking the movement of the eye ( 92 ) of the viewer ( 96 ).
