1. A liquid crystal device comprising:

  • (a) a front electrode layer;

    (b) a rear electrode layer;

    (c) a liquid crystal material located between said front electrode layer and said rear electrode layer;

    (d) changing an electrical potential between said rear electrode layer and said front electrode layer to selectively modify portions of said liquid crystal material to change the polarization of the light incident thereon;

    (e) a plurality of light sensitive elements located together with said rear electrode layer; and

    (f) a processor that determines the position of at least one of said plurality of light sensitive elements that has been inhibited from sensing ambient light, whereby said processor distinguishes between ambient surroundings and said at least one of said plurality of light sensitive elements said inhibited from sensing said ambient light.
