Abstract:
An apparatus for transmitting and displaying graphical representations, comprising:an image generator generating an image of a head including an eye portion correlating to an eye in said head; a non-updating tracker coupled to said image generator, that searches for an eye target image of said eye in said image, wherein said eye portion is positioned at said eye target image and the location of said eye portion is determined; an updating tracker coupled to said image generator, that searches for an updated eye target image when said non-updated tracker is unable to locate said eye target image, wherein said eye portion is positioned at said updated eye target image and said updated eye target image is updated by said eye portion, and the location of said eye portion is determined; an image differentiator coupled to said trackers for providing image differential signals, including eye differential signals representing positional differences determined from the location of said eye portion; and a display device that receives said image differential signals, including eye differential signals, and animates a model with said image differential signals.
