1. A computer implemented method for interpreting sign language, comprising: capturing a scene using a capture device, the scene including a human target; tracking movements of the human target in the scene; detecting one or more gestures of the human target in the scene; comparing the one or more gestures to a library of sign language signs; determining a match between the one or more gestures and one or more sign by adjusting a probability weight of each sign based on acquired individual profiles of user motion for users applying know tendencies to motion and gesture detection and grammatical information, and comparing each probability weight against other signs likely to be assigned to a detected gesture; and displaying an output comprising a written language display of a visual translation of the one or more signs on a display device.
