25. A method for free-form gesture representation, comprising: recognizing a gesture; converting the recognized gesture into at least one recognition result by using finite-state transducers, each recognition result comprising a sequence of symbols including a set of gesture symbols with a SEM (semantics) placeholder symbol for specific content of the gesture, wherein each symbol of the sequence of symbols identifies a specific attribute of the recognized gesture and the SEM placeholder symbol represents the specific content of the gesture such that when recomposing specific gestural content, the specific content is mapped to the SEM placeholder symbol and other specific attributes are mapped to themselves; generating a recognition lattice based on the recognition result; and outputting the recognition lattice.
