  • a computer having a memory;

    a pointing device electrically connected to the computer which serves as a virtual keyboard; and

    means for encoding words with alphanumeric characters which correspond to English language characters with a gesture language which is drawn by the pointing device on a surface without the pointing device being lifted from the surface, the pointing device moving one of two distinct lengths of stroke as measured from the origin to a predetermined position about the origin in a predetermined loop motion and the pointing device returning to a relative origin each time an alphanumeric character is drawn, said encoding means disposed in the memory and having special purpose recognition techniques that recognize the gesture language drawn by the pointing device from the predetermined loop motion based on number of clicks, directions, curvature and length of the loop motion.
