Abstract

The present invention pertains to an apparatus for electronically storing alphanumeric characters. The apparatus comprises a computer having a memory. The apparatus also comprises a pointing device electrically connected to the computer which serves as a virtual keyboard. Furthermore, the apparatus comprises means for encoding words with alphanumeric characters with a gesture language which is drawn by the pointing device on a surface without the pointing device having to be lifted from the surface. The encoding means is disposed in the memory. The present invention also pertains to a method for electrically storing alphanumeric characters. The method comprises the steps of a) positioning a pointing device electrically connected to a computer to a relative origin on a surface. Next, there is the step b) of moving the pointing device to a predetermined position relative to the origin in a predetermined motion along the surface while maintaining contact with the surface the entire time. Then there is the step c) of returning the pointing device to the origin along the surface while maintaining contact with the surface the entire time. Next there is the step of repeating steps b) and c) without the pointing device ever losing contact with the surface.

Claims

1. An apparatus for electronically storing alphanumeric characters comprising:

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.

2. A method for electronically storing alphanumeric characters comprising the steps of:

a) positioning a pointing device electrically connected to a computer to a relative origin on a surface;

b) moving the pointing device one of two distinct lengths of stroke as measured from the origin to a predetermined position relative to the origin in a predetermined loop motion along the surface while maintaining contact with the surface the entire time;

c) determining a corresponding alphanumeric character which corresponds to English language characters with a gesture language from the predetermined loop motion based on number of clicks, direction, curvature and length of the loop motion;

d) returning the pointing device to the origin along the surface while maintaining contact with the surface the entire time; and

e) repeating steps b, c and d without the pointing device ever losing contact with the surface.

3. A method as described in claim 2 wherein the positioning step includes the step of placing the pointing device in a still position to define the origin.

4. A method as described in claim 2 wherein the positioning step includes the step of clicking the pointing device so the alphanumeric character is capitalized.

5. A method as described in claim 4 including after the step d), the step of lifting the pointing device off of the surface to encode a space.
