the visual elements of the principal frames,

the original complex visual images,

additional complex visual images, and

a computer fabrication.

8. A process according to claim 5, wherein:

the salient features of the bridging frame are selected so that the bridging frame presages to the observer the salient features of the subsequent principal frame.

9. A process according to claim 8, wherein:

said visual bridging frame is one of a plurality of such visual bridging frames and said selected salient features are distributed among said plurality of such visual bridging frames.

10. A process according to claim 5, wherein:

each bridging frame is displayed for a period of time which is shorter than the periods of display for the preceding principal frame and the subsequent principal frame.

11. A process according to claim 5, wherein:

each principal and bridging frame may be displayed for a different respective period of time.

12. A process according to claim 5, wherein:

selected bridging frames may be reaccessed and displayed after any one of a group of different preceding frames and before any one of a group of different subsequent frames.

13. A process for the teaching of finger spelling utilizing the manual alphabet, comprising:

(a) determining the primary salient visual features which are to be contained as visual elements of principal frames respectively representing the letters of the manual alphabet;

(b) making a complex visual image as a progenitor of each principal frame of the respective letters;

(c) manipulating each complex image to emphasize the determined primary salient visual features to yield the respective desired visual elements of the respective letter;

(d) dividing the principal frames of the respective letters into groups and subgroups according to their common respective salient features;

(e) determining the primary salient visual features in common of a plurality of pairs of groups and subgroups; and

(f) manipulating an image to provide at least one bridging frame containing selected salient features of the principal frames of said pair, such that the display in sequence of the principal frames of said pair, interposed by the bridging frame, provides an illusion of motion to an observer in the displayed sequence of frames.

14. A process according to claim 13, wherein:

the salient features of the bridging frame are selected so that the bridging frame presages to the observer the salient features of the principal frame of the suceeding letter of the pair of letters.

15. A process according to claim 14, wherein the letters are grouped as follows:

I. Closed Hand Group

(1) A, O, E, S,

(2) T, N, M, E,

(3) C, O, F, D, X;

II. Extended Finger Group

(1) Z, J, I, L, Y,

(2) K, R, U, V, W, D,

(3) F, D;

III. Rotated Wrist Group

(1) G, H,

(2) P, Q.

16. A mechanism for the teaching of finger spelling utilizing the manual alphabet, comprising

a system having means for storing accessing and displaying frames of visual elements;

a plurality of stored principal frames, each respectively containing visual elements of a letter of the manual alphabet;

a plurality of stored intermediate frames, each respectively containing visual elements having salient characteristics related to the salient characteristics of the visual elements of two letters of the manual alphabet;

said system means accessing and displaying a selected sequence of a principal frame of a selected first letter, a selected intermediate frame, and a principal frame of a selected second letter, to provide an illusion of motion to an observer in the displayed sequence of frames.

17. A mechanism according to claim 16, wherein:
