Abstract

In a preferred form, a keyboard has a single row of eight multi-position keys or groups of key elements with the letters arranged in a standard QWERTY keyboard configuration. The eight keys or key element groups correspond to the eight fingers used when touch typing; each finger operates one key, and that key contains all the letters that the finger normally accesses when touch typing on a standard QWERTY keyboard. With this design, no finger has to move to a different key or key element group while typing. In certain forms, when depressed at different locations on its key face, each key either moves straight down, or down while tilting slightly about one of a plurality of axes. Three-position keys have two tilt axes and six-position keys have five tilt axes. The switches utilize contacts located on the bottom of the switches which may be conductive or nonconductive.

a plurality of the eight groups each having multiple key elements disposed in a generally single- or double-columnar configuration on the keyboard with the eight groups being laterally adjacent to each other on the keyboard so that centers of intergroup laterally adjacent key elements are spaced by a predetermined intergroup spacing therebetween and centers of intra-group adjacent key elements in each single- or double-columnar multiple key element group have less than the predetermined intergroup spacing therebetween to minimize finger movements therebetween during typing therewith.

2. The apparatus of claim 1 wherein the predetermined intergroup spacing is a standard interkey spacing for a full-size keyboard.

3. The apparatus of claim 1 wherein the letters are of the English alphabet so that the predetermined standard touch typing arrangement is a standard QWERTY arrangement, the eight groups of key elements comprises at least five groups of three key elements that each have their key elements disposed in a generally single columnar configuration with three key elements in each group each having a different letter or character associated therewith, and at least two groups of six key elements that each have their key elements disposed in a side-by-side generally double columnar configuration with the six key elements in each group each having a different letter associated therewith.

4. The apparatus of claim 3 wherein the keyboard includes topographical structure that delineates key elements with associated letters that correspond to home row letters for touch typing.

5. The apparatus of claim 3 wherein the five groups of three key elements are each formed on a single key having three distinct activation positions corresponding to the three key elements and associated letters or characters thereof, and the two groups of six key elements are each formed on a single key having six distinct activation positions corresponding to the six key elements and associated letters thereof which allows a user'"'"'s fingers to move or direct an actuation force on the single keys in a manner generally corresponding to finger movements used for touch typing with standard QWERTY keyboards without requiring that any one of the user'"'"'s fingers operate more than one of the single keys for typing of the letters therewith.

6. The apparatus of claim 1 wherein the key elements are either interconnected or separate and distinct from each other.

7. The apparatus of claim 6 wherein the keyboard has a main surface and the key elements are separate and distinct from each other for being pressed during typing therewith.

8. The apparatus of claim 6 wherein the keyboard has a main surface and the key elements are interconnected and connected to the keyboard main surface to form a continuously extending surface therewith.

9. The apparatus of claim 8 wherein the keyboard includes topographical structure for providing tactile feedback regarding location of the key elements on the keyboard.

10. The apparatus of claim 9 wherein the topographical structure is between the key elements and the main surface.

11. The apparatus of claim 9 wherein the topographical structure is raised border portions extending along and between the key elements.

12. The apparatus of claim 8 wherein the topographical structure is a recessed surface of a predetermined one of the key elements in one of the groups of key elements.

13. An apparatus for electronically inputting letters or characters, the apparatus comprising:

a keyboard having eight keys that collectively include all the letters of a predetermined alphabet arranged in a predetermined standard touch typing arrangement thereon;

a surface of the keyboard extending between and including the eight keys; and

a distinct activation position for each letter on the eight keys arranged consistently with the predetermined standard touch typing arrangement.

14. The apparatus of claim 13 wherein the surface is a flat surface.

15. The apparatus of claim 13 wherein the surface has topographical structure that delineate the keys and the activation positions thereof on the keyboard surface to allow for touch typing therewith without requiring that any one of a user'"'"'s fingers operate more than one of the eight keys.

16. The apparatus of claim 15 wherein the topographical structure comprises raised perimeter border portions that extend about the keys.

17. The apparatus of claim 16 wherein the topographical structure comprises raised portions extending on the keys between the activation positions thereof.

18. The apparatus of claim 16 wherein the topographical structure comprises a recessed surface portion on one of the keys with the recessed surface portion corresponding to a predetermined one of the activation positions of the one key.

19. The apparatus of claim 13 wherein the keyboard surface comprises a unitary member having flexible portions thereof.

20. The apparatus of claim 19 wherein the flexible portions correspond to the keys so that the flexible portions are deformed as a user'"'"'s fingers applies pressure to the keys.
