Abstract

A unique keyboard configuration and a keyboard form factor are provided. The keyboard configuration is formed from several keys arranged in a substantially handprint configuration on a housing. Each key is assigned more than one letter input. To actuate any one of the letter inputs assigned to a key, only a single actuation of the key is needed. Each key may be momentarily movable to more than one position, from the rest position, each position corresponding to generating a pre-assigned letter input.

Claims

1. An input device for entering data into a computing device, the input device comprising:

a supporting structure;

a plurality of primary keys mounted on the supporting structure, and

at least one of the primary keys comprising a multi-function input device operable by a single finger of a user and having a plurality of actuation modes each of which is associated with different input data for the computing device,

wherein the multi-function input device comprises a pad mounted over a plurality of momentary action switches whereby rocking the pad in each one of a plurality of directions operates a corresponding one of the switches;

wherein the multi-function input device further comprises a further switch which is operated by depressing the pad without rocking it;

wherein the multi-function input device further comprises five switches whereby rocking the pad in each one of four directions on substantially perpendicular axes operates a corresponding one of four switches and depressing the centre of the pad operates the fifth switch.

5. The input device as claimed in claim 1 wherein a first secondary key is provided to perform a shift function and operation of each of the primary keys generates one of a plurality of un-shifted inputs or one of a further plurality of shifted inputs.

6. The input device as claimed in claim 5 wherein five primary keys are positioned relative to one another along approximately arcuate line such that the tips of the four fingers and thumb of a user'"'"'s hand will naturally adopt the positions of the primary keys;

each primary key is assigned a maximum of one actuation mode associated with an input data value comprising a vowel selected from the group of “

a”

, “

e”

, “

i”

, “

o” and

“

u”

;

wherein

an “

s”

, an “

a”

, an “

l” and

a “

c”

are assigned to a first of the primary keys,

a “

d”

, an “

i”

, an “

m” and

a “

p”

are assigned to a second of the primary keys,

an “

f”

, a “

v” and

an “

x”

are assigned to a third of the primary keys,

a “

z”

, a “

q” and

a “

j”

are assigned to a fourth of the primary keys,

a “

w”

, a “

u”

, a “

k” and

a “

y”

are assigned to a fifth of the primary keys.

a “

t”

, an “

e”

, an “

r” and

an “

n”

are assigned to a first secondary key, and

an “

h”

, an “

o”

, a “

b”

, and a “

g”

are assigned to a second secondary key.

9. The input device as claimed in claim 6, wherein the third secondary key is located proximate to one of the primary keys, wherein the third secondary key and the proximate primary key are alternatively accessible by a single finger or thumb;

wherein

a fourth secondary key is located proximate to another of the primary keys, wherein the fourth secondary key and the proximate primary key are alternatively accessible by a single finger and the second secondary key also provides a shift function

11. The input device as claimed in claim 1, further comprising a positioning device arranged proximate to one of the primary keys, wherein the positioning device and one of the primary keys are alternatively accessible by a single finger in use.

12. The input device as claimed in claim 1, further comprising adjustment means associated with at least one of the primary or secondary keys wherein the position of the associated primary or secondary key is movable relative to the other keys by operating the adjustment means.

13. The input device according to claim 12, wherein the adjustment means comprises a knob or lever.

14. The input device as claimed in claim 5, wherein the supporting structure includes an opening formed in the supporting structure to receive a hand and the primary and the secondary keys are located in the opening and accessible by placing a hand in the opening.

15. The input device as claimed in claim 14, wherein the supporting structure is contoured to conform to a hand.

16. The input device as claimed in claim 14, wherein the supporting structure is arranged to be worn on a person.

17. The input device as claimed in claim 16, wherein the supporting structure is a glove.

18. The input device as claimed in claim 17, wherein the undersurface of the glove includes a screen.

19. The input device as claimed in claim 1, the input device being incorporated in a computing device further comprising:

a display; and

a processor capable of receiving data from the input device and outputting the data on the display, wherein the input device is a keyboard comprising;

a housing; and

a plurality of keys mounted in the housing, at least some of the keys being positioned relative to one another along an approximately arcuate line such that the tips of the four fingers and thumb of a user'"'"'s hand will naturally adopt the positions of the primary keys.

2-4. -4. (canceled)

7-8. -8. (canceled)

10. (canceled)

20. An input device for entering data into a computing device using a single-hand operation, the input device comprising:

a supporting structure; and

a plurality of keys mounted in the supporting structure, at least a portion of the keys being positioned relative to one another along an approximately arcuate line such that the tips of the four fingers and thumb of a user'"'"'s hand will naturally adopt the positions of the primary keys,

wherein each of the keys is assigned a plurality of inputs, each of the inputs is generated by a single actuation of a corresponding key, and

wherein the keys are capable of generating inputs corresponding to a full range of English letters.
