Abstract

A data entry system (100, 100'"'"') has an ergonomic base (102, 102'"'"') including upper surface controls (104, 104'"'"') which generate a first set of electrical signals, and side surface controls (106, 106'"'"') which generate a second set of electrical signals when operated independently. A third set of electrical signals are generated when the side surface controls (106, 106'"'"') are operated in combination with the upper surface controls (104, 104'"'"'). Data entry system (100, 100'"'"') further includes mode selection controls (108) for establishing the first, second and third sets of electrical signals as device control signals responsive to a first mode being selected and respective sets of alphanumeric and keyboard control signals responsive to a second mode being selected.

Claims

1. A data entry system combining an ergonomic keyboard and a device controller, comprising:

an ergonomic base adapted to be graspable by two hands of a user, said ergonomic base having an upper surface and a side surface;

upper surface control means disposed on said ergonomic base upper surface and adapted for operation by either of two of a user'"'"'s digits to generate a first set of electrical signals;

side surface control means disposed on said ergonomic base side surface and adapted for operation by at least another of a user'"'"'s digits on either of the user'"'"'s two hands to generate a second set of electrical signals when operated independently and a third set of electrical signals when operated in combination with said upper surface control means; and

,

mode select means disposed on said ergonomic base for establishing said first, second and third sets of electrical signals as (a) respective sets of device input signals, or (b) respective sets of alphanumeric and keyboard control signals responsive to a user'"'"'s selection of one of (1) a device mode, and (2) a keyboard mode.

2. The data entry system as recited in claim 1 where said upper surface control means includes at least one multi-position input device for providing at least four discrete output signals responsive to said multi-position input device being displaced in each of four discrete directions.

3. The data entry system as recited in claim 1 where said ergonomic base includes a pair of hand grip portions extending angularly with respect to said upper surface, each of said hand grip portions being adapted to be gripped by the user'"'"'s fingers, said side surface control means being disposed on said pair of hand grip portions.

4. The data entry system as recited in claim 3 where each of said pair of hand grip portions extend substantially orthogonally with respect to said upper surface.

5. The data entry system as recited in claim 1 where said first and second sets of electrical signals together represent a majority of alphabetic characters of an alphabet in said keyboard mode.

6. The data entry system as recited in claim 5 where said third set of electrical signals represent characters selected from the group consisting of numbers, punctuation, mathematical operators, words and combinations thereof, in said keyboard mode.

7. The data entry system as recited in claim 1 where at least a portion of said first set of electrical signals represent directional control signals in said device mode.

8. The data entry system as recited in claim 1 where at least a portion of said first set of electrical signals represent control signals for a device selected from the group consisting of a video entertainment device, audio entertainment device, television cable tuning device, telephonic device, Internet interface device, game machine, and combinations thereof, in said device mode.

9. The data entry system as recited in claim 1 where said third set of electrical signals are generated by combining operation of said upper surface control means by one of a user'"'"'s hands with operation of said side surface control means by the other of a user'"'"'s hands.

10. The data entry system as recited in claim 1 where said upper surface control means includes at least four switch pushbuttons grouped together on said ergonomic base upper surface.

11. The data entry system as recited in claim 3 where each of said hand grip portions includes support means for assisting in support of said ergonomic base while said side surface control means is being operated.

12. A data entry system, comprising:

an ergonomic base adapted to be graspable by two hands of a user, said ergonomic base having an upper surface and a side surface;

upper surface control means disposed on said ergonomic base upper surface and adapted for operation by either of two of a user'"'"'s digits to generate a first set of electrical signals;

side surface control means disposed on said ergonomic base side surface and adapted for operation by at least another of a user'"'"'s digits on either of the user'"'"'s two hands to generate a second set of electrical signals when operated independently and,

mode select means disposed on said ergonomic base for establishing said first and second sets of electrical signals as (a) respective sets of device input signals, or (b) respective sets of alphanumeric and keyboard control signals responsive to a user'"'"'s selection of one of (1) a device mode, and (2) a keyboard mode.

13. The data entry system as recited in claim 12 where at least a portion of said first set of electrical signals represent directional control signals in said device mode.

14. The data entry system as recited in claim 13 where at least a portion of said first set of electrical signals represent control signals for a device selected from the group consisting of a video entertainment device, audio entertainment device, television cable tuning device, telephonic device, Internet interface device, game machine, and combinations thereof, in said device mode.

15. A data entry system comprising:

an ergonomic housing adapted to be held by two hands of a user;

a plurality of switches mounted on said housing for operation by at least one digit of the user'"'"'s hands;

switching means mounted on said housing for selecting between a first operating mode and a second operating mode; and

,

circuit means for coupling an output of at least a portion of said plurality of switches as game input data responsive to said switching means selecting said first operating mode and converting an output of at least a portion of said plurality of switches to alphanumeric character code data responsive to said switching means selecting said second operating mode.
