Abstract

A computing device having a human/machine interface is disclosed. An input device (10) has a plurality of keys (T, 1, 2, 3, 4) each corresponding to a separate digit of the human hand. The keys (T, 1, 2, 3, 4) are arranged to match the relative sequential relation of the digits. The input device (10) is coupled to a processor device (3) in turn coupled to a visual display device (5). The processor device (30) receives instructions or data from the input device (10) and output information to be displayed to the display device (5). The processor device (30) is programmed to cause the visual display of indicia (60-70) wherein each indicium represents a user initiated instruction of data input and is displayed in one-to-one correspondence with the sequential relation of one or more of the keys (T, 1, 2, 3, 4).

Claims

1. A device having a human/machine interface comprising:

an input device having a plurality of keys each assigned only to a specific single digit of the human hand, the keys being physically arranged to match the relative sequential relation of the digits;

a visual display device; and

a processor device receiving instructions or data from the input device and being coupled to the display device, the processor device being programmed to cause the display of a plurality of indicia, wherein each indicium represents a user initiated instruction or data input and is displayed in a manner to indicate which combination of one or more digits effect said instruction or data input, and thus which respective one or more keys are to be activated; and

wherein at least one such indicium is displayed in a manner to indicate that a simultaneous combination of digits effect the represented instruction or data input.

2. The device of claim 1, wherein the visual display device is caused by said processor device to be partitioned into a plurality of non-overlapping regions, each region corresponding to one of the digits, and the regions being in the same sequential relation as the digits, and any one or more regions intersected by an indicium corresponding to the combination of digits and thus keys that give effect to the instruction or data input represented by the indicium.

3. The device of claim 2, wherein the indicia and the regions are arranged orthogonally.

6. The device of claim 1, wherein each indicium is constituted by n first graphical elements and m second graphical elements, the first graphical element representing activation of the respective key and the second graphical element representing non-activation of the respective key.

7. The device of claim 6, wherein said plurality of keys are z in number, and wherein n is in the range of 0 to z, with m correspondingly in the range z to 0.

8. The device of claim 7, wherein z is equal to 5.

9. The device of claim 6, wherein the first graphical element is a stroke and the second graphical element is a dot.

10. The device of claim 6, wherein the first graphical element is a shaded or filled form of the second graphical element.

11. The device of claim 6, wherein the first graphical element is an extended digit and the second graphical element is a retracted digit.

12. The device of claim 2, wherein said plurality of non-overlapping regions are five in number, and said plurality of keys are also five in number.

22. The device of claim 1, wherein said simultaneous combination of digits effect the represented instruction or data input by coincidental release of said keys.

4. A human/machine interface program for implementation on a computing device and carried on a storage medium, the computing device including an input device having a plurality of keys each assigned only to a specific single digit of the human hand, the keys being physically arranged to match the relative sequential relation of the digits, a visual display device and a processor device to give effect to the program, the program comprising:

an input element to receive instructions or data from the input device;

an output element to pass display information to the display device; and

a processing element, coupled to the input element and the output element, to cause the display of a plurality of indicia, wherein each indicium represents user initiated instructions or data and is displayed in a manner to indicate which combination of one or more digits effect said instruction or data input, and thus which respective one or more keys are to be activated; and

wherein at least one such indicium is displayed in a manner to indicate that a simultaneous combination of digits effect the represented instruction or data input.

13. The interface program of claim 4, wherein the visual display device is caused by said processor device to be partitioned into a plurality of non-overlapping regions, each region corresponding to one of the digits, and the regions being in the same sequential relation as the digits, and any one or more regions intersected by an indicium corresponding to the combination of digits and thus keys that give effect to the instruction or data input represented by the indicium.

14. The interface program of claim 13, wherein the indicia and the regions are arranged orthogonally.

15. The interface program of claim 4, wherein each indicium is constituted by n first graphical elements and m second graphical elements, the first graphical element representing activation of the respective key and the second graphical element representing non-activation of the respective key.

16. The interface program of claim 15, wherein said plurality of keys are z in number, and wherein n is in the range of 0 to z, with m correspondingly in the range z to 0.

17. The interface program of claim 16, wherein z is equal to 5.

18. The interface program of claim 15, wherein the first graphical element is a stroke and the second graphical element is a dot.

19. The interface program of claim 15, wherein the first graphical element is a shaded or filled form of the second graphical element.

20. The interface program of claim 15, wherein the first graphical element is an extended digit and the second graphical element is a retracted digit.

21. The interface program of claim 13, wherein said five non-overlapping regions are five in number, and said keys are also five in number.

23. The interface program of claim 4, wherein said simultaneous combination of digits effect the represented instruction or data input by coincidental release of said keys.

5. A method for implementing a human/machine interface for a computing device, the computing device including an input device having a plurality of keys each assigned only to a specific single digit of the human hand, the keys being physically arranged to match the relative sequential relation of the digits, and a visual display device;

the method comprising the steps, implemented on processor means, of;

visually displaying a plurality of indicia on the display device in a manner to indicate which one or more digits effect said instruction or data input, and thus which respective one or more keys are to be activated, wherein at least one such indicium is displayed in a manner to indicate that a simultaneous combination of digits effect the represented instruction or data input; and

effecting a said instruction or data input by the concurrent activation of one or a combination of said keys.

24. The method of claim 5, wherein said simultaneous combination of digits effect the represented instruction or data input by coincidental release of said keys.
