Abstract

A programmatic organisation method, or concept, for augmented use of a standardized keyboard, capable of detecting depression/touching of single keys as well as simultaneously depressed/touched combinations of keys. According to the invention, simultaneous depression/touching of two or more adjacently or non-adjacently located keys of said keyboard is decoded as a predetermined character, symbol, note, action etc., whereby the input capability of the keyboard is considerably enhanced. Advantageously are predetermined functions, e.g. a “shift” (“CAP”) or num lock function by predetermined single keys or predetermined key combinations, i.e. the input capability can thus be enhanced even further, each such function resulting in a new and independent input capability The keyboard may advantageously be a conventional numerical 3×4 keyboard.

Claims

1. A programmatic organization method for chordic input by using a standardized keyboard with an enhanced input capability arranged capable of detecting depression/touching of single keys as well as simultaneously depressed/touched combinations of keys, wherein simultaneous depression/touching of two adjacently located keys of said keyboard is decoded as a predetermined input in a chosen input mode;

and wherein the chosen mode is obtained by simultaneously depressing/touching predetermined combinations of keys that are separated by one key.

2. The method as claimed in claim 1, wherein the chosen mode is obtained by predetermined single keys.

3. The method as claimed in claim 1, wherein the keyboard forms a part of an input system utilized for user verification.

4. The method as claimed in claim 1, wherein data input is shown on a display unit.

5. The method as claimed in claim 1, wherein data input is made audible to a user by music or speech synthesizing circuits.

6. The method as claimed in claim 1, wherein resulting characters, symbols etc. form various key combinations are shown adjacent to each key of the keyboard.

7. The method as claimed in claim 1, wherein resulting characters, symbols etc. from various key combinations are disclosed or shown in a preferably detachable keyboard overlay.

8. The method as claimed in claim 1, wherein a joystick function is participating in the inputting of data.

9. The method as claimed in claim 1, wherein various keyboard layout, including numerical, alphanumerical, symbols, are selectable from a table.

10. A method as claimed in claim 1, wherein various keyboard layout, including numerical, alphanumerical, symbols, are user selectable by depression of one or more predetermined keys.

11. The method as claimed in claim 1, wherein simultaneous depression/touching of two adjacently located keys numbered “

1”

though “

9”

of said keyboard is decoded as a predetermined input in a chosen input mode.

12. The method as claimed in claim 1, wherein the keyboard is a conventional numerical 3×

4 keyboard, covering “

0”

through “

9” and

including up to two additional keys.

13. The method as claimed in claim 12, wherein the keyboard includes at least one further key.

14. The method as claimed in claim 1, wherein the keyboard forms a part of a telephone, including preferably a mobile telephone.

15. The method as claimed in claim 14, wherein the telephone is capable of inducing/outputting more than one DTMF-digit simultaneously.

16. A telephone instrument capable of generating and outputting more than one DTMF-digit simultaneously, said instrument comprises, a standard keyboard with an enhanced input capability arranged capable of detecting depression/touching of single keys as well as simultaneously depressed/touched combinations of keys, wherein simultaneous depression/touching of two adjacently located keys of said keyboard is decoded as a predetermined input in a chosen input mode;

and wherein the chosen mode is obtained by simultaneously depressing/touching predetermined combinations of keys that are separated by one key.

17. A handheld computer having a standard numerical keyboard as an attached or integrated member, single key and simultaneous adjacent two-key user input being decoded as numerals, characters, symbols according to predetermined keyboard layouts.
