Abstract

A keyboard system permits inputting of data where an input source is responsive to the non-physical touch of fingers. A software program coordinates and interpreting the output signal into discrete letters and other symbols commonly found on a keyboard. A wireless connection can be used, and trigonometrical measurements facilitate location in relation to fingers of a typist. A triangulation device senses finger movement displayed on a monitor, which selectively represents the keyboard. The keyboard allows a typist to be mobile while inputting data into a computer processor.

Claims

1. A keyboard system for permitting typing or inputting of data to a receiving device comprising:

an input source responsive to the non-physical touch of fingers of an operator to generate an output signal;

a receiving device for the output signal; and

a software program with the input source and receiving device for coordinating and interpreting the output signal into discrete letters and other symbols commonly found on a typewriter or computer keyboard.

2. A keyboard system as claimed in

claim 1

wherein the keyboard system takes much less space than a conventional keyboard for a PC computer.

3. A keyboard system as claimed in

claim 1

including means for wirelessly connecting the input device to a computer processor.

4. A keyboard system as claimed in

claim 1

including means for applying trigonometrical measurements of location in relation to fingers of a typist in relation to the input source.

5. A keyboard system as claimed in

claim 1

including means for transmitting the movements of the fingers relative to an input source to a remotely located computer processor, optionally via the Internet.

6. A keyboard system as claimed in

claim 1

including a monitor feedback device for a typist, the monitor being for showing the layout of the keyboard and the outline of the fingers hovering over the keyboard.

7. A keyboard system as claimed in

claim 5

including a triangulation device for determining the relative points in mid air where fingers are located as related to and compared to the outline of the fingers as represented on the monitor.

8. A keyboard system as claimed in

claim 6

wherein the triangulation device senses finger movement displayed on the monitor, which selectively represents the keyboard.

9. A keyboard system as claimed in

claim 1

including means with a computer for transmitting a representation of a computer screen and for having a representation of the keyboard for feedback as to the location of keyboard letters, numbers or symbols, and means for transmitting the representation back to a typist'"'"'s portable wireless computer.

10. A method of operating a keyboard system to permitting typing or inputting of data to a receiving device comprising:

inputting data to an input source

causing the input source to respond to the non-physical touch of fingers of an operator to generate an output signal; and

causing a software program connected between the input source to coordinate and interpret the signal into discrete letters and other symbols commonly found on a typewriter or computer keyboard.

11. A method as claimed in

claim 10

including wirelessly connecting the keyboard to a computer processor.

12. A method as claimed in

claim 10

including using trigonometrical measurements of location in relation to fingers of a typist.

13. A method as claimed in

claim 10

including transmitting the movements of the fingers remotely to a computer processor, optionally via the Internet.

14. A method as claimed in

claim 10

including feeding back information to a typist for showing the layout of the keyboard and the outline of the fingers hovering over the keyboard.

15. A method as claimed in

claim 14

including triangulating information for determining the relative points in mid air where fingers are located as related to and compared to the outline of the fingers as represented on a surface, selectively a monitor.

16. A method as claimed in

claim 15

wherein the triangulation senses finger movement displayed on a surface, which selectively represents the keyboard.

17. A method as claimed in

claim 10

including transmitting a representation of a computer screen for having a representation of the keyboard for feedback as to the location of the keyboard letters, numbers or symbols, and transmitting the representation back to a typist'"'"'s portable wireless computer.
