Abstract

The present invention relates to a micro-keyboard simulator, and more particularly to a micro-keyboard simulator whose operating surface for inputting commands includes two pressure inductive stages. It comprises a first pressure inductive device and a second pressure inductive device, wherein the first pressure inductive device is capable of detecting finger touch and analyzing coordinates and connects to a mainframe so as to display at least one symbol table on the monitor and the symbols of the symbol table are mutually corresponding to the surface coordinates of the micro-keyboard simulator; and the second pressure inductive device is capable of detecting the press-down action of the finger. Through the abovementioned combination, it greatly reduces the volume of the keyboard and is able to know the pressed character in advance so as to reduce the frequency of the user glancing at the keyboard.

Claims

1. A micro-keyboard simulator, which including two pressure inductive stages, comprising a first pressure inductive device, and a second pressure inductive device, wherein:

said first pressure inductive device is capable of detecting finger touch and analyzing coordinates and operates in coordination with at least one symbol table in which the symbols of said symbol table are mutually corresponding to the surface coordinates of said micro-keyboard simulator; and

said second pressure inductive device is capable of detecting the press-down action of the finger to execute the command inputting tasks.

2. The micro-keyboard simulator as set forth in claim 1, wherein said first pressure inductive device is a resistance-type pressure inductive panel.

3. The micro-keyboard simulator as set forth in claim 1, wherein said first pressure inductive device is a capacitance-type pressure inductive panel.

4. The micro-keyboard simulator as set forth in claim 1, wherein said second pressure inductive device is installed underneath said first pressure inductive device.

5. The micro-keyboard simulator as set forth in claim 1, wherein said second pressure inductive panel is a resistance-type pressure inductive panel.

6. The micro-keyboard simulator as set forth in claim 1, wherein said second pressure inductive device is a capacitance-type pressure inductive panel.

7. The micro-keyboard simulator as set forth in claim 1, wherein said second pressure inductive device is a press switch.

8. The micro-keyboard simulator as set forth in claim 1, wherein the surface of said first pressure inductive device has tactile embossing dots for the user to quickly differentiate location.

9. The micro-keyboard simulator as set forth in claim 1, wherein said first pressure inductive device and said second pressure inductive device are composed of a single pressure inductive device so as to distinguish whether the first-stage inductive signal or the second-stage inductive signal according to the magnitude of finger pressure received by said single pressure inductive device.

10. The micro-keyboard simulator as set forth in claim 1, wherein said symbol table are displayed on the monitor.

11. The micro-keyboard simulator as set forth in claim 1, wherein said symbol table displayed on said monitor is dependent upon different input requirements so that the software provides different corresponding symbol tables.

12. The micro-keyboard simulator as set forth in claim 1, wherein said symbol table displayed on said monitor is controlled by more than on independent said micro-keyboard simulator.

13. The micro-keyboard simulator as set forth in claim 1, wherein said first pressure inductive device is activated when touched by the finger and said symbol on said monitor disappears when the finger moves away from said first pressure inductive device.

14. The micro-keyboard simulator as set forth in claim 1, wherein when the finger touches and moves said first pressure inductive device, the symbol of said symbol table on said monitor generates different prompt signals corresponding to the coordinates of finger locations, e.g., the change of color or the signal of alter-shaped symbol, for the user to verify, so that the user is able to verify the selected symbol in advance before pressing the key.

15. The micro-keyboard simulator as set forth in claim 1, wherein said coordinator analyzing capability is that there are different corresponding one-dimensional coordinate values corresponding to the different locations on the surface of said micro-keyboard simulator.

16. The micro-keyboard simulator as set forth in claim 1, said coordinator analyzing capability is that there are different corresponding two-dimensional coordinate values corresponding to the different locations on the surface of said micro-keyboard simulator.
