Abstract

The present invention relates to a touch inductive key, and more particularly to a key that is able to give out a response prompt when senses finger touching it so as to improve the input accuracy and decrease the frequency user required glancing at the key. The key is a pressure activated key, which comprises a key entity, and a touch inductive panel on top of the key entity connecting to a response system so that it is able to allow the user to know the character of the key under the finger through the response prompt generated by the response system when he or she touches the touch inductive panel so as to improve the inputting accuracy and decrease the frequency of glancing at the keys.

Claims

1. A touch inductive key, which is a pressure activated key, comprising:

a key entity, and

a touch inductive panel on top of said key entity connecting to a response system, wherein

said key entity is the interface of inputting characters by the way of finger pressing;

said touch inductive panel activates said response system by detecting the finger touch.

2. The touch inductive key as set forth in claim 1, wherein said touch inductive panel is a resistance-type pressure inductive panel.

3. The touch inductive key as set forth in claim 1, wherein said touch inductive panel is a capacitance-type pressure inductive panel.

4. The touch inductive key as set forth in claim 1, wherein said touch inductive panel is a resistance-type pressure inductive panel.

5. The touch inductive key as set forth in claim 1, wherein said touch inductive panel is a capacitance-type pressure inductive panel.

6. The touch inductive key as set forth in claim 1, wherein said touch inductive panel composes a single inductive area that generates the same character no matter which part of said touch inductive panel touched by the finger.

7. The touch inductive key as set forth in claim 1, wherein said touch inductive panel divides the single inductive area into several sections so that, when the finger is placed on said touch inductive panel, it generate different characters or input different instructions depending upon which said section the finger placed.

8. The touch inductive key as set forth in claim 1, wherein the prompt of said response system is a voice prompt.

9. The touch inductive key as set forth in claim 1, wherein the prompt of said response system is switched on when the finger touches said touch inductive panel and switched off when the finger moves away from said touch inductive panel

10. The touch inductive key as set forth in claim 1, wherein said response system is a monitor displayed prompt.

11. The touch inductive key as set forth in claim 10, wherein said monitor displayed prompt is to generate a partial on-screen keyboard on the default location of said monitor and the character of the pressed key is shown in special color or diagrammatically marked.

12. The touch inductive key as set forth in claim 10, wherein said monitor displayed prompt is to generate a partial on-screen keyboard adjacent to the character of the pressed key near the cursor of inputted character.

13. The touch inductive key as set forth in claim 10, wherein said monitor displayed prompt is to generate an on-screen keyboard on the default location of said monitor and the character of the pressed key is shown in special color or diagrammatically marked.

14. The touch inductive key as set forth in claim 13, wherein there is a block on top of said on-screen keyboard to display the character just inputted.
