Abstract

An electronic device and method are provided. The electronic device includes an electromagnetic resonant panel, an electromagnetic controller configured to detect input values, which are induced in multiple locations of the electromagnetic resonant panel by at least one resonant circuit of an input pen, and a controller configured to detect a pen multi-input event based on the detected input values, and to control an operation corresponding to the detected pen multi-input event.

Claims

an electromagnetic resonant panel;

an electromagnetic controller configured to detect input values, which are induced in multiple locations of the electromagnetic resonant panel by at least one resonant circuit of an input pen; and

a controller configured to detect a pen multi-input event based on the detected input values, and to control an operation corresponding to the detected pen multi-input event.

2. The electronic device of claim 1, wherein the electromagnetic resonant panel forms a resonant signal of a predetermined frequency, and

wherein the electromagnetic controller detects input values, which are induced in multiple locations of the electromagnetic resonant panel by flux distribution of an electromagnetic field formed in the at least one resonant circuit of the input pen.

3. The electronic device of claim 1, wherein the electromagnetic resonant panel forms a resonant signal of a first frequency and a resonant signal of a second frequency, and

wherein the electromagnetic controller detects input values, which are induced in multiple locations of the electromagnetic resonant panel by flux distribution of an electromagnetic field, which is formed in a first resonance circuit of the input pen and coupled with a first frequency, and a second resonance circuit of the input pen and coupled with the second frequency.

4. The electronic device of claim 1, wherein the controller is configured to determine an input type of the pen multi-input event based on levels of a first input value and a second input value determined by an electromagnetic field formed between two ends of the at least one resonant circuit of the input pen.

5. The electronic device of claim 4, wherein the controller is configured to determine the input type as a first pen multi-input event, if both of the first input value and the second input value exceed a predetermined first level.

6. The electronic device of claim 4, wherein the controller is configured to determine the input type as a second pen multi-input event, if the first input value exceeds a predetermined first level and the second input value does not exceed the predetermined first level.

7. The electronic device of claim 1, wherein the pen multi-input event comprises a pen multi-input gesture and the controller is configured to control an operation corresponding to the pen multi-input gesture.

8. The electronic device of claim 7, wherein the operation corresponding to the pen multi-input gesture comprises:

an operation of enlarging data being displayed, if the pen multi-input gesture moves in a first direction; and

an operation of reducing data being displayed, if the pen multi-input gesture moves in a second direction being opposite to the first direction.

9. The electronic device of claim 7, wherein the operation corresponding to the pen multi-input gesture comprises:

an operation of determining and displaying a previous web page preceding a currently displayed web page, if the pen multi-input gesture moves in a first direction; and

an operation of determining and displaying a next web page following the currently displayed web page, if the pen multi-input gesture moves in a second direction being opposite to the first direction.

10. The electronic device of claim 7, wherein the operation corresponding to the pen multi-input gesture comprises:

an operation of handling a predetermined first key input, if the pen multi-input gesture moves in a direction of a first key; and

an operation of handling a predetermined second key input, if the pen multi-input gesture moves in a direction of a second key being different from the first key.

11. The electronic device of claim 7, wherein the operation corresponding to the pen multi-input gesture comprises an operation of deleting data that is input in a running application.

12. The electronic device of claim 7, wherein the operation corresponding to the pen multi-input gesture comprises an operation of transmitting messaging data including data that is input in a running application.

13. The electronic device of claim 1, wherein the controller is configured to turn off a display if the pen multi-input event occurs in a same area for a predetermined amount of time.

14. The electronic device of claim 13, wherein the controller is configured to control an operation of displaying a lock screen on the display, if the pen multi-input event is released.

15. The electronic device of claim 1, wherein the controller is configured to control:

an operation of storing running information and turning off the display, if the pen multi-input event occurs in a same area for a predetermined amount of time; and

display of the stored information on the display, if the pen multi-input event is released.

16. A method for handling a pen input, the method comprising:

providing a driving signal for an electromagnetic resonant panel;
