## Abstract

The present disclosure relates to a method of controlling a portable device using an electric pen, and a portable device thereof, and more particularly, to a method of controlling a portable device using an electric pen capable of controlling the portable device based on an interrupt event generated by a manipulation of the electric pen, and a portable device thereof. The method includes controlling a portable device using an electric pen, including sensing an interrupt event by manipulation of the electric pen positioned in a area within a sensible distance of the electric pen, sensing separation of the electric pen from the area within the sensible distance, and performing a control operation of the portable device in response to the separation.

## Claims

### Claim 1

A method of controlling a portable device using an electric pen, the method comprising:
sensing an interrupt event by manipulation of the electric pen positioned in an area within a sensible distance of the electric pen;
sensing separation of the electric pen from the area within the sensible distance; and
performing a control operation of the portable device in response to the separation.

### Claim 2 (depends on 1)

The method of claim 1, wherein the sensing of the interrupt event comprises:
sensing one of: a touch and hovering operation of the electric pen; and
sensing the interrupt event by the manipulation of the electric pen while one of: the touch and the hovering operation is sensed.

### Claim 3 (depends on 2)

The method of claim 2, wherein the one of: the sensing of the touch and the hovering operation comprises:
determining whether there is a control operation corresponding to the one of: the touch and the hovering operation; and
in response to the determination of a corresponding control operation, performing the control operation.

### Claim 4 (depends on 1)

The method of claim 1, wherein the sensing of the interrupt event comprises:
sensing a change of at least one of an electric signal and a magnetic signal by one of: the touch and the hovering operation of the electric pen; and
sensing the interrupt event by a change of a frequency of at least one of the electric signal and the magnetic signal.

### Claim 5 (depends on 4)

The method of claim 4, wherein the change of the frequency occurs by a manipulation of at least one of a button, a wheel, a dial and a switch of the electric pen.

### Claim 6 (depends on 1)

The method of claim 1, wherein the sensing of the interrupt event comprises:
receiving a wireless signal including interrupt information from the electric pen; and
sensing the interrupt event based on the interrupt information.

### Claim 7 (depends on 1)

The method of claim 1, wherein the sensing of the interrupt event comprises:
sensing a use input for generating an interrupt event; and
sensing the interrupt event based on the user input.

### Claim 8 (depends on 1)

The method of claim 1, wherein the performing of the control operation comprises:
determining whether a preset time has passed after the separation of the electric pen; and
in response to the passed preset time, performing the control operation.

### Claim 9 (depends on 1)

The method of claim 1, wherein the performing of the control operation comprises:
terminating an application under operation; and
displaying a standby screen or a home screen.

### Claim 10 (depends on 1)

The method of claim 1, wherein the performing of the control operation comprises:
entering a locking mode; and
displaying a locking screen as the portable device enters the locking mode.

### Claim 11 (depends on 1)

The method of claim 1, wherein the performing of the control operation comprises:
storing or temporarily storing a working state of an application under operation.

### Claim 12 (depends on 1)

The method of claim 1, wherein the performing of the control operation comprises:
turning off a power of at least one of components of the portable device except an input sensing unit for sensing the electric pen.

### Claim 13 (depends on 12)

The method of claim 12, further comprising:
sensing entrance of the electric pen into the area within the sensible distance by the input sensing unit; and
turning on a power of at least one of components that had power turned off.

### Claim 14

A portable device comprising:
a display unit configured to display information;
an input sensing unit configured to sense an input of an electric pen on the information, the input including at least one of:
an entrance of the electric pen into an area within a sensible distance,
an interrupt event by a manipulation of the electric pen positioned in the area within the sensible distance, and
a separation of the electric pen from the area within the sensible distance.

### Claim 15 (depends on 14)

The portable device of claim 14, wherein the input sensing unit is further configured to sense a frequency change of at least one of an electric signal and a magnetic signal by one of: a touch and a hovering operation of the electric pen, and to sense the interrupt event by a frequency change of at least one of the electric signal and the magnetic signal.

### Claim 16 (depends on 16)

The portable device of claim 16, wherein the frequency change occurs by a manipulation of at least one of a button, a wheel, a dial and a switch of the electric pen.

### Claim 17 (depends on 14)

The portable device of claim 14, further comprising:
a communication unit configured to transmit and receive a wireless signal with the electric pen,
wherein, the controller is configured to: in response to receiving a wireless signal including interrupt information through the communication unit, sense the interrupt event based on the interrupt information.

### Claim 18 (depends on 14)

The portable device of claim 14, further comprising:
an input unit configured to sense a user input for generating an interrupt event,
wherein the controller is further configured to sense the interrupt event based on the user input.

### Claim 19 (depends on 14)

The portable device of claim 14, wherein the controller is configured to perform at least one of:
an operation of controlling the display unit to terminate an application under operation, and
display at least one of a standby screen and a home screen,
an operation of entering a locking mode, and
an operation of at least one of storing and temporarily storing a working state of the application under operation.

### Claim 20 (depends on 14)

The portable device of claim 14, wherein the controller is further configured to:
turn off at least one of components of the portable device except the input sensing unit, and
in response to a sensing a re-entrance of the electric pen into the area within the sensible distance, turn on a power of at least one of components that had power turned off.
