Abstract

The present invention provides a mobile terminal and a control method using an intuitive gesture as an input to perform a function. Specifically, the present invention provides a mobile terminal including a sensing unit for sensing movement of the mobile terminal, a wireless communication unit for transmitting/receiving a radio signal to/from an external terminal and a control unit for sensing a distance from the mobile terminal to the external terminal based on the strength of the received radio signal, and performing a specific function when the sensed movement corresponds to specific movement and the sensed distance is within a specific range.

Claims

1. A mobile terminal, comprising:

a touchscreen configured to display information;

a sensing unit configured to sense motion of the mobile terminal;

a wireless communication unit configured to receive wireless signals; and

a controller configured to;

control the wireless communication unit to receive a wireless signal from an external terminal;

determine a distance from the mobile terminal to the external terminal based on strength of the received wireless signal;

perform a specific function when the sensed motion corresponds to a specific motion and the determined distance is within a specific range the specific function comprising;

controlling the touchscreen to display an execution screen of an application in response to sensing a first motion that includes rotating the mobile terminal from a first position to a second position; and

causing the external terminal to display an indicator related to the application in response to sensing a second motion that includes rotating the mobile terminal from the second position to the first position.

2. The mobile terminal of claim 1, wherein the controller is further configured to:

control the wireless communication unit to receive motion information related to the external terminal; and

perform the specific function only when the sensed motion and the received motion information correspond to the specific motion and the determined distance is within the specific range.

3. The mobile terminal of claim 1, further comprising a touchscreen wherein:

the sensing unit is further configured to sense a first direction faced by the touchscreen; and

the motion comprises rotating the touchscreen from the first direction to a second direction.

4. The mobile terminal of claim 3, wherein:

the first direction is a direction in which the touchscreen faces downward; and

the second direction is a direction in which the touchscreen faces upward.

5. The mobile terminal of claim 1, wherein the specific function further comprises controlling the touchscreen to switch from a deactivated state to an activated state.

6. The mobile terminal of claim 1, wherein the specific function further comprises disabling a security enabled application.

7. The mobile terminal of claim 1, wherein the specific function further comprises automatically entering login information to a webpage.

8. The mobile terminal of claim 1, further comprising a camera, wherein the specific function further comprises enabling a security attribute for a photo captured via the camera.

9. The mobile terminal of claim 1, wherein the specific function further comprises entering a mode for viewing a security enabled photo.

10. The mobile terminal of claim 1, wherein the specific function further comprises controlling the touchscreen to display a notification.

11. A method of controlling a mobile terminal, the method comprising:

determining motion of the mobile terminal;

receiving a wireless signal from an external terminal;

determining a distance from the mobile terminal to the external terminal based on strength of the received wireless signal;

performing a specific function when the sensed motion corresponds to a specific motion and the determined distance is within a specific range the specific function comprising;

displaying a execution screen of an application in response to sensing a first motion that includes rotating the mobile terminal from a first position to a second position; and

causing the external terminal to display an indicator related to the application in response to sensing a second motion that includes rotating the mobile terminal from the second position to the first position.

12. The method of claim 11, further comprising:

receiving motion information related to the external terminal; and

performing the specific function only when the sensed motion and the received motion information correspond to the specific motion and the determined distance is within the specific range.

13. The method of claim 11, further comprising sensing a first direction faced by a touchscreen of the mobile terminal, wherein the motion comprises rotating the touchscreen from the first direction to a second direction.

14. The method of claim 13, wherein:

the first direction is a direction in which the touchscreen faces downward; and

the second direction is a direction in which the touchscreen faces upward.

15. The method of claim 11, wherein the specific function further comprises switching a touchscreen of the mobile terminal from a deactivated state to an activated state.

16. The method of claim 11, wherein the specific function further comprises disabling a security enabled application.

17. The method of claim 11, wherein the specific function further comprises automatically entering information to a webpage.
