Abstract

A method of controlling a portable device according to one embodiment of the present specification may be able to selectively activate the functions of a multifunctional control button. The method of controlling the portable device may include the steps of sensing a first control input for a control button configured to perform a fingerprint recognition function and a control input detection function, recognizing a fingerprint of the first control input by activating the fingerprint recognition function, if the fingerprint recognition function is activated, deactivating the control input detection function, and if the activated fingerprint recognition function is terminated, activating the control input detection function.

Claims

1-20. -20. (canceled)

21. A portable device, comprising:

a display unit configured to display an execution screen of an application and a home screen of the portable device;

a control button configured to receive a control input including a fingerprint input and a push input; and

a controller configured to;

execute a first execution function corresponding to the fingerprint input and a second execution function corresponding to the push input, wherein the first execution function is a security authentication for the application using the received fingerprint input and the second execution function is a transition from the execution screen of the application to the home screen,

receive a first control input when the execution screen of the application is displayed,

recognize a first fingerprint input of the first control input by activating a fingerprint recognition function, wherein a push input detection function is deactivated for avoiding detection of a first push input of the first control input while the fingerprint recognition function is activated,

execute the first execution function, wherein the first execution function is the security authentication for the application using the recognized first fingerprint input,

activate the deactivated push input detection function when the first execution function is terminated, even though the security authentication is failed,

receive a second push input of a second control input which is input after the first control input is terminated, the second control input including the second push input and a second fingerprint input, and

display the home screen of the portable device by executing the second execution function corresponding to the second push input of the second control input,

wherein the second execution function is not associated with the second fingerprint input of the second control input, and the second fingerprint input is not utilized in the second execution function.

22. The portable device of claim 21, wherein the controller is further configured to:

if the first control input is maintained when the push input detection function is activated,

measure a control input time of the first push input of the first control input using the push input detection function, and

execute the second execution function when the control input time is equal to or smaller than a first threshold time.

23. The portable device of claim 22, wherein the control input time is measured from a time when the fingerprint recognition function is terminated.

24. The portable device of claim 21, wherein the controller is further configured to:

if the first control input is maintained when the push input detection function is activated,

measure a control input time of the first push input of the first control input using the push input detection function, and

execute a third execution function when the control input time is greater than a first threshold time.

25. The portable device of claim 24, wherein the control input time is measured from a time when the fingerprint recognition function is terminated.

26. The portable device of claim 24, wherein the third execution function is configured to execute a voice recognition service of the portable device.

27. The portable device of claim 21, wherein the push input detection function detects a press for the control button as the push input.

28. The portable device of claim 21, wherein if the fingerprint recognition function is activated, the controller is further configured not to execute the second execution function even though the first push input of the first control input for the control button is received.

29. The portable device of claim 28, wherein if the fingerprint recognition function is activated, the controller is further configured to display a soft button corresponding to the second execution function in the display unit.

30. The portable device of claim 29, wherein if a third control input is detected on the displayed soft button, the controller is further configured to execute the second execution function.

31. The portable device of claim 21, wherein the fingerprint recognition function and the push input detection function are performed by two sensors included in the control button, respectively.

32. The portable device of claim 21, wherein the fingerprint recognition function and the push input detection function are performed by a single sensor included in the control button.

33. The portable device of claim 21, wherein the push input detection function is executed using at least one of a push button, a detection switch, a resistive touch screen, and a capacitive touch screen.

34. The portable device of claim 21, wherein if a recognition for the first fingerprint input of the first control input is completed or if the first fingerprint input of the first control input is not recognized for more than a second threshold time, the fingerprint recognition function is configured to be terminated.

35. The portable device of claim 21, wherein the control button comprises at least one of an ultrasonic sensor, a capacitance sensor, and an image sensor, and

wherein the fingerprint recognition function is configured to recognize the fingerprint of the first control input using at least one of the ultrasonic sensor, the capacitance sensor, and the image sensor.

36. The portable device of claim 21, wherein the controller is further configured to compare the recognized first fingerprint input of the first control input with reference fingerprint data stored in the portable device.

37. The portable device of claim 21, further comprising:

a network unit,

wherein the controller is further configured to compare the recognized first fingerprint input of the first control input with reference fingerprint data stored in an external server.

38. The portable device of claim 21, wherein if the portable device is locked, the controller is further configured to execute a voice recognition service of the portable device when the first control input for the control button is received.

39. The portable device of claim 21, wherein the portable device corresponds to a smartphone, a smart pad, a music player, a tablet computer, or a note book computer.

40. A method for controlling a portable device, the method comprising:

receiving a first control input when an execution screen of an application is displayed, wherein the first control input includes a first fingerprint input and a first push input;

recognizing the first fingerprint input of the first control input by activating a fingerprint recognition function, wherein a push input detection function is deactivated for avoiding detection of the first push input of the first control input while the fingerprint recognition function is activated;

executing a first execution function, wherein the first execution function is a security authentication for the application using the recognized first fingerprint input;

activating the deactivated push input detection function when the first execution function is terminated, even though the security authentication is failed;
