Abstract

A glasses-type terminal including a main body configured to be worn as glasses on a user'"'"'s head; a first microphone configured to detect a vibration signal through a skull portion of the user in which a voice being input propagates through the skull portion of the user; a second microphone configured to detect a voice signal in which the voice being input propagates over the air; a memory configured to store a pre-registered vibration signal and a pre-registered voice signal corresponding to a pre-registered voice; and a controller configured to switch a locked state to an unlocked state when the vibration signal detected through the first microphone is matched to the pre-registered vibration signal and the voice signal detected through the second microphone is matched to the pre-registered voice signal.

Claims

1. A glasses-type terminal comprising:

a memory configured to store a pre-registered vibration signal and a pre-registered voice signal corresponding to a pre-registered voice; and

a controller configured to;

switch a locked state to an unlocked state when the vibration signal detected through the first microphone is matched to the pre-registered vibration signal and the voice signal detected through the second microphone is matched to the pre-registered voice signal.

2. The glasses-type terminal of claim 1, further comprising:

a display unit,

wherein the controller is further configured to;

sense that the main body is being worn as glasses,

display image objects indicating operational states of the first and second microphones on a locked screen on the display unit, and

detect the vibration signal of the voice input through the first microphone and the voice signal of the voice input through the second microphone.

3. The glasses-type terminal of claim 2, wherein the controller is further configured to:

activate the first microphone and the second microphone, when the main body is sensed as being worn as glasses, and

display a first image object indicating the operational state of the activated first microphone and a second image object indicating the operational state of the activated second microphone.

4. The glasses-type terminal of claim 3, wherein the controller is further configured to:

display differently the first image object according to a result of matching the vibration signal detected through the first microphone to the pre-registered vibration signal, and

display differently the second image object according to a result of matching the voice signal detected through the second microphone to the pre-registered voice signal.

5. The glasses-type terminal of claim 1, wherein the first microphone includes a bone conduction pickup element and is arranged to correspond to at least one of the user'"'"'s left and right ears, and

wherein the second microphone is configured to be removably mounted on one frame of the main body using a connector and thus combined with the main body.

6. The glasses-type terminal of claim 5, wherein the first microphone is integrally combined with a speaker, and

wherein the controller is further configured to turn the speaker off, when the first microphone is in an ON state, and turn off the first microphone, when the speaker is in the ON state.

7. The glasses-type terminal of claim 2, wherein the controller is further configured to:

execute a voice registration mode based on a predetermined input signal,

display text on the display unit,

determine whether a voice corresponding to the displayed text input through the first and second microphones is consistent with pronunciation of the displayed text, and

register the voice as a vibration signal input through the first microphone and a voice signal input through the second microphone, based on a result of the determination.

8. The glasses-type terminal of claim 7, wherein in the voice registration mode, the controller is further configured to:

register a vibration signal and a voice signal for a first user and a second user, and

differently apply an application range of the unlocked state for the first user differently than the application range of the unlocked state for the second user.

9. The glasses-type terminal of claim 1, wherein the controller is further configured to:

output a first alarm, if the vibration signal detected through the first microphone is matched to the pre-registered vibration signal, and

output a second alarm, if the voice signal detected through the second microphone is matched to the pre-registered voice signal.

10. The glasses-type terminal of claim 1, wherein when any one of the vibration signal and the voice signal of the voice input through the first and second microphones fails to be matched to one of the pre-registered vibration signal and the pre-registered voice signal, the controller is further configured to apply the unlocked state to some predetermined applications and maintain the locked states of other applications.

11. The glasses-type terminal of claim 2, wherein when the vibration signal and the voice signal of the voice input though the first and second microphones fail to be matched to the pre-registered vibration signal and the pre-registered voice signal, respectively, the controller is further configured to maintain the locked state and display information indicating the failure in the match.

12. The glasses-type terminal of claim 2, wherein if the vibration signal and the voice signal of the voice input through the first and second microphones fail to be matched to the pre-registered vibration signal and the pre-registered voice signal, respectively, the controller is further configured to display information requesting a user'"'"'s response for determining whether or not locked states of some predetermined applications switch to the unlocked states.

13. The glasses-type terminal of claim 12, wherein based on the user'"'"'s response corresponding to the information being displayed, the controller is further configured recognize a voice of the third party is recognized as the pre-registered voice, during a period of time in which a predetermined condition is satisfied.

14. The glasses-type terminal of claim 2, wherein when the voice input through the first and second microphones is matched to a voice command for causing the locked state to switch to the unlocked state, and the pre-registered vibration signal and the pre-registered voice signal of the voice being input fail to be matched to the vibration signal and the voice signal, respectively, corresponding to the pre-registered voice, the controller is further configured to apply the unlocked state to some predetermined applications and outputs on the locked screen icons indicating the some predetermined applications in the unlocked state.

15. The glasses-type terminal of claim 1, wherein if any one of the vibration signal and the voice signal of the voice input through the first and second microphones fails to be matched to at least one of the pre-registered vibration signal and the pre-registered voice signal a predetermined number of times or more, the controller is further configured to provide a different input method of unlocking the locked state.

16. The glasses-type terminal of claim 15, wherein if the locked state switches to the unlocked state according to an input using the different input method, the controller is further configured to switch the unlocked state back to the locked state when a predetermined time elapses.
