Abstract

Provided are a mobile terminal and a control method therefor. The mobile terminal includes: a touchscreen disposed on one side of a main body of the terminal; a push key mounted on the main body to receive a push input; and a controller that displays virtual keys associated with the settings or control of the terminal on the touchscreen when the push key is pushed, and executes functions associated with a speech recognition mode when a set period of time elapses without at least one touch input on the virtual keys being sensed.

First claim

1 . A mobile terminal comprising:
a touchscreen disposed on one side of a main body of the terminal; a push key mounted on the main body to receive a push input; and a controller that displays virtual keys associated with the settings or control of the terminal on the touchscreen when the push key is pushed, and executes functions associated with a speech recognition mode when a set period of time elapses without at least one touch input on the virtual keys being sensed.

2 . The mobile terminal of claim 1 , wherein the controller outputs guidance information for the speech recognition mode if a first period of time elapses without the touch input being sensed, and executes the speech recognition mode if a second period of time elapses after the output of the guidance information.

3 . The mobile terminal of claim 2 , wherein the guidance information is output in audio format through audio output parts on the main body.

4 . The mobile terminal of claim 2 , wherein the controller performs a control operation for deactivating the touchscreen when the speech recognition mode is executed.

5 . The mobile terminal of claim 2 , wherein, if the push key is pushed while the speech recognition mode is on, the speech recognition mode is finished, and the virtual keys are displayed again on the touchscreen.

6 . The mobile terminal of claim 2 , wherein, if the push key is pushed before the elapse of the first period of time, the virtual keys associated with the settings and control of the terminal disappear.

7 . The mobile terminal of claim 1 , wherein the speech recognition mode comprises first and second speech recognition modes in which different processing results are output for the same voice command entered through a microphone on the main body, and
wherein if the set period of time elapses without at least one touch input on the virtual keys being sensed, a command is given to execute the first speech recognition mode.

8 . The mobile terminal of claim 7 , wherein the second speech recognition mode is executed by touching or pushing a home key on the terminal in a preset pattern.

9 . The mobile terminal of claim 7 , wherein the processing result for the first speech recognition mode is output through the audio output parts on the main body, and the processing result for the second speech recognition mode is output through the touchscreen.

10 . The mobile terminal of claim 7 , wherein the user selects whether to execute the first speech recognition mode.

11 . The mobile terminal of claim 1 , wherein the controller asks for authentication information upon receiving a user request to execute a particular function in the speech recognition mode.

12 . The mobile terminal of claim 11 , wherein the authentication information is requested in a case where the lock function is enabled in the terminal.

13 . The mobile terminal of claim 11 , wherein the asking for authentication information is disabled in the speech recognition mode settings.

14 . The mobile terminal of claim 13 , wherein the particular function comprises at least either a Call function or a Read messages function, and
wherein once the asking for authentication information is disabled, at least either the Call function or the Read messages function is performed without authentication upon a request from the user, while the terminal is locked.

15 . The mobile terminal of claim 1 , wherein the controller checks whether the destination number is included in saved contacts, upon receiving a request from the user to make a call in the speech recognition mode.

16 . The mobile terminal of claim 15 , wherein, if a phone number to be called is entered by voice and the phone number is included in the contacts, the controller outputs a guide that asks the user to provide other information associated with the phone number.

17 . The mobile terminal of claim 1 , wherein, if the set period of time elapses without at least one touch input on the virtual keys being sensed, the speech recognition mode is executed, and
wherein if there is no voice command input from the user in the speech recognition mode, a phrase prompting the user to speak a voice command is output.

18 . The mobile terminal of claim 17 , wherein the phrase is displayed on the touchscreen and disappear when the voice command is recognized.

19 . The mobile terminal of claim 1 , wherein, if the set period of time elapses without at least one touch input on the virtual keys being sensed, the speech recognition mode is executed, and
wherein the speech recognition mode offers control functions associated with the turn on/off of alarms.

20 . The mobile terminal of claim 19 , wherein, if the user has multiple alarms set on the terminal, the alarms are turned off altogether when the user enters a voice command to turn off the alarms in the speech recognition mode.

21 . A mobile terminal comprising: a touchscreen;
audio output parts that output audio; a detector that detects an abnormal state of the touchscreen; and a controller that, if an abnormal state is detected, outputs guidance information on at least one function that allows for control of the terminal in the abnormal state through at least either the audio output parts or the touchscreen.

22 . The mobile terminal of claim 21 , wherein the detector detects an abnormal state of the touchscreen by sensing an impact or acceleration on the terminal or sensing information associated with the amount of electric current for controlling the touchscreen.

23 . The mobile terminal of claim 21 wherein, if an abnormal state is detected, the controller outputs guidance information associated with a speech recognition mode and receives the user's input about whether to execute the speech recognition mode.

24 . The mobile terminal of claim 21 , wherein, if an abnormal state is detected, the controller outputs guidance information associated with a change of a driving method of the touchscreen and receives the user's input about whether to change the driving method.

25 . The mobile terminal of claim 24 , wherein the touchscreen is divided into a plurality of areas, and upon detecting an abnormal state in some of these areas, the controller controls the touchscreen to display in the remaining area, apart from the area where the abnormal state is detected.
