Abstract

A method for controlling an operation of a portable terminal using a microphone includes detecting an operation mode of the portable terminal and driving an audio recognition mode according to the detected operation mode to activate the microphone, converting a signal, inputted through the microphone, into digital data and detecting audio characteristics from the digital data to extract audio analysis data for recognition of a type of the input signal, and determining whether there is UI setting information corresponding to the extracted audio analysis data type and performing a relevant function of the UI setting information.

Claims

1. A method for controlling an operation of a portable terminal using a microphone, comprising:

detecting an operation mode of the portable terminal and driving an audio recognition mode according to the detected operation mode to activate the microphone;

converting a contact or motion signal generated on or near the microphone into digital data and detecting audio characteristics from the converted digital data to extract audio analysis data for recognition of a type of the input signal; and

determining whether there is User Interface (UI) setting information corresponding to the extracted audio analysis data type, and performing a relevant function specified in the UI setting information according to the determination outcome.

2. The method of claim 1, wherein the audio analysis data is obtained by eliminating an interference noise from the digital data and amplifying the resulting data.

3. The method of claim 1, wherein the signal detected by the microphone comprises an audio signal that is generated by a pointing action of tap, drag, or click caused by an action of a user on or around the microphone.

4. The method of claim 1, wherein the UI setting information is a menu execution command predetermined depending on the characteristics of the audio analysis data.

5. The method of claim 4, wherein the predetermined menu execution command is a default menu predetermined in an initial operation of the portable terminal and is selectively reset for each type of a signal inputted from the microphone by the user.

6. The method of claim 1, further comprising allocating a new UI setting information to the extracted audio analysis data type if there is no UI setting information corresponding to the extracted audio analysis data type.

7. An apparatus for controlling an operation of a portable terminal using a microphone, comprising:

a microphone;

an analog/digital (A/D) converter converting a contact or motion signal, inputted from the microphone, into digital data;

a memory storing a menu execution command predetermined for each User Interface (UI) setting information type;

an audio data processor detecting the audio characteristics of the digital data outputted from the A/D converter and extracting audio analysis data from the detected data to recognize a type of the input signal; and

a controller detecting an operation mode of the portable terminal, driving an audio recognition mode according to the detected operation mode to activate the microphone, searching the memory to determine whether there is UI setting information corresponding to the extracted audio analysis data type, and performing a relevant function of the UI setting information on the basis of the information stored in the memory.

8. The apparatus of claim 7, wherein if there is no UI setting information corresponding to the extracted audio analysis data type, the controller allocates a new UI setting information to the extracted audio analysis data type.

9. The apparatus of claim 7, wherein the audio data processor comprises:

a noise eliminator eliminating an interference noise form the digital data outputted from the A/D converter; and

an amplifier amplifying the resulting signal obtained by the noise elimination,

wherein the noise eliminator and the amplifier are used to detect the audio characteristics to extract the audio analysis data.

10. The apparatus of claim 7, wherein the UI setting information is a menu execution command predetermined depending on the characteristics of the audio analysis data.

11. The apparatus of claim 7, wherein the signal inputted from the microphone is an audio signal that is generated by an action of tap, drag, click or scratch caused by an action of a user touching the microphone.

12. The apparatus of claim 7, wherein the audio analysis data is to be recognized as tap, drag, click, or scratch.

13. A method for controlling an operation of a portable terminal using a microphone, comprising:

detecting a contact or motion signal via the microphone and converting the detected signal into digital data;

determining a type of input signal corresponding to the converted digital data;

comparing the determined input signal type to a predetermined table having a plurality of User Interface (UI) setting information; and

if there is a match between the determined input signal type to one of the UI setting information, performing a corresponding function specified in the matched UI setting information.

14. The method of claim 13, wherein the signal detected by the microphone comprises an audio signal that is generated by a pointing action including a tap, drag, or click motion by a user.

15. The method of claim 13, wherein, if there is no match, storing a new UI setting information correspond to the extracted audio analysis data.
