Abstract
A mobile device and method for processing an acoustic signal are provided. The mobile device may calculate a position of an inputted touch and recognize a character from the calculated position. The mobile device may perform a function corresponding to the recognized character, or display the position of the touch.
Claims23
A mobile device for processing an acoustic signal, the device comprising:
- a sensing unit configured to sense an acoustic signal based on a touch inputted from a surface of the mobile device;
- an acoustic signal processing unit configured to perform signal processing on the sensed acoustic signal;
- an acoustic signal position determining unit configured to calculate a position of the inputted touch based on the signal-processed acoustic signal;
- and
- a character recognition unit configured to recognize a character from the calculated position.
A mobile device for processing an acoustic signal, the mobile device comprising:
- a sensing unit configured to sense an acoustic signal based on a touch event with respect to an object that is approximately in contact with the mobile device;
- an acoustic signal processing unit configured to perform signal processing on the sensed acoustic signal;
- an acoustic signal position determining unit configured to calculate a position generated by the touch event using the signal-processed acoustic signal;
- and
- a shape recognition unit configured to recognize the calculated position as a shape.
A method of processing an acoustic signal, the method comprising:
- sensing an acoustic signal based on a touch inputted from a surface of a mobile device;
- signal processing the sensed acoustic signal;
- calculating a position of the inputted touch based on the signal-processed acoustic signal;
- and
- executing a function based on the calculated position.
A computer-readable storage medium storing a program to process an acoustic signal, the storage medium comprising:
- sensing an acoustic signal based on a touch inputted from a surface of a mobile device;
- signal processing the sensed acoustic signal;
- calculating a position inputted by the touch based on the signal-processed acoustic signal;
- and
- executing a function based on the calculated position.
