| 20100281984 | METHOD AND APPARATUS FOR MEASURING POSITION OF THE OBJECT USING MICROPHONE - Provided is a method and device for measuring a position of an ultrasonic generating device for generating ultra-sonic signals, and inputting information by using position measurement values of the ultrasonic generating device. Accordingly, a plurality of broadband microphones that can be used as general microphones provided to an electronic device are used in a case where information is input by using an ultrasonic generating device. In this case, a position of the ultrasonic generating device is measured by extracting an ultrasonic signal generated by the ultrasonic generating device from signals received by the broadband microphones, and information is input by using the position of the ultrasonic generating device and a trajectory of the moving ultra-sonic generating device. Therefore, the inconvenience of a related art in that a plurality of ultrasonic sensors prepared additionally have to be mounted to an electronic device or a frame to which the plurality of the ultrasonic sensors are mounted has to be connected whenever information is input by using ultrasonic signals, particularly, a problem in that the plurality of ultrasonic sensors have to be prepared to perform information inputting using the ultrasonic waves by a portable electronic device, can be solved. | 11-11-2010 |
