A system, comprising: a sensor device comprising: a sensor configured to output a vibration datum representing a frequency spectrum by detecting a change in a state of a vibration in a first object when a second object touches the first object ; a holding section configured to hold, at a portion of the first object which is different from a portion where the second object touches, the sensor in a state where the vibration in the first object is transmitted; and a first communication section configured to transmit the single vibration datum detected by the sensor to an analyzing device which identifies a touch position where the second object touches the first object by analyzing the vibration datum; said analyzing device comprising: a storage section configured to store a vibration characteristic for each position in a position group set in a portion of the first object where the second object touches; a second communication section configured to receive a single vibration datum representing a frequency spectrum from the sensor device ; and an identification section configured to identify a touch position where the second object touches the first object by analyzing a vibration characteristic of the vibration datum with respect to the vibration characteristic for each position of the first object where the second object touches as one or a plurality of positions in the position group. a sensor configured to output a vibration datum representing a frequency spectrum by detecting a change in a state of a vibration in a first object when a second object touches the first object ; a holding section configured to hold, at a portion of the first object which is different from a portion where the second object touches, the sensor in a state where the vibration in the first object is transmitted; and a first communication section configured to transmit the single vibration datum detected by the sensor to an analyzing device which identifies a touch position where the second object touches the first object by analyzing the vibration datum; said analyzing device comprising: a storage section configured to store a vibration characteristic for each position in a position group set in a portion of the first object where the second object touches; a second communication section configured to receive a single vibration datum representing a frequency spectrum from the sensor device ; and an identification section configured to identify a touch position where the second object touches the first object by analyzing a vibration characteristic of the vibration datum with respect to the vibration characteristic for each position of the first object where the second object touches as one or a plurality of positions in the position group. a storage section configured to store a vibration characteristic for each position in a position group set in a portion of the first object where the second object touches; a second communication section configured to receive a single vibration datum representing a frequency spectrum from the sensor device ; and an identification section configured to identify a touch position where the second object touches the first object by analyzing a vibration characteristic of the vibration datum with respect to the vibration characteristic for each position of the first object where the second object touches as one or a plurality of positions in the position group. <EOS>
