摘要:
Coordinates input apparatus and method which can accurately calculate a coordinate position by two vibration sensors are provided. The occurrence of a vibration of an input pen is controlled by at least two kinds of forms. At least two vibration sensors each for detecting the vibration from the input pen are provided. On the basis of the time until the vibration of each form arrives every vibration sensor, the distance from the input position of the input pen is calculated every vibration of each form. A difference between the distances calculated every vibration of each form which is calculated is calculated every vibration sensor.
