Abstract
Vibration is sensed as a signal by a vibration sensor and the signal level of the sensed signal is measured by an A/D converter. The distance between a position entered by a vibrating input pen and the vibration sensor is calculated and, on the basis of the calculated distance, input level information is obtained from the measured signal level by an arithmetic and control unit.
