Abstract: In a position detector having two sensors, a first sensor detects a position indicated by a first indicator by electromagnetic induction and a second sensor detects a position indicated by a second indicator by a detection method other than electromagnetic induction. The position detector reduces adverse effects of the transmission signal supplied to the second sensor on the electromagnetic induction position detection circuit. The position indication state of the first and second indicators is determined based on a signal output from the first sensor according to the position indication by the first indicator on the first sensor and a signal output from the second sensor according to the position indication by the second indicator on the second sensor. According to the determination results of the position indication state, the level of the transmission signal provided to the second sensor to detect the position indication by the second indicator is controlled.

Abstract: A method performed by a pen or a pen detection apparatus that detects the pen, the method includes: acquiring a pen pressure level according to a force applied to a pen nib of the pen; generating a pen-down event or a pen-up event based on a result of comparing the pen pressure level and a pen pressure determination threshold; acquiring a proximity value indicating a positional relationship between the pen and the pen detection apparatus from a proximity detector provided on one of the pen and the pen detection apparatus; and updating the pen pressure determination threshold based on the pen pressure level when the proximity value indicates that the positional relationship between the pen and the pen detection apparatus satisfies a predetermined relationship.
