Abstract
A method of compensating an error of an input device and an apparatus thereof. An electromagnetic induction pen including a coil for electromagnetic induction spaced apart from a nib of the pen is prepared. A sensor board is provided in the apparatus in which a voltage or current for electromagnetic induction of the electromagnetic induction pen output. A disposition state of the sensor board is determined. The voltage or the current is adjusted and provided to the sensor board formed according to a sensed rotation state of the sensor board or terminal in order to compensate for an error generated due to a distance between the nib and the coil. An error is compensated for by allowing coordinates according to the electromagnetic induction formed on the sensor board and varied with the rotation disposition state of the sensor board to correspond to a position of the nib.
