Abstract
A method of controlling a portable device based on variation of a magnetic field by a detachable pen attached to the portable device and a portable device thereof is provided. The method includes detecting variation of a magnetic field due to at least one of an attaching, a detaching, and a rotation of the pen, determining whether there is a control operation corresponding to the variation of the magnetic field, and performing the control operation corresponding to the variation of the magnetic field when there is the control operation.
Claims20
A method of controlling a portable device to which a pen is detachably attached, the method comprising:
- detecting variation of a magnetic field due to at least one of an attaching, a detaching, and a rotation of the pen;
- determining whether a control operation corresponding to the variation of the magnetic field exists;
- and
- performing the control operation, when the control operation corresponding to the variation of the magnetic field exists.
A portable device to which a pen is detachably attached, the portable device comprising:
- a hole in which the pen is detachably attached and which is formed to allow the pen to be rotated when the pen is in an attached state;
- a sensor installed in proximity to the hole to detect variation of a magnetic field by the pen;
- and
- a controller for determining whether a control operation corresponding to the variation of the magnetic field detected by the sensor exists, and for performing the control operation when the control operation corresponding to the variation of the magnetic field exists.
