THREE DIMENSIONAL INPUT DEVICE USING GEO-MAGNETIC SENSOR AND DATA PROCESSING METHOD THEREFOR

摘要

The present invention relates to a three-dimensional position information input device using a three-axis geomagnetic sensor. The present invention displacement of the device for the peripheral magnetic field according to the movement of the geomagnetic sensor module, the apparatus for detecting an ambient magnetic field provided with a driver for driving the three-axis geomagnetic sensor as the geomagnetic sensor from the output which changes in the geomagnetic sensor It provides three-dimensional position information input device comprising a microprocessor and a communication module for transmitting to the peripheral device the calculated displacement angle information for calculating an angle. According to the invention, it is not possible to measure the accurate position information than in other situation in which the magnetic field source is present other than the magnetic field.
