INPUT MEAN FOR USER TERMINAL USING MAGNETIC FIELD

摘要

The present invention discloses a magnetic field based user terminal input means, a user terminal and a user terminal input system. The present invention comprises an input means including a magnet and capable of moving linearly by being guided by housing according to power applied from outside; a magnetic sensor for sensing a magnetic field generated from the input means; a standard value configuration part for configuring magnetic field sensing values of at least two points as standard values at a linear path where the input means moves physically in a standard configuration mode for storing; and an input means position determination part for comparing the standard value stored at the standard value configuration part with a magnetic sensing value sensed by the magnetic sensor for determining the position of the input means corresponding to the magnetic sensing value.
