INPUT MEAN FOR USER TERMINAL USING MAGNETIC FIELD

摘要

Disclosed are a magnetic field-based user terminal input means, a user terminal, and a user terminal input system. The present invention includes an input means which has a magnet and is capable of plane free movement according to an externally applied force; a magnetic sensor which senses a magnetic field generated from the input means; a reference position setting unit which sets and stores a plurality of reference positions based on magnetic field sensing values at a plurality of points of the input means physically moving on any plane in a reference setting mode; and an input means position determining unit which compares the reference positions stored in the reference position setting unit in a state determination mode and the magnetic sensing value sensed by the magnetic sensor and determines the position of the input means corresponding to the magnetic sensing value.
