Abstract

The present invention relates to an electric apparatus which determines user input using a magnetic field sensor, wherein the electric apparatus accurately determines user input using a mobile communication terminal having a magnetic field sensor and performs an operation, such as control or the like, based on the determination. The electric apparatus which determines user input using a magnetic field sensor according to the present invention comprises: at least one magnetic field sensor for sensing a magnetic field of an external object having n degrees of freedom and a magnetic field generating unit and generating a limited m-dimensional magnetic field vector; and a control unit for storing physical advance information regarding the motion of the external object, and determining information on the displacement and rotation of the external object based on the limited m-dimensional magnetic field vector and the physical advance information.

Description

technical field [0001] The present invention relates to an electric device, and more particularly, to an electric device for determining a user input by using a mobile communication terminal provided with a magnetometer for accurately determining the user input and performing a control function in response to the determination result and the like. Background technique [0002] Since the PC era, the mouse has been used as a 2D or 2-DOF (degree of freedom) device for inputting motion in both directions of the x-axis and y-axis. Therefore, US Patent No. 7,217,448 of Logitech Inc. discloses the implementation of a 3-DOF configuration that uses two optical sensors to increase the resolution of the mouse and recognize the rotation angle r of the mouse. Later, laptop computers with touch pads were introduced and widely used so that the flat screen of the computer could be turned off when a finger was tapped on the screen. With the advent of tablet PCs and smartphones, such touchpa...
