System, method for controlling user terminal using magnetic field, user terminal comprising the same

#This application claims priority of Korean Patent Application No. 10-2012-0107420, filed on Sep. 26, 2012, in the KIPO (Korean Intellectual Property Office), the disclosure of which is incorporated herein by reference in its entirety.

#The present disclosure relates to a system and method for controlling a user terminal using a magnetic field, and a user terminal comprising the same.

#With the development of information and communication technologies, studies have been conducted on various types of interaction methods between human and machine. Among them, an effective input means for a user terminal has been developed. For example, a capacitive touch screen being widely used these days has an advantage of determining whether an input is received through a proximity contact between an input means such as a human finger and the touch screen and executing a command conveniently using the finger, but has a limitation in that only two input activities of a user, that is, a touch and a release, are acceptable, and a disadvantage of limited haptic representations transmittable to the user due to a flat shape and an issue of finger occlusion occurring frequently during interaction with the user due to a relatively small size. To relieve these problems, many researchers have been studying interaction methods through an object such as a stylus pen.

#The above and other objects, features and advantages of the present disclosure will become apparent from the following description of certain exemplary embodiments given in conjunction with the accompanying drawings, in which:

#FIG. 1 is a schematic diagram illustrating a system for controlling a user terminal according to an exemplary embodiment;

#FIG. 2 is a cross-sectional view illustrating a pen as an object according to an exemplary embodiment;

#Hereinafter, a method and apparatus for controlling a user terminal based on a magnetic field according to exemplary embodiments will be described in detail with reference to the accompanying drawings.

#The following embodiments are provided to assist in a comprehensive understanding of the present disclosure, and not intended to limit the scope of this disclosure. Accordingly, equivalents performing the same function as the present disclosure will fall the scope of the present disclosure.

#Various parts or elements in the drawings are designated by reference numerals, and the same drawing reference numerals are used for the same elements even in different drawings. Also, in the following description, well-known functions or constructions are not described in detail since they would obscure the present disclosure with unnecessary detail.
