The main unit amplifies the received direction signal and filters the noise from the amplified direction signal (S520).

The main unit analyzes the pattern of the direction signal from which the noise is filtered (S430). For example, the main body apparatus analyzes the pattern of the direction signal based on the direction information and time series information included in the direction signal (S530).

The main body apparatus compares the analyzed pattern with a previously stored pattern and determines whether the input direction signal is a normal signal according to whether there is a matching pattern (S540).

If there is a matching pattern, the main unit determines the input direction signal as a normal signal. The main body device, which determines the input direction signal as a normal signal, recognizes the content input by the user through the analyzed pattern, and stores the recognized content or utilizes the same in an application program (S550).

If there is no matching pattern, the main unit determines the input direction signal as an abnormal signal and analyzes the pattern of the next direction signal received.
