The Electrooculogram (EOG) is one of important bio signals. The EOG is useful for many applications such as some disease analysis or assistive application for some type of disability persons. This paper proposes a new method identifying two eye movements, which are clockwise and counter-clockwise eye rotation movements using impulse response of the Finite Impulse Response (FIR) system characterizing EOGs between two channels. The proposed method consists of the three main processes: 1) EOG signal acquisition, 2) Fourier series approximation of EOG waveform, 3) the feature extraction using impulse response of FIR system characterizing EOGs between two channels. The experimental results show that the proposed method is useful for identifying two eye movements (clockwise and counter-clockwise).
