In this paper, as the fusion study of LED lighting and sound based on the emotion, we conducted this study for extraction of Emotional Factor based on LED lighting and sound. The sound received from a microphone through FFT and FIR filter extracts only useful frequency band. And the Emotional Factor possible to be extracted via a Moving Average Filter send data to serial output port. The Moving Average Filter takes an average at time axis. Also it is easy to extract Emotion Factor to maintain overall tendency of the data which strong at noise. We demonstrated the usefulness of the proposed system through the experiment.
