User dependent interface based on facial expression

This study is about the feasibility test of calibration and customizing method based on channel selection according to task and user dependent factors using multi-channeled MES device. Simple threshold methods were applied to evaluate the activation of each channel. Generally, interface utilizing biological signals has been known for its instability and complexity of the system, however, by choosing proper channels figuring out user´s intention and utilizing the channels as command signals, its system can be simple and stabilized.
