For the severely disabled people who are paralyzed in the lower part from the neck, eye-control input device takes an important role as computer input support interface as other tongue, EEG and EMG based input method. The eye input device has an advance in more direct operation feel than EEG.EMG stepping cursor moving input method. On the other hand, eye input device is still costly comparing with the other conventional input device. This study aims at developing a low-cost mouse control interface with an iris detecting camera attached goggle. This study consists of iris tracking performance partand mouse control algorithm part. Here, we adopted the adequate morphological operation and ellipse fitting for steady iris tracking. To achieve robust operation under head motion, this paper proposes the relative displacement mouse driving. In the mouse driving experiment, the optimal gain between iris and mouse step is derived as 2.0 for smooth input operation.
