Eye Based HCI with Moving Keyboard for Reducing Fatigue Effects

Moving keyboard utilized eye-based HCI: Human Computer Interaction is proposed for reducing physical and psychological fatigues. Fatigues occur as eye intention and gaze angle and direction is changed for selection of designated keys and are happened when users use eye-based HCI system for a long period depending on the number of gaze changes as well as traveling length of eye gaze position on the computer screen. This paper proposes eye-based HCI with moving keyboard layout which allow reducing fatigue effect. Only thing user has to do is just look at the center of the computer screen and four adjacent keys, right, left, up, and down keys. By using EEG: Electroencephalograph analyzer, a comparative study has been done between the proposed eye-based HCI with moving keyboard and the existing conventional eye-based HCI. Taking Event-Related Desynchronization (ERD) into account, users.fatigues are measured. The results show fatigue effects of the proposed HCI is smaller than that of the conventional HCI.
