In this paper, we constructed an eye-movement HCI platform
for several applications. Fig. 1 illustrated the eye-movement HCI
platform architecture. The eye-movement coils are the electromagnetic
fields that received signal between 50 lV and 3500 lV with a
frequency range of about dc-100 Hz. Eye-movement signals needs
to be adjusted/normalized by signal amplifier, adders and filters.
The filters eliminate the effects due to other bio-potentials, such
as saccadic/blink over to the EOG signal. After that, the EOG signal
is then converted to digital signal and then transmitted to the
computer. The application control component will deal with the
eye-movement and then interact with the desired application.
Therefore, our proposed platform can serve various services.
The paper is organized as follows. Section 2 introduces the
related works with eye-movement detection. Some classical eyemovement
measurement techniques for recording the electrical
activity of eye-movement will be described in details in this
Section. The proposed EOG-based eye-movement HCI platform is
given in Section 3. Some propose prototype applications for
eye-movement are shown in Section 4. The diverse guidance tests
and experimental results are given in Section 5. Finally, Section 6
draws the conclusion and future work.
