“…The relative voltage to the actual eye positions is plotted in Figure 4E, where it can be seen that the curve represents a perfect linear relationship. Consistent with previous EOG studies, [54][55][56] Figure 5E reveals that the relationship between the eye angle and the amplitude of the measured EOG voltage signal was linear, up to 40 , which makes it quite useful for human-computer interface applications. 56,57 tAgTrode Outperformance Compared with Other Electrodes The most distinguishing factor in thus-far developed wearable devices for monitoring eye parameters is the effect of ambient electrical noise and motion artifacts, i.e., spurious signal fluctuations caused from even the smallest of head or body movements, on the desired EOG signal.…”

We present a first-of-its-kind fabric hydrogel electrode that is reusable and washable, does not cause skin irritation, and can be continuously operated for upward of 8 h without losing signal integrity. Second, we report an ion-based fabric pressure sensor that measures pulse waveforms when placed on the face. We decorate a lightweight eye mask with these novel fabric electrodes to create a portable detection platform named ''Chesma,'' which can wirelessly track eye motion and pulse in natural environments over long periods of time.

“…Most recently, the prototype called PANTOJO focused only on the hardware stage and presented a compact gaze tracker in which the electrodes are secured in an elastic head band [ 20 ]. Another interesting piece of research is the comparison between the techniques proposed by R. Barea and A. Bullings’ works [ 21 ].…”

The development of a novel computer writing system based on eye movements is introduced herein. A system of these characteristics requires the consideration of three subsystems: (1) A hardware device for the acquisition and transmission of the signals generated by eye movement to the computer; (2) A software application that allows, among other functions, data processing in order to minimize noise and classify signals; and (3) A graphical interface that allows the user to write text easily on the computer screen using eye movements only. This work analyzes these three subsystems and proposes innovative and low cost solutions for each one of them. This computer writing system was tested with 20 users and its efficiency was compared to a traditional virtual keyboard. The results have shown an important reduction in the time spent on writing, which can be very useful, especially for people with severe motor disorders.

“…EOG signals vary from subject to subject and with different electrode contacts and according to the surrounding light, as well as with perspiration on the patient's temples [17]. Thus, a software program has been developed to calibrate the eye position.…”

This paper describes a new low-cost real-time communication assistive system for disabled people, especially those with only eye-motor coordination. The retinal resting potential causes an electric field around the eyeball, centred on the optical axis, which can be measured by placing electrodes near to the eye. An acquisition system was implemented for measuring this potential in order to detect the movement of the eyes and to provide a relative gaze position, making it possible to codify ocular actions as commands. A human-computer interface (HCI) to control the mouse and a virtual screen keyboard, that offers simple setup combined with high performance, have also been developed. This device has multiple applications, especially in assistive research, where control is governed by means of the ocular position (eye displacement in its orbit). The theory behind the device and the hardware and software design of the system are presented.
