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.

“…But by using EOG along with EEG there is unnecessary increase in complications and time due to EEG judgment. [7][8].Recently researchers proposed an approach of interface that allows people to interact with computers using their eye movements is presented as the eye movement is the easiest way of communication [9], Study and capturing of the Natural eye movement detection for assisting application for paralyzed patients with motor disorders.…”

“…For instance researchers used EOG to control a robot arm moment [17], guide a wheelchair [15], or a key-board [14]. Such a system which provides both ease and communication for disabled people, particularly when there is some physical restriction that avoids them from using other Human Computer Interface.Some researchers work came with the problematic condition due to involuntary as well as voluntary blink signals, to overcome this problematic condition author proposed the new method by varying the position of the electrodes varying in position there is change in output voltage, difference between involuntary as well as voluntary blink signals to remove effect of such false trigger [17] [9].…”

Abstract-There is sufficient evidence about feasible use of electrical bio-signals in field of Substitute Communication. Additionally, they are particularly suitable in the case of people with physical disorder, for example bedridden patients. Developing solutions for them involves different ways of using sensor that decides the user's restrictions & needs, which in turn converts the user's intentions into commands. The system should be assessed with an appropriate solution. This paper submits alternative communication techniques used for communication using electrooculography technique.

“…A real time EOG signal Deterministic Finite Automata (DFA) classifier for microcontrollers is proposed in (Trikha et al, 2007). A new low-cost realtime communication assistive system for disabled people is proposed in (Lopez et al, 2014). A wireless EOGbased HCI device is used for detection of eye movement in four directions in (Supraja, 2014).…”

The Electro-Oculogram (EOG) signal can be used for detecting the normality of the eye retina. A number of advantages including the flexibility of the recoding process for EOG signals have encouraged insight into EOG based research. This study proposes a new cloud based retinal detachment screening technique based on data mining techniques to diagnose the type of eye retina. The used recognition methods include: back propagation neural network, Kohonen neural network and support vector machine. The obtained results are classified as normal or abnormal eye retina. Given a training set of such patterns, the proposed system is trained how to differentiate a new case in the domain. The diagnosis performance of the proposed systems is evaluated using more than one performance measure such as statistical accuracy, specificity and sensitivity. The diagnostic accuracy of the proposed neural network has achieved a remarkable performance with 100% accuracy on training and test subsets. The main advantage of the proposed system is the high quality of the diagnosis process that help health team to take the suitable decision regarding the patient case. The proposed system may help reducing the cost of screening patients especially in rural areas where experts are not available through sending their data to a central site where the automatic system will help an expert to diagnose the suspected cases.
