Natural eye gaze computer interaction for medical oculography diagnosis: Current status and future prospects

With recent technological developments, modern computing systems are becoming more and more powerful. Common computers are capable of calculating more than 50,000 million instructions per second. Currently the biggest obstacle in computer usage is slow communication between the human and the computer. With innovation and development of novel (natural based) sensors capable of capturing positions and natural motion of human body a new, natural, way of interacting with computer is enabled. This paper gives an overview of eye tracking technology, and presents its application in nature based human-computer interaction (HCI) systems by extending standard controllers, such as the keyboard and the mouse. Novel approaches enable HCI closer to the communication patterns of human beings. In addition, the usage of those concepts in applications for eye diseases and disorders diagnostics and rehabilitation is discussed.
