An Intelligent Human-Machine Interface Based on Eye Tracking for Written Communication of Patients with Locked-in Syndrome

A deliberate loss of mobility throughout the entire body, with the exception of the muscles that control eye movements, is referred to as "locked-in syndrome" (LIS). Patients are conscious and awake despite this. They can communicate by blinking or moving their eyes, and their mental faculties are frequently unharmed. LIS sufferers are less productive since their everyday routines are substantially affected and they need continual assistance. Currently, many people use assistive technology to make up for their limitations. In order to capture eye movements, gaze courses, a client’s location on the screen at any given moment, and the grouping of their development, eye tracking is now being logically researched in Human PC Interaction. This is because eye tracking technology has advanced from an idea to the physical world. It may be argued that eye development is a crucial constant input technique for human-PC communication, especially for those who are genuinely impaired. The suggested framework aims to provide a straightforward and useful interactive mode using only the client’s eye. The proposed framework’s use stream is designed to flawlessly correspond to human tendencies. A magnifier module is also suggested to enable the precise activity. The Innovation Acknowledgment Model (Cap) measures are used to evaluate the framework’s apparent suitability. The proposed framework’s extreme persuasiveness in terms of usability and interface design is demonstrated.
