eyewriting

Eyewriting is a method of assistive technology that allows individuals with severe physical disabilities, such as those with locked-in syndrome, to communicate and control a computer using only their eye movements. This technology typically involves a specialized camera system that tracks the user's gaze with high precision. By directing their eyes towards specific on-screen targets, users can select letters, words, commands, or activate various computer functions.

The core components of an eyewriting system include an eye-tracking device, often a camera mounted near the computer screen, and sophisticated software. The software calibrates to the user's unique eye characteristics, learning how their gaze corresponds to different points on the screen. Users can then select items by dwelling their gaze on them for a predetermined amount of time. This allows for typing text, browsing the internet, operating applications, and interacting with the digital world without the need for physical input devices like keyboards or mice. Eyewriting significantly enhances the independence and quality of life for individuals who would otherwise have limited means of communication.
