First Claim
1. An eye typing system comprisingan eye tracking device for monitoring the movements of an eye, including gaze, fixation and saccade;
- a display apparatus including an on-screen keyboard user interface configured as a three-layer arrangement comprising an outer ring of alphabet characters, an inner ring of frequently-used words and a central region for displaying typed text; and
a computer processor responsive to the eye tracking device for analyzing eye gaze and fixation data and determining which key of the on-screen keyboard user interface an individual has selected by eye movement, the letter or word associated with the selected key being displayed in the central region.

Abstract
A specially-configured interactive user interface for use in eye typing takes the form of a three-layer arrangement that allows for controlling computer input with eye gazes. The three-layer arrangement includes an outer, rectangular ring of letters, displayed clockwise in alphabetical order (forming the first layer). A group of “frequently-used words” associated with the letters being typed forms an inner ring (and is defined as the second layer). This second layer of words is constantly updated as the user continues to enter text. The third layer is a central “open” portion of the interface and forms the typing space—the “text box” that will be filled as the user continues to type. A separate row of control/function keys (including mode-switching for upper case vs. lower case, numbers and punctuation) is positioned adjacent to the three-layer on-screen keyboard display.
