According to the invention, a method for entering text into a computing device using gaze input from a user is disclosed. The method may include causing a display device to display a visual representation of a plurality of letters. The method may also include receiving gaze information identifying a movement of the user's gaze on the visual representation. The method may further include recording an observation sequence of one or more observation events that occur during the movement of the user's gaze on the visual representation. The method may additionally include providing the observation sequence to a decoder module. The decoder module may determine at least one word from the observation sequence representing an estimate of an intended text of the user.
