Before we go deeper into R.A.D.A.R. Method, lets introduce some helpful definitions.
Fixation is the maintaining of the visual gaze on a single location. On average, fixations last for around 200 ms during the reading of linguistic text, and 350 ms during the viewing of a scene.
Saccades are quick, simultaneous movements of both eyes in the same direction.
Reading path is the resulting series of fixations and saccades.
Visual acuity describes the acuteness or “sharpness” of vision; that is the ability to perceive small details.
Regression is a backward movement of the eye when reading a line of text- good readers do it less than weaker readers, who go back to check things more frequently.
The reading path of a normal reader (left) and a dyslexic reader (right). Blue circles are the fixations and the orange lines are the saccades. The bigger the circle, the longer the fixation duration.
