Background
The index of eye movement data during reading is gradually introduced into the study of reading assistance at home and abroad. The study finds that when children with reading disorder read, the fixation time is longer, the fixation and fixation times are more, the eye movement track is chaotic, the attention is difficult to concentrate on the characters, and the reading position can not be positioned, so that the real-time eye browsing stay position and the capturing of the eye movement track can provide assistance for reading training.
"color overlay" generally refers to placing Colored transparent plastic reading paper over the reading text, and using the visual effect to reduce visual fatigue caused by reading a person with a reading disorder during the light entering the human eye.
However, different people show obvious individual differences in color preference and adaptability to the transparent plastic sheet, and if the correct color is not used, the obvious effect cannot be achieved. Even subtle differences in color saturation and brightness may sometimes bring about different results.
The application mode of the existing color lamination method mainly comprises an entity and a virtual entity, wherein the entity generally refers to a method for manually placing a color film on a reading text to relieve related symptoms (such as the use of the transparent color plastic sheet); virtual then refers to a method of processing text in an electronic screen based on this principle (e.g., using word toolbars to fill text with ground color).
The entity has the advantages of portability and wide application scene, but the user needs to hold the color film on the text, and meanwhile, the color of the color film is less, the parameters cannot be changed, and the color most suitable for the user is difficult to find.
Virtual color overlay applications have a high degree of freedom in terms of adjustment of color parameters, but students are high in a population that needs a lot of read text, and the amount of read physical text in daily life of such population is much higher than that of electronic text, which is difficult for virtual systems to meet.
Furthermore, studying the eye movement track of a dysread person finds that after reading a line of text, it is difficult for the dysread person to control his or her gaze to fall exactly at the beginning of the next line of text like an average person, if guided by appropriate markers, will help these people read.
