According to English Oxford Living Dictionaries the word "dyslexia" is defined as "a general term for disorders that involve difficulty in learning to read or interpret words, letters, and other symbols, but that do not affect general intelligence" [1]. Dyslexia results from individual differences in the parts of the brain tht enable reading. It tends to run in families. Dyslexia appears to be linked to certain genes that affect how the brain processes reading and language. A study was done to look at the impact of different text formatting techniques on readability, Daniela Traficante, Laura Giordano, and Giovanna Mazzotta (2020) [2] conducted a study with 128 participants (64 with dyslexia and 64 without dyslexia). Reading speed and accuracy for those with dyslexia were found to be greatly improved with more space between letters and words. The study highlights how crucial it is to employ various text formatting strategies to increase text readability for those who have dyslexia. Another study by Sierra Laddusaw and Jeremy Brett (2019) [3] found that incorporating the Open Dyslexic font in exhibit materials at Cushing Library improved access for dyslexic visitors. The results of adding Open Dyslexic font to the exhibit were positive. The study by Bonifacci et al. (2021) [4] examined the effects of text-to-speech technology on rates of mind wandering in students with dyslexia (20) and typical development (50). The results showed that both groups had better comprehension and reduced rates of mind wandering in the text-to-speech condition. Sweep Sweep Spell technique by Ronald Dell Davis [5] is a native approach in which students are usually instructed to hide the words they are reading with a finger and slide the finger by one letter then it continues from reading out each letter loud to the whole word. WebHelpDyslexia [6], intended to assist in making web material more readable for people with dyslexia. The application has options for modifying the font size and type, stripping away text decorations, altering the foreground and background colors, and finding synonyms for words. Preliminary evaluations with dyslexic users showed that the features to help concentrate when reading and considered very useful. Web pages to make reading easier, such as font type, font size, letter spacing and word spacing (e.g., Open Dyslexic for chrome [7], Dyslexia Reader Chrome [8], Dyslexia Friendly [9], and Helper bird [10]), Helper Bird stands unique and provide additional features to contrast between text and background colors and line.To gain their interest VAKT (Visual, auditory, Kinesthetic and Tactile) has been introduced which uses a Multisensory technique [11], this technique has shown increased engagement and achieved a promising result with students in learning. Another study by Siti Khatijah Nur Abdul Rahim and Nur Hasni Nasrudin (2018) [12], stated that if the multi-sensory method was adopted in learning strategy it could help dyslexia. The learning strategy refers to teaching dyslexia persons more than one of the five sense like tactile method and visual memories. Augur and Brigger developed Hickey Multisensory Language Course program [13]. Stratigoula Politi-Georgousi [14], numerous mobile apps have been designed and developed to assist them with specific learning skills such as reading, writing, spelling etc. A preliminary study was undertaken by Jorge Buele, Victoria M. López, L. Franklin Salazar, Jordan-H. Edisson, Cristina Reinoso, Sandra Carrillo, Angel Soria, Ral Andrango, and Pilar Urrutia-Urrutia (2020) on an interactive system to improve the skills of children with dyslexia[15]. Another study was conducted by Aleksandra Sholdova (2020) [16] on how educational games can benefit dyslexic children. They found that multi-sensory learning style using interactive games can potentially enhance the learning process, making it easier to acquire and comprehend the material. A study by James Ohene-Djan and Rahima Begum introduces The Dyslexia Activity System (DAS), an online learning tool that makes use of multisensory learning [17] to give dyslexic students a fun learning environment in which to pinpoint their reading, writing. Study [18] by Maria Rauschenberger, Luz Rello, Ricardo Baeza-Yates with students of age from 7 to 12 introduces a web-based prototype to screen pre-readers. Dyslexics need to understand and sustain today's internet as well, but it is not convenient for them to utilize it like other people do. So we developed a compact web app called "Dyslexi Duo".which comprise of 3 major features "Super Pad", "Hydra Hunt", "Alpha 360". The approach of these features is thoroughly explained in Section 1.The functions as well as the outcomes of our application "Dyslexi Duo" are covered in Section 2.The results that are derived are included and explained in Section 3. The significance of the application is concluded in Section 4. References are provided in the final section.
