Why use Dyslexia Reader by MDA? + Use books you already have Use any age-appropriate books you have from your child’s school syllabus. You do not need any special PDFs or web resources and can add a page by simply capturing an image with text in it. Several pages can also be added at the same time. + Enables finger-reading The pencil icon on the reading page can be dragged with the help of a finger. With this, the child can track the words they are reading.This also lowers convergence difficulties while aiding hand-eye coordination. A red underline is used to mark the words already read to avoid rereading the same. An indicator shows the next word to be read. The pointer can be easily re-positioned by double-tapping the new word. + Promotes stress-free reading Multiple reader view gives the child the option to read only one part of the text at a time. There are three different reader views on the app. - Page view shows the entire page - Sentence view shows only one sentence at a time - Word view shows just one word + Promotes distraction-free reading Multiple features create a distraction-free reading experience for the child - Use Plain-text mode to remove background images to show only bare text - The Focus button highlights a single line on the page which contains the current word to read. This maintains the child's visual focus on the highlighted word, and helps avoid visual over stimulation. This feature works in both text and photo mode. + Hints to encourage reading When the child finds it difficult to read a particular word, they can tap the Hint button. This ensures that the child is not discouraged by a new or seemingly difficult word. Additionally, the use of Hints will also stimulate phonemic and conceptual understanding. A variety of Hints available on the app are - - Rhyming words and images - Word family hints - Hints for starting, middle and end blends + Build comprehension skills The Build feature helps in parsing the sentences in the text and focusing on the smaller syntactic units. When building, the app shows the text, one sentence at a time. Tapping the “Build more” button gradually builds up the sentence. This enables children to comprehend the text more effectively. + Key features - No active internet connection required after download - Import a PDF document quickly to your library - Share your already-reviewed pages with other MDA Dyslexia Reader users - Easily customize settings - Seamless keyboard integration for reviewing - User-friendly buttons for simple understanding - Prompt support on mail and chat - Real-life text analysis - High-quality text-to-speech feature - Screen-masking to aid focusing - Synchronized highlighting of text - Hints available as rhyming words and images - Colored overlays to assist readers with Irlen Syndrome - Breaking down words into syllables - Word families based on syllables - Configurable speed and progress - Independent and assisted user flows - Download exciting books from within the app Dyslexia Reader by MDA is developed by Madras Dyslexia Association.
