Assistive Application for Children with Dyslexia and Dysgraphia (AACDD)

Non-Confidential description of the invention

Invention is a training module for the school going children between classes 1 to 5 diagnosed with dyslexia and dysgraphia. It involves visual and auditory feedbacks putting haptic sensation and motor movement in loop to facilitate acquisition and reproduction of Hindi letters. AACDD is a touchscreen-based interface designed to assist children with dyslexia and dysgraphia in self-training as well as under supervision, predominantly for Hindi. It enables them to read on screen assisted through auditory feedback and trace fonts to learn formation of words through haptic feedback. Integrating auditory inputs with visual manipulation should help the child retrain their brain networks in identifying the geometric patterns called ‘words’.
