Cognitive science is an effective approach for bringing mentally retarded person in to live normal way of life. Overcoming cognitive disorders involves initiating the growth of natural thinking. A large population in this world is suffering from cognitive disorders either less or more. Cognitive disorders can be of due to developmental issue or acquired from illness/accidental. Cognitive development can be achieved by natural therapy by stimulation of specific neuronal network which are involved in cognition. Brain based skills that involved in this make a complex task into simpler task. These skills show how we learn, how we think, how we remember and most importantly how we respond to a specific situation. For instance, perception is the recognition and interpretation of opinion or in what way you are taking problem and solving in which way because a single problem solved by different persons in different way of thinking. In such a situation it is very important to develop basic cognitive abilities in infants in its early developmental stage by providing necessary therapy in childhood. To bring this reality in society here an attempt will be made to design a virtual therapy device that will give the necessary exercises to the infants for growth of proper neural network i.e. brain development to overcome mental retardation and cognitive disorder.
