Interactive number learning system for mentally challenged children

Depending on the way the mentally challenged children learn things, they are categorized into groups such as visual learners, auditory learners, reading /writing preference learners, kinesthetic learners. This paper integrates all the learning abilities of mentally challenged children and proposes an Interactive Number Learning System. It helps mentally challenged children to learn the basic numbers between 0-9. Here, sensors are used for this purpose to activate the required message pin so that, the speaker gives the voice of the particular number. It consists of both passive and active levels to entertain as well as to encourage the child to think and play.
