Information technology is transforming di erent areas, such as reha bilitation, in such a way that serious games are finding a use as an alternative in hearing therapies for children with cochlear implants, creating a motivating expe rience in children. As a result, the design of products for children depends on the skills they have to interact, because if they have a better experience they may have a better learning experience. Most existing methods of assessment are aimed at adults, although some have been adapted for children with special needs, including children with cochlear implants.
