This study investigates the concept of adaptivity in relation to the evolution of software and hence software embedded products. Whilst laying out the benefits of adaptivity in products, it discusses the potential future threats engendered by the actual change observed in the functionality principles of adaptive products. The discussion is based upon cybernetic theory which defines control technology in the 20th century anew. Accordingly, literature survey on cybernetic theory, evolution of software from conventional to adaptive structure is presented. The changes in the functionality principles of adaptive systems and the similarities that these changes show with living autonomous systems is also investigated. The roles of product and user are redefined in relation to changing control mechanisms. Then, the new direction that the conventional product-user relationship has taken with adaptive products is examined. Finally, the potential future threats this new direction might bring is discussed with the help of two control conflict situations.

Early musical experiences are very important for social, cognitive and physical development of children, as well as their future musical competences. Preschools present this environment with various musical materials. However, suitability of these materials in terms of developmental needs of children and educational goals is questionable. The purpose of this study is to transfer knowledge from relevant literature to design considerations of musical toys for preschool children. Literature review was conducted to determine various aspects to be considered while designing musical toys by compiling knowledge from developmental psychology and pedagogy literature / governments
