Environment design for the creation of children's games incorporating virtual avatars. Using Unity 3D as development environment. The purpose of the project is to encourage children to be protagonists not only of the process for the creation of the framework, but also to feel identified with something that they themselves created. The project is called VG 4 KIDS (Video Game For Kids). The concept of the framework was obtained by conducting interviews with children throughout the process, in order to obtain a result that they liked. Currently the application is in the Android PlayStore (For mobile devices and Tablets).
