How to… is a video modelling program for children that shows how to perform some specific everyday activities. Video modelling is a way of self-learning by imitation, developed through the presentation of films that illustrate appropriate ways of behaving or actions to be performed for specific purposes. The activities are divided into two categories: personal hygiene (teeth, face, hands) and dressing/undressing (t-shirt, shirt, trousers, jacket with zipper). Each activity is divided into 4 to 10 videos; An attractive and intuitive digital interface makes it possible to watch the next video, the previous one or to select a specific scene. Available activities can also be selected through tangible interfaces such as PECS or specific objects (e.g. a toothbrush).
