The project DocToon© is an animation and rendering 3D system intended for paediatric wards to humanise the stay of hospitalised children and to help them to cope with the psychosocial problems they face. The principle of the technology is to animate, in real time, a little character, who can talk with the children in hospital, appearing to them via the television set in their room. An animator, in a room situated a little way from the children rooms, brings the character to life and speaks on his behalf, while seeing, via a two-way video the child with whom he is engaged in talking.
