%A Frederic Kaplan %A Verena Hafner %T The Challenges of Joint Attention %X This paper discusses the concept of joint attention and the different skills underlying its development. We argue that joint attention is much more than gaze following or simultaneous looking because it implies a shared intentional relation to the world. The current state-of-the-art in robotic and computational models of the different prerequisites of joint attention is discussed in relation with a developmental timeline drawn from results in child studies. %K joint attention, intersubjectivity, developmental progression, shared intention %P 67-74 %E Luc Berthouze %E Hideki Kozima %E Christopher G.
