Abstract: When tourists are wandering around in a town or city they do not know, it is normal to use a guide to make up their mind on what is more interesting in the surrounding. If the guide is an interactive one on a mobile device, they can also consult multimedia material and listen to audio descriptions. But what if the user is a children that is much more prone to get distracted? In this paper, we propose the presentation of touristic and cultural information to children through an augmented-reality approach. In order to keep focused the attention of the young users we make use of a virtual tourist guide, appearing as a comic book superhero. To get a realistic representation of the avatar we exploit a technique for fast simulating talking heads, which is portable on mobile devices. The technique is based on preloading a set of meshes representing different phonemes and switching among them in order to simulate animation, without the need of computing the update for an entire face model. In addition, we report on a first Android prototype, which shows the effectiveness of the approach for increasing children’s learning.
