Although some interesting architectures are emerging to define and formalize the notion of Adaptive Hypermedia, the research in this field is primarily focused on presentations based on static contents, mainly text and images. We propose an initial step toward the adaptative composition of video documentaries, that is video presentations based on still 2D images. Video clips are built by applying cinematic techniques - camera movements and transition effects - to images. The novelty of our approach stems from the application of adaptive hypermedia techniques to the dynamic composition of video documentaries exploiting the basic notions of cinematography, paying particular attention to the choice and the duration of transitions between shots. In this work we introduce XASCRIPT, a flexible mark-up formalism that allows a hypotetical author to define a set of possible video documentaries, from which user-tailored documentaries can be dynamically assembled. The author, via a graphical interface (under development), can describe templates that represent a set of 'potential' video documentaries, with instructions for the selection and the editing of the elements of the video clips. The templates include 'adaptation rules' as multiple-choice points, along which the presentation is tailored to a specific user. The application supports both content adaptation and dynamic selection of transition effects between video shots

Abstract
Although some interesting architectures are emerging to define and formalize the notion of Adaptive Hypermedia, the research in this field is primarily focused on presentations based on static contents, mainly text and images. We propose an initial step toward the adaptative composition of video documentaries, that is video presentations based on still 2D images. Video clips are built by applying cinematic techniques - camera movements and transition effects - to images. The novelty of our approach stems from the application of adaptive hypermedia techniques to the dynamic composition of video documentaries exploiting the basic notions of cinematography, paying particular attention to the choice and the duration of transitions between shots. In this work we introduce XASCRIPT, a flexible mark-up formalism that allows a hypotetical author to define a set of possible video documentaries, from which user-tailored documentaries can be dynamically assembled. The author, via a graphical interface (under development), can describe templates that represent a set of 'potential' video documentaries, with instructions for the selection and the editing of the elements of the video clips. The templates include 'adaptation rules' as multiple-choice points, along which the presentation is tailored to a specific user. The application supports both content adaptation and dynamic selection of transition effects between video shotsI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
