HyPE-aiM – Framework for dynamic, interactive hypermedia
Common browsers like Firefox, Internet Explorer, etc. handle HTML. This means that the hypermedia metaphor in these applications is reduced to a hypertext realization. Interaction using links in other media, for example images, is difficult to realize; interaction using links in dynamic media such as video or audio is not supported at all. To use links in videos specialized hypervideo applications have to be used. But those kinds of applications again reduce the hypermedia metaphor to the single medium “video” (see: Adivi, Aterpix). There are currently no applications which support static (hyper-)media as text and images in combination with dynamic (hyper-)media as video and audio.
The HyPE-aiM project has the goal to develop a flexible framework for the presentation of interactive hypermedia applications for static and dynamic hypermedia in combination. This means a change as well in design and production as well as in interaction:
- As the medium itself has a time-related behaviour, the behaviour of the links (hotspots) also changes. Hotspots have to move with the related visible object, appear and disappear with them.
- Highlighting links in images and in videos means an influence in the picture language.
- A link is not available all the time but may appear and disappear without any user interaction.
To support these challenges the HyPE-AIM framework was designed in three modular parts:
- a browser which handles the rendering and the interaction of the combined static and dynamic hypermedia content;
- an authoring tool which supports producers with specialised functionalities to create and structure the content. This is described by an XML-based language which includes the definition of the layout as well as the definition of links and the behaviour of the media;
- an API which opens the framework for the use in other presentation environments, so the HyPE-aiM browser can be used within other applications as part of the user interface.
Currently, the concept of the HyPE-aiM framework is finalized and the browser has been implemented. For the first demonstration an interactive hypermedia presentation of the TZI eXpo, an interactive real-world exhibition of research prototypes at the University Bremen, was developed. Instead of using text links, the navigation through the exhibition is realised by interactive (hyper-)videos. The (virtual) visitor clicks on exhibits and doors to walk through the exhibition and to look for detailed information. The combination of static and dynamic hypermedia helps the experience not to lose the interactive characteristic of the real-world exhibition in the virtual presentation. This helps to explain the exhibits in a more intuitive way. While usually reading texts of the exhibits’ functions and backgrounds, the HyPE-aiM demonstrator presents the TZI eXpo exhibition nearly as interactive as it is in reality.
The HyPE-aiM presentation will be launched with the re-opening of the TZI eXpo.
