Vivian Genaro Motti is the next speaker at EuroITV 2009, and she continues the semantic theme. She begins, though, by highlighting the shift towards ubiquitous computing, which is allows for a capture-and-access process - capturing everything in the environment of the user, and accessing this in the context of later use (used e.g. to document meetings). Such material may then also be further annotated, of course, augmenting captured video with comments, information, and other details.
This, then, enables user collaboration, even a kind of social TV based on iDTV technologies. This utilises a watch-and-comment (WAC) approach which captures individual user comments and generates annotated interactive video files. A technology developed by the present project, the WaCTool, uses digital ink, text, and voice for the creation of such metadata, provides text-based chat functionality, and generates annotated video files. Such collaboration enables group communication and creates enriched content, which may be useful in a variety of contexts.
There are two main approaches to this - sharing annotated video files created by each user, or sharing the ongoing annotation sessions themselves, which enables users to see what their peers are annotating as they're doing it. This latter model was explored by the project, which evaluated its Collaborative WaCTool (CWaCTool) prototype.
