Anna is one of a large group of Spanish students visiting Athens as part of a School trip. They are learning about classical Greece and before their visit they have already been enjoying an interactive, real time virtual course on the subject of ancient Greek architecture. Whilst visiting the Akropolis, she accesses the eLearning application again and indicates the topics she is interested in. The application running on an IRMOS enabled platform considers her device capabilities and the kind of services she needs and, constructs a virtual reality learning environment that she can move around in with her fellow students. This allows her to interact with her colleagues and other virtual visitors as she moves around the venue. She is be able to interact with the learning material by accessing real time multimedia content, using video streaming and seeing a visualisation of how the Akropolis used to look.

The virtual environment allows access to information from other locations, for example she can access the National Museum of Athens to gain further information on artefacts found at the Akropolis and to interact with other members of her class who are visiting the museum at the same time. After the visit, all the students gather together in a nearby hotel where they are staying and request to video conference with an expert on classic Greek architecture in order to have a deeper explanation on the history of the Parthenon and to discuss what they have collectively learnt during the day. IRMOS allows them to video conference with a curator on duty at the site who also delivers some multimedia material for supporting his explanation.

Technical analysis:

• A large number of people interacting with one another through a virtual environment with a need for synchronisation of experience.
• Real-time delivery of multi-media material to users with adaptation of the service rates based on the users’ ability to consume the delivered data rate and on the number of simultaneous users of the system
• Automated selection of the best source of material for delivery to the user and automated construction of the service over the network
