ATLAS: Architecture for T-Learning Applications and Services
Principles of ATLAS
• Promote reusability:– Unifying the platform: MHP
• Peculiarities: Latencies, synchronising with streaming media, low computational demands, etc.
– Unifying the courses: SCORM
• Media-driven strategies– Mainly, audiovisual material– Contextual binding:
• Identifiers linked to pieces of information
• Defined differently for the different types of content– Timestamps in fragments of audio and video– Regions in images– Anchors in a text– Options in menus, etc.
