- We describe a Web 3.0 interaction system where the mobile user scenario is combined with a touchscreenbased collaborative terminal. Multiple users should be able to easily organize their information/knowledge space (which is ontology-based) and share information with others. We implemented a MP3 and video player interface for the physical iPod Touch (or iPhone) and the corresponding virtual touchscreen workbench. The Web 3.0 access allows us to organize and retrieve multimedia material from online repositories such as YouTube and LastFM.
