Overview

Web applications have overcome traditional desktop applications especially in collaborative settings. However, the bulk of Web applications still follow the "single user on a single device" computing model. Therefore, we created the DireWolf framework for rich Web applications with Distributed User Interfaces (DUIs) over a federation of heterogeneous commodity devices supporting modern Web browsers such as laptops, smart phones and tablet computers. The DUIs are based on widget technology coupled with cross-platform inter-widget communication and seamless session mobility. In particular, we built DireWolf on top of the ROLE SDK and its XMPP-based Inter-widget communication. Inter-widget communication connect the widgets and enable real-time collaborative applications as well as runtime migration in our framework. For a single user, DireWolf provides more flexible control over different parts of an application by enabling the simultaneous use of smart phones, tablets and computers. As reference use case of the DireWolf framework we realized a collaborative semantic video annotation application in the domain of cultural heritage documentation.

Demonstrator:
  1. Open the following link (http://vostell.informatik.rwth-aachen.de:8073/) in a  modern browser (Chrome, Firefox)
  2. Sign in with a Google account
  3. Create device(s) (at least on device associated with the current computer)
  4. Enter the space 'ICWE2013' (alternativelly, open the link http://vostell.informatik.rwth-aachen.de:8073/spaces/ICWE2013)
  5. Do steps 1-4 on another device(s) (e.g. tablet, smartphone)
  6. Wait till the other device shows online in the left sidebar, then you can migrate widget by drag and drop in the sidebar
