In ever increasing frequency, designers are required to collaborate across large geographical boundaries. This collaboration presents the participants with new challenges. In this paper we describe how we have addressed two of these challenges using Internet technology. The first challenge is "How can designers discuss complex design artifacts at a distance?". Designers' discussions have a complex structure. For example, a designer can refute, justify, or revise a design proposal. These discussions are traditionally supported by sketches and formal diagrams. In this paper we show how our solution allows designers to have the same rich forms of interactions, over the Internet, with the minimum changes to their style of work. The second challenge we have addressed is "How can previous design solutions be made reusable between collaborators separated by a large distance?". Reusing old solutions is a common design practice. Sharing solutions across institutions presents an interpretation problem, as institutions may describe their solutions using different terminology. Organising a shared library also raises challenges. There is a trade-off between reducing the time to find a previous solution and reducing the duplication of design solutions across institutions.

Future Internet is...


Future Internet
With over a billion users, today's Internet is arguably the most successful human artifact ever created. The Internet's physical infrastructure, software, and content now play an integral part of the lives of everyone on the planet, whether they interact with it directly or not. Now nearing its fifth decade, the Internet has shown remarkable resilience and flexibility in the face of ever increasing numbers of users, data volume, and changing usage patterns, but faces growing challenges in meetings the needs of our knowledge society. Globally, many major initiatives are underway to address the need for more scientific research, physical infrastructure investment, better education, and better utilisation of the Internet. Within Japan, USA and Europe major new initiatives have begun in the area.

To succeed the Future Internet will need to address a number of cross-cutting challenges including:

  • Scalability in the face of peer-to-peer traffic, decentralisation, and increased openness

  • Trust when government, medical, financial, personal data are increasingly trusted to the cloud, and middleware will increasingly use dynamic service selection

  • Interoperability of semantic data and metadata, and of services which will be dynamically orchestrated

  • Pervasive usability for users of mobile devices, different languages, cultures and physical abilities

  • Mobility for users who expect a seamless experience across spaces, devices, and velocities
