Tech Report kmi-96-03 Abstract


Multidisciplinary Modelling for User-Centred System Design: An Air-Traffic Control Case Study
Techreport ID: kmi-96-03
Date: 1996
Author(s): Simon Buckingham Shum, Ann Blandford, David Duke, Jason Good, Jon May, Fabio Paterno' and Richard Young

This paper reports work investigating how user and system modelling techniques can be integrated to support the design of advanced interactive systems, and how such modelling can be effectively communicated to design practitioners in order to evaluate their potential. We describe a large scale modelling exercise concerning a flight sequencing tool for air-traffic controllers. We outline the kinds of system and user analysis possible with the different modelling techniques, and the approach used to integrate and communicate the modelling analyses to the system's designers. We then discuss the value of these techniques against several key criteria. The designers evaluated the modelling positively in many respects, including a commitment to explore further how user modelling can be integrated with their formal methods. We conclude that the scenario of HCI modellers working in collaboration with designers is feasible, and has analytic power. 1.

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
