Concurrent programming by children
This event took place on Wednesday 05 October 2005 at 14:00

Dr. Ken Kahn London Knowledge Lab, United Kingdom

Many have extolled the benefits of learning by building and exploring computational models. But typically computer programming requires a mastery of complex computational abstractions. The research we'll be presenting describes a way to replace these abstractions with playful, animated, game-like, virtual objects without sacrificing expressive power. We'll present via live demos three systems that have explored this idea. ToonTalk (www.toontalk.com) is a general-purpose concurrent programming language that presents program building blocks in terms of familiar objects. A ToonTalk programmer trains robots to manipulate boxes containing numbers, text, pictures, sounds, birds, trucks, robots, and other boxes. Birds are the means that program fragments coordinate and communicate. Trucks are used to spawn new sub-computations. The Playground Project (www.ioe.ac.uk/playground) provided tools to children 6 to 8 years old enabling them to make their own computer games. Playground built upon ToonTalk. It provided the children with transparent components and behaviours that could be assembled or broken down into for modification and reassembly. The WebLabs Project (www.weblabs.eu.com) is providing children 10 to 14 years old with components and learning materials to explore science by building computational models and mathematics by building ToonTalk programs. Children publish their reports which typically include runnable models or programs on the project web site. Other children across Europe read and post public comments on these reports.

ToonTalk was designed and built by Ken Kahn who, after earning a doctorate in computer science from MIT, has spent 30 years as a researcher in programming languages, computer animation, and programming systems for children. He has been a faculty member at MIT, University of Stockholm, and Uppsala University. For over eight years he was a researcher at Xerox PARC. In 1992, Ken founded Animated Programs whose mission is to make computer programming child's play. He has participated in two large-scale European research projects that have built upon ToonTalk.

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
