Every year the Royal Society opens its doors to the public for the Summer Science Exhibition. For this year's exhibition Pete Shadbolt, a Physics PhD student, worked alongside the maths department at the University of Bristol to build a DI multitouch surface, illustrating recent work on quantum graphs and isospectrality.

In this talk he will discuss the practicalities of cheaply building a multitouch table, the science, maths and technology behind the system, and potential future applications.

For more information on the exhibit click here, read write-ups of the exhibit in the New Scientist, and Physorg.com, or listen to podcasts about the Summer Science Exhibition from The Guardian and The Financial Times.

Join us for this unique opportunity to interact with the surface for yourself.

This Lunchtime Talk is part of Open Studio Friday, which takes place at the Studio every week

Do you want to find out what is going on at the Pervasive Media Studio? Are you interested in meeting our residents, talking about a specific project or curious about pervasive media? Why not pack a sandwich and join us for one of our Lunchtime Talks and Open Studio Friday.

Lunchtime Talks are informal presentations by Studio residents and associates. They normally take place at 1pm on Friday, are free and open to everybody who’s interested in what we do.

After the Talk, we also invite you to stay with us for the afternoon to continue the conversation or work on your own projects. We provide chairs, tables, wireless and a great space. You bring what you need to work with (laptop/mobile). Our open afternoons close at 5pm.

Let us know if you haven’t been to the Studio before and we'll be happy to show you around! Send an email to Jason@pmstudio.co.uk and we will meet you at 12.30pm for a quick tour.
