How to fit interaction design into a user story

Following the last session which looked at how to write a user story, this session will specifically discuss how to fit interaction design (http://en.wikipedia.org/wiki/Interaction_design) into user stories. Does interaction design try to influence the design of the solution? Does interaction design conflict with agile principles?

The event will be held in the upstairs room at The Plumbers Arms. The sessions are informal and we are happy for you to eat the pub grub / drink during the meetup (the pies are pretty nice).

The pub's site gives directions: http://www.taylor-walker.co.uk/pub/plumbers-arms-belgravia/c0685/
