Making progress: Barriers to success in end-user developers' physical prototyping

Previous research has investigated difficulties faced by novice and end-user programmers and suggested how these could be solved. However, there has been scant research investigating barriers faced by end-user developers (EUDs) constructing and programming physical prototypes, and how these could be overcome. I report the results of an empirical study designed to uncover barriers for EUDs in physical prototyping, with a view to design support for overcoming them.
