I am interested in prototyping and developing gadgets and devices using arduino board and other stuffs, however I only get tutorials on arduino but not in interface prototyping. I found a book but it is in other language not in English (link is :http://prototypinginterfaces.com/)
I also don't know the exact term to look for in Google, for tutorials. That might be the reason why I'm not getting the suitable results. Basically what I want to learn is the same as the book says.
I have no idea from where do I start, and what to look for at first. If anybody can help me, please.
