And I don’t mean data persistence here. More than two years ago I was a member of Imagine Cup team. We were competing in an embedded category, and our subject was IdeoGraph (IdeoGraph Imagine Cup report).  Main part of this system was an IdeoPen, 3D pointing device that was a size of and looked like a real pen. It’s main part were 3 3-axis accelerometers so we were able to collect any data consisting it’s location in 3D space. The idea was great, possibilities were infinite, “sky was a limit”. We made it to the Polish finals, and well, that was all. We were thinking about making it a more mature product, but an overwhelming amount of mundane things took all of our free time and in the end IdeoGraph was forgotten.

Then about two years later Sony has shown their new controller. And yes, it’s basically the same idea, I think that even the same technology, but their product was finished, polished and was shown to public. Who knows what would have happened if we were more persistent ? I guess that lesson was learned.
