Ben,
I was injured playing college football (severely herniated L4-S1) and I am limited to running only on a treadmill, which is extremely boring... However, I have always had this dream that if one could run on a treadmill and game at the same time it might revolutionize the country!!! Ok maybe that is a little over the top but seriously that would help people get in shape!! Motion gaming such as the Wii, Move, and Kinect are cool but I want to play the classics... Halo, COD, and etc.
If you could design a controller that was split in two but still kept full functionality in each hand so one could literally sprint while playing games you could start whole gyms based around this concept. It would also be interesting to test how well people can game while under duress or are winded... For example, what is your kill to death ratio while running at 6.0 on the treadmill?? Is there a median average?? Could this revolutionize Madden??
That is my idea and I swear if I had Ben's know how I would be on it!! NO I DO NOT WANT A REGULAR CONTROLLER ATTACHED TO A TREADMILL!!
